Value of HoNOS in assessing patient change in NHS psychotherapy and psychological treatment services

摘要

Background Little research on the value of Health of the Nation Outcome Scales (HoNOS) has occurred in out-patient settings, particularly psychotherapy services. Aims To determine whether HoNOS provides an adequate assessment for psychotherapy services which is sensitive to change. Methods HoNOS ratings from 1688 patients from eight out-patient psychotherapy services were collected. Of these, 362 also had ratings post-treatment. Mean scores, pre-to post-treatment differences, and reliable and clinically significant change criteria were calculated for HoNOS items and for total scores. Results The mean total HoNOS rating was 8.93, which is comparable to psychiatric out-patients. Only three items showed sufficient variability to use in assessing pre- to post-treatment change. Conclusions Significant limitations were found in rating items that commonly present to psychotherapists. The lack of variability in most items limits HoNOS's usefulness in this population.
