TO THE EDITOR:
Compulsive buying is defined as excessive spending that causes marked distress, financial difficulties, and significant interference with social or occupational functioning.1 Although a recent study suggests the lifetime prevalence of compulsive buying in the United States is 5.8%,2 there is no standard treatment. Preliminary research suggests cognitive-behavioral therapy (CBT) may help treat compulsive buying,3,4 but research is limited and other treatment options are needed. We present a case of a patient successfully treated using imaginal desensitization, motivational interviewing, and naltrexone.
Sonja, age 30, is a married, college-educated female with no children. She presents for psychiatric evaluation for out-of-control spending. Sonja spent >$12,000 over 2 years on clothing and personal effects and was $20,000 in debt and considering bankruptcy. Searching for “deals” and having the “newest” items are her central triggers. She endorses a childhood history of attention-deficit/hyperactivity disorder, alcohol abuse in late adolescence, compulsive stealing, and pathological gambling. Sonja had been abstinent from other impulse control problems, other than shopping for the last 4 years.
She begins a trial of naltrexone (50 mg/d) for 6 weeks and shows partial response in urge control but still presents as severely symptomatic. The CBT program is initiated after 6 weeks of naltrexone, and includes a novel treatment for impulse control disorders (ICD), “imaginal exposure,” which adds to the emerging literature on CBT for compulsive buying. Sonja undergoes weekly CBT, which includes motivational interviewing, imaginal exposures, financial planning, leisure planning, and cognitive restructuring. The 6-session therapy is a modification of a manualized treatment for pathological gambling, a related impulse control disorder.5 Session 1 includes psychoeducation and a motivational enhancement intervention. Session 2 focuses on functional analysis and behavioral strategies for managing compulsive buying and increasing healthy activities (eg, financial management, leisure skills). Session 3 introduces cognitive strategies for coping with urges to shop and changing irrational thinking. Session 4 includes imaginal desensitization. This session involves creating a script and audio taping a typical spending scenario in order to induce an urge to spend and then reduce that urge through review of negative consequences. Session 5 covers relapse prevention and includes preparing for future triggers and practicing asserting her needs with others. Session 6 includes family involvement, education, and therapy.
After 6, 1-hour, weekly therapy sessions, Sonja reports feeling in control of her buying behavior. She reports her urges to shop are substantially reduced and she will not go to a shopping venue without her husband or a friend until she feels comfortable going alone. Sonja has maintained her improvement for 6 months after the acute treatment. She reports that she continues to use the imaginal desensitization tapes approximately once a week. These 6 months have been her longest period of abstinence since her compulsive buying became a problem.
