ABPS101 Introduction to Abnormal Psychology Notes (PIHE): Pearson Institute Exam Notes for South African Students

ABPS101 Introduction to Abnormal Psychology is a foundational module in the Pearson Institute of Higher Education (PIHE) BPsych Equivalent Programme. These notes are designed for exam preparation, revision, and structured understanding of abnormal psychology as taught in a South African higher-education context, with practical links to counselling, clinical assessment, diagnosis, and treatment. The emphasis falls on core concepts, major theoretical approaches, DSM-based classification, and the social and cultural realities that shape mental health in South Africa.

1. What Abnormal Psychology Studies and Why It Matters

Abnormal psychology is the branch of psychology that examines patterns of thoughts, emotions, and behaviours that are considered atypical, distressing, dysfunctional, or harmful. It is not simply the study of “madness” or extreme disorders; rather, it is a systematic field concerned with understanding why some people experience psychological suffering, how disorders are identified, and what forms of intervention are most effective. In an introductory module such as ABPS101, the first task is to build a disciplined vocabulary for talking about mental disorder without reducing people to labels.

At the centre of abnormal psychology is the question: What counts as abnormal? There is no single answer, because abnormality is not defined only by statistics or by whether a person behaves differently from the majority. Instead, abnormal psychology relies on a cluster of criteria that include statistical rarity, deviation from social norms, personal distress, maladaptive functioning, and risk of harm. These criteria help students avoid simplistic thinking. For example, a highly creative person may behave unusually, but if that person is functioning well, not distressed, and not harming others, unusualness alone does not equal disorder. Likewise, a person may appear “normal” in public while experiencing severe internal distress, panic attacks, obsessive thoughts, or depression.

1.1 Definitions of Abnormality

A standard exam answer should explain that abnormality is usually understood through several overlapping perspectives:

1. Statistical infrequency
   Behaviour or traits are considered abnormal if they occur rarely in a population. This is useful for describing extreme intellectual disability or exceptionally severe symptoms, but it is not enough on its own. High intelligence is statistically rare, yet it is not a disorder.

2. Deviation from social norms
   Behaviour that violates expected cultural or social rules may be judged abnormal. This criterion is strongly influenced by culture and history. For example, hearing the voice of an ancestor may be meaningful in one cultural setting and alarming in another. Social norms also change over time, which is why psychiatry must be cautious about using this criterion alone.

3. Subjective distress
   A person may be considered abnormal when they experience intense emotional suffering, fear, guilt, or despair. Depression, panic disorder, and post-traumatic stress often involve severe distress even when external behaviour seems controlled.

4. Maladaptiveness or dysfunction
   This criterion asks whether behaviour interferes with daily life, relationships, work, or self-care. A behaviour is especially concerning when it prevents a person from meeting ordinary demands. For example, compulsive washing may temporarily reduce anxiety but ultimately disrupt normal functioning.

5. Dangerousness
   In some cases, abnormality is linked to risk of harm to self or others. This criterion must be used carefully because it can lead to stigma if people with mental illness are assumed to be violent. In reality, many people with mental disorders are more likely to be victims than perpetrators of violence.

1.2 The Importance of Context

In South Africa, students should pay attention to cultural context, poverty, trauma exposure, and unequal access to mental healthcare. Symptoms do not exist in a vacuum. A person living with unemployment, housing insecurity, and violent neighbourhood conditions may show distress that cannot be understood only in terms of individual pathology. Abnormal psychology therefore overlaps with social psychology, public health, and community psychology.

For exam purposes, it is helpful to distinguish between symptoms and disorders. A symptom is a sign or experience, such as sadness, insomnia, or intrusive thoughts. A disorder is a pattern of symptoms that clusters together in a clinically significant way and causes impairment or distress. One symptom alone does not establish a diagnosis. For instance, feeling nervous before an exam is normal, but persistent fear of social scrutiny across many situations may indicate social anxiety disorder.

1.3 Historical Attitudes Toward Mental Disorder

Abnormal psychology also studies how societies have interpreted mental disturbance over time. Historically, people explained unusual behaviour through supernatural forces, punishment, witchcraft, or possession. In some periods, people with severe mental illness were isolated in institutions or treated brutally. Later, more humane approaches emerged, including moral treatment and scientific classification.

A basic historical sequence for exam revision is:

• Supernatural explanations: evil spirits, curses, divine punishment
• Biological explanations: brain disease, heredity, nervous system dysfunction
• Psychological explanations: trauma, learning, cognition, family dynamics
• Sociocultural explanations: poverty, discrimination, culture, stress
• Integrated biopsychosocial explanations: combining all of the above

This historical development matters because modern abnormal psychology does not rely on a single cause. It recognises that mental disorders are usually produced by multiple interacting factors.

1.4 Why the Field Matters in a PIHE Context

For PIHE students, abnormal psychology is not only about passing tests. It prepares learners for professional thinking in counselling, case formulation, ethics, referral decisions, and client-centred communication. Students must develop the habit of asking:

• What is the presenting problem?
• How severe is it?
• How long has it lasted?
• What is the effect on functioning?
• What risks are present?
• What contextual pressures may be contributing?
• What strengths and protective factors are available?

These questions guide responsible practice. They also protect against overdiagnosis, misdiagnosis, and stigma. An introductory module such as ABPS101 builds the foundation for more advanced work in psychopathology, assessment, intervention, and mental health law.

1.5 Core Principles to Remember

A concise revision summary for this section is:

• Abnormal psychology studies patterns of behaviour, emotion, and cognition that are clinically significant.
• There is no single definition of abnormality.
• Context and culture are essential.
• Distress and dysfunction matter more than mere oddness.
• Mental health should be understood through biological, psychological, and social lenses.
• The field aims not only to classify disorders, but also to reduce suffering and improve functioning.

A strong exam answer should always show awareness that abnormality is not identical to difference. Human beings vary widely, and only some forms of difference become disordered when they cause suffering, impairment, or danger.

2. Theoretical Perspectives in Abnormal Psychology

Abnormal psychology uses several major perspectives to explain why disorders develop and persist. No single theory explains every disorder fully. Instead, each perspective highlights certain causes while downplaying others. Exam answers often improve when they compare perspectives and show how they complement one another rather than treating them as competitors that cancel each other out.

2.1 The Biological Perspective

The biological perspective explains abnormal behaviour in terms of genetics, brain structure, neurotransmitters, hormones, and physiological processes. It assumes that mental disorders are at least partly related to bodily mechanisms. This view is especially important in disorders such as schizophrenia, bipolar disorder, major depression, and anxiety disorders, where biological vulnerability often interacts with stress.

Key biological ideas include:

• Genetics and heredity: Some disorders run in families. A family history may increase risk, though it does not guarantee illness.
• Neurotransmitter imbalance: Chemical messengers such as serotonin, dopamine, and norepinephrine play a role in mood, motivation, and perception.
• Brain structure and function: Differences in the amygdala, prefrontal cortex, hippocampus, or other regions may be associated with certain disorders.
• Endocrine and immune functioning: Stress hormones and immune responses can influence mental and physical health.
• Diathesis-stress model: A genetic or biological vulnerability may remain latent until environmental stress activates it.

The biological perspective is valuable because it supports medication and medical assessment. However, it can become reductive if it ignores trauma, learning, culture, or social stress. For example, a student experiencing panic symptoms may be biologically sensitive, but ongoing financial pressure or family conflict may be the immediate trigger.

2.2 The Psychodynamic Perspective

The psychodynamic perspective originates in the work of Sigmund Freud and later theorists. It explains abnormal behaviour as the result of unconscious conflict, unresolved early childhood experiences, and defence mechanisms used to manage anxiety. According to this view, symptoms are not random; they are meaningful expressions of hidden conflict.

Important psychodynamic ideas include:

• Unconscious processes: Thoughts and desires outside awareness influence behaviour.
• Conflict among id, ego, and superego: Internal tension can produce anxiety and symptoms.
• Defence mechanisms: Repression, denial, projection, displacement, and rationalisation protect the person from distress.
• Fixation and developmental stages: Early developmental disruptions may affect later personality and coping.
• Transference: Feelings toward important early figures may be redirected to the therapist.

This approach is historically important because it introduced the idea that symptoms could have psychological meaning and that childhood matters. Its limitations include weak empirical support for some of Freud’s specific claims and difficulty testing unconscious processes directly. Nonetheless, the psychodynamic tradition remains influential in understanding personality disorders, relational difficulties, and the impact of early attachment experiences.

2.3 The Behavioural Perspective

The behavioural perspective focuses on observable behaviour and the role of learning. It holds that abnormal behaviour is acquired and maintained through classical conditioning, operant conditioning, and observational learning. This perspective is especially useful for understanding phobias, avoidance, compulsions, and certain habits.

Key behavioural principles include:

• Classical conditioning: A neutral stimulus becomes associated with fear or anxiety after being paired with a frightening event.
• Operant conditioning: Behaviour is strengthened by reinforcement. Avoidance reduces anxiety temporarily, so the avoidance pattern persists.
• Observational learning: A person may learn fears or coping patterns by watching others.
• Behavioural avoidance: Avoidance prevents corrective learning and maintains anxiety.

A classic example is someone who develops a dog phobia after being bitten. The bite is the unconditioned aversive event, the dog becomes associated with fear, and future avoidance of dogs is negatively reinforced because it reduces anxiety. Behavioural treatment often uses exposure, systematic desensitisation, and reinforcement strategies.

The strength of the behavioural model is its practical clarity and strong treatment applications. Its weakness is that it may underplay internal thoughts, biological predispositions, and deeper emotional meanings.

2.4 The Cognitive Perspective

The cognitive perspective argues that abnormal behaviour is shaped by distorted thinking patterns, maladaptive beliefs, and biased interpretations of events. People do not respond to reality purely as it is; they respond to how they interpret it. Depression, anxiety, and some personality difficulties are strongly linked to cognitive distortions.

Common cognitive distortions include:

• All-or-nothing thinking
• Catastrophising
• Overgeneralisation
• Mind reading
• Selective abstraction
• Personalisation
• Negative self-schemata

For example, a student who receives a low mark may conclude, “I am worthless and I will fail everything,” rather than “I did badly on one assignment and need to improve.” Such thinking can intensify depression and hopelessness. Cognitive therapies aim to identify, challenge, and restructure these patterns.

This perspective is highly influential in modern psychotherapy because it offers clear methods for assessment and intervention. It also helps explain why two people can experience the same event very differently depending on their beliefs, expectations, and self-concept.

2.5 The Humanistic Perspective

The humanistic perspective emphasises personal growth, self-actualisation, freedom, meaning, and subjective experience. It views psychological distress as arising when a person’s real self and ideal self are in conflict, or when the environment prevents healthy growth. Carl Rogers is central here, especially with the concepts of unconditional positive regard, congruence, and empathy.

Humanistic ideas remind students that clients are not merely symptom collections. They are persons with dignity, needs, values, and potential. The limitation of the humanistic approach is that it may be too optimistic about human freedom and may not adequately explain severe psychosis or biological disorders. Still, its emphasis on empathy and meaning remains crucial in counselling relationships.

2.6 The Sociocultural Perspective

The sociocultural perspective examines how family, peers, gender roles, race, class, religion, and culture influence abnormal behaviour. A person’s symptoms must be interpreted within their social environment. This is especially important in South Africa, where historical inequality, discrimination, and economic disadvantage shape mental health outcomes.

This perspective highlights:

• Family systems: Patterns of communication, conflict, attachment, and support
• Social stressors: Poverty, unemployment, violence, migration, and trauma
• Cultural norms: Expectations about emotion, authority, gender, and spirituality
• Stigma and exclusion: Social attitudes that intensify distress and delay treatment
• Structural inequality: Unequal access to education, housing, healthcare, and safety

The sociocultural perspective is essential because mental health is not only an individual matter. A person may be struggling because of chronic stress, community violence, or systemic exclusion. A good abnormal psychology answer should always consider these layers.

2.7 The Biopsychosocial Model

The most useful contemporary framework is the biopsychosocial model, which integrates biological, psychological, and social causes. This model avoids the mistake of blaming a single factor. For example, depression may involve genetic risk, negative thinking patterns, loss, and social isolation. Anxiety may reflect temperament, conditioning, family modelling, and ongoing stress.

The model is often examined because it reflects modern clinical thinking. It supports a holistic understanding of mental disorder and encourages combined interventions such as medication, psychotherapy, lifestyle support, and social assistance when appropriate.

2.8 Comparing Perspectives in an Exam

A strong exam response may compare the perspectives as follows:

• Biological: explains bodily and genetic contributions
• Psychodynamic: explains unconscious conflict and early development
• Behavioural: explains learning and reinforcement
• Cognitive: explains distorted thinking and beliefs
• Humanistic: explains blocked growth and loss of meaning
• Sociocultural: explains environment, culture, and structural stress

The best conclusion is that each perspective offers a partial truth. Abnormal psychology becomes more accurate when these perspectives are combined thoughtfully rather than treated as isolated dogmas.

3. Classification, Diagnosis, and Assessment

Classification and diagnosis are central to abnormal psychology because they provide a shared language for identifying patterns of disorder. Without classification, clinicians would struggle to communicate, compare cases, or select evidence-based treatments. However, classification is never neutral or perfect. It can simplify complex lives, create stigma, and sometimes overpathologise ordinary distress. Students must therefore understand both the usefulness and the limits of diagnostic systems.

3.1 Why Classification Is Used

Classification allows professionals to:

1. Communicate clearly using common terminology
2. Organise symptoms into recognisable patterns
3. Guide treatment choices
4. Predict likely course and prognosis
5. Support research and epidemiological study
6. Assist with service planning and referral

For example, a clinician who identifies major depressive disorder can consider therapies that have been tested for depression, estimate risk factors such as suicidality, and monitor symptom severity over time. Classification turns a confusing set of complaints into something clinically workable.

3.2 The DSM and ICD Traditions

Most introductory abnormal psychology modules discuss major diagnostic systems such as the DSM (Diagnostic and Statistical Manual of Mental Disorders) and the ICD (International Classification of Diseases). In many international and South African contexts, these systems provide the framework for diagnosis. Students should understand that they are manuals for grouping symptoms, not magical labels that capture a person’s entire identity.

Diagnostic systems generally specify:

• Diagnostic criteria
• Duration thresholds
• Exclusion rules
• Severity indicators
• Functional impairment requirements

A person is not diagnosed only because they feel sad, anxious, or unusual. The pattern must meet formal criteria and cause clinically significant distress or impairment.

3.3 Reliability and Validity in Diagnosis

Two key concepts in assessment are reliability and validity.

• Reliability refers to consistency. If two clinicians assess the same person, they should ideally reach similar conclusions.
• Validity refers to whether a diagnosis truly captures the condition it claims to describe.

A diagnosis may be reliable but not valid if clinicians consistently agree on a category that does not actually reflect a distinct disorder. Conversely, a diagnosis may seem valid in theory but be applied inconsistently, reducing reliability.

Assessment improves reliability through structured interviews, standardised tools, and clear criteria. Validity improves when diagnoses match observed patterns, biological findings, treatment response, and real-world impairment.

3.4 Clinical Assessment Methods

Assessment in abnormal psychology combines several sources of information. A competent examiner does not rely on a single method.

3.4.1 Clinical Interview

The clinical interview is a conversation used to gather information about symptoms, history, family background, substance use, stressors, and functioning. It can be structured, semi-structured, or unstructured. The structured interview improves consistency; the unstructured interview allows flexibility and rapport.

3.4.2 Mental Status Examination

A mental status examination evaluates appearance, behaviour, speech, mood, affect, thought form, thought content, perception, cognition, insight, and judgment. It helps identify severe disturbances such as psychosis, cognitive impairment, or suicidal risk.

3.4.3 Psychological Testing

Standardised tests can assess intelligence, personality, mood, trauma, or specific symptoms. Their value depends on proper administration and interpretation. Tests are not substitutes for clinical judgment; they complement it.

3.4.4 Behavioural Observation

Observation of actual behaviour is useful, especially in children, people with developmental disorders, or individuals whose self-report may be limited.

3.4.5 Collateral Information

Family members, teachers, medical records, or prior clinicians may provide information that fills gaps in the person’s own report. This is especially important when insight is poor.

3.5 Steps in a Good Diagnostic Process

A practical sequence for diagnosis includes:

1. Identify the presenting problem
2. Gather history and symptom detail
3. Assess duration, intensity, and frequency
4. Evaluate impairment and distress
5. Rule out medical and substance-related causes
6. Consider cultural factors
7. Compare symptoms to diagnostic criteria
8. Assess risk and urgency
9. Formulate a provisional diagnosis if appropriate
10. Plan treatment or referral

This sequence prevents rushed or careless diagnosis. It also reminds students that diagnosis is a process, not a one-time verdict.

3.6 The Problem of Labelling and Stigma

Classification can help, but it can also harm. Labels may cause people to be seen only through the lens of illness. A person diagnosed with schizophrenia may be treated as unpredictable or dangerous even when they are not. A person with depression may be told to “snap out of it.” Such responses deepen suffering and discourage help-seeking.

Stigma has several forms:

• Public stigma: negative attitudes from society
• Self-stigma: internalised shame
• Structural stigma: policies and institutions that limit access or rights

A sensitive examiner should note that diagnosis should support care, not identity reduction. The goal is not to define the person by the disorder, but to understand the disorder in the person.

3.7 Differential Diagnosis and Comorbidity

Two further concepts are essential:

• Differential diagnosis means distinguishing one disorder from another that has similar symptoms. For example, panic disorder, hyperthyroidism, and substance intoxication may all produce palpitations and anxiety.
• Comorbidity means the presence of more than one disorder at the same time. Depression and anxiety often co-occur, as do substance use and trauma-related problems.

Comorbidity is common and important because it complicates treatment and may reflect shared underlying vulnerabilities. A client with depression may also have alcohol misuse, chronic pain, and unresolved grief. Such complexity is normal in real clinical work.

3.8 Cultural Assessment

Cultural factors must be included in diagnosis. Behaviour judged abnormal in one setting may be understandable in another. A culturally competent assessment asks about:

• Language and meaning
• Spiritual beliefs
• Migration and identity
• Family structure and decision-making
• Help-seeking expectations
• Cultural expressions of distress

This is particularly relevant in South Africa, where diverse languages, traditions, and belief systems shape how symptoms are described and interpreted. A responsible diagnostic approach seeks understanding before judgment.

4. Major Categories of Mental Disorders

Introductory abnormal psychology generally surveys the most important disorder groups rather than every specific diagnosis in detail. Students should know the broad categories, typical symptoms, key theories, and basic treatment approaches. The goal is not memorising isolated lists but understanding how symptom clusters are organised.

4.1 Anxiety Disorders

Anxiety disorders involve excessive fear, worry, avoidance, or physiological arousal that is out of proportion to the situation and interferes with functioning. Common forms include generalised anxiety disorder, panic disorder, phobias, and social anxiety disorder.

Typical features include:

• Persistent worry
• Restlessness
• Muscle tension
• Sleep disturbance
• Rapid heartbeat
• Avoidance behaviour

The behavioural perspective explains anxiety as learned fear, while the cognitive perspective points to catastrophic thinking and threat bias. Biological factors such as temperament and nervous system sensitivity also matter.

A useful example is social anxiety disorder. A student may fear humiliation in class, avoid presentations, and interpret ordinary mistakes as evidence of incompetence. Avoidance reduces anxiety temporarily but maintains the problem over time because the person never learns that the feared situation may be survivable.

4.2 Mood Disorders

Mood disorders primarily affect emotional state. The major forms usually studied at introductory level are depressive disorders and bipolar disorders.

4.2.1 Depression

Depression can involve:

• Low mood
• Loss of interest or pleasure
• Fatigue
• Changes in appetite or sleep
• Feelings of worthlessness or guilt
• Difficulty concentrating
• Suicidal thoughts in severe cases

The cognitive model explains depression through negative thinking about the self, world, and future. The learned helplessness idea suggests that repeated experiences of failure or uncontrollable stress can produce hopelessness. Biological vulnerabilities and social losses often contribute as well.

4.2.2 Bipolar Disorder

Bipolar disorders involve episodes of depression and mania or hypomania. Mania may include elevated mood, decreased need for sleep, rapid speech, grandiosity, impulsive behaviour, and risky decision-making. The condition illustrates why mood disorders are not all the same: depression is not merely sadness, and mania is not simple happiness. Mania can cause severe impairment and danger.

4.3 Trauma- and Stressor-Related Disorders

These disorders arise following exposure to traumatic or highly stressful events. They include acute stress reactions, post-traumatic stress disorder, and related adjustment problems.

Important symptoms may include:

• Intrusive memories or flashbacks
• Avoidance of reminders
• Hypervigilance
• Sleep disturbance
• Emotional numbing
• Irritability
• Negative changes in mood and beliefs

Trauma-focused explanations emphasise both the event and the person’s response to it. Trauma exposure is especially significant in contexts where violence, accidents, abuse, or disaster are common. The presence of trauma does not guarantee PTSD, because resilience, support, and coping resources influence outcomes. Nonetheless, trauma can alter perception, memory, and bodily arousal in enduring ways.

4.4 Obsessive-Compulsive and Related Disorders

Obsessive-compulsive problems involve unwanted thoughts, urges, or images and repetitive behaviours or mental acts performed to reduce distress. Obsessions are intrusive and often irrational; compulsions are rituals that temporarily relieve anxiety.

Examples include:

• Fear of contamination and repeated washing
• Repeated checking of locks or appliances
• Counting or arranging in a rigid way
• Mental prayers or silent rituals

The behavioural view explains compulsions as negatively reinforced actions, while cognitive theory emphasises inflated responsibility and threat misinterpretation. A student should recognise that compulsions are not “habits” in the ordinary sense; they are anxiety-driven responses that become self-perpetuating.

4.5 Psychotic Disorders

Psychotic disorders involve a loss of contact with reality in areas such as perception, thought, or belief. Symptoms may include hallucinations, delusions, disorganised speech, and disorganised behaviour. Schizophrenia is the most widely known psychotic disorder.

Common features include:

• Hallucinations: perceptions without external stimulus, often auditory
• Delusions: fixed false beliefs resistant to evidence
• Disorganised thought: loose associations, derailment, incoherence
• Negative symptoms: reduced emotional expression, avolition, social withdrawal

The causes of psychosis are complex and likely involve genetic risk, brain differences, stress, substance use, and developmental factors. It is essential to avoid romanticising psychosis or reducing it to a single cause. Early intervention can make a substantial difference in prognosis.

4.6 Personality Disorders

Personality disorders are enduring patterns of inner experience and behaviour that deviate from cultural expectations, are inflexible, and lead to distress or impairment. They often affect relationships, self-image, and impulse control.

Broad themes may include:

• Fear of abandonment
• Emotional instability
• Grandiosity
• Distrust
• Social withdrawal
• Rule-breaking or manipulation
• Perfectionism and rigidity

Students should note that personality disorders are complex and often linked to developmental history, attachment patterns, temperament, and environmental adversity. They are not simply “bad personality” problems. They are enduring patterns that become maladaptive.

4.7 Substance-Related and Addictive Disorders

Substance-related disorders involve problematic use of alcohol, drugs, or other psychoactive substances. Addiction is not merely a lack of willpower. It often involves tolerance, withdrawal, craving, impaired control, and continued use despite harm.

Important contributing factors include:

• Peer influence
• Availability of substances
• Stress and coping motives
• Family history
• Reward pathways in the brain
• Trauma and self-medication

A person may initially use substances to reduce anxiety or emotional pain, but repeated use can produce dependency and worsen mental health. Co-occurring substance use and other disorders are common, requiring integrated treatment.

4.8 Neurodevelopmental and Cognitive Disorders

Although often covered in more specialised modules, introductory abnormal psychology may mention conditions involving early developmental differences or cognitive decline. Attention difficulties, intellectual disability, and some forms of dementia highlight the importance of brain development, learning, and ageing.

The essential point is that abnormal psychology covers the lifespan. Mental disorder is not confined to adulthood, and not all distress is emotional. Some difficulties involve language, attention, memory, or adaptive functioning.

4.9 Comparative Summary Table

Disorder Group	Core Features	Common Risks	Broad Treatment Directions
Anxiety disorders	Excessive fear, worry, avoidance	Stress, learned fear, family history	CBT, exposure, medication in some cases
Mood disorders	Persistent sadness or elevated mood	Loss, cognition, biology, sleep disruption	Psychotherapy, medication, lifestyle support
Trauma-related disorders	Intrusions, avoidance, hyperarousal	Trauma exposure, low support	Trauma-focused therapy, stabilisation
OCD-related disorders	Obsessions and compulsions	Threat sensitivity, reinforcement	Exposure and response prevention
Psychotic disorders	Hallucinations, delusions, disorganisation	Genetic vulnerability, stress, substances	Medication, psychosocial support
Personality disorders	Enduring maladaptive patterns	Early adversity, temperament	Long-term psychotherapy, skills training
Substance-related disorders	Compulsive use and dependence	Peer influence, coping, biology	Detox, counselling, relapse prevention

This table should not be memorised mechanically. Instead, use it to compare disorder families in terms of symptoms, causes, and interventions.

5. Risk Factors, Treatment Principles, and South African Exam Focus

The final area of ABPS101 requires students to think beyond symptom lists and ask why disorders develop, how they are managed, and what ethical issues shape care. This section is often where strong exam answers distinguish themselves, because it brings together theory, practice, and context.

5.1 Risk and Protective Factors

Mental disorders are rarely caused by one isolated event. They emerge from the interaction of risk and protective factors.

5.1.1 Risk Factors

Risk factors increase the likelihood of disorder. They may include:

• Genetic vulnerability
• Early attachment disruption
• Childhood abuse or neglect
• Chronic stress
• Poverty and unemployment
• Social isolation
• Substance misuse
• Family conflict
• Traumatic experiences
• Poor physical health
• Sleep deprivation

5.1.2 Protective Factors

Protective factors reduce risk or improve resilience. They may include:

• Stable relationships
• Supportive family or community
• Problem-solving skills
• Faith or spiritual coping
• Access to healthcare
• Good nutrition and sleep
• School or work engagement
• Sense of meaning and identity
• Emotional regulation skills

A person with many risk factors may still remain relatively well if protective factors are strong. Likewise, someone with fewer obvious risks may become unwell if stressors accumulate and support is lacking. This is why biopsychosocial formulation is more useful than simplistic cause-and-effect thinking.

5.2 Stress, Coping, and Resilience

Stress is not automatically harmful. Some stress can motivate performance and growth. Problems arise when stress is prolonged, severe, or combined with limited coping capacity. Coping refers to the strategies people use to manage stress.

Broad coping styles include:

• Problem-focused coping: addressing the source of stress directly
• Emotion-focused coping: managing emotional response
• Avoidant coping: escaping, denying, or suppressing stressors

Avoidant coping may offer short-term relief but often maintains symptoms. Resilience is the ability to adapt, recover, and continue functioning despite adversity. Resilience is not a fixed trait; it is shaped by supports, skills, and opportunities.

5.3 Principles of Treatment

Treatment should be based on assessment, diagnosis, severity, and client needs. Different disorders require different approaches, but several broad principles recur across the field.

5.3.1 Psychological Treatments

Psychological therapies may include:

• Cognitive-behavioural therapy (CBT) for anxiety, depression, and related disorders
• Exposure-based therapies for phobias and OCD
• Psychodynamic therapy for relational and personality issues
• Humanistic counselling for growth, self-acceptance, and meaning
• Family or systemic approaches where relational patterns are central

Therapy works best when it is collaborative, ethically grounded, and adapted to the client’s context.

5.3.2 Biological Treatments

Biological interventions may include medication, hospital care, or medical monitoring. Medication can be essential in severe depression, psychosis, bipolar disorder, and some anxiety disorders. However, medication is not a universal solution and should be paired with appropriate follow-up and psychosocial support where possible.

5.3.3 Combined Approaches

Many clients benefit from combined treatment. For example, a person with panic disorder may improve through CBT and, in some cases, medication. A person with depression may need therapy, medication, sleep improvement, and social support. Integrated care reflects the complexity of mental health.

5.4 Ethical Issues in Abnormal Psychology

Ethics are central to diagnosis and intervention. Students should understand the importance of:

• Confidentiality
• Informed consent
• Competence
• Non-maleficence: do no harm
• Beneficence: act in the client’s best interests
• Respect for dignity and autonomy
• Cultural sensitivity
• Boundary management

Ethical practice is especially important when clients are vulnerable, fearful, or experiencing impaired judgment. Poorly handled assessment can deepen shame or discourage future help-seeking.

5.5 South African Context and PIHE Relevance

For South African students, abnormal psychology must be understood against a backdrop of inequality, service gaps, and diverse cultural realities. Mental health care is affected by:

• Unequal access between urban and rural areas
• Cost barriers in private care
• Under-resourced public services
• High exposure to violence and trauma
• Cultural and language differences in help-seeking
• Stigma surrounding psychiatric treatment

In practical terms, this means students should be able to discuss not only symptoms but also social determinants. A client’s distress may be intensified by unemployment, unsafe transport, overcrowding, food insecurity, or family burden. In the South African setting, effective abnormal psychology must therefore be both clinically informed and socially aware.

5.6 How to Answer ABPS101 Exam Questions

A strong ABPS101 answer should show structure, accuracy, and integration. When asked to discuss a disorder or concept, students should generally:

1. Define the concept clearly
2. Identify the main symptoms or features
3. Explain relevant theories or causes
4. Mention assessment or diagnostic issues
5. Include treatment or intervention principles
6. Apply the concept to a realistic example
7. Conclude with a balanced summary

For example, if asked about depression, do not merely list sadness and fatigue. Explain that depression involves persistent low mood and loss of interest, may be linked to cognitive distortions, biological vulnerability, and environmental stress, can be assessed through interview and symptom criteria, and is commonly treated with CBT, medication, or both depending on severity.

5.7 High-Yield Revision Points

The most important points to remember for revision are:

• Abnormal psychology studies distress, dysfunction, and atypical behaviour.
• Abnormality must be understood in cultural and contextual terms.
• Biological, psychological, and sociocultural perspectives all contribute.
• Diagnosis helps organise care but must be used cautiously.
• Anxiety, mood, trauma-related, psychotic, personality, and substance-related disorders are major categories.
• Risk and protective factors shape vulnerability and resilience.
• Treatment may be psychological, biological, or combined.
• Ethics and cultural competence are essential in South African practice.

5.8 Final Integrative Summary

ABPS101 Introduction to Abnormal Psychology provides the conceptual foundation for understanding mental disorder in a humane, scientific, and context-sensitive way. It teaches that abnormal behaviour is not simply strange behaviour, but a pattern of suffering or impairment shaped by biology, learning, thought, trauma, and social environment. It also teaches caution: diagnosis can aid treatment, but it must never erase the person behind the diagnosis.

For PIHE students, mastery of this module means being able to define key terms, compare theoretical perspectives, recognise major disorder groups, explain how assessment works, and think ethically about mental health in South Africa. A well-prepared student should be able to move from theory to application, from symptom to formulation, and from classification to compassionate understanding. That is the real purpose of abnormal psychology: not to label people carelessly, but to understand distress clearly enough to respond helpfully.
