The present study examined whether ineffective discipline, single parent status, social support, parent involvement, and parent depression predicted changes in preschoolers' (N = 129) behavior problems. This study also evaluated whether child sex and ethnicity moderated the relations between these variables and changes in problem behavior. Parents completed questionnaires at the beginning of the study, and parent, teacher, and observational ratings of children's behavior problems were collected twice during the school year. Parents' own social support predicted improvement for boys and parent depression was associated with worsening symptoms for girls. Single parenthood and parent involvement predicted changes in behavior problems for the sample as a whole. Several significant ethnic differences emerged, highlighting the importance of considering cultural context in studies of parenting and child externalizing behavior.  相似文献

ABSTRACT

Angular direction is a source of information about the distance to floor-level objects that can be extracted from brief glimpses (near one's threshold for detection). Age and set size are two factors known to impact the viewing time needed to directionally localize an object, and these were posited to similarly govern the extraction of distance. The question here was whether viewing durations sufficient to support object detection (controlled for age and set size) would also be sufficient to support well-constrained judgments of distance. Regardless of viewing duration, distance judgments were more accurate (less biased towards underestimation) when multiple potential targets were presented, suggesting that the relative angular declinations between the objects are an additional source of useful information. Distance judgments were more precise with additional viewing time, but the benefit did not depend on set size and accuracy did not improve with longer viewing durations. The overall pattern suggests that distance can be efficiently derived from direction for floor-level objects. Controlling for age-related differences in the viewing time needed to support detection was sufficient to support distal localization but only when brief and longer glimpse trials were interspersed. Information extracted from longer glimpse trials presumably supported performance on subsequent trials when viewing time was more limited. This outcome suggests a particularly important role for prior visual experience in distance judgments for older observers.  相似文献

ABSTRACT

Everyday multitasking and its cognitive correlates were investigated in an older adult population using a naturalistic task, the Day Out Task. Fifty older adults and 50 younger adults prioritized, organized, initiated, and completed a number of subtasks in a campus apartment to prepare for a day out (e.g., gather ingredients for a recipe, collect change for a bus ride). Participants also completed tests assessing cognitive constructs important in multitasking. Compared to younger adults, the older adults took longer to complete the everyday tasks and more poorly sequenced the subtasks. Although they initiated, completed, and interweaved a similar number of subtasks, the older adults demonstrated poorer task quality and accuracy, completing more subtasks inefficiently. For the older adults, reduced prospective memory abilities were predictive of poorer task sequencing, while executive processes and prospective memory were predictive of inefficiently completed subtasks. The findings suggest that executive dysfunction and prospective memory difficulties may contribute to the age-related decline of everyday multitasking abilities in healthy older adults.  相似文献

In view of reported effects of strenuous and exhaustive exercise on CNS activity, it was hypothesized that “fatiguing” exercise may influence learning retroactively as predicted by consolidation theory. Prelimary findings from two animal experiments are reported followed by a discussion of implications for future research.  相似文献

Late‐life depression (LLD) has detrimental effects on family caregivers that may be compounded when caregivers believe that depressive behaviors are volitional or within the patient's capacity to control. In this study we examined three person‐centered caregiver attributions that place responsibility for LLD on the patient (i.e., character, controllability, and intention), and the impact of such attributions on levels of general caregiver burden and burden specific to patient depressive symptoms. Participants were 212 spouses and adult children of older adults enrolled in a depression treatment study. Over one third of caregivers endorsed character attributions, which significantly predicted greater levels of both general and depression‐specific burden. Intention attributions were significantly associated with general burden, but not depression‐specific burden. Contrary to our expectation, controllability attributions did not predict either type of burden. Our findings suggest that the assessment of family caregiver attributions for LLD may be useful in identifying caregivers at risk for burden and subsequent health effects, as well as those who may need education and support to provide effective care to a vulnerable population of older adults.  相似文献

Community-Based Participatory Research is a research paradigm that encourages community participation in designing and implementing evaluation research, though the actual outcome measures usually reflect the “external” academic researchers’ view of program effect and the policy-makers’ needs for decision-making. This paper describes a replicable process by which existing standardized psychometric scales commonly used in youth-related intervention programs were modified to measure indicators of program success defined by community partners. This study utilizes a secondary analysis of data gathered in the context of a community-based youth violence prevention program. Data were retooled into new measures developed using items from the Alabama Parenting Questionnaire, the Hare Area Specific Self-Esteem Scale, and the Youth Asset Survey. These measures evaluated two community-defined outcome indicators, “More Parental Involvement” and “Showing Kids Love.” Results showed that existing scale items can be re-organized to create measures of community-defined outcomes that are psychometrically reliable and valid. Results also show that the community definitions of parent or parenting caregivers exemplified by the two indicators are similar to how these constructs have been defined in previous research, but they are not synonymous. There are nuanced differences that are important and worthy of better understanding, in part through better measurement.  相似文献

Background: Reflective practice in health care social work ensures that social workers provide effective and efficient services to clients as well as maintaining their mental and physical health. In this study, we aim to determine how health care social workers engage in and describe reflective practice and challenges related to their reflective practice in their work in the health care system.

Methods: We used the Reflective Dialogue Rating Scale (RDRS) developed by Marion Bogo et al. to structure qualitative face-to-face interviews with 23 health care social workers employed in a hospital in a large urban area in Ontario, Canada.

Results: Findings illustrated that all participants regularly engaged in reflective practice in order to carry out everyday social work activities, promote ethical practice, and to enhance the provision of services to their clients. The social worker participants consistently agreed that as a profession they faced challenges maintaining their knowledge of current research due to few opportunities for professional development, workload competing with educational opportunities, and a work climate that is not conducive to gaining professional development, thereby challenging reflective practice. Supportive working environments include: peer supervision, safe and private spaces to talk to colleagues, a supportive supervisor, and an overall positive organizational culture.

Discussion and conclusion: Reflective practice is a key component in health care social work. All 23 social workers stated that they used reflective techniques (such as peer supervision and debriefing) to deal with their own reactions and operated in a purposeful and intentional manner to form therapeutic relationships with clients. As such, participants stated that lifelong learning was paramount in providing quality care to clients.  相似文献

Research indicates self-esteem reflects many factors in a person’s life, such as relationships with parents or parent figures, attachment types, experiences of worth enhancement, ethnicity, generation, and cultural values. However, debate continues on whether self-esteem is simply a reflection of Western culture and may not be a universal factor of human nature. This research was undertaken to understand how four persons of diverse ethnic, gender, and age categories may each perceive the self from reading the same story. First, the authors offer a brief overview of how self-esteem is viewed and explore a few cultural, gender and age aspects of self-esteem. They then present our pilot study with the methodology, results, and discussion, and offer implications for mental health counselors.  相似文献
