This study evaluates the effectiveness of Stappvoorstap, a mobile self-management application designed for adults on mental health waiting lists in the Netherlands. The app helps users monitor daily stress levels, recognize personal stress patterns, and provides coping strategies, relaxation exercises, and supportive resources. Using a multiple baseline single-case experimental design, participants use the app for 4 weeks while completing weekly questionnaires measuring perceived stress, coping self-efficacy, and quality of life. The study aims to determine whether the app can reduce stress and improve wellbeing during the waiting period before mental healthcare treatment begins.
Prolonged waiting times for mental healthcare pose significant challenges, with nearly 100,000 people on waiting lists in the Netherlands as of December 2023. During this period, symptoms can worsen, daily functioning may decline, and quality of life decreases. Stappvoorstap was developed in co-creation with waitlist clients and experts-by-experience to address this gap. The app is based on stress-signaling plans used in Dutch mental healthcare and functions as an ecological momentary intervention. It measures perceived stress 2-4 times daily, creates visual overviews of stress patterns, and provides real-time coping suggestions, mindfulness exercises, informational articles, and personal stories from other clients. This study uses a nonconcurrent multiple baseline design with A-B-A design. Participants are randomly assigned to 3, 4, or 5-week baseline phases, followed by 4 weeks of app use, and 3 weeks of follow-up. Weekly assessments include the Perceived Stress Scale (PSS-10), Coping Self-Efficacy Scale (CSES-13), and WHOQOL-BREF. Both group-level and individual case analyses will be conducted using mixed-effects modeling and Tau-(BC) effect size measures. Participants are recruited from mental health waiting lists across the Netherlands. As this is a mobile app-based intervention, participation is location-independent and takes place remotely.

RECRUITINGChange in Perceived Stress
Measured using the Perceived Stress Scale with 10 items (PSS-10). The PSS-10 is a validated self-report questionnaire assessing how stressful situations were perceived in the past week. Items are rated on a 5-point scale (1=never to 5=very often). Higher scores indicate higher perceived stress. Change from baseline phase to intervention phase, and to follow-up will be assessed.
Time frame: Weekly measurements for 10-12 weeks (depending on group assignment)
Change in Coping Self-Efficacy
Measured using the Coping Self-Efficacy Scale with 13 items (CSES-13). The CSES-13 measures confidence in coping behaviors across three subscales: problem-focused coping, emotion-focused coping, and social support coping. Items are rated on a 10-point scale (0=cannot do at all to 10=certainly can do). Higher scores indicate greater coping self-efficacy.
Time frame: Weekly measurements for 10-12 weeks (depending on group assignment)
Change in Quality of Life
Measured using selected domains of the World Health Organization Quality of Life Brief version (WHOQOL-BREF): physical health (7 items), psychological health (6 items), and social relationships (3 items), plus 2 items on overall quality of life and general health. Items rated on 5-point Likert scales. Higher scores indicate better quality of life.
Time frame: Weekly measurements for 10-12 weeks (depending on group assignment)
