افتراق افکار مزاحم های ناخواسته از سرکوب افکار: پرسشنامه خرس سفید بازداری چه چیزی را اندازه گیری می کند؟

The factor structure and correlational validity of a German version of the White Bear Suppression Inventory (Wegner, & Zanakos, 1994). Chronic thought suppression. Journal of Personality, 62, 615–640 was analysed in a sample of 276 non-clinical participants. Using orthogonal rotation, a two factor solution best represented the underlying structure. One factor was interpreted as “Unwanted Intrusive Thoughts”, the other as “Thought suppression”. The full scale's correlation with measures of depression, anxiety, and obsessive-compulsive behaviour was largely due to the Unwanted Intrusive Thoughts factor rather than the Thought Suppression factor. The Unwanted Intrusive Thoughts factor correlated negatively with avoidant coping. Neither factor correlated with self-disclosure. The theoretical meaning of separating thought intrusions from thought suppression is discussed, leading to the recommendation of differential assessment of these constructs.

2.1. Reliability and correlates with other measures The WBSI showed good internal consistency with a Cronbach's alpha of 0.88. The test–retest correlation after 3–6 weeks was satisfactory, r=0.78 (n=93; P<0.01). The WBSI's mean was slightly lower (M=40.11, SD=10.94) than that reported by Wegner and Zanakos (1994) and Muris et al. (1996). The correlations of the WBSI with the Beck Depression Inventory, the State-Trait-Anxiety Inventory, and the Maudsley Obsessive-Compulsive Inventory were similar to those reported by Wegner and Zanakos (1994) and Muris et al. (1996; see Table 2). As expected, the WBSI correlated positively with the Vigilance scale of the Mainz Coping Inventory, whereas the small but significant negative correlation with the MCI Cognitive Avoidance Scale and the zero correlation with the Self-Disclosure Scale did not support prior assumptions.
