The present study explores the validity of a recent stages of change (SoC) measure and algorithm among a sample of late adolescents. MANOVA and structural equation modeling are used to assess the relationship between five SoC groups (precontemplation, contemplation, preparation, action, and maintenance) and a set of dependent measures including physical activity level, physical activity motivation, physical self-concept, and flow. Findings are based on 705 Australian adolescents, using scale score and latent variable approaches, provided support for the construct validity of the SoC measure and algorithm. Specifically, findings reveal that participants in the upper SoC (action and maintenance) score significantly higher on positively geared dimensions (e.g., physical self-concept, flow, etc.) and significantly lower on negatively geared dimensions (e.g., maladaptive behavior). Implications for future research and practice with adolescent populations are discussed.
本研究探讨了一种近期变化阶段（SoC）测量和算法在青少年样本中的有效性。MANOVA 和结构方程模型被用于评估五个 SoC 组（前沉思、沉思、准备、行动和维持）与一组依赖测量之间的关系，包括身体活动水平、身体活动动机、身体自我概念和流畅性。研究结果基于 705 名澳大利亚青少年，使用量表得分和潜在变量方法，为 SoC 测量和算法的结构有效性提供了支持。具体而言，研究结果表明，处于较高 SoC（行动和维持）的参与者在积极导向维度（例如身体自我概念、流畅性等）上的得分显著更高，而在消极导向维度（例如适应不良行为）上的得分显著更低。讨论了未来在青少年群体中进行研究和实践的意义。
