Objectives
Following this talks, participants will be able to:• Discuss barriers to mental health access for Asian
Americans • Select appropriate depression screening tools for
primary care settings• Recognizes benefits and drawbacks of using
depression screening tools
3
Mental health worldwide
• Worldwide, anxiety disorders are the most prevalent mental health disorders
• Depressive disorders are the second most prevalent group of mental disorders
• By 2020, major depression will be the most disabling disease behind cardiovascular disease

Primary care
• Prevalence major depressive disorder (MDD) in primary care settings: 5-13%
• Primary care providers deliver majority of treatment for MDD– 1/3 – ½ adult patients– 2/3 geriatric patients
• Majority patients go undiagnosed– Training, time constraints, non-specific somatic
complaints
5
Asian Americans
• 2010: 18.2 million Asian Americans in the US population
• 2050: estimated 40.6 million, 9.2% total population
• 2nd highest risk of suicide risk in females 18-24 = Asian American women
• Incidence suicide among Asian Americans grew 100% between 2000-2009
6
Barriers to access
• Lack appropriate mental health providers• Turning to religious leaders, family, peers for help• Public stigma• Language barriers (English vs non-English)• Generational– 1st, 2nd generation vs 3rd generation– Asian American college students highest rate stigma
• Self-help books, hotlines
7
Barriers to access
• Augsberger (2015): 701 Asian American female participants– Chinese > Korean > Vietnamese > mixed– Factors influencing under utilization of mental health
services• Family, community stigma– Dismissive, saving face
• Culturally appropriate treatments– Dual culture providers

Screening for depression
• US Preventative Task Force (JAMA 2016):– Recommends screening depression in the general adult
population
• Only ~half (48.6%) of adults are assessed for depression within primary care– Often not screened unless symptom complaint
• Asian Americans less likely to be screened (OR 0.35, 95% CI 0.19 – 0.67) compared to Hispanic or African American populations
9
Ideal screening tool
• Valid• Reliable• Brief• Easy to administer• Low cost/free• Effective clinical outcomes
• No single screening tool recommended over another • Selection based on setting, population
10
Screening tools for depression
• Beck Depression Inventory (BDI)• Zung Self-Assessment Depression Scale (ZSDS)• General Health Questionnaire (GHQ)• Patient Health Questionnaire 9 (PHQ-9)• Patient Health Questionnaire 2 (PHQ-2)• Center for Epidemiologic Study Depression Scale
(CES-D)• Geriatric Depression Scale (GDS)
11
Center for Epidemiologic Study Depression Scale (CES-D)
• 20-item questionnaire• Most commonly used in studies with Asian
Americans (versus clinic populations?)• Accounts for somatic symptoms more commonly
found in Asian American patients– Changes in appetite, headache, stomach aches, insomnia,
fatigue• Can also be used in adolescents

13
Geriatric Depression Scale (GDS)
• 15-item and 30-item versions• 15-item GDS sensitivity (82-100%) (72-87%)• Recommended for easy yes/no format
14
Geriatric Depression Scale (GDS)
15
PHQ-2
• 2-item questions asks about depressed mood and anhedonia
• May be administered verbally, takes < 2 minutes to administer
• Validated, may be as effective as more extensive instruments
• Can be used as a first step screener
16

5
PHQ-9
• Cut-off score varies between countries, settings (primary care, community care, non-primary care)
• Sometimes considered the “gold standard” for depression screening
• Cut-off score >10, less sensitive but more specific (74%, 86%)
17
PHQ-9
18
PHQ-9: will it work for Asian populations?
• Reliability and validity confirmed in Asian populations– Korean, including geriatric– Chinese, including adolescents– Thai– Indian adolescents– English speaking Singaporean residents
• Available in Mandarin, Hindi, Punjabi, Gujarti, Japanese, Korean, Thai

Screening tool drawbacks
• Not diagnostic!• Higher scores do not necessarily correlate with
severity• Short item questionnaires (2-3 items) have high false
positive rates• Varying degrees of sensitivity, specificities among
screening tools• Varying cut-off values• Confounding co-morbid disease• Must have adequate treatment and follow-up
21
Summary
• Depression is a major cause of morbidity worldwide• Asian American populations are less likely to be
screened than other populations• Ideal screening tools should be cost-effective, easy
to administer, accurate• Variety of screening tools available; no evidence that
one is more effective than others• Screening should be followed with interview and
appropriate treatment, follow up
