A revised scale for the measurement of ecological attitudes and knowledge.

Describes a revised short-form version of the authors' original scale (see record 1974-05007-001) for the assessment of ecological attitudes and knowledge. 4 subscales containing 45 items altogether measure what a person states he or she is willing to do regarding ecology and pollution issues (Verbal Commitment), what a person actually does do (Actual Commitment), how he or she feels about such issues (Affect), and what relevant knowledge he or she has (Knowledge). Data from Sierra Club, college, and non-college Ss suggest that the revised ecology scale, which takes less than 10 min to complete, clearly distinguishes persons of high concern and commitment to ecological issues. Data on validity (criterion groups) and reliability (split-half comparisons and homogeneity ratio) are presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
