A psychometric comparison of the positive and negative affect schedule across age and sex.

ABSTRACT

This study examined factorial and other psychometric characteristics of the Positive and Negative Affect Schedule in relation to mixed-sex youth (n 234) and adult (n 436) samples. Broadly, the results for both age groups were supportive of commonly reported statistical properties of the schedule. Although two factors were plainly identified, they were not clearly endorsed for either age group by confirmatory indices of fit. Within the adolescent sample, sex differences in response to the scales were noted.
