Social inclusion level of Spanish and foreign adolescents: Proposal for an evaluation instrument.

Unlabelled: Social exclusion is one of the most complex and sensitive social problems nowadays. Of all social groups, adolescents are among the most vulnerable to social exclusion, which can interfere with their social development. Consequently, the evaluation of this construct in adolescents is an important matter. The aim of this investigation was to develop the Social Inclusion for Adolescents Scale (SIAS). Firstly, five psychosocial factors were proposed, which potentially contribute to social inclusion: (1) covered needs, (2) self-efficacy, (3) social support, (4) job training, and (5) social integration. From these five factors, a set of items was created and reduced using qualitative evaluations. The final set of items was used in three studies, with a Spanish population ( = 1540) and a foreign population ( = 460), to test the psychometric properties of the scale, its dimensional structure, the measurement invariance between Spanish and foreign people, the reliability of the instrument and the evidence of the validity of its measurements. The results indicate that this scale is psychometrically reliable enough to assess social inclusion in adolescents.
