Running Title Psychometric the Stretching Exercise Influencing Scale Study Design Cross sectional- Psychometric properties Abstract Objective: The Lack of reliable and valid tools for assessing the influencing factors which influence on stretching exercises among Iranian office employees is obvious. This study aimed to design and evaluate psychometric properties of this instrument. Design: Cross-sectional study- Psychometric properties Setting: Data were gathered from May to September 2017. Participants: Participants were 420 office employees who were working in 10 health centres affiliated to Shahid Beheshti University of Medical Sciences (SBUMS) in Tehran, Iran. Primary outcome measures: The instrument was designed on the basis of the constructs of the Health Promotion Model (HPM) and extant literature. Exploratory Factor Analysis, Cronbach’s alpha and Intraclass Correlation Coefficient (ICC) were employed to check the scale’s psychometric properties. Results: In total, 420 questionnaires were completed. The mean age of the office employees was 37.1±8.03 years. Among the 86 items, 77 items had significant item-to-total correlations (P <0.05). The results showed good internal consistency and reliability for the whole questionnaire and each domain.EFA results confirmed 53.32% of the total variance of the items yielded in eleven subscales. The (ICC) was acceptable [0.78, 95% CI (0.70, 0.88)]. Conclusions: The SEIS can be a reliable and valid instrument for measuring the influencing factors on stretching exercise among office employees.
Why is it important?
Strengths and limitations of this study: • The SEIS could be a validated and reliable instrument to determine the factors influence on stretching exercise among 420 employees who work with computer in Shahid Beheshti University of Medical Sciences, Tehran, Iran. • In this study, the selected convenience sample just from one university may not reflect all Iranian employee population profile, so the generalization of the present results is limited. • However performing additional studies with computer users from other organizations and with different population profiles, social educational and cultural demographic should be accomplished to confirm the results. • It is also suggested that the SEIS should be justified to other languages and cultures so that it could be applied in other countries.
