Abstract—Power can be envisaged as an individual potential to change, control or influence the behavior, attitudes, opinions, objectives, needs, and values of another party. The purpose of this study is to adapt and analyze the validity and reliability of Interpersonal Power, of a Malaysia version IPI(M)) as well as examine and develop the psychometric properties of the IPI(M) construct which integrates 5 subscales–reward, coercive, expert, referent and legitimate powers. A questionnaire survey was administered to 388 executives working directly under Human Resource Managers in the state-owned organization known as Government Link Companies (GLCs). Prior to that, an exploratory factor analysis (EFA) for pilot study was conducted on 44 items of IPI scale to explore the structure underlying the set of questions designed samples. EFA results confirmed the measurement scale in this study satisfactorily showed a five-factor structure: Reward, Coercive, Legitimate, Expert, and Referent with 25 items remained. Then a confirmatory factor analysis (CFA) was initially conducted on the 25 items of IPI(M) scale to access the quality of the factor structure by statistically testing the significance of the overall model of to access the goodness-of-fit of the new measure construct. The CFA results confirmed that the measurement scale used in this study satisfactorily met the standards of validity and reliability analysis and showed acceptable internal consistency reliability for the overall and the five specific subscales of power factor. The IPI(M) construct provides a multi-dimensional assessment tool to diagnose and guide leader social power in the Malaysian organizational context.
