“…Since its development, the ESI and the dimensional model have been used by MacDonald and others to examine the relation of spirituality to numerous aspects of functioning, including health, psychopathology, substance use, sexual orientation, boredom proneness, anomalous temporal lobe signs, trait personality, empathy, altruism, and work and organizational values and behavior (e.g., Adamovova and Strizenec, 2004;Affeldt and MacDonald, 2010;Bliss, 2009Bliss, , 2011Boyd-Starke et al, 2011;Huber and MacDonald, 2012;MacDonald and Holland, 2002a, 2002b, 2003. As importantly, they have served as the basis for theory development and/or validation in the creation of new models and measures of spirituality and religiosity (e.g., Kassab and MacDonald, 2011;MacDonald, 2009MacDonald, , 2011aMacDonald and Holland, 2002c;Saucier and Skrzypinska, 2006).…”
