“…The prevalence of psychological disorders has been often investigated in beta‐thalassaemia, mainly focusing on anxiety, depression and overall quality of life. (Pakbaz et al , ; Mednick et al , ; Musallam et al , ; Shafiee et al ,; Yengil et al , ; Maheri et al , ) Although studies differed widely for cohort age (mean‐age range from 14 [Pakbaz et al , ; ] to 27 years [Mednick et al , ; ]) and psychometric tools (Beck's Depression Inventory (Shafiee et al ,; Yengil et al , ; Khoury et al , ), State‐Trait Anxiety Inventory (Khoury et al , ), Dartmouth Primary Care Cooperative Information Chart System (COOP) questionnaire (Pakbaz et al , ), Hospital Anxiety Depression Scale (HADS) and quality of life (SF‐36) (Mednick et al , ), symptoms of anxiety and depression were detected among beta‐thalassaemia patients with high prevalence rate (depression 11–35% and anxiety 33–58·8%, Mednick et al , ; Khoury et al , ; Yengil et al , ; ). However, all these studies lacked a control group, missing the opportunity to show the effective role of beta‐thalassaemia in determining these symptoms.…”
