Validity of the Spanish-Language Patient Health Questionnaires 2 and 9: A Systematic Review and Meta-Analysis.

Importance: Reliable screening for major depressive disorder (MDD) relies on valid and accurate screening tools. Objective: To examine the validity, accuracy, and reliability of the Spanish-language Patient Health Questionnaires 2 and 9 (PHQ-2 and PHQ-9) to screen for MDD. Data Sources: PubMed, Web of Science, Embase, and PsycINFO from data initiation through February 27, 2023. Study Selection: English- and Spanish-language studies evaluating the validity of the Spanish-language PHQ-2 or PHQ-9 in screening adults for MDD compared with a standardized clinical interview (gold standard). Search terms included PHQ-2, PHQ-9, depression, and Spanish. Data Extraction and Synthesis: Two reviewers performed abstract and full-text reviews, data extraction, and quality assessment. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Random-effects meta-analyses of sensitivity, specificity, and area under the curve (AUC) were performed. Internal consistency was evaluated using Cronbach α and McDonald ψ. Main Outcomes and Measures: Test accuracy and internal consistency. The PHQ-2 is composed of the first 2 questions of the PHQ-9 (targeting core depression symptoms of depressed mood and anhedonia; a score of 3 or higher (score range, 0-6) is generally considered a positive depression screen. If a patient screens positive with the PHQ-2, a follow-up assessment with the PHQ-9 and a clinical diagnostic evaluation are recommended. Once depression is diagnosed, a PHQ-9 score of 10 or higher (score range, 0-27) is often considered an acceptable threshold for treating depression. Results: Ten cross-sectional studies involving 5164 Spanish-speaking adults (mean age range, 34.1-71.8 years) were included; most studies (n = 8) were in primary care settings. One study evaluated the PHQ-2, 7 evaluated the PHQ-9, and 2 evaluated both the PHQ-2 and PHQ-9. For the PHQ-2, optimal cutoff scores ranged from greater than or equal to 1 to greater than or equal to 2, with an overall pooled sensitivity of 0.89 (95% CI, 0.81-0.95), overall pooled specificity of 0.89 (95% CI, 0.81-0.95), and overall pooled AUC of 0.87 (95% CI, 0.83-0.90); Cronbach α was 0.71 to 0.75, and McDonald ψ was 0.71. For the PHQ-9, optimal cutoff scores ranged from greater than or equal to 5 to greater than or equal to 12, with an overall pooled sensitivity of 0.86 (95% CI, 0.82-0.90), overall pooled specificity of 0.80 (95% CI, 0.75-0.85), and overall pooled AUC of 0.88 (95% CI, 0.87-0.90); Cronbach α was 0.78 to 0.90, and McDonald ψ was 0.79 to 0.90. Four studies were considered to have low risk of bias; 6 studies had indeterminate risk of bias due to a lack of blinding information. Conclusions and Relevance: In this systematic review and meta-analysis, limited available evidence supported the use of the Spanish-language PHQ-2 and PHQ-9 in screening for MDD, but optimal cutoff scores varied greatly across studies, and few studies reported on blinding schemes. These results suggest that MDD should be considered in Spanish-speaking individuals with lower test scores. Given the widespread clinical use of the tools and the heterogeneity of existing evidence, further investigation is needed.

Antiracism in Action: Development and Outcomes of a Mentorship Program for Premedical Students Who Are Underrepresented or Historically Excluded in Medicine.

INTRODUCTION: Black, Latinx, and Native American and Alaska Native people are underrepresented in medicine. The increasingly competitive medical school application process poses challenges for students who are underrepresented in medicine or historically excluded from medicine (UIM/HEM). The University of California, San Francisco-University of California, Berkeley (UCSF-UCB) White Coats for Black Lives Mentorship Program provides a novel and antiracist approach to mentorship for these premedical students. METHODS: The program recruited UIM/HEM premedical and medical students through a survey advertised by email, on the program's website, social media, and by word of mouth. The program paired students primarily with race-concordant mentors, all of whom were UCSF medical students. From October 2020 to June 2021, program mentees engaged in skills-building seminars based on an antiracism framework and received support for preparing medical school applications. The program administered preprogram and postprogram surveys to mentees, which were analyzed via quantitative and qualitative methods. RESULTS: Sixty-five premedical mentees and 56 medical student mentors participated in the program. The preprogram survey received 60 responses (92.3% response rate), and the postprogram survey received 48 responses (73.8% response rate). In the preprogram survey, 85.0% of mentees indicated that MCAT scores served as a barrier "a great deal" or "a lot," 80.0% indicated lack of faculty mentorship, and 76.7% indicated financial considerations. Factors that improved most from preprogram to postprogram were personal statement writing (33.8 percentage-point improvement, P < .001), peer mentorship (24.2 percentage-point improvement, P = .01), and knowledge of medical school application timeline (23.3% percentage-point improvement, P = .01). CONCLUSION: The mentorship program improved student confidence in various factors influencing the preparation of medical school applications and offered access to skills-building resources that mitigated existing structural barriers.

Validity of the Chinese Language Patient Health Questionnaire 2 and 9: A Systematic Review.

Introduction: Chinese Americans with limited English proficiency have higher mental health needs than English speakers but are more likely to be undiagnosed and undertreated for depression. Increasing anti-Asian hate crimes during the COVID-19 pandemic has increased the urgency to accurately detect depressive symptoms in this community. This systematic review examines the validity of the Patient Health Questionnaire (PHQ)-2/9 for depression screening in Chinese-speaking populations. Methods: We queried PubMed, Web of Science, Embase, and PsycINFO databases, examining studies through September 2021. Studies were included if they evaluated the Chinese language PHQ-2 or PHQ-9 and diagnosed depression using a clinical interview. Two investigators independently extracted study data and assessed quality using the QUADAS-2. Study sensitivities and specificities were combined in random effects meta-analyses. Results: Of 513 articles, 20 met inclusion criteria. All examined the PHQ-9; seven also examined the PHQ-2. Studies were conducted in Mainland China (17), Hong Kong (1), Taiwan (1), and the United States (1). Fourteen studies were published in English; six in Chinese. Studies were diverse in setting, participant age, and comorbidities. For the Chinese language PHQ-9, Cronbach's alpha ranged from 0.765 to 0.938 for included studies (optimal cutoff scores ranged from 6 to 11). For the PHQ-2, Cronbach's alpha ranged from 0.727 to 0.785 (optimal cutoff scores 1-3). Overall, the PHQ-9 pooled sensitivity was 0.88 (95% CI 0.86-0.90), and pooled specificity was 0.87 (95% CI 0.83-0.91). Similarly, the pooled PHQ-2 sensitivity was 0.84 (95% CI 0.80-0.87), and pooled specificity was 0.87 (95% CI 0.78-0.93). The overall risk of bias was low (12 studies) or indeterminate (8 studies). Discussion: While limited by missing study information, the Chinese language PHQ-9 appears to be a valid depression screening tool among Chinese-speaking populations across geographic and clinical settings. Further research should explore optimal cutoff scores for this population for routine depression screening and the validity of the tool to measure response to depression treatment.

Disparities in peripheral artery disease care: A review and call for action.

Peripheral artery disease (PAD), the pathophysiologic narrowing of arterial blood vessels of the lower leg due to atherosclerosis, is a highly prevalent disease that affects more than 6 million individuals 40 years and older in the United States, with sharp increases in prevalence with age. Morbidity and mortality rates in patients with PAD range from 30% to 70% during the 5- to 15-year period after diagnosis and PAD is associated with poor health outcomes and reduced functionality and quality of life. Despite advances in medical, endovascular, and open surgical techniques, there is striking variation in care among population subgroups defined by sex, race and ethnicity, and socioeconomic status, with concomitant differences in preoperative medication optimization, amputation risk, and overall health outcomes. We reviewed studies from 1995 to 2021 to provide a comprehensive analysis of the current impact of disparities on the treatment and management of PAD and offer action items that require strategic partnership with primary care providers, researchers, patients, and their communities. With new technologies and collaborative approaches, optimal management across all population subgroups is possible.
