Physical and Sexual Abuse of Adults - A Comprehensive Answer
DEFINITIONS AND OVERVIEW
Physical abuse refers to the use of physical force against a person that results in bodily injury, physical pain, or impairment. This encompasses hitting, slapping, pushing, kicking, burning, choking, striking with objects, and the improper use of physical restraints or medications. In the context of intimate partner violence (IPV), physical abuse ranges from "high-severity" forms (threats with or use of a weapon, burning, choking, resulting in broken bones, head or internal injuries) to "low-severity" forms (slapping, kicking without injury, bruising, minor cuts, sprains).
Sexual abuse/assault is a crime of violence, conquest, control, and aggression - not passion. It encompasses a continuum of sexual activity ranging from coercion to contact abuse (unwanted kissing, touching, fondling) to forcible rape. The revised FBI definition recognises that survivors and perpetrators may be of any gender and that oral and anal penetration with an object or body part constitutes rape. Physical force is no longer a legal requirement, thereby encompassing individuals who are intoxicated, unconscious, mentally or physically incapable of demonstrating consent, or otherwise vulnerable.
Rape is legally defined by three elements:
- Use of physical force, deception, intimidation, or the threat of bodily harm
- Lack of consent or inability to give consent (due to age, alcohol/drug impairment, unconsciousness, or mental/physical impairment)
- Oral, vaginal, or rectal penetration with a penis, finger, or object
Subtypes include: acquaintance rape, date rape, statutory rape, marital rape, and incest.

EPIDEMIOLOGY AND PREVALENCE
-
Nearly 30% of women and 10% of men in the United States have experienced some form of physical or sexual abuse from an intimate partner (National Intimate Partner and Sexual Violence Survey, NISVS 2011).
-
The NISVS found 27.3% of women and 11.5% of men experienced sexual violence, physical violence, or stalking by an intimate partner during their lifetimes.
-
The NCVS reported over 521,870 domestic violence incidents in 2019, including 310,320 cases of IPV.
-
Approximately 18% of women have been raped during their lifetimes; 8.8% by an intimate partner.
-
Among female rape survivors: 51% reported a current/former intimate partner, 41% an acquaintance, and 13% a family member - only 14% reported a stranger.
-
78.7% of female rape victims were first raped before age 25; 40.4% before age 18.
-
Only 26% of rape survivors seek medical attention after an assault.
-
Sexual assault is the fastest growing, most frequently committed, and most underreported crime.
-
Rape-related pregnancy rate: approximately 5% among girls and women aged 12-45.

RISK FACTORS
For Physical Abuse / IPV Perpetration
Individual factors: younger age of victim, pregnancy, low income, substance use, prior exposure to violence in childhood, low educational level, borderline or antisocial personality traits.
Relationship factors: marital discord and instability, economic stressors, male with multiple partners, male dominance in the family.
Community/Societal factors: poverty, overcrowding, social acceptance of IPV, lack of sanctions against it, traditional or rigid gender roles.
For Sexual Violence Perpetration (CDC factors)
Individual: prior sexual victimization or perpetration, substance use, impaired empathy, aggressiveness, acceptance of violence, early sexual initiation, coercive sexual fantasies, hostility toward women.
Relationship/Environmental: family environments characterised by physical violence, emotionally unsupportive families, associating with sexually aggressive peers, poor parent-child relations.
- Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7941-7942
PERPETRATOR PROFILE
Perpetrators of domestic violence span all races, cultures, ethnicities, genders, religions, educational levels, and socioeconomic strata. Two broad typologies are recognised:
- Emotionally dependent type: High jealousy, interpersonal dependency, anger, low self-esteem. Interprets partner's behaviour as betrayal; anger explodes into violence. More emotionally reactive.
- Antisocial/narcissistic type: Low empathy, hostile attitudes toward women. Becomes less physiologically aroused as violence escalates. Highest rates of alcohol dependence.
Observable traits include verbal abuse, projecting blame onto victims, objectifying victims, isolating them from social support, and presenting as charming/manipulative in public while being hostile in private.
- Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7942-7943
CLINICAL PRESENTATION / SIGNS AND SYMPTOMS
Physical Signs of Ongoing Abuse
- Frequent or serious bruises (particularly in non-accidental locations - torso, face, neck)
- Fractures, sprains, or serious cuts
- Burns or bite marks
- Strangulation signs (petechiae, neck bruising, hoarseness, dysphagia)
- Pelvic or genital pain
- Vaginal discharge or bleeding
- Abdominal pain, breast pain, chest pain
- Fainting, shortness of breath
Behavioural/Psychological Signs
- Loss of appetite, eating disturbances (binges, self-induced vomiting)
- Nightmares, problems sleeping
- Diarrhoea or constipation (somatic symptoms)
- Difficulty passing urine
- Frequent or severe headaches
- Partner who is controlling, speaks for the victim, refuses to leave the room
Pattern Recognition
-
Injuries inconsistent with the history provided
-
Delay in seeking treatment
-
Partner reluctant to allow private interview with patient
-
Injuries at different stages of healing
-
Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7944-7945
SEQUELAE OF ABUSE
Physical Sequelae
- Chronic pelvic pain, sexual dysfunction
- Chronic pain syndromes, functional gastrointestinal disorders
- Headaches, multiple somatic symptoms
- STDs, HIV/AIDS, unintended pregnancy
- Reproductive health complications
Psychological Sequelae
Post-Sexual Assault: The most common sequelae are PTSD, affective (depressive) disorders, substance misuse, disordered eating, and sexual disorders. Perceived life threat and physical injury further increase PTSD risk.
Rape Trauma Syndrome is a constellation of physical and psychological symptoms that unfolds in two phases:
- Acute/Disorganisation Phase (days to weeks): Fear, helplessness, disbelief, shock, guilt, humiliation, embarrassment, anger, self-blame. Intrusive memories, emotional blunting, hypersensitivity to stimuli, insomnia, nightmares, somatic symptoms, fear of retaliation.
- Integration/Resolution Phase (weeks to months): Apparent return to routine but repression of anger, fear, guilt. Gradual acceptance. Over the long term: difficulty with work and family relationships, disruption of existing relationships, job loss (nearly half lose or quit jobs in the year following rape).
Domestic Violence Sequelae: Depression, anxiety, low self-esteem, substance abuse (both risk factor and consequence), sexual dysfunction, multiple somatic symptoms. Research shows a dose-effect: escalating violence correlates with increasing physical complaints. Suicide attempts are significantly more frequent than in non-abused populations.
Risk of subsequent psychiatric disorders: PTSD, major depression, agoraphobia, OCD, social phobia, simple phobia. The childhood abuse-adult abuse link is complex - childhood abuse as a risk factor worsens all sequelae of adult abuse.
Protective factor: Social support is the most important protective factor in ameliorating trauma-related symptoms. Its absence or perceived social marginalisation significantly worsens outcomes.

APPROACH TO THE VICTIM
1. Triage and Immediate Priorities
Sexual assault patients should be triaged as high priority per Department of Justice recommendations. Place the patient in a private room (ideally dedicated to sexual assault care). Notify the Sexual Assault Nurse Examiner (SANE) or Sexual Assault Forensic Examiner (SAFE) on call. Instruct the patient not to undress, wash, eat, drink, or rinse the mouth - all clothing must be stored as forensic evidence.
2. Establishing the Therapeutic Environment
Begin with introductions and an expression of regret about the assault. Maintain a professional, non-judgmental, caring attitude. Key principles:
- A physician's shock or outrage increases the patient's concern or feelings of marginalisation
- Questions perceived as critical or judgmental generate guilt and shame, interfering with history-taking
- Allow the patient to direct the pace and content of the interview - the crime may have been a time of powerlessness, and recapitulating that dynamic can trigger traumatic responses
- Remain attuned to nonverbal cues of discomfort
- This early therapeutic contact may positively influence long-term prognosis
3. History Taking
Open-ended questions should be used. Obtain:
- Detailed assault description (type of assault, weapons used, orifices involved, condom use, patient's activities since assault - bathing, changing, urinating)
- Past medical and gynaecological history (LMP, contraception, prior STDs, baseline injuries)
- Whether injuries occurred and their location
- Any drug or alcohol ingestion (important for drug-facilitated assault)
Critical time point: Forensic evidence collection is viable within 72 hours (some states allow up to 96 hours). However, medical treatment (STI prophylaxis, emergency contraception, injury management) should be provided regardless of forensic examination consent.
4. Consent
Obtain written informed consent for:
- Forensic examination
- Evidence collection
- Photography
- Transfer of evidence to law enforcement
Patients have the right to refuse any component of the examination. Medical care is provided irrespective of consent to forensic examination or police reporting.
5. Physical Examination - Systematic Approach
General Examination:
- Full vital signs and mental status assessment
- Head-to-toe inspection after properly removing and storing clothing
- Focus on defensive injury areas (extremities) and common injury sites: oral cavity, neck (strangulation signs), breasts, thighs, buttocks
- Document all injuries using a body diagram/clock face reference (in lithotomy position: pubic bone = 12 o'clock, left hip = 3 o'clock, right hip = 9 o'clock)
- Describe location, size, shape of each injury; photograph if possible
Genital Examination:
- Comb pubic hair and collect samples (including hair root)
- Examine genital and rectal areas for injuries, discharge, abrasions, lacerations
- Toluidine blue dye can be applied to the external vulva (not mucous membranes) to highlight microtrauma - it has affinity for DNA/RNA and highlights areas where the superficial non-nuclear layer has been removed by injury. Use before speculum examination to avoid confusion with iatrogenic abrasions.
- Colposcopy detects injuries not visible to the naked eye (one study: 34% visible naked eye; 49% with colposcopy; 52% with toluidine blue)
- If anal penetration is reported, examine anus and rectum for abrasions or lacerations
- Wood's lamp examination in a darkened room to detect traces of semen; swab all areas of oral contact and fluorescent areas
Chain of Custody: All collected evidence must be maintained under strict chain of custody. Do not leave the rape kit unattended. Each handover must be signed, dated, and timed. Store in a locked, refrigerated cabinet if police are unavailable.
- Tintinalli's Emergency Medicine, p. 2009-2012
6. Laboratory Investigations
-
STI testing: NAAT for gonorrhoea and chlamydia (cervical, pharyngeal, rectal as appropriate), wet preparation for bacterial vaginosis and trichomonas, syphilis serology
-
Pregnancy test (urine or serum hCG)
-
HIV baseline serology
-
Hepatitis B status
-
Drug-facilitated assault: special urine toxicology for ketamine, flunitrazepam (Rohypnol - detectable up to 72 hours), gamma-hydroxybutyric acid/GHB (detectable only up to 12 hours) - these are NOT detected on routine ED toxicology screens; specific send-out tests are required
-
Tintinalli's Emergency Medicine, p. 2012
7. Prophylaxis and Medical Treatment
Emergency Contraception:
- Levonorgestrel (Plan B) within 72 hours (up to 120 hours with reduced efficacy)
- Ulipristal acetate within 120 hours
- Copper IUD within 5 days (most effective option)
STI Prophylaxis:
- Ceftriaxone 500mg IM (or 1g if weight >150kg) for gonorrhoea
- Doxycycline 100mg BD x 7 days or azithromycin 1g single dose for chlamydia
- Metronidazole 2g single dose or 500mg BD x 7 days for BV/trichomonas
- Hepatitis B vaccination if non-immune
- HIV post-exposure prophylaxis (PEP): Should be offered when there is significant exposure risk; initiated within 72 hours, continued for 28 days (e.g., tenofovir/emtricitabine + raltegravir or dolutegravir)
Injury management: Treat acute injuries as clinically indicated. Refer surgical injuries appropriately.
8. Safety Assessment
After any assault (physical or sexual), conduct a formal safety assessment:
- Assess for suicidal and homicidal ideation directly related to the assault
- Assess safety from further assault (particularly if perpetrator is an intimate partner or known acquaintance)
- Screen for severe psychological symptoms: acute mood deterioration, affective instability, self-destructive behaviours, dissociation, psychosis
- Develop a safety plan: safe place to sleep, eat, recuperate; plan for absence from home/work
Indications for Hospitalisation:
- Severe medical injuries requiring inpatient care
- Active suicidality or homicidality
- Dissociative or psychotic symptoms
- Mood instability or affective dysregulation
- Self-destructive behaviours
- Continued serious threat to patient's life or wellbeing
An individualised, multidisciplinary treatment plan must be developed if admitted.
- Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7946
9. Legal and Mandatory Reporting
-
Mandatory reporting requirements vary by jurisdiction
-
Child, elder, and developmentally disabled abuse requires mandatory reporting in all 50 US states
-
Domestic violence between adults does not universally require mandatory reporting, but serious injuries from criminal violence often do (de facto mandatory reporting)
-
Document all findings thoroughly in the medical record for future legal purposes
-
Chain of custody for forensic evidence must be maintained rigorously
-
The forensic examination aims to document history and physical findings and collect evidentiary material - it does not determine whether rape occurred; final documentation should avoid legally conclusive language
-
Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7946
10. Psychological Interventions
Acute Phase:
- Psychological first aid: validation, normalisation of responses, emotional support
- Avoid victim-blaming language or attitudes
- Crisis intervention techniques
Post-Assault Psychotherapy:
- Cognitive Behavioural Therapy (CBT) is the most well-researched intervention with demonstrated efficacy
- Trauma-focused CBT (TF-CBT): Accelerates recovery in acute PTSD
- Exposure therapy (a CBT variant): Helps victims emotionally process the assault by reducing fear of assault-related memories/cues; decreases avoidance
- Eye Movement Desensitisation and Reprocessing (EMDR): Evidence-based for trauma processing
- Pharmacotherapy: SSRIs (e.g., sertraline, paroxetine) are first-line for PTSD; address comorbid depression, anxiety, insomnia as indicated
- Address substance abuse if present
Ongoing Support:
-
Referral to rape crisis centres, support groups
-
RAINN (Rape, Abuse & Incest National Network): 800-656-HOPE - national resource
-
Ensuring continuity from inpatient to outpatient care
-
Follow-up appointments at 1 week (for those on PEP/STI treatment) and 1-2 weeks for all patients
-
Kaplan & Sadock's Comprehensive Textbook of Psychiatry, p. 7947-7948
-
Tintinalli's Emergency Medicine, p. 2012
SPECIAL POPULATIONS
Elder Abuse
- Physical, sexual, emotional, financial, or neglect
- Most elder sexual assaults occur at the patient's home
- Forensic examination is challenging due to: hip contractures, vaginal atrophy, cognitive impairment/dementia (difficulty obtaining accurate history)
- ACOG recommends routine assessment of all patients >60 years for signs of elder abuse, including "Do you feel safe at home?"
- May be reportable to Adult Protection Services depending on state law
Male Victims of Sexual Assault
- Less commonly reported; resources for counselling are more limited, especially in smaller communities
- SANE/SAFE examiners are trained in forensic examination of males
- Rectal/anal examination is important
- Follow-up with urology or proctology recommended
- RAINN provides resources for male survivors
Transgender and Lesbian Patients
- 47% of transgender women report being raped at least once in their lifetime
- Cultural competence and affirming care are essential
- Tailor examination and history-taking to the individual's anatomy and identity
Drug-Facilitated Sexual Assault
-
"Date rape drugs": Rohypnol (flunitrazepam), GHB (gamma-hydroxybutyric acid), ketamine
-
These are NOT detected on routine toxicology screens
-
Must order specific send-out urine tests within the detection window
-
GHB is only detectable for 12 hours; Rohypnol for up to 72 hours
-
Tintinalli's Emergency Medicine, p. 2011-2014
-
Berek & Novak's Gynecology, p. 1017
SCREENING AND PREVENTION
- ACOG recommends routine screening for sexual abuse history in all female patients ("Has anyone ever forced you to have sexual relations?")
- Domestic violence screening tools (e.g., HITS, AAS) should be incorporated into routine primary care and emergency encounters
- Trauma-informed care principles should be applied across all settings
- All patients should be screened privately (without partner present)
- When domestic violence is disclosed, it must be documented in the chart for follow-up and potential future legal documentation
