“…There is moderate intraindividual stability in the CAR and the decline across the day. The patterns of change in the CAR and in the daily decline have been associated with many psychosocial variables in adolescents, including psychopathology, social relationships, academic performance, health status including weight status, and social contexts (e.g., Adam et al., ; Alink et al., ; Drake, Sladek, & Doane, ; Huynh, Guan, Almeida, McCreath, & Fuligni, ).
