The purpose of this study was to use ecological momentary assessment to investigate the patterning of physical activity and sedentary behaviours in UK adolescents and to examine if different lifestyle groups differ on key explanatory variables. A total of 1,371 (38% boys, mean age 14.7 years) adolescents completed diaries every 15 min for 3 weekdays outside of school hours and 1 weekend day. Cluster analysis yielded five-cluster solutions for both boys and girls to explain the grouping of sedentary behaviours and physical activity. ⋯ Few demographic and environmental variables distinguished between clusters. The findings suggest a potential need for different behavioural targets in interventions to reduce sedentary behaviour in sub groups of the adolescent population. Further research is required to examine the modifiable determinants of different sedentary lifestyles among young people.

This original empirical study examined effects of a psycho-educational intervention on cancer patients' knowledge, concern, and preferences for cardiopulmonary resuscitation (CPR). We examined message framing as one factor that might impact subsequent decision making. In addition, we examined personality and coping style as predictors and moderators of patients' reactions to an informational intervention. ⋯ Message framing of survival data did not uniquely affect CPR preference. Higher optimism predicted less increase in concern about CPR, and higher hope predicted greater decrease in preference for CPR. More approach coping related to increased concern about CPR and decreased preference for CPR.
