Do formal religious participation and spiritual perceptions have independent linkages with diverse dimensions of psychological well-being?

Recognizing religiosity and spirituality as related yet distinct phenomena, and conceptualizing psychological well-being as a multidimensional construct, this study examines whether individuals' frequency of formal religious participation and spiritual perceptions are independently associated with diverse dimensions of psychological well-being (negative affect, positive affect, purpose in life, positive relations with others, personal growth, self-acceptance, environmental mastery, and autonomy). Data came from 1,564 respondents in the 2005 National Survey of Midlife in the United States (MIDUS). Higher levels of spiritual perceptions were independently associated with better psychological well-being across all dimensions, and three of these salutary associations were stronger among women than men. Greater formal religious participation was independently associated only with more purpose in life and (among older adults) personal growth; greater formal religious participation was also associated with less autonomy. Overall, results suggest a different pattern of independent linkages between formal religious participation and spiritual perceptions across diverse dimensions of psychological well-being.
