General Company Commitment (Garbarino) (GCCG)

1. Abstract

The General Company Commitment scale—frequently designated in psychometric and relationship marketing literature as the GCCG—was developed and empirically validated by Ellen Garbarino and Mark S. Johnson in their seminal 1999 study, “The Different Roles of Satisfaction, Trust, and Commitment in Customer Relationships”, published in the Journal of Marketing. Designed to assess an individual consumer’s psychological pledge, affective attachment, and relational dedication toward an organization, the instrument operationalizes customer commitment beyond basic repeat-purchase metrics. The GCCG consists of 5 items evaluated on an 8-point Likert-type scale, capturing five core relational facets: institutional pride, sense of belonging, long-term care for organizational success, self-perceived loyalty, and explicit dedication to maintaining an ongoing commercial and relational partnership.

Psychometrically, the GCCG represents a unidimensional, highly reliable construct demonstrating exceptional internal consistency, with Cronbach’s alpha coefficients consistently ranging between .85 and .91 across diverse consumer groups. Confirmatory factor analyses (CFA) reveal standard factor loadings exceeding .72 for all five indicators, confirming robust convergent validity and an Average Variance Extracted (AVE) surpassing the recommended .50 benchmark. The scale holds pivotal structural significance in the dual-pathway model of relationship marketing, serving as an indispensable central mediator between customer trust and future behavioral intentions for relational customers, while proving distinct from transactional customer evaluations dominated by overall satisfaction. The instrument offers critical utility for consumer psychologists, service management scholars, and marketing practitioners evaluating organizational identification, brand equity, and customer lifetime value.

4. Purpose

The primary purpose of the General Company Commitment scale is to provide a reliable, psychometrically rigorous, and parsimonious instrument capable of measuring the strength of a consumer’s psychological attachment and enduring relational pledge toward a commercial or non-profit organization. Prior to the late 1990s, the predominant paradigm in consumer marketing treated customer satisfaction as the primary, and often sole, universal driver of customer retention and future purchase intentions. However, empirical inconsistencies emerged wherein highly satisfied customers frequently exhibited brand-switching behavior, while customers facing service delivery lapses remained staunchly loyal. Garbarino and Johnson conceived the GCCG to resolve this theoretical anomaly by operationalizing the deep, affective, and cognitive bonds that characterize relational exchange.

Specifically, the GCCG measures why and to what extent customers transcend transactional calculus (i.e., immediate price-to-quality evaluations) and transition into a psychological state of mutual interdependence. The theoretical rationale posits that while transactional customers navigate marketplace decisions through episodic cognitive appraisals of service satisfaction, relational customers view their interactions through the prism of an ongoing partnership. In this relational state, commitment acts as a stabilizing psychological anchor that insulates the consumer-organization dynamic against transient service failures, competitive promotions, and market fluctuations.

In research contexts, the scale is employed within structural equation modeling (SEM) frameworks to examine customer relationship trajectories, brand community dynamics, subscriber behaviors, and service relationship longevity. It enables researchers to segment consumer populations based on psychological attachment rather than purely behavioral frequency metrics. In managerial and clinical consulting applications, the GCCG functions as a diagnostic tool to audit customer equity, predict long-term contract renewal, assess subscription vulnerability, identify brand evangelists, and gauge the efficacy of customer relationship management (CRM) interventions intended to foster emotional brand loyalty.

5. Psychological Construct

The psychological construct measured by the GCCG is customer commitment, conceptualized in social psychology and organizational behavior as an enduring desire to maintain a valued relationship. Unlike behavioral loyalty, which merely tracks repeat purchasing habits (and can stem from inertia, high switching costs, or monopolistic conditions), psychological commitment represents an internal affective, moral, and cognitive orientation. The GCCG captures five key psychological facets integrated into a unified construct:

5.1. Organizational Pride

Pride reflects the positive emotional valence and self-enhancement an individual derives from being publicly or privately associated with an organization. Rooted in social identity theory, this dimension captures how the consumer internalizes the organization’s reputation, artistic excellence, social prestige, or ethical values into their own self-concept. When a customer feels proud to be affiliated with a company, the relationship elevates their self-esteem, transforming consumption into an identity-affirming act.

5.2. Psychological Belonging

The sense of belonging taps the fundamental human need for relatedness, community, and social inclusion. Within the GCCG, belonging shifts the customer’s self-perception from an external, arm’s-length “buyer” to an internal “member” or “insider.” This feeling of inclusion fosters emotional warmth, perceived kinship with staff and fellow patrons, and a subjective stake in the organizational culture.

5.3. Altruistic / Long-Term Success Orientation

This facet assesses the degree to which a consumer transcends self-interested utility optimization to genuinely care about the ongoing health, survival, and prosperity of the company. Unlike purely transactional consumers who focus exclusively on “what have you done for me lately,” committed consumers demonstrate benevolent concern for the firm’s longevity. They are willing to invest personal resources, tolerate necessary price increases, or provide constructive feedback because they view the organization’s survival as mutually beneficial.

5.4. Self-Identified Loyalty

This dimension operationalizes the consumer’s subjective cognitive affirmation of themselves as a “loyal customer.” It captures an intentional self-categorization that guides behavioral consistency. By acknowledging personal loyalty, consumers engage in self-regulatory mechanisms that actively resist competitive overtures, ignore marketing counter-attractions, and maintain cognitive alignment with their stated loyalty identity.

5.5. Relationship Maintenance Intentions

The final component captures an explicit, forward-looking dedication to sustain the commercial and relational bond across indefinite future time horizons. This reflects the conative or intentional component of commitment, translating affective sentiments and cognitive pride into a definitive willingness to invest effort, time, and financial capital to perpetuate the partnership over time.

6. Theoretical Framework

The General Company Commitment scale is anchored in several foundational theories from relationship marketing, consumer psychology, and social exchange theory:

6.1. The Commitment-Trust Theory of Relationship Marketing

The primary theoretical foundation of the GCCG is the Commitment-Trust Theory articulated by Morgan and Hunt (1994). This paradigm posits that relational commitment and trust are the essential twin mediating variables that distinguish successful relationship marketing from transactional exchange. Rather than viewing customer behavior as a series of isolated economic events, Morgan and Hunt argued that commitment is the central variable that produces cooperative behaviors, minimizes relational risk, and induces customers to reject short-term alternative gains in favor of the expected long-term benefits of staying with an established partner. Garbarino and Johnson operationalized this perspective by designing the GCCG to measure the commitment node within this theoretical network.

6.2. Social Exchange Theory and Psychological Contracts

The scale draws heavily on Social Exchange Theory (Homans, 1958; Blau, 1964; Thibaut & Kelley, 1959). In social exchange frameworks, interpersonal and institutional relationships evolve through reciprocal, mutually rewarding interactions over time. As relationships mature, economic contracts (explicit exchanges of money for goods) are supplemented or superseded by psychological contracts characterized by unwritten expectations of loyalty, goodwill, and mutual support. The GCCG captures this psychological elevation, wherein interactions become governed by mutual norms of reciprocity rather than strict economic parity.

6.3. The Dual-Pathway Relational Continuum Model

The foundational assumption of Garbarino and Johnson’s (1999) conceptual framework is that customers exist along a continuum ranging from purely transactional orientations (low relational focus) to deeply relational orientations (high relational focus). In transactional encounters, customers focus on discrete service encounters, and their overall satisfaction directly governs their future intentions. Conversely, in relational encounters—such as theater subscribers, long-term bank patrons, or healthcare clients—overall satisfaction is merely an antecedent input. Instead, trust and commitment completely mediate the relationship between satisfaction and future behavioral intentions. The GCCG serves as the operational mechanism capturing the emotional and structural commitment in this advanced relational pathway.

7. Validity

The GCCG has undergone rigorous empirical validation across multiple consumer cohorts, demonstrating robust construct, convergent, discriminant, and nomological validity.

7.1. Construct and Convergent Validity

Garbarino and Johnson (1999) validated the GCCG using a sample of 1,511 off-Broadway repertory theater patrons, segmented into individual ticket buyers (transactional cohort) and long-term subscribers (relational cohort). In structural equation modeling, all five items exhibited high, statistically significant factor loadings on the single latent commitment construct (p < .001). Standardized factor loadings ranged from .72 to .88, comfortably exceeding the standard .50 threshold. The Average Variance Extracted (AVE) for the commitment construct exceeded .65 across both samples, demonstrating that the latent construct accounts for the vast majority of variance in its observed indicators, thus confirming convergent validity.

7.2. Discriminant Validity

A critical psychometric hurdle in relationship marketing research involves proving that customer commitment is empirically distinguishable from trust and overall satisfaction. Garbarino and Johnson performed rigorous discriminant validity assessments using nested model chi-square difference tests. The correlation between latent commitment and latent trust was estimated freely, and then constrained to unity (1.00). The unconstrained model yielded a significantly superior fit across both transactional (Δχ² = 412.3, df = 1, p < .001) and relational cohorts (Δχ² = 589.6, df = 1, p < .001). Furthermore, applying the Fornell-Larcker criterion, the square root of the AVE for commitment exceeded all inter-construct correlations with satisfaction and trust, proving that the GCCG represents a unique psychological domain.

7.3. Predictive and Nomological Validity

Nomological validity was confirmed by embedding the GCCG within a comprehensive structural equation model predicting objective and subjective customer outcomes. For relational customers, commitment exerted a substantial direct effect on future subscription renewal intentions (β = .51, p < .001), willingness to recommend the organization to peers (β = .44, p < .001), and voluntary financial donation behavior (β = .38, p < .001). Importantly, while overall satisfaction failed to predict future intentions directly for high-relational subscribers, commitment fully mediated these relationships, confirming its theoretical role as the ultimate behavioral driver in established partnerships.

8. Reliability

The reliability of the GCCG has been established through internal consistency estimates, composite reliability metrics, and cross-sample replications:

8.1. Internal Consistency

In the original validation study by Garbarino and Johnson (1999), the scale exhibited high internal consistency across distinct consumer segments:

• Transactional Segment (Individual Ticket Buyers, n = 783): Cronbach’s alpha (α) = .85
• Relational Segment (Subscribers, n = 728): Cronbach’s alpha (α) = .91
• Aggregated Sample: Cronbach’s alpha (α) = .89

Subsequent independent studies in diverse domains—such as retail banking, telecommunications, professional sports fandom, and healthcare services—have consistently replicated alpha coefficients ranging between .84 and .93, consistently surpassing the conventional .70 threshold for exploratory research and the .80 standard for basic research.

8.2. Composite Reliability and Variance Metrics

Because Cronbach’s alpha can suffer from biases related to tau-equivalence assumptions, structural modeling researchers calculated Composite Reliability (Raykov’s rho / McDonald’s omega). Across both cohorts, composite reliability was established at .90 for subscribers and .86 for non-subscribers, demonstrating that measurement error across the five indicators is minimal. Item-total correlations for all five items routinely exceed .60, with no single item’s deletion leading to an improvement in the overall reliability coefficient.

9. Factor Analysis

The factor structure of the GCCG was rigorously tested using both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) within a structural equation modeling environment using LISREL and maximum likelihood estimation.

9.1. Factor Structure and Loadings

Both EFA (using principal axis factoring with promax rotation) and CFA confirmed a strictly unidimensional (single-factor) structure. All five items load strongly and exclusively onto a single commitment factor, with eigenvalues exceeding 3.5 and accounting for more than 68% of the total variance across items. The standardized CFA factor loadings (λ) reported in empirical testing are summarized below:

9.2. Model Fit Indices

In the measurement models tested by Garbarino and Johnson (which simultaneously modeled commitment, trust, satisfaction, and future intentions), the global goodness-of-fit indices demonstrated excellent concordance with empirical data:

• Goodness-of-Fit Index (GFI): .94
• Adjusted Goodness-of-Fit Index (AGFI): .91
• Comparative Fit Index (CFI): .96
• Root Mean Square Error of Approximation (RMSEA): .048 (90% CI: [.039, .057])
• Standardized Root Mean Square Residual (SRMR): .039

Multi-group CFA demonstrated metric invariance (equal factor loadings across transactional and relational groups), confirming that the construct has the same substantive meaning across consumer cohorts with varying contact frequency.

10. Instrument / Measurement Tool

The operational features and administration guidelines of the General Company Commitment scale are structured as follows:

• Construct Measured: Unidimensional General Customer Commitment (affective pride, belonging, benevolent care, self-perceived loyalty, and relationship maintenance intentions).
• Instrument Type: Self-report paper-and-pencil or computer-assisted personal/web survey (CAWI).
• Item Count: 5 items.
• Target Population: Consumers, subscribers, patrons, clients, or members of commercial and non-profit organizations.
• Response Scale: 8-point Likert-type scale ranging from 1 (“Strongly Disagree”) to 8 (“Strongly Agree”). (Note: Many subsequent marketing studies adapt the format to a 7-point Likert scale without loss of psychometric properties).
• Administration Time: Approximately 1 to 2 minutes.
• Reverse-Coded Items: None; all five items are positively worded.
• Scoring Protocol: A composite commitment index is generated by calculating the arithmetic mean of the five items. Alternatively, in structural equation modeling, the five items are treated as continuous indicators of a latent commitment variable. Higher aggregate scores indicate stronger psychological commitment and greater relationship depth.
