The effectiveness of cognitive- behavioral therapy on quality of life in women with hypothyroidism in the reproductive age: a randomized controlled trial

BACKGROUND: Worldwide, hypothyroidism affects 3.7% of the population, and is associated with impaired quality of life. This study aimed to evaluate the effect of cognitive- behavioral therapy (CBT) on the quality of life in women with hypothyroidism. METHODS: 96 women with hypothyroidism randomly allocated into two groups: CBT group (n = 48) and control group (n = 48). Women in the CBT group were classified into four sub-groups of 12, and each sub-group received eight sessions of counseling (each session lasting 90 min). We collected data using a demographic questionnaire and the 36-Item Short Form Health Survey (SF 36) for measuring the quality of life. We used the independent t-test, chi-square test and ANCOVA to analyze the data. RESULTS: Five women from each group withdrew from the study, leaving 43 women in each group. The scores on physical functioning, physical health problems, social functioning and pain improved in the CBT group after the intervention, but the differences between the two groups were not significant. The scores on emotional health, emotional health problems, energy and emotions, and general health were significantly better in the CBT group than those in the control group (p < 0.05). CONCLUSION: Counseling using CBT can improve some aspects of quality of life, including emotional health, emotional health problems, energy and general health in patients with hypothyroidism.
