Development of a Dyadic Partner Validation Scale Stumpe, Tiina-Mai


Self-validation is a process of restoring or enhancing one's wellbeing around the five interrelated thematic components of the self-validation model developed by Ishiyama, (1987, 1989). The thematic components of comfort, support,and security: self-worth and self-acceptance; competence, and autonomy; identity and belonging; and love, fulfillment and meaning in life are essential for self-validation and relationship validation. The Dyadic Parmer Validation Scale was developed to measure this construct This study tested the psychometric properties of Dyadic Partner Validation Scale. Item-total correlations ranged from .24 - .93, internal consistency correlations (Cronbach alpha) at .82, .81 and .70 and with a test-retest coefficient of .79 and .85 over a three week time period. Reliability correlations for the Dyadic Partner Validation Scale were high. As hypothesized, relationship validation measured by the Dyadic Partner Validation Scale had high positive correlation (.59, .75 and .78) with relationship satisfaction measured by the Dyadic Adjustment Scale. This hypothesis was accepted. It was hypothesized that relationship validation would have high negative correlations (.19, -.21 and -.30) with self-esteem measured by Rosenberg's Self Esteem Scale and high negative correlations ( .01, -.17 and -.33) with indices of mental health measured by Hopkin's Symptom Checklist This hypothesis was not supported but the correlations were moving in the expected negative direction. The Dyadic Partner Validation Scale was found to have predictive validity with relationship satisfaction. This scale provides a useful assessment tool for clinical and research purposes in studying marital and nonmarital relationships. Limitations of the study and theoretical and clinical implications are discussed. Further scale validation is recommended, and clinicians may consider using this instrument for exploratory purposes.
