| Abstract: | Although the relevance of single-case methodology for clinical research is stressed frequently in the literature, clinicians do seldom use this approach. The present contribution is an attempt to stimulate and exemplify the realization of single-case designs clinical settings. In the first part of this paper single-case designs and strategies of statistical analysis for practical use are discussed. In the second part three empirical studies are reported: (1) An A/B-design for evaluation of a relaxation program for treatment of chronic headache; (2) an A/B/A/B-design to analyze the effect of cognitive-behavioral treatment in anxiety; and (3) an A/B/C/B/C-desing to test psychological treatment in rehabilitation of a schizophrenic patient. |
