Demonstration of Smartphones as Viable Tools for Adolescent Substance Use Surveillance

Background: Electronic platform surveys are ideal for self-administration in adolescent populations, as nearly all adolescents in the US report using or having access to smartphones. This technology-savvy population seems prepared to graduate away from paper surveys. Despite predicted advantages of using smartphones for data collection, there is a surprising lack of data regarding the use of this mode for surveillance of substance use trends among adolescent populations. Objectives: The objective of this study was to evaluate completion rates, times, and responses of high school students taking the Secondary Student Life Survey: Nevada (SSLS:NV) on their own personal smartphones compared to provided computers or tablets. Methods: The SSLS:NV is a web-based survey designed to assess adolescent beliefs, attitudes, and use-trends surrounding substance use. The SSLS:NV was self-administered via self-selected device (personal vs. provided) within one class period to approximately one thousand 9th-12th grade students in December 2016. Data was collected and analyzed to compare outcomes by computer, tablet, or smartphone. Statistical analysis was performed in SPSS 23.0 using chi(2) or Fisher's exact test for categorical data and one-way ANOVA for continuous data. Results: SSLS:NV completion times averaged 21 min overall (p = .193). Differences were seen with completion rates of 86% smartphone 94% tablet, and 95% computer (p < .001), while responses to lifetime substance use were similar across all groups. Conclusions/Importance: The current study provides proof of concept that personal smartphones are effective in achieving more comprehensive adolescent substance use surveillance within a relatively short amount of time, while retaining robust response rates.
