Objectives Cognitive and emotional disturbances have been associated with the diagnosis and treatment of cancer. Autobiographical memory is one of the specific cognitive processes affected during this disease. The current study had two main aims: (1) to compare the functioning of autobiographical memory specificity and its related variables (executive functioning, depression and perceived stress) in a group of persons with cancer and a control group; and (2) to analyze whether the experience of cancer evolved into a self-defining memory in the sample of participants diagnosed with this disease. Method The study sample comprised 62 participants, 31 in the group with a cancer diagnosis and 31 in the control group. Autobiographical memory specificity, executive functions, depression, stress and self-defining memory were evaluated in the current study. Results Depressive symptomatology and reduced executive functioning, but not perceived stress levels, are related and are predictors of autobiographical memory specificity. In addition, the identified characteristics of the self-defining memories were associated with the cancer experience as a threat to physical integrity and an awareness of the meaning of life. Conclusion This emerging research line is especially important in view of its possible impacts on patients’ well-being, due to the importance of psychological processes in cancer disease.

Fundamento y objetivo: Elaborar y validar una escala para detectar trastornos depresivos mayores (TDM) en ancianos que utilizan las consultas de atención primaria (Escala para la Detección de Depresión en Ancianos [EDDA]). Métodos: Estudio observacional transversal para validar una escala, administrada mediante entrevista personal, en 259 pacientes de 65 o más años. Tras revisar los instrumentos disponibles y elaborar los ítems, se realizó una primera prueba piloto o pretest. En una segunda prueba piloto se analizó la reproducibilidad del instrumento. El estándar de oro fue el resultado de una entrevista psiquiátrica estandarizada realizada por psiquiatras (criterios DSM-IV y entrevista SCAN). Resultados: Los coeficientes de correlación intraclase (CCI) correspondientes a la fiabilidad intra e interobservador fueron, respectivamente, de 0,858 (intervalo de confianza [IC] del 95%, 0,634-0,946) y 0,908 (IC del 95%, 0,726-0,969). El número de sujetos válidos para el estudio fue de 216 ancianos, en quienes se realizó, de forma ciega, una valoración en consultas de atención primaria y de psiquiatría. En éstas se objetivó la existencia de un TDM en 81 de ellos (37,5%; IC del 95%, 31,1-44,4). La EDDA mostró una elevada coherencia interna (* de Cronbach = 0,79). El análisis factorial determinó que existían 8 factores capaces de explicar el 55,8% de la varianza total. Para una puntuación mayor o igual a 15, la EDDA presenta una sensibilidad del 90,1% (IC del 95%, 80,95-95,33), una especificidad del 74,8% (IC del 95%, 66,48-81,71) y un cociente de probabilidad positivo de 3,58 (IC del 95%, 2,65-4,83). Conclusiones: La EDDA es un instrumento clínicamente útil para la detectar los TDM de los ancianos en la atención primaria.Background and objective: The aim of this study was to design and validate a scale to detect major depressive disorders in elderly individuals in primary care (Detection of Depression in the Elderly Scale [DDES]). Methods: We performed an observational and cross-sectional study for the validation of a scale, administered by means of a personal interview, in 259 patients aged 65 years old or older. Available instruments were reviewed and the questions were designed. Subsequently, a first pilot study was performed. In a second pilot study the reproducibility of the instrument was analyzed. The gold standard was the result of a standardized psychiatric interview performed by psychiatrists (DSM-IV criteria and SCAN interviews). Results: The intraclass correlation coefficients corresponding to the test-retest and inter-rater reliability were 0.858 (95% confidence interval [CI], 0.634-0.946) and 0.908 (95% CI, 0.726-0.969) respectively. Two hundred sixteen subjects underwent an assessment, in which primary care and psychiatric evaluations were blinded. Major depression was diagnosed in 81 patients (37.5%; 95% CI, 31.1-44.4). The internal consistency of the DDES was good (Cronbach's alpha = 0.79). Exploratory factorial analysis revealed an 8-component structure (55.8% of explained variance). A cutoff score of 15 or more for the DDES showed sensitivity of 90.1% (95% CI, 80.95-95.33), specificity of 74.8% (95% CI, 66.48-81.71) and a likelihood ratio (+) of 3.58 (95% CI, 2.65-4.83). Conclusions: The DDES is a clinically useful instrument for the detection of major depression in elderly patients in primary care.
