The mediation effect of health literacy on social support and health lifestyle of patients with chronic diseases.

BACKGROUND: Previous studies have identified the antecedents of the lifestyle of many patients with chronic diseases. However, the mechanism of social support affecting the lifestyle of patients with chronic diseases is unclear, and the role of health literacy in social support affecting the lifestyle of patients with chronic diseases has not been found. Therefore, this study aims to explore the status quo of social support, health literacy and healthy lifestyle of patients with chronic diseases in China and the relationship among them. METHODS: Through convenient sampling, 356 patients with chronic diseases were surveyed using a health promoting lifestyle scale, a chronic disease patients' health literacy scale and a social support scale. RESULTS: There was a pairwise positive correlation between social support, health lifestyle and health literacy (R = 0.397,0.356,0.556, P < 0.01). After controlling gender, age and education level, it is found that social support has a positive impact on health lifestyle, and health literacy plays an intermediary role between social support and health lifestyle, accounting for 45.78 % of the total effect. CONCLUSION: To promote the healthy lifestyle of patients with chronic diseases and delay the development of the disease, we should strengthen social support for patients with chronic diseases; We should simultaneously take various measures to improve their health literacy.

Exploring the relationship between social exclusion and social media addiction: The mediating roles of anger and impulsivity.

Previous studies have examined the relationships between some antecedents and social media addiction. However, an important factor - social exclusion - has not received enough attention in the literature, the underlying psychological mechanisms that link social exclusion to social media addiction are still unclear. The current study investigated the relation between social exclusion and social media addiction as well as the mediating effects of anger and impulsivity on this relationship. An online survey was conducted, the sample included 573 university students (323 females). The results suggested that: (1) social exclusion was positively correlated with social media addiction; (2) anger and impulsivity separately mediated the relation between social exclusion and social media addiction; and (3) anger and impulsivity sequentially mediated the association between social exclusion and social media addiction. The results of the present study were conducive to understanding the associations and the psychological mechanisms between the study variables.

Exploring the relationship between mental health literacy and psychological distress in adolescents: A moderated mediation model.

Previous studies on the relationship between mental health literacy and psychological distress were rich, but little was known about the influence mechanism between them, and almost no research was found on the role of psychological resilience and subjective socio-economic status in the relationship between them. This study used a moderated mediation model to test the mediating effect of psychological resilience on the relationship between mental health literacy and psychological distress, and the moderating effect of subjective socioeconomic status in Chinese adolescents. We investigated 700 junior high school students in Inner Mongolia, China through online survey. The results are as follows: (1) Mental health literacy is a negative predictor of adolescents' psychological distress; (2) psychological resilience mediated the association between mental health literacy and psychological distress; (3) The first half of the model, that is, the relationship between mental health literacy and psychological resilience, is moderated by subjective socioeconomic status. Specifically, for adolescents with low subjective socioeconomic status, the positive predictive effect of mental health literacy on psychological resilience is obviously enhanced. The current findings would contribute to a deep understanding of the relationship among adolescents' mental health literacy, psychological resilience, subjective socioeconomic status and psychological distress, which may be of great significance to the prevention of adolescents' psychological distress.

Short version of the smartphone addiction scale: Measurement invariance across gender.

The Smartphone Addiction Scale Short Version (SAS-SV) has been widely used in research, but little is known about the measurement invariance across gender. The current study measured SAS-SV invariance between male and female college students in a sample of 1112 participants. Single- and multiple-group confirmatory factor analyses (CFAs) of smartphone addiction symptom ratings were conducted using R program with RStudio. SAS-SV was psychometrically robust in measuring the severity of smartphone addiction among college students, as well as the gender-based invariance. The differences in SAS-SV between male and female participants were likely to represent true gender differences, and meaningful comparisons could be made.

Exploring the relationship between social exclusion and smartphone addiction: The mediating roles of loneliness and self-control.

Previous studies have identified many antecedents of smartphone addiction. However, social exclusion as a risk factor for smartphone addiction has not been widely studied, and little is known concerning the psychological mechanism underlying this association. The present study tested the influence of social exclusion on smartphone addiction as well as the mediating roles of loneliness and self-control in this relationship. An online survey was conducted, and the sample consisted of 573 university students (323 females). The results revealed that (1) social exclusion was a positive predictor of smartphone addiction; (2) loneliness and self-control separately mediated the association between social exclusion and smartphone addiction; and (3) loneliness and self-control sequentially mediated the relation between social exclusion and smartphone addiction. Possible explanations were discussed. The findings of the current study would contribute to understanding the relationships between these study variables as well as the psychological mechanisms underlying these associations.

Measurement Invariance of the Bergen Social Media Addiction Scale Across Genders.

Social media addiction has been a hot issue in scientific research in recent years, its antecedents and consequences have been extensively studied. Among these studies, Bergen Social Media Addiction Scale (BSMAS) is one of the most commonly used instruments. However, little is known about whether this scale has the equivalent psychometric properties for men and women. The purpose of the current study is to examine the measurement invariance (including configural invariance, metric invariance, scalar invariance, and error variance invariance) of the BSMAS across genders. In total, 1,120 participants were recruited from 5 universities. R program was applied to conduct the single-group and multiple-group confirmatory factor analysis (CFA) based on the social media addiction symptom ratings. The results demonstrated that BSMAS was a valid and psychometrically robust instrument for assessing the risk of social media addiction among university students, and that the four types of measurement invariance of the BSMAS across genders were confirmed. Consequently, gender differences in the BSMAS scores are likely to reflect the genuine differences between men and women, and comparisons on the level of social media addiction of university students between gender groups can be interpreted meaningfully.

Regulatory emotional self-efficacy and psychological distress among medical students: multiple mediating roles of interpersonal adaptation and self-acceptance.

BACKGROUND: Psychological distress (depression, anxiety and stress) is more common among medical students than in the general population, and is an important cause of insomnia, internet addiction, substance abuse, decreased academic performance and increased suicidality in medical students. METHODS: To examine the mechanism by which regulatory emotional self-efficacy affects medical students' psychological distress, a questionnaire of 539 medical students using an interpersonal adaptability scale, regulatory emotional self-efficacy scale, self-acceptance scale and depression-anxiety-stress scale was conducted. RESULTS: ① Regulatory emotional self-efficacy, interpersonal adaptability and self-acceptance are positively correlated, but they are negatively correlated with psychological distress. ② The mediation model shows that interpersonal adaptation and self-acceptance are the mediation variables of the effect of regulatory emotional self-efficacy on psychological distress, and the total mediation effect value is -0.37, accounting for 86.05% of the total effect (-0.43). Specifically, the effect involves three paths: first, regulatory emotional self-efficacy indirectly affects psychological distress through interpersonal adaptation (effect value-0.24); second, regulatory emotional self-efficacy indirectly affects psychological distress through interpersonal adaptation and self-acceptance (effect value-0.08); and third, regulatory emotional self-efficacy indirectly affects psychological distress through self-acceptance (effect value -0.05). CONCLUSIONS: Interpersonal adaptation and self-acceptance have a significant mediating effect between regulatory emotional self-efficacy and psychological distress, and the chain mediating effect of interpersonal adaptation and self-acceptance is also significant.

The relationships between negative emotions and latent classes of smartphone addiction.

The relationships between negative emotions and smartphone addiction has been tested through the literature. However, most of the studies applied variable-centered approaches. The heterogeneity of smartphone addiction severity has not been examined for the associations with negative emotion variables. The purposes of the present study is to explore the latent classes of smartphone addiction and analyze the relationships between depression, social anxiety and boredom and these subgroups. The Smartphone Addiction Scale-Short Version (SAS-SV) and three negative emotion scales were employed to conduct a survey of 539 college students. Mplus8.3 software was applied to perform the latent class analysis (LCA) based on the smartphone addiction symptom ratings. ANOVA and multinomial logistic regression were used to explore the differences among these latent categories and the associations between these subgroups and negative emotion variables. Results demonstrated that Negative emotional variables were significantly correlated with smartphone addiction proneness. Based on their scores on the Smartphone Addiction Scale, smartphone users were divided into three latent classes: low risk class, moderate class and high risk class. Women were more likely to be classified in the high-risk class. The severity of depression and boredom was able to predict the membership of the latent class effectively; while social anxiety failed to do this in the high risk class.

Cross-cultural validity of the theory of planned behavior for predicting healthy food choice in secondary school students of Inner Mongolia.

AIMS: Unhealthy eating behavior is a serious health concern among secondary school students in Inner Mongolia. To predict their healthy food choices and devise methods of correcting unhealthy choices, we sought to confirm the cross-cultural validity of the theory of planned behavior among Inner Mongolian students. MATERIALS AND METHODS: A cross-sectional study, conducted between November and December 2014. Overall, 3047 students were enrolled. We devised a questionnaire based on the theory of planned behavior to measure its components (intentions, attitudes, subjective norms, and perceived behavioral control) in relation to healthy food choices; we also assessed their current engagement in healthy food choices. RESULTS: A principal component analysis revealed high contribution rates for the components (69.32%-88.77%). A confirmatory factor analysis indicated that the components of the questionnaire had adequate model fit (goodness of fit index=0.997, adjusted goodness of fit index=0.984, comparative fit index=0.998, and root mean square error of approximation=0.049). Notably, data from participants within the suburbs did not support the theory of planned behavior construction. Several paths did not predict the hypothesis variables. However, attitudes toward healthy food choices strongly predicted behavioral intention (path coefficients 0.49-0.77, p<0.01), regardless of demographic characteristics. CONCLUSION: Our results support that the theory of planned behavior can apply to secondary school students in urban areas. Furthermore, attitudes towards healthy food choices were the best predictor of behavioral intentions to engage in such choices in Inner Mongolian students.
