COUN5420 develops the diagnostic competency required to identify, conceptualize, and plan treatment for psychological disorders in children and adolescents. Diagnosing young people is fundamentally different from adult diagnosis: developmental context determines whether a behavior is pathological or normative, symptom presentation shifts dramatically across developmental stages, and the family and school environments shape both the expression and the recognition of symptoms. This course builds the developmentally informed diagnostic knowledge that clinical mental health counselors need.
What COUN5420 covers
Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed neurodevelopmental disorder in children and the disorder most frequently encountered in COUN5420. The DSM-5-TR specifies three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. Inattentive presentation manifests as difficulty sustaining attention, not listening when spoken to, difficulty organizing tasks, losing materials, and being easily distracted. Hyperactive-impulsive presentation manifests as fidgeting, leaving seat, running or climbing inappropriately, difficulty playing quietly, and acting as if "driven by a motor." Symptoms must be present in two or more settings (home and school), must have been present before age 12, and must cause clinically significant impairment in social, academic, or occupational functioning. Understanding how to distinguish ADHD from normative childhood energy, anxiety-driven inattention, trauma responses that mimic ADHD, and sleep deprivation is a critical diagnostic skill.
Anxiety disorders in children include separation anxiety disorder (excessive anxiety about separation from attachment figures), generalized anxiety disorder (chronic worry about multiple domains), social anxiety disorder (intense fear of social evaluation), specific phobias, and selective mutism. Depression in children and adolescents presents differently from adult depression: irritability is a primary mood symptom (rather than sadness alone), somatic complaints are common, and developmental context shapes the expression — school refusal, social withdrawal, declining academic performance, and behavioral acting out may be the presenting features rather than the sad mood and cognitive symptoms that define adult major depressive disorder.
Autism spectrum disorder (ASD) is examined across the severity spectrum, with attention to how diagnostic assessment differs from screening, how level-of-support designations affect service planning, and how ASD intersects with other diagnoses (ADHD, anxiety, intellectual disability). Conduct disorder and oppositional defiant disorder (ODD) are examined within the developmental framework that distinguishes normative adolescent defiance from clinically significant patterns of aggression, rule violation, and disregard for others' rights, and within the social context that recognizes how poverty, trauma, and systemic marginalization contribute to conduct problems.

Common writing assignments in COUN5420
Diagnostic case conceptualization
Students analyze a case study of a child or adolescent presenting with psychological symptoms, apply DSM-5-TR diagnostic criteria to determine the appropriate diagnosis, conduct differential diagnosis (ruling out alternative explanations for the symptoms), identify developmental factors that inform the diagnostic picture, and propose an evidence-based treatment plan. Strong conceptualizations explicitly address why alternative diagnoses were considered and ruled out — a child referred for ADHD evaluation whose symptoms are better explained by anxiety requires the conceptualization to document the diagnostic reasoning that distinguished anxiety-driven inattention from ADHD.
Disorder analysis paper
Students produce a comprehensive analysis of a specific child/adolescent disorder — covering DSM-5-TR diagnostic criteria, prevalence and demographics, etiology (genetic, neurobiological, environmental, developmental risk factors), developmental presentation across ages, differential diagnosis, comorbidity patterns, and evidence-based treatment approaches. Papers must address developmental considerations explicitly: how the disorder manifests differently in a 6-year-old than in a 15-year-old, and what treatment adaptations are required for different developmental stages.
Discussion posts
Posts address diagnostic scenarios: a teacher referring a 7-year-old Black boy for ADHD evaluation based on classroom behavior that may reflect trauma response rather than ADHD, a 14-year-old girl whose declining grades and social withdrawal are attributed to "typical teenage behavior" but may represent major depressive disorder, a 4-year-old whose rigidity and intense interests are raising questions about ASD vs. normal preschool behavior, or a 16-year-old whose substance use and conduct problems mask underlying PTSD.

Writing tips for COUN5420
Always address differential diagnosis
Every COUN5420 diagnostic case conceptualization must explicitly address differential diagnosis — the process of distinguishing the correct diagnosis from alternative diagnoses that present with similar symptoms. ADHD inattentive presentation, anxiety disorder, and PTSD can all present as a child who cannot focus, does not follow instructions, and has declining academic performance. Conduct disorder and PTSD can both present as an aggressive, defiant adolescent. Depressive disorder and normal grief can both present as a withdrawn, tearful child after a loss. The diagnostic analysis must identify the specific clinical features that distinguish the correct diagnosis from the alternatives, referencing the DSM-5-TR diagnostic criteria for each. Papers that assign a diagnosis without conducting differential diagnosis do not demonstrate the diagnostic reasoning competency the course develops.
Address the developmental context of every symptom
Child psychopathology papers must contextualize every symptom within the child's developmental stage. A 5-year-old who has an imaginary friend is engaging in normative play; a 12-year-old who insists an imaginary person is real may be experiencing psychotic symptoms. A 2-year-old who has tantrums is developmentally normative; a 7-year-old who has explosive tantrums three times daily may meet criteria for ODD. A 14-year-old who is moody and tests boundaries is developmentally normal; a 14-year-old who is persistently irritable, socially withdrawn, and expressing hopelessness may be experiencing major depressive disorder. Every symptom must be evaluated against the question: is this behavior outside the range of normative behavior for this child's age and developmental stage? Papers that apply adult diagnostic frameworks without developmental adaptation are diagnostically inaccurate.

Frequently asked questions
ADHD and anxiety can both produce inattention, difficulty completing tasks, restlessness, and academic underperformance, making differential diagnosis essential. Key distinguishing features: ADHD inattention is pervasive — the child is consistently inattentive across settings, not specifically when worried about something. Anxiety-driven inattention is content-specific — the child cannot focus because they are preoccupied with worry, and the inattention worsens in anxiety-provoking situations but may be absent when the child is relaxed and engaged. ADHD hyperactivity is purposeless motor activity (fidgeting, squirming, running); anxiety-driven restlessness is tension-related (nail-biting, leg-bouncing, needing reassurance). ADHD is typically worse in low-stimulation, boring situations; anxiety is worse in high-demand, evaluative situations. Children with ADHD often seek stimulation impulsively; anxious children often avoid stimulation. Comorbidity is common — approximately 25-30% of children with ADHD also have an anxiety disorder — so both diagnoses may be accurate simultaneously.
The DSM-5-TR allows irritable mood (rather than only depressed mood) as a primary mood symptom for children and adolescents — this is the most important developmental adaptation. A child presenting with persistent irritability, anger outbursts, and oppositional behavior may be experiencing major depressive disorder. Other developmental differences: children with depression may present with somatic complaints (stomachaches, headaches) rather than articulating sadness. School refusal and declining academic performance may be primary presenting features. Social withdrawal may manifest as reduced play activity in younger children. Behavioral regression (returning to earlier developmental behaviors) may occur. In adolescents, depression may present as substance use, risk-taking behavior, or interpersonal conflict rather than classic depressive symptoms. These developmental adaptations are critical for COUN5420 diagnostic papers — applying adult depression criteria without developmental modification leads to underdiagnosis in children and adolescents.
ODD and CD are both disruptive behavior disorders, but they differ in severity and behavior type. ODD involves a pattern of angry/irritable mood (frequent temper outbursts, touchy or easily annoyed, angry and resentful), argumentative/defiant behavior (argues with authority figures, actively defies or refuses rules, deliberately annoys others, blames others for mistakes), and vindictiveness. ODD behaviors are primarily relational and oppositional but do not involve the violation of others' rights or major societal norms. Conduct disorder involves more severe behaviors in four categories: aggression toward people and animals (bullying, fighting, weapon use, physical cruelty), destruction of property, deceitfulness or theft, and serious rule violations (truancy, running away, staying out late despite prohibitions). CD is a more serious diagnostic category and is developmentally subtyped: childhood-onset (before age 10, associated with more severe and persistent patterns) vs. adolescent-onset (after age 10, often associated with peer influence and better prognosis). The callous-unemotional traits specifier identifies a subgroup at highest risk for persistent antisocial behavior.
The DSM-5-TR classifies ASD severity using three levels based on the degree of support needed. Level 1 ("Requiring support") describes individuals who, without support, show noticeable social communication deficits — difficulty initiating social interactions, atypical or unsuccessful responses to social overtures, apparent decreased interest in social interactions — and restricted/repetitive behaviors that interfere with functioning in some contexts. Level 2 ("Requiring substantial support") describes individuals with marked deficits in verbal and nonverbal social communication, limited social interactions even with support, and restricted/repetitive behaviors that are frequent enough to be obvious and interfere with functioning across multiple contexts. Level 3 ("Requiring very substantial support") describes individuals with severe social communication deficits, very limited initiation and minimal response to social overtures, and restricted/repetitive behaviors that markedly interfere with all domains of functioning. These levels are assessed separately for social communication and restricted/repetitive behaviors, as a child might have different support needs in each domain.
