Using methodological triangulation for cultural verification of commitment to a plan for exercise scale among Korean adults with chronic diseases

Abstract

The purpose of this study was twofold: to use methodological triangulation to increase the cultural appropriateness of the Planning for Exercise Scale (Pender, 1996), which measures commitment to a plan of action, and to psychometrically evaluate the revised scale in a selected population of 230 Korean adults experiencing chronic diseases. First, through a qualitative approach, the cultural properties of the concept were identified in order to revise Pender's Planning for Exercise Scale. The revised scale consisted of 20 items: 13 items emerged from the qualitative procedure and seven items were retained from the original scale. Through a quantitative approach, the revised scale was analyzed psychometrically. Results showed the scale had sufficient reliability and validity to warrant its use by researchers or practitioners evaluating the level of commitment to a plan for exercise among Korean adults. The revised instrument is appropriate for use in future intervention studies designed to improve the performance of exercise among Koreans who are chronically ill.
