Validation of an abbreviated version of the Lubben Social Network Scale (“LSNS-6”) and its associations wiht suicidality among older adults in China.

Objective
This present study aims to estimate the structural validity, internal consistency reliability of
the LSNS-6 and examine the associations between the LSNS-6 and suicidal outcomes
among mainland Chinese older adults.
Methods
This validation study used a big representative sample (N = 2819) of older adults in Beijing
from the Sample Survey on Aged Population in Urban/Rural China. Confirmatory factor
analyses (CFA) were applied to examine the factor structures of the Chinese version of
LSNS-6. Internal consistency reliability of the LSNS-6 was examined by Cronbach’s alpha
coefficient and the corrected item-total correlation. Logistic regression analyses were used
to explore the associations between the LSNS-6 and late-life death wishes, suicidal ideation
in mainland Chinese.
Findings
This present study showed good internal consistency and consistent factor structure of the
LSNS-6 as well as its subscales. The present data demonstrated the LSNS-6 could be a
useful tool for assessing social networks among older mainland Chinese. Interestingly,
among the mainland Chinese, late-life suicidality was highly associated with the LSNS-6
family subscale, rather than the friends subscale.
Conclusion
The LSNS-6 could be a useful tool for assessing social networks among older mainland Chinese.
In addition, suggestion is made to improve social networks, especially in family bonds
and support, as a promising strategy in reducing late-life suicide risks in mainland China.
