title: [Effectiveness of validation. A literature study].
abstract: This review-article reports on literature on the effectiveness of validation; and approach used for disoriented elderly. Literature has been searched for by means of several (computerized) indexes and references. By contacting Feil, who developed validation, unpublished articles and reports became available. This search resulted in 13 effect-studies, of which 7 are unpublished, 2 descriptive reports, and 1 research-proposal. The effect-studies have varying designs with different methodological restrictions causing bias. The analysis showed that the quality and therefore the evidential value of the effect-studies is limited. The better the study, the less validation appeared to be effective. It is concluded that the hypothesis, that validation has positive effects on disoriented elderly and their caregivers, has no or minimal scientific basis. Before validation is implemented more and more in Dutch health care, scientific research addressing its effects is indicated.
