The purpose of the present study is to develop and evaluate psychometric properties of the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS). In terms of testing, the research method was of descriptive type and the sampled statistical population included married men and women living in the city of Tehran, Iran. In this respect, 470 Iranian married men and women (277 women and 193 men) volunteered to participate in the given study.
The resulting scale in this study was the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS). To develop this scale, the first step involved planning for the subject matter of the test and the second step contained designing a questionnaire based on theoretical foundations and reviews of existing questionnaires. The given scale was implemented in two stages and the final questionnaire was analyzed in order to assess its construct validity through measurement methods including internal consistency (Cronbach’s alpha coefficient), Pearson correlation coefficient, test-retest method, exploratory factor analysis, as well as confirmatory factor analysis.
According to the findings of this study, Cronbach’s alpha coefficients (internal consistency) were from 0.65 to 0.78 and the results of the test-retest method confirmed the correlation coefficients between 0.54 and 0.81. In this regard, the results of confirmatory factor analysis revealed a goodness of fit index (GFI) equal to 0.95. Likewise, the goodness of fit index (GFI) was 0.95 and the adjusted goodness of fit index (AGFI) was equal to 0.91 which showed a favorable goodness of fit for the model. The normed fit index (NFI) and the comparative fit index (CFI) were respectively equal to 0.93 and 0.95 indicating the desirable goodness of fit for the model. Furthermore, the root mean square error of approximation (RMSEA) was 0.43 which suggested a favorable goodness of fit for the given model. The results of this study showed that the Intrapersonal and Interpersonal Skills of Couples Scale (IISCS) benefited from sufficient reliability, validity, and goodness of fit to measure such constructs among Iranian samples.
