Much of our work on forgiveness in the past few years has used a self-report measure called the Trasngression-Related Interpersonal Motivations (TRIM) Inventory. The version of the TRIM that is most widely in use right now is the TRIM-12. Here is a version of the TRIM-12 that includes scoring instructions, and techincal and psychometric information. All credit to Dr. Susan Wade (now Susan Wade Brown) for developing these items as part of her doctoral dissertation at Fuller Theological Seminary in Pasadena, CA.
More recently, we have also been using an 18-item form of the TRIM that includes items for measuring positive, benevolent motivations. The items comprising the 18-item form appear in this article. Here are the items and scoring instructions.

Much of our initial work on gratitude
has been devoted to examining the disposition to experience gratitude as a relatively
stable affective trait. To measure this affective trait, we have developed a
short scale called the Gratitude Questionnaire, whose current incarnation consists
of six short self-report items. The GQ-6 is
available here for download in PDF format. This
document includes some interpretative material that allows one to determine
where a person's score on the GQ-6 falls relative to a large sample of adults
who recently completed the measure. Finally, this short technical
document describes the psychometric properties of the scale, including some
of the most important evidence for its reliability and validity.
