Starting well to stay well - randomised controlled trial of Whitu, an app for improving the well-being of university students

Abstract

Introduction

University students often face challenges to their well-being and up to a third develop mental health problems. Given high rates of smartphone use among this group, app-based digital mental health interventions may play a role in preventing these problems. Previously demonstrated to improve well-being and mental health outcomes in young people aged 16-25, ‘Whitu: seven ways in seven days’ is a well-being app based on positive psychology, cognitive behaviour therapy (CBT) and psychoeducation principles.

Objectives

This randomised controlled trial was undertaken to evaluate the efficacy, usability and acceptability of Whitu with first year university students.

Methods

Ninety first year university students were recruited via a social media advertising campaign to take part in a prospective randomised controlled trial of Whitu against a standard university self-help website, with 45 participants in each arm. Primary outcomes were changes in well-being on the World Health Organisation 5-item well-being index (WHO-5) and short Warwick-Edinburgh mental well-being escale (SWEMWBS). Secondary outcomes were changes in depression on the Centre for Epidemiological Studies Depression Scale (CES-D), anxiety on the Generalised Anxiety Disorder seven item scale (GAD-7), self-compassion on the Self Compassion Scale- Short Form (SCS-SF), stress on the 10-item Perceived Stress Scale (PSS-10), sleep on the single-item Sleep Quality Scale (SQS), and self-reported acceptability of the app. Outcomes were evaluated at baseline, four weeks (primary study endpoint) and three months.

Results

At 4 weeks, participants in the intervention group experienced significantly higher mental well-being and significantly lower depression compared to controls. Emotional well-being among the Whitu group was greater in the intervention group at 3 months. Other outcomes did not differ between groups. User feedback was positive, with 88% of those who provided feedback saying they would recommend the app to a friend.

Conclusions

Our findings provide preliminary evidence that Whitu is an acceptable and more effective, scalable and multi-modal means of improving some aspects of well-being and mental health among university students than direction to a self-help website.
