The purpose of this study was to investigate the internal consistency reliability of the Stages of Concern Questionnaire (SoCQ) when the measure is administered to naive subjects as a pretest. The SoCQ was developed by G. E. Hall, A. A. George, and W. L. Rutherford (1979/1986). In the present study, the SoCQ was administered to secondary school science teachers participating in the pilot of a curriculum model that: (1) exposed students to more hours of science over a longer period of time; (2) immersed students in a program reinforcing the interrelatedness of science disciplines; and (3) built from a descriptive knowledge base toward abstract thought processes. Data are reported for the first three measurement points in the study: point-0 (pretest) data were collected from 22 teachers before the implementation of the revised curriculum; point-1 data were collected from 15 teachers after about 1 week; and point-2 data were collected from 25 teachers, including 12 members of the original cohort, at about 6 months into the implementation of the intervention. The alpha coefficients from the various points gave marginal results, and were particularly unfavorable for the awareness scale. Results neither confirm the plausibility of the concerns model nor indicate that the SoCQ yielded reliable scores for all the model's constructs. A 21-item list of references and 1 table, which summarizes the alpha coefficients, are included. (SLD)
