  1. Semi-partial correlation reflects the unique relationship between each variable and the given scale score (N = 105)
  2. *p < .05, **p < .01, ***p < .001
  3. aBeta represents the coefficient when the entry score is the lone predictor, the semi-partial is that from the full-model regression
  4. bRepresents the variance explained by the entry score alone
  5. cDesignates dummy variable where “1” represents an individual of that religious affiliation
  6. dDesignates dummy variable where “1” represents an individual whose major is in that division
  7. eCalculated by the following equation: , where the subscripts i and f indicate the value after the initial block and the final block are entered
