Influence of Patient Characteristics and Psychological Needs on Diabetes Mobile App Usability in Adults With Type 1 or Type 2 Diabetes: Crossover Randomized Trial.

Background: More than 1100 diabetes mobile apps are available, but app usage by patients is low. App usability may be influenced by patient factors such as age, sex, and psychological needs.

Objective: Guided by Self-Determination Theory, the purposes of this study were to (1) assess the effect of patient characteristics on app usability, and (2) determine whether patient characteristics and psychological needs (competence, autonomy, and connectivity)-important for motivation in diabetes care-are associated with app usability.

An updated protocol to detect invalid entries in an online survey of men who have sex with men (MSM): how do valid and invalid submissions compare?

Researchers use protocols to screen for suspicious survey submissions in online studies. We evaluated how well a de-duplication and cross-validation process detected invalid entries. Data were from the Sexually Explicit Media Study, an Internet-based HIV prevention survey of men who have sex with men.

Radiology diagnostic exchange agents: clinical term identification and validation.

Diagnostic radiology is one of the key areas of clinical diagnosis on which much of the health care system is built. Along with pathology, radiology has a unique role in providing diagnostic information for prognosis, treatment, and management of clinical conditions. This role is clinically challenging due to the problems of knowledge management associated with the free-text radiology reports which are currently the standard of practice for radiology care.

Reducing HIV risk behavior of men who have sex with men through persuasive computing: results of the Men's INTernet Study-II.

Objective: The primary objective of this study was to develop and test a highly interactive Internet-based HIV prevention intervention for men who have sex with men (MSM). MSM remain the group at highest risk for HIV/AIDS in the United States and similar countries. As the Internet becomes popular for seeking sex, online interventions to reduce sexual risk are critical.

The Challenges of Ensuring Participant Consent in Internet-based Sex Studies: A Case Study of the Men's INTernet Sex (MINTS-I and II) Studies.

This study documents our experience in designing, testing, and refining human subjects' consent protocol in 3 of the first NIH-funded online studies of HIV/STI sexual risk behavior in the USA. We considered 4 challenges primary: a) designing recruitment and enrollment procedures to ensure adequate attention to subject considerations; b) obtaining and documenting subjects' consent; c) establishing investigator credibility through investigator-participant interactions; d) enhancing confidentiality during all aspects of the study. Human consent in online studies appears more relative, continuous, inherent, tenuous, and diverse than in offline studies.

HIV risk and the internet: results of the Men's INTernet Sex (MINTS) Study.

This study assessed the feasibility of online recruitment of high-risk Latino men who have sex with men (MSM) for HIV prevention survey research and investigated the relationship between Internet use and unsafe sex. Participants (N = 1,026) were Internet-using Latino MSM living in the U.S.

Conducting Internet-based HIV/STD prevention survey research: considerations in design and evaluation.

The aim of this paper is to advance rigorous Internet-based HIV/STD Prevention quantitative research by providing guidance to fellow researchers, faculty supervising graduates, human subjects' committees, and review groups about some of the most common and challenging questions about Internet-based HIV prevention quantitative research. The authors represent several research groups who have gained experience conducting some of the first Internet-based HIV/STD prevention quantitative surveys in the US and elsewhere. Sixteen questions specific to Internet-based HIV prevention survey research are identified.

Characteristics of latino men who have sex with men on the internet who complete and drop out of an internet-based sexual behavior survey.

To identify biases and threats to validity of Internet survey data collection on HIV-related risk behaviors, we studied 1,546 Latino men who have sex with men on the Internet recruited through banner impressions on a leading national gay Internet site. The study could be completed in English or Spanish. Of those commencing, 33.
