Clinical Trial Summary

In the proposed study, the investigators will examine the efficacy of transdiagnostic, Internet-delivered cognitive behaviour therapy (ICBT) in the treatment of postpartum anxiety and depression. Half of participants will receive the treatment immediately, and half of the participants will be assigned to a treatment-as-usual control condition. Participants assigned to the control condition will be offered the treatment after a 12-week waiting period, although data from this portion will not be included in the current study. All participants will complete questionnaires prior to the start of the treatment, following treatment (or corresponding 8-week waiting period), at 1-months follow-up (or corresponding 12-week waiting period), and at 6-months follow-up (in those assigned to the treatment condition). Further, those who receive the treatment will complete questionnaires on a weekly basis. The primary outcome measures include anxiety and depression. As part of the battery of questionnaires administered after the completion of the program, participants will be asked to rate the program content, the overall service, and their satisfaction with the program.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in postpartum depression	Measured by the Edinburgh Postnatal Depression Scale (EPDS). 10 items are summed into a total score ranging from 0 to 30, with higher scores indicating more severe depression.	Baseline, weeks 1-9, 13, and 37
Primary	Change in anxiety	Measured by the Generalized Anxiety Disorder Scale 7-Item (GAD-7). 7 items are summed into a total score ranging from 0 to 21, with higher scores indicating more severe self-reported levels of anxiety.	Baseline, weeks 1-9, 13, and 37
Secondary	Change in depression	Measured by the Patient Health Questionnaire 9-Item (PHQ-9). 9 items are summed into a total score, with scores ranging from 0 to 27. Higher scores are associated with higher depression severity.	Baseline, weeks 1-9, 13, and 37
Secondary	Change in depression, anxiety, stress	Measured by the Depression and Anxiety Stress Scales (DASS-21). 21 items are summed into a total score ranging from 0 to 42, with higher scores indicating more severe symptoms with respect to the depression, anxiety, and stress subscales.	Baseline, 8 weeks, 1 month, and 6 months
Secondary	Mother-infant bonding	Measured by the Postnatal Bonding Questionnaire (PBQ). 25 items are summed into a total score ranging from 0 to 125, with higher scores indicating more reported difficulties bonding with one's baby.	Baseline, weeks 9, 13, and 37
Secondary	Relationship satisfaction	Measured by the Dyadic Adjustment Scale-7 item (DAS-7). 7 items are summed into a total score ranging from 0 to 32, with higher scores indicating greater perceived relationship quality.	Baseline, weeks 9, 13, and 37
Secondary	Treatment credibility	Measured by the Credibility/Expectancy Questionnaire (CEQ). 6 items are summed into a total score and two subscales (credibility and expectancy). Total scores can range from 3 to 27, with higher scores representing greater perceptions of ICBT credibility.	Baseline and week 9
Secondary	Therapeutic alliance	Measured by the Working Alliance Inventory-Short Revised (WAI-SR). Scores are summed into three sub-total scores, which respectively assess various domains of the therapeutic relationship (i.e., goal, task, and bond). Sub-total scores each range between 5 and 20, with higher scores representing better therapeutic relationship in each of the three domains assessed.	9 weeks following baseline
Secondary	Treatment satisfaction	Measured by the Treatment Satisfaction Questionnaire (TSQ). 6 items are scored using various scales. Descriptive statistics are produced for each item.	9 weeks following baseline
Secondary	Adverse effects	Measured by questions assessing whether participants encountered any adverse effects of treatment, developed any new psychological symptoms, or experienced any unexpected events over the course of treatment	9 weeks following baseline
Secondary	Service utilization	Measured by a series of questions asking participants whether they accessed additional services or support	Weeks 9, 13, and 37
