Interiorización y exteriorización han sido estudiados como tendencias o rasgos de la personalidad, próximos a los conceptos de neuroticismo y extraversión, relacionados con la estructura bifactorial del afecto y con el estilo de afrontamiento. Este trabajo examina su interacción en personas con trastorno de personalidad (n= 358). El afecto negativo (AN) es superior en los interiorizadores que en los exteriorizadores (g= 0,62); también la gravedad sintomatológica (GSI: g= 0,60). Los análisis de mediación muestran que el efecto del tipo de personalidad sobre el GSI está mediado parcialmente por la disposición afectiva y por el estilo de afrontamiento. El 88,1% de la muestra presenta un estilo de afrontamiento desfavorable y su frecuencia es mayor entre los interiorizadores (93% vs 83%; 2= 7,23; p= 0,007). Pero el subgrupo de interiorizadores con estilo de afrontamiento favorable (EAF) no se diferencia de los exteriorizadores con EAF en AN (p= 0,428) ni en GSI (p= 0,082). Independientemente de la estructura de la personalidad, el aprendizaje de estrategias favorables y adaptativas puede mejorar el estado psicopatológico de pacientes graves.
Diversos abordajes terapéuticos para personas con trastorno de personalidad (TP) postulan diferentes mecanismos de cambio. Investigamos si el constructo fusión cognitiva (FC) es relevante en el cambio terapéutico detectado en un grupo de personas diagnosticadas de TP grave (N = 110) tras 6 meses de intervención hospitalaria. Su nivel de FC es superior al de otras muestras publicadas (M = 38.5, DT = 8.98) y se asocia a mayor patología. Está relacionado con otros constructos como pensamientos automáticos (r = .529; p < .01) y actitudes disfuncionales (r = .368, p < .01). La FC se reduce tras el tratamiento (t = 4.897, p = .000, d = 0.65), pero no se confirma el supuesto del efecto obstaculizador de la FC sobre el cambio sintomático en la depresión, la perturbación global o la gravedad del TP. Se discuten los hallazgos en el contexto del solapamiento de variables como posible explicación de la constatación de que diferentes terapias produzcan beneficios similares y como acicate para seguir construyendo una práctica terapéutica basada en la evidencia.
The usual emotional experience of the person (affective style) is an influential factor in therapeutic assimilation. Based on a dynamic model of affect shaped dimensionally by the valence and arousal axes (core affect) that fluctuate over time according to the specific context of the individual, its relationship with different variables was investigated and the changes after a 6-month intervention in a specialized hospital unit (N = 103) were observed. The orthogonal structure of core-affect was confirmed. Emotional valence appeared to be positively related to social skills (r = .375; p < .01) and self-esteem (r = .491; p < .01) and negatively to depressive symptoms (r = -.631; p < .01), general disturbance (r = -.395; p < .01) and suicidality (r = -.490; p < .01). Emotional arousal is associated with impulsivity (r = .345; p < .01). The group of patients with an affective style characterized by negative valence and low arousal core-affect gained less therapeutic benefit compared to those with positive valence core-affect (p < .05). Throughout the treatment, valence became more positive (d = .26; IC 95%: 1.9 - 7.2; p = .001), arousal increased (d = .23; IC 95%: 0.2 - 1.7; p = .015) and variability decreased (d = -.44; IC 95%: (-2.9) - (-1.1); p = .001). Changes in the core-affect are related to therapeutic improvement. Adjusting expectations of change can reduce therapeutic frustration, which is as common as it is harmful in the treatment of severe personality disorders.
The concepts of internalization and externalization have been proposed as personality tendencies or traits related to the constructs of neuroticism and extraversion. They have been associated to the bifactorial structure of affect and also to the coping style. This paper examines the interaction of personality, affect and coping in a sample of people diagnosed with personality disorder (n= 358). Negative affect (NA) in internalizers is higher than in externalizers (g= 0.62), and so is the severity of symptoms (GSI: g= 0.60). Mediation analyses show that personality type produces an indirect effect on GSI, with NA and coping style as partial mediators. 88.1 % of the sample has an unfavourable coping style (U-CS). The frequency of U-CS among internalizers is bigger than among externalizers (93% vs 83%; 2= 7.23, p= .007). However, the subgroup of internalizers with a favourable coping style (F-CS) shows no difference with externalizers with the same F-CS, either in NA (p= .428) or in GSI (p= .082). Regardless of personality structure, promoting adaptive strategies of coping can alleviate the psycopathology of severe patients.
