Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicología del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Background: There is little research on self-reported negative symptomatology measures in schizophrenia. The aims of this study were to validate the Spanish version of the Motivation and Pleasure Scale-Self-Report (MAP-SR) and determine the concordance between patient-reported outcome measures for reflecting the severity of negative symptoms of schizophrenia and clinician-rated outcome measures. Method: A sample of 174 subjects who completed the MAP-SR and 104 who completed the Self-Evaluation of Negative Symptoms (SNS) were analyzed. The clinician-reported outcome measures (CROMs) were the Spanish versions of the Clinical Assessment Interview for Negative Symptoms (CAINS) and the Positive and Negative Syndrome Scale (PANSS), while the patient-reported outcome measures (PROMs) were MAP-SR and SNS. Cronbach’s a, bivariate analyses and Lin’s concordance correlation coefficient (CCC) were calculated. Results: The Spanish version of the MAP-SR demonstrated excellent reliability (Cronbach’s α=.923). Its correlation coefficients were higher with CAINS [CAINS-Total: r=.608, p<.005; CAINS-Motivation and Pleasure subscale(CAINS-MAP): r=.662, p<.005] than with PANSS negative scales [PANSS-Negative scale(PANSS-N): r=.393, p<.005; PANSS-Marder Negative Factor(PANSS-MNF): r=.478, p<.005]. Finally, concordance between clinician and patient ratings was low in all cases, varying from a CCC of 0.661 to .392. Conclusions: We found poor concordance between patient and clinician ratings, hence we believe that the two evaluations are not mutually exclusive but complementary.
Validación Española de la MAP-SR: Dos Perspectivas Mejor que Una en la Evaluación de los Síntomas Negativos de la Esquizofrenia. Antecedentes: existe poca investigación sobre autoinformes de evaluación de la sintomatología negativa en esquizofrenia. Los objetivos de este estudio son validar la versión española de la Escala-Autoinforme de Motivación y Placer (MAP-SR) y determinar la concordancia entre pruebas autoaplicadas y heteroaplicadas para los síntomas negativos de la esquizofrenia. Método: se analizaron los datos de una muestra de 174 personas que completaron la MAP-SR y 104 que completaron la Autoevaluación de los Síntomas Negativos (SNS). Mientras que como pruebas heteroaplicadas se aplicaron las versiones en español de la Entrevista Clínica de Evaluación de Síntomas Negativos (CAINS) y la Escala del Síndrome Positivo y Negativo de la Esquizofrenia (PANSS), como autoinformes se aplicaron la MAP-SR y SNS. Resultados: la versión en español de la MAP-SR ha mostrado excelente fiabilidad (α de Cronbach’s=.923. Sus coeficientes de correlación han sido mayores con la CAINS [CAINS-Total: r=.608, p<.005; CAINS-subescala de Motivación y Placer (CAINS-MAP): r=.662, p<.005] que con las escalas negativas de la PANSS [PANSS-escala Negativa (PANSS-N): r=.393, p<.005; PANSS-Factor Negativo de Marder (PANSS-MNF): r=.478, p<.005]. La concordancia entre clínicos y pacientes fue baja en todos los casos, variando de un CCC de .661 a .392. Conclusiones: observamos pobre concordancia entre las puntuaciones de los pacientes y los clínicos, por lo que creemos que las evaluaciones de ambos no son mutuamente excluyentes, sino complementarias.
