| Abstract: | We tested the Door-in-the-Face technique (DITF) on blood donation with a delay between the acceptance of the request and the real possibility of complying with it. University students were solicited to give blood during a special one-day drive. After the refusal to participate in a long-term donor program, participants were asked for a one unit blood donation. In the control condition, only the latter request was addressed. The participants were either solicited two or three hours before the blood drive (delay) or during the blood drive (no delay). Results showed the DITF technique to be associated with greater verbal compliance with the request. However, the DITF technique with no delay was associated with greater behavioral compliance than were both of the control conditions and the DITF with a delay condition. |
