A pilot study for a smartphone app for the prevention of depression in non-professional caregivers.

OBJECTIVES

The main objective of the current study was to evaluate the feasibility and acceptability of a cognitive-behavioral prevention intervention administered through a smartphone app in non-professional caregivers with symptoms of depression. The secondary objective was to make a preliminary evaluation of its effectiveness either alone or supplemented with telephone conference calls.

METHODS

Eighty-seven participants ( = 51.8 years) were randomly assigned to an app-based cognitive-behavioral intervention (CBIA;  = 29), CBIA supplemented with telephone conference calls (CBIA + CC;  = 28), or an attention control group (ACG;  = 30). The participants for both interventions received five cognitive-behavioral modules through the app, and those in CBIA + CC an additional 30-minute phone call in each module.

RESULTS

3.4% of caregivers dropped out. In all groups, the number of modules completed was high. Participants completed a high percentage of the homework and were highly satisfied with both CBIA and CBIA + CC. At post-intervention, there was a lower incidence of depression and depressive symptoms for CBIA + CC compared with CBIA, and for CBIA and CBIA + CC compared with ACG.

CONCLUSION

The results supported the feasibility and acceptability of the cognitive-behavioral intervention, and demonstrated that telephone contact improves its effectiveness.
