Psychometric Adaptation of the Sense of Community Index (SCI-II) in Chilean public schools

This study aimed to adapt the Sense of Community Index (SCI-II) in Chilean schools and to examine its psychometric properties. The validation process was conducted with 2871 students from 6th grade of elementary school to 4th grade of high school in a city of Northern Chile. A 52.4 % (n = 1506) of the sample identified with the female gender and the average age of the sample was 14.64 (SD = 2.046). An exploratory factor analysis indicated a three-factor solution: school connectivity, valued belongingness, and membership-reciprocity. The reliability of the scale was adequate (α = .879 for school connectivity, α = .884 for valued belongingness and α = .716 for membership-reciprocity), and confirmatory analyzes indicated adequate adjustment rates (CFI = .939; TLI = .933). It was concluded that the proposed model of the adapted version is valid and is appropriate to be used in future studies on the sense of community in the school context. Finally, the article discusses the value of this instrument for public policies and innovation processes of public education.
