Compulsive shopping disorder is characterized by repetitive, often impulsive engagement in shopping behaviors that produce immediate gratification despite long-term harmful consequences. Although not formally classified as a distinct disorder in DSM-5 (where it falls under 'Other Specified Disruptive, Impulse-Control, and Conduct Disorder'), it shares significant phenomenology with addictive disorders, with proposed inclusion in ICD-11 as 'compulsive buying-shopping disorder' under impulse control disorders.
The behavioral cycle typically involves four phases: anticipation (preoccupation with shopping, urges, planning), preparation (researching items, comparing prices, scheduling shopping), shopping itself (described as exhilarating, with feelings of being in a 'flow state'), and post-purchase (initial pleasure followed by guilt, shame, financial worry, and resolutions to stop). The pattern of escalating purchases, attempts to control buying, continuation despite consequences, and withdrawal-like distress when unable to shop closely parallels substance addiction.
Etiology involves multiple interacting factors: temperamental traits including high impulsivity, novelty-seeking, and reward sensitivity; emotional dysregulation with shopping serving as maladaptive emotional coping; cognitive distortions about buying as identity affirmation or stress relief; cultural messaging promoting consumption; and online shopping accessibility removing impulse control barriers. Common comorbidities include depression (50-70%), anxiety disorders (50%), substance use disorders (30%), eating disorders, and other behavioral addictions. Treatment integrates cognitive-behavioral therapy targeting buying-related cognitions and behaviors, group therapy modeled on addiction recovery (Debtors Anonymous, Spending Fasts), financial counseling and debt management, and pharmacotherapy with SSRIs, naltrexone, or topiramate showing modest evidence.
