Behavioral precursors to accidents and resulting physical impairment.

The main goal of the study was to determine, within a model of emotional and behavioral regulation, if there are developmental precursors to accidents and resulting physical impairment. Data collected at ages 8 and 14 with 147 males and 142 females using peer nomination and teacher rating were related to the number of types of accidents the subjects had been in and impairment as a result of an accident by the age of 27 when the subjects were interviewed on their health. The results showed that 44% of the men and 14% of the women had been in an accident. Severe effects on health were obtained for 19% of the men and 5% of the women. Accidents and impairment were most frequent among individuals whose behavior had been characterized by low emotional and behavioral control. The most generalized predictor of accidents and impairment was noncompliance in childhood. In adulthood, heavy drinking increased the risk of accidents. Aggression and conduct problems were the most significant precursors to male impairment, although several subgroups of men who were impaired were found. For females, the predictions of accidents and impairment were less accurate than for males.
