[Spanish adaptation of the Scale to Asses Unawareness of Mental Disorder (SUMD)]. / Adaptación al español de la escala de valoración de la no conciencia de trastorno mental (SUMD).

INTRODUCTION: The aim of this paper is to examine the reliability and external validity of the Spanish adaptation of the Scale to Assess Unawareness of Mental Disorder (SUMD). METHOD: A translation-backtranslation of the original scale was elaborated, and a panel of professionals participated to assess conceptual equivalence and naturality. The scale consists of 3 general items: awareness of mental disorder, awareness of the effects of medication and awareness of the social consequences of the disorder; and of 17 items related to specific symptoms, which make up two subscales: awareness and attribution. Thirty-two patients diagnosed of schizophrenic or schizoaffective disorder following DSM-IV criteria were evaluated. The evaluations were performed using interviews with an observer. Intraclass Correlation Coefficient (ICC) was calculated for the reliability analysis and the Spearman correlation coefficient between the SUMD scores and one independent score of global insight for external validity. RESULTS: The ICC were all over 0.70. Convergent validity with the independent global measurement of insight was found for the general items of awareness of mental disorder and awareness of the effects of medication, and for the subscale on awareness of symptoms. The awareness of the social consequences of the disorder and the subscale on attribution did not correlate significantly with the global measurement of awareness (insight). These results are consistent with the hypothesis that awareness (insight) is a multidimensional phenomenon. CONCLUSION: The Spanish adaptation of the SUMD scale is conceptually equivalent and displays a similar reliability and external validity as the original version.

Introducción. El objetivo del trabajo es examinar la fiabilidad y la validez externa de la versión en español de la Escala de valoración de la no conciencia de enfermedad mental (SUMD). Metodología. Se utilizó un método de traducción-retrotraducción y la participación de un panel de profesionales para valorar equivalencia conceptual y naturalidad. La escala se compone de 3 ítems generales: conciencia de trastorno mental, conciencia de los efectos de la medicación y conciencia de las consecuencias sociales del trastorno, y de 17 ítems destinados a síntomas específicos que conforman dos subescalas: conciencia y atribución. Se valoraron 32 pacientes con trastorno esquizofrénico o esquizoafectivo, según criterios DSM-IV. Las evaluaciones fueron realizadas mediante el sistema de entrevista con observador. Se calculó la fiabilidad a través del coeficiente de correlación intraclase (CCI) y la validez externa mediante el coeficiente de correlación de Spearman entre las puntuaciones de la escala y una medida independiente de conciencia global de trastorno. Resultados. El CCI fue siempre superior a 0,70. Los ítems generales conciencia de trastorno y conciencia de los efectos de la medicación y la subescala conciencia de los síntomas se correlacionaron significativamente con la medida global de conciencia. Contrariamente, el ítem general conciencia de las consecuencias sociales del trastorno y la subescala de atribución no se correlacionaron significativamente, lo que apoyaría la idea de que la conciencia de trastorno es un fenómeno multidimensional. Conclusiones. La versión al español de la escala SUMD es conceptualmente equivalente y presenta una fiabilidad y validez similares a la original (AU)
