Quality of Life in European Older Adults of SHARE Wave 7: Comparing the Old and the Oldest-Old

2021

CASP-12 (Control, Autonomy, Self-realization, and Pleasure scale) is one of the most common internationally used measures for quality of life in older adults, although its structure is not clearly established. Current research aims to test the factor structure of the CASP-12, so as to provide evidence on reliability and external validity, and to test for measurement invariance across age groups. Data from 61,355 Europeans (≥60 years old) from the Survey of Health, Ageing and Retirement in Europe wave 7 were used. CASP-12, EURO-D (European depression scale), self-perceived health, and life satisfaction measurements were included. Reliability and validity coefficients, competing confirmatory …

Trait driving anger and driving styles among Colombian professional drivers

2019

Abstract This study analyzes the association between trait driving anger and driving styles in a sample of Colombian professional drivers. Additionally, the internal and external validity of the Deffenbacher's Driving Anger Scale (DAS-14) was examined in the study population. The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent stru…

Importance of considering interoceptive abilities in alexithymia assessment

2019

Background Recent studies have shown that people with high alexithymia scores have decreased interoceptive abilities, which can be associated with psychological and physical disorders. Early assessments of the alexithymia trait included the evaluation of these abilities through the dimension measuring the difficulty in identifying and distinguishing between feelings and bodily sensations (the 26-item Toronto Alexithymia Scale; TAS-26). The revised version of the TAS, the TAS-20, contains a three-factor solution that does not involve a dimension assessing interoceptive abilities. However, the three items allowing the evaluation of these abilities are still present in the TAS-20. In this con…

The patient-doctor relationship (PDR) as perceived by the patient is an important concept in primary care and psychotherapy. The PDR Questionnaire (PDRQ-9) provides a brief measure of the therapeutic aspects of the PDR in primary care. We assessed the internal and external validity of the German version of the PDRQ-9 in a representative cross-sectional German population survey that included 2,275 persons aged>=14 years who reported consulting with a primary care physician (PCP). The acceptance of the German version of this questionnaire was good. Confirmatory factor analysis demonstrated that the PRDQ-9 was unidimensional. The internal reliability (Cronbach's ?) of the total score was .95. …

Couple therapy for depression in a naturalistic setting in Finland: a 2-year randomized trial

2012

The dialogical and narrative processes in couple therapy (CT) for depressions project was conducted to develop therapy for depression and to investigate the effectiveness of CT in everyday clinical practice; thus aiming at high external validity. Patients with moderate or major depression were randomized to a CT group (n = 29) and a control group (n = 22). The CT group needed significantly fewer therapy sessions. There were significant differences in favour of the CT group in terms of general mental health (symptom check list), Hamilton depression rating scale, global assessment of functioning and decreasing alcohol use. As regards depressive symptoms using the Beck depression inventory, 79…

La validación transcultural de intervenciones clínicas basadas en evidencia para el tratamiento de trastornos de ansiedad

2014

Las aplicaciones de tecnologías avanzadas han generado la emergencia de un espacio de investigación en ciencias del comportamiento. El creciente acervo de publicaciones, sobre la eficacia y eficiencia de programas de intervención para una serie de trastornos psicológicos, plan- tea la necesidad de fortalecerlos, evaluando su generalización a otros contextos culturales para contribuir a la medición de la validez externa. Mediante la colaboración de dos grupos de investi- gación, se realizó la validación transcultural de tres intervenciones empleando realidad virtual para el tratamiento de miedo a volar, agorafobia y miedo a hablar en público con un programa auto-apli- cado, que demostraron p…
