Abstract
BACKGROUND: With interest in personalised health care growing, so is interest in personal genetic testing. This is now offered direct-to-consumer, thereby referred to as direct-to-consumer genetic testing (DTC-GT). Criticisms have been expressed on whether a truly informed decision to undergo testing is made with regard to these services. In order to provide relevant information to achieve this, knowing the characteristics of the expected user population is helpful. Therefore, the aim of this study is to identify characteristics of individuals who (1) find the concept of DTC-GT acceptable and (2) consider undergoing DTC-GT in the distant or near future. METHODS: This cross-sectional study investigated factors associated with acceptability, consideration and intention in the Dutch general population. Studied variables included awareness, principles and how-to knowledge, attitude, innovativeness, and multiple demographic characteristics. Generalised linear models were applied to identify associated variables. RESULTS: Full data was obtained for 836 respondents. Of those, 18.3% found DTC-GT somewhat or totally acceptable, whereas 12.6% considered and 5.5% intended to undergo DTC-GT in the distant or near future. Acceptability was greater with lower principles knowledge, and consideration and intention with lower how-to knowledge. A more positive attitude and greater innovativeness were associated with an increase in all 3 outcomes. CONCLUSION: Informed decision making may be hampered as individuals with lower how-to knowledge were found to be more interested in pursuing testing. The identified characteristics can be used in development and distribution of public and personalized information, in order to help consumers make a truly informed decision.
