The Security in the Interparental Subsystem Scale: Evidence of Validity in Brazil




emotional regulation, adolescents, adaptation, psychometrics


emotional regulation in adolescents is an aspect little observed, especially by researchers and health professionals in Brazil. This study aimed to translate, adapt and examine the psychometric properties, internal consistency and construct validity of The Security in the Interparental Subsystem Scale (SIS) in a sample of 345 adolescents aged 14 to 18 years (M = 16.06 years, SD = 1.22). The results, obtained by Structural Equation Modeling, showed a six-factor version, namely: emotional reactivity, behavioral dysregulation, avoidance, involvement, destructive representations of the family, and representations of conflict overflow. The models showed good adjustment with invariance between the analyzed groups. The reliability of the scale showed adequate values. The tests performed suggest that the SIS presents satisfactory psychometric properties in the population of adolescents in the sample, therefore, a reliable measuring instrument for use in Brazil by clinicians and researchers.
