Input: Three studies were identified that met the inclusion criteria (Peoples 1982; Robb 1986; Toseland 1997) incorporating data on a total of 116 patients (42 in experimental groups, and 74 in the control groups (usual care 43 and social contact 21, 10 in reality orientation). It was not possible to pool the data from the 3 included studies, either because of the different lengths of treatment or choice of different control treatments, or because the outcome measures were not comparable. Two significant results were found:  Peoples 1982 - Validation versus usual care. Behaviour at 6 weeks [MD --5.97, 95% CI (-9.43 to -2.51) P=0.0007, completers analysis] favours validation therapy.  Toseland 1997 - Validation versus social contact. Depression at 12 months (MOSES) [MD -4.01, 95% CI (-7.74 to - 0.28) P=0.04, completers analysis] favours validation. There were no statistically significant differences between validation and social contact or between validation and usual therapy. There were no assessments of carers. There is insufficient evidence from randomised trials to allow any conclusion about the efficacy of validation therapy for people with dementia or cognitive impairment.
Output:

Three studies were identified that met the inclusion criteria. It was not possible to pool the data from the 3 included studies, either because of the different lengths of treatment or choice of different control treatments, or because the outcome measures were not comparable. Two significant results were found but there were no statistically significant differences between validation and social contact or between validation and usual therapy. There were no assessments of carers. All in all there is insufficient evidence from randomised trials to allow any conclusion about the efficacy of validation therapy for people with dementia or cognitive impairment.
