Affiliation motivation: people who need people ... but in different ways.

The Interpersonal Orientation Scale was developed to focus on four dimensions assumed to underlie affiliation motivation: social comparison, emotional support, positive stimulation, and attention. Factor analyses basically supported the proposed multidimensional construct. Evidence for the validity of the four dimensions was provided by their correlations with measures of constructs conceptually related to affiliation motivation and their lack of correlation with measures conceptually unrelated to affiliation motivation. Moreover, in a laboratory study, each motivational subscale tended to correlate most highly with role-played responses in a situation affording the relevant incentive type. Future research on social motivation and interaction will profit from identifying the particular incentives that are salient in a giving setting.
