Measuring Quality of the Agricultural Extension Pamphlets: Scale Construction and Standardization

In Egypt, pamphlets are often used to disseminate agricultural information to farmers. The aim of this study was to construct and develop a scale of quality standards for agricultural extension pamphlets. The process to construct the scale involved the following steps: (۱) The articulation of the construct; (۲) Selection of response format; (۳) Data collection; and (۴) Psychometric analysis. The scale consists of ۳۳ items measuring five domains: content; processing the information; the appearance of text; illustrations; and designing and formatting. Items analysis, reliability, and validity estimates were obtained by a group of experts (N= ۷۸). The reliability of the domains was strong and ranged from (α= ۰.۸۱ to α= ۰.۹۱). The authors tested validation process by evidence of content validity, criterion-related validity, construct validity, and discriminant validity. Depending on the reliability and validity results, the scale was suggested as a reliable tool for assessing the quality of agricultural extension pamphlets. Implications for practice in planning and evaluation of printed materials for agricultural extension work are discussed.
