Study title

This is the R Code of the ZIS-documentation of the ISSP Organizational Commitment Scale ( https://doi.org/10.6102/zis312 ). It includes the cross-cultutral computation of descriptive statistics, reliability (Cronbach's alpha, McDonald's Omega and average variance extracted), factorial and convergent validity, and measurement invariance. Used methods were confirmatory factor analyses (factorial validity, reliability, measurement invariance), hierarchical linear modeling (convergent validity), and the alignment method of measurement invariance. Attached you find the abstract of the documentation: Organizational commitment (OC) refers to a person’s identification with and involvement in their company. The herein presented ISSP OC scale was used first in the International Social Survey Programme (ISSP) in 1997. It is an economic scale consisting of three items measuring the affective facet of organizational commitment. Translations exist in 50 languages, and data for 38 countries are available. The German-language version of the scale and most of the other language versions showed acceptable to good reliability (internal consistency). Using data of the ISSP 2015 ( https://doi.org/10.4232/1.12848 , https://doi.org/10.4232/1.13059 ), we found evidence for convergent, divergent, and criterion-related validity. The scale showed approximative scalar invariance across 32 countries which allows comparing latent variances, covariances, and means in cross-cultural studies.
