“…The relationship between negative life events and depression, loneliness, hopelessness, quality of life, family function and social support has been tested. Therefore, we used GDS, USL‐6, BHS, QOL, APGAR and the Duke Social Support Scale to assess the concurrent validity of LESE, which has a high degree of reliability and validity in the Chinese context . Both the intensity and the number of life events were all statistically correlated to GDS, ULS‐6, BHS, QOL and APGAR, showing that LESE had good convergent validity and discriminant validity.…”

Aim: The present study aimed to evaluate the validity of proxy informants' reports on Life Event Scale for the Elderly (LESE) by using psychological autopsy method among rural older adults in China.Methods: A multistage stratified cluster sampling method was used to select research sites. Using a case-control psychological autopsy study, face-to-face interviews were carried out to collect information from 242 suicide cases and 242 living controls. We compared the intensity and number of life events to assess the validity and reliability of LESE with proxy data reported by different informants. Data from proxy respondents of the living controls were compared with data reported by the targets (gold standards). Intraclass correlation coefficients were computed to evaluate the consistency of informants. Spearman's correlation analysis was used to analyze the convergent validity and discriminate validity of the LESE.Results: The number of life events between different informants showed higher intraclass correlation coefficients values than the intensity of life events, but the results of correlation analysis was similar. The LESE was positively correlated with depression, loneliness and hopelessness, and negatively correlated with quality of life, family function and social support both in suicide cases and living controls. Conclusions:The LESE has good convergent validity and discriminant validity. LESE is a valid instrument for measuring life events in psychological autopsy studies. We suggest using the number of life events to assess the validity and reliability with proxy data in a psychological autopsy study, which is more reliable than using the intensity of life events.

Background: Although late-life suicide in rural China is a matter of concern, research is scarce addressing the association between capability of daily living activities, family function, and late-life suicide. We conducted this psychological autopsy study to explore associations between disability in daily living activities, family dysfunction, and late-life suicide in rural China.Methods: Using a 1:1 matched case–control design, we collected data from 242 elderly suicide cases and 242 living community controls in rural China using the psychological autopsy method. We used Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (SCID), Activities of Daily Living Scale (ADL), and Family Adaptive, Partnership, Growth, Affection and Resolve scale (APGAR) to assess the presence of mental disorders, capability of daily living activities, and family function, respectively.Results: Compared with the living controls, suicide cases presented more severe impairment in capability of daily living activities and poorer family function. After controlling for all other factors, capability of daily living activities and family function remained in the final model. The results of the multivariate analysis also show that the presence of a mental disorder, lower levels of social support, and increased number of life events in the last year were significantly associated with elevated suicide risk.Conclusions: Disability in daily living activities and family dysfunction are associated with elevated risk of late-life suicide in rural China. It is warranted to design programs, including family interventions, peer-support groups, and community programs, to help the rural elderly improve activities of daily living and obtain the social support they need to prevent suicidal behaviors.

“…Good internal reliability and construct validity has been demonstrated for the 4-item SIS (Cronbach's alpha=0.80) and the 7item SSS (Cronbach's alpha=0.80) (Powers et al, 2004). The 23-item DSSI has shown good validity among both younger and older community-dwelling adults in China, with the subscales demonstrating good reliability, construct validity and internal consistency (Cronbach's alpha ≥0.88; Pan et al, 2018) in evaluating social support (Jia & Zhang, 2012;Pan et al, 2018).…”

“…High overall social support has been shown to have both direct and indirect positive effects on mental and physical health outcomes. Direct effects link increased social support with reduced depression, suicidal thoughts and time to mortality; whereas indirect effects may act by reducing depression or stress which in turn positively impacts quality of life, mood and suicidality (Holt-Lunstad et al, 2010;Pan et al, 2018;Sahin et al, 2019). Research has shown that as individuals reach later life, social support reduces and has a significant negative impact on mood and suicidality (Hybels et al, 2011;Pan et al, 2018).…”

Given that difficulties in social communication and interactions are a core diagnostic feature of autism spectrum disorder (ASD), it has been questioned whether the impact of variable levels of social support is the same for autistic versus non-autistic individuals.…”

Social support has a positive impact on quality of life (QoL) in neurotypical older adults and young autistic adults, but the association for older autistic adults is unclear. Autistic adults (n=388; mean age=40-83 years) were recruited via Simons Powering Autism Research for Knowledge research match. Participants completed questionnaires online querying demographic information, depression and anxiety symptomatology, QoL (Physical, Psychological, Social, Environmental, Autism-specific) and social support (instrumental, subjective and social interactions). Regression analyses examined whether different aspects of social support explained the variance in each domain of QoL. A significant proportion of the variance (36-58%) in QoL was explained. Subjective social support significantly contributed to the models for all aspects of QoL; Physical and Psychological QoL were also explained by social interactions, whereas Social, Environmental and Autism-specific QoL were additionally explained by instrumental support. Social support is an important contributor to the QoL of middle-aged and older autistic adults, after accounting for demographic factors and depression. Further studies are required to understand whether age-related changes in social support and QoL are the same for autistic as non-autistic older adults in order to identify and implement appropriate support.
