Psychometrics Properties of Persian Version of Disagreement in Romantic Relationships Scale

Although conflicts and disagreements are inevitable in emotional relationships, they have many impressions on the quality and durability of the relationship. Clarifying the conflicts between the partners, in addition to being an effective step in evaluating the relationship, is a critical step of relationship assessment and a necessary factor in dissatisfaction intervention programs. Therefore, this study aims to prepare and standardize the Persian version of the Reasons for Disagreement in Romantic Relationship Scale (RDRRS).

As the research sample, 285 men and women living in Tehran, completed RDRRS, Relationship Assessment Scale(RAS), Relationship Quality Scale(RQS), and Oxford Happiness Questionnaire(OHQ) among which the last 3 ones were carried out for assessing the RDRRS validity. The construct validity was examined with the methods of confirmatory factor analysis and convergent and divergent validity through Pearson correlation. To check its validity by calculating Cronbach's alpha, the main test was re-administered for 30 participants after two weeks.

The factor analysis of RDRRS revealed six main factors: Inadequate Attention or Affection; Jealousy & Infidelity; Chores & Responsibilities; Sex; Control & Dominance; Future Plans & Money. The reliability coefficients using Cronbach Alpha were equal to 0.75 to 0.90 for the main factors, 0.82 for the total score, and 0.39 for the test-retest sample. Also, to check the convergent validity, a significant correlation was obtained between the factors of RDRRS with the relationship evaluation questionnaire and the divergent validity with the happiness questionnaire.

According to the acquired results, the Persian edition of RDRRS has a factorial structure the same as the original scale. The Persian edition of RDRRS is a suitable scale for studying disagreements among Iranian couples.
