Abstract

Depressive symptoms are common, yet only a subgroup of individuals receive adequate treatment. To reduce the treatment gap, several online self-help programs have been developed, yielding small to moderate effects. We developed a smartphone self-help application addressing depressive symptoms. We sought to evaluate its feasibility and efficacy in participants reporting a subjective need for help (a diagnosis of depression was not mandatory). We conducted a randomized controlled trial (N = 90). The primary outcome was a reduction of depressive symptoms measured with the Patient Health Questionnaire-9 (PHQ-9). Secondary outcomes included improved self-esteem (Rosenberg Self-Esteem Scale) and quality of life (WHOQOL-BREF). The intervention group obtained access to the application for four weeks, the wait-list group received access after the post assessment. No group differences emerged in either outcome in intention-to-treat analyses. Per protocol analyses with frequent users (i.e., several times a week or more) yielded a small effect size (η 2p = 0.049) at trend level on the reduction of depressive symptoms in favor of the treatment group. However, 39% of the participants did not use the application frequently. Mobile self-help applications represent a promising addition to existing treatments, but it is important to increase patients' motivation to use them.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
