Effectiveness of Rational Assertiveness Training in Reducing Interpersonal Problems: Single-Subject Design

Abstract

This research aimed to investigate the effectiveness of rational assertiveness training in reducing interpersonal problems in a single subject. Current literature indicates that adolescents typically adopt maladaptive strategies to resolve conflicts. Hence, suggesting the need to equip them with effective interpersonal strategies. One such tool is rational assertiveness training which creates assertiveness by modifying cognitions and behaviours. This was a pre-and post-intervention quantitative design using a 21-year-old female as its subject. The findings approved the hypothesis. Post-intervention assessment showed significant increase in level of assertiveness, as well as significant decrease in interpersonal problems as compared to pre-intervention assessment. Future researchers are advised to incorporate other methods of assessment, such as accounts of parents, to reduce social desirability. Additionally, the duration of the training is too short to produce long lasting changes, hence future studies may elaborate the training.
