Predicting facebook users online privacy protection: Risk, trust, norm focus theory, and the theory of planned behavior

Journal ArticleThis is an Accepted Manuscript of an article published by Taylor & Francis in The Journal of Social Psychology on 21 April 2014, available online: http://wwww.tandfonline.com/10.1080/00224545.2014.914881The present research adopts an extended theory of the planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N = 119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implicit perceived risk, trust of other Facebook users, and intentions toward protecting their privacy online. Behavior was measured indirectly 2 weeks after the study. The data show partial support for the theory of planned behavior and strong support for the independence of subjective injunctive and descriptive norms. Risk also uniquely predicted intentions over and above the theory of planned behavior, but there were no unique effects of trust on intentions, nor of risk or trust on behavior. Implications are discussed. © Copyright © Taylor & Francis Group, LLC

Healthy eating: A beneficial role for perceived norm conflict?

ArticleThis is the author accepted manuscript. The final version is available from Wiley via the DOI in this record.Normative influence on dietary decision making was assessed as a function of the referent informational influence model within an extended theory of planned behavior framework. In a longitudinal design, university students (N = 141) completed measures of attitudes, perceived behavioral control, subjective norms, referent group norms, and intentions toward healthy eating, with healthy eating behavior reported 2 weeks later (n = 82). A distinction was made between injunctive and descriptive norms, in line with norm focus theory. The extended theory of planned behavior and referent informational influence models were partially supported. An interaction between group injunctive and descriptive norms emerged such that misaligned group norms were associated with healthier eating behavior than aligned group norms (both supportive and unsupportive). Theoretical and applied implications are discussed

Human immunodeficiency virus continuum of care in 11 european union countries at the end of 2016 overall and by key population: Have we made progress?

Background. High uptake of antiretroviral treatment (ART) is essential to reduce human immunodeficiency virus (HIV) transmission and related mortality; however, gaps in care exist. We aimed to construct the continuum of HIV care (CoC) in 2016 in 11 European Union (EU) countries, overall and by key population and sex. To estimate progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 target, we compared 2016 to 2013 estimates for the same countries, representing 73% of the population in the region. Methods. A CoC with the following 4 stages was constructed: number of people living with HIV (PLHIV); proportion of PLHIV diagnosed; proportion of those diagnosed who ever initiated ART; and proportion of those ever treated who achieved viral suppression at their last visit. Results. We estimated that 87% of PLHIV were diagnosed; 92% of those diagnosed had ever initiated ART; and 91% of those ever on ART, or 73% of all PLHIV, were virally suppressed. Corresponding figures for men having sex with men were: 86%, 93%, 93%, 74%; for people who inject drugs: 94%, 88%, 85%, 70%; and for heterosexuals: 86%, 92%, 91%, 72%. The proportion suppressed of all PLHIV ranged from 59% to 86% across countries. Conclusions. The EU is close to the 90-90-90 target and achieved the UNAIDS target of 73% of all PLHIV virally suppressed, significant progress since 2013 when 60% of all PLHIV were virally suppressed. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control
