Feasibility and acceptability of texting school-aged adolescents to assess daily substance use among community-based black and white youth

Background: Ecological momentary assessment (EMA) is well-suited to measure adolescent substance use. Previous research with adolescents, particularly racially minoritized adolescents, has predominantly provided mobile devices to participants as a strategy to reduce structural barriers to technology access. This report examined feasibility and acceptability of a text-message-delivered EMA protocol to adolescents' personal phones.Methods: Non-Hispanic Black and White adolescents aged 14-18 years with mobile phone access and past-30-day substance use were recruited from community settings. Respondents (n = 36; 55.5 % female; 55.5 % White) completed a 14-day diary assessing substance use.Results: Respondents completed M = 13.8 (SD = 1.36) diaries for a compliance rate of 93.5 %. Black respondents completed significantly fewer diaries (87.9 %) than White respondents (97.9 %) although compliance rates were high among both groups. Adolescents reported high acceptability of the protocol, with 97.1 % willing to participate again.Conclusion: Findings suggest text-message-based EMA delivered to personal phones is acceptable and feasible for assessing substance use among adolescents. As the sociodemographic "digital divide" narrows among adolescents, this cost-effective and equitable method becomes more feasible.
