Abstract
The purpose of this study was to examine whether early and middle adulthood siblings' use of relational maintenance behaviors (i.e., positivity, openness, assurances, networks, tasks) is predicted, after controlling for relational closeness, by their interpersonal communication motives (i.e., affection, inclusion, control, pleasure, relaxation, escape). Participants were 122 individuals who reported on their relationship with a sibling. Results indicated that for the positivity relational maintenance behavior, psychological closeness, the affection motive, and the control motive were significant contributors; for the openness, assurances, and tasks relational maintenance behaviors, psychological closeness and the affection motive were significant contributors; and for the networks relational maintenance behavior, psychological closeness was a significant contributor.

Prior to reporting each regression analysis, multicollinearity was assessed through an examination of the tolerance statistic and the variance inflation factor (VIF) statistic for each analysis. Mertler and Vannatta (Citation2002) stated that tolerance statistics that are .10 or less (based on Norusis, Citation1998) and VIF statistics that are greater than 10 (based on Stevens, Citation2002) are indicators that multicollinearity is an issue. Among the independent variables (i.e., the six interpersonal communication motives, the three dimensions of relational closeness), the lowest tolerance statistic was .22 and the highest VIG statistic was 4.47. Based on these statistics, it was determined that multicollinearity was not an issue.
