Factors Predicting Ineffective Contraception Use

This is a randomized controlled trial with one intervention group (peer-specialist led telephone-based CBT) and an observation only control group. There will be 3 measurement periods: baseline (pre-intervention), 10-week follow-up (post-intervention) and 14-week follow up. The 14-week follow up assesses the primary outcome (consistency of contraception use) and secondary outcomes (psychological symptoms and self-esteem), whereas the 10-week follow up assesses mediating variables (sexual self-efficacy, contraceptive self-efficacy, social support and coping). There is also a 4-week, mid-intervention assessment of outcomes designed to assess if there is a worsening of symptoms that needs to be addressed (e.g. referral for spike in depression or emergence of suicidal intent). This midterm evaluation also allows us to monitor the well-being of the control group, which has significantly less contact with project staff than the intervention group.

We will recruit 132 sexually active women from health care clinics (e.g., family planning, OB/GYN), with the aim of retaining at least 92 (46 per condition). Interested women will be consented and screened for eligibility in a private area of the clinics. They will be contacted by phone after consent to complete a structured, baseline questionnaire. After the baseline questionnaire, women will be randomly allocated to study conditions. Women will be randomized based on the randomization schedule established by the project biostatistician. Women allocated to the CBT intervention group will be mailed an intervention workbook and have their first telephone-based intervention session scheduled. The CBT intervention group will receive 8 telephone-based CBT intervention sessions (over 9 weeks) delivered by peer specialists. Each session will last up to 30 minutes. The control group will be an observation only control group (CTL group). They will not receive any intervention. The post-intervention and 1-month follow up questionnaires will also be collected via structured telephone interviews. Research staff who are collecting data will be blinded to study condition.

In addition to monitoring for worsening of psychological symptoms, procedures are in place for referring participants with worrisome increases in depression (i.e., >14 on the PHQ9) or suicidal intent to relevant mental health resources, including hospital emergency rooms and suicide hotlines for persons expressing suicidal intent. Further, the DSMB will be alerted so that they can monitor whether one condition appears to have an unusually high increase in symptoms, which might warrant stopping the trial for safety reasons. In addition, the researchers collecting data and the peer-specialists implementing the intervention will be engaged in weekly supervision with a clinical psychologist and have access to the study PI at all times. The project biostatistician will conduct all intention-to-treat (ITT) analyses using appropriate modern statistical approaches.
