TELLEZ ROJAS, Mario Arturo y RIVERA FONG, Liliana. Development and validation of an instrument to measure social exclusion perception in young people. Psicogente [online]. 2020, vol.23, n.43, pp.144-166. Epub 29-Dic-2019. ISSN 0124-0137. https://doi.org/10.17081/psico.23.43.3294.
Introduction:
Social exclusion is a multifactorial phenomenon that involves economic, institutional and social disadvantages for diverse groups of people. Frequently, young people face social exclusion that causes them negative consequences.
Objective:
To develop and validate an instrument to evaluate social exclusion perception in young people from Mexico.
Method:
This is an article research result, which is based on psychometric principles. During the first phase, a preliminary instrument version was developed on the base of a literature review. Experts and a group of young Mexican people evaluate items’ quality. During the second phase, 415 participants were enrolled and the instrument psychometric properties (reliability, validity, and interpretation) were estimated.
Results:
The first version instrument included 60 items which were evaluated in the second phase. The final version of the instrument has 35 items grouped in nine factors that explained 62,30 % of the total variance. This instrument's factorial structure showed high internal consistency (α=.863). The confirmatory factorial analysis indicated an acceptable fit (x2=1.71; CFI=.926; RMSEA=.042) which gave evidence of the instrument empirical validity.
Conclusion:
Instrument has good psychometric properties to evaluate social exclusion perception; therefore it can be used in the psychosocial investigation. Social exclusion phenomenon has been studied on base the politics, economic and sociology sciences; however until author knowledge, this is a pioneer proposal to study social exclusion based on the social psychology. This science is focused in the subject vision and their group social interactions.
