The Effectiveness of Psychological Well-being Training on Negative Automatic Thoughts and Resilience of Female Adolescents with Rumination in Tehran

Background: While there is a strong link between rumination and internalizing psychopathology over the lifespan, the development of rumination is not well understood. This study aimed at investigating the effectiveness of psychological well-being training on negative automatic thoughts and resilience of female adolescents with rumination in Tehran. Methods: The present study followed a quasi-experimental pretest-posttest design with a control group. The study population was all female adolescents with rumination in District 6, Tehran, Iran in 2018-2019. Sample of the study included 30 adolescent girls with rumination, referred to counseling centers and psychological services in Tehran. They were selected through convenience sampling and randomly assigned to experimental (n = 15) and control (n = 15) groups. The experimental group received psychological well-being interventions (10 one-hour training sessions, one session per week). Then, female adolescents with rumination in both groups underwent a posttest. The instruments used included the Negative Automatic Thoughts Questionnaire (ATQ-N, Ingram et al. 1995), and the Resilience Questionnaire (Connor and Davidson, 2003). The data were analyzed by SPSS software version 23. Results: The results showed that 6.6% in the experimental group and 11.11% in the control group were 14 years old. Moreover, psychological well-being training was significantly effective in negative automatic thoughts (F= 50.89, P=0.001), and resilience (F= 1.24, P=0.001) of adolescents with rumination (p>0.05). Conclusion: The 10-session Psychological well-being training was effective on negative automatic thoughts and resilience of adolescents with rumination in Tehran
