Objective:
To test the reliability and validity of the behavior rating scale of executive function (BRIEF) parent form for school age children in China.
Methods:
A total of 216 patients [attention deficit hyperactivity disorder (ADHD) or schizophrenia or autism] and 311 normal controls were involved in this research. parents of the subjects completed the BRIEF, ADHD rating scale-IV, Conners, and Rutter rating scales. And performance-based tests of executive function were carried out among some of the controls and ADHD subjects. These tests included Rey-Osterrieth complex figure (ROCF),trail-making test, digit span test, Tower of Hanoi (TOH), and Stroop test.
Results:
Test-retest reliability was 0.68-0.89 and Cronbach a coefficient was 0.74- 0.96 except for the initial subscale (0.61). Subscales of BRIEF were moderately correlated (r=0.41-0.64) with subscales of other criteria scales such as ADHD rating scale-IV, etc. And there were correlations (r=0.32-0.41) between subscales of BRIEF and some indexes of the performance-based tests of executive function in the control group while the correlations in the diagnostic group were negative. For example, the inhibition subscale correlated with detailed score of ROCF delayed recall test and Stroop word-color interference time (r=-0.32, 0.38). The working memory subscale correlated with time for trial B of the trail-making test, numbers of backwards digit test and Stroop word-color interference time (r=0.30, -0.39, 0.41). Lisrel Confirmatory factor analysis showed that the 8-subscale model of BRIEF was reasonable. Compared with the control group, the diagnostic groups (ADHD-C, ADHD-I, schizophrenia and autism ) got significant higher scores almost on all subscales of BRIEF (Z=-3.17--4.17, P<0.01), respectively . And ADHD-C group got significant higher scores on inhibition, monitor and shift subscales of BRIEF than ADHD-I group (Z=-4.23--4.59, P<0.01).
Conclusion:
The BRIEF parent form for school age children was proved to have adequate reliability and validity in China.
