Organizational citizenship behavior: the psychometric properties of the questionnaire

The study was carried out in a sample of 289 employees from a number of Lithuanian organizations (22.1% of male, 77.9% of females; mean age 32.32 years). To identify the dimensionality of OCB, an exploratory factor analysis was conducted. Next, after conducting the item analysis, 29 items were retained and repeatedly factor-analyzed. The results have revealed five OCB dimensions: altruism, courtesy, civic virtue, conscientiousness, and initiative. An overall questionnaire and all its subscales have proven to have high reliability coefficients (Cronbach alphas > 0.76). Moreover, the analysis has shown that the distinguished OCB dimensions were separable from in-role performance and correlated to a number of factors reported as the most common OCB correlates (e.g., organizational identity, commitment, and job satisfaction). To generalize, preliminary findings strongly suggest that the Lithuanian version of the OCB questionnaire, developed in this study, has adequate psychometric properties and is congruent to the classical concept of OCB. Naturally, in the future, additional empirical evidence will be necessary to support the identified OCB factor structure
