Feasibility Study: Self-guided iCBT for Mothers With Postpartum Depression.

The purpose of this study is to conduct a feasibility study to test the study procedure and a newly developed self-guided internet-based cognitive behavioral therapy program for mothers with postpartum depression.

The aim of the feasibility study is twofold: 1) to test the feasibility of the study, and 2) to test the acceptability of the internet-based cognitive behavioral therapy program and to minimize dropout. The study will be conducted as a mixed-method process evaluation. Twenty mothers will be included in the study. After being informed about the study and its potential, all patients who give written informed consent will be randomized in a 1:1 ratio into either the control group, receiving treatment as usual, or the intervention group, receiving treatment as usual plus the iCBT program iCARE. The intervention period will last for two months. After the intervention period, investigators will use a survey distributed from REDCap to measure its feasibility, participants' satisfaction with it, and acceptability. After the two-month intervention period, semi-structured interviews will be conducted with participants from both the intervention and control groups to gather qualitative insights. This feasibility study will also provide a preliminary evaluation of the intervention's impact. The findings from this pilot study will inform the design of the subsequent randomized controlled trial (RCT) and guide any necessary modifications to the treatment program and associated procedures.
