title: [Assessment of a version adapted and translated into Spanish of the Quality of Life Bipolar Disorder Questionnaire].
abstract: BACKGROUND
  The Quality of life Bipolar Disorder (QoL.BD) Questionnaire specifically measures quality of life in patients with bipolar disorder.
  
  
  OBJECTIVE
  To adapt a version translated into Spanish of the questionnaire and assess its validity in Chilean patients.
  
  
  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.
