Rates of rehospitalization of individuals with serious and persistent mental illness were compared prior to and after they were moved into 4-bed corporate foster homes. Results showed a significant drop in the number of rehospitalizations and in the total number of days hospitalized after moving into a 4-bed home. The data suggest that living in a 4-bed home-like environment may result in significantly fewer and shorter hospitalizations for these types of mentally ill individuals.  相似文献

This study investigated whether hopelessness and depression were risk factors for suicidal thoughts and behaviors in African American adolescents and looked at whether religious participation and religious coping protected these students from suicidality. Participants were 212 African American high school students (133 females, 79 males). The results of multiple and logistic regression analyses found that hopelessness and depression were risk factors for suicidal ideation and attempts. Religious coping style was significantly related to suicidal behaviors: Self-directed coping was related to increased hopelessness, depression, and suicide attempts, and collaborative coping was related to increased reasons for living. Gender differences were found in symptoms of depression, religious coping style and religious participation. Results provide additional support for suicide interventions to target hopelessness and depressive symptoms and highlight the importance of examining the role of culturally salient variables, such as religious participation and religious coping style, when developing intervention programs for suicide.  相似文献

The current set of studies compared the psychometric properties of the original Comprehensive Effects of Alcohol Questionnaire (CEOA) to a 15-item version (B-CEOA) in a nonclinical undergraduate sample (N = 581), and attempted to replicate and extend the B-CEOA findings in an undergraduate sample referred to an alcohol intervention (N = 734). Psychometric assessment included construct validity, internal consistency, and concurrent validity, using both positive and negative expectancy items in all analyses. Results provided further support for the empirical validity of the original CEOA, and provided support for the use of the B-CEOA despite the reduction in the number of items. The B-CEOA factor structures obtained using exploratory and confirmatory techniques provided support for a 4-factor structure of expectancies and 3-factor structure of valuations. Findings reveal potential problems with positive and negative expectancy items. Trade-offs regarding factor structure, internal consistency, and administration time should be considered in using the B-CEOA vs. the CEOA.  相似文献

A number of environmental agents have been shown to demonstrate neurotoxic effects either in human or laboratory animal studies. Critical windows of vulnerability to the effects of these agents occur both pre- and postnatally. The nervous system is relatively unique in that different parts are responsible for different functional domains, and these develop at different times (e.g., motor control, sensory, intelligence and attention). In addition, the many cell types in the brain have different windows of vulnerability with varying sensitivities to environmental agents. This review focuses on two environmental agents, lead and methylmercury, to illustrate the neurobehavioral and cognitive effects that can result from early life exposures. Special attention is paid to distinguishing between the effects detected following episodes of poisoning and those detected following lower dose exposures. Perinatal and childhood exposure to high doses of lead results in encephalopathy and convulsions. Lower-dose lead exposures have been associated with impairment in intellectual function and attention. At high levels of prenatal exposure, methylmercury produces mental retardation, cerebral palsy and visual and auditory deficits in children of exposed mothers. At lower levels of methylmercury exposure, the effects in children have been more subtle. Other environmental neurotoxicants that have been shown to produce developmental neurotoxicity include polychlorinated biphenyls (PCBs), dioxins, pesticides, ionizing radiation, environmental tobacco smoke, and maternal use of alcohol, tobacco, marijuana and cocaine. Exposure to environmental agents with neurotoxic effects can result in a spectrum of adverse outcomes from severe mental retardation and disability to more subtle changes in function depending on the timing and dose of the chemical agent.  相似文献

The present study examined the relationship between a self-presentational style involving an extreme need to conceal perceived imperfections from others and body image disturbance (BID). Findings from both a community and a university sample indicated that nondisplay of imperfection (i.e., concerns over behavioral displays of imperfections to others) predicted BID beyond self-imposed perfectionistic expectations and other contributors to BID. Mediational analyses suggested that dysfunctional appearance schemas represent one possible mechanism through which nondisplay of imperfection influences BID. In contrast to earlier work on perfectionism and BID, which emphasized the role of self-imposed perfectionistic expectations, the current study offers a novel view of the connection between perfectionism and BID. That is, rather than striving to achieve perfection, the present study suggests that individuals with BID are characterized by a strong need to avoid appearing imperfect to others.  相似文献

Episodic memory is the ability to remember personally experienced past events (Tulving in Organization of memory. Academic Press, San Diego, pp. 381–403, 1972). In non-human animals, the behavioural criterion for episodic-like memory is remembering “what” occurred in conjunction with “when” and “where” (Clayton and Dickinson in Nature 395:272–274, 1998). We conducted tests for “what, where, and when” memory in a food-storing bird, the black-capped chickadee (Poecile atricapillus). In Experiment 1, chickadees found sunflower seeds and mealworms in concealed sites in their home cage. Birds later re-visited these sites after either a short (3 h) or long (123 h) retention interval. Chickadees normally prefer mealworms, but at the long retention interval mealworms were degraded in taste and appearance. Chickadees showed some memory for what kind of food they had encountered and where, but no memory for when food had previously been found. Experiment 2 followed a similar procedure, except that chickadees searched for hidden sunflower seeds and mealworms in trees in an indoor aviary. These more natural conditions increased both the spatial scale of the task and the effort required to find food. In this experiment, birds showed evidence for all three components of what–where–when memory. Unlike some previous studies of episodic-like memory, birds’ behaviour cannot be accounted for by differential memory strength for more recent events. The results show that memory for what, where, and when occurs in food-storing birds outside the corvid family, does not require food caching or retrieval, and that remembering “when” can depend on the nature of the task.  相似文献

Development does not take place in isolation and is often interrelated with close others such as marital partners. To examine interrelations in spousal happiness across midlife and old age, we used 35-year longitudinal data from both members of 178 married couples in the Seattle Longitudinal Study. Latent growth curve models revealed sizeable spousal similarities not only in levels of happiness but also in how happiness changed over time. These spousal interrelations were considerably larger in size than those found among random pairs of women and men from the same sample. Results are in line with life-span theories emphasizing an interactive minds perspective by showing that adult happiness waxes and wanes in close association with the respective spouse. Our findings also complement previous individual-level work on age-related changes in well-being by pointing to the importance of using the couple as the unit of analysis.  相似文献

Perfectionism is a putative risk factor for depressive symptoms. However, most research in this area uses cross-sectional designs (which fail to address temporal precedence) and mono-source designs (which are influenced by various biases). The present study overcomes these limitations by using a novel design involving both self- and informant reports of self-critical perfectionism (i.e., negative reactions to perceived failures, concern over others’ criticism and expectations, doubts about performance abilities, and intense self-rebuke). It was hypothesized that self- and informant reports of self-critical perfectionism would correlate moderately and that self- and informant reports of self-critical perfectionism would predict increases in depressive symptoms over time. A sample of 155 target participants and 588 informants was recruited and studied using a prospective longitudinal design. All study hypotheses were supported, including evidence that self- and informant reports of self-critical perfectionism each add incrementally to the understanding of the self-critical perfectionism–depressive symptoms connection. Informant reports may provide a more complete picture of the self-critical perfectionist and her or his vulnerability to depressive symptoms.  相似文献
