Cannabis, Pregnancy

Brief summary

This study will recruit 20 women who are high risk for prenatal cannabis use for a 12-week program of using the tracker and receiving a Lifestyle Physical Activity program. The primary outcomes will be self reported percent days of cannabis use and physical activity. Secondary outcomes include self -reported measures of depression and anxiety symptoms, adaptive coping, and self-efficacy for cannabis abstinence.

Detailed description

This study will recruit 20 women in an open trial who are high risk for prenatal cannabis use for a 12-week program of using a Fitbit activity tracker and receiving a Lifestyle Physical Activity program. The primary outcomes will be self reported percent days of cannabis use and physical activity. Secondary outcomes include self -reported measures of depression and anxiety symptoms, adaptive coping, and self-efficacy for cannabis abstinence. The investigators will clinically monitor all participants in the study for safety and clinical deterioration, and measure a variety of symptom outcomes over the course of the intervention period during pregnancy, as well as at a postpartum follow-up.

Interventions

BEHAVIORALLPA + Fitbit Intervention

Participants will receive a Fitbit to track activity levels and participate in a 6-session lifestyle physical activity intervention over the course of 12 weeks. The intervention consists of 20-25 minute phone or video-delivered session to: (a) review PA progress and re-evaluate current step-count goals, (b) problem-solve barriers to incorporating PA into their daily lives, (c) address difficulties utilizing the Fitbit, (d) encourage the use of bouts of PA as a coping strategy, and e) engage the participant in brief discussions focused on increasing and maintaining PA.

Design outcomes

Primary

MeasureTime frameDescription
International Physical Activity Questionnaire (IPAQ) Walked 10+ Continuous Min/DayBaseline to 12-week endpointNumber who reported walking 4 or more days/week for 10 or more continuous minutes per day
Number of Participants Using Cannabisfrom week 6 to the end of the intervention at week 12Number of participants using cannabis at week 12, assessed via the Timeline Follow Back
Steps/DayBaseline to 12-week endpointobjectively-measured via wearable device

Secondary

MeasureTime frameDescription
Edinburgh Postnatal Depression Screenpast week, assessed at week 12 (end of intervention)Self-report measure of depression severity; scores range from 0-30, with higher scores indicating more severe depression
Generalized Anxiety Disorder -7past 2 weeks, assessed at week 12 (end of intervention)Self-report measure of anxiety severity; scores range from 0-21, with higher scoring indicating more severe anxiety
Client Satisfaction Questionnaire (CSQ-8)Week 12 End of Treatment (EOT)The Client Satisfaction Questionnaire is an 8 item survey of participant satisfaction. Scores range from 8-32; higher scores indicate higher satisfaction.

Participant flow

Recruitment details

This study used wide-scale community recruitment to reach a number of sites serving perinatal women, including OB/GYN, primary care and behavioral health settings, as well as community based advertising online (e.g. hospital website, social media such as Facebook) and in-person community fliers. All potential participants were screened by phone.

Pre-assignment details

Because this was an Open Trial, all eligible participants were assigned to the lifestyle physical activity intervention. Please note that this study was funded as part of an NIH R34 award that involved 2 different studies. The current project reported here (NCTNCT05528380) was an open pilot trial; in addition, there was a second study funded by the R34, which was a pilot randomized controlled trial (RCT). The pilot RCT study was designated a separate NCT entry (NCT06239701).
