Spanish version of the Link's Perceived Devaluation and Discrimination scale.

BACKGROUND: The aim of this study is to translate, adapt and validate the “Perceived Devaluation and Discrimination Scale” (PDD) in Spanish in a sample of people with schizophrenia. METHOD: A total of 130 people between 18 and 65 years and with a diagnosis of schizophrenia according to DSM-IV-R criteria from Barcelona and Vitoria were included. The patients were assessed with the translated version of the PDD, the Social Functioning Scale (SFS), the Global Assessment of Functioning (GAF), the Clinical Global Impression Scale (CGI-S) and the Self-perception of Stigma Questionnaire for people with schizophrenia (SSQ). RESULTS: The questionnaire scored a Cronbach’s a of .868 regarding its internal consistency reliability. Two components were found in the factorial analysis explaining 40% of the variance of the instrument (component 1 associated with individual self-perception and component 2 refers more to social stigma). The stability of the instrument   measured using the intraclass correlation coefficient on both occasions oscillated between .415 and .806. Significant correlations were found with SSQ and SFS. CONCLUSIONS: The Spanish version of the PDD seems a good instrument for the assessment of self stigma.

Validación de la versión española del inventario de asertividad Gambrill y Richey en población con diagnóstico de esquizofrenia / Validation of the Spanish version of the inventory of Gambrill and Richey assertiveness in people diagnosed with schizophrenia

Objetivo: Validar la versión española del Cuestionario de Asertividad de Gambrill y Richey en personas con esquizofrenia. Método: La muestra está compuesta por 125 personas con esquizofrenia en tratamiento en uno de los centros de rehabilitación psicosocial que participan en el estudio. Los instrumentos utilizados para valorar la validez discriminante y convergente son: el cuestionario de habilidades de comunicación(CSQ); la Escala de Funcionamiento Social(EFS); el Perfil de Habilidades de la Vida Cotidiana(LSP);la Escala de Impresión Clínica Global (ICG) y la Escala de Funcionamiento Global(GAF). Resultados: La consistencia interna del instrumento muestra un alfa de Cronbach de .935 en la escala total. Los coeficientes de correlación intraclase para valorar la consistencia temporal del instrumento oscilan entre .21 y .78. El instrumento muestra validez convergente con la escala CSQ y con las subescalas de comunicación y aislamiento social (p < .001-.05). Con el resto de subescalas de funcionamiento social muestra validez divergente. Con la CGI muestra validez divergente con la probabilidad de respuesta, sin embargo encontramos que hay validez convergente entre las subescalas de CGI y la subescala de grado de malestar del instrumento (p < .012-.042). Conclusiones: El instrumento muestra unas buenas características psicométricas y parece útil para la valoración de las habilidades sociales en una muestra de personas con esquizofrenia

Objective: To validate the Spanish version of the questionnaire Gambrill and Richey Assertiveness for people with schizophrenia. Method: he sample comprised a total of 125 people with schizophrenia on treatment in one of the psychosocial rehabilitation centers participating in the study. The instruments used to assess convergent and discriminant validity are the Communication Skills Questionnaire (CSQ); the Social Functioning Scale(SFS); the Life Skills Profile(LSP); the Clinical Global Impression Scale(CGI) and the Global Functioning Scale (GAF). Results: Internal consistency of the instrument shows a Cronbach alpha of .935 in the full scale. The intraclass correlation coefficients to assess the instrument's internal consistency ranged between .21 and .78. The instrument shows a convergent validity with CSQ scale and the subscales of communication and social isolation (p < .001-.05). With the rest of social functioning sub-scales shows divergent validity. With the CGI shows divergent validity with the probability of response, and convergent validity between the subscales of CGI and the degree of distress subscale of the instrument (p < .012-.042). Conclusions: The instrument shows good psychometric characteristics and appears useful for assessing social skills in a sample of people with schizophrenia
