Children's mobile device (e.g., smartphone, tablet) access and ownership has grown substantially in the past decade. Concerns exist regarding excessive use and the impact of frequent consumption of mobile media on children's health and well‐being. We review the literature on the harmful physical health correlates of excessive mobile device use during childhood and adolescence. Strongest evidence emerged regarding the impact of excessive mobile device use and sleep outcomes. Mixed evidence emerged regarding excessive use of mobile devices and physical activity and obesity. Too few studies were identified to draw conclusions about mobile device use and the following health concerns in children: musculoskeletal outcomes/pain, ocular health, and migraine/headaches. Recommendations for future research on the association between excessive mobile device use and children's physical health outcomes (particularly investigations into the experience of musculoskeletal pain/discomfort, ocular symptoms, and neurological symptoms) are discussed.

Professionals who counsel and serve survivors of childhood abuse may be at risk of experiencing symptoms of post-traumatic stress disorder (PTSD), which can be exacerbated by cognitive and emotional processes. It is hypothesized that (1) a significant proportion of professionals who primarily serve child abuse survivors experience elevated levels of PTSD symptoms and (2) elevated PTSD symptoms are associated with psychological inflexibility processes, specifically increased experiential avoidance, cognitive fusion, and emotion regulation difficulties. Child abuse counselors and service workers ( N = 31) in a major metropolitan area were recruited for a small pilot study. Participants completed self-report measures of PTSD symptoms and levels of psychological flexibility processes. A significant proportion of counselors endorsed clinically significant PTSD symptoms ( n = 13, 41.9%). PTSD symptoms were significantly associated with experiential avoidance ( r = .54, p < .01) and emotion regulation difficulties ( r = .51, p < .01). These associations remained significant after controlling for the personality trait of emotional stability/neuroticism. These findings suggest that PTSD symptoms may be common among child abuse counselors and service workers, and these symptoms tend to be of greater intensity when responded to in avoidant and inflexible ways.
