This information Drop-out or Lost to Follow-up may consist of health service contacts kept on health care databases such as case notes as Two main issues affect the inferences about the well as information from third parties. The first is the effect of those people involving people with severe disorders, third- who drop out of the therapy and the second party information from key workers is nearly is those people who are lost to contact at any always included as part of the measurement of stage of the trial. Some systems the relevance and benefit of the trial results to the assume that the person would not have changed wider community. It may therefore be unethical at all since leaving the trial (LOCF), but this not to collect as much of it as possible. Drop-outs may be those people who the idiosyncratic interpretations made by local COGNITIVE BEHAVIOUR THERAPY 285 Research Ethics committees will lead to further ways. Recruitment may be affected by what ser- confusion in this already complicated area.

This biased towards certain subgroups who may, for distinction is useful in clarifying what is being whatever reasons, have no access to private care.
