Refusal rates for participation in geriatric research have been surprisingly high. This may be due in part to inherent difficulties with a written consent procedure. A simple, easily administered, standardized verbal consent procedure (VCP) for the institutionalized elderly was developed to address this problem. Of 114 patients eligible for enrollment in a study evaluating outcomes of group psychotherapy, 100 gave verbal consent. When written consent was requested, 60 signed immediately; 35, only after substantial coaxing. Five patients refused to sign a consent form, although verbally agreeing to participate. It is estimated that the number of study participants would have been reduced by 40% had written consent been required. The findings raise ethical and logistical issues pertaining to a verbal consent procedure.
