This study aims to test the third-person effect (TPE) in the perception of Internet privacy risks. Support was found for a TPE model suggesting that users report greater perceived Internet privacy risks on others than on themselves, based on a sample ( N = 613) from Amazon MTurk. In particular, the differential perception of Internet privacy risks between self and others increased people's willingness to recommend protective measures to others but decreased their willingness to adopt protective measures themselves. Moreover, social distance, perceived Internet privacy knowledge, negative online privacy experiences, and Internet use activities emerged as significant predictors of TPE perceptions about Internet privacy risks. Study findings indicated that third-person perception is one of the major barriers inhibiting the adoption of privacy protection measures. The antecedents of TPE perceptions detected here provide valuable implications about how to enable Internet users to protect their privacy security.

With a general basis in protection motivation theory, this study builds a three-stage model from online negative privacy experiences to online privacy protection motivation to online privacy protection behaviors. With 2013 survey data ( N = 528), a well-fitting structural equation model was tested, indicating general support for the model's progression. There was support in only one instance, however, for the mediation role of online privacy protection motivation. In that case, awareness of online information disclosure mediated the effects of information stolen on contact management. The other protection motivation—online privacy concerns—had stronger effects on the four online privacy protection behaviors.

Purpose: The current study aims to explore the barriers for middle-aged Chinese to learn about and uptake low-dose computed tomography (LDCT) lung cancer screening. Methods: Data were collected via an online survey in December 2019. Final valid sample included 640 respondents, aged 40–60 years old, from 21 provinces of China. We performed multiple linear regressions to test the potential barriers to LDCT scan. Findings: Cost concerns, distrust in doctors, fears of disease, lack of knowledge, and optimistic bias are negatively associated with the intention to learn about and uptake LDCT scan. Implications: Our study contributes to understanding the negative predictors of middle-aged Chinese to get LDCT lung cancer scans. Future campaign programs should help audiences to build comprehensive understandings about lung cancer and LDCT scan. To better promote LDCT scan in China, the government should fund more trial programs continuously and public efforts should be made to rebuild the patient–doctor trust.
