The effect of surface and season on playground injury rates.

Adolescent chronic pain: the ability to cope.

The study investigated differences in mother-child interaction, child personality, and family characteristics between adolescents who were coping with chronic benign intractable pain and adolescents who were not. Both groups experienced a similar amount and intensity of pain. Behavioural observations indicated that non-copers engaged in significantly more negative behaviour than the copers.
