Evidencia de la Validez y Fiabilidad de la Versión en Español de la Etapa de Recuperación Autoidentificada

Background: The Self-Identified Stage of Recovery (SISR) (Andresen, 2007) is a scale used to assess both the stage of recovery (SISR-A) and the components of the process of personal recovery (SISR-B). This study aimed to develop the Spanish version of the SISR and obtain evidence of validity and reliability in a sample of 230 users of community mental health services. Method: The Spanish version of the SISR was developed following the translation–back translation procedure, with the support of a committee of experienced experts. The SISR was examined in terms of dimensional structure, internal consistency, relationships with other variables (i.e., the Maryland Recovery Assessment Scale [MARS-12] and the Dispositional Hope Scale [DHS]), and temporal stability (n = 66). Differential item functioning (DIF) by gender was analysed. Results: The study confirmed the unidimensionality of the SISR-B and suitable internal consistency of its scores (ω = .83, α = .83). Scores from both SISR-A and SISR-B showed good temporal stability and the SISR-B displayed strong correlations with the MARS-12 (rs = .78) and the DHS (rs = .67). No DIF was found. Conclusions: This study supports the validity and reliability of the scores of the Spanish version of the SISR.
