The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.
