To explore patients' use of the self-monitoring app Recovery Record during 26 weeks of naturalistic eating disorder treatment.
Selected patient characteristics at baseline were explored as predictors of app use using linear regression. Patients were grouped according to diagnosis (anorexia versus bulimia), and mixed-effects analyses were used to explore differences in app use between diagnoses across four time periods (weeks 1-4; weeks 5-8; weeks 9-12; weeks 13-26).
Eighty-four patients were included of which 41 had anorexia and 43 had bulimia. The total number of logs varied greatly (mean (SD): 592 (628.50)), and patient app activity almost ceased at week 13. Increasing age and no previous eating disorder treatment predicted increased app activity (p = .007; p = .039, respectively). Patients with anorexia logged over four times more often than patients with bulimia in the last time period (median (CI): 4.27 (1.28;14.31); p = .018). Time predicted declining app use (all p ≤ .007).
Future research on long-term app engagement should investigate associations between patients' app use and changes in their eating disorder symptom severity over time.
探索患者在自然主义进食障碍治疗的 26 周内使用自我监测应用程序 Recovery Record 的情况。
使用线性回归分析了基线时选择的患者特征，以预测应用程序的使用情况。根据诊断（厌食症与贪食症）对患者进行分组，并使用混合效应分析比较了两种诊断之间在四个时间段（第 1-4 周；第 5-8 周；第 9-12 周；第 13-26 周）的应用程序使用差异。
共纳入 84 名患者，其中 41 名患有厌食症，43 名患有贪食症。记录的日志总数差异很大（均值（SD）：592（628.50）），且患者的应用程序活动几乎在第 13 周停止。年龄增长和无既往进食障碍治疗史预测了应用程序活动的增加（p=.007；p=.039）。在最后一个时间段，厌食症患者的记录次数是贪食症患者的四倍多（中位数（CI）：4.27（1.28；14.31）；p=.018）。时间预测了应用程序使用的下降（所有 p 值均≤.007）。
未来关于长期应用程序参与度的研究应调查患者应用程序使用情况与随时间推移其进食障碍症状严重程度变化之间的关联。
