Description of intervention(s) / exposure
Acceptance and commitment therapy (ACT) is intended to provide a framework in which coping flexibility, defined as the ability to flexibly choose and implement different coping strategies that fit the needs of the situation (Folkman & Moskowitz, 2004), can be enhanced.
Acceptance and Commitment Therapy targets six interrelated processes in order to enhance the ability to contact the present moment more fully, and to change or persist in behavior when doing so serves valued ends (Hayes, et al., 2006, p. 7).
The six core processes include acceptance (a willingness to experience negative thoughts, feelings and sensations), cognitive defusion (techniques that aim to reduce the literal quality of thoughts), being present (experiencing the world directly as events occur rather than being dominated by mental experiences of the past or future), self-as-context (a standpoint from which one can observe experiences), values (behavioural patterns in domains such as family, career and physical fitness that are intrinsically rewarding (Wilson, Sandoz, Kitchens, & Roberts, 2010)), and committed action (taking effective action linked to values).
The ACT intervention for this study will be delivered by group format, following protocols from previous ACT workplace interventions (Bilich & Ciarrochi, 2009; Bond & Hayes, 2002; Flaxman & Bond, 2006) with additional content from basic coping skills programs (Frydenberg & Brandon, 2007).
It will consist of 3 X 3-hour group sessions, delivered over a 3 month period. The training will be delivered by registered and provisional clinical psychologists.

Summary
Brief summary
Stress is a major issue for police. Officers face a range of stressors related to operational duties, such as exposure to violence and trauma, in addition to a range of organisational stressors. These stressors have been associated with a range of physical and psychological problems, in addition to low morale, absenteeism and increased turnover. They have also been found to impact negatively on an officer’s relationships with family members, friends and colleagues.
The nature of police work means it is not possible to remove all stressors. However, it is possible for police organisations to help develop skills in officers that foster resilience, such that officers are better able to adapt, or bounce back from stress, without experiencing the negative consequences outlined above. Coping refers to thoughts and behaviours that individuals use to deal with stressors. While no single coping strategy has been found to be good or bad in all situations, coping flexibility, the ability to flexibly choose different strategies that fit the needs of the situation has been associated with positive adaptation (Folkman & Moskowitz, 2004).
Studies have found that police have a tendency to use unhelpful, avoidant coping strategies to deal with difficult emotional experiences (Evans, Coman, Stanley, & Burrows, 1993), strategies such as emotional detachment and excessive use of alcohol (Richmond, Wodak, Kehoe, & Heather, 1998). Emotional detachment has been found to undermine the ability of officers to emotional engage and maintain healthy relationships and social networks (Madamba, 1986). Avoidant coping is socialised among new recruits when they are encouraged to take control of situations and not to let their emotions affect their work (Paton, et al., 2009). The primary objectives of the current study is to enhance resilience of police officers by providing training in coping flexibility skills and reducing the use of maladaptive coping skills.
Experiential avoidance, the extent to which individuals: 1) are unwilling to stay in contact with aspects of their private experience; and 2) take steps to alter these experiences (Hayes, Strosahl, & Wilson, 1999) has been found to mediate the effects of maladaptive coping on psychological distress and wellbeing (Fledderus, Bohlmeijer, & Pieterse, 2010) and make people more vulnerable to a range of stressors (Biglan, Hayes, & Pistorello, 2008). As Acceptance and Commitment Therapy (ACT) aims to reduce experiential avoidance, it is thought to be particularly beneficial for preventing severe psychological distress. Furthermore, by enabling officers to persist with valued actions in the face of adversity, ACT is also likely to lift performance and wellbeing.
A range of workplace stress management studies have been conducted using ACT. The current study aims to extend the research of Bilich and Ciarrochi (2009) who conducted a trial of group based acceptance and commitment therapy for senior police officers. The transition from training to active policing environment is a particularly stressful period for new recruits. The current intervention is designed to provide coping skills training to police recruits just before they make the transition to operational duties, and before maladaptive coping strategies have been socialised. Measures of mental health, sick leave and coping strategy use will be used to assess the effectiveness of the training, the sustainability of that effect and measures such as the AAQ, the VLQ and the MAAS will be used to assess mechanisms of change.
