Objective: To examine the role of intent and other theory of planned behavior (TPB) constructs in predicting college students' willingness to text while driving (TWD). Methods: This was a cross-sectional study. 243 male and female college students enrolled in the 2013–2014 academic year in the College of Health, Human Services & Nursing completed a survey on TWD. Inclusion criteria: All races and ethnicities, ≥18 years of age, cell phone owner, and licensed driver. Results: Over 70% of the sample (n = 243) reported talking on a cell phone and sending and receiving text messages “at least a few times” while driving within the past week. However, only 27% reported being stopped by police. Of these, 22% reported being fined. Within the past 30 days, 26% reported reading or sending TWD and having to slam on the brakes to avoid hitting another car or pedestrian(s) as a result. In all, 47% of the variance in intention to send TWD was accounted for by the full TPB model. Intention, in turn, predicted willingness to TWD. Intention also mediated the relationship between perceived behavioral control and willingness to TWD. Conclusion: Attitude was found to be the strongest predictor of intention. In addition, intention was found to mediate the relationship of willingness to TWD on perceived behavioral control. These findings highlight potential factors that could be targeted in behavioral change interventions seeking to prevent TWD.

This study applied a well-known, recently revised theoretical model of healthcare access and utilization, the Behavioral Model for Vulnerable Populations, to examine the relationship between access to care and utilization of eye care services among a multiethnic, predominately minority sample of residents from low-income public housing. Population-based, cross-sectional survey of community sample. Urban Public Housing Communities in Los Angeles County, California. A geographically defined stratified random sample of 152 residents (86% Latino or African American) 40 years of age and older from three urban public housing communities. Only 62% of our sample of persons 40 years and older had received an eye examination within the past 2 years. Sixty-one percent of participants reported having vision care coverage. Yet, one out of four respondents claimed that no health care provider had ever told them that they needed an eye-examination. Applying multiple logistic regression and controlling for a number of predisposing, enabling, and need-for-care characteristics, the variables 1) receiving advice from health care providers for eye examination (OR = 3.9, p < 0.01), 2) possessing coverage for eye-care (OR = 3.2, p < 0.01), and 3) having regular and continuity of medical care (OR = 2.4, p < 0.01) remained significant predictors of eye-examination within the past 2 years. This study documents significantly diminished utilization of eye care services relative to recommended guidelines for a low-income, predominately minority sample of residents from public housing communities. We documented no association between presence of diabetes or hypertension and recency of eye examination. Affordability, continuity, and regular sources of care, as well as receiving physician advice, remain the core factors significantly associated with receiving vision care. These results underscore the need for continued efforts to ensure that the medically underserved minority have access to vision care services. These findings also point toward the urgent need for educational and motivational interventions that encourage health care providers serving underserved communities to promote eye examination, particularly among diabetic patients, hypertensive patients, and other individuals at risk for eye-related disease and complications.

The term "intimate partner violence" (IPV) encompasses physical, sexual and psychological violence, or any combination of these acts, and globally is the most common type of violence against women. This study aims to examine the lifetime prevalence of different types of intimate partner violence (IPV) among Malawi women ages 15 to 49, and its association with age, education, and living in rural versus urban areas. Data was obtained from a cross-sectional study of data as part of the 2004 Malawi Demographic and Health Survey. Women were eligible for the study if they met the following criteria: 1) lived in one of the 15,041 households randomly selected from 522 rural and urban clusters located in 10 large districts of Malawi; 2) were married or cohabitating; and 3) were between the ages of 15 and 49 years. Consenting, eligible women responded to a comprehensive questionnaire covering demographic factors, health issues, as well as items related to physical, emotional and sexual IPV. To assess bivariate associations, chi-squared tests and multivariate logistic regressions were conducted. Among the 8291 respondents, 13% reported emotional violence; 20% reported being pushed, shaken, slapped or punched; 3% reported experiencing severe violence, such as being strangled or burned, threatened with a knife, gun or with another weapon; and 13% reported sexual violence. Data showed women ages 15 to 19 were significantly less likely to report emotional IPV, women ages 25 to 29 were significantly more likely to report being pushed or shaken, slapped or punched (OR 1.35; CI: 1.05-1.73), and women ages 30 to 34 were significantly more likely to report sexual IPV, compared to women ages 45 to 49 (OR 1.40; CI: 1.03-1.90). Finally, women who had no ability to read were less likely to report sexual IPV than their counterparts who could read a full sentence (OR 0.76; CI: 0.66-0.87). The prevalence of different types of IPV in Malawi appears slightly lower than that reported for other countries in sub-Saharan Africa. Further studies are needed to assess the attitudes and behaviors of Malawi women towards acceptability and justification of IPV as well as their willingness to disclose it.

As limited research exists on medical students' substance use patterns, including over-consumption of alcohol, the objective of this study was to determine prevalence and correlates of at-risk drinking among a national sample of medical students, using a cross-sectional, anonymous, Web-based survey. A total of 2710 medical students from 36 U.S. medical schools (1st to 4th year) completed the survey. Included in the instruments was a 10-item scale (AUDIT) to assess at-risk drinking behaviors within the last 12 months. Over 15% of the subjects (n = 412) scored positive for at-risk drinking (≥ 8). Multivariate analysis of the data revealed the following independent predictors were statistically significant (P ≤ 0.05) for at-risk drinking: being of younger age, male, unmarried, using illicit drugs, smoking tobacco products within the last 30 days, having low perception of risk, showing impulsive behavior, being depressed, and having gambling problems. Findings from this study provides initial data for investigating further associations between risky drinking behavior, lifestyle, and psychosocial factors, as well as effectiveness of curriculum or campus-wide policy interventions to reduce over-consumption of drinking among this population.
