Basic principles that should be followed by anyone developing a scale are reviewed, with emphasis on verbally mediated measures. The essential first step is a clear conceptualization of the target construct. Item development and ensuring unidimensionality follow. Factor analysis can be crucial in establishing unidimensionality and discriminant validity. (SLD)
