Mood states preceding and following compulsive buying episodes: an ecological momentary assessment study.

This study examined the extent to which patterns of mood and daily stress experienced by individuals with compulsive buying (CB) are associated with CB episodes by using Ecological Momentary Assessment. The comparison of mood and the impact of daily stress on days on which CB occurred to those days on which CB episodes did not occur did not reveal any significant differences. Within-day analysis indicated that negative affect increased significantly and positive affect decreased significantly prior to a CB episode. There was also evidence of a significant decrease in negative affect following a CB episode. Positive affect did not change significantly after a CB episode. The findings suggest that CB episodes hold negative reinforcing properties for individuals with CB. Treatment of patients with CB should focus on functional assessment of the affective antecedents and consequences of CB episodes and the identification of alternative, more functional behaviors to deal with these affective states.
