Original StudyForA educational content mapped to Cambridge 2028–2030 Version 1 and WHO ICD-11 CDDR. The Cambridge option heading groups gambling disorder with impulse-control topics, while ICD-11 classifies gambling disorder under addictive behaviours. This summary is not clinical advice, a screening or diagnostic tool, Cambridge material, an official mark scheme or an awarded grade. Do not reproduce or use K-SAS items to assess a learner. Human subject-expert review and full timed-paper grading remain pending.
Before you begin
- This lesson covers 9990 Clinical Psychology topic 1.3.1. It teaches classification and questionnaire evaluation; it does not diagnose a person or assess criminal responsibility.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which statement correctly distinguishes gambling disorder in Cambridge's topic map and ICD-11?
What you will learn
- Describe the ICD-11 features of kleptomania and pyromania and distinguish a disorder from a single act
- Describe the ICD-11 pattern of gambling disorder and its functional-impact and duration requirements
- Explain the scope and limits of the Kleptomania Symptom Assessment Scale (K-SAS)
- Evaluate these criteria and measures using subjective and objective evidence, questionnaires and individual case context
Start with classification, not a label for a person
Cambridge 9990 groups kleptomania, pyromania and gambling disorder in its 1.3 impulse-control section. ICD-11 classifies pyromania (6C70) and kleptomania (6C71) as impulse-control disorders, while gambling disorder (6C50) is placed under disorders due to addictive behaviours. Follow Cambridge's topic grouping for the course, but name the ICD-11 distinction accurately.
A diagnostic classification describes a sustained pattern and the context needed for professional assessment. An isolated act, a questionnaire response, a police record or a learner's fictional answer cannot establish a diagnosis. The descriptions below are for syllabus study only; do not use them to diagnose yourself or another person.
ICD-11 describes pyromania and kleptomania as recurrent patterns
Pyromania involves recurrent difficulty controlling strong impulses to set fires, resulting in multiple acts or attempts without an apparent motive such as financial gain, revenge or sabotage. The person has a persistent fascination or preoccupation with fire, increasing tension or arousal beforehand, and pleasure, relief or gratification during or after the act. A clinician must consider whether another mental or behavioural disorder, intellectual impairment or substance intoxication better explains the behaviour.
Kleptomania involves recurrent difficulty controlling strong impulses to steal objects without an apparent motive such as personal use or monetary gain. Tension or arousal increases before the theft, followed by pleasure, relief or gratification during or immediately after it. The behaviour must not be better explained by intellectual impairment, another mental or behavioural disorder or substance intoxication; theft occurring within conduct-dissocial disorder or a manic episode should not be diagnosed separately as kleptomania.
These descriptions do not make deliberate, planned theft for money or fire-setting for revenge equivalent to kleptomania or pyromania. Nor does one episode establish the repeated pattern. Naming a possible criterion is an analysis step, not a moral judgement or a diagnosis.
Gambling disorder has three central features and a functional threshold
ICD-11 gambling disorder can involve online or offline gambling. Its pattern includes impaired control over gambling, increasing priority given to gambling over other interests and daily activities, and continuation or escalation despite negative consequences. The pattern must cause significant distress or significant impairment in important areas of life.
The pattern may be continuous or episodic and recurrent. It is normally evident for at least 12 months, although the duration may be shorter when all diagnostic requirements are met and symptoms are severe. Gambling that creates harm can occur below the threshold for a disorder, so a learning example should distinguish harm, risk and a formal clinical diagnosis.
Unlike kleptomania and pyromania, ICD-11 classifies gambling disorder under addictive behaviours. This matters when comparing course headings with the classification system and when discussing what a measure or study actually assessed.
K-SAS is a symptom-severity questionnaire for kleptomania
The Kleptomania Symptom Assessment Scale (K-SAS) is an 11-item self-report measure about symptoms during the previous week. Its questions cover the severity, frequency, duration and control of stealing urges; related thoughts; excitement before and during stealing; subjective distress; and resulting problems. It measures a person's reported symptoms and impact, not every impulse-control disorder.
A 2020 Japanese validation study compared 22 people with kleptomania, 26 shoplifters and 47 healthy adults. The authors reported adequate reliability and validity indicators for that Japanese version, including internal consistency in their sample. The result is evidence about that translation and sample; it does not establish identical validity in every language, culture or setting.
A questionnaire can provide standardised, quantitative self-report that helps compare responses over time or between groups. It can miss context, rely on memory and be affected by interpretation, disclosure or translation. A K-SAS score alone is not an ICD-11 diagnosis, a lie detector or a complete account of a person; a qualified professional considers wider evidence and differential explanations.
Evaluate the evidence with the syllabus methods and debates
Questionnaires can turn subjective experiences into comparable scores, but the score is still based on what a person reports. Reliability asks whether measurement is consistent; validity asks whether it measures the intended construct in the people and language where it is used. A translated scale needs its own cultural and psychometric evaluation.
Nomothetic criteria help professionals communicate and compare patterns, while individual context can reveal motives or explanations a checklist misses. A strong answer combines standardised criteria with idiographic information rather than treating either as sufficient alone.
For an exam response, distinguish the diagnostic criteria from K-SAS measurement, identify what the evidence is about, and give a limitation tied to the sample, self-report or context. Avoid converting criminal or risky behaviour into a psychiatric label without the full professional assessment.

Pause and explain
What does a high K-SAS score establish by itself?
Worked example
A fictional report says someone stole a high-value item to sell it for rent money once. Does this information establish kleptomania? Explain what is missing.
Show the worked solution
- Compare the stated motive with the ICD-11 description, which refers to stealing without an apparent motive such as monetary gain.
- Check whether the report describes a recurrent pattern and the tension and relief features, rather than one act.
- State why the vignette cannot support a diagnosis and what wider assessment would be needed.
Answer No. The report gives an apparent financial motive and only one act, whereas the ICD-11 description concerns a recurrent pattern of stealing without an apparent motive, with tension beforehand and gratification or relief during or after. A fictional account omits wider history and differential explanations, so it cannot establish a diagnosis.

Test this topic →From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Compare three fictional descriptions: A steals once to sell an item for money; B repeatedly steals unwanted objects after mounting tension and later relief; C repeatedly gambles online, cannot limit it, puts it ahead of other activities and continues despite serious consequences. Identify what each description can and cannot support.
Give me a hint
Use motive and repetition for A and B; use the three gambling features and life impact for C.
Compare my reasoning
- A describes a single theft with a financial motive, which is unlike the recurrent no-apparent-motive pattern described for kleptomania; it does not establish a disorder.
- B resembles some features of the ICD-11 kleptomania description, but a short fictional report still omits full history and alternative explanations, so it cannot establish a diagnosis.
- C describes impaired control, increasing priority and continuation despite consequences with serious impact, which are central gambling-disorder features; duration and full assessment remain unstated.
A is a single financially motivated theft, not evidence of kleptomania. B includes a recurrent urge pattern and tension/relief that resembles the description, but a vignette cannot diagnose a real person. C includes the three central gambling features and significant impact, but the account omits duration and professional assessment. Analyse stated evidence without assigning a label.
Look for these in your work
- Motive distinguished
- Three gambling features applied
- Diagnostic limits stated
A school translates the K-SAS and gives it to students as a ‘kleptomania test’. Explain two problems and propose a more appropriate use of the measure.
Give me a hint
Distinguish reliability from validity and a symptom scale from a diagnostic assessment.
Compare my reasoning
- A translated scale may not preserve item meaning or measurement properties; reliability and validity need to be evaluated in the new language and population.
- The K-SAS is a self-report of recent kleptomania-related symptoms, not a diagnosis and not a tool to label students or assess every impulse-control disorder.
- If used in approved research with appropriate permissions, it could describe or compare symptom reports in the intended population, alongside suitable consent, confidentiality, other evidence and professional oversight.
The school cannot assume a translation is valid or use a self-report symptom scale as a diagnostic test for students. A culturally assessed K-SAS could support appropriate, ethically approved research about reported kleptomania symptoms, but it would need consent, privacy, relevant comparison measures and professional interpretation.
Look for these in your work
- Translation validity considered
- Self-report and diagnosis distinguished
- Ethical and appropriate use proposed
Plan a small, ethical study checking whether a translated K-SAS gives consistent responses and distinguishes a clinically assessed kleptomania group from a comparison group. Give a method, one validity check and two limits.
Give me a hint
Use independent professional assessment, consent and privacy safeguards; do not induce theft or recruit learners as a convenience sample.
Compare my reasoning
- Recruit consenting adults through an appropriate clinical service and a suitable comparison route; have qualified professionals assess participants independently of their K-SAS scores, and protect sensitive responses.
- Repeat the scale after a planned interval when clinically appropriate to examine test-retest consistency, and check whether translated items are understood as intended; compare score patterns with the independent assessment without treating the scale as the diagnosis.
- A small service-based sample may not generalise to other languages or contexts, and repeat scores can be influenced by memory, symptom change or response style. Participants must be able to decline or withdraw without affecting care.
A suitable validation study would use consenting adults, independent clinical assessment, a carefully reviewed translation and a planned repeat measurement. It could examine consistency and whether scores distinguish the intended groups, but a small clinical sample and response or language effects limit generalisation. Participation must be voluntary, confidential and separate from access to care.
Look for these in your work
- Independent comparison defined
- Reliability and validity checks specified
- Consent, withdrawal and generalisation limits included
Common mistakes
- Treating Cambridge's 1.3 course grouping as if ICD-11 places gambling disorder under impulse-control disorders
- Diagnosing kleptomania or pyromania from a single act or a person's score
- Confusing motivated theft for gain or revenge with the ICD-11 descriptions
- Forgetting persistent fire fascination in the pyromania description
- Omitting impaired control, priority, continued behaviour and significant impact when describing gambling disorder
- Treating gambling-related harm below the diagnostic threshold as proof of a disorder
- Calling the K-SAS a measure of every impulse-control disorder or a diagnostic test
- Generalising one Japanese scale-validation sample to all languages and populations
What can you explain now?
What is the most accurate description of the K-SAS's role?
Compare with the explanation
It is an 11-item self-report scale that measures recent kleptomania-related symptom severity and impact; it does not diagnose every impulse-control disorder.
Its reliability and validity depend on the version, language, population and purpose, so results need wider assessment and context.
