Factorial Validity of the Toronto Alexithymia Scale (TAS-20) in Clinical Samples: A Critical Examination of the Literature and a Psychometric Study in Anorexia Nervosa.

There is extensive use of the 20-item Toronto Alexithymia Scale (TAS-20) in research and clinical practice in anorexia nervosa (AN), though it is not empirically established in this population. This study aims to examine the factorial validity of the TAS-20 in a Portuguese AN sample (N = 125), testing four different models (ranging from 1 to 4 factors) that were identified in critical examination of existing factor analytic studies. Results of confirmatory factor analysis (CFA) suggested that the three-factor solution, measuring difficulty identifying (DIF) and describing feelings (DDF), and externally oriented thinking (EOT), was the best fitting model. The quality of measurement improves if two EOT items (16 and 18) are eliminated. Internal consistency of EOT was low and decreased with age. The results provide support for the factorial validity of the TAS-20 in AN. Nevertheless, the measurement of EOT requires some caution and may be problematic in AN adolescents.

Emotional, inflammatory, and genetic factors of resilience and vulnerability to depression in patients with premenopausal breast cancer: A longitudinal study protocol.

BACKGROUND: Psychosocial stress and depressive disorder have been associated with cancer as putative contributors to worse prognosis. On the other hand, cancer diagnosis is a recognised life event that can contribute to distress and depressive states. Humoral and cellular inflammation can promote depressive disorder by means of decreased monoamine synthesis, glutamate neurotoxicity, neurogenesis and neuroplasticity, dysregulated hypothalamic-pituitary-adrenal axis, and glucocorticoid resistance. This protocol objectives are to observe the interactions between psychosocial variables and biochemical and immunological biomarkers in a longitudinal, prospective design; to identify inflammation-related depression endophenotypes in breast cancer patients and to understand if early diagnosed and treated depression in this population will translate in better inflammation status and better global prognosis. METHODS: Prospective observational cohort, composed by 100 consecutive premenopausal patients, diagnosed with non-distant metastatic breast carcinoma and with no history of major psychopathology or other organic illness. The participants will have an in-person assessment in three different moments, along illness treatment and follow-up, with respect to cytometric, immunologic, and psychosocial parameters and will be tested for depression vulnerability and resilience inflammation-related functional genetic polymorphisms. Additionally, at years 5 and 10 post enrollment, patients`medical records will be assessed. As a control cohort, all patients excluded due to psychiatric history or past psychiatric treatments will have their clinical records assessed at years 5 and 10 after admission. All the data will be managed with the SPSS® software. DISCUSSION AND CONCLUSION: This study is an original longitudinal cohort of breast cancer premenopausal patients, with a comprehensive approach to psychosocial, clinical, inflammatory, and genetic variables. It expects to provide evidence regarding the links between genetic, cytometric, immunologic, and psychosocial factors, their potential contribution to the pathophysiology of depressive disorder, breast cancer course, progression, and prognosis. It may further contribute with data to better efficacy of the psycho-oncological interventions.

Stress-Related Growth Scale-Short Form: A Portuguese validation for cancer patients.

ABSTRACT BACKGROUND/OBJECTIVE: Cancer can be extremely disruptive, triggering high levels of distress, and at the same time transformative, promoting perceptions of positive life changes and growth. This study aims to analyze the psychometric proprieties of the Stress-Related Growth Scale Short-Form (SRGS-SF) in cancer patients. METHOD: 209 Cancer patients heterogeneous in disease stage and diagnosis completed: clinical and sociodemographic information, Distress Thermometer, Positive and Negative Affect Schedule, Visual-analogue Scale of Perceived Positive Life Changes, and Stress-Related Growth Scale-Short Form. RESULTS: The analysis of internal structure pointed to an one-dimensional scale, with high reliability (.92) measured through the McDonald`s omega coefficient. Validity was also evidenced through significant correlations with other variables. CONCLUSIONS: The Portuguese version of the SRGS-SF seems to present the necessary psychometric proprieties to be considered a valid and reliable short tool, to assess perceptions of growth following cancer and contribute to targeted and integrative psycho-oncological interventions.

RESUMEN ANTECEDENTES/OBJETIVO: El cáncer puede ser extremadamente disruptivo y transformador al mismo tiempo, provocando altos niveles de angustia que pueden promover la percepción de cambios positivos en la vida y crecimiento. Este estudio tiene como objetivo analizar las propiedades psicométricas de la Stress-Related Growth Scale-Short Form (SRGS-SF) en pacientes con cáncer. MÉTODO: 209 pacientes con cáncer heterogéneo en estadio de la enfermedad y diagnóstico han completado información clínica y sociodemográfica, Distress Thermometer, Positive and Negative Affect Schedule, Escala visual-analógica de los cambios de vida positivos percibidos y Stress-Related Growth Scale-Short Form. RESULTADOS: El análisis de la estructura interna apuntó una estructura unifactorial con índices de ajuste adecuados y una alta fiabilidad (.92) evaluada a través del coeficiente omega de McDonald. La validez fue proporcionada a través de la evidencia de correlaciones significativas con otras variables. CONCLUSIONES: La versión portuguesa del SRGS-SF parece presentar las propiedades psicométricas necesarias para ser considerada una herramienta corta válida y confiable, para evaluar las percepciones de crecimiento después del cáncer y contribuir para intervenciones psico-oncológicas específicas e integradoras.

Smoking Abstinence Twelve Months after an Acute Coronary Syndrome.

Studies on the cognitive working mechanism of smoking cessation in high-risk populations are few and much needed, and identifying long-term psychosocial factors to smoking cessation are relevant to improve intervention for cardiac patient groups. This longitudinal study followed patients who smoked and suffered an acute coronary syndrome from hospitalization to 12 months after clinical discharge. Questionnaires were administered to assess nicotine dependence, behavioral dependence, autonomous self-regulation, perceived competence, social support, anxiety, depressive symptoms and meaning in life at baseline, six months and twelve months after clinical discharge. The results showed that anxiety (F(2, 62) = 28.10, p < .001, η p 2 = .48) and depressive symptoms (F(2, 62) = 10.42, p < .001, η p 2 = .25) decreased over time, whereas meaning in life (F(2, 61) = 44.77, p < .001, η p 2 = .59) and social support increased (t(63) = -4.54, p < .001, 95% IC[-11.05, 4.29], η2 =.25). Smoking dependence was negatively predicted by change in perceived competence (B = -2.25, p = .011, 95% IC[.02, .60]) and positively by change in depressive symptoms (B =.37, p = .042, 95% IC[1.01, 2.05]) 12 months after clinical discharge. Nicotine dependence (t(17) = 2.76, p = .014, 95% IC[.39, 2.94], η2 =.31) and the number of cigarettes smoked per day (t(17) = 4.48, p < .001, 95% IC[5.49, 15.29], η2 =.54) decreased over time, whereas behavioral dependence increased among smokers (t(17) = -2.37, p = .030, 95% IC[-4.30, 2.54], η2 =.25). This study suggests that long term abstinence in cardiac patients may be enhanced by psychological interventions addressing perceived competence, depressive symptoms and behavioral dependence.

Validation of the Glover-Nilsson Smoking Behavioral Questionnaire for the Portuguese population: a psychometric process.

OBJECTIVE: To validate the Portuguese version of the Glover-Nilsson Smoking Behavioral Questionnaire (GNSBQ). METHODS: This manuscript represents 2 studies. In the first, the free-translated Portuguese version of GNSBQ, currently in use, was administered to 124 healthy smokers for Confirmatory Factor Analysis (CFA). In the second, a forward-backward translation was developed to achieve a proper cultural and linguistic adaptation, which allowed creating a new Portuguese version of the GNSBQ. An Exploratory Factor Analysis (EFA) was then performed, including 120 healthy smokers who completed this new version. RESULTS: In the first study, the results from performing a CFA were not acceptable, although the scale was internally consistent. The second study showed that the new Portuguese version of GNSBQ presented reliability and 2 cor-related factors retrieved from the EFA. CONCLUSION: The new Portuguese version of the second study will contribute to an improved assessment of behavioral dependence in that population.
