This investigation assessed the psychometric properties of the Emotional Tolerance Scale within the context of married couples in Riyadh. In pursuit of the research objectives, the 15-item, four-dimensional scale was translated and administered to the designated cohort. The study sample comprised 628 married participants. The investigation conducted a comprehensive assessment of validity types, wherein translation, content, and internal consistency were established as satisfactory. Exploratory factor analysis delineated four distinct factors within the measurement framework: tolerance, recommendation, comprehension, and organization. The Kaiser-Meyer-Olkin (KMO) test yielded a result of 0.638, surpassing the requisite threshold of 0.6, affirming the adequacy of the sample size for factor analysis. Significance in Bartlett's sphericity test underscored the relevance of item linkages, rendering the item correlation matrix conducive to factor analysis at a significance level of 0.05. The application of Guilford's rule in factor analysis revealed item saturation, accepting bifurcations with values greater than or equal to 0.3. Additionally, factors meeting or exceeding an eigenvalue of one, as per the Kaiser criterion, were retained. The Emotional Tolerance Scale's constituent elements and dimensions for spouses were observed to coalesce into a singular factor. All correlation coefficients were statistically significant at the 0.01 level, ranging from 0.620 to 0.0725, indicative of the interconnectedness of all items within the tool. Furthermore, the instrument demonstrated robust internal consistency, as evidenced by Cronbach's alpha and the semi-reliability coefficient, both surpassing 0.80. These values align with the research objectives, affirming the reliability of the instrument and its congruence with the study's empirical foundations.
