This article investigated using the eB4CAST dissemination tool to communicate impact from a campus-based obesity prevention program. Data from Get Fruved RCT university sites collected at baseline were used to generate eB4CAST reports. Experts (n = 13) and RCT sites (n = 15) were asked to provide feedback on eB4CAST reports based on appeal, understanding, and clarity. On all Likert items, participants rated above 7 on each (out of 10). Positive responses from open-ended questions included eB4CAST reports being clear, visually appealing, and aid in program understanding. Overall, eB4CAST was successful in relaying data and information for the Get Fruved program, thus a means for science communication that could be used in interventions. Utilizing infographics to report data and information is a feasible way to disseminate and communicate in a cost-effective, timely manner.

Comparisons were made with mean intakes derived from up to 3 24-h recall interviews at baseline and follow-up (at 12 mo in 3 sites, 6 mo in the fourth). A social-desirability-related underestimate in fat intake on the PFat relative to the 24HR (percentage energy as fat) was evident in women [baseline b1⁄420.56 (P1⁄4 0.005); follow-up b1⁄420.62 (P , 0.001)]. There was an overestimate in FVS-derived fruit and vegetable consumption (servings/week) in men enrolled in any intervention at follow-up (b1⁄4 0.39, P1⁄4 0.05) vs. baseline (b1⁄4 0.04, P1⁄4 0.75). The 1-item fruit and vegetable question was associated with an overestimate at baseline in men according to SD score (b 1⁄4 0.14, P 1⁄4 0.02), especially men with less than college...

Thus, the overarching aim of this research was to develop a tool to measure patients' use of CBT skills, such that it would have clinical utility for patients and therapists during treatment. In Study 1, the authors developed an initial set of items for the Cognitive-Behavioral Therapy Skills Questionnaire (CBTSQ). They submitted these items to an exploratory factor analysis in an initial administration (n = 350) and to a confirmatory factor analysis in a second administration (n = 378). Results indicated that there were two factors (Behavioral Activation and Cognitive Restructuring) with good factor structure and internal consistency, and both the factors evidenced expected relationships with other constructs. In Study 2, the criterion validity of the CBTSQ was investigated on a patient sample in a CBToriented treatment setting. Results showed that CBTSQ scores increased following treatment, and Cognitive Restructuring and Behavioral Activation scores predicted reduction of overall psychiatric symptoms and depression. Behavior Modification 35(6) Thus, the CBTSQ appears to be a promising measure of CBT skill acquisition and treatment outcome as well as an instrument that can help patients and therapists monitor progress specifically related to a CBT skills training treatment approach.

Methodological differences may be responsible for variable results from eating rate (ER) studies.... more Methodological differences may be responsible for variable results from eating rate (ER) studies. It is unknown whether self-reported, lab-measured, and free-living ER's align. This study was the first to explore relationships among self-reported, laboratory-measured and free-living ER's. We investigated this relationship in 60 randomly selected male and female college students who were stratified by self-reported eating rate (SRER) (Slow, Medium, and Fast) from 1110 on-line survey respondents. Test day; subjects ate a prescribed breakfast (400 kcal) at home, recording meal duration (MD); 4 h later they individually ate an ad libitum laboratory pasta lunch at their own (natural) pace; remainder of the day they recorded free-living intake and MD. As expected the three self-reported ER categories aligned with lab ER (Fast = 83.9 ± 5.5, Medium = 63.1 ± 5.2, Slow = 53.0 ± 5.4 kcals/min). In all ER categories at all meals, men ate faster than women (Men = 80.6 ± 30.7 kcals/min: Women = 52.0 ± 21.6 kcals/ min). A difference in lab measured ER by SRER F = (2, 58) = 7.677, post hoc Tukey analysis found fast differed from medium and slow. The three free-living meal ER's did not align with self-report categories. Findings suggest various methods of measuring ER may yield differing results, at least in this population, but results support the use of SRER as a valid measure.

The contents of snack and beverage vending machines in 78 buildings on 11 US post-secondary education campuses were surveyed. Of the 2607 snack machine slots surveyed, the most common snacks vended were salty snacks (e.g., chips, pretzels) and sweets (i.e., candy and candy bars). The 1650 beverage machine slots assessed contained twice as many sugar-sweetened beverages as non-calorie-containing beverages. Only two institutions sold both milk and 100% juice in vending machines. The portion of snacks and beverages sold averaged more than 200 cal. Neither snacks nor beverages were nutrient dense. The majority of snacks were low in fiber and high in calories and fat and almost half were high in sugar. Most beverages were high in calories and sugar. This study's findings suggest that vending machines provide limited healthful choices. Findings from benchmark assessments of components of the food environment, like the vending options reported here, can provide valuable input to campus administrators, health services, food service, and students who want to establish campus policies to promote healthful eating.

Previous research has identified a relationship between emotional eating and weight gain in young adults, but outside the realm of eating disorders, few studies qualitatively capture why individuals cope with emotions by eating. Exploratory qualitative research was conducted, including 3-day food journals and indepth interviews, with proportionate quota sampling of eight male and eight female undergraduate students to gain an understanding of students' perceptions of their emotional eating behaviors. Participants were purposively selected based on their emotional eating scores on the Weight Related Eating Questionnaire from a larger survey assessing student eating behaviors. Participants' (n = 16) mean age was 19.6 ± 1.0 years and all self-reported their race to be white. Mean Body Mass Index (BMI) for females and males was 24.1 ± 1.2 kg/m 2 and 24.8 ± 1.7 kg/m 2 , respectively. Findings from the qualitative analyses indicated gender differences and similarities. Females identified stress as the primary trigger for emotional eating, frequently followed by guilt. Males were primarily triggered by unpleasant feelings such as boredom or anxiety turning to food as a distraction; however, males were less likely to experience guilt after an emotional eating episode than females. During emotional eating episodes, both genders chose what they defined as unhealthful foods. These findings indicate a multidisciplinary intervention focusing on emotion and stress management in addition to dietary behavior change should be developed to reduce the potential for weight gain associated with emotional eating in the college-aged population.

This study evaluated the policy and built and recreation environmental supports for physical activity on 13 university campuses. Design. Environmental audit survey. Setting. Thirteen U.S. universities, 2009. Subjects. University policies, recreation programs and facilities, and at least five additional buildings per campus. Measures. The Physical Activity Campus Environmental Supports Audit was developed for this study. Analysis. Analysis of variance with post hoc Tukey's B and v 2 assessed differences by institution and building type. Results. The mean obesogenic policy score was significantly lower than the desired score, 7 (p ¼ .002), with only one campus scoring 10. The mean built environment audit score (5.4 6 1.7) was low, with significant differences between institutions (p , .001) and only three campuses scoring above the desired score, 7. Although generally stairwells were clean and well lighted, there was a lack of signage to encourage stair use (p , .001). Overall, recreation programs (7.1 6 .7) and facilities (7.1 6 1.2) scored well, but amenities scores were lower for satellite (2.8 6 1.6) versus main (4.1 6 1.8) recreation facilities (p ¼ .04). Conclusion. On these 13 university campuses, recreation programs and facilities were supportive of healthful lifestyles for obesity prevention, but policies and the built environment were not. This physical activity environmental audit survey requires testing in a wider sample of postsecondary institutions to corroborate its utility and provide evidence to support initiatives to improve campus environments for physical activity.

Randomized, controlled trial using online questionnaires and on-site physical and fitness assessments with measurement intervals of 0 (baseline), 3 (postintervention), and 15 months (follow-up). Online intervention delivered to college students; a centralized Web site was used for recruitment, data collection, data management, and intervention delivery. College students (18-24 years old, n = 1689), from eight universities (Michigan State University, South Dakota State University, Syracuse University, The Pennsylvania State University, Tuskegee University, University of Rhode Island, University of Maine, and University of Wisconsin). A 10-lesson curriculum focusing on healthful eating and physical activity, stressing nondieting principles such as size acceptance and eating competence (software developer: Rainstorm, Inc, Orono, Maine). Measurements included anthropometrics, cardiorespiratory fitness, fruit/vegetable (FV) intake, eating competence, physical activity, and psychosocial stress. Repeated measures analysis of variance for outcome variables. Most subjects were white, undergraduate females (63%), with 25% either overweight or obese. Treatment group completion rate for the curriculum was 84%. Over 15 months, the treatment group had significantly higher FV intake (+.5 cups/d) and physical activity participation (+270 metabolic equivalent minutes per week) than controls. For both groups, anthropometric values and stress increased, and fitness levels decreased. Gender differences were present for most variables. First-year males and females gained more weight than participants in other school years. A 10-week online nutrition and physical activity intervention to encourage competence in making healthful food and eating decisions had a positive, lasting effect on FV intake and maintained baseline levels of physical activity in a population that otherwise experiences significant declines in these healthful behaviors.

Cross-sectional. Nine U.S. universities. Enrolled college students (N = 1252; 18-24 years; 80% white; 59% female). Survey included the Pittsburgh Sleep Quality Index (PSQI), Three-Factor Eating Questionnaire (TFEQ), Satter Eating Competence Inventory (ecSI), National Cancer Institute Fruit/Vegetable Screener, International Physical Activity Questionnaire, Work Time Pressure items, and sociodemographic characteristics. Chi-square and t-tests determined significant bivariate associations of sociodemographics, sleep behaviors, eating behaviors, physical activity behavior, and work time pressures with weight status (i.e., healthy vs. overweight/obese). Statistically significant bivariate associations with weight status were then entered into a multivariate logistic regression model that estimated associations with being overweight/obese. Sex (female), race (nonwhite), older age, higher Global PSQI score, lower ecSI total score, and higher TFEQ Emotional Eating Scale score were significantly (p < .05) associated with overweight/obesity in bivariate analyses. Multivariate logistic regression analysis showed that sex (female; odds ratio [OR] = 2.05, confidence interval [CI] = 1.54-2.74), older age (OR = 1.35, CI = 1.21-1.50), higher Global PSQI score (OR = 1.07, CI = 1.01-1.13), and lower ecSI score (OR = .96, CI = .94-.98), were significantly (p < .05) associated with overweight/obesity. Findings suggest that obesity prevention interventions for college students should include an education component to emphasize the importance of overall sleep quality and improving eating competence.

A 15-month (10-week intensive intervention with a 12-month follow-up) randomized, controlled trial delivered via Internet and e-mail. Thirteen college campuses. A total of 1,639 college students. Twenty-one mini-educational lessons and e-mail messages (called nudges) developed with the non-diet approach and focusing on eating behavior, physical activity, stress management, and healthy weight management. Nudges were short, frequent, entertaining, and stage-tailored to each behavior, and reinforced lesson content. All participants were assessed at baseline, postintervention (3 months from baseline), and follow-up (15 months from baseline) for primary outcomes of weight, body mass index (BMI), fruit and vegetable intake (FVI), physical activity (PA), and perceived stress; and secondary outcomes of waist circumference, percent dietary fat, energy from sugar-sweetened beverages, servings of whole grains, self-instruction and regulation for mealtime behavior, hours of sleep, and stage of readiness for change for consuming 5 cups of FVI, completing 150 minutes of PA/wk, and managing stress on most days of the week. Demographics were collected at baseline. Chi-square analysis and mixed-models repeated measures analysis were performed to determine differences between experimental and control outcomes. There were no differences between experimental and control participants in BMI, weight, and waist circumference. There were small improvements in FVI (P = .001), vigorous PA in females (P = .05), fat intake (P = .002), self-instruction (P = .001), and regulation (P = .004) for mealtime behavior, and hours of sleep (P = .05) at postintervention, but improvements were not maintained at follow-up. At postintervention, a greater proportion of experimental participants were in the action/maintenance stages for FVI (P = .019) and PA (P = .002) than control. Young Adults Eating and Active for Health is one of the first studies to use the community-based participatory research process of PRECEDE-PROCEED to develop a non-diet approach intervention. Although there were no differences between experimental and control participants in weight change or BMI, the intervention supported positive change in behaviors that may mediate excessive weight gain, such as increasing FVI and more healthful self-regulation mealtime behaviors immediately postintervention. Additional strategies to maintain the behavior changes need to be explored.

Most people experience weight regain following the termination of a weight management program. The failure to maintain changes in diet and exercise patterns is a major factor. This study presents 24-month outcomes of a healthy-lifestyle weight management program designed to promote long-term changes in diet and exercise behaviors.

Participants (N = 1,686) were 77% white, 62% female, aged 18-24 years (mean ± SD, 19.1 ± 1.1 years), and enrolled at 8 US universities. Body mass index (BMI) was calculated for self-report (via online survey); trained researchers measured height and weight and categorized them as normal (18.5 to < 25), overweight (25 to < 30), obese (30 to < 35), and morbidly obese (≥ 35). Concordance of self-report vs objectively measured BMI groups using chi-square revealed that 93% were accurate, 4% were underestimated, and 2.7% were overestimated. Pearson correlations and adjusted linear regression revealed significant associations between self-report and measured BMI (r = .97; P < .001) and BMI adjusted for age, gender, and race/ethnicity (R(2) = .94). Concordance was also high between BMI categories (kappa = 0.77; P < .001). Findings provide support for the utility of self-report height and weight for survey research in college students.

Weight management interventions for college-age men and women might be more effective if they were tailored to subgroups of students with similar behavioral and psychosocial characteristics associated with body weight status. The purpose of this study was to use cluster analysis to identify homogenous subgroups of college-aged men and women enrolled in a weight gain prevention study
