Transdiagnostic therapy compared to progressive muscle relaxation on the emotional health of mothers with premature infants: A randomized controlled trial.

Objective: The aim of this study was to compare the effects of transdiagnostic therapy compared to progressive muscle relaxation (PMR) on emotion regulation strategies, self-compassion, maternal role adaptation, and social and work adjustment in mothers of premature infants.

Materials and methods: This was a randomized controlled trial with two groups and pre-test, post-test, and a two-month follow-up assessment. Included were 27 mothers randomly assigned to either the transdiagnostic therapy group or the PMR group (13 in the transdiagnostic group and 14 in the PMR group). The experimental group received eight sessions of transdiagnostic therapy while the control group received eight sessions of PMR. The participants completed the following scales: Emotion Regulation Questionnaire, Self-Compassion Scale, Maternal Role Adaptation Scale, and Work and Social Adjustment Scale.

Results: Transdiagnostic therapy was significantly more effective than PMR in improving emotion regulation strategies, self-compassion, maternal role adaptation, and social and work adjustment based on the between-group comparison conducted at post-test and follow-up (p < 0.01).

Conclusion: Transdiagnostic therapy was shown to be effective in improving the emotional health of mothers with premature infants and was more effective than PMR techniques.
