Stopping Overshopping: An Approach to the Treatment of Compulsive-Buying Disorder

Treatment of compulsive buying disorder: comparing the effectiveness of cognitive behavioural therapy with person-centred experiential counselling

Background:

Outcome studies of the treatment of compulsive buying disorder (CBD) have rarely compared the effectiveness of differing active treatments.

Aims:

This study sought to compare the effectiveness of cognitive behavioural therapy (CBT) and person-centred experiential therapy (PCE) in a cross-over design.

Method:

This was an ABC single case experimental design with extended follow-up with a female patient meeting diagnostic criteria for CBD. Ideographic CBD outcomes were intensively measured over a continuous 350-day time series. Following a 1-month baseline assessment phase (A; 28 days; three sessions), CBT was delivered via 13 out-patient sessions (B: 160 days) and then PCE was delivered via six out-patient sessions (C: 63 days). There was a 99-day follow-up period.

Results:

Frequency and duration of compulsive buying episodes decreased during active treatment. CBT and PCE were both highly effective compared with baseline for reducing shopping obsessions, excitement about shopping, compulsion to shop and improving self-esteem. When the PCE and CBT treatment phases were compared against each other, few differences were apparent in terms of outcome. There was no evidence of any relapse over the follow-up period. A reliable and clinically significant change on the primary nomothetic measure (i.e. Compulsive Buying Scale) was retained over time.

Conclusions:

The study suggests that both CBT and PCE can be effective for CBD. Methodological limitations and suggestions for future CBD outcome research are discussed.

Cognitive behavioral therapy for compulsive buying behavior: Predictors of treatment outcome

BACKGROUND

Compulsive buying behavior (CBB) is receiving increasing consideration in both consumer and psychiatric-epidemiological research, yet empirical evidence on treatment interventions is scarce and mostly from small homogeneous clinical samples.

OBJECTIVES

To estimate the short-term effectiveness of a standardized, individual cognitive behavioral therapy intervention (CBT) in a sample of n=97 treatment-seeking patients diagnosed with CBB, and to identify the most relevant predictors of therapy outcome.

METHOD

The intervention consisted of 12 individual CBT weekly sessions, lasting approximately 45minutes each. Data on patients' personality traits, psychopathology, sociodemographic factors, and compulsive buying behavior were used in our analysis.

RESULTS

The risk (cumulative incidence) of poor adherence to the CBT program was 27.8%. The presence of relapses during the CBT program was 47.4% and the dropout rate was 46.4%. Significant predictors of poor therapy adherence were being male, high levels of depression and obsessive-compulsive symptoms, low anxiety levels, high persistence, high harm avoidance and low self-transcendence.

CONCLUSION

Cognitive behavioral models show promise in treating CBB, however future interventions for CBB should be designed via a multidimensional approach in which patients' sex, comorbid symptom levels and the personality-trait profiles play a central role.
