Little effort has been made to systematically assess the determinants and consequences of marital jealousy which affect marital, familial and extra-familial expectations, interactions and behavior. A preliminary attempt to rectify this omission provides a conceptual/theoretical perspective on jealousy dynamics in marriage. Marital jealousy, a perceptual phenomenon, refers to the perceived threat of diminution or loss of the valued resources of the spouse and is distinguishable from envy. An analysis of a jealous situation should include descriptions of the normative orientation, the exchange dynamics, the development of competition, and the two major dimensions of marital jealousy, i.e., power and esteem. Four types of jealousy exist in marital situations: possession, fear, ideal-self- and exclusion jealousy. Some solutions to marital jealousy include increasing the mutual commitment of the partners and developing mutual trust in the relationship. (Author/KMF)
