摘要

Research to identify predictors of e-mental health response could guide the development of novel, targeted interventions. This study used data from a North American open label trial of a smartphone-based mental health app (MindShift, Anxiety Canada) to examine (i) the concurrent, baseline association of self-efficacy difficulties and helplessness with anxiety and depressive symptoms, functional impairment, and quality of life; (ii) change in self-efficacy difficulties or helplessness over time; and (iii) if self-efficacy difficulties or helplessness predict change in well-being over time. Adults (N = 154) ages 18 to 74 in Canada and the USA reported on self-efficacy difficulties and helplessness at baseline and after 8- and 16-weeks of using the MindShift app. Participants also reported on quality of life, functional impairment, anxiety symptoms, and depressive symptoms at baseline and after 2-, 4-, 8-, 12-, and 16-weeks of app use. Greater baseline distress (i.e., higher symptomatology) correlated with self-efficacy difficulties and helplessness. Over the 16 weeks of app use, self-efficacy difficulties, helplessness, and clinical outcomes improved. Linear change over time in each outcome varied between participants but not as a function of participants’ baseline self-efficacy or helplessness. Although self-efficacy difficulties and helplessness improved among adults using the MindShift app, baseline levels of these factors did not predict improvement in clinical outcomes.
