Abstract
Religiousness and spirituality (R/S) are consistently linked with positive indicators of well-being, but the mechanisms behind these associations remain largely unknown. We hypothesize that an individual's level of perceived control (PC) acts as a mediator of this relationship and that this effect is stronger in older adults. Participants were 529 adults from the Notre Dame Study of Health and Well-Being (aged 31-88). Regression analyses tested both mediating and moderating functions of PC for three different R/S components (religious practices, daily spiritual experiences, and religious/spiritual coping); composite variables were used for PC and subjective well-being (SWB) in all analyses. These effects were tested using the full sample, as well as separately by age group (early midlife, aged 31-49; late midlife, aged 50-59; and later life, aged 60 and over), in order to discover any age differences that may exist. Results revealed differences by both R/S dimension and age group: PC partially mediated the religious practices-SWB relationship in the full sample and in the later life group; the effects of religious/spiritual coping and spiritual experiences on SWB were partially mediated by PC in the full sample, the late midlife group, and the later life group; and none of the R/S-SWB relationships were mediated in the early midlife group. Moderating effects were indicated by significant interactions between PC and spiritual experiences in the full sample, PC and religious coping in the full sample, and PC and religious practices in the later life group.
