2.4 Mental and Behavioral Health Screening Tools
Key Takeaways
- The PHQ-A (Patient Health Questionnaire for Adolescents) screens for depressive severity; any positive response to Item 9 (suicidal ideation) mandates immediate crisis safety evaluation.
- The GAD-7 measures adolescent anxiety severity (cut-off scores of 5, 10, and 15 represent mild, moderate, and severe anxiety, respectively).
- The CRAFFT screening tool evaluates adolescent substance misuse risks; a score of 2 or higher indicates high risk warranting Brief Intervention (SBIRT) and specialized referral.
- School nurses are legally mandated reporters required to notify Child Protective Services (CPS) immediately upon reasonable suspicion of child abuse or neglect without waiting for proof.
- Interdisciplinary referral workflows utilize Multi-Tiered System of Supports (MTSS) to seamlessly connect screened students with school psychologists, social workers, and community mental health services.
School Nurse Role in Mental & Behavioral Health Screening
School nurses occupy a vital position on the frontlines of student behavioral health. With over 20% of K-12 students experiencing a diagnosable mental health condition, school nurses utilize validated, standardized screening tools to identify depression, anxiety, substance use disorders, trauma, and child abuse early—before academic failure or crisis occurs.
Validated Mental Health Screening Instruments
Screening in schools must be evidence-based, developmentally appropriate, and conducted in environments that protect student privacy and promote trauma-informed care.
1. PHQ-A (Patient Health Questionnaire for Adolescents)
- Target Population: Adolescents ages 11–18.
- Construct: Assesses frequency of DSM-5 depressive symptoms over the preceding 2 weeks.
- Scoring Categories:
0 – 4: Minimal or no depression5 – 9: Mild depression10 – 14: Moderate depression15 – 19: Moderately severe depression20 – 27: Severe depression
IMMEDIATE CRISIS SAFETY RULE (Item 9): Item 9 asks about thoughts of suicide or self-harm. Any score $> 0$ on Item 9 requires immediate, same-day suicide risk assessment, student supervision, and activation of school crisis safety protocols.
2. GAD-7 (Generalized Anxiety Disorder 7-Item Scale)
- Target Population: Students ages 11 and older.
- Construct: Measures anxiety symptom severity over the preceding 2 weeks.
- Cut-Off Thresholds: Scores of 5 (Mild), 10 (Moderate), and 15 (Severe). Scores $\ge 10$ indicate clinical significance requiring referral for cognitive behavioral or psychiatric evaluation.
3. PSC-17 (Pediatric Symptom Checklist 17-Item Version)
- Target Population: Children ages 4–18 (completed by parent or self-reported by older youth).
- Construct: Brief screening tool evaluating three subscales: Internalizing (depression/anxiety), Externalizing (conduct/behavioral), and Attention (ADHD symptoms).
- Scoring Threshold: An overall score of $\ge 15$ (or subscale scores $\ge 5$ for internalizing, $\ge 7$ for externalizing, $\ge 7$ for attention) indicates a positive screen requiring comprehensive behavioral health evaluation.
CRAFFT Screening Tool for Adolescent Substance Use
The CRAFFT instrument is the gold-standard screening tool recommended by the American Academy of Pediatrics for adolescent alcohol and substance misuse.
CRAFFT Part B Mnemonic Questions
| Letter | Mnemonic Prompt Question |
|---|---|
| C | Have you ever ridden in a CAR driven by someone (including yourself) who was "high" or had been using alcohol or drugs? |
| R | Do you ever use alcohol or drugs to RELAX, feel better about yourself, or fit in? |
| A | Do you ever use alcohol or drugs while you are by yourself, ALONE? |
| F | Do you ever FORGET things you did while using alcohol or drugs? |
| F | Do your family or FRIENDS ever tell you that you should cut down on your drinking or drug use? |
| T | Have you ever gotten into TROUBLE while you were using alcohol or drugs? |
CRAFFT Scoring & SBIRT Clinical Workflow
- Score 0: Reinforce positive healthy choices; provide primary prevention education.
- Score $\ge 2$: Indicates high risk for a substance use disorder or significant substance-related harm. Triggers SBIRT (Screening, Brief Intervention, and Referral to Treatment) protocol and referral to adolescent addiction specialists.
Child Abuse, Neglect, & Trauma Indicators
School nurses have an ethical and absolute statutory obligation as Mandated Reporters.
Physical & Behavioral Indicators of Abuse / Neglect
- Physical Abuse: Unexplained or patterned bruises (belt marks, handprints, loop marks), burns in specific shapes (cigarette burns, immersion glove/stocking burns), fractures in varying stages of healing, injuries on non-bony prominences (torso, neck, ears).
- Sexual Abuse: Difficulty walking or sitting, stained or bloody undergarments, sudden onset of enuresis/encopresis, age-inappropriate sexual knowledge or behaviors, genital trauma or STI acquisition.
- Physical Neglect: Chronic unwashed hygiene, inappropriate clothing for weather (e.g., wearing t-shirt in sub-zero temperature), severe untreated medical/dental problems, chronic hunger or hoarding food, severe unexcused absenteeism.
- Trauma/PTSD Indicators: Hypervigilance, exaggerated startle response, sudden academic drop, withdrawal, somatic complaints (stomachaches, headaches) prior to school.
Mandated Reporting Legal Standards
- Reasonable Suspicion Standard: The school nurse is legally required to file a report with Child Protective Services (CPS) or law enforcement upon reasonable suspicion of abuse or neglect. The nurse does NOT investigate or gather evidence to prove abuse.
- Immediate Reporting: Reports must be filed immediately by phone, followed by written documentation within state-mandated timelines (typically 24–48 hours).
- Employer Immunity: Mandated reporters acting in good faith are immune from civil or criminal liability.
Interdisciplinary Referral Workflows (MTSS Framework)
Mental health integration utilizes the Multi-Tiered System of Supports (MTSS) framework:
- Tier 1 (Universal): Universal screening (e.g., school-wide wellness checks), socio-emotional learning (SEL) curricula, anti-bullying initiatives.
- Tier 2 (Targeted): Small group intervention, nurse-led stress management, school counselor check-ins for moderate GAD-7 or PHQ-A scores.
- Tier 3 (Intensive): Crisis intervention for suicidal ideation, individualized re-entry plans after psychiatric hospitalization, referral to external community mental health agencies, wrap-around services.
A 16-year-old high school student completes the PHQ-A depression screening tool in the health office. The student scores a total of 12, but scores a '2' on Item 9 ('thoughts that you would be better off dead or of hurting yourself'). What is the school nurse's mandatory priority intervention?
An adolescent student completes the CRAFFT substance use screening tool and receives a score of 3. How should the school nurse interpret this score and proceed with clinical management?
While conducting a physical assessment on a 7-year-old student, the school nurse identifies distinct, parallel loop-shaped bruises across the lower back and thighs. The child remains withdrawn and mute when asked about the marks. What is the nurse's legal responsibility?
On the Pediatric Symptom Checklist (PSC-17), which total cutoff score indicates a positive screen requiring further interdisciplinary behavioral health evaluation?
