Identifying the Physical Activity Needs of Outpatients with a Traumatic Brain Injury
Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment – emphasizing the need for effective rehabilitation programs. One mode of rehabilitation that has been demonstrated to improve health and reduce healthcare costs is health promotion programs (HPPs) that incorporate physical activity (PA). However, PA is not currently incorporated into the standard of care post-TBI. The purpose of this study was to conduct group interviews among individuals with a TBI undergoing outpatient rehabilitation to determine PA knowledge, attitudes, intentions, and barriers. Results will be used to develop a HPP that focuses on facilitating PA participation as part of the rehabilitation process. Seventeen participants completed a series of group interviews (2-3 people/group) regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through triangulation of data (i.e., theoretical underpinning; multiple researchers and data-coders). A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (1) an inability to differentiate between PA and physical therapy, (2) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (3) an interest in participating in a PA HPP as part of their rehabilitation. HPPs for outpatients with a TBI should educate individuals about PA, the associated health benefits, and the role PA plays in the rehabilitation process. A well designed HPP may increase the likelihood that individuals adopt and maintain PA as part of the rehabilitation process, thus reducing the risk of morbidity and mortality.
The Influence of Self-Esteem and Body Dissatisfaction on Muscle Dysmorphia and Exercise Dependence
Using the psycho-behavioral model as a conceptual framework, the purpose of this study was to explore the relationships between self-esteem, body dissatisfaction, muscle dysmorphia, and exercise dependence among college men. Participants (n = 110) completed surveys including a demographic questionnaire, the Rosenberg Self-Esteem Scale, Body Part Satisfaction Scale, Drive for Muscularity Scale, and Exercise Dependence Scale-21. No significant relationship was found between self-esteem and muscle dysmorphia. A significant correlation was found between body dissatisfaction and muscle dysmorphia, as well as between muscle dysmorphia and exercise dependence. These results partially support the psycho-behavioral model of muscle dysmorphia.
Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions
The FITNESSGRAM® is regularly used to assess physical fitness (PF) of adolescents. In addition to the PF assessment, the FITNESSGRAM also includes self-report physical activity (PA) items. The purpose of this study was to examine whether the self-report aerobic, muscular strengthening, and flexibility PA behavior items indicated adolescents’ cardiorespiratory, muscular strength, and flexibility fitness and their body composition. Logistic regression analysis was used to examine the relation between the amount of PA and PF status. Adolescents not meeting the recommended PA amount had significantly higher odds of not achieving a healthy fitness status. Meeting the recommended PA amount was associated with achieving healthy PF status. Thus, adolescents’ amounts of aerobic, muscular strengthening, and flexibility PA were an indication of their corresponding health-related PF standard.
Reliability and Validity of the FITNESSGRAM® Physical Activity Items
Large-scale assessments of children and youth physical activity (PA) behaviors are regularly conducted in school settings. In addition to assessing actual fitness, the FITNESSGRAM® assesses self-reported PA behaviors for aerobic, strengthening, and flexibility activity within the past 7 days. The purpose of this study was to examine the reliability and validity of the three PA items. Participants included 1010 students in grades three through twelve and were either tested under a teacher – teacher condition, an expert - expert condition, a teacher – expert condition, or a trained teacher – expert condition. Comparisons of the responses to the PA items indicated adequate reliability for teachers, but the reliability improved with training. Likewise, the validities for teachers are moderate to fair; however, they improved when teachers received additional training.
