The negative as potential prognostic marker of outcome in psychotherapy.

From 73 patients, 10 with the best, and 10 with the worst outcomes after psychotherapy were compared statistically for the frequency of 'not' and 'never' at commencement of psychotherapy, and for change in their frequency after therapy. A highly statistically significantly difference was found at commencement of psychotherapy in that the negative was used more frequently by the worst outcome group (p=.006). No significant differences were found for change in frequency after therapy. Thus, the frequent use of the negative at commencement of psychotherapy seems to predict a poor outcome.
