Dyadic longitudinal interplay between personality and relationship satisfaction: A focus on neuroticism and self-esteem
The current study investigated the dyadic longitudinal interplay between neuroticism, self-esteem, and individual and shared aspects of relationship satisfaction in intimate partners. The study involved data of 141 heterosexual couples with a broad age range measured at two measurement occasions spaced 2 years apart. The analyses were based on Actor�Partner Interdependence Models and extended Common Fate Models. Regarding individual relationship satisfaction, neuroticism was found to be a predictor at the intrapersonal level, whereas self-esteem turned out to be an interpersonal outcome. Furthermore, shared relationship satisfaction predicted self-esteem 2 years later. The findings contribute to the literature by showing that relationship satisfaction can be both outcome and predictor depending on the personality trait and the model applied for dyadic data analysis.
In this paper we develop a new approach to evaluate the importance of technical features and engineering characteristics in the eyes of the customer by combining (1) the estimated influence of these so-called product characteristics on relevant product attributes in the eyes of the customer with (2) the estimated importance of these attributes for the customer. For both estimations conjoint analysis is applied. The new approach is compared to the traditional one w.r.t. predictive validity. Two sample applications are used for demonstration. We show that the new approach outperforms the traditional approach.
