This study examined the psychometric properties of the Self-Appraisal of Change Scale, a measure designed to capture domains that are subjectively relevant to caregivers, associated with overall well-being, and amenable to change upon engaging in an intervention. Data from 107 caregivers of veterans with dementia enrolled in a randomized controlled trial of a telephone-delivered caregiver psychoeducation and support group program (the Telehealth Education Program (TEP)) were analyzed. The TEP, which was delivered by master’s prepared social workers and a nurse dementia care manager, targeted caregivers’ dementia-related knowledge, attitudes, and self-management skills. Analyses were conducted to determine the factor structure, reliability, validity, and measurement invariance of the scale. Factor analyses yielded a single-factor solution for the scale’s nine items. The reliability and construct validity of the scale were also supported by the analyses. Multi-group analyses suggested that meaningful comparisons of scale items and total raw scores can be made across usual care (UC) and intervention groups. The findings offer preliminary support that the scale may represent a valid and reliable instrument that captures perceived changes in key domains (e.g. caregiving knowledge, attitudes, and skill) following participation in a psychoeducational and support intervention trial. 相似文献

Experimental research suggests the differentiation of ‘nice’ and ‘nasty’ theory of mind (ToM). Over 5000 parents from the Twins Early Development Study reported on nice (e.g., being considerate) and nasty (e.g., blaming others) behaviours following their twins’ second, third, and fourth birthdays. Factor analyses yielded four factors and it was proposed that these related to prosocial behaviour necessitating ToM (Nice ToM), antisocial behaviour necessitating ToM (Nasty ToM), and prosocial and antisocial behaviour not necessitating ToM (Nice and Nasty). Interscale correlations, gender differences, and their relationship with language were consistent with this distinction. Both ToM scales showed moderate heritability and significant environmental influences (shared and nonshared). Bivariate analyses indicated somewhat distinct aetiological influences on Nice ToM versus Nasty ToM. However, further research is needed to confirm whether this distinction reflects interactions between ToM and temperament, or two underlying genetic and cognitively distinct ToM abilities. 相似文献

Children are becoming an increasingly important focus for exposure and risk assessments because they are more sensitive than adults to environmental contaminants. A necessary step in measuring the extent of children's exposure and in calculating risk assessments is to document how and where children spend their time. This 1990-1991 survey of 1000 households was designed for this purpose, targeting children between 5 and 12 years of age, in six states in varied geographic regions. The behavior of children was sampled on both weekdays and weekends over all four seasons of the year using a retrospective time diary to allocate time to activities during the previous 24 h. Information was obtained on the kinds and locations of activities, the nature of the microenvironments of the locations, and the time spent in the different environments. Measures of variability in addition to mean hours per day are reported. Results of this study closely match those of earlier research on California children's activities done by the California Air Resources Board. One important finding of the survey was that 5- to 12-year-old children in all geographic regions spend most of their time indoors at home, indicating that risk assessments should focus on indoor, on-site hazards. 相似文献

This paper presents evidence concerning the effect of unionization on the average productivity of labor using time-series
data from the private, domestic sector of the U.S. economy over the 1948–73 period. Aggregate technology is specified by a
constant-returns-to-scale, Cobb-Douglas production function which incorporates union and nonunion labor and proxies for both
embodied and disembodied technical change. Maximum likelihood estimates of the model indicate that union membership significantly
decreased average labor productivity, holding constant the quality and mix of capital and labor and controlling for cyclical
effects.

Abstract Virtually all past studies of the effect of community context on families and children have focused on large metropolitan communities. Using a sample of divorced women living in small, Midwestern communities, the present study tests a model of the processes whereby community structure influences parenting practices. Results obtained through structural equation modeling supported the hypotheses. High concentrations of disadvantaged people within a community were indirectly related to parenting through community social disorganization. Community social disorganization had a direct effect on quality of parenting, as well as indirect effects through negative events, access to social support, and depressed mood. The various methodological and theoretical implications of these findings are considered. 相似文献
