OBJECTIVE In rehabilitation research and practice, participation is defined as involvement in life situations and most often measured as frequency of engaging in these life situations. This narrow measurement approach overlooks that individuals perceive importance of and satisfaction with participation in activities in various life areas differently. The purpose of this study was to determine differences in meaningful participation (perceived importance and satisfaction) after moderate to severe traumatic brain injury (TBI) across age groups and to identify predictors of participation satisfaction. METHOD Secondary data analysis of a TBI Model Systems substudy, including the Participation Assessment with Recombined Tools-Subjective (PART-S) that rates participation importance and satisfaction in 11 life areas that we grouped into three domains (i.e., productivity, social relations, out-and-about). We identified differences across age groups (i.e., 16 to 24 years, 25 to 44 years, 45 to 64 years, and 65 + years) and predictors of participation satisfaction. RESULTS Participation satisfaction in and importance of the 11 life areas varied across age groups. In all age groups, participants rated relationships as being of medium or high importance more often than other life areas. Older adults reported the highest participation satisfaction across life areas, despite having the lowest participation frequency. Consistent predictors of participation satisfaction were cognitive functioning and frequency of participation in the domain examined. CONCLUSION Participation importance, satisfaction, and frequency are related, yet distinct, dimensions of participation that should all be measured to adequately evaluate meaningful participation. Future research should explore interventions across the lifespan that target modifiable predictors, like functional cognition and access to frequent participation in important life activities.

整个生命周期的参与重要性和满意度：创伤性脑损伤模型系统研究。

目标 在康复研究和实践中，参与被定义为对生活情境的参与，通常以参与这些生活情境的频率来衡量。这种狭隘的测量方法忽略了个人对参与不同生活领域活动的重要性和满意度的不同看法。本研究的目的是确定不同年龄组的中度至重度创伤性脑损伤 (TBI) 后有意义参与（感知的重要性和满意度）的差异，并确定参与满意度的预测因子。方法 对 TBI 模型系统子研究进行二次数据分析，包括使用重组工具-主观 (PART-S) 的参与评估，该评估对我们分为三个领域的 11 个生活领域的参与重要性和满意度进行评分（i. 例如，生产力、社会关系、外出）。我们确定了不同年龄组（即 16 至 24 岁、25 至 44 岁、45 至 64 岁和 65 岁以上）的差异以及参与满意度的预测因素。结果 11 个生活领域的参与满意度和重要性因年龄组而异。在所有年龄组中，与其他生活领域相比，参与者更频繁地将关系评为中等或高度重要。尽管参与频率最低，但老年人在生活领域的参与满意度最高。参与满意度的一致预测因素是认知功能和参与所检查领域的频率。结论 参与重要性、满意度和频率是相关的，但又是不同的，应衡量参与的维度，以充分评估有意义的参与。未来的研究应该探索针对可改变预测因素的整个生命周期的干预措施，例如功能性认知和频繁参与重要生活活动的机会。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
