摘要

本研究的目的是改善成人肥胖患者体力活动自我效能(PASE)的测量。为了实现这一目标，使用潜在变量方法来探索对新开发的PASE量表的响应的维度，时间不变性和外部有效性。数据(基线= 461和基线后N30天= 427)来自幸福感和身体活动研究(ClinicalTrials.gov，识别码:NCT03194854)，该研究部署了健康乐趣干预。二维因子结构解释了基线时对每个PASE量表的反应。有强有力的证据表明，在每个PASE量表中，这种二维结构至少部分时间测量不变性。有不同的证据表明，在这个二维结构的基线后30天，“健康乐趣”干预的有效性对肥胖成人的潜在PASE(即外部效度)有直接影响。

Measurement of Physical Activity Self-Efficacy in Adults With Obesity: A Latent Variable Approach to Explore Dimensionality, Temporal Invariance, and External Validity.

The objective of this study was to improve the measurement of physical activity self-efficacy (PASE) in adults with obesity. To accomplish this objective, a latent variable approach was used to explore dimensionality, temporal invariance, and external validity of responses to a newly developed battery of PASE scales. Data (Nbaseline = 461 and N30 days postbaseline = 427) from the Well-Being and Physical Activity Study (ClinicalTrials.gov, identifier: NCT03194854), which deployed the Fun For Wellness intervention, were analyzed. A two-dimensional factor structure explained responses to each PASE scale at baseline. There was strong evidence for at least partial temporal measurement invariance for this two-dimensional structure in each PASE scale. There was mixed evidence that the effectiveness of the Fun For Wellness intervention exerted a direct effect on latent PASE in adults with obesity at 30 days postbaseline (i.e., external validity) of this two-dimensional structure.

期刊介绍： The Journal of Sport & Exercise Psychology (JSEP) is a peer-reviewed publication designed to stimulate and communicate research theory in all areas of sport and exercise psychology. JSEP emphasizes original research reports that advance our understanding of human behavior as it relates to sport and exercise. Comprehensive reviews employing both qualitative and quantitative methods are also encouraged, as well as brief reports of soundly designed research studies that are of special interest or importance. Areas of interest include research in social, clinical, developmental, and experimental psychology, as well as psychobiology and personality. Moreover, the terms sport and exercise may pertain to either the independent or dependent variables. Generally speaking, work on motor control processes, studies of sport as a social institution, or broader social issues are beyond the scope of JSEP. A wide variety of methods are acceptable for studying sport and exercise psychology topics.
