Day # 179: Kleptomania
Today's Content Level: Intermediate
Introduction
Kleptomania is a disorder characterized by recurrent difficulty resisting impulses to steal items that are not needed for personal use or monetary value.
The theft is typically preceded by rising tension and followed by pleasure, relief, or gratification. Guilt, shame, and fear of legal consequences commonly follow.
Kleptomania is not synonymous with shoplifting. Most shoplifting is purposeful—for financial gain, personal use, peer pressure, anger, or other motives—whereas kleptomania involves recurrent, ego-dystonic urges to steal items that are often of little practical value to the individual.
It is an uncommon, underrecognized disorder. Many patients do not disclose symptoms unless directly and nonjudgmentally asked, often because of shame or concern about legal consequences.
Diagnostic Criteria 1
Recurrent failure to resist impulses to steal objects that are not needed for personal use or monetary value.
Increasing sense of tension immediately before the theft.
Pleasure, gratification, or relief at the time of the theft.
The stealing is not committed to express anger or vengeance and is not in response to a delusion or hallucination.
The stealing is not better explained by conduct disorder, a manic episode, or antisocial personality disorder
Epidemiology
Prevalence: Estimates in the general population are generally below 1%, commonly cited around 0.6–0.8%. True prevalence is uncertain because symptoms are often concealed and research samples are small.
Age of onset: Symptoms most often begin in adolescence or early adulthood, although presentation for treatment may occur much later.
Gender differences: Clinical samples suggest that kleptomania is more commonly identified in women. This may partly reflect referral patterns, help-seeking, and legal-system differences rather than a definitive biological sex difference.
Course/prognosis: The course is often chronic or fluctuating. Untreated symptoms can cause substantial legal, occupational, financial, family, and psychological consequences. Arrests and incarceration are common in clinical samples, although a legal consequence alone does not establish the diagnosis.
Pathogenesis / Risk Factors
The etiology is not fully understood and is likely multifactorial.
Kleptomania has features that overlap with:
Impulse-control disorders: impulsivity and difficulty delaying behavior.
Obsessive-compulsive spectrum disorders: intrusive, repetitive urges and attempts to resist them.
Addictive disorders: craving-like urges, short-term reward or relief, and continued behavior despite serious adverse consequences.
Common clinical associations include mood disorders, anxiety disorders, substance use disorders, eating disorders, and other impulse-control disorders.
New-onset stealing behavior, especially later in life, warrants assessment for possible neurologic, cognitive, medication-related, substance-related, manic, or psychotic contributors.
History: A nonjudgmental, direct approach is essential. Consider asking:
“Have you ever had recurrent urges to take things you did not need?”
“Do you feel tension or anxiety before taking something?”
“What do you feel immediately afterward—relief, pleasure, guilt, shame?”
“Are the items used, kept, discarded, returned, or given away?”
“Was the behavior planned for financial gain, revenge, peer acceptance, or another purpose?”
“Do episodes occur during intoxication, elevated mood, psychosis, dissociation, or severe stress?”
“What legal, occupational, interpersonal, and financial consequences have occurred?”
Additional assessment should include:
Mood symptoms, including a history of mania/hypomania.
Substance use and medication review.
Obsessions, compulsions, and other repetitive behaviors.
Eating-disorder symptoms and impulsive behaviors.
Trauma history when clinically indicated.
Neurologic history, including traumatic brain injury, seizures, cognitive decline, or frontal-lobe symptoms.
Suicide risk, particularly when shame, legal jeopardy, depression, or hopelessness are prominent.
MSE: The mental status exam may be normal, particularly if the patient is not currently experiencing urges. Possible findings include:
Anxious, depressed, ashamed, or guarded affect.
Limited insight into triggers or behavioral patterns.
Intact awareness that stealing is wrong.
No psychosis or mania when kleptomania is the primary diagnosis.
Impulsivity or difficulty describing how urges escalate.
Optional Questionnaires: There is no widely used, universally accepted screening questionnaire for routine clinical practice. These tools can support assessment and monitoring but do not replace a careful diagnostic interview and differential diagnosis.
Structured Clinical Interview for Kleptomania (SCI-K): A DSM-based structured interview with promising preliminary reliability and validity data.
Kleptomania Symptom Assessment Scale (K-SAS): A symptom-severity measure used in research and treatment monitoring.
Kleptomania Yale-Brown Obsessive-Compulsive Scale (K-YBOCS): A modified symptom measure used in clinical trials.
Differential Diagnosis and Comorbidities:
Non-kleptomania theft/shoplifting: Theft for money, desired items, revenge, peer approval, rebellion, or instrumental gain is not kleptomania.
Conduct disorder: Theft occurs within a broader pattern of violating the rights of others or major social norms.
Antisocial personality disorder: Theft is generally part of pervasive disregard for and violation of others’ rights rather than an ego-dystonic, tension-relieving impulse.
Bipolar disorder: Stealing may occur during mania or hypomania in the context of elevated/irritable mood, decreased need for sleep, grandiosity, increased goal-directed activity, and other disinhibited behaviors.
Psychotic disorders: Theft driven by delusions or hallucinations does not meet criteria for kleptomania.
Obsessive-compulsive disorder: OCD compulsions are generally performed to reduce distress from obsessions or prevent a feared event; kleptomania involves an urge to steal followed by gratification or relief.
Substance intoxication or withdrawal: Assess whether episodes are temporally related to substances.
Neurocognitive disorder, traumatic brain injury, seizure disorder, or other neurologic illness: Consider especially with late onset or a marked change from baseline.
Common comorbidities include depressive, anxiety, substance use, eating, and other impulse-control disorders.
General Approach
Treatment should be compassionate, nonjudgmental, and individualized.
Establish the diagnosis carefully and address immediate safety, legal, occupational, and relational consequences.
Identify triggers, high-risk settings, access to money or stores, emotional antecedents, and patterns of secrecy.
Treat co-occurring disorders, including depression, bipolar disorder, anxiety, substance use disorders, ADHD, and eating disorders, when present.
Encourage a practical relapse-prevention plan, such as avoiding high-risk shopping situations, shopping with a support person when appropriate, limiting unstructured exposure to triggering settings, and tracking urges.
Psychosocial Interventions
Cognitive behavioral therapy (CBT) is generally considered the preferred psychotherapy approach, although the evidence base is limited.
CBT interventions may include:
Trigger identification and functional analysis.
Urge monitoring.
Cognitive restructuring of permissive or hopeless thoughts.
Coping skills for tension, distress, and cravings.
Relapse-prevention planning.
Stimulus control and reduction of exposure to high-risk situations.
Imaginal exposure or covert sensitization in selected cases.
Psychotherapy should also address shame, secrecy, comorbid symptoms, and the patient’s social supports. Evidence is limited by the small number of controlled studies, but CBT-based approaches are commonly recommended.
Pharmacotherapy
There is no FDA-approved medication specifically for kleptomania.
Medication is generally considered when symptoms are moderate to severe, psychotherapy alone is insufficient, urges are intense, or clinically significant comorbidities are present.
Naltrexone has the strongest controlled-trial evidence. In a small 8-week randomized controlled trial, naltrexone was associated with greater reductions in stealing urges, stealing behavior, and overall symptom severity than placebo. It remains an off-label option and requires assessment of opioid use, medical contraindications, and appropriate laboratory/clinical monitoring.
SSRIs, SNRIs, mood stabilizers, and anticonvulsants have been described in case reports, open-label studies, or small series. They may be reasonable when targeting a comorbid condition or when the clinical presentation suggests a relevant symptom domain, but evidence for kleptomania itself remains limited.
Medication selection should be guided by:
Co-occurring psychiatric disorders.
Substance use history.
Presence of cravings or reward-driven urges.
Medical history and adverse-effect risk.
Prior medication response.
Conclusion
Kleptomania is a rare but potentially severe disorder involving recurrent urges to steal items that are not needed, rising tension before theft, and relief or gratification afterward.
It is distinct from ordinary or instrumental shoplifting.
Patients often experience substantial shame and may not disclose symptoms unless asked directly and respectfully.
Diagnosis requires careful exclusion of theft related to conduct disorder, antisocial personality disorder, mania, psychosis, substance effects, and neurologic conditions.
CBT-based treatment, management of comorbidities, relapse-prevention strategies, and selected off-label pharmacotherapy—particularly naltrexone—may reduce symptoms.
