This study guide provides a comprehensive, exam-focused treatment of Abnormal Behaviour and Mental Health (PYC3702) as commonly studied in South African universities, with particular attention to UNISA-style assessment expectations. It explains core concepts, major theoretical approaches, diagnostic frameworks, key disorders, treatment principles, and the social and ethical issues that shape mental health practice in South Africa. The notes are designed to support revision, essay preparation, and applied exam answering with clear definitions, examples, and structured comparisons.
1. Foundations of Abnormal Behaviour and Mental Health
Understanding abnormal behaviour
The study of abnormal behaviour begins with a deceptively simple question: what counts as abnormal? In everyday language, people often use the term to mean strange, unusual, shocking, or socially unacceptable. In psychology, however, abnormal behaviour is not defined by a single feature. A behaviour, thought pattern, or emotional response is usually considered abnormal when it significantly deviates from social expectations, causes distress, interferes with functioning, or reflects patterns associated with mental disorder. Because no single criterion is sufficient on its own, psychologists use a combination of indicators.
A useful starting point is the four D’s:
- Deviation: behaviour differs from cultural or social norms.
- Distress: the person experiences emotional pain or suffering.
- Dysfunction: behaviour disrupts daily life, work, relationships, or self-care.
- Danger: the person may pose a risk to self or others.
These are helpful because they show that abnormality is not simply about being unusual. A highly creative person may deviate from the norm without being mentally ill. A person may also be distressed, such as after bereavement, without necessarily having a disorder. For exam purposes, it is important to show that abnormal behaviour is context-dependent and must be assessed carefully.
Historical views of mental illness
Ideas about abnormal behaviour have changed dramatically over time. In ancient times, some societies explained unusual behaviour through supernatural causes, including spirit possession, witchcraft, punishment by gods, or demonic influence. Treatments were often harsh and included exorcism, confinement, starvation, or physical punishment. While these explanations are now scientifically rejected, they remain historically important because they influenced attitudes of fear and stigma.
During the 19th century, a more humane approach began to emerge. The rise of moral treatment emphasized kindness, order, fresh air, structured routines, and respectful care. This shift paved the way for modern psychiatric institutions, although many institutions later became overcrowded and custodial rather than therapeutic. The medical model became influential as clinicians increasingly viewed mental disorders as illnesses with biological causes that could be diagnosed and treated. This approach led to important developments such as classification systems, psychiatric medication, and hospital-based care.
Modern psychology has moved beyond any single explanation. Contemporary views recognize that mental health problems arise from a complex interaction of biological, psychological, and social factors. This is often referred to as the biopsychosocial model. For example, a person with depression may have a genetic vulnerability, a history of negative thinking, and ongoing stress from poverty or relationship conflict. Understanding this complexity is essential in South African contexts where inequality, trauma, unemployment, and unequal access to healthcare strongly affect mental health outcomes.
Criteria for identifying abnormality
When psychologists and psychiatrists assess abnormal behaviour, they typically ask whether the pattern meets several broad criteria.
-
Statistical rarity
Behaviour that is very uncommon may be considered abnormal. For example, a very high IQ is statistically rare, but it is not a disorder. Statistical rarity is useful for identifying outliers, but it cannot define mental illness on its own. -
Social norm violation
Behaviour that breaks social expectations may be seen as abnormal. However, norms differ across cultures, age groups, and communities. What is acceptable in one setting may be unacceptable in another. -
Personal distress
If a person feels intense sadness, anxiety, shame, or fear, this may indicate a psychological problem. Yet not all disorders cause immediate distress to the person; sometimes family members or society notice the dysfunction first. -
Maladaptiveness
Behaviour is maladaptive when it interferes with the person’s ability to live effectively. Substance dependence, severe avoidance, or compulsive rituals often fall into this category. -
Violation of ideal mental health
Jahoda’s criteria for mental health include self-acceptance, growth, autonomy, accurate perception of reality, environmental mastery, and positive relationships. A person who does not meet these ideals may be struggling psychologically, although this standard is often considered too strict.
Cultural influence and relativism
Abnormality cannot be understood without considering culture. Culture shapes beliefs about illness, emotional expression, family roles, spirituality, and acceptable behaviour. Some experiences that appear unusual in one cultural context may be normal in another. For instance, hearing the voice of an ancestor may be interpreted spiritually rather than clinically in some communities. This does not mean that all culturally meaningful experiences are harmless or that all are beyond psychological concern. Rather, clinicians must distinguish between culturally sanctioned experiences and symptoms that cause distress or impairment.
This is especially relevant in South Africa, where multiple languages, belief systems, and healing traditions coexist. A culturally competent professional considers the client’s background, explanatory models, and community support systems. Cultural sensitivity reduces misdiagnosis and strengthens trust.
Mental health versus mental illness
Mental health is broader than the absence of illness. A person may not meet criteria for a disorder yet still experience poor wellbeing, chronic stress, loneliness, or low functioning. Similarly, someone with a diagnosed disorder may still have strengths, meaningful relationships, and periods of recovery. Exam answers should reflect this distinction: mental health is a continuum, not a simple healthy/unhealthy divide.
A helpful way to remember this is to think of mental health as involving:
- emotional wellbeing,
- psychological resilience,
- effective coping,
- satisfying relationships,
- and functional participation in daily life.
Mental illness, by contrast, refers to clinically significant disturbances in cognition, emotion, or behaviour that are associated with distress or impairment.
Why this foundation matters
Foundational concepts are central in PYC3702 because they frame everything that follows. If abnormal behaviour is misunderstood, then diagnosis, treatment, and social policy all become distorted. For example, if poverty-related distress is treated only as a personal failure, the real causes are ignored. If unusual cultural beliefs are mistaken for pathology, people may be stigmatized unnecessarily. In exams, strong answers show that abnormal behaviour must always be considered in context, with attention to functioning, culture, severity, and causation.
2. Theoretical Approaches to Abnormal Behaviour
The biological perspective
The biological approach explains mental disorders in terms of the body, especially the brain, nervous system, hormones, and genetics. According to this perspective, abnormal behaviour may result from structural brain differences, neurotransmitter imbalances, hereditary vulnerability, brain injury, infection, or medical conditions.
Key biological factors include:
- Genetics: some disorders run in families, suggesting inherited vulnerability.
- Neurotransmitters: chemical messengers such as serotonin, dopamine, and norepinephrine influence mood, motivation, and cognition.
- Brain structure and function: abnormalities in areas such as the amygdala, hippocampus, or prefrontal cortex are linked to anxiety, memory problems, and impulse control.
- Hormones and the endocrine system: stress hormones such as cortisol can affect mood and wellbeing.
- Physical illness or neurological damage: infections, seizures, head injuries, and degenerative conditions can produce psychiatric symptoms.
The biological perspective has major strengths. It is grounded in measurable evidence, has led to effective medications, and helps reduce moral blame by showing that many disorders are not simply matters of weak character. However, it has limitations. Biological reductionism may ignore trauma, relationships, poverty, and meaning. Not every person with depression has the same biological profile, and medication alone may not resolve social stressors that maintain symptoms.
The psychodynamic perspective
The psychodynamic approach, associated with Sigmund Freud, emphasizes unconscious conflict, early childhood experience, and defense mechanisms. According to this view, mental distress can arise when instinctual desires, internalized rules, and reality demands clash. Anxiety and symptoms may be expressions of unresolved conflict.
Important concepts include:
- Id, ego, and superego: the id seeks immediate gratification, the superego represents moral standards, and the ego mediates between them.
- Unconscious processes: thoughts and desires outside awareness may influence behaviour.
- Defense mechanisms: strategies such as repression, denial, projection, displacement, rationalization, and regression help reduce anxiety.
- Early relationships: attachment patterns and childhood experiences shape personality development.
For example, a person who consistently denies anger may develop anxiety or psychosomatic symptoms, while someone who projects unacceptable feelings onto others may become suspicious or hostile. The psychodynamic view has contributed greatly to the understanding of personality, childhood development, and symbolic meaning. Its weakness is that many of its claims are difficult to test empirically, and some explanations can become speculative if not grounded in observable evidence.
The behavioural perspective
The behavioural approach argues that abnormal behaviour is learned through experience. Rather than focusing on hidden motives, it examines observable behaviour and the environmental conditions that shape it. Learning occurs through:
-
Classical conditioning
A neutral stimulus becomes associated with a fearful or distressing response. For example, if a child is bitten by a dog, dogs may later trigger fear. -
Operant conditioning
Behaviour is strengthened or weakened by consequences. Avoidance behaviour may persist because it reduces anxiety, even though it prevents recovery. -
Observational learning
People may learn fears, coping patterns, or aggressive responses by watching others.
The behavioural approach is valuable because it is practical and can be directly applied in treatment, especially through exposure techniques, reinforcement strategies, and skills training. Its limitation is that it can underplay thoughts, emotions, and biological predispositions. Human behaviour is not shaped only by external reinforcement; interpretation and meaning matter too.
The cognitive perspective
The cognitive approach focuses on how people think, interpret, and process information. Psychological distress often arises from distorted beliefs, automatic negative thoughts, and maladaptive assumptions. A person with depression may interpret neutral events as proof of failure, while a person with anxiety may overestimate danger and underestimate coping ability.
Common cognitive distortions include:
- all-or-nothing thinking,
- catastrophizing,
- overgeneralization,
- mind reading,
- emotional reasoning,
- and selective abstraction.
Cognitive theory has transformed therapy by showing that changing thought patterns can reduce symptoms. It explains why two people may experience the same event differently: one may cope, while another becomes overwhelmed. Its limitation is that thoughts do not occur in isolation. They are influenced by mood, biology, trauma, social environment, and habit. Still, in examination answers, cognitive explanations are essential for disorders such as depression, anxiety, OCD, and eating disorders.
The humanistic perspective
Humanistic psychology emphasizes free will, personal meaning, self-actualization, and the inherent value of the person. From this viewpoint, psychological problems emerge when people are blocked from growth or live in conditions that prevent authentic self-expression. Carl Rogers argued that distress develops when there is a mismatch between the real self and ideal self, especially when a person receives conditional positive regard rather than unconditional acceptance.
The humanistic perspective contributes an optimistic view of human potential and stresses empathy, respect, and person-centred therapy. It is especially helpful in counselling and recovery-oriented practice because it avoids reducing people to symptoms. Its weakness is that it offers less precise explanation for severe mental illness and is less easy to test than some other approaches.
The sociocultural perspective
The sociocultural perspective highlights the role of society, community, relationships, discrimination, and broader structural conditions. Mental health is shaped by poverty, unemployment, gender inequality, violence, racism, migration stress, family conflict, and limited access to care. In South Africa, sociocultural factors are especially significant because many people face multiple stressors at once.
Examples include:
- chronic financial pressure contributing to anxiety and depression,
- intimate partner violence increasing trauma-related disorders,
- stigma limiting help-seeking,
- and community violence contributing to hypervigilance and fear.
This perspective helps explain why mental illness rates and treatment outcomes vary across groups. It also reminds exam candidates that mental health is not just an individual matter. Structural inequalities can intensify symptoms and make recovery harder.
Integrating the approaches
No single theory explains all abnormal behaviour. The most useful understanding is integrative. For example, a student who develops panic attacks may have:
- a biological sensitivity to stress,
- a cognitive tendency to misinterpret bodily sensations,
- a behavioural pattern of avoidance,
- and a social environment that intensifies pressure.
An integrated answer in an exam often scores better than a one-sided answer because it shows nuance. The goal is not to choose one perspective as “correct” but to explain how perspectives complement one another. Mental disorders are best understood as multi-determined, meaning they arise from a combination of causes rather than a single source.
3. Classification, Diagnosis, and Assessment
Why classification matters
Classification is the process of grouping symptoms into recognizable categories so that clinicians can communicate clearly, predict likely outcomes, and choose appropriate treatment. Without classification, mental health professionals would have difficulty sharing information or conducting research. Diagnostic systems also help with service planning, policy, and insurance or funding decisions.
At the same time, classification has drawbacks. A diagnosis may oversimplify a person’s experience, create stigma, or encourage the mistaken idea that a disorder is an unchanging entity rather than a pattern of symptoms. In practice, diagnosis should be used as a tool, not as a label that defines the person.
Diagnostic systems
The two most influential systems in current mental health practice are the DSM and the ICD.
DSM
The Diagnostic and Statistical Manual of Mental Disorders is widely used in psychology and psychiatry, especially in research and clinical training. It organizes disorders into categories based on symptom patterns and diagnostic criteria. The DSM is detailed and operationalized, which improves reliability. However, critics argue that it may pathologize normal behaviour and reflect Western assumptions.
ICD
The International Classification of Diseases is the World Health Organization’s system used globally for health diagnosis, including mental disorders. It is especially important in public health and medical settings. In many contexts, including South Africa, ICD coding is highly relevant because it links mental health to broader healthcare systems.
Both systems aim for reliability and validity. Reliability means different clinicians should make similar diagnoses when assessing the same person. Validity means the diagnosis should accurately reflect a real and meaningful syndrome. A classification system may be reliable without being fully valid if clinicians agree on a label that does not capture the underlying condition very well.
The diagnostic process
Assessment begins with information gathering. A clinician may use interviews, observation, psychological tests, collateral information from family, and medical history. Diagnosis is not simply about counting symptoms. It also involves evaluating severity, duration, impairment, risk, and context.
A structured assessment typically asks:
- What symptoms are present?
- How long have they been present?
- How severe are they?
- Do they cause distress or impairment?
- Are there medical or substance-related causes?
- Are the symptoms culturally expected or culturally atypical?
- Is there a risk of self-harm or harm to others?
Careful assessment prevents common errors such as confusing grief with major depression, mistaking trauma reactions for psychosis, or overlooking substance-induced symptoms.
Interviewing and observation
The clinical interview is central to diagnosis. It may be unstructured, semi-structured, or structured. A structured interview follows a fixed set of questions, improving consistency. A semi-structured interview allows the clinician to explore topics flexibly while still covering required areas. Observation can reveal posture, speech, affect, hygiene, eye contact, agitation, or withdrawal.
The mental status examination typically assesses:
- appearance and behaviour,
- speech,
- mood and affect,
- thought process and content,
- perception,
- cognition,
- insight,
- and judgement.
For example, a person with mania may appear overly animated, speak rapidly, and show grandiose ideas. A person with depression may have slowed speech, reduced eye contact, and a flat affect. These observations support but do not replace diagnosis.
Psychological testing
Psychological tests provide standardized information about cognitive functioning, personality traits, emotional symptoms, and risk. Common forms include:
- intelligence tests,
- personality inventories,
- symptom checklists,
- projective methods,
- and neuropsychological assessments.
Testing is useful when interpreted cautiously and alongside other data. No test should be treated as a final answer. Cultural and language differences can affect test performance, making local norms and appropriate interpretation essential.
Reliability and validity in diagnosis
Two key psychometric ideas shape diagnosis.
- Reliability asks whether the assessment is consistent.
- Validity asks whether it measures what it claims to measure.
A diagnosis may be unreliable if two clinicians disagree. It may be invalid if the category does not capture the person’s actual difficulties. Both are important because poor diagnosis leads to poor treatment, misguided research, and weak communication.
Common challenges in diagnosis
Several issues complicate diagnostic work:
- Comorbidity: many people meet criteria for more than one disorder.
- Symptom overlap: anxiety, depression, trauma, and substance use often share features.
- Cultural diversity: symptoms may be expressed differently across groups.
- Stigma and bias: clinicians may overpathologize or underdiagnose certain people.
- Contextual factors: social stress and poverty may mimic or worsen psychiatric symptoms.
- Diagnostic inflation: ordinary sadness, shyness, or stress may be mistaken for illness.
A sophisticated exam answer shows awareness that diagnosis is both necessary and limited. It is a practical map, not the territory itself.
Ethical assessment and professional responsibility
Ethical diagnosis requires respect, informed consent, confidentiality, and sensitivity to power differences. A clinician must avoid careless labelling and should explain findings in a way the client can understand. Risk assessment is also a major ethical duty, especially when there is suicidal ideation, psychosis, severe substance misuse, or vulnerability due to abuse.
In South Africa, assessment should also consider access barriers, language differences, transport challenges, and trauma exposure. A client may appear “non-compliant” when the real issue is lack of money, unstable housing, or fear of stigma. Ethical assessment therefore requires both clinical skill and social awareness.
4. Major Categories of Mental Disorders
Anxiety disorders
Anxiety disorders involve excessive fear, worry, and physiological arousal that are out of proportion to the actual danger or that persist beyond the expected time. Common forms include generalized anxiety disorder, panic disorder, phobias, social anxiety disorder, and obsessive-compulsive disorder, although OCD is now classified separately in many systems.
Typical symptoms include:
- restlessness,
- muscle tension,
- rapid heartbeat,
- shortness of breath,
- sleep disturbance,
- excessive worry,
- avoidance,
- and concentration problems.
Anxiety becomes a disorder when it is persistent, intense, and impairing. For example, a student who worries before an exam is experiencing ordinary anxiety. A student who cannot attend classes, sleep, or concentrate for months because of constant fear may meet criteria for an anxiety disorder.
Treatment often combines psychoeducation, cognitive-behavioural therapy, relaxation skills, and sometimes medication. Exposure-based methods are especially effective for phobias and panic-related avoidance.
Mood disorders
Mood disorders involve disturbances in emotional state, particularly depression and mania.
Depressive disorders
Depression is more than sadness. It may include low mood, loss of interest, fatigue, changes in sleep and appetite, feelings of worthlessness, slowed thinking, and suicidal thoughts. Major depression affects functioning in a profound way and often recurs. Persistent depressive disorder involves chronic low mood over a longer period.
Risk factors include:
- genetic vulnerability,
- trauma,
- chronic stress,
- social isolation,
- medical illness,
- and substance use.
Depression is often misunderstood as laziness or weakness, but this is inaccurate and harmful. In practice, depressed individuals may find even basic tasks overwhelming. Treatment may include psychotherapy, medication, lifestyle support, and crisis intervention where suicidality is present.
Bipolar disorders
Bipolar disorders involve shifts between depression and mania or hypomania. Mania is characterized by elevated or irritable mood, increased energy, decreased need for sleep, racing thoughts, pressured speech, grandiosity, and risky behaviour. Hypomania is less severe but still notable.
A person in mania may spend excessively, drive recklessly, or become highly goal-directed while losing judgement. Because mania can feel pleasurable at first, the individual may not seek help. Families often notice the problem only after major disruption. The clinical challenge is to manage acute risk while supporting long-term mood stabilization.
Schizophrenia spectrum and other psychotic disorders
Psychotic disorders involve disruptions in perception, thought, and reality testing. Hallucinations, delusions, disorganized thinking, and negative symptoms are common features. Schizophrenia is one of the best-known disorders in this category.
Core symptoms include:
- hallucinations: sensory experiences without external stimulus, such as hearing voices,
- delusions: fixed false beliefs resistant to evidence,
- disorganized speech: incoherent or fragmented thinking,
- grossly disorganized or catatonic behaviour,
- negative symptoms: reduced emotional expression, avolition, alogia, or social withdrawal.
Schizophrenia does not mean “split personality”; that is a common misconception. Rather, it refers to disturbed integration of thought, perception, and behaviour. Causes are multi-factorial and may involve genetic risk, dopamine dysregulation, brain differences, prenatal complications, and stress. Treatment usually includes antipsychotic medication, psychosocial support, family intervention, and rehabilitation.
Obsessive-compulsive and related disorders
Obsessions are intrusive thoughts, images, or impulses that cause anxiety, while compulsions are repetitive behaviours or mental acts performed to reduce distress. OCD can become extremely time-consuming and impairing. A person may wash repeatedly, check locks, count, or seek reassurance because of fear that something terrible will happen.
Other related conditions include hoarding disorder and body-focused repetitive behaviours. The key issue is that the rituals do not provide lasting relief and often strengthen the cycle of anxiety. Exposure and response prevention is one of the most effective interventions.
Trauma- and stressor-related disorders
Trauma-related disorders arise after exposure to traumatic or highly stressful events. Post-traumatic stress disorder (PTSD) may follow assault, accidents, war, violence, or other terrifying experiences. Symptoms include:
- intrusive memories or flashbacks,
- avoidance of reminders,
- negative changes in mood and cognition,
- and heightened arousal.
In contexts with high community violence, trauma can become chronic and cumulative rather than a single-event experience. South African students should pay close attention to the link between trauma exposure, interpersonal violence, and later emotional difficulties. Treatment often includes trauma-focused psychotherapy, stabilization, and support for safety and functioning.
Substance-related and addictive disorders
Substance-related disorders involve harmful use of alcohol, drugs, or other substances that leads to impairment or distress. Dependence may include tolerance, withdrawal, craving, loss of control, and continued use despite harm. Addiction affects brain reward systems, decision-making, and behaviour.
Substance misuse can both cause and worsen mental health problems. It may be used as self-medication for anxiety, trauma, or depression, but it often intensifies symptoms over time. Effective treatment may require detoxification, psychosocial rehabilitation, relapse prevention, and support groups.
Personality disorders
Personality disorders are enduring patterns of inner experience and behaviour that deviate from cultural expectations and lead to distress or impairment. These patterns are typically inflexible, stable over time, and evident across situations.
Broadly, personality disorders are often discussed in clusters:
- Cluster A: odd or eccentric patterns
- Cluster B: dramatic, emotional, or erratic patterns
- Cluster C: anxious or fearful patterns
Examples include paranoid, schizoid, antisocial, borderline, histrionic, narcissistic, avoidant, dependent, and obsessive-compulsive personality styles. These conditions are complex because they involve identity, relationships, impulse control, and emotional regulation. Treatment is usually long-term and often includes psychotherapy rather than medication alone.
A concise comparison table
| Disorder group | Core features | Common risks | Typical treatment focus |
|---|---|---|---|
| Anxiety disorders | Fear, worry, avoidance, arousal | Panic, functional impairment, avoidance | CBT, exposure, relaxation, medication |
| Mood disorders | Depression, mania, mood swings | Suicide, relapse, impairment | Psychotherapy, medication, monitoring |
| Psychotic disorders | Delusions, hallucinations, disorganization | Self-neglect, risk, social decline | Antipsychotics, support, rehabilitation |
| OCD-related disorders | Obsessions and compulsions | Time loss, distress, avoidance | ERP, CBT, medication |
| Trauma-related disorders | Intrusions, avoidance, hyperarousal | Emotional numbing, sleep issues, dissociation | Trauma-focused therapy, stabilization |
| Substance-related disorders | Harmful use and dependence | Health damage, relapse, social problems | Detox, counselling, relapse prevention |
| Personality disorders | Enduring maladaptive patterns | Relationship conflict, instability | Long-term psychotherapy |
Why this section matters for exams
Exams often ask students to compare disorders, identify symptoms from case vignettes, or distinguish one disorder from another. Strong answers should not merely list symptoms. They should explain how the symptoms function, what the risks are, and why the disorder matters clinically. Use concrete language and avoid vague statements like “the person is not normal.” Instead, explain impairment, distress, persistence, and context.
5. Treatment, Prevention, Ethics, and South African Context
Principles of treatment
Treatment in mental health is not limited to medication or counselling. Effective intervention depends on matching the method to the problem, the severity of symptoms, the client’s preferences, and the resources available. Broadly, interventions include:
- biological treatments such as medication,
- psychological treatments such as psychotherapy,
- social interventions such as family support, school-based help, and community care,
- and rehabilitative services aimed at restoring function.
Good treatment is collaborative. Clients are more likely to improve when they understand the process and participate actively. Even when symptoms are severe, respect and partnership matter.
Psychotherapy approaches
Cognitive-behavioural therapy
CBT is among the most widely used and researched treatments. It helps clients identify unhelpful thoughts, test beliefs, and change patterns of behaviour. For depression, CBT may target negative automatic thoughts and behavioural withdrawal. For anxiety, it often includes exposure, relaxation, and cognitive restructuring.
CBT is structured, time-limited, and practical. It is especially effective when symptoms are linked to specific thought patterns and avoidance habits. However, it may not be sufficient on its own for severe trauma, complex personality problems, or major social adversity.
Psychodynamic therapy
Psychodynamic therapy explores unresolved conflict, relationship patterns, and unconscious themes. It can help clients understand recurring interpersonal difficulties and emotional blind spots. It tends to be less brief than CBT and may be valuable when symptoms relate to longstanding relational patterns.
Humanistic and person-centred therapy
Person-centred therapy emphasizes empathy, genuineness, and unconditional positive regard. It is particularly useful when shame, low self-worth, or emotional invalidation are central concerns. The therapeutic relationship itself becomes part of the healing process.
Family and systems approaches
Mental health difficulties often affect and are affected by families. Family therapy is useful for adolescent problems, psychosis, substance use, and chronic conflict. Systems approaches look at interaction patterns rather than isolating one “problem person.” This is important because family responses can either maintain symptoms or support recovery.
Medication and biological intervention
Medication can be life-changing for many people with severe mental disorders. Antidepressants, antipsychotics, mood stabilizers, anxiolytics, and stimulants may be prescribed depending on the condition. Medication is not a cure for every problem, but it can reduce symptoms enough for the person to engage in psychotherapy and daily functioning.
Medication decisions should consider:
- symptom severity,
- side effects,
- adherence,
- comorbid conditions,
- and the person’s broader circumstances.
Biological treatments are most effective when combined with psychological and social support. A person with bipolar disorder, for instance, may need mood stabilizers, psychoeducation, sleep regulation, and family involvement.
Prevention and promotion
Mental health care should not focus only on crisis management. Prevention works at multiple levels.
-
Primary prevention
Preventing disorders before they develop by reducing risk factors and building resilience. Examples include anti-bullying programmes, parenting support, and violence prevention. -
Secondary prevention
Early identification and treatment to stop problems from worsening. Screening and early intervention for depression, substance misuse, and psychosis are important examples. -
Tertiary prevention
Reducing disability and relapse after a disorder has already developed. Rehabilitation, supported employment, and community reintegration are key here.
Prevention matters because many people delay treatment due to stigma, cost, or lack of access. Early support often leads to better outcomes and lower long-term burden.
Ethical issues in mental health practice
Ethical practice is essential in all mental health settings. Core principles include:
- autonomy: respecting a person’s right to make informed choices,
- beneficence: acting in the person’s best interests,
- nonmaleficence: avoiding harm,
- justice: fair access to care,
- fidelity: maintaining trust and professional responsibility,
- confidentiality: protecting private information.
Ethical dilemmas are common. A client may refuse treatment despite serious risk. A minor may disclose abuse. A suicidal person may require urgent action that overrides ordinary confidentiality. Good practice requires balancing ethical principles carefully and documenting decisions responsibly.
Stigma and discrimination
Stigma remains one of the biggest barriers to care. People with mental illness may be seen as dangerous, weak, unpredictable, or hopeless. This leads to shame, delayed help-seeking, social exclusion, and discrimination in work or education. Self-stigma can be just as damaging as public stigma because the person internalizes negative beliefs and loses confidence.
Reducing stigma requires education, contact with recovered individuals, respectful language, and public awareness. Exam answers should emphasize that stigma is not just an attitude problem; it is a structural barrier that affects treatment outcomes and quality of life.
South African context
Mental health in South Africa is shaped by a unique combination of historical, social, and economic factors. High levels of unemployment, inequality, gender-based violence, trauma exposure, and resource shortages place heavy pressure on individuals and families. At the same time, the country has strong community traditions, faith-based support systems, and growing advocacy for mental health rights.
Important contextual considerations include:
- unequal access to psychiatric services in urban and rural areas,
- language and cultural diversity,
- stigma in communities and families,
- the impact of poverty on treatment adherence,
- and the need for integrated care in public health settings.
Students should also understand that mental health services may be delivered by multidisciplinary teams including psychologists, psychiatrists, psychiatric nurses, social workers, counsellors, and community health workers. Collaboration is essential because no single profession can meet all needs.
Exam technique for PYC3702
High-scoring answers usually do more than repeat definitions. They show analysis, application, and comparison. A strong essay often includes:
- a clear definition of the concept,
- an explanation of theoretical viewpoints,
- an applied example,
- a comparison of strengths and limitations,
- and a brief conclusion that links the idea to practice or context.
For case-based questions, follow a methodical process:
- identify the main symptoms,
- match them to a likely disorder,
- explain why the diagnosis fits,
- mention possible causes,
- and suggest appropriate intervention.
For example, if a case describes sleep loss, elevated mood, pressured speech, grandiosity, and risky spending, the best answer would likely identify mania or bipolar disorder, explain the signs, and mention mood stabilisation and clinical assessment. If a case describes intrusive thoughts, handwashing, and repeated checking, OCD is more likely.
Final revision points
The most important ideas in this study guide are the following:
- Abnormal behaviour must be understood in context.
- Mental health problems are multi-causal, not caused by one factor alone.
- The major approaches — biological, psychodynamic, behavioural, cognitive, humanistic, and sociocultural — each explain different parts of the picture.
- Classification systems help organise diagnosis, but they are not perfect.
- Major disorders include anxiety disorders, mood disorders, psychotic disorders, trauma-related disorders, substance-related disorders, personality disorders, and OCD-related conditions.
- Effective treatment is usually integrated, combining psychological, biological, and social support.
- Ethics, stigma, and cultural competence are central to responsible mental health care.
- South African realities such as trauma, poverty, and unequal access to care must always be considered.
A well-prepared PYC3702 student should be able to define abnormality, compare theoretical perspectives, identify symptoms in case studies, explain diagnostic issues, and discuss treatment and social context with confidence. The strongest exam performance comes from answers that are clear, organized, and applied rather than memorized in a superficial way.
