Abstract
The Surface Warfare Officer Human Factors Attitudes Questionnaire (SWOHFAQ) is an operational psychometric instrument developed to evaluate the human factors attitudes, safety beliefs, and bridge resource management (BRM) competencies of United States Navy Surface Warfare Officers (SWOs). Adapted by psychometrician and naval researcher Paul O’Connor from the established 22-item Naval Aviator Human Factors Questionnaire (NAHFQ) and broader Crew Resource Management (CRM) assessment traditions, the instrument captures fundamental attitudes known to mediate high-risk operational performance and maritime mishap causality. The assessment measures cognitive and behavioral attitudes across four structural dimensions: My Stress (recognition and compensation for personal acute stressors and fatigue), Stress of Others (vigilance toward peer fatigue, workload, and psychological state), Communication (assertiveness, intentional briefing, operational inquiries, and psychological safety on the bridge), and Command Responsibility (perceptions of authority gradients, ship driving protocols, leadership rigidity, and delegation dynamics). The core psychometric core consists of 36 primary Likert-type items administered on a 5-point scale ranging from “Disagree Strongly” to “Agree Strongly,” complemented by operational items assessing subjective steepness of bridge authority gradients and prior completion of Bridge Resource Management training. Confirmatory factor analysis (CFA) supports a correlated four-factor structure following the systematic pruning of problematic items, mirroring robust cross-domain models derived from naval aviation. This article provides a comprehensive academic analysis of the SWOHFAQ, delineating its theoretical foundations in High-Reliability Organization (HRO) theory and Threat and Error Management (TEM), its construct and predictive validity in high-risk maritime operations, factor analytic fit parameters, scoring conventions, and the verbatim authentic item inventory.

Authors
The Surface Warfare Officer Human Factors Attitudes Questionnaire was developed and validated by Dr. Paul O’Connor, an applied psychologist and human factors researcher specializing in naval aviation, military command and control, operational healthcare safety, and maritime team coordination. Dr. O’Connor has held academic and research appointments at the Naval Postgraduate School in Monterey, California, the National University of Ireland, Galway (School of Medicine), and various international defense and safety research institutes. His research focuses extensively on the transfer of aviation-derived safety cultures, Crew Resource Management principles, and non-technical skills measurement tools into high-consequence operational domains, including naval surface warfare, commercial shipping, and acute surgical environments.
Purpose
The primary purpose of the Surface Warfare Officer Human Factors Attitudes Questionnaire is to measure and quantify the professional attitudes of naval bridge officers toward human factors principles directly implicated in operational mishaps, near-misses, and navigational collisions. In the United States Navy, Surface Warfare Officers bear ultimate tactical, technical, and operational accountability for the navigation, warfare systems, and safe seamanship of surface combatants (e.g., guided-missile destroyers, cruisers, amphibious assault platforms, and aircraft carriers). Despite the technological sophistication of modern integrated bridge systems, systemic reviews of surface fleet incidents consistently demonstrate that pure technical failure is rarely the root cause of navigational disasters; rather, degraded team communications, steep hierarchical authority gradients, unmanaged fatigue, cognitive tunnel vision, and flawed shared mental models account for the overwhelming majority of bridge mishaps.
The SWOHFAQ was engineered as both an empirical research instrument and an institutional evaluation tool to achieve three critical operational objectives:
- Evaluating Bridge Resource Management (BRM) Curriculum Effectiveness: By measuring officer attitudes before and after formal BRM training interventions, the instrument assesses whether instructional curricula successfully instill adaptive non-technical skills, lower counterproductive barriers to speaking up, and dismantle rigid, hazardous perceptions of leadership infallibility.
- Diagnosing Safety Culture and Authority Gradients: The questionnaire captures the subjective operational climate of bridge watch teams, identifying whether junior officers experience crippling reluctance to challenge erroneous decisions made by the Officer of the Deck (OOD) or the Commanding Officer (CO).
- Benchmarking Human Performance Vulnerabilities: By examining officer self-perceptions concerning stress, chronic sleep debt, and operational workload, the scale exposes dangerous cultural myths, such as the pervasive belief that true military professionals are immune to fatigue-induced cognitive degradation or that personal performance remains unaltered during severe operational emergencies.
In applied research, the tool permits cross-platform comparisons between vessel classes (such as destroyers versus amphibious ships), longitudinal tracking across career progression from junior division officer to prospective commanding officer, and psychometric validation of non-technical skills within simulated bridge maneuvering environments.
Psychological Construct
The SWOHFAQ assesses non-technical skills and safety attitudes through a multidimensional construct rooted in the social and cognitive psychology of high-risk work domains. The instrument conceptualizes human factors attitudes across four foundational subscales, complemented by operational watchstanding climate indices:
1. My Stress
The My Stress construct examines an officer’s metacognitive awareness of, and willingness to acknowledge, personal biological and psychological vulnerability to stressors. Military and naval subcultures historically celebrate stoicism, physical endurance, and invulnerability. Within the context of the SWOHFAQ, this subscale captures an individual’s realistic recognition that severe physiological fatigue, personal emotional disruptions, and cognitive task saturation degrade decision-making capacity, vigilance, and reaction time. Counterproductive attitudes within this dimension are exemplified by statements asserting that personal performance is fully insulated from exhaustion or that true professionals never commit errors. Adaptive attitudes reflect an accurate appraisal of human limitations and a proactive willingness to communicate excessive personal workload across the chain of command.
2. Stress of Others
The Stress of Others dimension measures interpersonal situational awareness and mutual team monitoring. It gauges the extent to which an officer actively scans, detects, and compensates for indicators of exhaustion, cognitive saturation, or acute anxiety in fellow bridge team members. In high-tempo naval operations, single-operator overload can cause catastrophic breakdowns in the peripheral monitoring of surface contacts. Adaptive attitudes in this domain acknowledge that crew members share collective responsibility for monitoring peer readiness, managing mutual workload distribution, adjusting to divergent personal working styles, and identifying operational degradation in junior or peer watchstanders prior to watch turnover.
3. Communication
The Communication subscale captures attitudes toward the structural and interpersonal mechanisms required to build and preserve a shared mental model on the bridge. This construct encompasses three core behaviors: (a) structured briefing and debriefing protocols (e.g., recognizing that comprehensive pre-briefs establish team role clarity and that watch debriefings are necessary for iterative learning); (b) operational assertiveness and psychological safety (e.g., affirming that any team member, regardless of seniority, has an obligation to voice safety concerns immediately); and (c) explicit verbalization of navigational intentions (e.g., requiring the ship’s conn or OOD to announce maneuvers clearly so that all team members can verify course changes).
4. Command Responsibility
The Command Responsibility construct explores beliefs regarding the distribution of authority, tactical delegation, and leadership behavior in high-risk operational environments. It addresses the dangerous “heroic captain” mythology, in which the Commanding Officer or Officer of the Deck is expected to physically drive the ship and resolve all anomalies single-handedly. Furthermore, this dimension assesses attitudes toward the authority gradient, explicitly testing whether officers believe junior watchstanders should refrain from questioning the decisions of senior officers during normal or emergency operations. Constructive leadership attitudes view effective commanders as facilitators who invite input, share situational awareness, and delegate tactical execution while retaining overall command accountability.
Theoretical Framework
The theoretical architecture of the SWOHFAQ draws upon several converging paradigms in organizational psychology, systems safety, and cognitive ergonomics:
Crew Resource Management and the Helmreich Model
The seminal foundation of the SWOHFAQ originates from the Crew Resource Management (CRM) and Bridge Resource Management paradigms initially codified in commercial aviation and adapted for maritime operations. Robert Helmreich and colleagues established that technical proficiency is an insufficient safeguard against system accidents; non-technical skills—encompassing leadership, teamwork, situational awareness, and communication—form the essential human barrier against catastrophe. The SWOHFAQ directly adapts the core psychometric lineage of Helmreich’s Cockpit Management Attitudes Questionnaire (CMAQ) and Flight Management Attitudes Questionnaire (FMAQ), translating aviation constructs into the distinct hierarchical, linguistic, and tactical culture of naval warship bridge teams.
Threat and Error Management (TEM)
Under the Threat and Error Management model, human error is recognized as a normal, unavoidable consequence of human cognitive design operating within complex, dynamic environments. Threats (e.g., adverse weather, dense fishing traffic, equipment malfunction, naval combat conditions) require proactive counter-measures, while internal errors (e.g., navigational miscalculations, miscommunicated helm commands) must be trapped before they produce undesirable operational states. The SWOHFAQ measures attitudes that serve as the psychological antecedents of robust TEM behaviors. An officer who harbors the belief that “a true professional does not make mistakes” operates under a flawed theoretical mental model that suppresses error disclosure, prevents early mitigation, and inhibits collaborative threat management.
High-Reliability Organization (HRO) Theory and Reason’s Swiss Cheese Model
High-Reliability Organization theory, articulated by Karl Weick and Kathleen Sutcliffe, posits that organizations operating in zero-tolerance-for-error environments survive through a collective “preoccupation with failure,” “reluctance to simplify interpretations,” “sensitivity to operations,” and “deference to expertise.” On a naval bridge, deference to expertise requires that when a junior radar observer detects an imminent risk of collision, the operational hierarchy must flatten instantaneously to allow that vital data to override a senior officer’s faulty mental model. This operational dynamic addresses James Reason‘s Swiss Cheese model of accident causation, ensuring that cognitive and institutional latent failures do not align to permit an active navigational failure to culminate in a fatal collision.
Validity
Validation of the SWOHFAQ has involved progressive stages of structural, construct, and concurrent empirical validation conducted across military maritime cohorts.
Construct and Factorial Validity
During the primary psychometric adaptation from the Naval Aviator Human Factors Questionnaire to the surface warfare environment, O’Connor (2011) examined the factorial stability of the instrument among active-duty U.S. Navy Surface Warfare Officers participating in Bridge Resource Management curricula. Confirmatory factor analysis (CFA) tested the proposed four-factor theoretical model (My Stress, Stress of Others, Communication, and Command Responsibility). As observed during the aviation parent-instrument refinement, the initial complete item battery contained items that displayed unacceptable cross-loadings or inadequate item-total correlations within the surface community. Items 7, 15, 18, and 19 were empirically discarded based on modification indices and standardized residual analysis, yielding an optimized, parsimonious four-factor solution that demonstrated acceptable goodness-of-fit metrics comparable to established naval aviation benchmarks.
Convergent and Discriminant Validity
The SWOHFAQ has demonstrated convergent validity through its significant correlations with external measures of organizational safety climate, bridge crew psychological safety scales, and behavioral assessments of watchstander assertiveness. Officers scoring high on the Communication dimension exhibit significantly higher self-reported willingness to challenge senior watch officers in simulated navigation scenarios. Discriminant validity is evidenced by the scale’s ability to dissociate non-technical attitudes from raw technical knowledge of navigation rules of the road (COLREGS). While technical proficiency does not predict scores on the Command Responsibility or Stress of Others subscales, SWOHFAQ dimensions correlate significantly with simulator-measured team performance during complex maritime crisis injections.
Predictive and Evaluative Sensitivity
The instrument exhibits robust sensitivity to educational interventions. In empirical evaluations of BRM course effectiveness (O’Connor, 2011), post-training administrations revealed statistically significant positive attitude shifts across the Communication and Command Responsibility dimensions. Specifically, participating officers demonstrated a marked reduction in authoritarian bridge beliefs (e.g., agreeing that junior officers should question seniors when safety is compromised) and showed a heightened valuation of formal pre-briefs and team workload alerts.
Reliability
The internal consistency and temporal stability of the SWOHFAQ reflect standard psychometric benchmarks observed across attitude-measurement inventories adapted from Helmreich’s original human factors scales:
- Internal Consistency: Cronbach’s alpha coefficients for the established subscales demonstrate acceptable operational reliability. In naval evaluation cohorts, the subscales generally range between α = .64 and α = .78. While these coefficients are moderate compared to clinical personality inventories, they are typical for multidimensional human factors attitude instruments measuring distinct, context-dependent operational beliefs (where diverse facets of stress, assertiveness, and leadership do not represent redundant semantic rephrasings).
- Composite Subscale Alphas: In empirical studies, the Communication subscale consistently exhibits the highest internal consistency (α ≈ .74 to .78), reflecting cohesive professional consensus regarding briefing protocols and clear communication. The Command Responsibility subscale demonstrates alpha values ranging from α = .66 to .73, reflecting evolving cultural tensions between traditional autocratic maritime command models and modern collaborative bridge doctrines.
- Test-Retest Stability: Evaluation of control cohorts who received no interim BRM intervention over 4-to-8-week intervals demonstrated stable test-retest correlation coefficients (r > .70), indicating that the SWOHFAQ captures enduring cognitive and behavioral attitudes rather than transient situational moods.
Factor Analysis
The factorial structure of the SWOHFAQ was confirmed through structural equation modeling and confirmatory factor analysis (CFA) executed on military watchstander data. Initial exploratory factor analyses (EFA) revealed that several items adapted from naval flight decks did not map cleanly onto bridge operations due to differing physical layouts, watch team sizes, and continuous shift patterns.
Structural Pruning and Model Fit
In the psychometric evaluation reported by O’Connor (2011), four items (Items 7, 15, 18, and 19) were removed to resolve structural attenuation and collinearity distortions:
- Item 7: “Truly professional Surface Warfare Officers can leave personal problems behind during underway operations” (demonstrated problematic bifurcated loadings across My Stress and individual professional identity constructs).
- Item 15: “Personal problems can adversely affect my performance” (redundancy issues with adjacent items).
- Item 18: “The Officer of the Deck should take physical control and drive the ship in emergency and non-standard situations” (ambiguity regarding operational definitions of physical ship-handling versus supervisory conning).
- Item 19: “Effective crew coordination requires the watch team to consider the personal work styles of other team members” (poor discrimination on the latent team coordination factor).
Following the removal of these four items, the resulting four-factor model demonstrated an acceptable fit to the empirical data:
- Chi-Square / Degrees of Freedom Ratio (χ²/df): ≤ 2.10, indicating acceptable overall structural harmony.
- Comparative Fit Index (CFI): > .90, satisfying established benchmarks for specialized organizational safety attitude measures.
- Root Mean Square Error of Approximation (RMSEA): .052 (90% CI [.044, .060]), indicating close approximate fit to the population covariance matrix.
- Standardized Root Mean Square Residual (SRMR): .058, confirming low average discrepancies between observed and hypothesized correlations.
Instrument / Measurement Tool
The operational questionnaire is formatted as a structured, self-report psychometric test comprising primary attitude items, situational authority gradient indices, and demographic watchstanding covariates:
- Test Type: Multidimensional human factors and safety attitudes questionnaire.
- Administration Format: Paper-and-pencil or secure computerized psychometric assessment administered individually in academic, training, or operational underway environments.
- Core Item Inventory: 36 numbered Likert-type items measuring the spectrum of stress, workload, communication, psychological safety, and command dynamics.
- Response Scale (Items 1–36): A 5-point Likert scale formatted with authentic categorical anchors:
- A: Disagree Strongly
- B: Disagree Slightly
- C: Neutral
- D: Agree Slightly
- E: Agree Strongly
- Hierarchical Insecurity Index (Item 37): A targeted five-point categorical frequency metric evaluating the steepness of the bridge authority gradient: “How frequently in your most recent watch team are junior personnel afraid to express disagreement with more senior personnel?” (Very frequently, Frequently, Sometimes, Seldom, Very seldom).
- Training Exposure Index: Dichotomous verification item (“Have you attended Bridge Resource Management training? [Yes / No]”).
- Demographic and Operational Covariates: Explicit profiling items recording Commissioning Source (STA-21, ECP, LDO, Naval Academy), Rank (O1–O2, O3, O4, O5, O6), Gender (Male, Female), Vessel Class (Destroyer, Frigate, Amphibious, Carrier), Primary Operational Department (Operations, Engineering, Combat, Executive), and Cumulative Years of Service as a Surface Warfare Officer.
- Scoring Rules: Items expressing non-adaptive human factors beliefs (e.g., “A true professional does not make mistakes”; “Commanding Officers who encourage suggestions from ship’s crew are weak leaders”; “Junior officers should not question the Officer of the Deck’s decisions in emergencies”) are reverse-scored prior to dimensional aggregation. Higher composite scores represent superior alignment with established Bridge Resource Management principles, higher non-technical psychological safety, and heightened self-awareness of human performance limitations.
