摘要：

Aim: A broad range of self-tests (testing for e.g. HIV, cancer, hepatitis B/C) is available on the Internet and can be conducted by lay consumers without the help of a health professional. However, little is known about the determinants of self-testing. The aims of this study were to investigate whether the use of self-tests can be predicted by (1) factors specified in social-cognitive health behaviour theories; (2) technological affinity; or (3) anticipated affect. Subjects and methods: An online survey was conducted to investigate social-cognitive health concepts, technological affinity, and anticipated affect as predictors of self-testing. Participants were invited in batches, representative of the age and gender distribution in Germany, until similar numbers of completed cases of non-self-testers (n = 512) and self-testers (n = 505) were reached. Univariate and multiple hierarchical logistic regression analyses were carried out. Results: Self-testing was significantly associated with self-test-related self-efficacy, perceived severity, perceived susceptibility, and to some degree with outcome expectancy. Technological competence acted as a suppressor variable, tending to enhance the predictive value of self-test-related self-efficacy. Participants who anticipated a positive self-test-related affect were more likely to be self-testers than non-self-testers. Conclusions: Self-testing was predicted by the common health psychological constructs. However, including technological affinity and anticipated affect into the model significantly improved the predictive value of the use of self-tests. Given the current shortage of physicians, especially in rural areas, the need for, and actual use of self-tests could increase in Germany in the future. Thus, follow-up studies investigating the emotional consequences of self-testing are needed. © 2016, Springer-Verlag Berlin Heidelberg.
