Enhancing construct validity evidence of the Daily Experiences of Pleasure, Productivity and Restoration Profile

ABSTRACT

The purpose of this study was to further assess the psychometric properties of the PPR Profile, a newly developed tool which assesses people's experiences of pleasure, productivity, and restoration in the occupational context of their time use. The relationships between mean pleasure, productivity and restoration scores, a global indicator of occupational experience and measures of meaning in life, positive and negative affect, and life satisfaction were examined using data from students (n=266) from a western university in the United States. Relationships were examined using multiple regression models. Validity evidence of the PPR Profile based on relationship to other variables was found. Daily mean pleasure and daily mean productivity were statistically significant predictors of a global assessment of occupational experience, meaning in life, positive affect, and life satisfaction. When controlling for global occupational experience, pleasure helped explain positive and negative affect and satisfaction with life, whereas productivity contributed to explaining meaning in life and positive affect. Daily mean restoration was not a significant predictor of global occupational experience or any of the well-being variables. The findings support the validity of the PPR Profile and the importance of examining various ways of assessing occupational experience. Implications for future research are presented.

这项研究的目的是进一步评估PPR文档的心理学特性。这是一个新开发的工具，用作测量人们在进行休闲活动时所经历的快乐、生产力和恢复。平均愉悦、工作效率和恢复分值之间的关系是一种综合性休闲经历指标，测定人生意义、正负影响和生活满意度。本文用美国西部一个大学的学生资料（n=266）对此进行了研究。我们采用多元回归模型来研究这种关系。基于与其它变量的关系，PPR文档的有效性证据得以发现。日均快乐和日均效率是综合性评估休闲体验、人生意义、积极影响和生活满意度的重要统计学预测指标。将综合性休闲体验作为控制因素，愉悦有助于解释正负面影响和生活满意度，而生产力有助于解释人生意义和积极影响。日平均恢复不是综合性休闲体验或任何幸福感变量的重要预测指标。这些发现支持PPR文档的有效性及检查评估休闲体验的各种方法的重要性。本文显示出对未来研究的意义。
