Plain English summary of protocol
Background and study aims
Exposure to the natural environment is increasingly thought to benefit psychological health. Recent reports also suggest that outdoor activities that include recreational pursuits (such as surfing or fishing) coupled with the opportunity to socialize with others in similar circumstances may be helpful to military veterans experiencing Post-Traumatic Stress Disorder (PTSD). This study will evaluate this possibility.
Who can participate?
Military veterans with a diagnosis of post-traumatic stress disorder
What does the study involve?
Veterans with PTSD will be allocated to either an active outdoor recreational pursuit (angling) or a waitlist control group (this group will receive the intervention at a later date). We will measure changes to their symptoms (PTSD, depression, anxiety and other aspects of well-being) 2 weeks before the intervention, 2 weeks after the intervention for both groups; The waitlist participants will be also be reassessed two weeks after they subsequently completed the intervention and both groups will be followed up 4 months post-intervention.
What are the possible benefits and risks of participating?
The participants for this study are military veterans with PTSD and other anxiety-related issues. They, therefore, have mental health problems but this is a defining aspect of the study and cannot be undertaken with participants without these issues. It is not thought there are any risks in this study above and beyond those normally encountered in everyday life.
It is thought that exposure to an outdoor recreational experience will be beneficial in terms of decreased anxiety, depression and PTSD-symptoms and increased well-being.

| Scientific title | Examining the effects of outdoor recreational experiences on the mental health and well-being of military veterans with post-traumatic stress disorder (PTSD): a randomized controlled trial |
| Study objectives | It is hypothesized that participants in the intervention group will experience a reduction in PTSD-related symptomology and an increase in subjective well-being relative to participants in a wait list control group, as a consequence of a short, outdoor, recreational activity. |
| Ethics approval(s) | Approved 28/08/2014, the University of Essex Ethics Committee (Science & Health Ethics Sub-Committee, University of Essex, Wivenhoe Park, CO4 3SQ; reo-governance@essex.ac.uk; +44 (0)1206 87356), ref: NC1408 |
| Health condition(s) or problem(s) studied | Post-traumatic stress disorder (PTSD) |
| Intervention | The intervention is designed to deliver an outdoor recreational activity (fishing) in a peer group context and to facilitate opportunities to socialize and to discuss military experience or PTSD experience if the participant so wishes. The intervention lasts 2 days (1 night) and will take place at a rural, lakeside location. Participants will be randomly allocated to one of the two levels of the between-groups factor (to either active intervention or waitlist control). They will be sequentially numbered and allocated to condition by means of an online blocked randomization tool. Each participant will complete questionnaires to assess their PTSD, depression, anxiety, and stress. The intervention group participants will be given these at 2 weeks before they receive the intervention, at 2 weeks following the intervention. The waitlist participants will be also be assessed at baseline and four weeks later. The waitlist group will also be reassessed two weeks after they subsequently completed the intervention. Both groups will be followed up 4 months post-intervention. |
| Intervention type | Behavioural |
| Primary outcome measure | 1. PTSD symptoms assessed by the PCL-5 at baseline, 2 weeks and 4 months 2. Depression assessed by the Patient Health Questionnaire (PHQ-9) at baseline, 2 weeks and 4 months 3. Anxiety assessed by the General Anxiety Disorder (GAD-7) at baseline, 2 weeks and 4 months |
| Secondary outcome measures | 1. Perceived stress assessed by the 10-item Perceived Stress Scale (PSS) at baseline, 2 weeks and 4 months 2. General social functioning assessed by the Work and Social Adjustment scale (WSAS) at baseline, 2 weeks and 4 months 3. Positive change in psychological growth assessed by the Psychological Wellbeing Post-Traumatic Changes Questionnaire (PWB-PTCQ) at baseline, 2 weeks and 4 months |
