Infidelity is a harmful and a main problem in the therapy of couple relationships. The present study examined the reliability, validity and factor structure of the attitudes toward the infidelity scale among the patients referred to counseling centers in Tehran. 528 participants (185 females and 343 males) were selected by convenience sampling method from 5 centers. The study instrument was Whately's attitudes toward infidelity scale, which translated by 7 psychologists & back translated by an English expert. After a pilot study on 30 participants, the necessary corrections were made. The structure of the scale factor was confirmed in a first-order factor using confirmatory factor analysis. This scale had a good internal consistency (Cronbach's alpha=0.71 and test-retest=0.87) It had correlation with Alport internal and external religious orientation scale respectively 0.29 and 0.16, also negative correlation with Kansas Marital satisfaction scale and Enrich sexual satisfaction subscales (-0.22 and-0.16 respectively). This study showed that ATIS is an efficient tool for research and couple counseling and has an appropriate validity and reliability for Iranian society.

Objectives This study aimed to evaluate the discriminant validity of family adaptability and cohesion evaluation subscales. We investigated families referring to counseling, family courts, substance dependence treatment centers, and healthy and clinically defined cutoff scores for the breakdown of healthy Iranian families. Methods This scale was validated by four psychologists and translated by a professional English translator. After conducting a pilot study on 30 subjects, the necessary corrections were made to the scale. Families from 7 provinces (N=1652 subjects, parents=558, mothers=576, mothers and children=518) responded to the scale. For data analysis, univariate Analysis of Variance (ANOVA) and multivariate operating characteristic curves were used. Results The obtained results suggested that family mean normal score in all groups, clinical counseling, substance dependence, and family courts subscales suggested significant differences in terms of adverse life events, family interactions, family satisfaction, integrity, balance, flexibility, intertwined, torn, confused, and frustrated that there is flexibility (P<0.05). Conclusion The operating characteristic curve analysis to determine cutoff scores revealed the cutoff scores of family adaptability and cohesion evaluation subscales between normal and clinical diagnosis established optimum. Psychometric properties of the Persian version of family adaptability and cohesion evaluation is applicable for psychological research and clinical diagnosis.

Reproduction of scoring and interpretation of conceptual model underlying global measure of relationship satisfaction (GMREL) scale are prerequisites to the use of it in cross-cultural studies. This study was carried out to examine the factor structure and the psychometric properties of the Iranian version of GMREL. The participants of this study consisted of 299 patients (men=128 and women=171) who attended to counseling centers in Tehran. The GMREL, attitudes toward infidelity scale, Kansas marital satisfaction scale, and Enrich sexual satisfaction subscale were used for data collection. Results supported the internal consistency, test re-test reliability, and concurrent validity of GMREL. The confirmatory factor analysis of data supported first-order factor model includes 6 items. Our results confirmed the predicted relationships between GMREL and attitudes toward infidelity, marital satisfaction, and sexual satisfaction and also revealed the construct validity of GMREL translation among Iranian population. This study showed that GMREL has appropriate validity and reliability for Iranian sample and can be used as reliable, valid, and cross-cultural instrument.
