Brief Summary

Anxiety and worry are amongst the most common mental health difficulties. The Second Mental Health Study found a significant increase in the lifetime prevalence for GAD, from 0.9% to 1.6%. In addition, the Organisation for Economic Cooperation and Development found that among Singaporean students, 86% experienced anxiety levels that were significantly higher than the OECD average.

Past research revealed that individuals who worried more experienced decreases in life satisfaction. It was also found that worry and anxiety are significant predictors of one's psychological wellbeing .

In line with this trend, the market for wellbeing apps have been one of the fastest growing categories of apps ever since; with more than 10,000 on the market. Studies have shown that the use of wellbeing apps has been correlated with an improvement in mental wellbeing. However, due to the lack of research that focuses on disorder-specific evidence, there still exists debates around the effectiveness of wellbeing apps on anxiety and worry. In addition, the lack of research on the mediating factor of psychological mindedness in the relationship between the use of wellbeing apps and mental well-being, could be pivotal to the effectiveness of wellbeing apps.

To show the effectiveness of evidence-based wellbeing apps in targeting anxiety and worry, this study will employ the engagement of participants with a wellbeing app for a controlled period of 2 weeks before recording their mental wellbeing outcomes.This paradigm has been replicated extensively through multiple studies.

This study will use a between-groups experimental study design whereby participants will be block randomised into 2 conditions: Active control condition, and Anxiety condition. Each condition will be given a restricted version of the wellbeing app according to their treatment groups. Follow-up data will be collected at 2-weeks post intervention to establish efficacy of the intervention.

Objective 1: To evaluate the effectiveness of a wellbeing app self-help programme for reducing anxiety and worry.

Objective 2: To examine if psychological mindedness moderates hypothesised effects of wellbeing app usage and anxiety and worry.

Hypothesis 1: Participants in the intervention group will report significantly lower anxiety and worry than participants in the control group.

Hypothesis 2: Psychological mindedness will moderate the effect of the wellbeing app's self-help programme on anxiety and worry: Participants high in psychological mindedness will benefit more from the wellbeing apps than those with lower scores on psychological mindedness.

Primary Outcome Measures
NameTimeMethod
Patient Health Questionnaire - 9 (PHQ-9)2 weeks after the completion of the intervention

Patient Health Questionnaire (PHQ-9) i s a 9 item self report instrument that measures depression. Items are scored on a 4-point scale, ranging from "not at all (0)", "several days (1)", "more than half the days (2)" and "nearly everyday (3)". In a sample of 3000 patients in the PHQ Primary Care Study, PHQ-9 achieved an excellent internal consistency of α=0.89 (Kroenke, Spitzer, \& Williams, 2001).

General Anxiety Disorder - 7 (GAD-7)2 weeks after the completion of the intervention

General Anxiety Disorder- 7 (GAD-7) is a 7 item self report instrument that measures anxiety and is widely used in research in clinical and nonclinical practices anxiety as a continuum (Siddaway, Taylor \& Wood, 2018) and is a reliable and valid instrument for assessing anxiety in a general population (Löwe et al., 2008). Items are scored on a 4-point scale, ranging from "not at all (0)", "several days (1)", "more than half the days (2)" and "nearly everyday (3)". GAD-7 produced an excellent internal consistency of α=0.92 in a sample of 2982 participants (Spitzer, Kroenke, Williams, \& Löwe, 2006).

Secondary Outcome Measures
NameTimeMethod
Psychological Mindedness ScaleMeasured before the intervention

Psychological Mindedness Scale (PM): 45 item self report instrument that measures an individual's ability to be reflective about interpersonal relationships, psychological processes and meanings across both intellectual and emotional dimensions. Items are scored on a 4 point-scale ranging from "strongly agree (4)" to "strongly disagree (1)". The PM has a good internal consistency of α= 0.86 and recomputed to 0.87 in a study of 256 patients (Conte et al., 1990).

App Engagement ScaleMeasured 1-2 days after completing the intervention (2 weeks)

App Engagement Scale (AES): 7 item self report feedback instrument that indicates the degree to which an individual engages with an app. Items are scored on a 5 point-scale ranging from "strongly agree (5)" to "strongly disagree (1)". This App Engagement Scale had good internal reliability, Cronbach's α = .839 in a study of 1349 app user (Rickard \& Bakker, 2019).
