Abstract: | Trait loyalty has received virtually no attention from researchers; consequently, the basic goal of this research was to create a measure of interpersonal loyalty. Principal factor analyses of an initial pool of items revealed 2 factors: Individual Loyalty (e.g., “I stand by my friends, even when they make mistakes”) and Group Loyalty (e.g., “I am loyal to my country”). Analyses of a revised item pool identified the same 2 factors in a second sample. Scales based on these factors were internally consistent and only moderately related to one another. Additional analyses indicated that both scales (a) were stable over time; (b) showed moderate to strong self-peer agreement; (c) positively correlated with conscientiousness, agreeableness, altruism, and positive emotionality; and (d) negatively related to an avoidant attachment style. However, these associations all were moderate in magnitude (in fact, none was as high as |.40|), indicating that the Individual and Group Loyalty Scales tap unique variance that is not captured by existing instruments. |
