Objective This study aimed at assessing the self-management activities of type 2 diabetes patients using Structural Equation Modeling (SEM) which measures and analyzes the correlations between observed and latent variables. This statistical modeling technique explored the linear causal relationships among the variables and accounted for the measurement errors. Methods A sample of 200 patients was recruited from the middle-aged population of rural areas of Pakistan to explore the self-management activities of type 2 diabetes patients using the validated version of the Urdu Summary of Diabetes Self-care Activities (U-SDSCA) instrument. The structural modeling equations of self-management of diabetes were developed and used to analyze the variation in glycemic control (HbA1c). Results The validated version of U-SDSCA instrument showed acceptable psychometric properties throughout a consecutive reliability and validity evaluation including: split-half reliability coefficient 0.90, test-retest reliability (r = 0.918, P  ≤ .001), intra-class coefficient (0.912) and Cronbach’s alpha (0.79). The results of the analysis were statistically significant (α = 0.05, P-value < .001), and showed that the model was very well fitted with the data, satisfying all the parameters of the model related to confirmatory factor analysis with chi-squared = 48.9, CFI = 0.94, TLI = 0.95, RMSEA = 0.065, SPMR = 0.068. The model was further improved once the items related to special diet were removed from the analysis, chi-squared value (30.895), model fit indices (CFI = 0.98, TLI = 0.989, RMSEA = 0.045, SPMR = 0.048). A negative correlation was observed between diabetes self-management and the variable HbA1c (r = –0.47; P < .001). Conclusions The Urdu Summary of Diabetes Self-Care Activities (U-SDSCA) instrument was used for the patients of type 2 diabetes to assess their diabetes self-management activities. The structural equation models of self-management showed a very good fit to the data and provided excellent results which may be used in future for clinical assessments of patients with suboptimal diabetes outcomes or research on factors affecting the associations between self-management activities and glycemic control

The Relationship

The aim of this research is to identify the relationship between online sale and customer value co-creation. In addition, to identify the mediating role of E-Satisfaction and E-Trust in the relationship between the online sale and customer value co-creation. This study selected a sample of 364 customers who shopped from the Modanisa website in Jordan, and a structural equation modeling (SEM) approach was applied in this study to suit the nature of the study and to achieve the desired goals. This approach is based on showing the variables' relationship with each other. In this study, the relationship between online sale and customer value co-creation was influenced by E-trust and E-satisfaction. As per the results have indicated the foregoing, the analysis exhibited a favorable relation between them. E-trust impacts online sale and customer value relationship CO-creation, E-satisfaction affects the connection between the customer and online sales value. In addition, this study proves that online transactions contribute to the CO-creation of customer value for Modanisa. The customer value of CO-creation is, however, influenced by online purchases by E-trust and E-satisfaction in the Modanisa site. The findings of the study show that consumers with the higher online sale are far more committed to rising customer value by enhancing E-trust and E-satisfaction.

Positive Effect

Leader humor plays an important role in organizations because it affects employees' attitude and behavior. The positive effect of humor in organizations has been widely touted; however, research on the effect of leader humor on employee creativity is still rare. This study addressed how leader positive humor affects employee creativity and whether work engagement mediates this relationship. Data were collected from 233 supervisor–subordinate dyads in 23 Chinese hightech companies. Results of structural equation modeling indicate that leader positive humor was positively related to work engagement, and that work engagement was positively related to employee creativity. Additionally, work engagement mediated the relationship between leader positive humor and employee creativity. Thus, organizations should encourage managers to use positive humor to enhance employees' engagement at work, which will, in turn, lead to creative outcomes. This research extends understanding of the leader positive humor–employee creativity relationship.

The Relationship

The purpose of this study was to provide a better understanding of the link between selforiented perfectionism and academic procrastination by examining the role of self-efficacy as a mediator in the relationship. We explored the preliminary model and the competitive model. To examine these two models, we collected the survey results of 692 college students and employed structural equation modeling. The results of this study showed that students with high self-oriented perfectionism procrastinated less than others. It was also found that self-efficacy fully, rather than partially, mediated the relationship between self-oriented perfectionism and academic procrastination. Implications of this study are discussed.

The Relationship

Objective: There are few studies about the relationship between social capital (SC) and depression among type 2 diabetes mellitus (T2DM) patients, and the mechanism explaining how SC leads to decreased depression is unclear. The current study aims to explore the relationship between SC and depressive symptoms among the T2DM patients in northwest China, with a particular focus on the mediating role of sleep quality.Methods: A cross-sectional study of 1,761 T2DM patients from Ningxia Province was conducted. The Center for Epidemiological Survey Depression Scale (CES-D) and self-report sleep quality questionnaire coupled with the SC scales were administered during the face-to-face survey. The Bootstrap methods PROCESS program is employed to test the mediation model.Results: The prevalence of depressive symptoms among T2DM patients was 24.8%. After controlling for covariates, the SC (r = −0.23, p &lt; 0.001) was negatively correlated with CES-D score; the sleep quality was also negatively correlated with CES-D score (r = −0.31, p &lt; 0.001); and the SC was positively correlated with sleep quality (r = 0.10, p &lt; 0.001). Logistic regression analysis showed that SC was inversely related to the risk of depressive symptoms. Meanwhile, sleep quality was negatively associated with depressive symptoms. Sleep quality has mediated the relationship between SC and depressive symptoms among T2DM patients (explaining 12.6% of the total variance).Conclusions: We elucidated how SC interacted with depressive symptoms through the mediation pathway of sleep quality using a representative sample of the Chinese diabetes patients. The findings indicate that the improvement of SC and sleep quality may help in maintaining mental health among T2DM patients. Hence, clinicians can suggest that patients communicate more with others to improve the SC and, in turn, maintain their health.
