“…This deterioration might lead to a decline in both engagement in fitness activities and neurological health. 1,2,6 These findings emphasize the importance of lab-based metrics of fitness, 31 and future studies should evaluate fitness longitudinally to see if these markers of health confer additional risk for conversion and if they may be useful tools in targeting individuals at greatest risk.…”

“…This inconsistency further emphasizes the need for more objective accounts of exercise behaviors and fitness. 31 Finally, distortions in perceived fitness 31 were related to symptoms related to distortions in perception of self (i.e., grandiosity) and motivation (i.e., anhedonia). In summary, although lab-based measures demonstrate that individuals are less physically fit 40,41 than peers, the self-report measures of fitness 12 may reflect a mixture of actual fitness, subjective experience of fitness, and attenuated symptoms.…”

“…42,44,45 Alternatively, self-reported levels of intensity and time spent exercising may reflect the subjective experience of the individual. 31,39,46 As a result, individuals with a higher BMI may experience more difficulty exercising and report objectively less intense exercise as being more intense, and as lasting a longer period of time. In addition to biases of subjective experience, self-report of fitness behaviors may be further distorted by the presence of attenuated symptoms.…”

“…In addition to biases of subjective experience, self-report of fitness behaviors may be further distorted by the presence of attenuated symptoms. 31,46 Self-reports of perceived fitness 12 reflected overall severity of positive and negative symptoms, even when accounting for other features of health behavior (e.g., frequency and intensity of exercise). This finding suggests that self-reported perception of fitness may, in fact, reflect overall severity of attenuated symptoms of psychosis more than actual fitness.…”

“…14 This difference in physiological fitness among other risk populations 14 may indicate that physiological health metrics are more sensitive assessments for risk populations such as CHR. 20,22,27 Finally, it is possible that inconsistencies in fitness are driven by issues related to a self-report approach; self-report accounts of fitness behaviors have been found to have limited validity in capturing actual health behaviors [28][29][30] which may be exacerbated by psychosis-like experiences, 31 such as distortions in self-perception and memory.…”

Introduction:Exercise is a promising intervention for clinical high-risk for psychosis (CHR) populations, who have attenuated positive symptoms, but evidence suggests that these youth may require tailored exercise interventions. Presently, the scope of the problem is unknown, as these youth may not be reliable reporters on fitness. This issue is compounded by the fact that there have been no investigations that utilized a formal fitness assessment in this critical population.The present study aims to determine the level of fitness in CHR youth with lab-based measures, test how effectively self-report measures characterize objective fitness indices, and explore clinical factors that may be interrupting reliable self-report-an important tool if these interventions are to be taken to scale.Methods: Forty CHR individuals completed an exercise survey and lab-based indices of fitness (i.e., VO2max and BMI). Forty healthy volunteers completed lab indices of fitness and a structured clinical interview ruling out the presence of psychiatric illness.Results: CHR youth showed greater BMI and lower VO2max compared to healthy volunteers. In the CHR group, abstract self-report items (perceived fitness) did not reflect lab indices of fitness, whereas specific exercise behaviors (intensity of exercise) showed stronger correlations with laboratory-based fitness measurements. Exploratory analyses suggested that positive symptoms involving grandiosity, and negative symptoms such as avolition, correlated with discrepancy between self-perception and laboratory findings of fitness. Discussion:Results suggest that CHR individuals are less objectively fit than matched controls, and that it will be important to consider unique population characteristics when weighing selfreport data.

Current Evidence of Measurement Properties of Physical Activity Questionnaires for Older Adults: An Updated Systematic Review

et al. 2020

View full text Add to dashboard Cite

Background Questionnaires provide valuable information about physical activity (PA) behaviors in older adults. Until now, no firm recommendations for the most qualified questionnaires for older adults have been provided. Objectives This review is an update of a previous systematic review, published in 2010, and aims to summarize, appraise and compare the measurement properties of all available self-administered questionnaires assessing PA in older adults. Methods We included the articles evaluated in the previous review and conducted a new search in PubMed, Embase, and SPORTDiscus from September 2008 to December 2019, using the following inclusion criteria (1) the purpose of the study was to evaluate at least one measurement property (reliability, measurement error, hypothesis testing for construct validity, responsiveness) of a self-administered questionnaire; (2) the questionnaire intended to measure PA; (3) the questionnaire covered at least one domain of PA; (4) the study was performed in the general, healthy population of older adults; (5) the mean age of the study population was > 55 years; and (6) the article was published in English. Based on the Quality Assessment of Physical Activity Questionnaires (QAPAQ) checklist, we evaluated the quality and results of the studies. The content validity of all included questionnaires was also evaluated using the reviewers' rating. The quality of the body of evidence was evaluated for the overall construct of each questionnaire (e.g., total PA), moderate-to-vigorous physical activity (MVPA) and walking using a modified Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach. Results In total, 56 articles on 40 different questionnaires (14 from the previous review and 26 from the update) were included. Reliability was assessed for 22, measurement error for four and hypotheses testing for construct validity for 38 different questionnaires. Evidence for responsiveness was available for one questionnaire. For many questionnaires, only one measurement property was assessed in only a single study. Sufficient content validity was considered for 22 questionnaires. All questionnaires displayed large measurement errors. Only versions of two questionnaires showed both sufficient reliability and hypotheses testing for construct validity, namely the Physical Activity Scale for the Elderly (PASE; English version, Turkish version) for the assessment of total PA, and the Physical Activity and Sedentary Behavior Questionnaire (PASB-Q; English version) for the assessment of MVPA. The quality of evidence for these results ranged from very low to high. Conclusions Until more high-quality evidence is available, we recommend the PASE for measuring total PA and the PASB-Q for measuring MVPA in older adults. However, they are not equally qualified among different languages. Future studies on the most promising questionnaires should cover all relevant measurement properties. We recommend using and improving existing PA questionnaires-instead of developing new ones-...
