Lifestyle Behaviors and Depressive Symptoms in Chinese Adolescents Using Regression and fsQCA Models

Configurational effects of intergenerational support on older adults' depression: an empirical study from CHARLS data

BACKGROUND

The influence of different dimensions of intergenerational support on depression in older adults has a configuration effect. Existing researches have only used linear analyses to examine the independent effects of each dimension of intergenerational support on depression in older adults, resulting in the nature of the effects of each dimension of intergenerational support on the presence of depression in older adults remaining highly controversial.

OBJECTIVE

To explore the synergy and substitution effects (configurational effects) of dimensions of intergenerational support on depression in older adults.

METHOD

Based on data from the 2018 China Health and Retirement Longitudinal Study(CHARLS), depression among older adults was used as the outcome variable, and intergenerational support (including three dimensions of emotional, economic, and caregiving support) was used as the antecedent variable. Qualitative comparative analysis (QCA) was used to analyze the configurational effects of intergenerational support on depression in older adults.

RESULT

A single dimension of intergenerational support cannot be a necessary condition for depression in older adults.Factor configurations of different dimensions of intergenerational support as a sufficient condition for depression in older adults. The consistency parameter for all solution configurations in this study is 0.83, with a coverage of 0.61. The research identifies four types of configurational patterns associated with older adults' depression: "Unidirectional Care Deficiency Type" (consistency mean of 0.84, coverage of 0.49), "Bidirectional Care Deficiency Type" (consistency mean of 0.86, coverage of 0.33), "Bidirectional Economic Deficiency Type" (consistency mean of 0.85, coverage of 0.48), and "Mixed Type" (consistency mean of 0.83, coverage of 0.23).

CONCLUSION

Depression in older adults is influenced by the configurational effects of intergenerational support. The complex link between intergenerational support and depression in older adults should be examined from a holistic perspective, paying attention to the dynamic balance of intergenerational support reception and provision.

Associations between levels of physical literacy and adherence to the 24-h movement guidelines among university students: A cross-sectional study

Objectives

Emerging evidence indicates that the composition of movement behaviours within a 24-h period is associated with multiple health benefits across the lifespan. A concept that emphasises an individual's active lifestyle is physical literacy (PL), yet empirical research exploring the potential associations between PL and 24-h movement guidelines remains scarce. This study aimed to evaluate the associations between levels of PL and adherence to the guidelines among Chinese university students.

Study design

A cross-sectional study.

Methods

Seven hundred and ninety-eight university students (390 male, 19.2 ± 1.2 years) completed all the measurements. Levels of PL and participants' adherence to guidelines including physical activity, sedentary behaviour and sleep were self-reported through Perceived Physical Literacy Instrument, International Physical Activity Questionnaire and Pittsburgh Sleep Quality Index, respectively. Two-way ANOVA was conducted to determine the associations between the number of guidelines met (0, 1, 2, or 3) and levels of PL.

Results

The results demonstrate that 36.5% (n = 291) of the participants met all the three guidelines, while 4.1% (n = 33) met none. Further analysis indicated that meeting physical activity or sedentary behaviour guidelines was associated with significantly higher total PL scores, and scores in the sub-domains of Confidence and Physical Competence and Motivation.

Conclusions

The findings provide evidence that young adults who obtained higher PL scores may meet more guidelines during a 24-h period. Future studies should incorporate accelerometer-based physical activity measurements and investigate the causal relationship between PL and adherence to the movement guidelines.

The factors of job crafting in emergency nurses: regression models versus qualitative comparative analysis

BACKGROUND

Job crafting is defined as a series of proactive behaviors exhibited by employees in order to balance work resources and needs, which has a significant positive impact on the nurses. It is necessary to find the core factors that influence the job crafting, as emergency nurses deal with the most complex tasks, so as to improve their job satisfaction.

OBJECTIVES

To investigate the core factors of job crafting among emergency nurses.

METHODS

A cross-sectional design was used in the study. A total of 255 nurses were recruited from two hospitals in Zhengzhou and Shenzhen, China in December 2021. 255 nurses completed an online questionnaire. Hierarchical regression models and fsQCA models were used to explore the factors influencing job crafting among emergency nurses and helped us to identify core factors.

RESULTS

The hierarchical regression model and the fsQCA model found that the occupational benefit, psychological empowerment, and research experience were the core factors affecting their job crafting. Job involvement was not significant in the regression model, but the QCA model indicated that it needs to be combined with other factors to impact on job crafting. The QCA model uncovered seven key conditional configurations that led to high and low job crafting among emergency nurses, explaining 80.0% of the results for high job crafting and 82.6% of the results for the low job crafting, respectively.

CONCLUSIONS

The results of this study provide valuable insights into the job crafting experienced by emergency nurses. Junior emergency nurses should be granted a high level of psychological empowerment without assigning them overly complex tasks, such as research tasks, as these challenges can stop their job crafting. Intermediate and senior emergency nurses, on the other hand, can be assigned research tasks coupled with high psychological empowerment to enhance their job crafting.
