After reading each book title, a book discussion session was held. The research tool was Gillanders et al.'s cognitive fusion questionnaire (2015) and Sinha and Singh's students' social adjustment questionnaire (1993). Data analysis was done in two stages: descriptive statistics (mean and standard deviation) and inferential statistics (univariate covariance analysis test).

Also, based on covariance analysis, the effect of studying teenage novels on improving cognitive fusion was 0.82 and increased social adjustment was 0.78 in female students aged 13to 15.
