This research aimed to investigate the effectiveness of the integrated model of acceptance and commitment and schema therapy on the feeling of loneliness and social problem-solving of people with Prolong Grief Disorder. This research was a semi-experimental type with a pre-test-post-test design and a control group. The statistical population of the research included all the people with Prolong Grief Disorder according to DSM 5-TR criteria and referred to the Acceptance and Commitment Psychological Clinic in Tehran in 2022. From the mentioned population, 20 people who met the criteria for entering the research were selected by purposeful sampling and randomly assigned to two groups of 10 people. The subjects of the experimental group were subjected to the integrated model of acceptance and commitment and schema therapy for 10 sessions of 120 minutes once a week. The control group did not receive any intervention. The research tools included the loneliness questionnaire of Russell & Cutrona (1980) and the social problem-solving questionnaire of D'zurilla & Nezu (1990). To analyze the data, multivariate covariance analysis was used. The findings showed that in the experimental group, the average scores of the post-test compared to the pre-test had changed (P<0.05). From these findings, we can conclude that this method can be an efficient way to work with people with Prolong Grief Disorder.
