Investigating and Promoting the Decision towards Signing an Organ Donation Card


Using the Health Action Process Approach (HAPA) as a theoretical backdrop, the aim of this research, which consists of two studies, was to understand the process of goal setting and deciding to sign an organ donor card. In Study 1 (N = 550), we tested the HAPA’s stages in terms of discontinuity patterns in the variables predicting goal setting for organ donation. As expected, multigroup structural equation modeling revealed discontinuity patterns in terms of different prediction patterns. In Study 2 (N = 389), the efficacy of a planning intervention that aimed to foster the translation of goals into behavior was tested: participants who received the intervention were more likely to order a donor card than those who did not. Contrary to the HAPA’s predictions, within the intenders group the planning intervention did not stimulate behavior more frequently than in the control condition. In general, the stage-specific planning intervention is of practical importance, as it shows that brief and relatively inexpensive communication can enhance organ donation behavior.
