A growing body of research connects spirituality with positive late-life functioning. In this research, spirituality is often approached as a single measure in relation to well-being, neglecting its complex nature. Therefore, this study explores whether different dimensions of spirituality contribute uniquely to psychological well-being in advanced age. Results indicated that well-being was positively predicted by spirituality experienced through connectedness with the transcendent and through connectedness with others. Spirituality experienced through connectedness with nature did not predict well-being. These findings highlight the unique influence of each spirituality dimension on well-being as well as the need for a multidimensional approach.
