| Abstract | The discipline of occupational science was founded in response to the need for the explication of the form, function and meaning of occupation (the day to day activities that make up our lives). As a working assumption of occupational science, our daily occupations are imbued with personal meanings that contribute to the perception of purpose and meaning in our lives, ultimately influencing our health and well-being. Further, meaningful activity participation holds a central place in contemporary models and theories in social gerontology. Despite the importance of meaningful activity participation, no instrument exists which has been shown to validly tap the richness of this key construct. The present study addresses the development and validation of the Meaningful Activity Participation Assessment (MAPA), which is intended as a measure this vital conceptual domain.; The study began by utilizing focus groups and the input of the University of Southern California Well Elderly II research team to derive the 28-item MAPA. Data analyses were liberal in exploring the many facets of the MAPA scales, including tests of six main study hypotheses utilizing a sample of 154 older adults: 1) Among community dwelling older adults there is a positive correlation between the MAPA and the Purpose-in-Life test; 2) Among community dwelling older adults there are positive associations between the MAPA scales and other scales of meaningful activity participation; 3) Among community dwelling older adults there are positive correlations between the MAPA and two measures of life satisfaction (i.e., LSI-Z and SWLS); 4) Among community dwelling older adults there is a positive correlation between the MAPA and the four SF-36v2 Mental Health scales; 5) Among community dwelling older adults there is a positive correlation between the MAPA and the four SF-36v2 Physical Health scales; and 6) Among community dwelling older adults there is a negative correlation between the MAPA and the CES-D.; Results from the statistical tests of these hypotheses were intended to provide construct validity evidence for the MAPA. Zero-order correlation, multiple regression analysis, principal component analysis, cluster analysis, and a tentative causal model were employed as tests of the construct validity of the MAPA.; The results of these analysis offered nearly unequivocal support for the construct validity of the MAPA. Each of the study's main hypotheses was partially or fully supported, as the MAPA achieved statistically significant theoretically anticipated zero-order correlations with criterion measures. The MAPA was also found to hold adequate test-retest and internal consistency reliability. Additionally, in multiple regression models, the MAPA contributed to the prediction of every psychological well-being indicator, and all but one measure of health-related quality of life. Results of the cluster analysis found three clusters for which the members were found to have low, medium or high MAPA scores respectively. Profiles of these clusters discerned that, in general, low MAPA scores were associated with lesser psychological well-being and health-related quality of life. Results of the causal model were mixed, though the MAPA was found to contribute directly to the Purpose-in-Life test, whereas, together the MAPA and Purpose-in-Life test predicted the mental health component of version 2 of the SF-36v2 Health Survey.; Discussion of the study findings related to the significance of the MAPA as a reliable and valid measure of meaningful activity participation, in addition to the potential role the MAPA could serve in informing contemporary life-span theories of aging. Future research suggestions included the need for continued validation studies of the MAPA, including larger more representative samples, as well as longitudinal and experimental designs to consider the nature of change in the personal meaning of activities in older adults. |
