Objectives: To date, there is no specific scale to assess the quality of life in Bipolar Disorder
(BD). The Quality of Life in Bipolar Disorder (QoL.BD) is the first questionnaire designed
for this purpose. In this study, we aimed to examine the psychometric properties of the Persian
Brief Quality of Life in Bipolar Disorder (Brief QoL.BD).
Methods: After forward and backward translation of the questionnaire and comparing the two
translations, the Persian version of the questionnaire was prepared to be tested. The statistical
population comprised all patients and normal individuals in Tehran . The sample population
included 118 patients with BD and 132 healthy individuals without the history of mental
disorder; they were selected using a convenience sampling method. The study instruments
included the Beck Depression Inventory-II, Bech–Rafaelsen Mania Rating Scale, the 36-Item
Short-Form Health Survey (SF-36), and the Brief QoL.BD. Data were analyzed using SPSS
and Lisrel statistical programs.
Results: The confirmatory factor analysis indices indicated a relatively good model fit. Content
validity estimates were also acceptable. Convergent validity was examined by calculating the
correlation between the scores on the Brief QoL.BD and those on the SF-36 questionnaire;
the results were found to be significant (r=0.36, P<0.01). Discriminant validity was assessed
by comparing the Brief QoL.BD total scores between the groups of patients with BD and
healthy individuals; the results indicated a significant difference between the two groups
(t=65.09, P<0.01). The Cronbach’s alpha of 0.70 indicated an internal consistency. A test–
retest reliability estimate of 0.89 indicated a high reliability of the scale.
Discussion: The Brief QoL.BD has high validity and reliability in assessing the QoL of
patients with BD in Iran.

808) Due to the fact that assessing the QoL of patients with BD is both important for the diagnosis and examination of treatment outcomes, and given to the lack of Persian disorder-specific scale to assess QoL, the aim of this study was to consider psychometric properties of the Persian version of Brief QoL.
BD, this questionnaire was tested on patient and healthy groups to determine whether there was a sig- nificant difference between them in terms of their total scores on the scale; in other words, we intended to test whether Brief QoL.
