Sažetak
The primary goals of this study were to adapt the Quality of Life in Epilepsy Inventory – 31 items (QOLIE-31) questionnaire
to the Croatian language and to assess the translated questionnaire’s psychometric properties. Translation/
retranslation of the English version of the QOLIE-31 was done, and all steps for cross-cultural adaptation process were
performed properly by an expert committee. Later, QOLIE-31 questionnaires and previously validated Short Form-36
(SF-36) outcome instruments were given to 200 patients with epilepsy. 172 patients (86%) responded to the first set of
questionnaires, and 114 of the first time respondents (66%) returned their second survey. The two measures of reliability
as internal consistency and reproducibility were determined by Cronbach a statistics and intraclass correlation coefficient,
respectively. Concurrent validity was measured by comparing with a SF-36 questionnaire, and measurement was
made using the Pearson correlation coefficient (r). The study demonstrated satisfactory internal consistency with high
Cronbach a values for all of the corresponding domains (seizure worry 0.84, medication effects 0.80, emotional well-being
0.73, energy/fatigue 0.76, cognitive functioning 0.71, social functioning 0.77, overall quality of life 0.65). The intraclass
correlation coefficient for six domains of QOLIE-31 questionnaire demonstrated excellent test/retest reproducibility
(ICC  0.75), and good test/retest reproducibility (ICC 0.71) in one domain (cognitive functioning). Considering concurrent
validity, three domains had excellent correlation (r=0.75–1), while 11 had good correlation (r=0.50 to 0.75), and 3
had moderate correlation (r=0.25–0.50). This study demonstrated that, if measures are to be used across cultures, the
items must not only be translated well linguistically but also must be culturally adapted to maintain the content validity
of the instrument at a conceptual level across different cultures. Croatian version of QOLIE-31 will be a valuable contribution
to outcome measurement in epilepsy patients, particularly in the context of treatment trials, but als in a wider research
context.
