Apps using digital photos to track dietary intake and provide feedback are common, but currently there has been no research examining what evidence-based strategies are included in these apps.
A content analysis of mobile apps for photo diet tracking was conducted, including whether effective techniques for interventions promoting behavior change, including self-regulation, for healthy eating (HE) are targeted. An initial search of app stores yielded 34 apps (n = 8 Android and Apple; n = 11 Android; n = 15 Apple). One app was removed (unable to download), and other apps (n = 4) were unable to be rated (no longer available). Remaining apps (n = 29) were downloaded, reviewed, and coded by 2 independent reviewers to determine the number of known effective self-regulation and other behavior change techniques included. The raters met to compare their coding of the apps, calculate interrater agreement, resolve any discrepancies, and come to a consensus.
Six apps (21%) did not utilize any of the behavior change techniques examined. Three apps (10%) provided feedback to users via crowdsourcing or collective feedback from other users and professionals, 7 apps (24%) used crowdsourcing or collective feedback, 1 app (3%) used professionals, and 18 apps (62%) did not provide any dietary feedback to users.
Few photo diet-tracking apps include evidence-based strategies to improve dietary intake. Use of photos to self-monitor dietary intake and receive feedback has the potential to reduce user burden for self-monitoring, yet photo diet tracking apps need to incorporate known effective behavior strategies for HE, including self-regulation.
利用数码照片追踪饮食摄入并提供反馈的应用程序很常见，但目前尚无研究考察这些应用程序中包含哪些循证策略。
对用于照片饮食追踪的移动应用程序进行了内容分析，包括是否针对促进行为改变（包括自我调节）以实现健康饮食（HE）的有效干预技术。对应用商店的初步搜索产生了34个应用程序（n = 8个安卓和苹果系统；n = 11个安卓系统；n = 15个苹果系统）。移除了一个应用程序（无法下载），其他应用程序（n = 4）无法评级（不再可用）。由2名独立评审员下载、审查并编码剩余的应用程序（n = 29），以确定其中包含的已知有效自我调节和其他行为改变技术的数量。评审员会面比较他们对应用程序的编码，计算评分者间一致性，解决任何差异，并达成共识。
6个应用程序（21%）未使用任何所考察的行为改变技术。3个应用程序（10%）通过众包或其他用户及专业人员的集体反馈向用户提供反馈，7个应用程序（24%）使用众包或集体反馈，1个应用程序（3%）使用专业人员，18个应用程序（62%）未向用户提供任何饮食反馈。
很少有照片饮食追踪应用程序包含改善饮食摄入的循证策略。利用照片进行饮食摄入自我监测并获得反馈有可能减轻用户自我监测的负担，但照片饮食追踪应用程序需要纳入已知有效的健康饮食行为策略，包括自我调节。
