Participants who scored 5 or above on Patient Health Questionnaire (PHQ-9) will be would be recruited and randomly assigned into one of two groups (experimental or controlled). Experimental groups will receive the online LTP+CaCBT treatment - the intervention will consist of a total of 12 group training sessions (approx. 60 minutes each). The controlled groups will receive 'placebo effects' in the form of psychoeducation involving basic discussions around mother-child relationships, childcare, child nursing related activities and general maternal discussions. Each of the two groups (both experimental and controlled) will be comprised of approximately 10 mother-child pairs per sub-group.
The pilot trial aims to test the feasibility, acceptability and cultural appropriateness of online LTP+CaCBT for treating postnatal depression and to improve the mental health and wellbeing of mothers and their children in the UK.
