Development of a culturally informed protocol for hair cortisol sampling in Black women

This article describes the development of a culturally informed hair collection protocol for cortisol research with Black women. We first conducted a formative research study investigating the acceptability of hair cortisol sampling for African-American college women, where acceptance reached 54%. Findings, including the reasons reported for participation, were then used to develop a culturally informed hair sampling protocol for two studies in a community setting where acceptance improved to 75%. Specific barriers to hair sampling for research in this population were supported. Recommendations to increase participation in hair sampling are provided.
