| 요약 | Background. Most U.S. adolescents ages 13 to 17 use smartphones, so there is tremendous potential to use smartphones to deliver health interventions to adolescents. A health app's acceptability is an important precursor of usage. However, no validated measures of health app acceptability among adolescents currently exist. Therefore, I aimed to develop and validate a scale to measure the acceptability of health apps among adolescents.Methods. In Study 1, I conducted interviews with participants (n = 19) in grades 7-9 to understand how adolescents assess health app acceptability. In Study 2, I developed an acceptability scale based on the Theoretical Framework of Acceptability, administered it to participants (n = 182) testing the Fooducate app, and revised the scale after analyzing the psychometric properties and conducting exploratory factor analysis. In Study 3, a new participant sample (n = 161) tested the Fooducate app and completed surveys that included the revised acceptability scale items. One week later, I collected data from participants' phones about their Fooducate usage. I conducted confirmatory factor analysis and used structural equation modeling to assess the relationship between acceptability and Fooducate usage.Results. I developed and tested the 22-item Acceptability of Health Apps among Adolescents (AHAA) scale that measured six domains of acceptability: affective attitude, burden, ethicality, intervention coherence, perceived effectiveness, and self-efficacy. The scale had high internal consistency (慣 = 0.91) and consisted of six reliable subscales (慣's ranging from 0.77 to 0.90). EFA results indicated that the 22-item scale had a six-factor structure. With a separate sample of participants, I used CFA and confirmed that all six subscales were unidimensional and that the 22-item scale had the predicted six-factor structure. However, CFA did not confirm a higher order latent factor model for acceptability. Ethicality (棺 = 0.018, p < 0.05) and self-efficacy (棺 = 5.16, p < 0.05) predicted usage after one week.Conclusion. The 22-item AHAA scale and subscales are reliable and CFA results confirm the expected six-factor structure. In addition, ethicality and self-efficacy predicted health app usage among adolescents and are important aspects of acceptability for this population. Additional research is needed to further assess the validity of the scale across different adolescent populations and with various health apps. |
