Validation of the abbreviated Lubben Social Network Scale (LSNS‐6) and its association with self‐rated health amongst older adults in Puerto Rico

Social isolation is a well‐established determinant of late‐life well‐being, and it may be particularly relevant for older adults in Puerto Rico following Hurricane María. The abbreviated Lubben Social Network Scale (LSNS‐6) is a widely used measure of social isolation, but it has not been validated with Spanish‐speaking older adults. The objectives of this study were to (1) assess the psychometric properties of a Spanish‐language LSNS‐6 and (2) examine its association with self‐rated health (SRH) and psychological sense of community (PSOC). Data came from face‐to‐face survey interviews with a nonprobability sample of 154 community‐dwelling older adults in Puerto Rico 2 years after Hurricane María. We assessed the LSNS‐6's internal consistency reliability and convergent validity. We then conducted structural equational modelling consisting of (1) a measurement model using confirmatory factor analysis to test the factor structure of the LSNS‐6 and (2) a structural model using path analysis to examine the direct effect of social isolation on SRH and to test the role of PSOC as a mediator in this relationship. The LSNS‐6 demonstrated acceptable internal consistency reliability (α = 0.74) and convergent validity, r(151) = −0.33, p
