Reliability and validity of the Overeating Tension Scale.
This study presents the development and testing of the Overeating Tension Scale. Overeating tension was defined operationally as the total discrepancy score resulting from differences between subjects' ratings of actual and desired feelings before overeating. The 32-item Overeating Tension Scale, derived from Apter's Reversal Theory, measures reported overall tension and motivation-specific tension. The scale initially included 48 items, six items for each of eight motivational states. After two instrument development studies (N = 373, N = 208), items were refined and reduced to a total of 32, or four for each of eight motivational states. The final version of the instrument was tested in two additional studies (N = 330, N = 130) that provided evidence to support the internal consistency reliability of the Overeating Tension Scale. There was support for construct validity using contrasted groups (overweight and normal weight subjects), convergent validity, and factor analysis.
