The rampant conflation between having a sexual interest in children and engaging in acts of sexual abuse contributes substantially to high levels of stigma directed toward people living with a sexual interest in children. Stigmatization and societal punitiveness surrounding people living with these interests can impact their well-being, obstruct help-seeking, and potentially increase risk of offending behavior. Previous research employing stigma intervention strategies have shown promising results in reducing stigmatizing attitudes toward this population, particularly regarding presentations of lived-experience narratives. The present study sought to examine the effectiveness of humanizing narrative (lived experience of an individual with sexual interest in children) and informative (fact-based information about pedophilia) antistigma interventions on members of the general public. Using a repeated measures experimental design, participants (N = 694) were randomly assigned one of two intervention videos as part of an anonymous online survey. Attitudes toward people with sexual interest in children (including cognitive, affective, and behavioral responses) were assessed pre- and post-intervention, using scales modified for valence framing effects and researcher-developed items. Both interventions were associated with reductions on all measured aspects of stigma, with the exception of perceptions of controllability, which neither intervention influenced. Although effects between interventions were similar, the informative intervention was associated with greater reductions in perceptions of dangerousness and increased understanding that sexual interest in children is not a choice. Implications for stigma-reduction interventions and future research are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved)
