Suppression of obsession-like thoughts in nonclinical individuals: impact on thought frequency, appraisal and mood state.
Wegner's (1994, Psychological Review, 101, 34-52) research on the paradoxical effect of thought suppression has been incorporated into contemporary cognitive-behavioural models of obsessive-compulsive disorder. However, findings on the effects of thought suppression on thought frequency have been inconsistent and few studies have actually examined the suppression of thoughts that are obsessional in nature. In the present study 219 nonclinical participants were randomly assigned to suppress or not suppress a neutral, obsessional or positive thought during an initial monitoring interval. In a second thought monitoring interval, all participants received instructions not to suppress their target thought. No paradoxical effect of suppression on frequency was observed for any type of thought, although suppression of obsessional thoughts was associated with greater subsequent discomfort and a more negative mood state than suppression of positive or neutral target thoughts.
