In this paper, we address the use of Bayesian factor analysis and structural equation models to draw inferences from experimental psychology data. While such application is non-standard, the models are generally useful for the unified analysis of multivariate data that stem from, e.g., subjects’ responses to multiple experimental stimuli. We first review the models and the parameter identification issues inherent in the models. We then provide details on model estimation via JAGS and on Bayes factor estimation. Finally, we use the models to re-analyze experimental data on risky choice, comparing the approach to simpler, alternative methods. 相似文献

This study aims to evaluate the prevalence of depression and anxiety and investigate the potential risk factors for depression and anxiety in Chinese gout patients. A self-report survey was administered to 226 gout patients and 232 age- and gender-matched healthy individuals. Patients were asked to complete a set of standardized self-report questionnaires. Univariate and mutiple regression were used to analyze the data. We found 15.0% of gout patients had depression, and 5.3% had anxiety. After adjusted demographic variables, the prevalence of depression was significantly higher than the healthy controls (6.0%). There were significant correlations among education, total pain, disease duration, stage of gout, functional disability, number of tophi, number of flares/last year, presence of tender joints, nephropathy comorbidity, health-related quality of life (HRQoL), and psychological status. Meanwhile, logistic regression analysis identified number of tophi, functional disability, and mental component summary (MCS) as predictors of depression in gout patients. Education and MCS were significantly accounted for anxiety. In summary, the prevalence of depressive symptoms among gout patients was higher than healthy individuals. Education, disability, tophi and HRQoL were important risk factors linked to depression/anxiety in Chinese gout population. 相似文献

Research has indicated that clinical serious disease may lead to posttraumatic growth (PTG). However, little is known about PTG among hemodialysis (HD) patients. The study examined the relationship among resilience, rumination and PTG among Chinese HD patients. 196 HD patients were recruited from a tertiary hospital in a Northern city of China between 1 June 2015 and 30 May 2016. Patients were surveyed using the Posttraumatic Growth Inventory-Chinese version, Connor-Davidson Resilience Scale, and Chinese Event Related Rumination Inventory. Correlation analyses showed that resilience was most highly positively correlated with PTG (r = .70, p < .001), deliberate rumination moderately correlated to PTG (r = .50, p < .001), and intrusive rumination was lower negatively related to PTG (r = –.26, p < .001). Regression analyses showed that age, gender, duration of dialysis, resilience and deliberate rumination had significant associations with PTG (β = ?.31, p < .0001; β = –.14, p = .002; β = .10, p = .032; β = .44, p < .001; β = .20, p < .001). They together explained 65% of the total variance in PTG (F [8,195] = 46.74, p < .001). However, intrusive rumination was not associated with PTG (p > .05). The results suggested that resilience and deliberate rumination may be instrumental for PTG improvement. 相似文献

The present study aimed to examine the effects of attachment, social support and resilience on posttraumatic stress disorder (PTSD) symptoms in people living with HIV/AIDS. One hundred fifty-two HIV+ adults in China were investigated. The results suggested that attachment anxiety had a significant direct effect on PTSD symptoms and impacted PTSD symptoms indirectly though associations with social support and resilience. Attachment avoidance could also be considered a distal risk factor of PTSD symptoms via the mediation of social support and resilience. The findings highlight the importance of identifying trauma and PTSD symptoms in people affected by HIV/AIDS and suggest that people with attachment anxiety and low social support resources might be at high risk for PTSD. 相似文献

Research with Native Americans has identified connectedness as a culturally based protective factor against substance abuse and suicide. Connectedness refers to the interrelated welfare of the individual, one's family, one's community, and the natural environment. We developed an 18-item quantitative assessment of awareness of connectedness and tested it with 284 Alaska Native youth. Evaluation with confirmatory factor analysis and item response theory identified a 12-item subset that functions satisfactorily in a second-order four-factor model. The proposed Awareness of Connectedness Scale (ACS) displays good convergent and discriminant validity, and correlates positively with hypothesized protective factors such as reasons for living and communal mastery. The measure has utility in the study of culture-specific protective factors and as an outcomes measure for behavioral health programs with Native American youth. 相似文献

Knowledge-sharing intention in a virtual community: a study of participants in the Chinese Wikipedia
This study proposes a model for evaluating virtual community members' knowledge-sharing intention toward Chinese Wikipedia. The results of this study reveal that knowledge-sharing intention is influenced directly by attitude, subjective norms, and perceived behavioral control, whereas anticipated reciprocal relationships and enjoying helping are positively related to attitude; sense of self-worth and peer influences are positively related to subjective norms; and self-efficacy and resource-facilitating conditions are positively related to perceived behavioral control on knowledge sharing. 相似文献

This study compared Lower Quarter Y-Balance Test (YBT-LQ) performance and leg muscle kinetics between children with and without developmental coordination disorder (DCD), and investigated the association between YBT-LQ performance and muscle kinetics in children with DCD. Forty-eight children with DCD and 51 children without DCD participated in the study. Leg muscle kinetics were measured using surface electromyography when performing YBT-LQ. Children with DCD exhibited an overall lower YBT-LQ scores than controls. They had a lower peak gastrocnemius medialis activation for YBT-LQ posteromedial direction and shorter duration for the muscle to reach peak torque for YBT-LQ anterior direction. No relationship was found between YBT-LQ performance and leg muscle activations in children with DCD. Children with DCD exhibited a less competent YBT-LQ performance with atypical neuromuscular control. 相似文献
