Randomized Controlled Trial
Adaptive Goals and Reinforcement Timing to Increase Physical Activity in Adults: A Factorial Randomized Trial.
Potent lifestyle interventions to increase moderate-to-vigorous physical activity are urgently needed for population-level chronic disease prevention. This trial tested the independent and joint effects of a mobile health system automating adaptive goal setting and immediate financial reinforcement for increasing daily walking among insufficiently active adults. ⋯ This study offers automated and scalable-behavior change strategies for increasing walking among adults most at-risk for chronic diseases attributed to sedentary lifestyles.

In 2013, the U.S. Preventive Services Task Force again recommended alcohol misuse screening and provision of brief behavioral counseling interventions to those engaged in risky drinking for all adults aged ≥18 years in primary care. This report presents national estimates of the provision of alcohol screening and brief intervention by U.S. primary care physicians, the screening methods, and the resources they identified as helpful in implementing alcohol/substance screening and intervention in primary care settings. ⋯ Less than 40% of primary care physicians who screened patients for alcohol misuse reported always intervening with patients who screened positive for risky alcohol use. Collection of data on resources that primary care physicians report as being helpful for alcohol/substance screening and intervention implementation may be useful in continuous improvement efforts.
