Randomized controlled trial of supportive-expressive group therapy and body-mind-spirit intervention for Chinese non-metastatic breast cancer patients

Abstract

Purpose

This study aimed to evaluate the efficacy of supportive-expressive group (SEG) therapy and body-mind-spirit (BMS) intervention on emotional suppression and psychological distress in Chinese breast cancer patients.

Methods

This three-arm randomized controlled trial assigned 157 non-metastatic breast cancer patients to BMS, SEG, or social support control group. SEG focused on emotional expression and group support, whereas BMS emphasized relaxation and self-care. All groups received 2-h weekly sessions for 8 weeks. The participants completed measurements on emotional suppression, perceived stress, anxiety, and depression at baseline and three follow-up assessments in 1 year.

Results

Using latent growth modeling, overall group difference was found for emotional suppression (χ ²(2) = 8.88, p = 0.012), marginally for perceived stress (χ ²(2) = 5.70, p = 0.058), but not for anxiety and depression (χ ²(2) = 0.19–0.94, p > 0.05). Post-hoc analyses revealed a significant and moderate reduction (Cohen d = 0.55, p = 0.007) in emotional suppression in SEG compared to control group, whereas BMS resulted in a marginally significant and moderate fall (d = 0.46, p = 0.024) in perceived stress. Neither SEG nor BMS significantly improved anxiety and depression (d < 0.20, p > 0.05).

Conclusions

The present results did not demonstrate overall effectiveness for either BMS or SEG therapy in the present sample of Chinese non-metastatic breast cancer patients. The participants appear to derive only modest benefits in terms of their psychological well-being from either intervention.
