Abstract :
The study used multiple-group confirmatory factor
analysis (CFA) and multiple indicators multiple causes
(MIMIC) procedures to examine the measurement and
construct equivalencies for father and mother ratings of
ADHD symptoms, recoded as binary scores. Fathers (N=
387) and mothers (N=411) rated their primary school-aged
children on the Disruptive Behavior Rating Scale (Barkley &
Murphy, 1998). For the multiple-group CFA analyses, the
results involving differences in practical fit indices supported
full measurement and construct equivalencies, whereas the chisquare
difference test showed lack of equivalency in five
symptoms for factor loadings, four symptoms for error
variance, and the variance and mean scores for the
hyperactivity-impulsivity factor. For the MIMIC analyses, six
symptoms lacked equivalency for thresholds. These findings
extend existing data in this area. The theoretical, psychometric
and clinical implications of the findings are discussed.
