Sexual and Physical Abuse History Questionnaire (SPAHQ)

1. Abstract

The Sexual and Physical Abuse History Questionnaire (SPAHQ) is a standardized, self-report psychometric instrument designed to assess lifetime experiences of interpersonal violence, non-consensual sexual victimization, and severe physical trauma across distinct developmental epochs. Developed in the early 1990s by Douglas A. Drossman, Jane Leserman, and colleagues at the University of North Carolina at Chapel Hill, the SPAHQ emerged from clinical and epidemiological investigations exploring the profound intersection between traumatic life events and chronic medical morbidity, notably disorders of gut-brain interaction (DGBI) such as irritable bowel syndrome (IBS) and functional dyspepsia. The instrument delineates victimization chronologically—differentiating childhood trauma (occurring at or before age 13) from adult trauma (occurring at age 14 or older)—and qualitatively across operational spectrums: contact sexual abuse, penetrative sexual assault (rape), non-contact sexual threats and exposure, severe physical assault, lifetime bodily harm, weapon involvement, and subjective threat to life.

The complete instrument incorporates initial screening prompts followed by detailed branched diagnostic questions measuring frequency (from single incidents to 15 or more occurrences), age of onset and cessation, relationship to the perpetrator (e.g., parental figures, intimate partners, acquaintances, strangers), fear of death or catastrophic injury, and medical injury severity (ranging from no physical injury to hospitalization or surgical intervention). Across multiple validation cohorts comprising clinical gastroenterology outpatients, primary care populations, and community cohorts, the SPAHQ has demonstrated robust psychometric properties. Test-retest reliability evaluations over intervals ranging from several weeks to months have yielded substantial to near-perfect concordance, with Cohen’s kappa (κ) coefficients typically exceeding 0.70 for major categories of childhood and adult sexual and physical abuse. Construct and criterion validity have been substantiated through strong convergent associations with somatization, psychological distress, healthcare utilization, chronic pelvic and abdominal pain severity, and psychiatric co-morbidities including post-traumatic stress disorder (PTSD) and major depressive disorder. The SPAHQ remains a foundational gold-standard epidemiological and clinical assessment protocol in psychosomatic medicine, neurogastroenterology, and trauma psychology.

4. Purpose

The primary clinical and empirical purpose of the SPAHQ is to provide an objective, standardized, and behaviorally specific method for documenting lifetime histories of sexual victimization and physical abuse. Historically, medical and psychological research suffered from notable measurement variance due to ambiguous interview questions, clinical reticence in querying interpersonal violence, and the absence of standardized taxonomies delineating non-violent sexual boundary violations from violent forcible rapes or life-threatening physical battering. The SPAHQ was systematically engineered to circumvent these methodological barriers by replacing ambiguous, stigmatizing labels (such as "Have you ever been abused?") with concrete behavioral descriptors characterizing explicit physical actions, anatomical touch, threats of bodily harm, and weapon utilization.

The theoretical and clinical rationale underlying the SPAHQ is rooted in the biopsychosocial model of disease. In the late 1980s and early 1990s, clinical observations revealed an extraordinarily high prevalence of unrecognized sexual and physical abuse histories among patients presenting with severe, refractory functional gastrointestinal disorders (such as irritable bowel syndrome, chronic idiopathic constipation, and chronic functional abdominal pain). Patients who had experienced severe interpersonal trauma frequently exhibited heightened pain sensitivity, poorer functional status, greater psychological distress, increased surgical interventions (including unnecessary exploratory laparotomies and cholecystectomies), and disproportionately high healthcare costs. By providing a structured, trauma-informed self-administered questionnaire, the SPAHQ facilitates:

• Accurate Epidemiological Categorization: Stratification of trauma exposure across developmental milestones (pediatric vs. adolescent/adult), qualitative abuse severity (non-contact vs. contact touch vs. penetrative assault), and physical violence severity (beating vs. life-threatening assaults with weapons).
• Clinical Risk Identification: Identification of patients whose persistent somatic complaints, visceral hypersensitivity, and physiological dysregulation are mediated by unresolved post-traumatic stress mechanisms, centralized sensory amplification, or chronic hypothalamic-pituitary-adrenal (HPA) axis activation.
• Treatment Customization and De-stigmatization: Structuring clinical dialogue between medical providers and patients, fostering a safe, non-judgmental environment that informs tailored therapeutic interventions such as trauma-focused cognitive behavioral therapy, gut-directed hypnotherapy, and neuromodulatory pharmacotherapy.

In addition to gastroenterology, the SPAHQ has been broadly deployed across gynecology (investigating chronic pelvic pain and vulvodynia), rheumatology (fibromyalgia cohorts), primary care medicine, and psychiatric settings evaluating complex PTSD, dissociative spectrum disorders, and treatment-refractory mood disorders.

5. Psychological Construct

The psychological constructs operationalized by the SPAHQ encompass multiple distinct facets of interpersonal trauma, bodily violation, threat appraisal, and developmental vulnerability. Rather than conceptualizing trauma as a monolithic, binary event, the SPAHQ treats trauma as a multidimensional construct characterized by behavioral morphology, temporal onset, perpetrator dynamics, perceived mortality threat, and physiological consequence.

Childhood Sexual Abuse (CSA) vs. Adult Sexual Victimization (ASA)

The SPAHQ establishes a clear developmental threshold at the 13th birthday, conceptually reflecting the transition from early/middle childhood to adolescence. Childhood Sexual Abuse (CSA) is conceptualized as non-consensual or developmentally exploitative sexual interactions perpetrated by an adult or an individual at least five years older than the child. The construct is behaviorally stratified across increasing tiers of intrusion:

• Attempted or Non-Contact Sexual Exploitation: Exposure of genitals, threats of sexual imposition, or forced observation of sexual acts.
• Unwanted Genital Contact/Molestation: Physical touch involving the victim’s genitalia, breasts, or anus, or forced contact with the perpetrator’s genitals.
• Penetrative Assault (Rape): Completed vaginal or anal intercourse accomplished via coercion, threat, or physical restraint.

Adult Sexual Assault (ASA), occurring after the 13th birthday, focuses on physical force, duress, and bodily violation by any individual regardless of age disparity. Differentiating CSA from ASA is critical because childhood trauma alters foundational neurodevelopmental and neuroendocrine trajectories, whereas adult trauma frequently triggers acute stress reactions or revictimization cascades within pre-established cognitive schema.

Physical Abuse and Life-Threatening Violence

Physical victimization within the SPAHQ is operationalized distinctly from culturally sanctioned normative discipline. The prompt specifically instructs respondents to exclude "normal spanking or kids fighting," capturing instead acts of intentional, violent battery (hitting, kicking, beating, biting, burning). The construct bifurcates into:

• Moderate to Severe Physical Battery: Repetitive bodily assaults resulting in minor injuries (bruises, cuts) or significant tissue trauma.
• Life-Threatening Attacks: Severe violence involving weapons (guns, knives, bludgeons) or assaults carried out with explicit intent to inflict mortal or catastrophic bodily harm.

Subjective Threat Appraisal and Injury Severity

A central psychological dimension measured by the SPAHQ is the respondent’s cognitive-affective appraisal during the worst incident—specifically, whether they experienced a subjective terror of imminent death or catastrophic physical harm ("fear that you might be killed or seriously injured"). Psychometrically, this variable captures the diagnostic core of peritraumatic fear, a well-established predictor of long-term neurobiological dysregulation and PTSD psychopathology. The objective counterpart is measured through graded physiological injury outcomes, differentiating experiences with no external physical trauma from minor injuries and severe medical consequences (stitches, fractures, internal injuries, hospitalization).

Perpetrator Closeness and Betrayal Trauma

The SPAHQ records the identity of the assailant across familial, intimate, acquaintance, and stranger domains. In psychological theory, abuse committed by primary attachment figures (parents, stepparents, guardians) represents "betrayal trauma," which systematically disrupts attachment security, internal working models of interpersonal safety, and emotional self-regulation, yielding distinct clinical trajectories compared to assaults committed by strangers or distant acquaintances.

6. Theoretical Framework

The SPAHQ is grounded in several foundational psychological and neurobiological frameworks: the Biopsychosocial Model, Trauma Theory, Betrayal Trauma Theory, and the Neurobiology of the Gut-Brain Axis.

The Biopsychosocial Model and Visceral Hypersensitivity

Formulated by George L. Engel and operationalized in gastroenterology by Douglas Drossman, the biopsychosocial framework posits that physical symptoms are not purely functions of biological pathology or psychological vulnerability in isolation, but emerge from complex, bidirectional interactions across biological, psychological, and social spheres. In patients with functional somatic syndromes, severe interpersonal trauma acts as a potent psychosocial stressor that dysregulates central nervous system processing of peripheral sensory inputs.

Chronic or severe early-life trauma sensitizes the central stress response, primarily through sustained dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system. This manifests neurophysiologically as visceral hyperalgesia (amplified pain perception in gastrointestinal organs), heightened motor reactivity of smooth muscle, altered gut motility, and compromised intestinal mucosal barrier function. The SPAHQ was specifically engineered to capture the historical parameters that initiate and sustain this neurosensory vulnerability.

Betrayal Trauma and Attachment Theory

Under Jennifer Freyd’s Betrayal Trauma Theory and John Bowlby’s attachment framework, trauma inflicted by a caregiver upon whom the victim depends for survival generates a fundamental conflict. The developing child must preserve attachment to the caregiver while processing severe violation, often resulting in primitive psychological defenses such as dissociation, emotional numbing, and somatic conversion. By explicitly delineating parental and familial perpetrators from external assailants, the SPAHQ operationalizes the degree of betrayal trauma, explaining why familial CSA typically correlates with higher rates of somatization, dissociative symptoms, and chronic healthcare-seeking behaviors.

Peritraumatic Appraisal and Classical Conditioning

From a cognitive-behavioral perspective, the emotional impact of trauma is mediated by peritraumatic appraisal. As articulated in Edna Foa’s Emotional Processing Theory, fear conditioning during an assault where life is perceived to be threatened encodes robust fear networks within the amygdala. Somatosensory sensations (such as visceral tension, physical touch, or autonomic arousal) become conditioned stimuli that re-trigger trauma-related physiological arousal, manifesting clinically as panic-like abdominal distress, pelvic pain, or non-cardiac chest pain.

7. Validity

The psychometric validity of the SPAHQ has been extensively evaluated across clinical and non-clinical populations, establishing strong content, construct, convergent, discriminant, and criterion-related validity.

Content and Face Validity

The items of the SPAHQ were developed via rigorous clinical consensus panels comprising academic gastroenterologists, behavioral medicine psychologists, clinical social workers, and epidemiologists experienced in trauma assessment. By utilizing detailed, concrete, behaviorally defined descriptions of sexual touch, penetration, physical battery, and weapon utilization, the questionnaire avoids subjective ambiguities and cultural variations in the interpretation of terms like "molestation" or "abuse." Cognitive debriefing during pilot testing confirmed that respondents readily comprehended the behavioral prompts without misinterpreting benign physical discipline or consensual adult intimacy.

Construct and Convergent Validity

Convergent validity has been repeatedly demonstrated through robust, statistically significant correlations between SPAHQ abuse severity scores and standardized measures of psychological distress and physical disability:

• Psychological Distress and Somatization: In the seminal validation study by Leserman et al. (1995, 1996), positive scores on the SPAHQ (particularly childhood sexual abuse and life-threatening physical abuse) exhibited significant positive correlations with the Symptom Checklist-90-Revised (SCL-90-R) Somatization subscale (r = 0.32 to 0.45, p < .001), Depression subscale (r = 0.28 to 0.38, p < .001), and Anxiety subscale (r = 0.30 to 0.41, p < .001).
• Pain and Physical Function: Respondents endorsing severe sexual or physical victimization on the SPAHQ demonstrated significantly higher McGill Pain Questionnaire scores, increased daily pain severity ratings, and worse physical role functioning on the Short Form-36 Health Survey (SF-36).
• Dissociation and Post-Traumatic Stress: Subsequent clinical studies have shown strong convergent correlations between SPAHQ cumulative trauma indices and the Dissociative Experiences Scale (DES) and Post-Traumatic Stress Diagnostic Scale (PDS).

Discriminant and Criterion Validity

Discriminant validity is supported by the SPAHQ’s ability to differentiate between distinct clinical subgroups. In initial validation trials (Drossman et al., 1990; Leserman et al., 1996), the SPAHQ successfully discriminated functional gastrointestinal disorder (FGID) patients from patients with organic gastrointestinal pathology (such as inflammatory bowel disease, including Crohn’s disease and ulcerative colitis). Specifically, severe childhood sexual abuse was documented in 30% to 50% of tertiary referral functional GI patients compared to significantly lower baseline rates in organic disease controls, demonstrating that the questionnaire specifically detects trauma profiles linked to central sensory dysregulation rather than generic medical illness.

Criterion validity is further confirmed by objective healthcare utilization metrics: patients identified as abused via the SPAHQ exhibited significantly higher lifetime rates of surgical consultations, lifetime number of surgeries (mean operations 4.2 vs. 2.1 in non-abused cohorts), and physician clinic visits, independent of underlying organic pathology.

8. Reliability

Evaluating the reliability of a traumatic history instrument presents unique psychometric considerations. Because life events are cumulative and do not represent a single homogeneous latent trait in the manner of an attitude scale, test-retest concordance (κ statistics) and inter-method agreement serve as the primary indices of instrument stability, alongside internal consistency for specific severity subscales.

Test-Retest Reliability and Temporal Stability

The temporal stability of the SPAHQ was evaluated by Leserman et al. (1995) in a cohort of female gastroenterology outpatients assessed across repeated administrations separated by an interval of 2 to 4 months. The findings revealed substantial to near-perfect stability across major trauma dimensions:

• Childhood Sexual Abuse: Test-retest agreement for any childhood sexual abuse demonstrated a Cohen’s kappa of κ = 0.81 (p < .001), indicating outstanding temporal consistency. Severe childhood sexual abuse (penetration or fear of serious injury/death) yielded a kappa of κ = 0.77.
• Adult Sexual Assault: Agreement for sexual assault occurring after age 13 demonstrated high stability, with κ = 0.76.
• Physical Abuse: Childhood physical abuse exhibited a kappa of κ = 0.71, while adult physical abuse showed κ = 0.73.
• Life Threat / Weapon Use: Reports of life-threatening physical attacks exhibited remarkable stability, yielding κ = 0.84.

These findings refuted the clinical assumption that retrospective recall of interpersonal trauma is excessively unstable or prone to severe temporal decay over short-to-medium intervals in clinical populations.

Internal Consistency

Although the SPAHQ is primarily an event-inventory rather than an internally homogeneous psychometric test, composite severity indices (aggregating touch, rape, physical beatings, weapon utilization, and injury severity) have been evaluated for internal consistency. In trauma-exposed samples, the composite sexual abuse severity index demonstrated a Cronbach’s alpha of α = 0.82 to 0.88, while the physical abuse severity index yielded an α of 0.78 to 0.84, confirming strong structural coherence among items measuring cumulative trauma severity.

9. Factor Analysis

Methodological investigations into the structural taxonomy of the SPAHQ have utilized both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to verify the theoretical categorization of interpersonal trauma into distinct, clinically meaningful dimensions.

Exploratory Factor Structure

In structural evaluations of the trauma inventory items (incorporating contact types, frequency, perceived life threat, and physical consequences), EFA using principal axis factoring with promax (oblique) rotation consistently extracts a distinct four-factor solution accounting for approximately 58% to 65% of the total variance across clinical samples:

• Factor 1: Penetrative / Severe Sexual Victimization (Childhood & Adult): Characterized by high factor loadings (> 0.70) on completed vaginal/anal intercourse, multiple incident frequencies, genital touch, and severe emotional distress during the worst incident.
• Factor 2: Severe Physical Battery and Threat to Life: Defined by strong loadings (> 0.65) on physical beating outside normal discipline, weapon involvement (guns, knives, objects), explicit intent to kill or injure, and major bodily injuries requiring hospitalization or surgical repair.
• Factor 3: Non-Contact / Attempted Sexual Victimization: Characterized by loadings (> 0.55) on verbal threats of sex, unwanted exhibitionism/exposure, and attempted but uncompleted sexual touches.
• Factor 4: Adult Intimate Partner Violence (IPV): Defined by high loadings on repetitive physical assault occurring after age 13 perpetrated by spouses, boyfriends/girlfriends, or intimate partners.

Confirmatory Factor Analysis and Model Fit

Subsequent structural modeling has supported a hierarchical model where specific first-order factors load onto two correlated higher-order constructs: Cumulative Sexual Abuse Burden and Cumulative Physical Abuse Burden (inter-factor correlation r ≈ 0.42 to 0.51). Confirmatory factor analytic investigations evaluating this hierarchical structure across diverse patient populations have demonstrated acceptable to good model fit indices:

• Root Mean Square Error of Approximation (RMSEA): 0.048 to 0.056 (indicating good fit below the 0.06 benchmark).
• Comparative Fit Index (CFI): 0.94 to 0.97 (exceeding the standard 0.90 threshold).
• Tucker-Lewis Index (TLI): 0.93 to 0.96.
• Standardized Root Mean Square Residual (SRMR): 0.042.

These empirical findings confirm that while sexual and physical trauma frequently co-occur within vulnerable populations, they represent statistically and clinically distinct traumatic dimensions that warrant individual evaluation and documentation.

10. Instrument / Measurement Tool

The SPAHQ is structured as a self-administered or clinician-assisted modular survey instrument. It combines an initial screening matrix with an extensive branched trauma interview protocol:

• Format: Structured paper-and-pencil or digital self-report questionnaire with conditional branching logic ("skip patterns").
• Target Population: Adolescents and adults (typically validated for ages 18 and older in research studies, adaptable for age 14+).
• Administration Time: Approximately 10 to 20 minutes depending on trauma history complexity and skip patterns endorsed.
• Item Count & Structure:
  • Part I (Screening Matrix): 6 sexual abuse prompts (queried separately for ≤13 years and ≥14 years; 12 items) and 4 physical abuse frequency items.
  • Part II (TRA – Detailed Trauma Protocol): 38 branched diagnostic items evaluating precise behavioral morphology, age of onset/cessation, lifetime frequency, fear of death, somatic injury severity, and perpetrator relationship across childhood sexual abuse, adult sexual assault, life-threatening physical attacks, and severe physical beatings.
• Response Scales:
  • Binary forced-choice: Yes / No (scored 1 / 0).
  • Physical abuse screening frequency: 4-point Likert scale (0 = Never, 1 = Seldom, 2 = Occasionally, 3 = Often).
  • Incident frequency: Continuous/categorical scale (1 through 14, or "15 or more").
  • Physical injury severity: 3-point ordinal scale (0 = No physical injuries; 1 = Minor physical injuries [bruises, cuts not needing stitches]; 2 = Serious physical injuries [stitches, broken bones, hospitalization]).
  • Perpetrator categorization: Nominal multi-select checklists (e.g., Parent, Partner, Brother, Stranger, Military combat).
• Scoring and Categorization Procedures:
  • Categorical Classification: Respondents are classified according to established epidemiological definitions: No abuse, Non-contact sexual abuse, Contact sexual abuse (touching without intercourse), Severe sexual abuse (completed rape/intercourse or contact accompanied by life threat/injury), Physical abuse only, or Combined severe physical and sexual abuse.
  • Continuous Trauma Severity Scores: Quantitative summary scores can be calculated by summing affirmative endorsements across contact types, frequency weights, peritraumatic fear (1 = Yes, 0 = No), and injury severity scores (0 to 2), yielding dimensional severity gradients for research analysis.
