Organizational Commitment Scale (OCS)

Abstract

The Organizational Commitment Scale (ISSP OC scale) is an economical, three-item measure developed to assess the affective facet of organizational commitment (OC), which captures an individual’s identification with and emotional involvement in their employer organization. This scale was first introduced in 1997 as part of the International Social Survey Programme (ISSP) and has since been translated into over 50 languages, with data available across 38 countries.

Psychometric evaluations using the ISSP 2015 data confirmed acceptable to good internal consistency (reliability) across most language versions, including German. Furthermore, analysis demonstrated evidence for content, convergent, divergent, and criterion-related validity. Critically for cross-cultural research, the scale achieved approximate scalar invariance across 32 countries, enabling researchers to confidently compare latent means, variances, and covariances of the OC construct globally. The scale’s brevity (less than one minute processing time) makes it highly efficient for large-scale, representative surveys.

Purpose

The primary purpose of the ISSP OC scale is to provide a brief and economical measure of organizational commitment for use in large-scale international surveys, particularly within the International Social Survey Programme (ISSP) Work Orientations module. Its three-item structure is designed for efficiency, making it suitable for inclusion in extensive questionnaires where minimizing respondent burden is crucial.

The scale is specifically intended for cross-cultural research, allowing investigators to examine work-related psychological constructs and organizational processes across diverse national contexts. It is highly applicable for researchers studying phenomena such as fluctuation (turnover intentions) and organizational citizenship behavior, offering insights valuable to both academic researchers and practitioners aiming to improve organizational outcomes.

Construct

The ISSP OC scale measures Organizational Commitment (OC), defined broadly as the strength of an individual’s identification with and involvement in a particular organization (Porter et al., 1974). More specifically, the ISSP scale focuses exclusively on the affective commitment facet. This facet represents an employee’s emotional attachment to, identification with, and involvement in the organization, often driven by a genuine desire to remain employed by the company.

This affective view aligns with the foundational definition proposed by Porter and colleagues, distinguishing it from other conceptualizations, such as the cognitive/calculative approach (Becker’s side-bet theory, 1960) or the normative component (Wiener & Vardi, 1980). Although the popular three-component model (Meyer & Allen, 1991) integrates these facets, empirical findings often highlight the superior predictive and concurrent validity of affective commitment across various job outcomes, justifying the ISSP scale’s focus on this single dimension.

Validity

The ISSP OC scale demonstrates robust validity across several dimensions, supported by analyses conducted using the ISSP 2015 data across 32 countries.

Content validity is assumed because the three items directly reflect the established definition of affective commitment, encompassing involvement, identification, and behavioral indicators of dedication to the organization’s success.

Evidence for convergent and criterion validity was established through the scale’s nomological network. Multilevel correlation analyses revealed strong positive associations with theoretically linked constructs, including occupational commitment (r = .53) and job satisfaction (r = .52). Moderate to strong positive correlations were also found with person-job fit (r = .34), promotion opportunities (r = .32), and organizational flexibility (r = .26). Furthermore, the scale showed expected negative correlations with adverse factors such as job stress (r = –.11), discrimination, and harassment.

Reliability

The reliability of the ISSP OC scale was assessed using internal consistency measures across the participating countries. The calculated values for Cronbach’s alpha ranged from .44 to .76, while McDonald’s omega ranged from .45 to .76, with an average omega of .69 across the 32 countries analyzed. While these raw figures suggest moderate reliability for a brief scale, they are generally considered acceptable for large-scale research instruments measuring a narrow construct.

To contextualize this brevity, researchers applied the Spearman-Brown prophecy formula to estimate the reliability if the scale were extended to the length of the traditional 15-item Organizational Commitment Questionnaire (OCQ). The corrected omega value of .92 indicates that the three items of the ISSP scale, despite their brevity, effectively tap into the construct of OC as reliably as the longer, conventionally used OCQ instrument (Mowday et al., 1979).

Factor Analysis

Factor analysis was crucial for validating the scale’s structure and its applicability across different cultures. Initially, Confirmatory Factor Analysis (CFA) was conducted by coupling the three ISSP OC items with two items measuring occupational commitment to achieve sufficient degrees of freedom for model evaluation. The results overwhelmingly supported a correlated two-factor model (OC and occupational commitment) over a single-factor model for 32 out of 38 countries, demonstrating the distinct nature of organizational commitment as measured by the ISSP items.

Crucially, testing for measurement invariance across the 32 accepted countries showed that strict scalar invariance did not hold when using conventional multi-group CFA methods. However, employing the alignment method revealed good approximate scalar invariance (R² = .984 for loadings and R² = .994 for intercepts). This strong approximate invariance confirms that the latent means, variances, and covariances of OC are comparable across these 32 diverse countries, validating its use in cross-cultural studies.

Further invariance testing comparing organizational employees (N = 20,640) and self/family business employees (N = 3,658) also supported partial strict invariance for the OC construct (when assuming essential tau-equivalence), confirming that the scale functions similarly across different employment relationships, although self/family employees showed a significantly higher latent mean level of OC.

Instrument

Test Type: Standardized, validated, self-report psychological scale (Affective Organizational Commitment)

Format: Three items measured on a 5-point Likert scale (1 = Strongly agree to 5 = Strongly disagree). The authors recommend inverting the scoring so that higher scores indicate higher OC.

Language Available: Translations exist in over 50 languages. These include, but are not limited to: Arabic, Chinese, Croatian, Czech, Danish, Dutch, English (Australia, Great Britain, Iceland, United States, New Zealand), Estonian, Finnish, French (Belgium, France), Georgian, German (Austria, Germany, Switzerland), Icelandic, Indian (11 different languages), Hebrew, Japanese, Latvian, Lithuanian, Norwegian, Philippine (6 different languages), Polish, Russian (Latvia, Russia, Israel), Slovakian, Slovenian, South African (6 different languages), Spanish (Chile, Mexico, Spain, Venezuela, United States), Surinamese, Swedish (Finland, Sweden), Taiwanese, and Turkish.

Population Group: Employees working for pay (organizational employees and self/family business employees).

Age Group: Generally 18 years and older (with minor variations in some countries, e.g., 15+ in Finland and Estonia).

Population Details: Data collection for psychometric evaluation utilized the ISSP 2015 survey, drawing a global sample of N = 26,100 (after filtering for complete data on OC items) from 38 countries. The sample demonstrated typical demographic diversity (51.54% male, mean age 42.88 years).

Test Methodology: The scale is administered via various survey modes, including face-to-face interviews (PAPI), computer-assisted interviews (CAPI, CASI), web questionnaires (CAWI), and telephone interviews. The processing time is highly economical, estimated at less than one minute.

Permissions & Fee and Test Year

The scale was first used in the ISSP Work Orientations module in 1997 and subsequently replicated in the 2005 and 2015 surveys. As the scale is integrated into the International Social Survey Programme, detailed information, including translations and data archives, is generally made available for academic research purposes via the ISSP website (http://www.issp.org/) and its data archive (http://dx.doi.org/10.4232/1.12848).

The scale is suitable for research applications but is explicitly noted as not suitable for individual diagnostics due to its relatively low reliability compared to longer diagnostic instruments.
