# Willingness of pregnant and postpartum women who use marijuana and/or cannabidiol to participate with their offspring in long-term cohort studies: an exploratory study

## TL;DR

Pregnant and postpartum women using marijuana or cannabidiol are willing to join long-term studies if trust is built and data privacy is ensured.

## Contribution

Identifies specific factors influencing participation willingness in long-term cohort studies among marijuana/cannabinoid-exposed women.

## Key findings

- Participants emphasized the need for trust and anonymity to avoid negative consequences.
- Detailed transparency about data collection and usage was requested before consent.
- Incentives were seen as important for participation and retention.

## Abstract

Prevalence of marijuana and cannabinoid use is increasing among reproductive-age women. There are uncertainties regarding long-term impacts of marijuana and/or cannabinoid exposure among pregnant women and their offspring. Longitudinal cohort studies of marijuana and/or cannabinoid exposed mother-infant dyads is the best way to ascertain the long-term impacts. However, previous studies have shown enrollment, and long-term retention are challenging in substance-exposed women.

This study explores the willingness of pregnant and postpartum women who use marijuana and/or cannabidiol to participate with their offspring in long-term cohort studies.

We conducted 4 focus group discussions and one individual one-on-one interview with a total of 17 pregnant or postpartum women using an IRB approved interview guide. All interviews were audiotaped, transcribed and analyzed using the computer assisted qualitative data analysis software Atlas ti™. We used a deductive content analysis approach and utilized consensus coding procedures.

Marijuana and/or cannabinoid-exposed pregnant women are willing to participate in long-term research studies with their babies if they can build a trusting relationship with the research staff and are confident of their anonymity, as protection from negative consequences was a key concern. They would also like to understand in detail what type of data are collected, when and who all will see it and what will be done with the data before they provide the consent. All participants agreed that incentives are important and had various suggestions regarding the type and frequency of incentivization.

The concerns and needs of marijuana and/or cannabinoid-exposed pregnant women recruited for research should be considered carefully in designing study protocols.
