Assessment of content, behavior change techniques, and quality of unintended pregnancy apps in Spain: Systematic search on app stores

OBJECTIVE: Unintended pregnancies are a public health problem that represents 48% of global pregnancies. Despite the proliferation of smartphones there is limited data on the app's features on unintended pregnancy. The purpose of this research was to identify free apps available in Spanish, in the iOS Store and Google Play, which can be recommended to prevent unintended pregnancies in adolescents. METHODS: A systematic search to identify apps was performed in the iOS App Store and in Google Play aiming to replicate the way a patient might access an “unintended pregnancy prevention” app. Additionally, the quality, using the Mobile Application Rating Scale, and content were assessed. RESULTS: A total of 4614 apps were identified, of which 8 were retrieved for assessment (0.17%). The mean for objective and subject quality was 3.39 (standard deviation (SD) = 0.694) and 1.84 (SD = 0.626), respectively. A total of 16 thematic categories were identified. The mean of topics covered in the apps was 5.38 (SD = 2.925) being those related to contraception the more frequent. CONCLUSION: The results of the present study suggest that only a small percentage of free pregnancy prevention apps in Spanish should be recommended. The contents of the apps retrieved meet the potential necessities of adolescents.
