Internet-Based Psycho-Physical Exercise Intervention Program in Mild-to-Moderate Depression: The Study Protocol of the SONRIE Randomized Controlled Trial

TL;DR

The SONRIE study tests an online program combining exercise and therapy to reduce depression symptoms in adults.

Contribution

This study introduces a novel internet-based combined intervention for mild-to-moderate depression.

Findings

The study protocol outlines a 12-week online intervention with physical exercise and cognitive–behavioral therapy.

Depression severity will be measured using the Beck Depression Inventory at multiple time points.

The trial aims to assess the intervention's impact on depressive symptoms and its potential for clinical use.

Abstract

The COVID-19 pandemic has intensified depression due to isolation and reduced physical activity, highlighting the need for accessible remote treatments. The SONRIE study evaluates the effectiveness of a 12-week online intervention combining physical exercise and internet-based cognitive–behavioral therapy on depressive symptoms in adults with mild-to-moderate depression. This randomized controlled trial involved 80 adults aged 25–65 years diagnosed with depression according to the ICD-10 criteria. Participants were randomized to an experimental group receiving the combined online intervention or to a control group receiving standard care. The primary outcome was the change in depression severity, assessed by the Beck Depression Inventory, with outcomes measured at baseline, immediately post-intervention, and after an 8-week follow-up phase. Statistical analyses include analysis of covariance to compare group changes over time, with effect sizes quantifying the intervention’s impact. The SONRIE study demonstrates a promising online approach for treating depression, with potential implications for clinical practice and public health strategies.
