Abstract
Background:The seven deadly habits are all the basic behaviors of external control psychology that harm and destroy relationships and, in doing so, cause almost all the problems with which people struggle.Objective:The main purpose of this research was to construct and validate an instrument that operationalizes Glasser’s constructs of seven deadly habits in marriage.Method: The theoretical principles of the deadly habits in marriage based on the Choice theory perspective were studied first. Then, the researchers designed a questionnaire based on the framework resulted from studying the achieved resources. After studying the form and content validity of the raisedquestions in relation to each of the sub-scales and removing the inappropriate ones, 68 questions were performed for the final performance on a group composed of 250 married students (213 females and 37 males) of Allameh Tabataba’i University. To investigate the reliability, two methods of internal consistency (Cronbach's Alpha) and split-half were applied, and the validity was determined from three aspects of construct validity (factor analysis), concurrent validity and content validity.Results:A factor analysis, using the principal components analysis (direct oblimin rotation) resulted that determined 7 factors consisted of 58.989% of the total variance. The Cronbach’s alpha for the whole scale was 0.95 (first factor: 0.82, second factor: 0.76, third factor: 0.78, fourth factor: 0.83, fifth factor: 0.76, sixth factor: 0.82, and seventh factor: 0.71), and split-half reliability was 0.957. We assessed the concurrent validity of the “Quality of Marital Relationships” (QMR) Scale in relation to the “Four Horsemen” subscale of Sound Relationship House Scale (SRH), and the result was 0.567. Conclusion:It can be concluded that the “Quality of Marital Relationships” scale has a good reliability and validity, and is useful instrument to assess deadly habits in marital relationship based on the choice theory.
