The present study describes the reliability and the validity evidence concerning a measure of a generalized perceived control for children (GPCC). A four points scale questionnaire consisting of 40 items was administrated to 353 Japanese primary and junior high school children. Construction procedures leading to the final 26-item scale were described. Score on the GFCC scale showed high internal consistency (α=.78) and a high test-retest reliability (r=.88). The validity of the GPCC scale was conformed to the following results: 1) Correlation between the GPCC scale and the CNS-IE (Nowicki, & Strickland, 1973) was -0.48 (p<0.001). 2) Compared to children with high-perceived control, children with low one showed more maladjustment symptoms, such as a stronger disire and inclination to not attending school, all proving a feeling of interpersonal maladjustment. 3) In the case of a controlled IQSS, the significant relationship between the GPCC and academic achievement with primary school children was partially proved.
