This study tested structural relationships within a model proposed to explain the manner in which self-esteem changes are associated with exercise experiences. As initially assessed by self-efficacies (EFFs) specific to physical tasks within a training program, we postulated that competence can generalize to feelings of global self-esteem (SE) through an intervening construct of perceived physical competence (PC). Three measures of EFF and two each of PC and SE were administered to 145 people in their mid- to late adulthood. Confirmatory factor analysis examined orthogonal and oblique versions of three measurement models and identified three distinct but correlated factors, each assessed by its hypothesized indicators. Alternative structural equation models were specified and tested using both normal and nonnormal estimation procedures. The proposed model provided the most parsimonious fit and explained 29% of the variance in SE. Confirmation of its structural relationships provides preliminary validity for model use in examining the manner in which exercise experiences influence levels of self-perception. 相似文献

Psychometric characteristics of the Adult Suicidal Ideation Questionnaire in college students 总被引:1,自引:0,他引:1
W M Reynolds 《Journal of personality assessment》1991,56(2):289-307
There is a growing concern for identifying individuals at risk for suicidal behaviors. Suicidal ideation, that is, the thoughts and cognitions one has about suicidal behaviors and intent, may be considered a primary marker for the risk of more serious suicidal behaviors. This investigation examined the reliability and validity of the Adult Suicidal Ideation Questionnaire (ASIQ; Reynolds, in press-a), a 25-item self-report suicidal ideation measure designed for adults. Subjects were 474 college students from two Midwestern universities. Results indicated high internal consistency (r alpha = .97) and test-retest (rtt = .86) reliability of the ASIQ with college students. Significant correlations (rs = .38 to .60) were found with measures of depression, hopelessness, anxiety, and self-esteem. For the total sample, a multiple correlation of .67 was found between the ASIQ, the independent variables just noted, and history of prior suicide attempt. Factor analysis of the ASIQ produced a four-factor solution. Psychometric support for the utilization of the ASIQ in clinical and research settings is presented and discussed. 相似文献

The factorial validity and internal consistency reliability of the Devereux Elementary School Behavior Rating Scale was examined using a random sample of elementary-school children in grades I through 6. Teacher ratings of subjects' classroom behaviors on the Devereux approximated ratings obtained by the standardization sample. Internal consistency (coefficient alpha) reliability coefficients of the 11 Devereux subscales were found to be quite adequate, ranging from 80 to 93. Intercorrelations among Devereux subscales were moderate to high. A principal factor analysis of the 11 subscales produced two factors with eigenvalues greater than 1.0, which cumulatively accounted for 70.2% of the total variance. When rotated via an orthogonal (Varimax) solution, the two resultant factors appeared to measure emotional adjustment and academic related dimensions of classroom behavior. Given the problem of multicollinearity that was shown to exist among subscales, the authors suggest caution in the interpretation of Devereux subscales as discrete factors.The authors gratefully acknowledge computer support funding provided by the University of Wisconsin, Graduate School Research Committee Grant 135-1537 to the first author. 相似文献

In contrast to the findings of Bransford and Franks (1971) that no specific information is retained about acquisition sentences in their recognition memory paradigm, it was shown that subjects can consistently distinguish OLDs from NEWs when visual presentation is used, but not when auditory presentation is used. This is in agreement with the speculation of Katz and Gruenewald (1974) as to why such a split was observed in their study. This difference also has a bearing on the typical finding of no modality effects in long-term memory, as compared to the consistent superiority of auditory presentation in short-term memory. It was also found that blocking semantically related sentences during acquisition heightened the perceived "OLDness" of test sentences compared to nonblocked presentation. 相似文献

The present study undertakes a comprehensive and critical review of the body of empirical work on entrepreneurial passion. In particular, we document how the “first generation” of research on entrepreneurial passion and work passion in entrepreneurs has gained growing attention in various sub-fields of entrepreneurship research including entrepreneurial management, psychology, and finance. We provide an overview over theories used, definitions and measurements adopted, research methods utilized (e.g., qualitative vs. quantitative, survey-based vs. experimental/intervention), the thematic focus of studies, and unit of investigation (e.g., individual vs. team). We not only flag the problems of inconsistencies and limitations with respect to theory use, the making of causal inferences, and the conceptualization and measurement of entrepreneurial passion in existing studies (e.g., jingle fallacies), but also review the antecedents and outcomes of entrepreneurial passion identified in prior work and work where it had been examined as a moderator. Following this, we offer a research agenda with concrete suggestions to act as a foundation for the “second generation” of entrepreneurial passion research that proactively addresses the issues and gaps identified in our review. Finally, we also highlight how insights from the entrepreneurial passion literature can inform scholarship on passion more broadly. 相似文献

Clinicians working in the field of acquired brain injury (ABI, an injury to the brain sustained after birth) are challenged to develop suitable care pathways for an individual client’s needs. Being able to predict psychosocial outcomes after ABI would enable clinicians and service providers to make advance decisions and better tailor care plans. Machine learning (ML, a predictive method from the field of artificial intelligence) is increasingly used for predicting ABI outcomes. This review aimed to examine the efficacy of using ML to make psychosocial predictions in ABI, evaluate the methodological quality of studies, and understand researchers’ rationale for their choice of ML algorithms. Nine studies were reviewed from five databases, predicting a range of psychosocial outcomes from stroke, traumatic brain injury, and concussion. Eleven types of ML were employed with a total of 75 ML models. Every model was evaluated as having high risk of bias, unable to provide adequate evidence for predictive performance due to poor methodological quality. Overall, there was limited rationale for the choice of ML algorithms and poor evaluation of the methodological limitations by study authors. Considerations for overcoming methodological shortcomings are discussed, along with suggestions for assessing the suitability of data and suitability of ML algorithms for different ABI research questions. 相似文献

Differential functioning of the Beck depression inventory in late-life patients: use of item response theory 总被引:1,自引:0,他引:1
The present analyses examined age-related measurement bias in responses to items on the revised Beck Depression Inventory (BDI) in depressed late-life patients versus midlife patients. Item response theory (IRT) models were used to equate the scale and to differentiate true-group differences from bias in measurement in the 2 samples. Baseline BDI data (218 late life and 613 midlife) were used for the present analysis. IRT results indicated that late-life patients tended to report fewer cognitive symptoms, especially at low to average levels of depression. Conversely, they tended to report more somatic symptoms, especially at higher levels of depression. Adjusted cutoff scores in the late-life group are provided, and possible reasons for age-related differences in the performance of the BDI are discussed. 相似文献

Neuropsychologists are asked frequently to address the issue of the cause of a variety of central nervous system problems that may affect higher cortical function. One such issue is the relationship of maternal smoking to adverse reproductive outcomes involving neocortical insult including mental retardation, learning disabilities, attention-deficit hyperactivity disorder, and other insults that may be related to prolonged hypoxic states in utero. The instant paper develops the issue of causation as a scientific inquiry, reviews several traditional, applicable models, and critiques these models. An additional model of motility is proposed and discussed. The issue of the relationship of maternal smoking to adverse reproductive outcomes is then addressed from a review perspective along with new empirical analyses, the latter demonstrating that researchers tend to draw causal conclusions independent of whether the respective design of their studies would support conclusions about the causation of an event. Causal conclusions in the absence of causal designs have often lead to incomplete and incorrect conclusions. It is necessary to match conclusions not only to the outcomes of a research project but also to its design and accompanying limitations. 相似文献
