Development and Validation of Work Place Integrity Scale; Evidence from Ghana.

Abstract

This article developed and validated work place integrity scale that are applicable across industries. Responded questionnaire perceived to contribute to integrity were subjected to principal components analysis. Overall Cronbach’s alpha coefficient of 0.843 was reported. The Kaiser-Meyer-Olkin value was 0.887, whiles the Bartlett’s Test of Sphericity reached statistical significance, supporting the use of factor analysis. Total variance explained initially, revealed the presence of six components with eigenvalues 24.973%, 8.309%, 5.045%, 4.843%, 4.077%, 3.969% of the variance respectively contributing to a cumulative variance of 51.2%. Using Cattell’s scree test, it was decided to retain components 1&2 for further investigation. To aid in the interpretation of these two components, oblimin rotation was performed which resulted in a simple pattern matrix with 2 components showing a number of strong loadings. The resulted component correlation matrix was very strong (0.346). The two-component solution explained a total of 33.2% of the variance, with Component 1 contributing 24.9% and Component 2 contributing 8.3%. The resulted pattern matrix relating to component 1 supports the non- usage of inducement to assess the integrity of a person, whiles component 2 support the use of inducement to assess the integrity of a person.
