The reliability and validity of a revised version of Finucci's (1982) Reading History Questionnaire was examined in two adult samples. One sample included 84 adults from an ongoing study of familial dyslexia, and a second sample was composed of parents of 107 children from a longitudinal study of reading development. Internal consistency was demonstrated by Cronbach's alphas of .94 and .92 in the two samples. Test-retest reliability was demonstrated by significant correlations (.87 and .84 in the two samples) over several years between an earlier and revised form of the questionnaire. Validity was demonstrated via (a) correlations between the questionnaire score and reading measures (rs = .57-.70), (b) the results of a discriminant function analysis that used questionnaire scores to predict reading disability diagnosis, and (c) the finding that the questionnaire had substantial incremental validity in predicting reading skill in a hierarchical regression analysis that first entered IQ and SES. These results indicated that the questionnaire is both reliable and valid. 相似文献

OBJECTIVE: The goal was to develop a retrospective inventory of parental threatening behavior to facilitate a better understanding of such behavior's role in the etiology of psychological distress. METHOD: Inventory items were developed based on theory and 135 students' responses to a question eliciting examples of threatening parental behavior. Following item development, two additional student samples (n = 200 and n = 603) completed batteries of self-report measures. Responses were used to eliminate unstable or redundant items from the inventory and to examine the inventory's psychometric properties. RESULTS: Factor analysis of the inventory revealed three factors, accounting for 66.2% of variance; this factor structure is compatible with theory, and consistent across maternal behavior scores, paternal behavior scores, and combined maternal and paternal scores. Cronbach's coefficient alphas indicated acceptable internal consistency; Pearson correlation coefficients indicated acceptable 4-week test-retest reliability. Moderate intercorrelations with two retrospective measures of childhood experiences suggested construct validity. Regression analyses demonstrated the ability of the inventory to predict both anxious and depressive symptomatology and lifetime symptoms of anxiety and depressive disorder. Normative data on combined parent scores, maternal scores, and paternal scores are also presented. CONCLUSIONS: Initial psychometric testing of the Parent Threat Inventory (PTI) suggests it is a reliable and valid tool for investigating the developmental antecedents of adult psychological distress. Further research should focus on addressing two limitations: (1) lack of normative and psychometric data on men and women suffering from clinical disorders, and (2) lack of validation by parental reporting. 相似文献

OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided. 相似文献

ABSTRACTThe widespread assumption in the United States today is that traditional urban public schools are failing. Market-based solutions, particularly charter schools, are seen as the way to improve urban education. How then can we understand a large urban district where educational actors have furthered a locally popular alternative vision? This article analyzes the comparison of Indianapolis, IN and Louisville, KY to demonstrate how four-decades-old desegregation orders continue to matter for the perceptions of urban school districts. The analysis shows how actors in Louisville utilized more favorable perceptions to fight for a compelling alternative narrative–integration–and against charter schools. 相似文献
