Optimum split-half reliabilities for the Rorschach: projective techniques are more reliable than we think.

J Pers Assess . 1986;50 (1) :107-12

Résumé

A new technique for optimizing split-half reliability estimates yielded substantial and comparable increases in indexes of internal reliability for some major Rorschach variables across two diverse samples. Practical suggestions for applying this method to other projective tests were advanced. The inadvisability of computing odd-even reliability coefficients without regard to split-half distributional anomalies is addressed.
