Examination of how psychological factors relate to illness severity among adolescents with inflammatory bowel disease (IBD) is rare. Further, studies have not accounted for the pervasive influence of negative affectivity (NA) or distinguished among subjective, behavioral, and objective measures of IBD severity. We examined how NA, positive affectivity, expressed hostility, and negative life events were related to subjective (pain, fatigue, disability), behavioral (health care contacts), and objective (erythrocyte sedimentation rate) illness severity among 56 adolescents with IBD. NA was positively related to subjective illness, and expressed hostility was inversely related to objective illness. Other relationships were eliminated after controlling for NA. Data suggest that NA and subjective illness are comanifestations of a single disposition, but that expressed hostility has an independent relationship with disease activity among adolescents with IBD.

Objective: This study examined the role of proximal maternal supervision in children's injury occurrence and severity among low-income families., Methods: We used a case crossover design and collected data about injury and control conditions for children aged 1-5 in 50 low-income families., Results: Higher levels of mothers' proximity to children predicted lower likelihood of injury occurrence. When controlling for child activity level, there was a trend for visual supervision to predict injury occurrence. The number of children in the home was also associated with lower supervision and higher prior injury frequency., Discussion: These findings provide evidence for the important role of maternal supervision in preventing unintentional injuries among low-income, at-risk children. Interventions that help at-risk caregivers provide closer supervision for their children are needed., (© The Author 2017.
