RESUMO
El Modelo Bifactorial de Afectividad de Watson y Tellengen se ha postulado para la diferenciación de la ansiedad y la depresión en Europa y Norteamérica, pero no se han reportado estudios en población cubana de edad media. El objetivo de esta investigación fue investigar la Afectividad Positiva (AP) y la Afectividad Negativa (AN) en personas sin psicopatología, con sintomatología predominantemente ansiosa, depresiva o mixta. La muestra fue de 219 personas; 19,2% con sintomatología ansiosa, 17,8% depresiva, 23,7% mixta y el resto sin síntomas. Se utilizó el Inventario de Afecto Positivo y Negativo (PANAS) para estudiar la afectividad y la Escala de Ansiedad y Depresión de Goldberg (EADG) para diferenciar los subgrupos diagnósticos. Se utilizó el ANOVA de un factor con el Método de la Diferencia Significativa Honesta de Tukey para establecer las diferencias. Se encontró que la AP era menor en los depresivos tal y como predice el Modelo, pero no se cumplió la predicción de que la AP diferenciaría a los ansiosos de las personas sin síntomas, y se encontró que en el grupo con sintomatología mixta había mayor AN y menor AP que en los otros subgrupos patológicos, lo cual alerta sobre la necesidad de evaluar los modelos desarrollados en otras culturas.
Two-Factor Model of Emotion of Watson and Tellengen has been investigated for the differentiation of anxiety and depression in Europe and North America, but no studies have been reported on middle-aged Cuban population. The objective of this research was to investigate the negative (NA) and positive affectivity (PA) in individuals without psychopathology, predominantly anxious, depressive or mixed symptoms. The sample was 219 subjects; 19.2% with symptoms of anxiety, 17.8% has depression, 23.7% mixed anxiety and depression symptoms, and the rest without symptoms. Positive and negative affect schedule (PANAS) was used to study emotion; and Anxiety and Depression Scale Goldberg (GADS) to differentiate diagnostic subgroups. The one-way ANOVA was used with the method of Tukey Honest Significant Difference. We found that AP was lower in depressive as predicted by the model, but the prediction that the AP would differentiate anxious people without symptoms was fulfilled, which highlights the need to evaluate the models developed in other cultures.
RESUMO
OBJECTIVES: Previous studies have suggested that some personality characteristics are associated with the onset, prognosis and social function in schizophrenia patients. However few is known about the personality and affective characteristic of genetic high risk group (GHR) for schizophrenia. This study aimed to investigate the personality and the affective characteristic of GHR group for schizophrenia. METHODS: Participants were 54 healthy controls (HC), 26 subjects with GHR for schizophrenia and 28 subjects with first episode psychosis (FEP). We performed three self-report questionnaires; NEO-Personality Inventory-Revised, State and Anger Expression Inventory and Positive Affect and Negative Affect Schedule. RESULTS: The GHR group showed higher score in agreeableness item than the HC (p=0.028). In extraversion item, the FEP group showed significantly lower scores than the HC (p=0.001). The GHR group showed lower scores in neuroticism item compared with FEP group in trend level. The FEP group showed higher trait-anger, lower positive affect and higher negative affect compared with the others. CONCLUSION: The GHR group seem to share certain vulnerable personality and affective characteristics for schizophrenia with the FEP group. On the other hands, the GHR group appeared to be more agreeable than the other groups, which might act as the compensation for other impaired functions.
