Validation of Interpersonal relationship scale inventory: Confirmatory factor analysis modelling approach using AMOS.

Abstract Interpersonal relationships are crucial for the growth and development of the organization as it directly or indirectly impacts employee performance. The present study aimed to develop an interpersonal relationship scale inventory for nurses, identifying the various dimensions of interpersonal relationships and validating the developed scale using EFA and CFA approaches. A methodological cross-sectional study design consisting of two phases was used. The study was conducted in government and private-sector hospitals. In the first phase, 250 nurses participated in the study, and 4 factors with 16 items were identified using EFA. In the second phase, confirmatory factor analysis was performed with a sample size of 766 nurses. Information related to factor loading (EFA), descriptive statistic, correlation matrix, standardized estimation in the CFA model, and discriminant validity were presented in tabular form. Data were analyzed using SPSS 22.0 and AMOS 23.0. The result indicated that the CFA model was ascertained by the following indices: CFI =0.973; GFI= 0.958; RMSEA= 0.048; TLI= 0.967; SRMR= 0.033. The results were within the acceptable range, indicating that the four factors obtained from EFA were validated, also the reliability and the discriminant validity of the model were established. Moreover, the study shows that the four factors identified were regarded as crucial element that supports the interpersonal relationship scale developed in the study. The four-factor scale can be used by nursing managers, and educators to understand the competencies of nurses towards people management, which have a significant impact on patient outcomes. Also, the scale would be helpful in assessing the effectiveness of the training program to measure the social skills and competencies of the nurses, hence there exist a significant implication of this study. The study concludes with the validation of the four-factor interpersonal relationship scale inventory which can be a useful tool to assess workplace relationships for healthcare professionals. As a future scope, the researcher can validate the scale using different sample frames.
