Abstract

Identity is among the most robust psychological constructs for predicting whether individuals translate physical activity (PA) intentions into action. However, existing identity measures in the PA domain focus narrowly on exercise and largely adopt limited unidimensional conceptualizations. This study aimed to develop and validate the Multidimensional Inventory of Physical Activity Identity (MIPAI-25), a novel instrument grounded in a multidimensional, theoretically integrated framework. Across two samples of university students (Study 1: n = 580, 61.6 % women; Study 2: n = 619, 66.4 % women), we used classical test theory, Mokken scale analysis, and item response theory to construct and refine the content relevancy of the items for each scale. In Study 1, the final 25-item instrument captures five distinct dimensions of PA identity: Acknowledgment, Compatibility, Centrality, Commitment, and Exploration. Each subscale score demonstrated strong internal consistency, unidimensionality, and measurement invariance across gender groups. In Study 2, all five dimensions were positively associated with moderate-to-vigorous PA behavior and PA-related constructs from the Multi-Process Action Control framework, with the strongest associations observed for habit and behavioral regulation – key post-intentional processes that facilitate action control. The MIPAI-25 offers a more ecologically valid and dynamic representation of PA identity, extending beyond exercise-specific and unidimensional measures. Findings support its use as both a comprehensive tool and a set of five stand-alone subscales, depending on research or practical needs. Future longitudinal studies are needed to explore how these identity dimensions evolve across life transitions and to inform more targeted, identity-based interventions for promoting sustained physical activity.

体育活动认同多维度量表的开发

身份是预测个体是否将体育活动（PA）意图转化为行动的最强大的心理结构之一。然而，现有的PA领域的身份测量只局限于运动，并且很大程度上采用了有限的一维概念。本研究旨在开发和验证多维身体活动认同量表（MIPAI-25），这是一种基于多维理论整合框架的新工具。在两个大学生样本中（研究1:n = 580，女性占61.6%；研究2:n = 619，女性占66.4%），我们使用经典测试理论、Mokken量表分析和项目反应理论来构建和完善每个量表项目的内容相关性。在研究1中，最后的25项工具捕获了个人助理身份的五个不同维度：承认、兼容性、中心性、承诺和探索。每个子量表得分在性别群体中表现出很强的内部一致性、单维性和测量不变性。在研究2中，所有五个维度都与中度至重度PA行为和多过程行动控制框架中的PA相关构念呈正相关，其中习惯和行为调节（促进行动控制的关键后意向过程）的关联最强。MIPAI-25提供了一种更生态有效和动态的PA身份表征，超越了特定运动和单向度的测量。根据研究或实际需要，研究结果支持将其作为一种综合工具和一套五个独立的子量表。未来的纵向研究需要探索这些身份维度如何在生活转变中演变，并为更有针对性的、基于身份的干预措施提供信息，以促进持续的身体活动。

期刊介绍： Psychology of Sport and Exercise is an international forum for scholarly reports in the psychology of sport and exercise, broadly defined. The journal is open to the use of diverse methodological approaches. Manuscripts that will be considered for publication will present results from high quality empirical research, systematic reviews, meta-analyses, commentaries concerning already published PSE papers or topics of general interest for PSE readers, protocol papers for trials, and reports of professional practice (which will need to demonstrate academic rigour and go beyond mere description). The CONSORT guidelines consort-statement need to be followed for protocol papers for trials; authors should present a flow diagramme and attach with their cover letter the CONSORT checklist. For meta-analysis, the PRISMA prisma-statement guidelines should be followed; authors should present a flow diagramme and attach with their cover letter the PRISMA checklist. For systematic reviews it is recommended that the PRISMA guidelines are followed, although it is not compulsory. Authors interested in submitting replications of published studies need to contact the Editors-in-Chief before they start their replication. We are not interested in manuscripts that aim to test the psychometric properties of an existing scale from English to another language, unless new validation methods are used which address previously unanswered research questions.
