Abstract
El presente trabajo de Tesis Doctoral se enmarca en la perspectiva de la Psicología de la Salud orientada al estudio de la ansiedad y de la depresión en adultos de atención primaria. Como objetivos el presente estudio se propuso conocer los niveles de depresión y ansiedad en pacientes adultos de atención primaria de Caracas – Venezuela, para ello se agrupo las distintas actividades realizadas en este trabajo en tres estudios. En el primer estudio se analizaron evidencias de validez psicométrica del Cuestionario de Salud General de Goldberg (GHQ-28) en Venezuela. En una muestra de 441 participantes se realizó la adaptación y validación del instrumento utilizando el método de modelos de ecuaciones estructurales. El siguiente estudio, consistió en adaptar y proporcionar evidencias de validez al Cuestionario de Salud de Pacientes (PHQ) en el contexto venezolano con énfasis en la escala de ansiedad y depresión mayor. Para ello se realizaron distintos procedimientos, como estudio de la fiabilidad a partir de la consistencia interna y método de dos mitades, análisis de la validez convergente para lo cual se utilizaron los criterios obtenidos del GHQ-28 en una muestra de 318 participantes. En otra muestra de 80 participantes se estimó la curva COR (Curva Característica Operativa del Receptor) utilizando como criterio un diagnóstico realizado a partir de la entrevista M.I.N.I Plus (Mini International Neuropsychiatric Interview)...

The objectives were to study the levels of depression and anxiety in adult primary care patients in Caracas, Venezuela, for which the different activities were grouped in three studies. In the first study, evidence of the psychometric validity of the Goldberg General Health Questionnaire (GHQ-28) in Venezuela was analyzed. In a sample of 441 participants, the adaptation and validation of the instrument was performed using the structural equation modeling method The following study consisted in adapting and providing evidence of validity to the Patient Health Questionnaire (PHQ) in the Venezuelan context with emphasis on the scale of anxiety and major depression. Different procedures were performed, such as reliability study based on internal consistency and two-halves method, convergent validity analysis for which the criteria obtained from GHQ-28 were used in a sample of 318 participants. In another sample of 80 participants, the COR curve (Operative Operative Curve of the Receiver) was estimated using a diagnosis made from the M.I.N.I (Mini International Neuropsychiatric Interview) interview. In the third study, subscales PHQ-9 and GAD-7 were applied in a sample of 814 participants, patients from a primary care center. The sample found that 10.6% had major depression and 7% had generalized anxiety disorders. When analyzing the results by sociodemographic variables such as gender, age and marital status, some differences were found, but not statistically significant. The results are discussed in light of the international prevalence studies and the divergences are discussed...
