Testing Interventions for Mobility through Exercise (TIME): Study protocol for a randomized trial comparing a novel, brief home-based exercise program and a standard home-based group exercise for older adults with mobility disability.

One in four older adults report difficulty walking, greatly increasing the risk of future disability and death. Though exercise improves mobility, too few older adults do it. While studies show that brief exercise sessions provide most of the benefit of longer sessions and that older adults note that "time" is a critical barrier to being active, what remains unknown is whether briefer RT sessions can improve mobility as well as, or better than, longer traditional sessions, possibly due to greater adherence.

Comparing preferences to evaluations of barrier self-efficacy for two strength training programs in US older adults.

Background/objectives: Engagement in regular physical activity is one of the best strategies for older adults to remain healthy. Unfortunately, only 35% of older adults meet guidelines for muscle strengthening activities. Eliciting participant preferences is one possible way to improve physical activity engagement.

Can't stop won't stop: problematic phone use, sleep quality, and mental health in U.S. Graduate students.

Objective: Prior work has suggested the impact of problematic phone use on the mental health of graduate students. This research explores the mediating effect of sleep quality on this link.

Participants: A total of 186 graduate students from the United States were collected using an online data acquisition platform.
