Commentary - "Factor analyses of the family assessment device," by Ridenour, Daley, & Reich

Ridenour, Daley, and Reich conducted a series of factor analyses using the correlational matrix of the subscale scores of the Family Assessment Device (FAD), published in Family Process, December, 1999. They conclude that "th e FAD subscales be reorganized from their current seven-subscale format" (p . 507). We propose that this suggestion for reorganization is premature and based on the inappropriate application of an "internal consistency" model of scale construction to the FAD. We further suggest that the most importan t criteria regarding an assessment instrument are those of reliability, val idity, and clinical utility. In the absence of this Kind of data regarding alternative organizations of the FAD, rue believe that the original subscal es remain the best choice.
