Criterion validity of the rorschach mutuality of autonomy (MOA) scale: A meta-analytic review

The present study consisted of a meta-analytic review of the criterion validity of the Rorschach Mutuality of Autonomy (Urist, 1977) scale. Search procedures yielded 27 independent samples (total N = 1,803, average n = 67, SD = 31) for inclusion in the meta-analysis. Results support the criterion validity of the Mutuality of Autonomy with an average overall weighted effect size of r = .24, p < .001 (95% confidence interval = .18, .29). Publication bias analyses indicate the possibility for bias and demonstrate that the likely impact of any such bias would bring the average overall weighted effect size down to r = .18, p < .001 (95% confidence interval for adjusted effect size = .11, .24). The data were not demonstrably heterogeneous (Q = 37.67, df = 26, p = .07), and all between-study moderator analyses were nonsignificant (ps > .19) with the exception of the specific type of criterion variable. Implications for future research and clinical practice are discussed.
