The multilevel logistic regression model (M-logit) is the standard model for modeling multilevel data with binary outcomes. However, many assumptions and restrictions should be considered when applying this model for unbiased estimation. To overcome these limitations, we proposed a multilevel CART (M-CART) algorithm which combines the M-logit and single level CART (S-CART) within the framework of the expectation-maximization. Simulation results showed that the proposed M-CART provided substantial improvements on classification accuracy, sensitivity, and specific over the M-logit, S-CART, and single level logistic regression model when modeling multilevel data with binary outcomes. This benefit of using M-CART was consistently found across different conditions of sample size, intra-class correlation, and when relationships between predictors and outcomes were nonlinear and nonadditive. 相似文献

Pregnancy and the early post partum period are widely understood as a critical period for the infant’s emotional development and the earliest influence shaping social interaction. The present study aims to understand the potential influence of both antenatal and postnatal maternal anxiety and depressive symptoms on socio-emotional outcomes in offspring aged 12 months. The study used longitudinal data from a prospective cohort study on Australian pregnant women and their children. Data were available for 282 mothers and their children. Maternal depressive and anxiety symptoms were measured in early pregnancy, trimester three of pregnancy, six and 12 months postpartum. Social and emotional development in children was measured using the Brief Infant and Toddler Social Emotional Assessment (BITSEA) at 12 months. Using growth curve analysis of 4 waves of repeated measurement to examine intercept and slope, we found that both initial maternal depression and anxiety symptom levels, and the growth of these symptoms over time, predicted more problems with children’s social and emotional development. In the final model anxiety accounted for 19% of the variance in child socio-emotional problems and depression 23% of variance. The results emphasise the importance of perinatal maternal mental health as a potential risk factor for child development. This carries important implications for policy development, such as the need to build early identification and early intervention models in to the current clinical practice for perinatal care, specifically, to develop targeted screening, assessment and interventions to address maternal mental health issues for at-risk parents during pregnancy, and continuing monitoring of young children whose mothers have experienced perinatal mental health difficulties. 相似文献

The social investment theory (SIT) proposes that personality maturation is triggered by transitions into age‐graded roles and psychological commitment to these roles. The present study examines the predictions of SIT by focusing on the transition from student life to working life. We analysed three‐wave longitudinal data and compared participants who made the transition into working life (N = 226), participants who combined education with work (N = 387), and participants who did not make the transition at all (N = 287). In contrast to the predictions of SIT, we found no differences in personality maturation between individuals who made the transition into working life and those who did this only partly or not at all. Psychological commitment to work did not explain individual differences in personality maturation for those who made the transition (partly) into working life after controlling for multiple testing. Therefore, the present study did not support the predictions of SIT. © 2019 The Authors European Journal of Personality published by John Wiley & Sons Ltd on behalf of European Association of Personality Psychology 相似文献

IntroductionThe dark side of affective commitment has been ignored in the past literature on organizational commitment.ObjectivesUsing the tenants of moral self-licensing theory, we examined how affective commitment can cause negative outcomes. We hypothesized that affective commitment leads to unethical pro-organizational behaviors, careerism and counter-productive work behaviors through increased urge for status striving.Methods and resultsA multi-wave and two-source data was obtained (n = 306) from employees and their peers working in the service sector of Pakistan. Employing structural equation modelling (SEM) analysis our results indicate that high levels of affective commitment might unleash status striving which further creates unethical pro-organizational behaviors, careerism and CWBs.ConclusionThe current study opens up a new side in the affective commitment literature by examining status striving as an underlying mechanism through which affective commitment reveals its deleterious consequences for employees. 相似文献

Deeply rooted U.S. cultural practices and legislative processes have facilitated the dissociation, erasure, and evasion of engagement with mixed-race subjectivities. As multiracial clinicians, we attempt to reexamine the discourse around race in psychoanalytic literature, questioning the process by which dominant monoracial norms have been constructed, reproduced, and codified as normal and acceptable. We propose that the absence of multiracial subjectivities from the psychoanalytic literature reflects a broader social discomfort with and cultural dissociation of the mixed-race experience. We further suggest that it is necessary to engage both analytically and queer-ly with the subjective experience of racial multiplicity—positing that multiracial subjectivities might best be understood as subjectivities that are “racially queer.” 相似文献

This study aimed to validate measures of work engagement, job satisfaction, psychological empowerment, and organisational citizenship for use with employees in a mining enterprise in Zimbabwe. Miners (N = 176, males = 85.2%, females = 1.3%; age range = 24–65 years; general workers = 92%) completed the Utrecht Work Engagement Scale (UWES), the Psychological Empowerment Scale (PES), the Minnesota Job Satisfaction Questionnaire (MSQ20), and Organisational Citizenship Behaviour Checklist (OCB-C20). Findings, following exploratory factor analysis, suggest scores from the UWES, PES, MSQ20, and OCB20 to be reliable for research purposes in the Zimbabwean mining sector setting. 相似文献

An action research using three classical models of occupational stress enabled us to verify the impact on the results obtained from the choice of model and paradigm: psychosocial risks versus Quality of work life. Four hundred and thirty-six supermarket employees answered a questionnaire including these three measures of stress, the outcomes (satisfaction, fatigue) and a possible cause (role strain). Our results validate the hypotheses of significant differences in stress prevalence levels according to the model, such as links to the factor and the consequences, as well as the importance of the perception of stress to explain the negative experience. 相似文献

Based on broaden-and-build theory, this study proposes to expand the happy-productive worker thesis by exploring an emergent operationalization of happiness. To do so, the mediating effect of the dimensions of psychological well-being at work (i.e., relation to oneself, to others and to work) on the relation between resilience and task performance has been tested. A total of 280 Quebec workers filled out validated measures. Obtained by structural equation modelling analyses, the results indicate that the rapport with oneself of psychological well-being at work acts as the only mediator between resilience and task performance. These findings underscore the importance of encouraging the development of interventions that build on the resilience and positive experience of workers to optimize their work performance. 相似文献

Within current neoliberal discourses, critical reflection provides opportunity for innovation in social work practice. This article describes a thinking aloud process used with supervisor–supervisee dyads in community-based child welfare social work to assist critical reflection via the use of open-ended questioning and inquiry. The strength of thinking aloud permitted a deeper appreciation of how the supervision session is utilised to reflect on practice and provided a learning tool within supervision. The feedback from the dyads concurred that thinking aloud assisted in stimulating reflection, developing solutions to the key issues discussed, and was transformative in recognising areas for future development. The process of thinking aloud supports the opportunity and space for the supervisor and supervisee to articulate meaning, critically develop insight, reconstruct, and transport this into future practice. Thinking aloud offers an example of how knowledge can be co-constructed by practitioners within practice and critical reflection captured within qualitative research approaches. 相似文献
