The purpose of this study was to examine the relationship between self-reported exercise behavior and physiological indicators of exercise behavior (body composition and oxygen consumption measures) in older women. Three self-report exercise behavior instruments were administered in counterbalanced order. Body mass index and sums of skinfold thicknesses were used as measures of body composition. Oxygen consumption was measured using a metabolic cart during a treadmill test while women walked at approximately 70% of their heart rate reserve. Fifty-nine women participated (68.7 ± 6.0 years). Results showed that self-reported exercise behavior was moderately related to body composition measures. However, predicted maximal oxygen consumption was only weakly related to self-reported exercise behavior.

Over the years, self-report measures of physical activity (PA) have been employed in applications for which their use was not supported by the validity evidence.
To address this concern this paper 1) provided an overview of the sources of validity evidence that can be assessed with self-report measures of PA, 2) discussed the validity evidence needed to support the use of self-report in certain applications, and 3) conducted a case review of the 7-day PA Recall (7-d PAR).
This paper discussed 5 sources of validity evidence, those based on: test content; response processes; behavioral stability; relations with other variables; and sensitivity to change. The evidence needed to use self-report measures of PA in epidemiological, surveillance, and intervention studies was presented. These concepts were applied to a case review of the 7-d PAR. The review highlighted the utility of the 7-d PAR to produce valid rankings. Initial support, albeit weaker, for using the 7-d PAR to detect relative change in PA behavior was found.
Overall, self-report measures can validly rank PA behavior but they cannot adequately quantify PA. There is a need to improve the accuracy of self-report measures of PA to provide unbiased estimates of PA.

Concussions are one of the most common sport-related injuries affecting athletes participating at all levels across a variety of sports. It has been reported that up to 3.8 million concussive events occur per year that are sports-related. One significant issue with identifying concussions is that a clinical diagnosis is based on the presence of signs and symptoms, which are self-reported by the patient. In the adolescent population, injury to the brain is possible with even the slightest insult, which can affect recovery and predispose them to subsequent concussions. Recent legislative efforts have included athlete education as a means to improve concussion reporting. More specifically, all 50 US states and the District of Columbia have implemented concussion legislation that includes some type of concussion education protocol, but there is still little evidence to suggest that enhanced knowledge levels result in behavior changes, including improved concussion-reporting practices. It is unclear what factors make an adolescent athlete more or less likely to report the symptoms of a concussion.
Focused Clinical Question:
What factors positively or negatively influence secondary school athletes’ likelihood of reporting symptoms of sport-related concussions?

Congruence between actual and retrospective reports for pre- and postcompetition emotional states was investigated separately and together. Fifty-two members of four university sport teams participated in one or more of three experimental conditions. The first condition consisted of actual measurement of precompetition emotional states and retrospective measurement of the same situation following a 72-hr delay. Actual and retrospective measurement of postcompetition emotional states comprised the second condition. The third condition included actual measurement of pre- and post-states and retrospective measurement of both states after a 72-hr delay. RM-MANOVA procedures revealed that athletes could report and differentiate between their pre- and postcompetition emotional experiences, and that retrospective report was not affected by the pre/post interference after a 72-hour delay. However, athletes underestimated the intensity of postcompetition unpleasant emotions. Correlations between the structured actual and retrospective measures of emotions were moderate to strong, and thus congruent. However, thoughts and feelings that were openly expressed after 72 hours were not fully congruent with thoughts and feelings reported in real time. These findings are discussed in relation to Ericsson and Simon’s (1980, 1984) conceptualization of verbal reports as data, and Ross’ (1989) implicit theory of stability and change.

Numerous instruments to measure self-reported physical activity (PA) exist, but there is little guidance for determining the most appropriate choice.
To provide a systematic framework for researchers and practitioners to select a self-reported PA instrument.
The framework consists of 2 components: a series of questions and a database of instruments. The questions encourage users to think critically about their specific needs and to appreciate the strengths and limitations of the available options. Instruments for the database were identified through existing literature and expert opinion.
Ten questions, ranging from study aim and study design to target population and logistical consideration, guide the researcher or practitioner in defining the criteria for an appropriate PA instruments for a given situation. No one question on its own determines the optimal choice, but taken together, they narrow the potential field. The database currently includes 38 different self-reported PA instruments, characterized by 18 different parameters.
The series of questions presented here, in conjunction with a searchable database of self-report PA instruments, provides a needed step toward the development of guiding principles and good practices for researchers and practitioners to follow in making an informed selection of a self-reported PA instrument.

To determine the test–retest reliability and criterion validity of self-reported function in mobility and instrumental activities of daily living (IADL) in older adults, a convenience sample of 70 subjects (72.9 ± 6.6 yr, 34 male) was split into able and disabled groups based on baseline assessment and into consistently able, consistently disabled, and inconsistent based on repeat assessments over 2 weeks. The criterion validities of the self-reported measures of mobility domain and IADL-physical subdomain were assessed with concurrent baseline measures of 4 mobility performances, and that of the self-reported measure of IADL-cognitive subdomain, with the Mini-Mental State Examination. Test–retest reliability was moderate for the mobility, IADL-physical, and IADL-cognitive subdomains (κ = .51–.66). Those who reported being able at baseline also performed better on physical- and cognitive-performance tests. Those with variable performance between test occasions tended to report inconsistently on repeat measures in mobility and IADL-cognitive, suggesting fluctuations in physical and cognitive performance.

The Report Card on Physical Activity for Children and Youth aims to consolidate existing evidence, encourage greater evidence-informed physical activity, and improve surveillance of physical activity.
The Japan report card followed the methodology of the Canadian and Scottish report cards, but was adapted to reflect the Japanese context. Nationally representative data were used to score each of the respective indicators.
The 2016 Japan Report Card on Physical Activity for Children and Youth consists of Health Behaviors and Outcomes (7 indicators), and Influences on Health Behaviors (4 indicators). Three Health Behaviors and Outcomes received C grades (Participation in Sport; Sedentary Behavior; Recreational Screen Time; Physical Fitness), while 2 indicators could not be graded (Overall Physical Activity, and Active Play). The indicators Active Transportation (B) and Weight Status were favorable (A). In the Influences domain, Family Influence and Community and the Built Environment were graded as D, while School and Government Strategies and Investments were favorable (B).
The Japan report card illustrated some favorable health behaviors, health outcomes, and influences. There is a need for more evidence especially on overall physical activity levels, active play, and community and the built environment.

Exercise effectively reduces symptoms of depression. However, correlates of regular exercise in depressed women are unknown. This study assessed psychosocial determinants of exercise in a sample of women with depressive symptoms.
Sixty-one women completed demographic, depression, and exercise-related questionnaires.
The average Primary Health Ques-tionnaire-9 (PHQ-9) depression score was 12.1 (SD = 5.0), indicating moderate depressive symptoms. In the previous week, the women reported 12.8 metabolic equivalents (METs) of exercise. Low levels of self-efficacy and social support for exercise were also reported. Depressive symptoms were positively associated with barriers to exercise (r = .35, P < .01), and barriers were inversely related to exercise METs (r = –.37, P < .05). Barriers to activity and education level were significant determinants of exercise.
Women with depressive symptoms report minimal exercise involvement, numerous barriers to exercise, and low exercise self-efficacy and social support for exercise.

Athlete self-report measures (ASRM) have the potential to provide valuable insight into the training response; however, there is a disconnect between research and practice that needs to be addressed; namely, the measure or methods used in research are not always reflective of practice, or data primarily obtained from practice lacks empirical quality. This commentary reviews existing empirical measures and the psychometric properties required to be considered acceptable for research and practice. This information will allow discerning readers to make a judgment on the quality of ASRM data being reported in research papers. Fastidious practitioners and researchers are also provided with explicit guidelines for selecting and implementing an ASRM and reporting these details in research papers.

Child-parent pairs (n = 109) completed a questionnaire assessing whether changes in normal physical activity levels occurred (child) or were observed (parent) when the children wore a pedometer for 7 days. Over two-thirds of the children (78.5%) and almost half of the parents (47.3%) indicated an increase in the child’s normal physical activity. Reduced television viewing (75.2%) and increased outdoor play on the weekend (35.8%) were the most frequently reported means of behavior change as reported by the children and parents, respectively. Results indicate that both children and parents perceive a reactive effect to wearing an unsealed pedometer.
