Abstract:
Background and Objective

Regular use of household cleaning products and cosmetics can result in adverse consequences for human health. Therefore, the knowledge of consumption pattern of these products can help to evaluate the effects and finally control the consequences of their inappropriate application. As there is not an appropriate tool for evaluating public use-pattern for these products in Iran, we studied the reliability and validity of a questionnaire designed for the use-patterns of these products.

Materials and Methods

In the present study, a questionnaire, which was previously applied in similar studies for this purpose, was first translated to Persian. Then, some changes were made in the questionnaire according to the studied population. In the next step, the assessment of both content validity and face validity of the instrument was performed. Finally, the questionnaire reliability was studied in two test-retest steps at a 14-day interval with 40 subjects older than 14 years old being resident in Tehran city.

Results

Total Content Validity Index (CVI) of this questionnaire ranged 0.66-1 for all question items. Cronbach's alpha coefficient was 0.814. The correlation assessment of each question item based on the total correlation score showed that all questionnaire items had a direct and strong correlation with the total instrument score.

Conclusion

Given the acceptable validity and reliability obtained for the questionnaire in Persian in this study, it can be used in those investigations that evaluate use patterns or asses the exposure risks to chemical pollutants from cosmetic products or detergents.
