Diagnose the pattern, then measure kleptomania symptoms with K-SAS
| Syllabus disorder | Pattern to establish | Distinguishing evidence |
|---|---|---|
| Kleptomania | Recurrent failure to resist impulses to steal objects not needed for personal use or monetary value | Rising tension before stealing and pleasure, gratification or relief during/after; consider alternative motives and explanations |
| Pyromania | Recurrent failure to control strong fire-setting impulses, with multiple acts or attempts | No apparent external motive; fascination/preoccupation with fire, arousal before and pleasure/relief during or after; exclude another disorder or intoxication |
| Gambling disorder | Persistent online/offline pattern with impaired control, increasing priority and continuation/escalation despite harm | Extended course, which may be continuous or recurrent, plus significant distress or impairment in important life areas |
Application rule: quote the exact criterion, identify matching case evidence, then explain the link. Also test disconfirming evidence. One fire with revenge motive may fail pyromania criteria; gambling frequency alone lacks impaired control, priority, persistence and harm. Shame, illegality, mixed motives and incomplete disclosure can reduce diagnostic validity.
| K-SAS domain over the past week | What its closed, scaled prompts ask |
|---|---|
| Urges | Average strength, frequency, hours preoccupied and ability to control |
| Thoughts | Frequency, hours thinking and ability to control |
| Before/during theft | Anticipatory tension/excitement and excitement/pleasure on a successful theft, including estimated experience if no theft occurred |
| Consequences | Emotional distress and personal relationship, financial, legal, work or health trouble |
| Behaviour | Number of thefts |
The production mark-scheme evidence lists 12 prompts. Their standardised quantitative responses allow comparison and monitoring, while optional explanation/interview data can add qualitative meaning.
| Lens | Evaluation |
|---|---|
| Nomothetic–idiographic | Same prompts support comparison, but fixed categories can miss a person's motive, context and lived meaning |
| Objective–subjective | Numerical scoring is standardised; the underlying memory, estimate and disclosure remain subjective |
| Validity | One-week focus limits vague lifetime recall, but social desirability, shame and illegal behaviour may suppress reports |
| Method choice | Interview/questionnaire are self-report; ethical observation or case-study evidence can triangulate without deliberately enabling harm |
K-SAS measures kleptomania symptom experience and change; it is not a pyromania scale and does not independently diagnose. This card is curriculum teaching, not a self-diagnosis tool. Real assessment and risk management require qualified professionals.
Reward biology, reinforcement and feeling-state memory explain repeated impulses at different levels
| Explanation | Mechanism | Applied example and boundary |
|---|---|---|
| Biological: dopamine | Reward-related dopamine activity contributes to motivation, anticipation and learning; cues and rewarding outcomes can strengthen wanting and repetition | A gambling cue may acquire motivational salience, but dopamine involvement is probabilistic and not a complete single cause |
| Behavioural: positive reinforcement | A consequence added after behaviour increases its future frequency | Money can reinforce gambling; thrill/relief can reinforce stealing or fire setting; intermittent wins maintain gambling because the next response might be rewarded |
| Cognitive: Miller's feeling-state theory | A triggering behaviour becomes linked to intense positive emotion, thoughts and physiological arousal, forming a state-dependent feeling-state memory | The person repeats the behaviour to recreate euphoria/power despite harm; the integrated remembered state, not emotion alone, drives compulsive repetition |
Common cycle: cue or opportunity → anticipation/urge → impulsive behaviour → reward, thrill or relief → stronger cue-behaviour association and remembered feeling-state → greater repetition risk. The three explanations illuminate different links rather than being mutually exclusive.
| Debate | Comparison |
|---|---|
| Nature–nurture | Dopamine emphasises biological processes; reinforcement and feeling-state links are largely acquired through experience; interaction is plausible |
| Individual–situational | Cognitive feeling-states are person-specific; reinforcement depends on environmental schedules/opportunities; individuals may also select situations |
| Reductionism–holism | Dopamine and reinforcement isolate testable parts; Miller is more holistic because emotion, cognition, physiology and memory operate together, yet still omits some social/biological factors |
| Determinism–free will | Reward histories and neural processes constrain behaviour, but cue avoidance, environmental change and therapy preserve degrees of agency |
| Application/generalisation | Each model suggests intervention targets, but one case or one disorder cannot establish the theory for every impulse-control disorder |
Evidence could combine structured observation of frequency, a qualified interview about feeling-states, and a questionnaire with standardised scaled items. Observation improves behavioural objectivity but cannot directly reveal private thoughts; self-report accesses the feeling-state but is vulnerable to interpretation and disclosure bias.
Positive reinforcement means a rewarding consequence increases behaviour; it does not mean praise and is not punishment. Miller's feeling-state contains emotions, thoughts and physiological arousal. Dopamine participation does not mean a person has no choice or that one chemical fully explains the disorder.
Treatments target reward, imagined aversion or relaxed non-enactment
| Treatment | Target and procedure | Expected change |
|---|---|---|
| Opiate-antagonist drug/placebo trials | Pharmacologically reduce opioid-mediated reward/urge processes; compare active drug with inert placebo under controlled conditions | Test whether urges/behaviour improve beyond expectancy and time |
| Covert sensitisation | Rehearse the impulse sequence in imagination, pair it with vivid aversive consequences, then end aversion when the person rejects/leaves the act | The cue/act becomes less attractive through imagined aversive conditioning |
| Imaginal desensitisation | Learn progressive muscle relaxation, visualise graded cue/urge situations, imagine not acting or leaving while staying relaxed, and practise between sessions | Lower arousal and weaken the urge-behaviour/positive-feeling connection |
| Grant et al. (2008): verified production evidence |
|---|
| Two gambling-disorder drug-versus-placebo trials used nalmefene and naltrexone. |
| The two trial durations were 16 weeks and 18 weeks; the available exact question evidence does not require assigning a duration to a named drug. |
| Research ran across the University of Minnesota and outpatient psychiatric treatment centres. Multiple locations may broaden participant/settings and generalisability, but site differences and self-selection can also create participant or procedural variation. |
| Placebo comparison helps separate pharmacological change from expectation; group findings still do not guarantee an individual response. |
Glover (1985) covert sensitisation: a participant imagined increasing nausea while approaching an intended supermarket theft, vomiting when lifting the item and attracting other shoppers' attention. The unpleasant imagery stopped when she replaced the item, turned away and left. The aversive event is imagined—this is not relaxation-based desensitisation.
Blaszczynski and Nower (2003) syllabus treatment: progressive relaxation is paired with imagined gambling/impulse cues and successful non-enactment. Applied to pyromania, the learner should describe relaxation, visualising planning/approaching the fire-setting situation, imagining leaving without acting while relaxed, repeated practice, and reduced anticipatory arousal—not nausea or punishment imagery.
| Lens | Evaluation |
|---|---|
| Application | Drugs are standardised; imagery techniques can be practised when safe and may transfer across situations |
| Reductionism–holism | Drug treatment reduces the problem to reward biology; CBT procedures include cues, thoughts, arousal and behaviour but may omit wider context |
| Idiographic–nomothetic | Standard protocols allow replication; imagery must be personalised to triggers and tolerability |
| Evidence/generalisation | Controlled/placebo and multisite features strengthen inference; case evidence and disorder/site differences limit population claims |
| Ethics/suitability | Monitor adverse effects, informed consent, distressing imagery, comorbidity and risk; no technique should recreate illegal or dangerous behaviour |
Covert sensitisation adds imagined aversion; imaginal desensitisation adds relaxation and successful non-enactment. Neither is simply imagining the behaviour. Drug/placebo evidence tests average causal effects under study conditions and is not treatment advice or proof of a universal cure.
