Contributo alla costruzione di uno strumento di valutazione della gelosia morbosa non psicotica

The research study involves the construction of an instrument for the assessment of non-psychotic morbid jealousy. Morbidly jealous individuals develop a cognitive schema--based on erroneous assumptions--that leads them to systematic distortions in the interpretation of events and excessive behavioural and emotional reactions, which produce severe repercussions on individual and couple functioning. In accordance with this formulation, a 64-item instrument has been devised. It is divided into four sections: cognitive, behavioural, emotional and a scale to assess the frequency with which jealousy ruminations interfere with couple relationship. The instrument was administered to a sample of 130 participants to verify its metric properties. Reliability and validity reached satisfactory levels. Single items showed good discriminant ability.
