Abstract
When applying self-determination theory to educational settings, evidence suggests that the basic psychological need of relatedness is actually multi-dimensional, which could result in differential influences on intrinsic motivation. Thus, this study proposes a modification to the operationalization of relatedness. The relatedness items from the adapted Basic Satisfaction Needs at Work scale were altered so that items asked students to separately report the amount of connection they feel with their instructors and peers, as opposed to the original items that asked them to more broadly reflect on people in their course. College students (556 female, 321 male) completed a questionnaire assessing their basic psychological needs, including the two new relatedness subscales, motivation, and academic outcomes. Results of exploratory and confirmatory factor analyses revealed that the original relatedness scale should, in fact, be treated as two-dimensional. In addition, of all the basic psychological needs, instructor relatedness was most predictive of student interest/enjoyment in the course and self-reported effort. Conversely, peer relatedness did not significantly predict any outcome variables. Study implications, limitations, and areas for future research are discussed.
