Identifying coronary-prone behavior in adolescents using the Bortner Self-Rating Scale

Brief measures to identify coronary-prone (Type-A) behavior in young persons are greatly needed for longitudinal epidemiologic study of cardiovascular diseases. We examined the suitability of a modified 14-item Bortner Self-rating Scale (ABS) for use in an adolescent population. Responses of 549 racially mixed, low to middle income urban high school students were analyzed to see if ABS measurement properties matched those of the parent version. Construct validity was explored by correlating ABS scores with measures of anger expression, social support, life satisfaction, academic achievement and blood pressure. Results disclosed that the distribution and factor structure of adolescent ABS responses closely resembled findings obtained with adults. Scale validity was supported by significant associations of ABS scores with degree of overt anger expression, lack of social support, and dissatisfaction with school and life in and life in general. Academic achievement and blood pressure were found not to correlate with adolescent ABS scores. Possible race and sex differences are considered.
