Resumen
Background: The Quality of life Bipolar Disorder (QoL.BD) Questionnaire
specifically measures quality of life in patients with bipolar disorder. Aim: To
adapt a version translated into Spanish of the questionnaire and assess its validity
in Chilean patients. Material and Methods: The QoL. BD was adapted to the
Chilean population through the back-translation method and then administered
to 32 adult patients with a bipolar disorder and 31 subjects without the disease,
both groups with similar socioeconomic status. To confirm the diagnosis, the
International Neuropsychiatric Interview (MINI), Young (YMRS) and Hamilton
(HAM-D) scales were applied. Quality of life was assessed using the SF-36v.2
survey. We determined internal consistency, reliability, convergent validity, the
cut-off point, and the sensibility and specificity of the scale. Results: The Chilean
version of the Questionnaire [QoL. BD-CL] had a high reliability (α = 0.95)
and a high validity in reference to external criteria (correlation coefficients with
SF-36 ranging from 0.453 and 0.819; p < 0.01). A cut-off point of 170, with
sensitivity of 87.9% and specificity of 80% was determined. Conclusions: QoL.
BD-CL has adequate psychometric properties, as well as an adequate sensitivity
and specificity to distinguish between negative and positive perceptions of life
quality in Chilean patients with bipolar disorders.
