Fear of being stigmatized is the most cited reason why individuals avoid psychotherapy. Conceptually, this fear should be strongest when individuals consider the reactions of those they interact with. Across 5 samples, the authors developed the Perceptions of Stigmatization by Others for Seeking Help (PSOSH) scale. In Sample 1 (N = 985), the 5 items of the PSOSH were selected ([alpha] = 0.91). In Sample 2 (N = 842), the unidimensional factor structure of the scale was examined across a diverse sample. In Sample 3 (N = 506), concurrent validity was supported through moderate associations with 3 different stigma measures (i.e., public stigma toward counseling, r = 0.31; public stigma toward mental illness, r = 0.20; and self-stigma, r = 0.37). In Sample 4 (N = 144), test-retest reliability across a 3-week period was calculated (0.82). Finally, in Sample 5 (N = 130), reliability ([alpha] = 0.78) and validity were explored with a sample experiencing symptoms of psychological distress. Relationships between variables (i.e., public stigma toward counseling, r = 0.31, and self-stigma, r = 0.40) were similar to those in previous samples. (Contains 4 tables.)
