This retrospective study examines the effects of a change in policy in
the method of offering appointments for assessment to patients referr
ed to an out-patient psychotherapy service. It was anticipated that th
e new system would reduce the frequency of non-attendance (DNAs) at as
sessment interviews, increase the proportion of attenders judged suita
ble for psychotherapy and reduce the proportion of early dropouts amon
gst those commencing therapy. Results confirmed a reduction in DNAs, b
ut suitability for therapy was not enhanced, nor did the rate of early
dropouts diminish. With the new system, proportionately fewer referra
ls were assessed and fewer commenced therapy, suggesting that it has c
reated a barrier to use of the service.
