The WBSI is a 15-item questionnaire that is designed to measure thought suppression. Chronic thoughts suppression is a variable that is related to obsessive thinking and negative affect associated with depression and anxiety. The WBSI can help to identify individuals who are more prone to develop chronic thought suppression as well as individuals who express wishing they were not depressed, but are in fact depressed. The measure can also be used by practitioners to evaluate changer over time.
Scoring: The scoring of the WBSI is based on a 5 point scale from Strongly disagree (1) to Strongly agree (5). The total score is obtained by summing up the responses that are provided by respondents. The total score can range from 15 to 75. Higher scores on the WBSI indicate greater tendencies to suppress thoughts.
Reliability: The WBSI has very good internal consistency, with alphas ranging from .87 to .89. The WBSI has also been found to have good stability with a 1 week test-retest correlation of .92, and a 3 week to 3 month test-retest correlation of .69.
Validity: Demonstrates excellent convergent validity with significant correlations between the WBSI and several measures including Beck’s Depression Inventory (BDI), the Maudsley Obsessive-Compulsive Inventory, and the State-Trait Anxiety Inventory (STAI). It has also been found that the WBSI correlates negatively with repression, thus suggesting that the WBSI measures a characteristic that is different to traditional concepts of repression.
