Abstract

El distrés es una experiencia emocional desagradable que puede afectar al afrontamiento y curso de una enfermedad oncológica. El Inventario Breve de Síntomas (BSI-18) es usado frecuentemente en pacientes oncológicos para medir distrés. No obstante, su estructura factorial no está bien establecida, y sus propiedades métricas no han sido estudiadas con muestras mexicanas. La presente investigación tiene como objetivos estudiar la distribución, discriminabilidad y homogeneidad de los ítems del BSI-18, estimar la consistencia interna del BSI-18, determinar su estructura factorial y calcular la validez convergente, discriminante y consistencia interna de sus factores. Se recolectó una muestra intencional de 203 mujeres con cáncer de mama en tratamiento oncológico. Todas ellas eran adultas tratadas en la ciudad de Monterrey, México. Todos los ítems del BSI-18 resultaron discriminativos y consistentes. Sus distribuciones mostraron mayor concentración en valores bajos. La consistencia interna de la escala fue alta (α de Cronbach=0,888). El modelo de un factor general de distrés con tres factores jerarquizados (depresión, síntomas simpáticos de ansiedad y síntomas vasovagales de ansiedad) mostró las mejores propiedades de bondad de ajuste. También sus factores tuvieron las mejores propiedades de validez convergente y consistencia interna. Además, este modelo permitió superar los problemas de validez discriminante entre los factores. Se concluye que, en la población estudiada de mujeres diagnosticadas con cáncer, se pueden retener todos los ítems del BSI-18, y la escala resultó consistente y válida desde un modelo jerarquizado de tres factores.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
