Clinical Psychology and Organizational Behaviour: Disorders, Assessment, Psychotherapies, Culture, Decisions and Leadership
2. Assessment, diagnosis and classification: DSM and other tools
Classification gives clinicians a common language, guides treatment and research, and informs prognosis. Two systems dominate. The DSM-5-TR (the 2022 text revision of the 2013 DSM-5) is published by the American Psychiatric Association; the ICD-11 is published by the World Health Organization and is the system used for international health statistics. A major change in DSM-5 was dropping DSM-IV's multiaxial (five-axis) system: diagnoses are now listed together with separate notes on psychosocial and contextual factors. Classification is still largely categorical (a disorder is present or absent), though dimensional severity ratings have been added.
A sound classification must meet two standards: reliability (do independent clinicians agree on the diagnosis — inter-rater agreement) and validity (does the category predict course and respond to the right treatment). The risks are over-diagnosis, cultural bias and labelling — once a label is attached it colours later observation, as Rosenhan's 1973 study "On being sane in insane places" is commonly read to show.
- Clinical interview (structured, semi-structured or unstructured) and the Mental Status Examination (MSE) — appearance, mood, thought, perception, cognition and insight.
- Projective tests — the Rorschach Inkblot Test and the Thematic Apperception Test (TAT); ambiguous stimuli draw out inner states, rich in material but lower in reliability.
- Objective self-report inventories — the MMPI, with fixed items scored against norms; and intelligence, neuropsychological and behavioural-observation measures.
| Category | Core feature | Example |
|---|---|---|
| Anxiety disorders | Excessive fear and anxiety out of proportion to the situation | Specific phobia, panic disorder |
| Depressive and bipolar disorders | Disturbed mood — persistent lowness or swings between lows and highs | Major depressive disorder, bipolar disorder |
| Schizophrenia spectrum | Psychosis — hallucinations, delusions, disorganized thought | Schizophrenia |
| Obsessive-compulsive and related | Intrusive thoughts and repetitive acts done to relieve them | Obsessive-compulsive disorder (OCD) |
| Trauma- and stressor-related | A reaction that follows exposure to a traumatic event | Post-traumatic stress disorder (PTSD) |
| Neurodevelopmental disorders | Early-onset deficits in development and functioning | Autism spectrum disorder, ADHD |
3. Psychotherapies I: psychodynamic and phenomenological/experiential
Psychodynamic therapy, founded by Sigmund Freud, aims at insight — making unconscious conflict conscious. Its techniques are free association, dream interpretation, and the analysis of transference (feelings the patient displaces onto the analyst) and resistance; the analyst offers interpretations, and change comes through "working through". Later brief psychodynamic therapies keep the ideas but shorten the course.
Phenomenological/experiential therapies focus on present experience, subjective meaning and growth rather than on hidden conflict.
- Client-centred (person-centred) therapy — Carl Rogers: non-directive, it works through three core conditions the therapist provides — congruence (genuineness), unconditional positive regard and empathic understanding — which free the client's own actualizing tendency.
- Gestalt therapy — Fritz Perls: awareness in the here-and-now and owning one's experience, using devices such as the empty-chair dialogue.
- Existential therapy, such as Viktor Frankl's logotherapy, confronts freedom, responsibility, mortality and the search for meaning.
4. Psychotherapies II: behaviour, cognitive, REBT, meditation and biological
- Behaviour therapy applies learning principles. Systematic desensitization (Joseph Wolpe) rests on reciprocal inhibition: deep relaxation is paired with a graded hierarchy of feared situations so that relaxation inhibits anxiety. Exposure and flooding confront the feared stimulus directly; aversion therapy pairs an unwanted behaviour with an unpleasant stimulus; token economies and modelling use operant and observational learning.
- Cognitive therapy (Aaron Beck) finds automatic negative thoughts and cognitive distortions and tests them against evidence (cognitive restructuring); in depression the cognitive triad is the negative view of the self, the world and the future.
- REBT (Albert Ellis) uses the ABC(DE) model: an Activating event does not cause the Consequence; irrational Beliefs do, and the therapist actively Disputes them to reach a new Effect. Beck's and Ellis's approaches both feed into modern CBT.
Meditation, with roots in Buddhist vipassanā and yogic traditions, is used therapeutically as concentrative or mindfulness practice: Mindfulness-Based Stress Reduction (Jon Kabat-Zinn) and mindfulness-based cognitive therapy reduce stress and relapse, and Benson's "relaxation response" lowers arousal. Biological (somatic) therapy acts on the nervous system: psychotropic drugs — antidepressants (including SSRIs), antipsychotics, anxiolytics, and lithium as a mood stabiliser in bipolar disorder — plus electroconvulsive therapy (ECT) for severe, treatment-resistant depression and newer rTMS; historical psychosurgery is now rare.
5. Organizational behaviour: diversity, culture and decision making
Organizational behaviour (OB) studies people in organizations at three levels — individual, group and organizational. Diversity is of two kinds: surface-level (demographic) differences in age, sex, ethnicity or ability, and deep-level differences in values, personality and attitudes; well-managed cultural diversity improves problem-solving, while mismanaged diversity raises conflict. Hofstede's cultural dimensions — power distance, individualism versus collectivism, uncertainty avoidance, masculinity versus femininity, long-term orientation and indulgence — describe national-culture differences that shape behaviour at work.
Organizational culture is the shared values and assumptions that guide behaviour. Edgar Schein's three levels run from visible artifacts (dress, layout, rituals), through espoused values (stated goals and strategy), to basic underlying assumptions — the taken-for-granted beliefs that form culture's true core. A strong culture aligns behaviour but can resist change; subcultures coexist with the dominant culture.
In decision making, the rational model assumes full information and optimizing, but Herbert Simon's bounded rationality says real managers satisfice — they accept the first "good enough" option. Judgement is bent by heuristics and biases (anchoring, availability, confirmation) and by escalation of commitment to a failing course. In groups, groupthink (Irving Janis) — the drive for consensus suppressing dissent — degrades decisions; a devil's advocate and structured methods (brainstorming, the nominal group technique, Delphi) are the standard counters.
6. Power and politics, leadership, positive OB and performance management
French and Raven name five bases of power: legitimate (from position), reward, coercive, expert (from knowledge) and referent (from identification and liking). Authority is legitimate power; influence is power in use; organizational politics is the use of power outside formal channels to pursue one's interests.
| Family | Core claim | Key examples |
|---|---|---|
| Trait | Leaders are marked by stable inborn qualities | Great-man accounts of leadership |
| Behavioural | What leaders do matters more than what they are | Ohio State (initiating structure, consideration), Michigan, Blake and Mouton grid |
| Contingency | The best style depends on the situation | Fiedler (LPC and favourableness), House path-goal, Hersey-Blanchard situational |
| New leadership | Leaders transform and inspire beyond exchange | Transactional versus transformational (Burns, Bass), charismatic, servant (Greenleaf) |
Lewin's classic styles are autocratic, democratic and laissez-faire. Transactional leadership exchanges rewards for performance; transformational leadership (Bass) lifts followers beyond self-interest through idealized influence, inspirational motivation, intellectual stimulation and individualized consideration. Positive organizational behaviour (Fred Luthans) studies measurable, developable strengths; psychological capital (PsyCap) combines hope, self-efficacy, resilience and optimism (the HERO set).
Key takeaways
- Abnormality is weighed by the four Ds (deviance, distress, dysfunction, danger) and modelled biologically, psychodynamically, behaviourally, cognitively, humanistically or socioculturally; the diathesis-stress and biopsychosocial models integrate a predisposing vulnerability with stress and context.
- DSM-5-TR (American Psychiatric Association, 2022) and ICD-11 (WHO) classify disorders; DSM-5 dropped DSM-IV's multiaxial system; a good classification needs reliability and validity. Assessment uses the interview and MSE, projective tests (Rorschach, TAT), objective inventories (MMPI) and neuropsychological measures.
- Psychodynamic therapy (Freud) seeks insight via free association, dreams, transference and resistance; experiential therapies centre present experience — Rogers's client-centred therapy (congruence, unconditional positive regard, empathy), Perls's Gestalt and Frankl's existential logotherapy.
- Behaviour therapy uses conditioning — Wolpe's systematic desensitization (reciprocal inhibition), exposure, aversion, token economies; cognitive therapy (Beck, cognitive triad) and REBT (Ellis, ABC) restructure thinking; meditation (MBSR) and biological therapy (drugs, lithium, ECT, rTMS) complete the range.
- Organizational behaviour spans individual, group and organizational levels; diversity is surface versus deep-level; Schein's culture has artifacts, espoused values and basic assumptions; decisions are bounded-rational (Simon, satisficing) and marred by biases, escalation and groupthink (Janis).
- French and Raven name five power bases (legitimate, reward, coercive, expert, referent); leadership theory runs trait, behavioural, contingency (Fiedler, path-goal, situational), to transformational (Bass); positive OB and PsyCap (Luthans, HERO) stress strengths; performance management favours reinforcement over punishment (Skinner).
Practice questions (17)
Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
A clinician holds that a disorder develops only when an inherited vulnerability is combined with enough life stress to trigger it. In this diathesis-stress account, the 'diathesis' refers to:
Show answer
Answer: A — A pre-existing predisposition or vulnerability that makes the disorder more likely
In the diathesis-stress model the diathesis is the predisposing vulnerability (genetic, biological or psychological), and stress is the trigger; a disorder appears only when both are present. The tempting wrong choice names the stress — the precipitating life event — which is the second term of the model, not the diathesis. A therapeutic relationship and an unconscious conflict belong to other frameworks entirely.The Diagnostic and Statistical Manual of Mental Disorders (DSM-5 and DSM-5-TR) is published by:
Show answer
Answer: C — The American Psychiatric Association, the professional body representing psychiatrists
The DSM is produced by the American Psychiatric Association, a body of psychiatrists. The most tempting error is the American Psychological Association — a separate organisation that happens to share the initials. The WHO publishes the ICD, not the DSM, and the British Psychological Society publishes neither.Which statement correctly describes a change that DSM-5 introduced relative to DSM-IV?
Show answer
Answer: B — It discontinued the multiaxial (five-axis) diagnostic system that DSM-IV had used
DSM-5 removed DSM-IV's five-axis multiaxial format, folding the information into a single list of diagnoses with separate notes on psychosocial and contextual factors. DSM-5 did not become purely dimensional — it stayed largely categorical while adding some dimensional severity ratings — so that choice overstates the change. Authorship stayed with the American Psychiatric Association, and criteria sets were kept, so both of those are false.Which of the following are projective techniques of personality assessment?
Show answer
Answer: A — The Rorschach Inkblot Test; B — The Thematic Apperception Test (TAT)
Projective techniques present ambiguous stimuli — inkblots in the Rorschach, ambiguous scenes in the TAT — and infer inner states from the responses. The MMPI is an objective, fixed-item self-report inventory, and the WAIS is a standardized intelligence test, so neither is projective and both are excluded.Congruence (genuineness), unconditional positive regard and empathic understanding are the three therapist-provided conditions at the centre of:
Show answer
Answer: D — Carl Rogers's client-centred (person-centred) therapy
These three 'core conditions' are the heart of Carl Rogers's client-centred therapy, which is non-directive and trusts the client's own actualizing tendency. Wolpe's method uses relaxation and exposure hierarchies, Beck tests automatic thoughts against evidence, and Ellis disputes irrational beliefs — none is built on the core conditions.Systematic desensitization, developed by Joseph Wolpe, reduces a phobia principally by:
Show answer
Answer: A — Pairing deep relaxation with a graded hierarchy of feared situations so that relaxation inhibits the anxiety
Systematic desensitization rests on reciprocal inhibition: a response incompatible with anxiety — deep muscle relaxation — is paired with feared items presented in a graded hierarchy from mild to intense, so anxiety is progressively counter-conditioned. Confronting the worst item at once is flooding, a different technique; interpreting transference is psychodynamic; disputing irrational beliefs is REBT.Both Aaron Beck's cognitive therapy and Albert Ellis's REBT target maladaptive thinking. Which statement best captures the distinction usually drawn between them?
Show answer
Answer: C — Beck collaboratively tests automatic thoughts as hypotheses against evidence, whereas Ellis more forcefully disputes irrational core beliefs
The standard contrast is one of style and emphasis: Beck's cognitive therapy is collaborative empiricism — client and therapist treat negative automatic thoughts as hypotheses to be tested against evidence — while Ellis's REBT actively and directly disputes irrational beliefs in the ABC framework. Free association and dream analysis are psychodynamic; extinction and unconscious conflict belong to behavioural and psychodynamic models; and neither therapy is restricted by the client's age or setting.Mindfulness-Based Stress Reduction (MBSR), a structured programme using mindfulness meditation to manage stress and pain, is most closely associated with:
Show answer
Answer: B — Jon Kabat-Zinn
Jon Kabat-Zinn developed the Mindfulness-Based Stress Reduction programme, from which mindfulness-based cognitive therapy later grew. Beck founded cognitive therapy, Wolpe devised systematic desensitization, and Perls created Gestalt therapy, so none of those three is the answer.Which of the following are biological (somatic) therapies for psychological disorders?
Show answer
Answer: A — Electroconvulsive therapy (ECT) for severe, treatment-resistant depression; B — Lithium used as a mood stabiliser in bipolar disorder; D — Repetitive transcranial magnetic stimulation (rTMS)
ECT, lithium (a psychotropic mood stabiliser) and rTMS all act directly on the nervous system and are biological (somatic) treatments. Systematic desensitization is a behaviour therapy built on learning principles, not a biological one, so it is the only option excluded from the set.In Edgar Schein's model of organizational culture, the deepest and least visible level — the taken-for-granted beliefs members are often unaware of — is:
Show answer
Answer: D — The basic underlying assumptions about how the world and the organization work
Schein's three levels run from visible artifacts, through espoused values, to the basic underlying assumptions — the unconscious, taken-for-granted beliefs that form culture's true core. Artifacts are the most visible layer and espoused values the middle layer, so naming either mistakes a surface level for the deepest; a mission statement is a particular espoused value, not the deepest level.A manager, lacking the time and information to evaluate every option, picks the first alternative that is 'good enough' rather than the mathematically best one. This behaviour is captured by:
Show answer
Answer: A — Herbert Simon's bounded rationality and satisficing
Choosing the first acceptable option instead of optimising is 'satisficing', the core of Herbert Simon's bounded rationality: real decision makers are limited by information and cognition. The classical rational model assumes exactly the optimisation the manager does not attempt; groupthink concerns group consensus pressure; and expectancy theory explains motivation, not this decision shortcut.A cohesive committee, eager to agree, convinces itself that everyone supports the plan, and members who privately doubt it keep silent. In Irving Janis's analysis, this illustrates which symptom of groupthink?
Show answer
Answer: C — An illusion of unanimity reinforced by self-censorship of doubts
Janis lists the illusion of unanimity and self-censorship among the symptoms of groupthink: members assume silence means consent and suppress their own doubts. A devil's advocate, a broad search of alternatives and independent subgroups are remedies that counter groupthink, not symptoms of it, so each of those is wrong.Which of the following are cognitive biases or traps that can distort decision making in organizations?
Show answer
Answer: A — Anchoring on an initial figure when making later estimates; B — Confirmation bias — seeking mainly evidence that supports a favoured option; C — Escalation of commitment to a visibly failing course of action
Anchoring, confirmation bias and escalation of commitment are all well-documented distortions of organizational judgement. Reciprocal inhibition is the learning principle behind Wolpe's systematic desensitization — a therapy mechanism, not a decision bias — so it is the only option that does not belong.In French and Raven's framework, the power a manager holds simply because of the formal position she occupies in the hierarchy is:
Show answer
Answer: B — Legitimate power, grounded in the formal right to direct that comes with the office
Legitimate power flows from the formal position itself — the right to direct that comes with the office. Expert power rests on knowledge, referent power on identification and liking, and coercive power on the ability to punish; each is a different base among French and Raven's five, so none fits a power that comes purely from rank.Fiedler's contingency model of leadership holds that leadership effectiveness depends on:
Show answer
Answer: D — The match between the leader's style, indexed by the least-preferred-coworker score, and the favourableness of the situation
Fiedler indexes a leader's orientation with the least-preferred-coworker (LPC) scale and argues that task-oriented and relationship-oriented leaders each perform best in situations of differing favourableness — effectiveness is the fit between the relatively fixed style and the situation. Adapting to follower readiness is Hersey and Blanchard's situational model; clearing the path to goals is House's path-goal theory; inborn traits are the trait approach Fiedler moved beyond.According to Bernard Bass, which of the following are components of transformational leadership?
Show answer
Answer: A — Idealized influence — serving as a role model whom followers admire and trust; B — Inspirational motivation — articulating an appealing and meaningful vision; C — Intellectual stimulation — encouraging followers to question assumptions and innovate
Bass's transformational leadership has four components — idealized influence, inspirational motivation, intellectual stimulation and individualized consideration. Contingent reward belongs instead to transactional leadership, which exchanges rewards for performance, so it is the one option that does not fit the set.A supervisor cancels a disliked weekend reporting duty for team members as soon as they begin filing their logs on time, and timely filing then increases. In operant terms, the removal of the disliked duty is:
Show answer
Answer: A — Negative reinforcement, because removing an unpleasant consequence strengthens the behaviour
Removing an aversive stimulus (the disliked duty) to make a behaviour more frequent is negative reinforcement — 'negative' means something is taken away, 'reinforcement' means the behaviour increases. It is not punishment, which decreases behaviour; not positive reinforcement, which adds a pleasant stimulus rather than removing an unpleasant one; and not extinction, where reinforcement simply stops and the behaviour fades.
