The associations between smartphone addiction and self-esteem, self-control, and social support among Chinese adolescents: A meta-analysis.

Background: Smartphone addiction has become a social problem that affects the healthy growth of adolescents, and it is frequently reported to be correlated with self-esteem, self-control, and social support among adolescents. Methods: A meta-analysis was conducted by searching the PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP) databases. Stata 16.0 was used to analyse the overall effect and test the moderating effect. Results: Fifty-six studies were included, involving a total of 42,300 participants. Adolescents' smartphone addiction had a moderately negative correlation with self-esteem (r = -0.25, 95% CI = -0.29 to -0.22, p < 0.001), a strong negative correlation with self-control (r = -0.48, 95% CI = -0.53 to -0.42, p < 0.001), and a weak negative correlation with social support (r = -0.16, 95% CI = -0.23 to -0.09, p < 0.001). Moderation analysis revealed that the correlation between adolescents' smartphone addiction and self-esteem was strongest when smartphone addiction was measured with the Mobile Phone Addiction Tendency Scale for College Students (MPATS; r = -0.38). The correlation between adolescents' smartphone addiction and self-control was strongest when self-control was measured with the Middle school students' Self-control Ability Questionnaire (MSAQ; r = -0.62). The effect of dissertations on smartphone addiction, self-control, and social support among adolescents was significantly larger than that of journal articles. The correlation between adolescents' smartphone addiction and social support was strongest when smartphone addiction was measured with the Mobile Phone Addiction Index (MPAI; r = -0.24). However, the correlations between adolescents' smartphone addiction and self-esteem, self-control, and social support were not affected by age or gender. Conclusion: There was a strong relationship between smartphone addiction and self-esteem, self-control, and social support among adolescents. In the future, longitudinal research should be carried out to better investigate the dynamic changes in therelationship between smartphone addiction and self-esteem, self-control, and social support.

Correlations between smartphone addiction and alexithymia, attachment style, and subjective well-being: A meta-analysis.

Background: Smartphone addiction (SA) has become a social problem that affects peoples' quality of life and is frequently reported to be correlated with alexithymia, avoidant or anxious attachment styles, and subjective well-being. This study aimed to investigate the relationship between SA and alexithymia, attachment style, and subjective well-being. Methods: A meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following electronic databases were searched: PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP). Stata 16.0 was used to analyze the overall effect and test the moderating effect. Results: One hundred and ten studies were included, involving a total of 96,680 participants. SA had a significantly high positive correlation with alexithymia (r = 0.40), attachment anxiety (r = 0.37), and negative emotions (r = 0.31), and a low positive correlation with attachment avoidance (r = 0.17). In addition, there was a high negative correlation between SA and subjective well-being (r = -0.33) and a low negative correlation between SA, life satisfaction (r = -0.17), and positive emotions (r = -0.18). A moderation analysis revealed that age significantly moderated the relationship between SA and positive emotions. The tools for measuring SA significantly moderated the relationship between SA, alexithymia, attachment anxiety, and subjective well-being. Meanwhile, subjective well-being measurement tools significantly moderated the relationships between SA, subjective well-being, and negative emotions. Conclusion: SA was closely related to alexithymia, attachment style, and subjective well-being. In the future, longitudinal research can be conducted to better investigate the dynamic changes in the relationship between them.

Professional identity and emotional labour affect the relationship between perceived organisational justice and job performance among Chinese hospital nurses.

AIM: To investigate the influence of perceived organisational justice, professional identity and emotional labour on nurses' job performance. BACKGROUND: Previous studies have not explored the impact of professional identity and emotional labour on the relationship between perceived organisational justice and job performance. However, how to mobilize the enthusiasm of nurses and improve their job performance is the key for nursing managers to realize the sustainable development of hospitals. METHODS: A cross-sectional survey design was conducted. A total of 951 nurses from public hospitals in China participated in the survey from March-June 2021. The descriptive statistical approach, Pearson's correlation analysis and the PROCESS Macro Model 4 and 14 in regression analysis were used to analyse the available data. RESULTS: The results showed that nurses' perceived organisational justice, professional identity, emotional labour and job performance were significantly positive correlations between every two variables, with coefficients ranging between .24 and .75. Professional identity played a whole mediating role in perceived organisational justice and job performance, accounting for 98.04% of the total effect; meanwhile, this process was moderated by emotional labour. CONCLUSIONS: Perceived organisational justice positively predicted nurses' job performance; as a mediating mechanism with moderating, professional identity and emotional labour further explained how perceived organisational justice promoted the job performance of nurses. IMPLICATIONS FOR NURSING MANAGEMENT: This study highlighted the moderated mediation role of professional identity and emotional labour between nurses' perceived organisational justice and job performance. Understanding this mechanism has guiding significance for nursing managers to improve nurses' job performance.

Effects of music therapy on anxiety: A meta-analysis of randomized controlled trials.

This study aims to evaluate the efficacy of music therapy on anxiety from randomized controlled trials (RCTs). The following electronic databases were utilized for selecting eligible studies that were published from inception to March 2021: PubMed, Cochrane Library, PsycINFO, Medline, Web of Science, and Embase. Standard mean difference (SMD) with 95% confidence interval (CI) values were used to evaluate the efficacy of music therapy on anxiety. Thirty-two studies with 1,924 participants were included in the meta-analysis. Music therapy lasted an average of 7.5 sessions (range, 1-24 sessions), while the average follow-up duration was 7.75 weeks (range, 1-16 weeks). Music therapy significantly reduced anxiety compared to the control group at post-intervention (SMD = -0.36, 95% CI: -0.54 to -0.17, p < 0.05), but not at follow-up (SMD = -0.23, 95% CI: -0.53 to 0.08, p >0.05). Subgroup analysis found a significantly positive effect of music therapy on anxiety in < 60 and ≥ 60 age-group (SMD = -0.31, 95% CI: -0.52 to -0.09, p < 0.05; SMD = -0.45, 95% CI: -0.85 to -0. 05, p < 0.05), developed and developing country group (SMD = -0.28, 95% CI: -0.51 to -0.06, p < 0.05; SMD = -0.49, 95% CI: -0.80 to -0.17, p < 0.05), < 12 and ≥ 12 sessions group (SMD = -0.24, 95% CI: = -0.44 to -0.03, p < 0.05; SMD = -0.59, 95% CI: -0.95 to -0.22, p < 0.05), respectively. Our study indicated that music therapy can significantly improve anxiety during treatment. But given that only eight RCTs reported the effects of music therapy at follow-up and the duration of follow-up was inconsistent, further researches are needed on the lasting effects after the intervention is discontinued.

The effect of remote peer support on stigma in patients after breast cancer surgery during the COVID-19 pandemic: A protocol for systematic review and meta-analysis.

BACKGROUND: Patients after breast cancer surgery have a high sense of stigma due to the formation of surgical scars, loss of breast shape or other reasons, leading to anxiety, depression, and other adverse mental health problems, thus reducing their quality of life. Remote peer support intervention based on telephone, internet or email is low-cost and easy to spread, and protects patients' privacy, solves the barriers to access that many patients face when attending face-to-face programs. Therefore, remote peer support may be an effective way to reduce stigma and improve mental health in patients after breast cancer surgery during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Eight databases (PubMed, Embase, Cochrane Library, CNKI, PsycNET, MEDLINE, Psychology & Behavioral Sciences Collection and Web of Science) will be used to select eligible studies that were published from inception to May, 2021. The eligible studies will be screened, extracted and then the methodological quality will be evaluated independently by 2 reviewers. Review manager software version 5.3 software and Stata version 14.0 software will be used for meta-analysis. RESULTS: The results of this study will show the effect of remote peer support on stigma, depression and anxiety in patients after breast cancer surgery during the COVID-19 pandemic and will be submitted to a peer-reviewed journal for publication. CONCLUSION: The results of this study will provide evidence for the effectiveness of remote peer support in patients after breast cancer surgery during the COVID-19 pandemic.

The effectiveness of peer support on self-efficacy and self-management in people with type 2 diabetes: A meta-analysis.

OBJECTIVES: This study aims to investigate the effectiveness of peer support on self-efficacy and self-management in people with type 2 diabetes. METHODS: Eight databases were utilized for selecting eligible studies that were published from inception to Jan., 2020. The eligible studies were screened, extracted and then the methodological quality was evaluated independently by two researchers. RevMan version 5.3 software and Stata version 14.0 software were utilized for the meta-analysis. RESULTS: Seventeen studies were included in the meta-analysis. Compared with the control group, peer support significantly improved self-efficacy [SMD = 0.41, 95 % CI = (0.20, 0.62), p = 0.0001] and self-management [SMD = 1.21, 95 % CI = (0.58, 1.84), p = 0.0002] in people with type 2 diabetes, but had no significant effect on distress (p = 0.34). CONCLUSIONS: Peer support significantly improved self-efficacy and self-management, but there was no clear evidence that peer support improved distress in people with type 2 diabetes. More studies are needed to further verify the validity of the results. PRACTICE IMPLICATIONS: This meta-analysis suggested that peer support should be considered as a complementary treatment for patients with type 2 diabetes. Medical staff can encourage the use of peer support in the teaching content of patients with type 2 diabetes to improve their self-efficacy and self-management.

The effectiveness of adjunct music therapy for patients with schizophrenia: A meta-analysis.

To evaluate the efficacy of adjunct music therapy on patients with schizophrenia, we conducted a meta-analysis of currently available randomized controlled trials and controlled clinical trials. Eight electronic databases (CNKI, PubMed, EMBASE, Cochrane Library, PsycINFO, Web of Science, Psychology and behavioural Sciences Collection, and Medline) were systematically searched from inception to January 2020. Standard mean difference (SMD) with 95% confidence interval (CI) values were used to evaluate the effects of music therapy. Finally, we selected eighteen studies comprising 1,212 participants comparing with control conditions. The meta-analysis demonstrated that adjunct music therapy significantly improved total symptoms (SMD = -0.48, 95%CI: -0.74 to -0.22), negative symptoms (SMD=-0.56, 95%CI: -0.72 to -0.40), depression symptoms (SMD = -0.35, 95% CI: -0.54 to -0.17), and quality of life (SMD = 0.35, 95%CI: 0.07 to 0.62) in people with schizophrenia compared with the control group. In addition, the meta-analysis indicated no publication bias for total symptoms, negative symptoms, and positive symptoms. The sensitivity analysis showed that the result was reliable. But the quality of evidence is still low, more well-designed studies with larger sample size and high quality are needed to confirm the efficiency of adjunct music therapy in treating schizophrenia.

The effects of superchilling with modified atmosphere packaging on the physicochemical properties and shelf life of swimming crab.

The objective of the present study was to investigate the effects of superchilling with modified atmosphere packaging on the physicochemical properties and shelf life of swimming crab. As the storage time increased, the rates at which the total aerobic plate count, total volatile basic nitrogen, pH, peroxide value and thiobarbituric acid-reactive substances value increase were significantly lower for the superchilling with modified atmosphere packaging (SCS + MAP) treatment compared to superchilling storage (SCS) and chilling storage (CS). With increasing storage time, the carbonyl content of the proteins increased from 1.21 nmol/mg of protein (0 day) to 2.03, 1.87, 1.66 nmol carbonyl/mg protein on the 6th day for CS, SCS and SCS + MAP, respectively. The disulfide bonds increased in a similar manner, and the total sulfhydryl content, salt extractable protein and Ca-ATPase stability decreased. Sodium dodecyl sulphate polyacrylamide gel elcetrophoresis (SDS-PAGE) and microstructure analysis also indicated that SCS + MAP could reduce the degree of protein degradation. These results suggested that superchilling with modified atmosphere packaging offers an effective approach to slowdown protein and lipid oxidation, and extends the shelf life of swimming crab. However, superchilling with high-CO2 packaging had a negative effect on the surface hydrophobicity and drip loss of swimming crab.
