Post-9/11 Veterans and Their Partners Improve Mental Health Outcomes with a Self-directed Mobile and Web-based Wellness Training Program: A Randomized Controlled Trial.
Veterans with history of deployment in the Global War on Terror face significant and ongoing challenges with high prevalences of adverse psychological, physical, spiritual, and family impacts. Together, these challenges contribute to an emerging public health crisis likely to extend well into the future. Innovative approaches are needed that reach veterans and their family members with strategies they can employ over time in their daily lives to promote improved adjustment and well-being. ⋯ Both veterans and partners were able to learn and make sustained use of a range of wellness practices taught in the MR program. Home-based, self-directed interventions may be of particular service to veterans who are distant from, averse to, or prohibited by schedule from using professional services. Leveraging the partner relationship may enhance sustained use of self-directed interventions for this population. Use of the MR program appears to be an accessible, low-cost approach that supports well-being and reduces multiple symptoms among post-9/11 veterans and their partners.

Randomized Controlled TrialEstimating Physical Activity and Sedentary Behavior in a Free-Living Context: A Pragmatic Comparison of Consumer-Based Activity Trackers and ActiGraph Accelerometry.
Activity trackers are increasingly popular with both consumers and researchers for monitoring activity and for promoting positive behavior change. However, there is a lack of research investigating the performance of these devices in free-living contexts, for which findings are likely to vary from studies conducted in well-controlled laboratory settings. ⋯ There was moderate-strong agreement between the ActiGraph and both Fitbit One and Jawbone UP for the estimation of daily steps. However, due to modest accuracy and systematic bias, they are better suited for consumer-based self-monitoring (eg, for the public consumer or in behavior change interventions) rather than to evaluate research outcomes. The outcomes that relate to health-enhancing MVPA (eg, "very active minutes" for Fitbit One or "active time" for Jawbone UP) and sedentary behavior ("idle time" for Jawbone UP) should be used with caution by consumers and researchers alike.
