Validación de la versión española del cuestionario King's Health para la evaluación de la calidad de vida relacionada con la incontinencia urinaria en pacientes con lesión medular

Abstract

Background and objective To determine the validity of the Spanish version of the King's Health Questionnaire (KHQ) in patients with spinal cord injury. Patients and methods A cross-sectional study, including a total of 120 patients with spinal cord injury. The feasibility, cross-cultural validity, and internal consistency of the KHQ were evaluated. Results The dimensions with the highest scores were: impact of urinary symptoms, personal relations, and physical limitations. The following groups presented a significantly poorer HRQoL: persons of advanced age in personal relations (P = 0.042), women in limitations of daily life activities (P = 0.009) and in the impact of urinary incontinence (P < 0.01), paraplegic patients in personal relations, and patients with incomplete cord lesions in sleeping and energy (P < 0.01). Patients with an external condom catheter presented a better HRQoL with significant differences in the dimension, limitations of daily life activities (P = 0.04). The KHQ showed good internal consistency (Cronbach alpha 0.91). Conclusion KHQ is a valid instrument for evaluating HRQoL related with urinary incontinence in patients with spinal cord injury.
