Assessing the Validity and Reliability of a Socio-Cognitive Determinants of Water Intake Questionnaire in Kidney Stones Patients
Background
Developing a valid and reliable questionnaire is an important step in field studies, which can help to tailor health-related behavior interventions. This study aimed at the psychometric analysis of the socio-cognitive determinants of water intake questionnaire behaviors among patients with kidney stones in the west of Iran.
Methods
Items were generated from interviews with kidney stones patients and experts. As well as, our items pool were developed from the questionnaires of socio-cognitive determinants related to the water intake. Internal consistency, face, content, and construct validities were tested. Data were analyzed by SPSS (ver. 20.0).
Results
Based on Eigen values of ≥ 1.00 and factor loadings of ≥ 0.40, five determinants were extracted. The calculated Kaiser–Meyer–Olkin (KMO) value was 0.697. The socio-cognitive determinants of water intake questionnaires were found to have acceptable internal consistency (Cronbach alpha of determinants between 0.65-0.85) and the theoretical assumptions for face, content, and construct validities were confirmed. Overall, the five studied socio-cognitive determinants explained 73.83% of the variance in the proposed model.
Conclusions
The socio-cognitive determinants of water intake questionnaire were revealed to have an acceptable psychometric evaluation. The questionnaire could be used to predict or explain water intake behavior in order to develop programs to increase water intake behavior among kidney stones patients.
