Abstract

Aims: The sitting posture and its related problems are of high importance. The current research was conducted with the aim of design and evaluation of a measurement tool for sitting situation, using validity and reliability.
Instruments and Methods: In this semi-experimental (field trial) study, a number of questions about knowledge, attitude, and behavior were designed and content validity and face validity were utilized to assess the validity. Then, questionnaire was given to 10 specialists in health education, physiotherapists, and ergonomists. Moreover, Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated to determine content validity, and for reliability assessment, two criteria were used, including internal consistency through Cronbach's alpha and test-retest through Intra-class Correlation Coefficient (ICC) and Pearson correlation coefficient. Consequently, 30 students were enrolled in the study. The data were analyzed by SPSS 22 software.
Findings: Firstly, of all 29 questions in terms of knowledge, attitude, and behavior, 23 items remained with CVR higher than 0.6 and CVI tables were higher than 0.7. From 23 items referring to the 3 mentioned spectra, 12 questions were in the field of knowledge, 6 questions were in the field of attitude, and 5 questions were in the field of behavior. Then, the Cronbach's alpha coefficient was 0.87, the ICC was 0.983, and Pearson correlation coefficient was 0.966 (p<0.001).
Conclusion: The designed questionnaire can appropriately examine sitting situation in terms of the knowledge, attitude, and behavior; therefore, it is an excellent tool for measuring these characteristics owing to satisfactory validity and reliability.

Abstract

Aims: A strong association has been documented between diabetes mellitus (DM) and oral diseases. Since dental clinicians are mainly responsible for the oral health of the general population, this study aimed to assess the knowledge and practice of dental students in Tehran regarding the oral health of diabetic patients.
Instrument & Methods: In this cross-sectional study, a researcher-designed questionnaire with 3 domains and 32 questions (5 demographic, 21 knowledge, and 6 practice questions) was used for data collection. After assessing the validity and reliability of the questionnaire, 130 senior dental students attending Tehran, Shahid Beheshti, Shahed, and Islamic Azad University dental schools were requested to fill it out. Data were analyzed by the linear regression model using SPSS version 20.
Findings: The mean age of the participants was 24.6±2.47 years. The response rate was 94%. Half of the students were females (n=70, 53%). The mean knowledge and practice scores of the students were 15.29±2.32 out of 21, and 4±1.19 out of 6, respectively. The students with a higher grade point average score acquired higher knowledge and attitude scores (p=0.00). A significant inverse correlation was found between the practice and the age of students (p=0.05).
Conclusion: The results indicate the moderate level of knowledge and practice of dental students in Tehran regarding the oral health of diabetic patients. Educational interventions and revision of dental curricula may enhance the knowledge and practice of dental students in this respect.
