The Effect of Familism Emotions on Post-Traumatic Growth Among the Elderly in China: The Mediating Roles of Taoist Personality and Sense of Community

Purpose

Post-traumatic growth is a significant social issue in the management of active aging in elderly people. This study investigates the influence of familism emotions on post-traumatic growth (PTG) of the elderly, and the mediating role of Taoist personality and sense of community (SOC) therein, to provide a scientific basis for the development of positive aging in the elderly.

Methods

A cross-sectional study was conducted in several communities of Hubei Province in China. A total of 338 elderly people were investigated with the Familism Emotion Scale, PTG Scale, Taoist Personality Scale and SOC Scale. SPSS 23.0 was used to derive descriptive statistics and conduct a common method bias test, Pearson correlation analysis, and multiple stepwise regression analysis. Mplus 7.3 was used for structural equation modeling to test the significance of parallel mediation effects on the data.

Results

The results show that: (1) Familism emotions, Taoist personality and SOC are positively correlated with PTG; (2) Familism emotions, Taoist personality and SOC can all positively predict PTG in the elderly; (3) Both Taoist personality and SOC partially mediated the link between familism emotions and PTG in the elderly.

Conclusion

In the context of particularly constraining societal events such as COVID-19, it is necessary to pay careful attention to the impact of external environmental influences upon the elderly, such as family and community, and to encourage elderly people to cultivate a more Taoist personality. The formation of a Taoist personality offers a promising new focus for research in elderly healthcare.

Parental characteristics and offspring mental health and related outcomes: a systematic review of genetically informative literature

Various parental characteristics, including psychiatric disorders and parenting behaviours, are associated with offspring mental health and related outcomes in observational studies. The application of genetically informative designs is crucial to disentangle the role of genetic and environmental factors (as well as gene-environment correlation) underlying these observations, as parents provide not only the rearing environment but also transmit 50% of their genes to their offspring. This article first provides an overview of behavioural genetics, matched-pair, and molecular genetics designs that can be applied to investigate parent-offspring associations, whilst modelling or accounting for genetic effects. We then present a systematic literature review of genetically informative studies investigating associations between parental characteristics and offspring mental health and related outcomes, published since 2014. The reviewed studies provide reliable evidence of genetic transmission of depression, criminal behaviour, educational attainment, and substance use. These results highlight that studies that do not use genetically informative designs are likely to misinterpret the mechanisms underlying these parent-offspring associations. After accounting for genetic effects, several parental characteristics, including parental psychiatric traits and parenting behaviours, were associated with offspring internalising problems, externalising problems, educational attainment, substance use, and personality through environmental pathways. Overall, genetically informative designs to study intergenerational transmission prove valuable for the understanding of individual differences in offspring mental health and related outcomes, and mechanisms of transmission within families.
