Sj. Mckelvie, GUIDELINES FOR JUDGING PSYCHOMETRIC PROPERTIES OF IMAGERY QUESTIONNAIRES AS RESEARCH INSTRUMENTS - A QUANTITATIVE PROPOSAL, Perceptual and motor skills, 79(3), 1994, pp. 1219-1231

imagery questionnaires in the context of their use as research instru
ments, standards are proposed for correlation coefficients under the h
eadings of reliability, criterion validity, and content validity. Guid

mmended.
