Intervenciones familiares en el tratamiento de los pacientes con esquizofrenia: aproximaciones recientes

Resumen

Después de mencionar los postulados básicos que subyacen a los modelos tradicionales de terapia familiar a los que se han planteado serias críticas, se revisan nuevos modelos que superan estas limitaciones. Estos nuevos modelos de intervención familiar comparten dos características principales: considerar a los familiares aliados naturales del proceso de rehabilitación del paciente y basarse en el empleo de estrategias terapéuticas claramente operacionalizadas. Se describen brevemente cuatro de estas estrategias y se revisa la evidencia que apoya su eficacia: la terapia familiar orientada a la crisis de Goldstein, el paquete de intervenciones psicosociales desarrollado por Leff y cols., la terapia familiar conductual de Falloom y el programa de psicoeducación familiar de Anderson y cols. Su eficacia es analizada en términos de la disminución observada en las tasas de recaídas y en la consecución de otros beneficios para el paciente y la familia. Se señalan un conjunto de principios generales que deben presidir las intervenciones con estas familias. Por último, se hace una reflexión acerca de algunas deficiencias que estudios futuros han de subsanar para poder alcanzar unas conclusiones más sólidas sobre la eficacia de estos nuevos procedimientos terapéuticos.     

Men and masculinities: Scales for masculinity ideology and masculinity-related constructs

11 instruments for assessing beliefs and attitudes about men or masculinity standards (masculinity ideology) and 6 instruments that assess first-person accounts of gender role conflict, stress, or conformity to masculinity ideology are evaluated in this review. The 17 instruments were all developed in the past 2 decades and peer reviewed, and are readily accessible. An introductory section distinguishes between gender ideology and gender orientation and defines the scope of the first set of 11 scales as indexing the extent to which subjects accept the ideas and beliefs used to justify gender roles and relations. The second set of 6 scales focus on how men individually experience their gender. All scales were systematically evaluated according to whether they include items comparing the sexes or concerning gender relations or items assessing attitudes and beliefs about women. Inclusion of these types of items is noted in a table, along with information on whether the authors assumed one dominant form of masculinity, whether subscales were identified, and the psychometric properties of the scale and subscale. The review suggests that measures of gender orientation and measures of gender ideologies are independent and have differential correlates. Evidence also suggests that gender ideologies about men are distinct from and have differential correlates from gender ideologies about women or about gender relations in general. Items comparing genders should thus be avoided in measures of attitude toward masculinities. Several of the measures have too narrow a definition of masculinity.     

Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.
