Appreciation in Relationships (AIR) Scale: Preliminary Evidence of Validity and Accuracy in Brazil

Abstract This study aimed to adapt the Appreciation in Relationships (AIR) scale for the Brazilian context and to seek evidence of validity and accuracy, based on evidence of construct validity (i.e. factor analysis and internal consistency). The sample consisted of 233 people in amorous relationships from 15 Brazilian states, over 18 years of age. The majority were women (52.4%), even though a population with a homogeneous composition was sought to respond to the instruments: AIR and Sociodemographic Questionnaire. Through Structural Equation Modeling, with Confirmatory Factor Analysis, the theory regarding the existence of two factors was confirmed. The two-factor model presented the following fit indices: χ2 / df = 2.70, CFI = 0.97, TLI = 0.96, RMSEA (90%CI) = 0.08 (0.07-0.10). It was concluded that the AIR presents acceptable evidence regarding the psychometric parameters in the context, and can be used in further studies on appreciation in relationships
