    The validity and reliability of the Turkish version of the Seattle Angina Questionnaire

    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.

    The validity and reliability of the Turkish version of the Arthritis Impact Measurement Scale 2-Short Form (AIMS2-SF) for rheumatoid arthritis
    (2023-04-01) ŞANAL TOPRAK, CANAN; ÖZ, NURAN; DURUÖZ, MEHMET TUNCAY; ŞANAL TOPRAK C., Unal-Ulutatar Ç., Duruöz E., ÖZ N., DURUÖZ M. T.
    The objective of this study is to investigate the validity and reliability of the Turkish version of the Arthritis Impact Measurement Scale 2-Short Form (AIMS2-SF). Subjects fulfilling the ACR 2010 classification criteria for RA were enrolled into the study. Scale reliability was investigated using test–retest reliability (intra-class correlation coefficient—ICC) and internal consistency approaches (Cronbach’s α). Spearman’s rank correlation coefficients evaluated relationships between quantitative parameters and validity. Construct validity was assessed by correlating AIMS2-SF with clinical parameters and functional parameters including, Nottingham Health Profile (NHP), Health Assessment Questionnaire (HAQ), Beck Depression Inventory (BDI) and Duruöz Hand Index (DHI). One hundred and sixteen patients (105 females and 11 males) were recruited. The mean age ± standard deviation (SD) was 52.45 ± 11.48 years. Cronbach’s α was 0.88 and the ICC was 0.91. There were significant correlations (rho and p values) with parameters directly related to health-related quality of life (HRQoL); NHP subscales (energy levels: 0.54, pain: 0.62, emotional reaction: 0.50, sleep 0.44, social interaction: 0.51, physical activity: 0.61; p < 0.0005), HAQ (0.60, p < 0.0005), BDI (0.63, p < 0.001) and DHI (0.63, p < 0.0005). Poor or non-significant correlations were found for parameters not directly related to QoL, such as age (0.07, p = 0.45) and disease duration (0.12, p = 0.21); however, disease activity (0.43, p < 0.0005) and NRS pain (0.46, p < 0.0005) were correlated with AIMS2-SF as moderate. The Turkish AIMS2-SF version is a reliable and valid tool that may be used to evaluate QoL for RA. The scale can be easily used in daily practice.
