The authors developed and validated a questionnaire called “The Jordanian Food Purchasing Habits Survey” (JFPHS). The purpose of this questionnaire was to explore Jordanians’ food purchasing habits and the factors which may affect these habits among a convenient sample of people. To the best of the authors’ knowledge, no such questionnaires have been developed to measure these factors for the Jordanian population. This paper aims to describe the reasoning behind and the process of developing the (JFPHS).
The JFPHS investigated meal preparation and grocery shopping behaviors, nutrition label use and factors affecting purchasing of 13 (n = 13) food groups. A two-step process, a pilot test and validity study, were used to validate the questionnaire. Internal consistency (split-half reliability) tests were run on the factors in each individual food group producing Spearman–Brown correlation coefficients.
A convenient sample of 483 individuals (118 males, 365 females) participated in the study. Spearman–Brown correlation coefficients were < 0.7 for bread and between 0.7–0.8 and 0.8–0.9 for other food groups. The ingredients list grid and the expiry date grid had Spearman–Brown coefficient values > 0.9.
This questionnaire is a valid tool to assess food purchasing behavior. Results from our questionnaire, when published, may be used to monitor trends in food consumption.
To the best of the authors’ knowledge, no such questionnaires been developed to measure these factors for the Jordanian population.
