SRTS training provides both cognitive learning and training in a scientifically-designed stress resilience training approach designed to minimize the adverse effects of stress and also enhance its positive effects. In summary, the SRTS training comprises: (1) Cognitive rules and mental exercises based on expert knowledge and research; (2) Biofeedback stress control exercises based on proven HRV (Heart Rate Variability) algorithms developed by the Institute of HeartMath; and (3) E-Learning presentation of games and simulations to motivate younger trainees. The training is designed to familiarize participants with the iPad and the SRTS program. Participants will be told how to use the system and how often to use the system. SRTS program participants will each be assigned an iPad to take home with them and practice the techniques for a period of two months.

This is a 10-item scale designed to measure the degree to which a person perceives aspects of their life as uncontrollable, unpredictable and overwhelming. Participants are asked to indicate how often they have felt a certain way in the last month. The scale utilizes a 5-point likert format with responses ranging from never to very often.

The scale consists of seven different components of sleep quality that sum to an overall sleep quality score. A global score of 0-5 indicates good sleep quality while a global score greater than 5 indicates poor sleep quality. The global score as well as the sleep latency and habitual sleep efficiency scores will be used as continuous variables (Buysse, 1989).

The scale was initially developed to screen for generalized anxiety disorder, but has sensitivity and specificity to panic, social anxiety, and PTSD. The instructions ask respondents to indicate how often they have been bothered by problems over the past two weeks. Scores are obtained from likert responses that range from 0 "Not at all" to 4 "Nearly every day". The total score can range from 0 to 21, with scores of 5, 10, and 15 being cutpoints for mild, moderate, and severe anxiety, respectively. The measure will be utilized to gain anxiety symptom severity scores (Spitzer et al., 2006).

The PCL is a 17-item self-report measure of the 17 DSM-IV symptoms of PTSD. The PCL has a variety of purposes, including screening individuals for PTSD, diagnosing PTSD and monitoring symptom change during and after treatment. We will use the PCL-C (civilian) version for this study. The PCL-C (civilian) asks about symptoms in relation to "stressful experiences." The PCL-C is useful because it can be used with any population. The symptoms endorsed may not be specific to just one event, which can be helpful when assessing survivors who have symptoms due to multiple events. Typically, it is optimal to assess traumatic event exposure to ensure that a respondent has experienced at least one Criterion A event.

• For both the SRTS and PMR iPad-based programs, compliance data will be collected and stored on each iPad. Data will include the number of times the program was opened, the date for each session and for how long the program was open on each occasion. Data will be downloaded from iPads when iPads are turned in at the end of two months. • Participants will also be asked to complete a self-report form, indicating how often, on average, they used the program and practiced the techniques per week.
