Brief Summary

The proposed research involves the running of a feasibility trial to assess a smart phone app designed to support military veterans (as they transition out of the Armed Forces) experiencing mental health difficulties to monitor and manage their mental health, encouraging them to seek formal mental healthcare services if required. The trial will compare participants who are provided with the 'full' app (case group) with participants who receive a 'signposting only' feature free smartphone app, receiving the 'full' app 3months later once the research trial is over (control group).

The feasibility trial has two core aims:

1. To provide initial assessment of the practicality of testing the app Running of the feasibility trial will provide key information on the practical delivery of the app and measurement processes; enable an estimation of recruitment and retention of participants; as well as trialling a series of outcome measures. All participants taking part in the trial will be asked to complete a short (20minute) in app survey at three time points: baseline; baseline plus 1month; baseline plus 3months. This questionnaire will collect demographic information and employ a number of well-being and quality of life measures.

2. To provide initial feedback on the app The trial will qualitatively evaluate how those in the case group use the 'full' app (via collection of app usage data over a 1month trial period) and how easy to interact with, and potentially helpful, they consider the app might be (via a short 30minute telephone interview at the end of the 1month app trial period).

If the trial indicates that the app is acceptable and feasible then a full randomized control trial (subject to funding) will be run to assess the effectiveness of the app in supporting mental health. If proven acceptable then the app would be made freely available to all.

Detailed Description

In line with the Medical Research Council Complex Intervention Framework (Medical Research Council) the feasibility stage of developing an intervention is focused on three areas to assess the practical aspects of testing an intervention including:

* Testing procedures (technical app delivery; measurement processes)

* Estimating recruitment and retention (number of eligible/ interested participants; drop-out rates)

* Determining sample size (testing main outcome measures to determine appropriate sample size for a later randomised control trial)

In addition to this, the feasibility trial will provide feedback from participants on their reactions to the app including:

* Actual use of the app

* Satisfaction with the app

* How appropriate they believe the app to be

* Intent for continued use

This toolkit will provide those who participate in the research with an additional support tool which may help them to manage their own mental health during a potentially challenging period (as they transition out of the Armed Forces) and help them to identify a need for more formal support if required.

Primary Outcome Measures
NameTimeMethod
Trial procedures and outcome measures: GHQ12Baseline plus 3 months (84 days)

The General Health Questionnaire (GHQ-12) is a measure of common mental disorders such as anxiety and depression. It is a 12-item self-report questionnaire measured on a 4-point scale. Scores range from 0-12 with a score of 4 or more indicative of probable mental ill health.The difference between scores at baseline, day 28 (1month) and day 84 (3months) were calculated.

Trial procedures and outcome measures: PCL-CBaseline plus 3 months (84 days)

To evaluate symptoms of PTSD, the PTSD Checklist Civilian version (PCL-C) was used. It is a 17-item self-report questionnaire, measured on a 5-point scale from (1) not at all to (5) extremely. Scores range from 17 to 85, scores over 50 are indicative of possible PTSD. The difference between scores at baseline, day 28 (1month) and day 84 (3months) were calculated.

Trial procedures and outcome measures: WHO QOL-BREFBaseline plus 3 months (84 days)

Quality of life was assessed using the World Health Organization Quality of Life Assessment (WHOQOL-BREF), a 26-item self-report questionnaire divided into four domains: physical health; social relationships; psychological health; environmental health. It is measured on a 5-point scale, with a score of 0-100 calculated, where 100 equates to the best possible state of health. The difference between scores at baseline, day 28 (1month) and day 84 (3months) were calculated.

Acceptability and usability: UsageBaseline plus 1 month (28 days), end of initial trial period

App usage data were collected from Google Analytics via Firebase (CA, USA) and included information such as the number of times the app was opened, the duration of each app use and the number of times specific sections of the app were used.

Recruitment and retention: Response rate5month recruitment period

Calculate the total number of eligible participants who went onto complete the consent form. Calculate this as a percentage of total number of eligible participants.

Recruitment and retention: One month follow up retention ratesBaseline plus 1 months (28 days), end of trial period

Calculate the total number of participants enrolled onto the study who went onto complete the 1month follow up. Calculate this as a percentage of total number of enrolled participants.

Recruitment and retention: Number of interested participants5month recruitment period

Calculate the total number of participants contacting the study team to express an interest in taking part in the study.

Recruitment and retention: Number of eligible participants5month recruitment period

Calculate the total number of participants contacting the study team to express an interest in taking part in the study who are eligible to take part. Calculate this as a percentage of total number of interested participants.

Recruitment and retention 5: Comparability of sample to MOD personnelBaseline plus 3 months (84 days)

Comparability of sample to Ministry of Defence statistics for major sub-groups of veterans (age, service branch, rank)

Trial procedures and outcome measures: Technical deliveryBaseline plus 1 months (28 days), end of trial period

Evaluation of the technical delivery of the app was gained through gathering feedback from developers and participants, identifying any potential technical issues

Acceptability and usability: MAUQBaseline plus 1 month (28 days), end of initial trial period

The mHealth App Usability Questionnaire (MAUQ) was used to assess app usability at day 28. A 16 item version of the MAUQ of the self-report questionnaire was used, measured on a 7-point scale ranging from strongly disagree (1) to strongly agree (7). Participant responses were aggregated into overall usability and three other domains: ease of use and satisfaction, interface and functionality, and usefulness. The mean total score and the mean of each three domains were scored out of seven, with a score of four indicating a neutral response and higher scores indicating greater app usability.

Recruitment and retention 4: Three month follow up retention ratesBaseline plus 3 months (84 days)

Calculate the total number of participants enrolled onto the study who went onto complete the 3month follow up. Calculate this as a percentage of total number of enrolled participants.

Trial procedures and outcome measures: Well-beingBaseline plus 3 months (84 days)

Warwick Edinburgh Mental Well-being Scale (WEMWBS) measures mental well-being within the previous two weeks and is a 14-item self-report questionnaire measured on a 5-point scale from (1) none of the time to (5) all of the time. Scores range from 14 to 70 with higher scores indicative of greater mental well being. The difference between scores at baseline, day 28 (1month) and day 84 (3months) were calculated.

Trial procedures and outcome measures: Completion ratesBaseline plus 3 months (84 days)

Examination of the feasibility of using the app to collection outcome measures was assessed via completion rates for each of the questionnaires (baseline; 1month follow up; 3month follow up)

Trial procedures and outcome measures: Sample sizeBaseline plus 3 months (84 days)

Sample size estimates for a future randomised control trial were assessed via changes in GHQ12 scores from baseline to 3month follow up.
