This study aimed to determine the effectiveness of acceptance and commitment therapy (ACT) and life skill intervention on problem-solving style and relationship beliefs in male divorce applicants with worry symptoms. A quasi-experimental pre-test and post-test design were used in this research with two experimental groups and one control group. The statistical population of this study consisted of all male divorce applicants who referred to Iranmehr Counseling Center in Aliabad Katoul in 2018. The convenience sampling method was used to select samples from people who responded positively to the call, among whom 45 men were selected with scores higher than the mean on the Penn State Worry scale (1990), and randomly divided into two experimental groups and one control group (each group consisted of 15 people). Data were analyzed using SPSS-24 software and one-way and multivariate analysis of covariance.<strong> </strong>The research findings showed that life skill training (problem-solving) had a significant effect on problem-solving style and relationship beliefs and its subscales (P<0.05). ACT intervention also had a significant effect on both variables and their subscales (P<0.05).<strong> </strong>As a result, it can be stated that ACT and life skill interventions are effective on problem-solving style and relationship beliefs in male divorce applicants with worry symptoms.
