Effectiveness of an eHealth intervention to improve subjective well‐being and self‐efficacy in cardiovascular disaease patients: A pilot non‐randomized controlled trial

Aim To evaluate the effectiveness of a multicomponent, eHealth‐based self‐efficacy intervention to promote subjective well‐being and self‐efficacy in patients with cardiovascular disease, exploring sex differences. Design A pilot study of a two‐arm non‐randomized controlled trial. Methods Forty‐two cardiovascular patients (31% women) participated in the study. The experimental group received a personalized psychoeducational session and a 14‐days eHealth intervention. Subjective well‐being (positive and negative affect) and self‐efficacy (chronic and cardiac) were assessed at baseline, post‐psychoeducational session, post‐eHealth intervention and at two follow‐ups. Results The levels of the experimental group in positive affect, at post‐eHealth and follow‐up 1, and self‐efficacy, at post‐eHealth, and both follow‐ups, were statistically significantly higher compared to the control group (all ps
