Primary use / Purpose:
Background:
Evolutionary psychologists hypothesised over three decades ago that men and women would differ psychologically in the weighting given to cues that trigger jealousy (Symons, 1979). A man's jealousy has been hypothesised to focus on cues to sexual infidelity because a long term partner's infidelity jeapordises his certainty in paternity, thereby placing him at risk of investing in another man's offspring. A woman's jealousy has been hypothesised to relate to cues to the long-term diversion of a man's commitment. The Jealousy Instrument is a 22 item questionnaire of events relating to relationship history, and current feeling on partner's capacity for infidelity.
