The 21-item Compulsive Sexual Behavior Consequences Scale (CSBCS) detected changes in symptoms over the course of the 12-week period. Items related to intimate relationships were most resistant to change, and items related to intrapersonal conflict and impulse control were most likely to change. There were no differences in the reduction of consequences between medication and placebo groups. Consequences of CSB correlated only moderately with frequency measures which suggest that these constructs should be examined separately. The findings suggest that measuring the consequences of CSB can reveal important clues about the personal domains most affected by CSB, identify those domains that are resistant to change, and aid in individualized treatment planning. Study data were obtained during a randomized, parallel-group, placebo-controlled study that assessed the effectiveness and tolerability of citalopram during a 12-week treatment program for 28 outpatient subjects with CSB. The primary outcome measure was the CSBCS, which was adapted from the Inventory of Drug Use Consequences. A second measure, the Primary Appraisal Measure: Compulsive Sexual Behavior, was adapted from the Drug and Alcohol Primary Appraisal measure. 3 tables and 27 references
