Effect of self-control on health promotion behavior in patients with coronary heart disease: mediating effect of ego-depletion.

The present study used a cross-sectional survey design to explore the role of ego-depletion in the relationship between self-control and health-promoting behaviors in patients with coronary heart disease (CHD). This study recruited 277 patients with CHD to measure the levels of ego-depletion, self-control and health-promotion (HP) behavior using Self-Regulatory Fatigue Scale (SRF-s), Dual-Mode of Self-Control Scale (DMSD-s) and Health Promotion Lifestyle Profile-II (HPLP-II) to examine the relationship between the three. Study found that self-control improved the patients' HP behaviors to some extent. Self-control in patients with CHD uses ego-depletion as the mediating variable to indirectly and positively predict the level of HP behavior, and the mediating effects account for 47.76% (impulsive system) and 15.6% (control system) of the total effects, respectively.

[Psychological resilience features of urban migrant children and rural left-behind children in Sichuan province of China].

OBJECTIVE: To explore the characteristics of resilience of urban migrant children and rural left-behind children of Chinese farmer workers and to figure out the discrepancy between them. METHODS: The samples consisted of 1 391 primary students and middle school students from Chengdu, Guangyuan, Yibin, and Mianyang in Sichuan Province. The revised version of the Healthy Kids Resilience Assessment was used for the measurement of resilience. And ANOVA was performed for data analysis. RESULTS: The results of the present study indicated that among all the junior high students, urban migrant children got a significantly lower score of resilience (128.11±21.70) than rural left-behind children (135.61±22.77) and the control group (132.87±23.22), F(0.05 (2, 884))=8.076, P<0.001. And migrant children got lower scores on three external protective factors of resilience-family, school, community as well as on resilience traits than left-behind children and the control group (Family: F(0.05(2, 884))=7.820, P<0.001; School: F(0.05(2, 884))=5.041, P=0.007; Community: F(0.05(2, 884))=9.261, P<0.001; Resilience traits: F(0.05(2, 884))=3.510, P=0.030). No significant difference was noted between left-behind children and control group. Gender difference and grade difference were noted for each group. CONCLUSION: The resilience of migrant children was not so good as non-migrant children. Migrant children were enjoying less intimate interpersonal relationship in their schools, their families as well as their community, and they could get less psychological support from the external environment, so that migrant children could not develop some resilience traits to promote the sound development of themselves. Suggestions for intervention were also discussed.
