Analysis

The analysis of the SCI-2 involves scoring the responses given to the items of the tool. Each question is rated on a Likert scale, usually from 1 to 5, where 1 represents the lowest agreement or positive perception and 5 the highest. The responses are analyzed both overall and by dimension, allowing for an assessment of the overall sense of community as well as an understanding of strengths and weaknesses in each of the four dimensions. This analysis can be used for comparative studies between different communities or for evaluating the effectiveness of interventions aimed at improving the sense of community.

Purpose

The main purpose of the SCI-2 is to identify and quantify the sense of community within a group. This tool enables researchers, social scientists, and policymakers to better understand how individuals feel about their community and how these perceptions can influence their behavior, participation, and well-being. By collecting and analyzing data from the SCI-2, it is possible to identify areas that need improvement and to develop strategies to enhance the sense of community.

Calibration

The calibration of the SCI-2 includes the use of statistical techniques to ensure the reliability and validity of the measurement tool. This involves testing the internal consistency of the items (using indicators such as Cronbach’s Alpha) and confirming structural validity through factor analysis. Additionally, calibration may include comparative analyses with other measures of sense of community or related psychosocial constructs. Proper calibration ensures that the SCI-2 is a reliable and valid tool for assessing the sense of community across different contexts and populations.
