Abstract

Background: Negative symptoms represent the main cause of disability in schizophrenia, having recently been grouped into two general dimensions: avolition and diminished emotional expression, which includes affective flattening and alogia. The aim of this study was to explore the response of these two symptoms to a set of behavioral interventions based on contingency management, performed in an interdisciplinary context. Method: Behaviors of interest were monitored and evaluations before and after the treatment were performed on 9 schizophrenic inpatients with persistent negative symptoms. The program included 12 group double sessions aimed at developing facial expression and verbal communication, and a nursing care plan to generalize and strengthen these behaviors synergistically. Results: there were appreciable differences in facial expression, which were less clear for alogia. The clinical evaluation using PANSS-N did not find notable differences at group level, but the nursing assessment using NOC indicators did. Conclusions: although difficult to modify, negative symptoms are not insensitive to the influence of behavioral interventions. Specific psychological interventions that address negative symptoms as a priority focus of attention and care need to be promoted and developed, particularly when considering the crucial role of context in their progression.

Antecedentes: los síntomas negativos representan la principal causa de discapacidad en la esquizofrenia, habiendo sido agrupados recientemente en dos dimensiones: avolición y expresión emocional disminuida, que incluye el aplanamiento afectivo y la alogia. El objetivo del estudio fue explorar la respuesta de estos dos síntomas a un conjunto de intervenciones conductuales basadas en el manejo de contingencias en un contexto interdisciplinario. Método: se monitorizaron conductas de interés y realizaron medidas pre y post a 9 participantes con esquizofrenia negativa persistente ingresados en dispositivos de rehabilitación. El programa incluyó 12 sesiones grupales dobles dirigidas a trabajar la expresión facial y la comunicación verbal, y un plan de cuidados para fortalecer y generalizar estas conductas. Resultados: se obtuvieron diferencias relevantes en la expresión facial, que fueron menos claras para la alogia. La evaluación clínica mediante la PANSS-N no obtuvo diferencias notables a nivel de grupo, pero sí la valoración mediante indicadores NOC. Conclusiones: aunque difíciles de modificar, los síntomas negativos no son insensibles a la influencia de intervenciones conductuales. Resulta necesario potenciar intervenciones psicológicas específicas que aborden estos síntomas como un foco prioritario de atención y cuidado, considerando el papel crucial del contexto en su evolución.
