Abstract:
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
