Abstract

OBJECTIVE:

The objectives of this study were to determine whether a measure of global self-concept demonstrated longitudinal measurement invariance between adolescents aged 10-19 years with and without chronic illness and to document differences in their global self-concept trajectories over time.

METHODS:

Data were obtained from the National Longitudinal Survey of Children and Youth (N = 10,064). Global self-concept was measured using a scale based on the Self-Determination Questionnaire.

RESULTS:

16 percent of adolescents had chronic illness. There was evidence of partial longitudinal invariance in global self-concept between adolescents with and without chronic illness. Controlling for sociodemographic characteristics, adolescents with a chronic illness exhibited lower levels of global self-concept and more precipitous declines over time.

CONCLUSIONS:

The results from this study suggest that comparisons of global self-concept between adolescents with and without chronic illness are meaningful and, compared to healthy controls, adolescents with chronic illness are at risk for low global self-concept.
