Pilot Study (n = 50)
A pilot study was undertaken to refine the wording of ques- tions and items and identify deficiencies in the survey (Creswell 1994). For each item, the central tendency and dispersion were checked and exploratory factor analysis was performed to ensure that the items used to measure each construct were unidimensional and reliable measures of that construct based on acceptable ranges (Hair, Anderson, Tatham, and Black 1995).
