Development and Validation of an Instrument Measuring Determinants of Bystander Intervention to Prevent Sexual Assault: An application of the Reasoned Action Approach

Bystander Intervention (BI) is an evidence-based approach that is considered the gold standard by governmental organizations to reduce sexual assault in college. Few survey instruments are available to measure the predispositions students have towards engaging in BI. Valid and reliable instruments are greatly needed, especially those tailored to BI. The purpose of this study was to develop and validate an instrument based on the reasoned action approach with college students at two U.S. universities. An elicitation of beliefs was accomplished to inform survey items (i.e., behavioral, normative, and control beliefs). Then, an initial draft was developed and sent to an expert panel to establish validity. The final instrument was administered to undergraduate students (n = 291), and further psychometric properties (construct validity and internal consistency reliability) were evaluated. Data were fit into two separate models to evaluate fit. In the first model, a four-factor solution was evaluated (intentions, attitudes, perceived norms, and perceived behavioral control), and while results were modest, the second seven-factor solution model contained a better fit (intentions, instrumental and experiential attitudes, injunctive and descriptive norms, capacity, and autonomy). Researchers and practitioners examining BI in college can use this instrument to measure theory-based determinants of BI to reduce sexual assault

Examination of the Relationship of Dairy Product Consumption and Dietary Calcium with Body Mass Index Percentile in Children

Aim: The purpose of this study was to assess the relationships of dairy product and calcium intake with BMI percentile in children. Methods: In this cross-sectional analysis, the relationships of dairy product (cup equivalents/day) and dietary calcium (mg/day) (measured by 24 hour recall) consumption with BMI percentile [derived from Centers for Disease Control and Prevention (CDC) sex-specific BMI-for-age growth charts] were assessed in 101 healthy U.S. children (ages 8-13). Results: Subject characteristics included (mean + SD): dairy product consumption (2.8 + 1.4 cup equivalents/day), dietary calcium (1039.4 + 431.4 mg/day), and BMI percentile (70.1 + 29.7). Dairy product intake and dietary calcium were inversely related to BMI percentile (p= 0.005). In subjects <85th BMI percentile (n= 50 normal weight and n= 3 underweight), there was an inverse association of dairy product intake with BMI percentile (p= 0.001) and calcium intake with BMI percentile (p< 0.001). However, no association of dairy product consumption or calcium intake with BMI percentile was observed in overweight (85th percentile ≤ BMI < 95th percentile, n= 19) or obese subjects (BMI > 95th percentile, n= 29). Removal of underweight subjects from the analysis only minimally impacted the results. Differences in dietary intake (MyPyramid food groups, calories, macronutrients, micronutrients) among normal, overweight, and obese subgroups were examined. No significant differences were detected between groups, and removing underweight subjects did not change the findings. Conclusions: These results provide the basis for further investigation into a potential role of dairy and calcium in achieving a healthy body weight in children

The Effect of an 8-Week Tai Chi Exercise Program on Physical Functional Performance in Middle-Aged Women

The purpose of this study was to determine the effectiveness of an 8-week Tai Chi Chih exercise program on physical functional performance (PFP) among women aged 45 to 65 years. A quasi-experimental design with a nonequivalent comparison group was used. Forty-one healthy inactive women were assigned to either an intervention group (n = 19) or a comparison group (n = 19). A 60-min Tai Chi Chih exercise class was conducted twice a week for 8 weeks. PFP was measured at baseline and postintervention using the Continuous Scale Physical Functional Performance–10 (CS-PFP 10). Between-group differences were analyzed using one-way analysis of covariance (ANCOVA). After participating in the 8-week program, intervention group participants showed greater improvement in the CS-PFP measures (p .06). However, the comparison group had little changes. The findings from this study suggest that participation in an 8-week Tai Chi Chih exercise program can improve PFP in healthy, community-dwelling middle-aged women.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
