“…In sum, even though some evidence on similarity effects -in the form of difference scores, profile correlations, or interaction terms -exists for some personality dimensions, the evidence is mixed. We add to this literature by testing the effect of Big Five traits similarity on relationship satisfaction in couples using polynomial regression analysis (Edwards & Parry, 1993), which includes linear and curvilinear estimates between a predictor variable and an outcome measured in both partners.…”

“…These indexes range from directed and absolute difference scores, and profile correlations, to interaction terms. Aside from drawbacks discussed elsewhere (Edwards, 1993;Gaunt, 2006;Griffin, Murray, & Gonzalez, 1999;Nestler, Grimm, & Schönbrodt, 2015), difference scores, profile similarity, and interaction terms are often used to test congruence effects assuming a linear relationship (Edwards & Parry, 1993;Nestler et al, 2015). A hypothetical example for a linear association between similarity and satisfaction is that couples, which are very similar, report high relationship satisfaction, whereas couples that are dissimilar report low relationship satisfaction.…”

“…Testing polynomial regression models is more appropriate relative to the above reviewed similarity indices (Edwards & Parry, 1993). Thus, for ease of interpretation, we will display the results of each model on a surface (Edwards & Parry, 1993).…”

“…Thus, for ease of interpretation, we will display the results of each model on a surface (Edwards & Parry, 1993). Finally, we will compare each dyadic polynomial regression model with a model including only linear main effects to test whether this simpler model is able to explain the association between personality traits and satisfaction in couples comparably well as a dyadic polynomial model.…”

“…Because of the dyadic nature of our data, we followed current recommendations (Nestler et al, 2015;Schönbrodt, Humberg, & Nestler, 2017) Likewise, the LOIC is defined by a linear slope (a3) and by a curvilinear slope (a4) (Edwards & Parry, 1993;Schönbrodt, 2016;Shanock et al, 2010). An example for a linear slope on the LOIC would include individuals who report high relationship satisfaction if one partner reports a high trait level and the other partner reports low trait-level.…”

Being with a well-matched partner seems essential for a happy relationship. However, past research on personality similarity in couples has reported inconsistent findings. The current study employs a dyadic polynomial regression approach to take into account linear and curvilinear associations between similarity and satisfaction. The concurrent results based on data of 237 couples suggest that beyond actor effects for neuroticism, agreeableness, and conscientiousness and partner effects for agreeableness, similarity plays a negligible role for relationship satisfaction. Longitudinally, two similarity effects emerged. First, if partners reported dissimilar neuroticism levels, male partner reported lower relationship satisfaction. Second, if both partners reported modest levels in openness, female partners reported higher relationship satisfaction. Implications for couples are discussed.

Organizational behavior implications of the congruence between preferred polychronicity and experienced work-unit polychronicity

1999

View full text Add to dashboard Cite

SummaryThis research hypothesizes that greater congruence between preferred polychronicity (the extent to which an individual prefers to be involved with several tasks simultaneously) and experienced work-unit polychronicity (the polychronic behaviors and preferences of the supervisor and co-workers) will be associated with higher levels of (1) three components of organizational commitment (willingness to exert eort, desire to remain a member of the organization, and belief in and acceptance of organizational goals), (2) the individual's perceived performance evaluation by the supervisor and co-workers, and (3) the individual's perceived fairness of the performance evaluation. Based on a sample of employed business school graduates, the results indicate that polychronic congruence is signi®cantly related to these variables in the predicted direction. The use of polynomial regression analysis reveals additional characteristics of the relationships that would not have been available from the analysis of squareddierence scores. The ®ndings support the position that polychronicity and other temporal variables are important factors in organizational research.
