Influence of Employees’ Attitudinal Variables on Organizational Citizenship Behaviour and Organisational Commitment

This study investigates the influence of employees’ attitudinal variables (perceived organisational justice, organisational support, organisational attachment, and mental strain) on organizational citizenship behaviour and organisational commitment among employees in Nigerian private university. Ex-post facto research design was adopted. Non-proportional stratified and simple random sample techniques were used to select six hundred participants from different departments of Babcock University, Ilishan-Remo, Ogun State, Nigeria. Six self-report questionnaires were used to generate data. Two hypotheses were raised and answered using multiple regression (stepwise) and T-test statistics. Findings revealed among other, that the four predictor variables (perceived organisational justice, organisational support, organisational attachment, and mental strain) combined and individually predicted the criterion variables (organisational citizenship behaviour and organisational commitment). Based on the findings, the paper recommended among others, that employers’ of labour should pay great attention to factors that have significant effect on employees’ commitment; in this case, organisational commitment and organisational citizenship behaviour.
