34 The Group Climate Instrument was found to be internally consistent, with alpha’s rang- ing between .642 and .882. The ICC’s for the group climate subscales and the total cli- mate scale ranged from .193 to .385. These results indicate that a considerate proportion of variance (roughly 19-39%) can be attributed to between-group differences (i.e., the group level). Means, standard deviations, ICC’s, and results of reliability coefficients in terms of Cronbach’s alpha (α) and Guttman’s Lambda-2 (λ-2) are displayed in table 3. .681** .542** .356** .498** .882 .786 .642 .762 .918 .884 .795 .662 .770 .922 Support Growth Repression Atmosphere Overall climate Subscale Support α λ-2 Subscale Subscale Growth M Subscale Repression SD Subscale Atmos- phere ICC .584** .666** .407** .401** 3.668 3.809 2.883 3.283 3.556 -.361** -.248* -.339** -.293** 0.815 0.971 0.727 0.808 0.754 .513** .450** .477** .663** .279 .300 .193 .340 .385 Report mark ‘The support you receive from so- ciotherapists’ Report mark ‘What you learn here’ Report mark ‘The rules at the ward’ Report mark ‘The atmosphere at the ward’ Note. **p < .01.
