Validation was conducted by means of a field test that resulted in 680 responses from 13 countries, primarily the United States, Australia, New Zealand, and Canada. Fifty six field tested items were reduced to 42 items in seven scales after principle component factor analysis and internal consistency reliability (Cronbachs alpha) analysis. The items with factor loadings ≥ 0.55 within their own scales were kept. Items with factor loadings < 0.55 were discarded. For the seven scales, the alpha reliability coefficient ranged from 0.75 to 0.95.
DELES scales, in the order presented in this survey, are as follows:
Instructor Support items 1-8
Student Interaction & Collaboration items 9-14
Personal Relevance items 15-21
Authentic Learning items 22-26
Active Learning items 27-29
Student Autonomy items 30-34
Student Satisfaction (Enjoyment) items 35-42
Factor Analysis

When analyzing associations between the attitude scale (enjoyment of distance education) and the six psychosocial scales, the correlations ranged from r = 0.12 to 0.31 with the scale of personal relevance having the strongest correlation. Regression coefficients ranged from β = 0.00 to 0.23, again with the scale of personal relevance having the strongest association, followed by authenticity in learning with β = 0.16.
