Measuring Social Frailty: A Scoping Review of Available Scales and Tools

Social frailty is an emerging concept characterized by state of vulnerability due to the lack or absence of social resources that enable health and well-being, particularly among older people. However, there is no consensus on how to accurately measure and assess social frailty, given the broad coverage of social dimensions affecting older individuals. This scoping review aimed to identify the existing tools and scales used to measure social frailty in older people.

A scoping review methodology was employed. Articles published between January 2014 and April 2024 were searched in 6 electronic databases: PubMed, PsycINFO, ProQuest, Scopus, SocIndex, and CINAHL. The scoping review followed a 5-stage process by Arksey and O'Malley and adhered to the guidelines provided by Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews.

Nine social frailty tools were identified across the 58 papers included in this review. The individual question item commonly used in the scales were classified into main categories based on their conceptual characteristics and intentions. The most common individual questionnaire constructs used to measure social frailty included financial status, social resources, social behaviors and activities, and sense of purpose. The reviewed tools varied in terms of their robustness and the process of scale development.

Our review suggested the development of a standardized, psychometrically tested, and accurate screening tool to screen social frailty status. An accurate social frailty assessment can inform the development of useful interventions, which also has implications in preventing the development of physical frailty.
