Abstract

Objective: This study aimed to evaluate the psychometric properties of the Persian version of the TSQM-14 in patients with hypertension in Iran.

Methods: This cross-sectional study was conducted among hypertensive patients referred to primary healthcare centers in Kerman City between January and February 2021. Cronbach's alpha and total-item correlation were used to evaluate internal consistency, while the Intraclass Correlation Coefficient (ICC) was employed to assess test-retest reliability. Construct validity was examined using structural equation modeling (SEM), known-groups validity, and convergent validity.

Results: A total of 319 participants took part in the study, with a mean age of 56.7 years (SD = 13.0), and 57.7% (n = 184) were female. The Cronbach's alpha and ICC values of the TSQM-14 for the composite scales were 0.83 and 0.91, respectively, indicating good reliability. The SEM indices for TSQM-14 demonstrated adequate model fit, with χ² = 118.9 (P ≤ 0.001), CFI = 0.96, RMSEA = 0.07, TLI = 0.95, and NFI = 0.91. The mean (standard deviation (SD)) scores of the composite scale for patients in the uncontrolled group (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg) and the controlled group were 50.2 (SD = 6.6) and 47.6 (SD = 6.1), respectively (P = 0.021). Additionally, the Spearman correlation coefficient between the TSQM-14 scale and the MMAS-8 was 0.30 (P < 0.001), demonstrating a weak but significant correlation.

Conclusions: This study demonstrated that the Persian version of the TSQM-14 has acceptable reliability, as well as construct and convergent validity, for assessing treatment satisfaction among hypertensive patients.

期刊介绍： Chronic illnesses are prolonged, do not resolve spontaneously, and are rarely completely cured. The most common are cardiovascular diseases (hypertension, coronary artery disease, stroke and heart failure), the arthritides, asthma and chronic obstructive pulmonary disease, diabetes and epilepsy. There is increasing evidence that mental illnesses such as depression are best understood as chronic health problems. HIV/AIDS has become a chronic condition in those countries where effective medication is available.
