"When risk communication backfires: Randomized controlled trial on self-affirmation and reactance to personalized risk feedback in high-risk individuals": Correction to Schüz, Schüz, and Eid (2013).

Abstract

We conducted a full-factorial randomized controlled trial (N = 292; age 11-71) following a 2 * 2 design (UV photo yes/no, self-affirmation yes/no). Follow-up period was 2 weeks. Subsequent tanning behavior, sun avoidance intentions, and risk perception. A multivariate analysis of variance (MANOVA) revealed a three-way interaction between risk feedback, the self-affirmation manipulation, and risk status for the three outcome measures. Follow-up analyses of variance (ANOVAs) indicated that high-risk individuals receiving only the risk feedback intervention reacted defensively and reported higher exposure. A self-affirmation manipulation mitigates this reactance effect both on the level of cognitions and behavior. Self-affirmation has influential implications not only for Social Psychology but also for health prevention measures. The findings support the effectiveness of self-affirmation in reducing reactant and defensive reactions to personalized visual risk feedback. Interactions with health risk status indicate that self-affirmation might increase the effectiveness of health promotion messages in high-risk populations. (PsycINFO Database Record
