Anxiety in Childhood and Adolescence – Comprehensive Notes

Focus and objectives

• Topic: Anxiety in childhood and adolescence; overview of anxiety and anxiety disorders in children, etiology and models, assessment, and intervention approaches (CBT and ACT).
• Learning objectives:
  • Understand differences between developmentally appropriate fear, worry, and anxiety disorders.
  • Recognize and identify anxiety disorders in children and adolescents.
  • Understand models of anxiety and their application to case formulation.
  • Understand approaches to assessing anxiety in children and adolescents.
  • Describe broad CBT and ACT approaches to intervention.

Distinction: fear vs. anxiety and developmentally appropriate fear

• Fear vs. anxiety (key distinction):
  • Fear: short-term physiological response to a stressor, usually immediate threat.
  • Anxiety: apprehension that can build slowly, linger, often about future events; shares symptoms with fear but is future-oriented.
• Both fear and anxiety can be present across typical development; problems arise when excessive or inappropriate, crossing into disorders.
• Developmental perspective: normal fears rise and fall with age; understanding typical fears helps differentiate abnormality.

Developmental overview: typical fears by age (developmental table highlights)

• Infancy (0–6 months): sensory over-responsivity; fears related to loud noises; loss of support; strong sensory stimuli.
• Late infancy (6–12 months): cause/effect understanding; object constancy; fears of strangers and separation from caregiver; attachment dynamics.
• Toddler (2–4 years): preoperational thinking; fears of imaginary creatures, dark, burglars; early separation anxiety; risk of evolving into anxiety disorders like separation anxiety or selective mutism.
• Early childhood (5–7 years): concrete operational thinking; fears around natural disasters, injuries, animals, media; phobias may emerge.
• Middle childhood (8–11 years): self-esteem tied to school performance and peer interactions; fears around tests, academics, athletics; school phobia and test anxiety may appear.
• Adolescence: formal operational thought; anticipation of future dangers; heightened concern with peer relationships and self-esteem; fears around peer rejection, bullying; social phobia, agoraphobia, and panic disorder can emerge.
• Note: normalization varies by culture; cultural context influences what is considered typical or atypical.

Anxiety disorders in DSM-5 (covered here)

• Disorders discussed: Separation Anxiety Disorder, Selective Mutism, Specific Phobia, Social Anxiety Disorder, Generalized Anxiety Disorder.
• Common factors across disorders:
  • Disturbance and anxiety symptoms
  • Clinically significant distress or impairment in functioning (academic, social, family, occupational)
  • Symptoms not better explained by another mental health disorder

Separation Anxiety Disorder (SAD)

• Core criterion: excessive and age-inappropriate fear of separation from the primary caregiver.
• Diagnostic threshold: at least 3 of the following, present for ≥ 4\,\text{weeks} in children:
  • Distress about or fear of separation from caregiver
  • Excessive worry about losing caregiver to illness or death
  • Worry about events that would separate them from caregiver (getting lost, kidnapping, etc.)
  • Reluctance to be away from caregiver for sleepovers, school, or other activities
  • Recurrent nightmares involving separation
  • Physical symptoms (headache, stomachache) when separated
• Prevalence: about 4\%; more common in children than adolescents; more common in girls; prevalence not strongly tied to race/ethnicity but culture matters (norms around separation vary).
• Differential considerations: differentiate from GAD (GAD is broader worry not solely about separation), panic or agoraphobia, PTSD (fear relates to trauma), social anxiety (fear of social evaluation), and Selective Mutism.

Selective Mutism

• Definition: routine failure to speak in at least one setting despite ability to speak in other settings.
• Duration: at least 1\text{ month} (not limited to the first month of a new school context).
• Important exclusion: not due to language barriers or communication disorders; must have ability to speak in some settings.
• Co-occurrence: social anxiety can co-occur with selective mutism.
• Prevalence: < 1\%; more common in girls; racial/SES differences unclear.

Specific Phobia

• Definition: persistent, excessive fear of a specific object or situation that is avoided or endured with marked distress.
• Common features in children: tantrums, crying, clinging, freezing; frequent somatic complaints (e.g., stomachaches).
• Criteria for phobia: fear is disproportionate to actual danger and leads to impairment.
• Common content: animals, natural environment (storms, heights), blood/injury, situational (elevators, airplanes, hand dryers/bathrooms), vomiting, clowns, etc.
• Prevalence: 4\%–16\%; higher in adolescence than in children; more common in girls; culture can shape fear content.
• Differential considerations: differentiate from agoraphobia (fear of leaving home across multiple situations) and from specific phobias that focus on a single situation.

Social Anxiety Disorder (Social Phobia)

• Core feature: extreme fear of being negatively evaluated in social or performance situations.
• In children: fears typically in settings with peers; may present as tantrums, freezing, crying, clinging, shaking, or not speaking.
• Criteria: recurrent fear in social or performance situations, nearly always triggers fear, avoidance or extreme distress, and impairment; duration of symptoms ≥ 6\,\text{months}.
• Prevalence: about 7\%–8\%; more common in adolescents than children; more common in girls.
• Distinctions: separate from normative shyness; differentiate from autism spectrum presentations by observing social communication across contexts and with caregivers; in autism, social impairment persists across settings including with caregivers.

Generalized Anxiety Disorder (GAD)

• Core feature: excessive worry about multiple domains (not limited to a single fear).
• Criteria (children): worries most days for at least 6\text{ months} and difficulty controlling worry, plus at least one of the following symptoms: restlessness, fatigue, trouble concentrating, irritability, muscle tension, sleep disturbance; symptoms not explained by a medical condition or substance.
• Prevalence: about 1\%; more common in adolescents; more common in girls; slightly higher in middle/high SES groups.

Differential diagnosis and cross-cutting considerations

• Distinguish disorders by the focus of the fear/content and the primary trigger (e.g., separation from caregiver vs. negative evaluation in social contexts).
• Panic attacks can appear in SAD or Social Anxiety Disorder, but the focus of fear remains central to SAD or social evaluation rather than separation.
• PTSD and depression may involve anxiety, but the content and context (trauma memories; depressive symptoms) differentiate them from primary anxiety disorders.
• Cultural considerations: content and expression of fears vary across cultures; clinicians should be sensitive to cultural norms around separation, social behavior, and stigma.

Etiology and models of anxiety (biopsychosocial framework)

• Overall view: anxiety arises from a complex interplay of biological, psychological, and social factors.

Biological theories

• Genetic vulnerability: about 30\% of variance in anxiety is accounted for by genetic factors; shared environment accounts for about 20\%.
• Neurotransmitter hypotheses: dysregulation of noradrenergic, GABAergic, and serotonergic systems underpin anxiety; pharmacological treatments (SSRIs, TCAs, benzodiazepines) can help some youth, but evidence is limited and often supplemented by behavioral/psychological interventions.
• Temperamental factors: behaviorally inhibited temperament predisposes to anxiety; associated with higher limbic/sympathetic arousal; risk factor for later anxiety disorders.
• Pharmacological note: while pharmacotherapy can be helpful for some cases, there is greater emphasis on behavioral and cognitive-behavioral interventions in childhood.

Psychological theories

• Psychoanalytic (psychodynamic) theory:
  • Anxiety arises from defense mechanisms that displace unacceptable impulses into phobic objects; treatment via psychodynamic play therapy in children or individualized psychodynamic therapy in adolescents.
  • Aim to interpret the defense and the hidden feelings and connect the therapist relationship with family/peer dynamics (triangle of conflict).
• Beck’s cognitive theory:
  • Threat-oriented cognitive schemas formed in early life lead to threat-sensitive thinking and distortions (minimizing safety-focused events; magnifying threat).
  • CBT targets monitoring and challenging distorted cognitions.
• Incubation theory (behavioral):
  • Fear develops through a conditioned association; repeated brief exposure can increase fear via incubation; explains the persistence of fear with certain phobic objects.
  • Intervention: gradual exposure (in vivo or imagery), relaxation, and coping strategies.
• Behavioral theory and exposure: the incubation process is countered by gradual exposure to the feared object/situation until habituation.

Family systems theory

• Parental modeling and family interactions shape anxious responses; family life cycles and stress can precipitate and maintain anxiety disorders.
• Therapy often involves family work to support the child and to change interaction patterns that reinforce avoidance.
• Key points:
  • Many parents of anxious children have their own anxiety disorders; modeling and parenting styles influence transmission.
  • Stressful life events and marital discord can contribute to onset in some children.

Integrated biopsychosocial model

• Predisposing factors: personal (genetic vulnerability, temperament, self-esteem, locus of control) and contextual (attachment quality, parental anxiety, threat-focused family, culture).
• Precipitating factors: acute life events, illness, bullying, abuse, parental separation, school transitions, births, bereavement, moving, unemployment.
• Maintaining factors and protective factors: personal (coping strategies, attributional style) and contextual (family support/coordination, treatment system engagement).
• Implication for formulation and intervention: assess across child, family, school, and peer contexts; target multiple interacting factors in treatment.

Formulation framework (clinical practice)

• Always frame the child within their context: family dynamics, school environment, peer relationships.
• Identify ongoing triggers, functional role of anxiety, and what maintains symptoms.
• Use biopsychosocial lens to guide intervention planning (which factors to target first).

Assessment of anxiety in children and adolescents

Methods of assessment (three broad techniques)

• Clinical interview (semi-structured options):
  • Anxiety Disorder Interview Schedule for Children (child and parent versions).
  • Structured interviews provide DSM-based diagnoses; can align with DSM-5 criteria.
  • Example: Hamilton Anxiety Rating Scale to rate global, psychic, and somatic anxiety after interview.
• Self-report measures (child/adolescent versions): a range of scales with varying length (e.g., 26–45 items; choose by age, reading level, and targetConstruct).
• Parent/teacher ratings: critical to capture behavior across contexts; cross-informant discrepancies can illuminate family dynamics or context-specific issues.

Common assessment tools (examples from the slides)

• School refusal assessment scale
• Child Behavior Checklist (CBCL) – broad symptom check with parent, teacher, and self-report forms
• Behavior Assessment System for Children (BASC) – broad symptom coverage; forms for different reporters
• Strengths and Difficulties Questionnaire (SDQ) – broad screening with self, parent, and teacher versions
• Children's Mood, Fears, and Worries Questionnaire – parent-rated internalizing difficulties

Monitoring and functional assessment in treatment planning

• Subjective units of distress (SUDS) and child-friendly adaptations:
  • Bubble up procedure (rating bubbles) to build anxiety/hierarchy foundations.
  • Track My Fears: identify cognitive, emotional, interpersonal, physiological, and behavioral components of fear.
  • Fear thermometer: rate current fear from 0 to 10; informs exposure planning.
  • Feelings thermometer: measure overall affect from very bad to very good.
  • Daily feelings records: date, context, and situational factors; track progress over time.
  • Anxious feelings learning activities: physical exercises to observe arousal (head movements, jumping jacks, etc.) to connect body and fear.
  • Body maps: locate where anxiety is felt in the body; promote somatic awareness.
  • Thought bubbles: record anxious thoughts; link thoughts to bodily sensations and behaviors.
• Functional Behavioral Assessment (FBA): evaluate the function of anxiety-related behaviors (antecedents, behaviors, consequences – ABCs).
  • Indirect methods: interviews, checklists from child/parents/teachers.
  • Direct methods: observation, ABC charts, scatter plots, time-sampling; home visits.
  • Purpose: identify drivers (e.g., bullying, separation, academic demands) and guides intervention planning and collaboration with schools.
• When to use FBA: especially useful for school refusal and classroom-related anxiety; informs collaboration with school and other professionals.

Practical considerations in assessment

• Balance child self-report with parent/teacher reports; discrepancies can reveal family dynamics or differing perspectives.
• Cultural/contextual factors influence presentation and interpretation of anxiety; adapt assessment and intervention accordingly.

Intervention approaches for anxiety (brief overview)

General principles of intervention for children’s anxiety

• Psychoeducation: teach about anxiety, its functions, and treatment process.
• Symptom monitoring: establish reliable tracking of symptoms and triggers.
• Relaxation and breathing skills: teach calming techniques to reduce physiological arousal.
• Cognitive restructuring: challenge threat-oriented thoughts and distortions; develop adaptive thinking.
• Exposure and habituation: systematic exposure to feared stimuli; gradual, repeated, and supported exposure to reduce fear.
• Reinforcement and motivation: reward engagement in exposure and practice; build adherence.
• Family involvement: essential for younger children; family training to support the child and modify reinforcement patterns.
• School involvement: coordinate with school if anxiety affects schooling; obtain teacher support and accommodations if needed.
• Collaboration with other professionals: liaise with pediatricians, speech-language pathologists, OTs, etc.
• For parents: provide support and skills to manage their own anxiety and reactions; family-wide changes support child progress.

Specific intervention frameworks

• Cognitive Behavioral Therapy (CBT) sequence (general CBT framework for pediatric anxiety):
  • Self-monitoring and psychoeducation
  • Simple interventions: relaxation, systematic desensitization, social skills training, self-instruction, anxiety prediction, decatastrophizing
  • Exposure/habituation to feared stimuli
  • Maintenance strategies and relapse prevention
• Modular Approach (Torpey & Weiss, modular approach to therapy for pediatric anxiety):
  • Assess where the child is, what barriers exist, and select modules accordingly (e.g., mood, social skills, exposure, conduct problems, trauma)
  • Flexible, individualized sequencing; no single path fits all
  • Provides data-driven decisions about progress and barriers (e.g., if interference due to conduct problems, apply time-out or active ignoring; if mood-related, address depressive thoughts or somatic arousal)
• Exposure techniques
  • Create an exposure hierarchy (fear ladder) linked to the fear/SAUs (subjective units of distress)
  • Use red-yellow-green stoplight framework to categorize exposure tasks by difficulty and tolerance
  • False alarms vs true alarms: train child to distinguish between unfounded fears and real risks
  • Use data-driven exposure to promote habituation and belief in coping abilities
• Relaxation and physiological interventions
  • Progressive muscle relaxation, diaphragmatic breathing, and other calming strategies
  • Used to reduce arousal before/during exposure
• Social skills training
  • Public role-plays, coping strategies for teasing, and modeling of adaptive social behavior
• Cognitive self-instruction and evaluation
  • Teach internal dialogue to challenge fear-based thoughts; differentiate between real and imagined threats; test beliefs with evidence
• Behavioral activation and problem-solving
  • Build coping strategies for daily challenges; promote engagement in pleasant activities despite anxiety
• Rewards and motivation systems
  • Use badges of courage, tokens, or other rewards to promote adherence to exposure tasks

DNAV model (ACT-based approach for youth)

• DNAV stands for Discoverer, Noticer, Adviser (an ACT-inspired model with positive psychology elements).
• Core idea: help young people flexibly switch among Discoverer (exploration), Noticer (awareness), and Adviser (values-guided action) to respond adaptively to context and maintain vitality.
• Practical concepts:
  • Inside/Outside vision: internal thoughts/feelings vs. external behavior and presentation
  • Power grids (two-by-two): balance expression of internal states with social actions
  • Values work: identify what matters in life and how to act in ways aligned with values
• Evidence base: growing body of evidence supporting DNAV for children and adolescents; resources and worksheets available (e.g., values, inside/outside visualization, etc.).
• Note: DNAV combines acceptance and commitment principles with strengths-based, value-driven action.

Case examples (diagnostic reasoning practice)

• Case 1: Kevin (6-year-old) – selective speaking: only talks to immediate family; whispers to examiner; capable of speaking in other contexts (school not speaking directly to interviewer).
  • Likely diagnosis: Selective Mutism (with prominent social/communication avoidance limited to non-family settings).
• Case 2: Frank (8-year-old) – chronic worry about grades; nightly panic-like symptoms; panic attacks lasting ~15–20\text{ minutes}; family history of panic/depression; sleeps in living room; worries about college admission.
  • Diagnostic consideration: Panic Disorder with secondary generalized worry; due to recurrent panic attacks and persistent worry; may also have GAD features given ongoing worry about multiple domains (grades, future). Requires full DSM-5 criteria confirmation; consider comorbidity with family history.
• Case 3: Yoshino – onset very early with diverse fears: loud noises, strangers, separation, injuries, darkness, large animals; later fears include embarrassment, social rejection; across age spans, fears broadened to earthquakes, hurricanes; adolescence shows fear of injury and social alienation.
  • Interpretation: broadly developmental and multi-domain anxiety; may reflect multiple phobias with separation anxiety; or a pervasive/anxiety disorder spectrum requiring comprehensive assessment; not easily categorized into a single DSM-5 phobia; likely high comorbidity or generalized anxiety spectrum.
• Case 4: Tina (10) – extreme school refusal; somatic symptoms (stomachaches, headaches); mother stays with her at school; family notes Tina began worrying about leaving family after grandmother’s death; frequently requires parental support to attend school; sister often accompanies her to activities.
  • Likely diagnosis: Separation Anxiety Disorder with school refusal, given fear of leaving family and functional impairment in school attendance.
• Case 5: Emily (7) – extreme withdrawal from peers at recess; prefers family interaction; afraid of embarrassment; no friends at school or neighborhood; socially engaged at home.
  • Likely diagnosis: Social Anxiety Disorder with social withdrawal; potential selective peer avoidance; differentiate from autism by context and cross-setting social functioning (home vs. school).
• Case 6: Nina (8) – sad, quiet, nocturnal fears; nightmares about father molesting her; father in jail; fear of jail; conflicts with mother; aggressive/disruptive at school; sleep problems; home stressors.
  • Likely diagnosis: PTSD with current distress related to trauma exposure (father’s abuse and father’s incarceration) and ongoing night-time symptoms; assess for traumatic exposure and related symptoms (re-experiencing, avoidance, negative alterations in cognition/mood, hyperarousal).

Practical tools and activities for assessment and intervention (child-friendly)

• Track My Fears worksheet: identifies cognitive, emotional, interpersonal, physiological, and behavioral components of fear; forms basis for intervention planning.
• Fear thermometer: scale 0–10 to quantify fear in situ; informs exposure hierarchy and progress tracking.
• Body maps: illustrate where anxiety is felt in the body; fosters somatic awareness and helps tailor coping strategies.
• Thoughts in bubbles: capture anxious thoughts; links between cognition, affect, and behavior.
• Exposure ladders and red-yellow-green stoplight: structure exposure tasks by difficulty and tolerance; guide progression.
• Storybooks for psychoeducation (e.g., Ruby Finds a Worry, Tom Percival): child-friendly narratives to explain worries and coping strategies; useful for parents and clinicians.
• Functional Behavioral Assessments (FBA): use ABC data, indirect/direct assessment, and school/home observations to identify function of avoidance or anxiety-related behaviors; informs targeted interventions and collaboration with schools.

Cultural considerations

• Fear content can vary by country and culture (e.g., Chinese children reporting fear of social evaluative situations; Caribbean children more likely to fear nature; lower-SES children fearing rats, cockroaches, etc.).
• When assessing or treating, consider family beliefs about anxiety, willingness to engage in therapy, and language or access barriers.
• Tailor interventions to fit family values, norms, and available resources; ensure culturally responsive practice.

Summary and conclusions

• Anxiety in children stems from a biopsychosocial mix of predispositions, precipitating events, and maintaining factors; developmentally appropriate fears can become disorders when impairment is significant or persistent.
• Assessment relies on multiple sources (clinical interview, standardized measures, parent/teacher reports, and functional assessment) and includes monitoring tools to track progress.
• Interventions are most effective when tailored to the child and family, with CBT as a central approach, complemented by ACT/DNAV-based strategies and family/school involvement.
• A modular, flexible approach (CBT modules, exposure, relaxation, skills training) often yields the best outcomes; DNAV provides an ACT-like, values-driven framework incorporating Discoverer, Noticer, and Adviser roles.
• Case vignettes illustrate diverse presentations (selective mutism, panic/GAD features, multi-domain anxiety, separation anxiety with school refusal, social anxiety, trauma-related distress) and highlight the need for careful formulation and individualized intervention.
