Slovak adaptation of CORE-OM (Clinical Outcomes in Routine Evaluation - Outcome Measure)

Abstract:

CORE-OM (Clinical Outcomes in Routine Evaluation - Outcome Measure) is a widely used self-rating measure, developed specifically for measuring outcome of psychological/psychiatric treatment. The process of its adaptation for the use in Slovak context is described in three studies. Study I. presents internal consistency coefficients of the Slovak version of CORE-OM, an assessment of the construct validity of the instrument as well as the comparison of clinical and non-clinical samples. In Study II., where we used a revised Slovak translation of CORE-OM, we are presenting the descriptive data of clinical and non-clinical samples, the test-retest reliability and the criteria of the statistically and clinically significant change. Study III describes a process of establishing the final version of the Slovak CORE-OM in collaboration with one of the authors of the original version. The Slovak version of CORE-OM has good psychometric properties, is highly internally consistent, and has sufficient test-retest reliability. It discriminates well between clinical and non-clinical samples. The criterion of statistical significant change (reliable change index - RCI) for all items of CORE-OM is 0,57. The cut-off score is 1,05 for males and 1,12 for females respectively. The Slovak version of CORE-OM is ready to be used widely in clinical practice; further research on its properties is being conducted.
