To investigate the emotional parameters of jealousy and to examine the differences between male and female labeling of jealousy, 288 college undergraduates completed the Emotional Parameters of Jealousy Questionnaire. The questionnaire consists of 59 statements that refer to emotions experienced by a person in a situation in which he/she feels jealousy toward another person. The results revealed four emotional components of jealousy that were labeled "disgust,""chagrin,""despair," and "distress." Males and females were found to differ significantly in the labeling of jealousy toward same-sex target persons. The findings suggested that a jealous person expresses feelings associated with a lack of self-confidence, a general dislike for a target person, and disappointment with a partner. They also suggest that males are primarily concerned with a loss of face when confronted with a jealousy situation, while females are concerned with the possible loss of a partner. (FL)
