A confirmatory item factor analysis of the Waring Intimacy Questionnaire (WIQ) was performed on samples of 198 married college students, 148 married psychiatric patients, and 218 married members of a random sample of residents in an urban community. For the nine hypothesized factors, 95%, 98%, and 97% of the items loaded appropriately in each of the three samples. Across samples 84% of the items loaded appropriately. Furthermore the pattern of loadings was predominantly univocal. The results suggest that the instrument has a structure consistent with its scoring key.
