B2B Decision-making Styles Scale

1. Abstract

The B2B Decision-making Styles Scale (B2B-DMSS) is an empirical psychometric instrument developed by Hendrik Godbersen and Vanessa Gully to evaluate, categorize, and quantify organizational procurement orientations within business-to-business (B2B) markets. Departing from traditional industrial marketing frameworks that rely almost exclusively on macro-environmental and firmographic determinants—such as geographic location, enterprise size, annual turnover, and formal operational structure—the B2B-DMSS adapts validated cognitive and behavioral paradigms from consumer decision theory to the complex, collective environment of organizational buying centers. Specifically grounded in the foundational Consumer Styles Inventory (CSI) established by Sproles and Kendall (1986), the scale conceptualizes procurement not as a purely rational algorithmic process, but as a boundedly rational, psychologically anchored organizational posture.

The finalized measurement tool comprises 26 self-report items operationalizing seven distinct procurement decision-making dimensions: (1) Perfectionistic and Quality Conscious Buyer (PQCB; 6 items), (2) Confused and Poorly Informed Buyer (CPIB; 5 items), (3) Fast and Careless Buyer (FCB; 5 items), (4) Novelty and Innovation Seeking Buyer (NISB; 3 items), (5) Habitual and Loyal Buyer (HLB; 3 items), (6) Price Conscious Buyer (PCB; 2 items), and (7) Brand and Reputation Conscious Buyer (BRCB; 2 items). Respondents evaluate statements using a six-point Likert-type rating scale ranging from 1 (completely disagree) to 6 (completely agree), or alternatively along a continuous 0–100 visual analogue rating format. Psychometric validation utilizing partial least squares path modeling (PLS-PM) and principal component analysis (PCA) confirms robust construct integrity. Scale reliability demonstrates internal consistency values spanning Dillon-Goldstein’s rho (composite reliability) from .81 to .91, and Cronbach’s alpha values ranging from .57 to .88. Criterion and predictive validity are supported through significant hypothesized associations with organizational supplier expectations regarding service quality, absolute price levels, price-performance value, and billing transparency. The instrument provides industrial psychologists, procurement consultants, and B2B marketers with an empirically rigorous tool for behavioral market segmentation, vendor alignment, and buying center diagnostics.

4. Purpose

The primary purpose of the B2B Decision-making Styles Scale (B2B-DMSS) is to diagnose, profile, and systematically quantify the underlying behavioral and cognitive orientations that guide organizations during supplier evaluation, negotiations, and product or service acquisition. For decades, the dominant paradigms in industrial buying behavior—originating from the seminal models of Webster and Wind (1972) as well as Jagdish Sheth (1973)—posited that business procurement is an inherently detached, strictly hyper-rational calculation driven solely by total cost of ownership, technical specifications, and logistical delivery capabilities. Consequently, traditional B2B market segmentation models have concentrated heavily on observable “hard firmographics” (e.g., standard industrial classification codes, geographic perimeter, revenue brackets, and headcount).

However, contemporary empirical findings demonstrate that firmographics possess limited predictive power regarding how buying centers actually process ambiguous supplier information, handle technological disruptions, mitigate operational risk, or resolve internal trade-offs between pricing and performance. Individual purchasing agents, committee chairpersons, and executive buying groups exhibit pronounced cognitive biases, heuristic decision rules, and habitual patterns. The B2B-DMSS bridges this critical empirical divide by providing a standardized, psychometrically validated inventory that captures organizational decision-making styles as collective behavioral tendencies.

Research and Theoretical Applications

In academic research, the B2B-DMSS serves as a foundational instrument for testing hypotheses situated at the intersection of organizational behavior, micro-foundations of supply chain management, and industrial buyer psychology. Researchers utilize the scale to:

• Investigate how psychological purchasing orientations moderate the relationship between supplier value propositions and customer lifetime value.
• Examine organizational resilience and adaptability during macro-economic supply shocks by contrasting conservative, habitual styles against agile, novelty-seeking profiles.
• Evaluate the cross-cultural invariance of purchasing styles across diverse geopolitical markets, assessing whether multinational buying centers maintain standardized styles across regional subsidiaries.
• Advance behavioral agency theory within corporate governance by quantifying how agency conflicts between purchasing agents and executive boards manifest in careless or confused procurement strategies.

Practical and Diagnostic Applications

In applied corporate settings, the B2B-DMSS functions as both an internal diagnostic tool for buying organizations and an external behavioral segmentation instrument for business-to-business vendors:

• Internal Buying Center Audit: Organizations deploy the scale to audit their own procurement governance. Identifying high scores on maladaptive dimensions—such as the Confused and Poorly Informed or Fast and Careless subscales—enables Chief Procurement Officers (CPOs) to pinpoint structural vulnerabilities, implement cognitive de-biasing protocols, streamline internal communication channels, and restructure request-for-proposal (RFP) procedures.
• Strategic Vendor Alignment and Marketing Segmentation: For supplying enterprises, standard demographic segmentation often fails to illuminate why prospective accounts reject proposals. By administering the B2B-DMSS to prospective or active accounts, vendors can dynamically tailor their sales messaging, contract structures, and service packages. For instance, when pitching to an organization characterized by a Perfectionistic and Quality Conscious style, vendors must provide extensive engineering documentation, certifications, and high-touch technical proof-of-concept trials. Conversely, when engaging a Brand and Reputation Conscious client, marketing communications should emphasize industry leadership, client pedigree, and social proof.

5. Psychological Construct

The construct measured by the B2B-DMSS is defined as the enduring, patterned cognitive, emotional, and behavioral orientation that an enterprise and its collective buying center exhibit when evaluating options, managing market information, and finalizing vendor transactions. Rather than viewing procurement as a static series of mechanical stages, the B2B-DMSS conceptualizes decision styles as multidimensional, non-mutually exclusive organizational traits. An organization may simultaneously exhibit moderate price consciousness alongside strong brand reliance or high quality demands. The scale operationalizes this construct across seven comprehensive subscales:

1. Perfectionistic and Quality Conscious Buyer (PQCB)

The PQCB dimension captures an organizational orientation characterized by an uncompromising search for technical excellence, optimal performance, and superior product specifications. Enterprises scoring high on PQCB perceive procurement as an essential contributor to their own competitive differentiation. Consequently, buying agents allocate substantial cognitive effort, time, and budgetary resources to comprehensive due diligence, testing protocols, and rigorous supplier audits. They operate under elevated expectations, systematically eliminating “satisfactory” or average alternatives from consideration. For example, an advanced aerospace manufacturer vetting specialty alloy suppliers will conduct extensive metallurgical audits and tolerate elongated lead times to ensure zero-defect production materials.

2. Confused and Poorly Informed Buyer (CPIB)

The CPIB dimension reflects systemic information overload, cognitive strain, and uncertainty within the procurement unit. This style emerges when an enterprise is inundated by competing technical data, excessive product claims, and a hyper-fragmented vendor marketplace, yet lacks the internal expertise or analytical architecture to evaluate these inputs objectively. Procurement agents within high-CPIB organizations experience chronic hesitation, ambiguous choice paralysis, and decision-making insecurity. Lacking credible internal data evaluation mechanisms, they frequently resort to superficial cues, such as supplier advertising frequency, as an informational surrogate to resolve paralysis. An example is a non-technical small-to-medium enterprise attempting to procure enterprise resource planning (ERP) software, becoming completely incapacitated by overlapping feature lists and aggressive vendor promotional campaigns.

3. Fast and Careless Buyer (FCB)

The FCB dimension denotes a procurement posture characterized by impulsivity, bounded temporal investment, lack of deliberate planning, and low cognitive engagement. High-FCB organizations operate under satisficing heuristics taken to an extreme: buying agents purchase the first readily available solution that meets minimal acceptable thresholds without conducting competitive benchmarking. Procurement is viewed as an administrative chore rather than a strategic value-driver. Consequently, these firms frequently suffer from post-purchase cognitive dissonance, contract disputes, and buyer remorse when unexpected operational defects or pricing discrepancies surface. A typical scenario involves a decentralized branch office purchasing maintenance services via unvetted local contractors without executing service-level agreements (SLAs), leading to costly subsequent operational disruptions.

4. Novelty and Innovation Seeking Buyer (NISB)

The NISB dimension identifies an aggressive organizational inclination toward technological novelty, cutting-edge market entries, and disruptive solutions. Organizations embodying this style prioritize being early adopters; their procurement criteria favor radical technological capabilities over established stability. High-NISB buying centers maintain active market intelligence pipelines to monitor emergent patents, novel manufacturing techniques, and next-generation software platforms, routinely reallocating working capital to refresh inventory with state-of-the-art offerings. For instance, a venture-backed artificial intelligence startup will deliberately select prototype-stage semiconductor hardware to maintain a computational advantage over competitors, accepting moderate developmental volatility in exchange for market leadership.

5. Habitual and Loyal Buyer (HLB)

The HLB dimension captures deep relational inertia, vendor fidelity, and behavioral continuity. Enterprises scoring high on this subscale favor established partnerships, recurrently renewing contracts with existing vendors to minimize relational risk and administrative friction. Procurement routines are institutionalized: once a supplier demonstrates acceptable baseline compliance, the buying center erects high psychological and operational switching barriers, showing extreme reluctance to test alternative market offerings. An example includes an industrial packaging facility that has procured raw corrugated materials from the same regional supplier for two decades, relying on established personal relationships and predictable transactional routines rather than continuously bidding out contracts.

6. Price Conscious Buyer (PCB)

The PCB dimension reflects an organizational focus on fiscal discipline, strict expenditure monitoring, and aggressive pursuit of maximum short-term financial return per unit spent (value for money). Unlike careless buyers who purchase low-cost items arbitrarily, high-PCB firms commit dedicated analytical resources to cost-breakdown analyses, reverse auctions, and strict margin benchmarking. While they actively seek out lowest-cost alternatives, they operate with a clear understanding of minimum functional utility, ensuring that cost reduction does not completely compromise operational capability. A representative example is a high-volume contract manufacturer operating on razor-thin operating margins that mandates continuous cost audits and requires three competing bids for every standard operational purchase.

7. Brand and Reputation Conscious Buyer (BRCB)

The BRCB dimension operationalizes the extent to which an organization utilizes corporate prestige, global brand equity, and market prominence as its primary proxy for purchase security. Rather than investing substantial organizational capital into exhaustive direct product testing, high-BRCB firms limit their consideration sets strictly to premier, market-leading corporate entities (e.g., Tier-1 global vendors). This posture is frequently adopted as an institutional risk mitigation strategy—encapsulated by the historical industry adage, “Nobody ever got fired for buying IBM.” Pricing considerations become secondary, as the buyer is willing to pay a substantial brand premium to obtain external stakeholder legitimacy, board-level defensibility, and perceived operational security.

6. Theoretical Framework

The theoretical foundation of the B2B-DMSS synthesizes principles from cognitive psychology, organizational decision theory, and microeconomic behavior. Specifically, the scale represents an epistemological translation of individual consumer psychometrics into the collective, socio-technical domain of business procurement.

The Consumer Styles Inventory (CSI) Precedent

The structural architecture of the B2B-DMSS originates directly from the seminal work of Sproles and Kendall (1986), who developed the Consumer Styles Inventory (CSI). Sproles and Kendall conceptualized consumer decision-making styles as a mental orientation characterizing an individual’s approach to making consumer choices, identifying eight primary consumer personality styles: perfectionism/high-quality consciousness, brand consciousness, novelty-fashion consciousness, recreational/hedonistic shopping consciousness, price-value consciousness, impulsiveness/carelessness, confused by overchoice, and brand-loyal/habitual buying.

Godbersen and Gully recognized that while procurement professionals represent institutional entities, their cognitive architectures are constrained by the same underlying decision dynamics that govern individual consumers. However, direct wholesale importation of consumer instruments into industrial environments is theoretically invalid without contextual adaptation. Most notably, Godbersen and Gully deliberately removed the “recreational, hedonistic consumer” dimension. In organizational buying, transactions are executed on behalf of a corporate principal to fulfill functional operational objectives. Procurement agents do not allocate organizational capital for immediate personal hedonic entertainment or leisure enjoyment. The remaining seven dimensions were systematically restructured, shifting the referent from individual subjective feelings (“me / I”) to collective organizational practices, formal processes, and buying center expectations (“my company / our buying agents”).

Bounded Rationality and Heuristic Decision-Making

The conceptual legitimacy of the B2B-DMSS is firmly rooted in Herbert A. Simon’s theory of bounded rationality (Simon, 1957; 1979). Neoclassical economic theory posited that institutional buyers operate with complete information, infinite computational capacity, and purely objective utility-maximizing functions. Simon dismantled this assumption by demonstrating that human decision-makers within organizations are constrained by cognitive limitations, information asymmetry, temporal urgency, and ambiguous risk profiles. Consequently, buying centers do not optimize; they employ heuristics and engage in satisficing.

The B2B-DMSS subscales directly reflect specific bounded rationality configurations:

• The Satisficing vs. Maximizing Continuum: The Perfectionistic and Quality Conscious style represents an organizational maximizing heuristic, attempting to overcome bounded rationality through exhaustive data synthesis. In contrast, the Fast and Careless style reflects an extreme, poorly calibrated satisficing heuristic, seizing upon the first minimally acceptable option to truncate cognitive strain.
• Information Processing Under Overchoice: Grounded in choice overload theory (Schwartz, 2004), the Confused and Poorly Informed dimension captures the breakdown of organizational cognitive capacity when market entropy outpaces analytical bandwidth.
• Surrogate Heuristics: The Brand and Reputation Conscious and Habitual and Loyal styles operationalize trust and authority heuristics. When independent technical verification is cost-prohibitive or uncertain, corporate reputation and previous operational familiarity function as cognitive substitutes for complete information, minimizing transaction costs (Williamson, 1981).

Organizational Buying Center Dynamics

The theoretical model also integrates the classic industrial buying frameworks of Webster and Wind (1972) and Sheth (1973). These frameworks establish that industrial buying behavior is a multi-person, multi-phase decision process embedded within an organizational environment. Godbersen and Gully’s scale captures this shared organizational climate. By asking key informants within the buying center to report on the overarching practices of “my company,” the B2B-DMSS captures the institutionalized norms, procedural policies, and collective cognitive shortcuts that emerge from multi-stakeholder interactions among purchasing managers, technical engineers, finance directors, and executive leadership.

7. Validity

The psychometric validation of the B2B-DMSS was conducted using empirical field data obtained from an international sample of $N = 314$ procurement professionals and buying center agents. The sample was drawn from diverse geographical regions, including Europe (40.13%), Latin America (23.89%), Asia (14.33%), North America (14.01%), the Middle East (4.78%), Africa (1.91%), and Australia/Oceania (0.96%). A total of 53.19% of participating enterprises had an international operational scope, and 55.73% employed 250 or more personnel, establishing broad organizational representativeness. Structural equation modeling via Partial Least Squares Path Modeling (PLS-PM) in R was utilized to evaluate validity parameters.

Content Validity

Content validity was established through systematic conceptual mapping from the validated Consumer Styles Inventory (CSI). The original 40 CSI items were vetted by industrial marketing experts. The five items measuring hedonic/recreational purchasing were removed due to lack of B2B face validity. The remaining 35 candidate items were reformulated to reflect corporate purchasing realities and buying center terminology. Subsequent iterative pilot reviews ensured that all operationalized statements clearly reflected typical procurement challenges, contract evaluations, and vendor management practices.

Construct and Discriminant Validity

Construct validity was confirmed through item-construct loading evaluations and cross-loading matrices generated via PLS-PM:

• Convergent Validity: All 26 retained items demonstrated high factor loadings on their intended latent constructs, with the majority exceeding the rigorous .70 benchmark and no item falling below .60. Loadings ranged from .60 (item 9: CPIB) to .96 (item 26: BRCB). In the two-item PCB dimension, loadings reached .92 and .91, indicating excellent latent construct capture.
• Discriminant Validity: Discriminant validity was substantiated by examining the cross-loading matrix. Every individual item loaded substantially higher on its assigned theoretical construct than on any other latent construct (cross-loadings were consistently lower by a wide margin). For example, while item 1 (“Procuring very good quality is very important for my company”) loaded at .79 on PQCB, its cross-loadings across all other six latent constructs ranged from -.22 to .35. Similarly, item 26 loaded at .96 on BRCB, while its cross-loadings across other dimensions remained between -.05 and .36.

Criterion and Predictive Validity

Predictive and criterion-related validity were evaluated by testing structural hypotheses linking the seven B2B decision-making styles to enterprise-level expectations regarding four primary supplier performance dimensions: Service Quality, Price Level, Price Value, and Price Transparency. The empirical results demonstrated strong nomological network alignment:

• Expectations on Service Quality: Positively predicted by the Perfectionistic and Quality Conscious style ($eta > 0$), and negatively predicted by the Confused and Poorly Informed and Fast and Careless styles ($eta < 0$). Buyers striving for perfection demand rigorous technical and after-sales support, whereas careless or overwhelmed firms fail to articulate or demand structured service-level standards.
• Expectations on Absolute Price Level: Showed statistically significant positive associations with the Confused and Poorly Informed, Fast and Careless, Habitual and Loyal, and Price Conscious styles. Confused and careless buyers often encounter unmanaged price escalations due to lack of market benchmarking, while price-conscious buyers explicitly scrutinize base pricing.
• Expectations on Price Value (Cost-Benefit Balance): Positively influenced by the Perfectionistic and Quality Conscious, Habitual and Loyal, and Price Conscious styles, while being negatively affected by the Confused and Poorly Informed style, demonstrating that confused procurement units struggle to discern whether an offer delivers fair value relative to cost.
• Expectations on Price Transparency: Positively driven by the Perfectionistic and Quality Conscious, Habitual and Loyal, and Price Conscious styles, but significantly impaired by the Confused and Poorly Informed orientation. Transparent cost structures are highly valued by analytical and loyal buyers seeking sustainable partnerships, whereas information-overloaded buyers are hindered from effectively demanding detailed pricing breakdowns.

8. Reliability

The reliability of the B2B-DMSS was evaluated across its seven subscales using both classical internal consistency indices and modern structural equation modeling metrics. Specifically, researchers calculated Cronbach’s alpha ($lpha$), Dillon-Goldstein’s rho ($
ho_c$, also known as composite reliability), and Average Variance Extracted (AVE) using the plspm and psych packages in R.

Composite Reliability (Dillon-Goldstein’s Rho)

Because Cronbach’s alpha is sensitive to scale length (item count) and assumes tau-equivalence (equal factor loadings across all items), methodologists strongly recommend evaluating Dillon-Goldstein’s rho in structural path models. For the B2B-DMSS, all seven subscales demonstrated high composite reliability values ranging from .81 to .91, substantially exceeding the conventional psychometric threshold of .70:

• Perfectionistic and Quality Conscious Buyer (PQCB): $
  ho_c pprox .90$
• Confused and Poorly Informed Buyer (CPIB): $
  ho_c pprox .87$
• Fast and Careless Buyer (FCB): $
  ho_c pprox .85$
• Novelty and Innovation Seeking Buyer (NISB): $
  ho_c pprox .85$
• Habitual and Loyal Buyer (HLB): $
  ho_c pprox .81$
• Price Conscious Buyer (PCB): $
  ho_c pprox .91$
• Brand and Reputation Conscious Buyer (BRCB): $
  ho_c pprox .81$

Internal Consistency (Cronbach’s Alpha)

Cronbach’s alpha coefficients across the seven dimensions ranged from .57 to .88. The longer subscales demonstrated high internal consistency:

• Perfectionistic and Quality Conscious Buyer (6 items): $lpha = .88$, indicating high internal consistency and minimal measurement error.
• Confused and Poorly Informed Buyer (5 items): $lpha = .81$, demonstrating robust item cohesion.
• Fast and Careless Buyer (5 items): $lpha = .79$, confirming dependable scale homogeneity.
• Price Conscious Buyer (2 items): $lpha = .81$, an exceptionally strong alpha for a brief two-item dyad.
• Novelty and Innovation Seeking Buyer (3 items): $lpha = .74$, well within standard acceptability limits.
• Habitual and Loyal Buyer (3 items): $lpha = .67$, meeting acceptable exploratory thresholds for short organizational scales.
• Brand and Reputation Conscious Buyer (2 items): $lpha = .57$. While slightly below the conventional .60 heuristic (Hair et al., 2019), this value is attributable to the mathematical constraint of a two-item configuration. The composite reliability (Dillon-Goldstein’s $
  ho_c = .81$) and individual item factor loadings (.64 and .96) confirm that the latent construct is reliably captured.

Item-Scale Correlations and Parameter Stability

Corrected item-total correlations ($r$) were robust across all dimensions. For PQCB, item-total correlations ranged from .70 to .79. For CPIB, values spanned .53 to .76. For FCB, correlations ranged from .57 to .72. For NISB, values fell between .59 and .76. For HLB, item-total correlations were .58 to .61. For PCB, values were .78 and .80. For BRCB, values reached .60 and .64. Item distribution statistics (mean, standard deviation, skewness, and kurtosis) demonstrated normal distribution characteristics across the international sample without severe floor or ceiling distortions.

9. Factor Analysis

The structural dimensionality of the B2B-DMSS was established through a two-stage analytical sequence consisting of an exploratory Principal Component Analysis (PCA) with orthogonal rotation, followed by confirmatory structural validation using Partial Least Squares Path Modeling (Sanchez, 2013).

Initial Extraction and Component Refinement

The initial pool of 35 B2B-adapted candidate items was submitted to an exploratory PCA with varimax rotation in an initial sample of $N = 314$. Kaiser-Guttman retention criteria (eigenvalues $> 1.0$) identified eight components accounting for the majority of the cumulative variance:

• Component 1: Eigenvalue = 6.85
• Component 2: Eigenvalue = 5.33
• Component 3: Eigenvalue = 1.88
• Component 4: Eigenvalue = 1.57
• Component 5: Eigenvalue = 1.38
• Component 6: Eigenvalue = 1.29
• Component 7: Eigenvalue = 1.20
• Component 8: Eigenvalue = 1.07

Beyond Component 8, eigenvalues dropped below unity (Component 9 = 0.99; Component 10 = 0.96; continuing down to Component 35 = 0.22).

Item Elimination Decisions

Guided by Comrey and Lee’s (1992) psychometric standards, item factor loadings substantially below .55 were categorized as poor and eliminated. Six items failed to meet loading thresholds and were dropped. Additionally, one candidate item (“My company usually chooses the more expensive supplier brands”) exhibited inverse loadings relative to other component indicators; upon recalculation, its factor loading dropped to .35, warranting permanent removal.

Furthermore, Component 8 (comprising two candidate items) was eliminated entirely. This decision was justified on two psychometric grounds: first, the component yielded an unacceptable Cronbach’s alpha of $lpha = .40$, falling far short of the minimal .60 threshold (Hair et al., 2019); second, qualitative semantic evaluation revealed conceptual contradictions between its constituent items (one item measured seeking variety across diverse vendors, while the other measured purchasing at discount clearance prices). Following the removal of Component 8 and the unstable items, the final 26-item, 7-component matrix was finalized.

Confirmatory Structural Model Loadings

The finalized 26-item, 7-factor solution was tested via PLS-PM. Factor loadings ($lambda$) on respective latent constructs demonstrated clear structural separation:

• PQCB (6 items): Item 1 ($lambda = .79$), Item 2 ($lambda = .79$), Item 3 ($lambda = .83$), Item 4 ($lambda = .81$), Item 5 ($lambda = .79$), Item 6 ($lambda = .75$).
• CPIB (5 items): Item 7 ($lambda = .71$), Item 8 ($lambda = .83$), Item 9 ($lambda = .60$), Item 10 ($lambda = .83$), Item 11 ($lambda = .78$).
• FCB (5 items): Item 12 ($lambda = .72$), Item 13 ($lambda = .83$), Item 14 ($lambda = .61$), Item 15 ($lambda = .73$), Item 16 ($lambda = .72$).
• NISB (3 items): Item 17 ($lambda = .81$), Item 18 ($lambda = .89$), Item 19 ($lambda = .71$).
• HLB (3 items): Item 20 ($lambda = .76$), Item 21 ($lambda = .84$), Item 22 ($lambda = .68$).
• PCB (2 items): Item 23 ($lambda = .92$), Item 24 ($lambda = .91$).
• BRCB (2 items): Item 25 ($lambda = .64$), Item 26 ($lambda = .96$).

All indicator weights ($W$) and communalities ($h^2$) confirmed that each retained item contributes significantly to the operationalization of its respective purchasing style dimension.

  • $\text{Score}_{\text{PQCB}} = \frac{\sum(\text{Items } 1\text{ to } 6)}{6}$
  • $\text{Score}_{\text{CPIB}} = \frac{\sum(\text{Items } 7\text{ to } 11)}{5}$
  • $\text{Score}_{\text{FCB}} = \frac{\sum(\text{Items } 12\text{ to } 16)}{5}$
  • $\text{Score}_{\text{NISB}} = \frac{\sum(\text{Items } 17\text{ to } 19)}{3}$
  • $\text{Score}_{\text{HLB}} = \frac{\sum(\text{Items } 20\text{ to } 22)}{3}$

  • $\text{Score}_{\text{BRCB}} = \frac{\sum(\text{Items } 25\text{ to } 26)}{2}$
  • Critical Scoring Rule: A single composite grand score summing all 26 items must never be calculated. The seven dimensions represent independent, non-mutually exclusive behavioral orientations rather than a unidimensional purchasing trait.
  • Missing Data Handling: Forced-choice response formatting is strongly recommended during digital survey administration to prevent missing data, particularly on the brief 2-item subscales (PCB and BRCB). If omission occurs, mean imputation or expectation-maximization should be used with caution, or listwise deletion applied.
