IQ scores among homeless older adolescents: characteristics of intellectual performance and associations with psychosocial functioning.

Intellectual performance and the associations of IQ with the quality of psychosocial functioning were studied in a sample of homeless older adolescents. Fifty homeless older adolescents (ages 16-21) completed the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and a questionnaire assessing psychosocial functioning and sexual risk factors. The WAIS-R scores were comparable to population means, with performance IQ scores tending to be higher than verbal IQ scores. The IQ was unrelated to the duration of homelessness. Higher IQ scores were significantly correlated with only a minority of the measures of psychosocial functioning, including less self-reported depression and lower reported delinquency, but also less self-control in high-risk sexual situations, less perceived peer support for safer sex, and a higher perceived likelihood of acquiring HIV.
