Abstract
Background & Objectives: The family's warm and emotional atmosphere is threatened by conflict, fighting, and parental divorce. Divorce is the most significant indicator of marital turmoil and is one of the most stressful sources that can disrupt people's cognitive structures. Divorce in the family does not only harm the psychological processes of the couple but also injures the psychological health of the children. One of the effects and consequences of family disputes like divorce is emotional disorders in children, which reduces their quality of life. Also, self–criticism in children is one of the consequences of grief caused by parents' divorce in children. Since psychological injuries caused by divorce in family members appear persistently and affect their well–being, the necessity of psychological interventions is raised. One of the interventions that can affect the cognitive regulation of emotion and self–criticism in children of divorced families is acceptance and commitment therapy. Therefore, the present study was conducted to investigate the effectiveness of acceptance and commitment–based therapy on cognitive regulation of emotion and self–criticism in adolescent girls experiencing parental divorce mourning.
Methods: The current research method was quasi–experimental and employed a pretest–posttest and a 3–month follow–up design with a control group. The statistical population included all teenagers aged 14–16 from divorced families living in Tehran City, Iran, in 2018. The sampling method was purposeful, and 30 people were selected as a sample based on the inclusion and exclusion criteria. The inclusion criteria were as follows: female gender, being between 14 and 16 years old, scoring above the cut–off point on the Grief Reaction Checklist (180 and above), and being in a divorced family. The exclusion criteria were as follows: withdrawal from participation in the study and absence of more than two therapy sessions. Data were gathered in two groups via (pretest, posttest, and follow–up) via the Grief Reaction Checklist (Hogan et al., 2001), the Cognitive Emotion Regulation Questionnaire (Garnefski & Kraaij, 2006), and the Levels of Self–criticism Scale (Thompson & Zuroff, 2004). The experimental group received eight sessions of acceptance and commitment therapy (Forman and Herbert, 2008), and the control group was put on the waiting list to receive the intervention sessions if they tended after the end of the research. After completing the training period, a posttest was administered to both the experimental and control groups, and three months after the end of the intervention sessions, the experimental group was followed up again with research tools. Participants were assured that the results would be used only for research work and that the information and data would remain confidential. Data analysis was performed using descriptive statistics, including mean, standard deviation, and inferential statistics, including analysis of variance with repeated measures and Bonferroni post hoc test in SPSS software version 22. The significance level of statistical tests was set at 0.05.
Results: The results showed that in the experimental group, the difference in the mean scores of adaptive and maladaptive strategies of cognitive emotion regulation and self–criticism in the pretest–posttest and pretest–follow–up was statistically significant (p<0.001). However, the difference in the mean scores in the posttest–follow–up was not significant (p=1.00). Also, the difference in the mean scores of adaptive and maladaptive strategies of cognitive emotion regulation and self–criticism in the experimental group was statistically significant compared to the control group (p<0.001).
Conclusion: According to the results of the present study, acceptance and commitment therapy positively reduce self–criticism and maladaptive components of cognitive emotion regulation. It also has a positive and improving effect on increasing the adaptive components of cognitive emotion regulation. Therefore, acceptance and commitment therapy can be used as an intervention method in adolescent children of divorced families.
