2) Zarit Burden Interview: Although there are various scales evaluating care burden, only few of them have validity and reliability studies in Turkey. This scale was selected in this study due to its previous utilization in the literature in chronic psychiatric disorders such as schizophrenia (10). Turkish validity and reliability study of this scale was developed by Zarit et al. (11) to assess subjective burden of caregiver in chronic diseases and its validity and reliability study in Turkish was published as well (12). Scale consists of 22 items and total score is between 0 and 88 and the higher the score the higher subjective burden exposed. Zarit proposed to group care burden as severe burden for scores between 61 and 88, moderate to severe burden for scores between 41 and 60 and mild to moderate burden for scores between 21 and 40 (11).
