The Interpersonal Generosity Scale (IGS) described below is designed to measure the degree
to which individuals spend themselves (i.e., their attention, time, emotion, energy, etc.) to enhance the
well-being of others in interpersonal relationships. Interpersonal generosity (IG) can be
conceptualized as relationship “work” that persons engage and through which they expend
themselves in order to increase the good of the other(s) in the relationship and of the relationship
itself. Our premise is that variance at the level of persons exists in IG, which is worth studying.Some
people are extremely generous and others are more stingy when it comes to the giving of themselves
in interpersonal relationships. We further assume that these differences have multiple, significant
consequences in personal and social life. We believe that IG is an important, though neglected, form
of generosity to which scholars who study generosity, altruism, helping, pro-social orientations,
love, and related matters ought to pay greater attention. To that end, we have developed and tested the
IGS, described as follows.
Conceptual Definition
Although IG is closely related to—and in certain cases overlaps—the concepts of altruism,
pro-social orientation, helping, love, and other similar idea, IG involves several dimensions that give
it a particular conceptual specificity. First, IG always involves and is expressed through social
relationships. IG is not simply about a general orientation to life or people, as an abstract disposition
toward some larger social “good.” Second, IG focuses on behaviors of giving, by asking directly
about giving behaviors and indirectly about tendencies toward and identities related to giving to
others. Third, what are generously given in IG are resources of the subjective self, not simply
extrinsic or easily objectifiable resources such as money, labor, or even blood. In IG, persons always
expend irreducibly personal goods, such as attention, emotions, and energy, not impersonal goods.
Fourth, IG need not be purely altruistic. Since even the most loving relationships normally involve
some amount of reciprocity, exchange, and mutuality, genuine IG can be expressed with the
expectation, conscious or subconscious, in part that the giver in the relationships will also receive
back in some way(s) and at some time. To be sure, we do not conceive of IG in terms of a strict,
rational, immediate exchange designed to maintain relational equity or equilibrium. But neither do we,
as a matter of principle, rule out the generous IG giver also benefitting from reciprocated giving and
reward in the relationship.
Constructing the Scale
The final IGS instrument contains 10 items, measuring six identifiable dimensions of
interpersonal generosity: attention, compassion, openhandedness, self-extension, courage, and verbal
expression. Preliminary versions of the instrument contained up to 26 items (see Appendix A). Most
of those questions were derived from established personality and value scales, in particular those
developed by Penner et al. (1995) and McCullough and Bono (n.d.). Some of those items were
slightly revised for present purposes, while some were used verbatim. A number of other items were
written by us as original questions. Appendix A displays the 26 items used in the original,
