Abstract

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.
