RT Journal Article T1 Factor Analysis of EMA-Scale on Adolescent Adjustment From a Developmental Perspective: A Short Form A1 Jiménez, Lucía A1 Menéndez Álvarez-Dardet, Susana A1 Hidalgo García, María Victoria AB Many published instruments for assessing adolescent adjustment can be implementedin the school context. However, most of them fail to include a comprehensive andpositive theoretical perspective of adolescent development and, even when theydo, priority is often given to the clinical perspective, or problems with ecologicalvalidity and cost-effectiveness emerge. The Magallanes Adaptation Scale is a 90-itemLikert-instrument designed for Spanish-speaking adolescents in order to screen severaladjustment areas froma holistic and positive perspective of development. Although someevidence of its psychometric robustness has been tested, no confirmatory analysis of itsstructure has been published. This paper analyzes the items and the factor structure(exploratory factor analysis and confirmatory factor analysis, using the split-half method)of the scales. Participants were 948 Spanish adolescents (49.84% girls) aged between11 and 17 and stratified sampled. Thirty-six items were removed from the item analysis.The results of the exploratory factor analysis revealed five factors, excluding mother’sadaptation. Several models were tested during the confirmatory factor analyses, witha 24-item second-order four-factor solution being found to have the best adjustmentindicators. The short version proposed in this paper can constitute a helpful tool withscreening purposes to help school teachers to assess students’ overall developmentbeyond mere academic performance, although further validity research is needed.
