Abstract :
BACKGROUND: Among the cardiovascular diseases (CVDs), myocardial infraction (MI) is one of
the main causes of mortality around the world. A diagnosis of MI may be followed by
psychological problems, such as depression, anxiety, and stress. Therefore, psychological
interventions can be beneficial in routine treatment. The purpose of this study was to compare
the effect of cognitive-behavioral therapy (CBT) and dialectical behavioral therapy (DBT) on
perceived stress and coping skills in patients after MI.
METHODS: This study was a randomized clinical trial with a pretest-posttest design and control
group. The statistical population consisted of 45 patients after MI who referred to Noor Heart
Clinic in Rasht, Iran, between 2018 and 2019. They were randomly divided into 3 groups of
15 individuals (2 interventions including CBT and DBT, and 1 control group). In the intervention
groups, participants underwent 8 weekly 90-minute sessions. Data were collected using a 3 part
self-report questionnaire including a demographic information form, the Ways of Coping
Questionnaire (WCQ), and the Perceived Stress Scale -14 (PSS-14). The statistical methods used
for data analysis included chi-square test, one-way ANOVA, repeated-measures ANOVA, and
post hoc Bonferroni test.
RESULTS: We found significant main effects of group (F(2,42)=6.11; P=0.005) and time
(F(2,84)=28.48; P<0.001), and a significant group-by-time interaction (F(4,84)=8.97; P<0.001) on
perceived stress scores. For problem-focused coping scores, findings indicated significant main
effects of group (F(2,42)=7.33; P=0.002) and time (F(2,84)=30.71; P<0.001), and a significant
group-by-time interaction (F(4,84)=12.86; P<0.001). For emotion-focused coping scores, the
results also indicated significant main effects of group (F(2,42) = 17.41; P < 0.001) and time
(F(2,84)=31.74; P<0.001), and a significant group-by-time interaction (F(4,84)=14.90; P<0.001).
CONCLUSION: The current study revealed that DBT was more effective in improving emotionfocused
coping than CBT.
