Methods: This randomized controlled trial was conducted on 74 women in Saqez-Iran, 2017.

Participants were assigned into two groups of intervention and control through blocked randomization.

The intervention group received cognitive-behavioral therapy in 8 sessions of 45 to 60 minutes.

Beck’s depression questionnaire was completed, and body mass index (BMI) was calculated before and four weeks after the end of the intervention.

ANCOVA test was used to analyze the data.

Results: There was no significant difference between the two groups in terms of socio-demographic characteristics (P > 0.05).

After the intervention, the mean (SD) of depression score in the intervention group was 4.5 (3.9) and in the control group 16.5 (8.6).

Based on the ANCOVA test and with adjusting the baseline values, the mean depression score of the intervention group significantly was lower than the control group (adjustedmeandifference: -13.8; confidence interval 95% = -10.9 to -16.7; P< 0.001).

In addition, after the intervention, themean(SD) of BMIin the interventiongroupwas27.3 (5.4), andin the controlgroupitwas29.4 (5.5).

The intervention group was significantly lower than the control group, based on the ANCOVA test with adjusting the baseline values (-0.6; -0.2 to -0.9; P < 0.001).

Conclusions: Cognitive-behavioral therapy is effective in improving depression and decreasing BMI in women with PCOS.

Therefore, it is recommended to use this therapeutic approach to improve the physical and psychological health of these women.
