Interventions Used in Practice to Reduce Prejudice and Stereotypes Toward Lesbian and Gay People: Theory Based Evaluation.

Various interventions are used in practice to reduce prejudice against lesbian women and gay men. Often these have not been developed or evaluated for effectiveness by researchers. In this study, we used theory-based evaluation (TBE) to determine whether the assumptions underlying three types of interventions (knowledge interventions, guessing games, and theater and movie interventions) often used in practice in the Netherlands are in line with evidence from the scientific literature.
