This study examined whether positive self-talk combined with behavioral reinforcement could improve self-esteem in young adult women. 10 participants were randomly assigned to an experimental group, who wrote and said positive statements about themselves daily before washing hands and eating, or a control group. Both groups completed a self-esteem questionnaire before and after. Results showed no significant differences between groups over time, but a significant interaction effect, suggesting positive self-talk may have improved self-esteem when combined with reinforcement but not on its own. Further research is needed to understand these interpretive findings.
