Analysis

The analysis of the SSUS includes the evaluation of the psychometric reliability and validity of the tool. The internal consistency of the questions is usually examined using Cronbach’s alpha coefficient to ensure the coherence of responses. In addition, test–retest reliability is assessed through measurements at different points in time to determine the stability of responses. The validity of the tool is examined through comparative studies with other established measures of social support and through factor analyses to confirm the structure of the questionnaire.

Objective

The objective of the SSUS is to provide a reliable and valid instrument for assessing social support. This tool is particularly useful in research aimed at understanding the impact of social support on mental and physical health. It is also used in clinical practice for the rapid assessment of individuals’ support needs and for the development of interventions targeting the improvement of social interaction and well-being.

Scoring

The scoring of the SSUS is conducted using a Likert scale, where responses range from 1 (never) to 5 (always), depending on the frequency and intensity of the support individuals receive. Total scores are calculated by summing the scores of the individual questions for each dimension of support. Higher scores indicate greater perceived support.

References

The bibliography for the SSUS includes important studies that document the development and validation of the tool. One of the foundational studies is that of Sarason, Sarason, Shearin, and Pierce (1987), published in the Journal of Social and Personal Relationships. This study provides a detailed description of the development of the SSUS, the assessment of its reliability and validity, and its use in various populations and settings. Furthermore, studies such as that of Cohen and Wills (1985) examine the relationship between social support and psychological well-being, supporting the utility of the SSUS in research and clinical practice.
