Good, bad, and beyond: Perils of partialing positive and negative couple variables within individuals.

Journal of Family Psychology, Vol 37(1), Feb 2023, 31-36; doi:10.1037/fam0001044Partialing correlated predictors to test independent effects is an essential tool in couple research. In actor–partner models, partners’ parallel scores are partialed in tests of unique associations with outcomes. Correlated aspects of couple functioning are also often partialed within individuals to examine separate effects. Partialed versions of measures are typically interpreted as assessing the same construct as original unadjusted variables, but in fact their meaning can change. Extending a prior report on changes in construct validity resulting from partialing partners’ parallel scores, the present analyses examined effects of partialing measures of positive and negative relationship variables within individuals, specifically perceived support from the partner and relationship conflict. In 300 middle-aged and older couples, we utilized participants’ interpersonal circumplex ratings of their partner’s typical behavior during marital interactions to compare interpersonal correlates of unadjusted and within-person partialed forms of the Quality of Relationships Inventory Support and Conflict scales. Compared to unadjusted scores, partialed support scores (i.e., adjusted for conflict) were substantially less closely associated with ratings of partner’s warmth, and were associated with a less submissive (i.e., less agreeable, cooperative) form of warmth. Compared to unadjusted scores,...
