Cognitive Behavioral Therapy for a Young Woman of Asian Heritage: A Comprehensive Case Study for Generalized Anxiety Disorder

Theoretical and Research Basis for Generalized Anxiety Disorder (GAD)

Definition and Prevalence of GAD: * Generalized anxiety disorder (GAD) is identified as one of the most common anxiety disorders among adults in the general population. * According to the American Psychiatric Association ( $2013$ ), approximately $9$ million adults meet the criteria for GAD within any $12$ -month period. * Individuals have a $9\%$ chance of meeting GAD criteria during their lifetime.
Economic Impact: * The average $3$ -month economic cost for an adult living with GAD is approximately $\$733$ ( $\$849$ when adjusted for inflation). * This cost calculation includes the direct expense of treatment and indirect costs such as lost wages.
Diagnostic Criteria (DSM-5): * The primary criteria include frequent and excessive worry about unrelated events or activities for more days than not for at least $6$ months. * Associated symptoms include restlessness, fatigue, reduced concentration, irritability, muscle tension, and sleep disturbances. * These symptoms must significantly interfere with social, academic, or occupational functioning.
Comorbidity with Depression: * GAD is frequently comorbid with Major Depressive Disorder (MDD) or general depressive symptoms. * Research indicates that $72\%$ of lifetime anxiety cases are comorbid with depression, with the anxiety diagnosis generally preceding the depression diagnosis.

Mental Health Disparities and the Asian Heritage Population

Presenting Problems in Younger Generations: * Common issues for South Asian patients in the United States include difficulty adapting to Western culture and challenges with peer acceptance. * Conflicts often arise between balancing independence and seeking parental approval, or failing to meet parental expectations. * Somatic manifestations: Younger generations frequently present with physical symptoms such as abdominal pain, sleep problems, and headaches, which are often linked to underlying mood or anxiety disorders.
Comparative Prevalence Rates: * The $12$ -month prevalence rate for GAD in the United States is approximately $2\%$ . * In China, the $12$ -month prevalence is approximately $0.8\%$ , with a lifetime prevalence of $1.2\%$ .
Reasons for GAD Underestimation in Asian Cultures: 1. Higher stigmatization of psychiatric disorders compared to Western cultures. 2. GAD is often viewed as a transient condition rather than a treatable mental health concern. 3. Primary care physicians may lack awareness of diagnostic criteria and treatment options. 4. General lack of psychiatric services within many Asian countries.
Barriers to Treatment: * Stigma, overly involved parents, and financial challenges serve as major barriers. * There is a documented low use of mental health services and high rates of pre-intake attrition (dropping out before the first official session).

Cognitive Behavioral Therapy (CBT) and Cultural Adaptations

General Efficacy: * Meta-analyses show large treatment effects for CBT in GAD ( $\text{Hedges's } g = 0.84$ ). * For Western individuals, the average effect size is recorded at $g = -1.01$ . For adolescents and young adults, it is $g = -0.67$ . * CBT for comorbid anxiety and depression shows medium effect sizes ( $g = 0.71$ ).
CBT Core Principles: * CBT aims to identify and restructure negative beliefs about the self and others, replacing maladaptive behaviors with coping skills. * Standard interventions include psychoeducation on the relationship between thoughts, feelings, and behaviors.
Cultural Congruence and Tension: * Tensions: Collectivist approaches and emotional restraint in Asian cultures can be incompatible with standard CBT, which is rooted in European individualist values. * The Asian value of not questioning authority figures may make clients appear less active or verbal in sessions. * Similarities: Both CBT and traditional Asian values emphasize logical thinking and solution-focused approaches. Direct guidance and structured practice are often appreciated.
Huey & Tilley (2018) Framework for Adaptation: * Address cultural norms and values. * Include culturally appropriate interventions. * Adopt a direct style consistent with hierarchical relationships.

Case Introduction: "Meili"

Demographics: * Meili was a partnered, heterosexual, cisgender Chinese female in her early $20$ s living in an urban Tennessee community. * At the start of therapy, she was a senior college student; two and a half months into treatment, she transitioned to full-time employment as a Certified Nursing Assistant (CNA).
Referral and Initial Presentation: * Referred to a community-based psychology training clinic after expressing intense anxiety to a college instructor. * Symptoms emerged approximately $7$ months prior to intake. * Primary symptoms included persistent worry, ruminative/intrusive thoughts, muscle tension, headaches, avoidant behaviors, and feelings of hopelessness. * Two weeks before intake, she experienced an "emotional attack" consisting of uncontrollable crying while driving, leading to fears of "losing her mind."
Interpersonal and Occupational Impact: * Decreased productivity and engagement at school and work due to fear of performance perception. * Withdrawal from friends to avoid having an anxiety attack in their presence. * Partner complained of her being "emotionally unavailable" and noted a sharp decrease in sexual contact. * Workplace stressors included microaggressions (e.g., coworkers asking if she spoke English, liked American food, or was in the country legally).

History and Developmental Factors

Family Background: * Only child born in suburban China. Mother is a successful dentist; father was unemployed, which caused family strife. * Moved to the US at age $15$ for education as a "token of respect" for her parents, despite misgivings. * Lived with paternal aunt and uncle for $2$ years before university.
Recent Stressors: * Father moved to the US to live with her for $6$ months during her senior year. He provided unsolicited advice, criticized her work performance, and changed her turtle's diet without permission. * Meili felt treated like a child and experienced cultural conflict between her frustration and the need to "respect him."

Assessment and Diagnosis

Assessment Tools: * Semi-structured clinical interview. * DASS-21 (Depression, Anxiety, and Stress Scale-21): Measures depression, physiological arousal (anxiety), and worry/irritability (stress). * DASS-21 clinical thresholds: Depression > 9, Anxiety > 7, Stress > 14.
Preintervention Scores: * Depression: $10$ (Mild). * Anxiety: $10$ (Moderate). * Stress: $20$ (Moderate).
Diagnosis: * Generalized Anxiety Disorder (F41.1). * Acculturation Difficulty (Z60.3). * Major Depressive Disorder was not assigned as the depressive symptoms were viewed as secondary to anxiety.

Treatment Course: Mastery of Your Anxiety and Worry (MAW)

Treatment Structure: * Total of $27$ sessions over $6$ months ( $45$ -min sessions). * Base protocol: Treatments that Work: Mastery of Your Anxiety and Worry (Zinbarg, Craske, & Barlow, $2006$ ). * Modifications: Slower pacing, breaking segments into more sessions, and replacement of idioms with clear language.
Module 1: Psychoeducation and Cognitive Restructuring: * Sessions focused on the anxiety response cycle (thoughts-emotions-behaviors). * Specific discussion on the stigma of mental illness to alleviate Meili's sense of "wrongdoing." * Moved from a directive, goal-focused style toward a Socratic style.
Module 2: Relaxation and Coping Skills: * Instruction in Progressive Muscle Relaxation (PMR), breath monitoring, and nonjudgmental mindfulness. * Culturally relevant imagery: Visualizing peaceful places in her birth city in China as a grounding method.
Module 3: Imagery, Exposure, and Negative Cognitions: * Identified worrisome images (e.g., judgment from parents for not fulfilling career goals). * In vivo exposure: Meili went to lunch with coworkers and discussed Chinese culture, which left her feeling empowered.
Module 4: Safety Behavior Reduction and Maintenance: * Safety behaviors identified: Excessive phone checking, seeking frequent reassurance, and deferring to parents even when in disagreement. * Goal: Initiate social contact and limit phone checking to $4$ times per day. * Challenge: She struggled with reducing deference to parents due to the cultural value of family piety.

Complicating Factors and Barriers to Care

The Father's Visit: During week $4$ of treatment, Meili’s father moved in, causing a spike in DASS-21 scores across all scales. His presence reinforced negative self-efficacy and avoidant behaviors.
Developmental Staged: As an emerging adult ( $18\text{--}29$ ), Meili was navigating instability and identity exploration, which are associated with higher anxiety rates.
Financial Barriers: Upon graduating and becoming financially independent, Meili missed sessions due to costs. The clinic reduced her fee to maintain treatment.
Therapeutic Alliance: Alliance was built slowly; Meili was initially reluctant to disclose details, a pattern consistent with research on Chinese clients.

Clinical Outcomes and Analysis

Outcome Data (DASS-21 post-booster): * Depression: $2$ (Nonclinical). * Anxiety: $0$ (Nonclinical). * Stress: $4$ (Nonclinical).
Reliable Change Index (RCI): * Using Chinese Norms: * Depression: \text{RCI} = -5.89, p < .05. * Physiological Anxiety: \text{RCI} = -5.47, p < .05. * Stress: \text{RCI} = -6.19, p < .05. * Using Western Norms: * Depression: \text{RCI} = -2.30, p < .05. * Physiological Anxiety: \text{RCI} = -2.51, p < .05. * Stress: \text{RCI} = -3.72, p < .05.
Follow-Up: After a one-month break, a booster session confirmed she retained skill sets and reported increased self-confidence.

Recommendations for Clinicians

Community Outreach: Effort should be made to normalize mental health treatment to reduce cultural stigma.
Rapport and Cultural Safety: Establish a safe space where cultural similarities and differences can be discussed without judgment.
Therapist-Pleasing Behavior: Be aware of potential "good patient" behavior (underreporting symptoms) and use multiple assessment tools to evaluate true gains.
Language Barriers: Avoid idioms and figurative language; ensure worksheets are modified to be culturally and linguistically clear.
Social Support: Encourage clients to build social networks, as social support is linked to adjustment and self-esteem during the college-to-career transition.
