# Efficacy and acceptability of a blended intervention for emotion regulation (MAISHA) among young people in Kenya: study protocol for a cluster RCT

## TL;DR

This study tests a blended mental health intervention called MAISHA to improve emotion regulation in Kenyan youth through a randomized trial.

## Contribution

The study introduces a youth-co-designed blended intervention for emotion regulation in low-middle income countries.

## Key findings

- The trial will assess the efficacy of a blended intervention versus care as usual on emotion regulation difficulties.
- It includes a factorial design comparing digital-only, face-to-face-only, and blended approaches.
- The study emphasizes participatory approaches in mental health interventions for adolescents in LMICs.

## Abstract

Adolescence is a crucial developmental period characterized by increased challenges in emotion regulation, a key mechanism linked to mental health. In Kenya, one in every two adolescents and youth faces a mental health challenge, highlighting a need for early interventions targeting emotion regulation. This study will evaluate the efficacy and acceptability of MAISHA, a blended indicated mental health intervention co-designed with young people to strengthen emotion regulation among those experiencing related difficulties.

In a parallel group, cluster-randomized 2 × 2 factorial controlled trial, 666 young people aged 13–25 will be randomly allocated to one of four 4-week study arms at a ratio of 1:1:1:1. (1) digital app blended with a face-to-face element; (2) digital app only; (3) face-to-face element only; or (4) care as usual (CAU). The digital app will build on an ecological momentary intervention. The face-to-face element will consist of four group sessions on growth mindset, values, and gratitude. The primary outcome is emotion regulation difficulties, assessed post-intervention using the short form of the Difficulties in Emotion Regulation Scale (DERS-SF), and comparing the blended intervention (digital and face-to-face) to CAU. Secondary measures include emotional reactivity, emotional distress, positive and negative affect, acceptability, desirability, safety, and usability. The trial will include an embedded micro-randomized trial and a process evaluation.

This trial advances adolescent global mental health by strengthening evidence on youth-focused, mechanism-informed, blended interventions while also highlighting participatory approaches in LMICs.

The trial was registered in the Pan African Clinical Trials Registry on July 17th, 2025, as PACTR202507903096871 (https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=34896).
