摘要：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.
