Studies examining factors that influence credibility perceptions have demonstrated the importance of a source’s gender and attractiveness. However, scholars have only begun to extend these findings to credibility in the context of mediated sports. This experiment tested the relationship that gender and attractiveness have with credibility and whether this varies as a function of the gender of the athlete in a given story. Results indicate that reporters’ gender and attractiveness and athlete gender affect perceptions of credibility such that when reporters are of the opposite gender of an athlete, they are perceived as most credible when they are less attractive. Results also reveal a gender bias such that reporters are perceived as most credible when covering male athletes, regardless of reporter gender. Explanations are offered for these findings, in addition to a discussion of the implications for news practitioners.

The purpose of this study was to explore Native American students’ participation patterns and self-reported physical activities. Participants (N = 376) completed the previously validated Physical Activity Questionnaire (PAQ) a four part 83-item recall questionnaire from the NIH Pathways Study. Data analyses included internal consistency reliability, descriptive statistics and Kappa tests investigating stability over reporting time periods. Similar to urban students’ reports, these Native American students reported frequent participation in only a few types of physical activities along with common reports of sedentary behaviors. While this study adds to our knowledge of Native American students’ physical activity preferences and activity patterns, more information is needed to aid development of specific, culturally relevant physical activity programming.

options and challenges ( Warren et al., 2010 ). Subjective (i.e., self-reported) PA measures are commonly employed in population and intervention studies as they are easy to use and cost less than objective (i.e., device-based) assessment. Wearable device-based technologies, such as accelerometers, have

Background:

Self-report measures have been validated and are widely used. Interest currently lies in the development of simple, valid methods that can be used in any location to determine level of PA in large populations/samples. The purpose of this report is to illustrate tracking of physical activity behaviors and musculoskeletal injury reports on a weekly basis via the Internet.

Methods:

The Women’s Injury Study (WIN) methodology includes use of BRFSS-related physical activity items that are completed online by more than 900 women weekly for an average of 3 years.

Results:

With more than 45,000 weekly physical activity and injury logs, the percentage of total logs submitted via online records is 91%. Self-reported pedometer steps are consistent with similar, smaller research samples.

Conclusions:

This report suggests that Internet tracking is a viable means of assessing nearly real-time physical activity, describes the process of developing and monitoring self-reported physical activity behaviors via the Internet, and provides recommendations for others considering such methods.

Context:

Advances in device-based measures have led researchers to question the value of reported measures of physical activity or sedentary behavior. The premise of the Workshop on Measurement of Active and Sedentary Behaviors: Closing the Gaps in Self-Report Methods, held in July 2010, was that assessment of behavior by self-report is a valuable approach.

Objective:

To provide suggestions to optimize the value of reported physical activity and sedentary behavior, we 1) discuss the constructs that devices and reports of behavior can measure, 2) develop a framework to help guide decision-making about the best approach to physical activity and sedentary behavior assessment in a given situation, and 3) address the potential for combining reported behavior methods with device-based monitoring to enhance both approaches.

Process:

After participation in a workshop breakout session, coauthors summarized the ideas presented and reached consensus on the material presented here.

Conclusions:

To select appropriate physical activity assessment methods and correctly interpret the measures obtained, researchers should carefully consider the purpose for assessment, physical activity constructs of interest, characteristics of the population and measurement tool, and the theoretical link between the exposure and outcome of interest.
