Brief Summary

Depression in pregnancy is common, affecting up to 10% of women and represents serious risk to mother and infant. Unfortunately, antidepressant medication, a first-line treatment for depression in pregnancy, also comes with risks, making this a complex decision. Clinical care appears to be insufficient for ensuring that women make decisions that are consistent with their own values and with which they feel satisfied. Patient decision support tools can address such barriers. We have created and piloted with positive results an online patient decision aid (PDA) that has the potential to improve the decision-making process for women regarding antidepressant use in pregnancy in conjunction with clinical care. The overall objective of this study is to conduct a Randomized Controlled Trial (RCT) to assess the efficacy of our PDA for antidepressant use in pregnancy.

Detailed Description

A parallel group randomized controlled trial (RCT) will be conducted. Eligible and consenting women with depression will be randomized in a 1:1 ratio to either online PDA or a control condition comprising an online set of publicly available standard resources. The study will be stratified by preconception vs. pregnant, and by province.

The study is based at Women's College Hospital (Toronto) but participants will be recruited from across Canada, as the online intervention does not require any in-person study visits. Participants will be recruited via social media (ex. Facebook, Twitter, mommy/baby blogs) and by provider referrals.

Participants will be given a series of online questionnaires with various measures collected at baseline, 4 weeks post-randomization, in each trimester of pregnancy, and at 1, 3, 6 and 12 months postpartum. Participants who are planning pregnancy will enter the longer-term (pregnancy and postpartum) follow-up phase once they become pregnant; those who do not conceive by one year post-randomization will be sent a final set of questionnaires and exit the study. A process evaluation will also be conducted to gain insights around trial conduct, and perspectives on potential for (or barriers to) scale-up. This, along with the planned economic evaluation, will inform clinical and policy decisions around adopting the PDA into real-world practice.

Primary Outcome Measures
NameTimeMethod
Postpartum depression as diagnosed by the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 (SCID-I)3 months postpartum

The depression module will be used to indicate presence of postpartum depression.

Secondary Outcome Measures
NameTimeMethod
Maternal depression as measured by the Edinburgh Postnatal Depression Scale (EPDS)throughout pregnancy and up to 1 year postpartum (up to 21 months)

EPDS is a 10-item self-report scale. Each item is scored 0-3 with scores \>12 being predictive of a diagnosis of depression.

Maternal quality of life as measured by the 12-item Short Form (SF-12) Health Surveythroughout pregnancy and up to 1 year postpartum (up to 21 months)

SF-12 is a 12-item survey used to estimate the quality-adjusted life year (QALY) which incorporates both length of life and quality of life into a single measure. The measure includes a physical component summary and a mental component summary score. It is scored 0-100 with higher scores indicating better physical and mental health.

Health service utilizationthroughout pregnancy and up to 1 year postpartum (up to 21 months)

1) direct medical costs; 2) indirect medical costs; 3) productivity loss due to patient and family work absence

Pregnancy complications and neonatal outcomes1 month postpartum

Self-reported pregnancy complications and neonatal infant characteristics

Study website metrics to inform if patterns of PDA use are predictive of clinical outcomesthroughout pregnancy (up to 9 months)

Data generated by the website to inform how participants interact with the PDA: 1) proportion of participants who login to the PDA; 2) timing from enrollment to first login; 3) total number of PDA logins; 4) number of logins between each study time point; 5) proportion of participants who completed the PDA; 6) timing of enrollment to first completion of PDA; 7) number of logins required prior to first completion of PDA; 8) total number of PDA completions; 9) number of PDA completions between each study time point; 10) mean (SD) number of pages viewed per login; 11) whether or not each page was viewed; 12) whether or not each page was viewed between study time points; 13) whether or not each interactive tag was interacted with; 14) whether each interactive tag was interacted with between study time points

Anxiety disorders as diagnosed by the Structured Clinical Interview for DSM-5 (SCID-I)3 months and 12 months postpartum

The anxiety disorders module will be used.

Feeding and eating disorders as diagnosed by the Structured Clinical Interview for DSM-5 (SCID-I)3 months and 12 months postpartum

The feeding and eating disorders module will be used.

Maternal anxiety as measured by the Spielberger State-Trait Anxiety Inventory (STAI)throughout pregnancy and up to 1 year postpartum (up to 21 months)

STAI is a 40-item self-report scale with good discriminate validity in perinatal populations. Each item is scored 1-4 with scores \>48 being predictive of an anxiety disorder diagnosis.

Postpartum depression as diagnosed by the Structured Clinical Interview for DSM-5 (SCID-I)12 months postpartum

The depression module will be used to indicate presence of postpartum depression.

Decisional conflict as measured by the Decisional Conflict Scale (DCS)throughout pregnancy (up to 9 months)

DCS consists of 16 items each rated 1-5 where scores ≥ 25 represent delayed and ineffective decisions.

Infant Outcomes as measured by the Infant Characteristics Questionnaire (ICQ)3-12 months after birth

ICQ is a 27-item questionnaire with each item scored 1-7. Higher scores indicate higher parental perceptions of difficult infant temperament.

Parenting stress measured by the Parenting Stress Index (PSI) short form1 month postpartum to 1 year postpartum

The PSI-SF is a 36-item measure consisting of 3 subscales (parental distress, dysfunction in parent-child relations, difficult child). Each item is scored 1-5 with higher scores indicating higher levels of parenting stress. PSI reports subscales separately and also reports a total measure.
