Postpartum 1-Day CBT Pilot Study (Türkiye)

This pilot randomized controlled trial aims to evaluate the feasibility, acceptability, and preliminary effects of a culturally adapted, one-day online Cognitive Behavioral Therapy (CBT)-based group workshop for women with postpartum depression in Türkiye. The intervention was adapted from a validated model developed in Ontario, Canada, using Bernal's cultural adaptation framework.

Participants will be randomly assigned in a 1:1 ratio to either a workshop group, who will receive the one-day online CBT-based workshop within the first month after enrollment, or a control group who will continue to receive usual postpartum care throughout the study period. Data will be collected at baseline and at the 3-month follow-up using the Edinburgh Postnatal Depression Scale (EPDS), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), the Frequency of Actions and Thoughts Scale (FATS), and the TÜRBAD Satisfaction Questionnaire (TÜRBAD-SQ).

The study will assess feasibility indicators including recruitment, randomization procedures, completion of study questionnaires, retention through the 3-month follow-up, and adherence to the one-day workshop. Acceptability and preliminary changes in depressive, anxiety, and cognitive-behavioral outcomes will also be explored.

This pilot trial represents the first culturally adapted, one-day online CBT-based group intervention for postpartum depression in Türkiye and will inform the design of a future large-scale randomized controlled trial.
