Internet-Delivered Cognitive Behaviour Therapy for Depression and Anxiety in Perinatal Parents

This study evaluates the effectiveness of the Wellbeing Course for New and Expecting Parents (WCNEP), an internet-delivered cognitive behavioral therapy (ICBT) intervention, in reducing symptoms of anxiety and depression in perinatal parents, within a routine care online therapy clinic (the Online Therapy Unit). The study aims to assess treatment uptake, perceptions, feasibility, and effectiveness of the WCNEP in routine care among birthing and non-birthing parents. Over the duration of 8 weeks, participants will review course materials online and respond to questionnaires aimed at assessing changes in various outcomes over time.

Depression and anxiety in the perinatal stage are associated with adverse outcomes such as pregnancy and birth complications, developmental impacts on the baby, relationship issues and poor wellbeing with the partner. Despite these challenges, barriers such as stigma and shame, poor understanding and awareness of symptoms, and lack of treatment availability prevent access to treatment.

Internet-delivered cognitive behaviour therapy (ICBT) is an effective and accessible treatment. The Online Therapy Unit (OTU) routinely delivers ICBT programs for various concerns to Saskatchewan residents. ICBT programs offered by OTU have shown great success, particularly in addressing symptoms of depression and anxiety. Furthermore, previous trials conducted by OTU - Maternal Depression Online and Wellbeing Course for New Moms - have demonstrated the effectiveness of the programs in addressing postnatal depression and anxiety among birthing parents.

Despite the effectiveness of these programs, they were limited in scope; Maternal Depression Online was primarily designed to address depression, and both programs were offered exclusively to postnatal birthing parents. Accordingly, the Wellbeing Course for New and Expecting Parents (WCNEP) has been developed as an 8-week transdiagnostic ICBT program for perinatal birthing and non-birthing parents experiencing depression and/or anxiety. To develop the WCNEP, the Wellbeing Course for New Moms was adapted for parents across the perinatal stage by revising the program content and incorporating additional patient stories of perinatal birthing and non-birthing parents.

Although recruitment and service provision will include both birthing and non-birthing perinatal parents, the Course will be evaluated in two phases. In phase 1, the investigators will evaluate the Course for perinatal birthing parents. In phase 2, the investigators will evaluate the course for non-birthing parents. Prospective clients may learn about the WCNEP from advertisements to the public, healthcare providers, and community organizations. Interested clients will be directed to the study website to complete a screening protocol. Clients will subsequently book and complete a telephone screening with an OTU therapist. Following the telephone screening, eligible clients will be enrolled in the WCNEP. Participants will have access to five lessons that they will complete in consecutive order with 1 to 2 weeks between lessons. They will be asked to complete questionnaires at various time points, and provided with homework activities to complete after each lesson. Participants will also have access to therapist support for a minimum of 8 weeks, which can be extended up to 12 weeks in the event that the birth of a child or some unexpected event occurs during the duration of the Course. After completing treatment, a subset of participants will take part in a semi-structured interview for feedback on overall course content and specific course components (i.e., patient stories).

The overall goals of the study are to evaluate the effectiveness of the intervention on various outcomes in perinatal parents over time, and the uptake of and engagement with different components (e.g., patient stories) of the treatment.
