This study examined the reliability and validity of a 12-min. walking test for coronary heart disease patients. CHD patients (28 men, 18 women) were recruited out of 86 CHD patients of the Martini Hospital Groningen, The Netherlands. 46 CHD patients (age M=66.0 yr., SD=6.8) participated in the reliability study and 24 (age M=62.0 yr., SD=9.2) in the validity study. A test-retest analysis showed a satisfactory Bland-Altman plot and an intraclass coefficient of .98. The Pearson correlation between the score on the test and the VO2 peak was .77. This test gives a reliable and valid assessment of cardiorespiratory fitness of CHD patients. 相似文献

This study examined the treatment sensitivity of the ADHD Questionnaire (ADHD-Q), which is a brief rating scale for measuring symptoms of inattention, hyperactivity, and impulsivity in children. Parent, teacher, and child self-report data of the ADHD-Q were obtained for 17 clinically referred children with ADHD on the three occasions: (1) during the regular intake assessment, (2) just before the start of the stimulant medication (i.e., methylphenidate) intervention, and (3) four weeks after the start of the medication intervention. Results showed that ADHD-Q scores remained fairly stable in the period prior to the intervention, but then showed a substantial decline after the stimulant medication had been administered. Clearly, this finding supports the treatment sensitivity of the ADHD-Q. 相似文献

Background. Worked examples are very effective for novice learners. They typically present a written‐out ideal (didactical) solution for learners to study. Aims. This study used worked examples of patient history taking in physiotherapy that presented a non‐didactical solution (i.e., based on actual performance). The effects of model expertise (i.e., worked example based on advanced, third‐year student model or expert physiotherapist model) in relation to students' expertise (i.e., first‐ or second‐year) were investigated. Sample. One hundred and thirty‐four physiotherapy students (61 first‐year and 73 second‐year). Methods. Design was 2×2 factorial with factors ‘Student Expertise’ (first‐year vs. second‐year) and ‘Model Expertise’ (expert vs. advanced student). Within expertise levels, students were randomly assigned to the Expert Example or the Advanced Student Example condition. All students studied two examples (content depending on their assigned condition) and then completed a retention and test task. They rated their invested mental effort after each example and test task. Results. Second‐year students invested less mental effort in studying the examples, and in performing the retention and transfer tasks than first‐year students. They also performed better on the retention test, but not on the transfer test. In contrast to our hypothesis, there was no interaction between student expertise and model expertise: all students who had studied the Expert examples performed better on the transfer test than students who had studied Advanced Student Examples. Conclusions. This study suggests that when worked examples are based on actual performance, rather than an ideal procedure, expert models are to be preferred over advanced student models. 相似文献

Providers of mental health services need tools to screen for acute psychosis and ultrahigh risk (UHR) for transition to psychosis in help-seeking individuals. In this study, the Eppendorf Schizophrenia Inventory (ESI) was examined as a screening tool and for its ability to correctly predict diagnostic group membership (e.g., help seeking, mild psychiatric complaints, highly symptomatic mood or anxiety disorder, UHR, acute psychosis). Diagnostic evaluation with established instruments was used for diagnosis in 3 research samples. UHR status was assessed with the Structured Interview for Prodromal Symptoms/Scale of Prodromal Symptoms (Miller et al., 1999) and the Bonn Scale for the Assessment of Basic Symptoms Prediction list (Gross, Huber, Klosterk?tter, & Linz, 1987; Klosterk?tter, Hellmich, Steinmeyer, & Schulze-Lutter, 2001). This study showed that members of different diagnostic groups rate themselves significantly differently on the ESI and its subscales. A new subscale was constructed, the UHR-Psychosis scale, that showed good utility in detecting individuals with interview-diagnosed UHR status and acute psychosis. The scale is also sensitive to the threshold between UHR and acute psychosis. Practical applications of the ESI include use as a diagnostic tool within various settings. 相似文献

How people's feelings change across time can be represented as trajectories in a core affect space defined by the dimensions of valence and activation. In this article, the authors analyzed individual differences in within-person affective variability defined as characteristics of core affect trajectories, introducing new ways to conceptualize affective variability. In 2 studies, participants provided multiple reports across time describing how they were feeling in terms of core affect. From these data, characteristics of participants' core affect trajectories were derived. Across both studies, core affect variability was negatively related to average valence, self-esteem, and agreeableness, and it was positively related to neuroticism and depression. Moreover, spin, a measure of how much people experienced qualitatively different feelings within the core affect space, was related more consistently to trait measures of adjustment and personality than other measures of within-person variability, including widely used measures of within-person single-dimension standard deviations. 相似文献

We investigated if responders accept a 50–50 split in a modified version of the ultimatum game, in which rejection yields a higher payoff (€7) than accepting the equal offer (€5). Therefore, the decision to accept the 50–50 split in this modified ultimatum game cannot be perceived as a self-interest act, as opposed to the standard game, in which acceptance may reflect resignation in the knowledge that the equal split is the best one can expect. A substantial proportion of responders accepts the equal split in this modified game (Study 1), which clearly establishes egalitarian preferences. Further studies show that the willingness to accept is not an artifact of indifference towards the extra payoff (Study 2), but reflects true concerns for proposers’ outcomes (Study 3). 相似文献

AbstractObjective: To assess levels of self-efficacy for health-related behaviour change and its correlates in patients with TIA or ischemic stroke.Methods: In this prospective cohort study, 92 patients with TIA or ischemic stroke completed questionnaires on self-efficacy for health-related behaviour change and fear, social support and depressive symptoms. Relations between fear, social support, depressive symptoms, cognitive impairment, vascular risk factors and history and demographic characteristics and low-self-efficacy were studied with univariable and multivariable logistic regression.Results: Median total self-efficacy score at baseline was 4 (IQR 4–5). Older age (OR 1.05, 95% CI 1.01–1.09), depressive symptoms (OR 1.09, 95% CI 1.03–1.16), presence of vascular history (OR 2.42, 95% CI 0.97–6.03), higher BMI (OR 1.15, 95% CI 1.01–1.30), fear (OR 1.06, 95% CI 1.01–1.12) and low physical activity (OR 1.49, 95% CI 1.01–2.21) were significantly associated with low self-efficacy.Conclusion: Patients with recent TIA or ischemic stroke report high self-efficacy scores for health-related behaviour change. Age, vascular history, more depressive symptoms, higher BMI, less physical activity and fear were correlates of low self-efficacy levels.Practice implications: These correlates should be taken into account in the development of interventions to support patients in health behaviour change after TIA or ischemic stroke. 相似文献

In this study, we used the lifespan theories of selection optimization and compensation (SOC) and the socio‐emotional selectivity theory (SST) to integrate the disengagement and activity perspectives on aging and to explain intra‐individual changes in work motivation. A two‐wave longitudinal survey study was conducted among 600 Dutch university employees to test relations between intra‐individual changes in subjective general health, future time perspective (FTP), and generativity and development motives. In line with the two lifespan theories, two processes were found. First, consistent with the disengagement perspective on aging, losses in subjective general health negatively predicted open‐ended FTP, and open‐ended FTP was positively associated with an increase in growth motives. Secondly, consistent with the activity perspective on aging, losses in subjective general health positively predicted limited FTP, and limited FTP was positively associated with an increase in generativity motives. In addition, initial open‐ended FTP predicted future open‐ended FTP through a change in subjective general health. Finally, these relations were found to differ across age groups, and thus over the lifespan. More specifically, losses in subjective general health and increases in limited FTP particularly result in lower development motives and higher generativity motives among middle‐aged workers, indicating that interventions aimed at preventing losses in health are probably most effective for maintaining development motives in this group. 相似文献

The Leader-Member exchange (LMX) theory of leadership states that leaders do behave differently towards the various members in their work unit. Relatively little attention has been devoted to the question of whether members' perceptions of differential treatment on the part of the leader affects their commitment to the work unit. Perceptions of the amount of differential treatment within their work unit did not explain additional variance in members' work unit commitment after the effects of LMX quality were accounted for. There was, however, a significant interaction effect of LMX quality and differential treatment on work unit commitment. The perception of a large number of differential treatment incidents seems to act as a neutralizer with respect to the positive effects LMX quality may have. 相似文献
