    The validity and reliability of the Turkish version of the Seattle Angina Questionnaire
    (TURKISH SOC CARDIOLOGY, 2020) ŞANAL TOPRAK, CANAN; Duruoz, Mehmet Tuncay; Toprak, Canan Sanal; Ulutatar, Firat; Suhaimi, Anwar; Agirbasli, Mehmet
    Objective: The purpose of this study was to assess the validity and reliability of a Turkish version of the Seattle Angina Questionnaire (SAQ) in patients with coronary heart disease (CHD) and angina. Methods: The SAQ was translated from English to Turkish using the back-translation method. It contains 19 questions scored from 1 to either 5 or 6 in 5 domains (physical limitation, angina stability, angina frequency, disease perception, and treatment satisfaction). Cronbach's alpha coefficient was used to evaluate internal consistency. Spearman's rank correlation coefficient was calculated to assess the construct validity. Convergent validity was examined using correlations between the SAQ and the MacNew Heart Disease Health-related Quality of Life Questionnaire (MacNew) and the Nottingham Health Profile. Divergent validity was evaluated using correlations between the SAQ and age, body mass index (BMI), gender, and the marital status of patients. A value of p<0.05 was considered statistically significant. Results: Sixty-seven patients were enrolled in the study. The mean age of the study patients was 58.7 years (SD: 10.2). Cronbach's alpha scores of the SAQ, ranging in value from 0.715 to 0.910, demonstrated that this scale is reliable. All of the SAQ scales had a significant correlation with all of the MacNew scales, which indicated that the scale has convergent validity. Insignificant correlations with age, BMI, gender, and marital status illustrated the good divergent validity of the scale. Conclusion: The Turkish version of the SAQ is a valid and reliable instrument. It is a useful and practical tool to evaluate patients with angina and CHD.

    Duruoz Hand Index: Is it valid and reliable in children with unilateral cerebral palsy?
    (TAYLOR & FRANCIS INC, 2019) ŞANAL TOPRAK, CANAN; Sanal-Top, Canan; Karadag-Saygi, Evrim; Sacaklidir, Rekib; Duruoz, Mehmet Tuncay
    Purpose: To investigate the validity and reliability of the Duruoz Hand Index (DHI) in patients with unilateral cerebral palsy (CP). Methods: Assessments of patients (n = 23) were performed using the Modified Ashworth Scale (MAS), the Manual Ability Classification System (MACS), the grip and pinch strength tests, and DHI. Following the data collection, retest of DHI was administered telephonically within a 2-week period. Results: Test-retest reliability and internal consistency of DHI were found to be excellent with a Cronbach's alpha value of 0.93 and an intraclass correlation coefficient value of 0.94. The correlation between the DHI and MACS was detected significantly high (r = 0.840, p = < 0.010). The DHI also correlated with grip and pinch strength in the affected side (r = -0.459, p = r = -0.509, p = < 0.050). Conclusions: DHI is a valid and reliable questionnaire for patients with unilateral CP.
