This study reports correlations between the High School Personality Questionnaire and various indices of school achievement and compares the validities with prior studies. Three achievement scores are utilized: a self-report of high-school grades, a parental report of high-school grades several years after the testing, and actual college grades several years after the testing. In all cases, the results were similar and substantial, and consonant with typical values from earlier, nonlongitudinal studies. 相似文献

This study assessed the differential contribution of personality to the explanation of variance in achievement in the mother tongue and mathematics at the high school level. The results indicated that personality, as measured by the HSPQ, aided the explication of variance in achievement in the mother tongue significantly, but had little influence on mathematics. Personality contributed as much to the explanation of variance in the mother tongue as did the composite cognitive variable. The influence of personality on achievement in mathematics was shown to be negligible. Some practical implications for the teaching of the first language are drawn. 相似文献

The purpose of the present study was to do a canonical correlation analysis of demographic information and the Behavior Problem Checklist (BPCL) in order (a) to employ the demographic information in a manner that had not been possible using other methods, and (b) to examine the four factors on the BPCL as a general measure of mental health and mental illness. Subjects were 2,314 children who differed in grade in school, sex, social class, ethnic group status, and type of class in school (i.e., regular or special education). Teachers provided the demographic information and the BPCL ratings. It was found that the four factors on the BPCL were significantly correlated. It was also found that there were four canonical correlations between the demographic information and the BPCL ratings of which three were and one was not significant. The meanings of the four canonical correlations were described for the demographic information and for the four factors on the BPCL. 相似文献

Data were collected from a sample of school psychologists and teachers after termination of a teacher consultation experience. Stepwise regressions were performed on the data to determine which psychologist and teacher variables were related to teacher satisfaction with the school psychological consultation. The single most significant main effect on teacher satisfaction was the teacher's perception of the psychologist's facilitativeness. 相似文献
