    Measurement of Organizational Citizenship Behaviour; Reliability and Validity in Sri Lankan Context
    (Department of Human Resource Management, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka, 2018) Janadari, M. P. N.; Sri Ramalu, S.; Wei, C. C.
    This paper investigates the goodness of the measure of organizational citizenship behaviour in terms of reliability and validity. Organizational Citizenship Behaviour considers as the extra role or voluntary behaviour not directly or explicitly recognized by the formal reward system, and that in the aggregate it promotes the effective functioning of the organization. However, more research studies on OCB focus on western context while similar effort in Sri Lankan context rather scant. Data were gathered through the survey by distributing structured questionnaire from public sector organizations. As per the discussion basically, two main criteria called reliability and validity have to be achieved to confirm the goodness of the measure. Internal reliability and composite reliability scales were commonly employed to asses construct reliability of the intended constructs. However, convergent validity achieved through Average Variance Extracted (AVE) and factor loadings. Discriminant validity can be evaluated by assessing the cross loadings among constructs, Fornel-Larcker criterion, and Heterotrait- Monotrait Ratio of correlation (HTMT). According to the derived outcomes implications regarding the goodness of measure were discussed and revisions of measurement in Sri Lankan context were presented.

    Psychometric Properties of Reflective Constructs; Psychological Capital and Organizational Citizenship Behavior towards the Environment
    (9th International Conference on Business and Information (ICBI-2018), Department of Management Studies and Toc H Institute of Science and Technology, India, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka, 2018) Janadari, M.P.N.; Subramaniam s/o Sri Ramalu; Wei, C.C.
    As an outgrowth of the extended seminal works much of the scholarly concentration focus on the positive psychology of the work place or positive organizational behaviour. Consequently, attention was drawn on psychological movements at the macro or organizational level and individual movements less examined though it improves the efficiency and the effectiveness of the organization. Likewise, more research studies on psychological capital and organizational Citizenship Behaviour towards environment (OCBE) centred on western context and the testing of the goodness of measure of these variables in Sri Lankan context relatively scant. Therefore, the general objective of this paper is to validate the conceptualization of psychological capital and OCBE in Sri Lankan Context. Data were collected through the survey method by using adapted questionnaires from 196 public sector utility employees in Sri Lanka. As per the discussion mainly, two core criteria were employed as reliability and validity to confirm the goodness of the measures of the constructs. Internal reliability and composite reliability scales were commonly work out to assessed construct reliability of the intended constructs. Convergent validity achieved through Average Variance Extracted and factor loadings. Discriminant validity evaluated by assessing the cross loadings, Fornel-Larcker criterion, and Heterotrait- Monotrait Ratio of correlation (HTMT). All validity and reliability indicators including items’ loadings, composite reliability, and average variance extracted (AVE), and square roots of the AVE and HTMT correlations have demonstrated higher coefficients confirming the reliability and validity of the study constructs. Therefore, findings demonstrated that the psychological capital and OCBE constructs could be used for potential researchers in Sri Lankan context for their future studies. The PLS 03 data analysis technique added more value in this study providing significant contribution theoretically and methodologically by validating and conceptualizing the concepts
