The role of biomedical and psychosocial processes in the intellectual and academic functioning of children and adolescents with cystic fibrosis.

This study found intellectual and academic functioning of 76 children and adolescents with cystic fibrosis to be normally distributed. Intellectual functioning was related inversely to age, and both intellectual and academic functioning were related directly to socioeconomic status. Medical status did not add a significant increment in the amount of variance in intellectual and academic functioning accounted for by age and socioeconomic status.
