Validation of the Patient Health Questionnaire-9 for Depression Screening Among Chinese Americans

OBJECTIVE The objective of this study was to validate the Chinese Bilingual version of the Patient Health Questionnaire (CB-PHQ-9) for screening for depression among Chinese Americans in primary care. METHOD Chinese-American patients attending a primary care clinic were screened for major depressive disorder (MDD) using the CB-PHQ-9. All patients who scored 15 or higher on the CB-PHQ-9 were interviewed using the Chinese-bilingual Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, patient version. Eight percent of patients who scored less than 15 on the CB-PHQ-9 were randomly selected and interviewed with the depression module of the Chinese-bilingual Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, patient version. RESULTS During the study, 1940 unduplicated patients completed the CB-PHQ-9. The CB-PHQ-9 had high internal consistency (alpha = 0.91), and the scores of each of its 9 items had moderate to moderately high correlations (0.52-0.85) with the total scores. The sensitivity and specificity of the CB-PHQ-9 for recognizing MDD were found to be 81% and 98%, respectively, and the area under the receiver operating characteristic curve was estimated to be 0.97 (SE, 0.01). CONCLUSION The CB-PHQ-9 is a valid and useful instrument for screening for MDD among Chinese Americans in primary care.

Empirical testing of two models for staging antidepressant treatment resistance.

Background: An increasing amount of attention has been paid to treatment resistant depression. Although it is quite common to observe nonremission to not just one but consecutive antidepressant treatments during a major depressive episode, a relationship between the likelihood of achieving remission and ones degree of resistance is not clearly known at this time. This study was undertaken to empirically test 2 recent models for staging treatment resistance. Materials and Methods: Psychiatrists from 2 academic sites reviewed charts of patients on their caseloads. Clinical Global Impressions-Severity (CGI-S) and Clinical Global Impressions-Improvement (CGI-I) scales were used to measure severity of depression and response to treatment, and 2 treatment-resistant staging scores were classified for each patient using the Massachusetts General Hospital staging method (MGH-S) and the Thase and Rush staging method (TR-S). Results: Out of the 115 patient records reviewed, 58 (49.6%) patients remitted at some point during treatment. There was a significant positive correlation between the 2 staging scores, and logistic regression results indicated that greater MGH-S scores, but not TR-S scores, predicted nonremission. Conclusions: This study suggests that the hierarchical manner in which the field has typically gauged levels of treatment resistance may not be strongly supported by empirical evidence. This study suggests that the MGH staging model may offer some advantages over the staging method by Thase and Rush, as it generates a continuous score that considers both number of trials and intensity/optimization of each trial.

Rating Scales for Depression

Over the past few decades, a number of clinician-rated and patient-rated instruments have been developed as primary efficacy measures in depression clinical trials. All those scales have relative strengths and weaknesses and some of them have been more successful than others, and have become the gold standards for depression clinical research. With all these measures available and with the evidence of their variable performance in clinical trials, it is becoming increasingly important to select primary efficacy measures that are reliable, valid, and that fit well within the aims of depression clinical trials. This article will review the main considerations that investigators need to make when choosing a primary efficacy measure for major depressive disorder (MDD). There is a clear need for a thorough discussion of the methodological issues concerning the use of these scales, as suggested also by Demyttenaere and De Fruyt in a recent review [1], because clinical trials researchers in depression continue to struggle with the ability to detect signals of the efficacy of antidepressant agents.

Illness beliefs of depressed Chinese American patients in primary care

This study investigated the illness beliefs of 40 depressed Chinese Americans in a primary care setting using the Exploratory Model Interview Catalogue (EMIC). Twenty-two depressed Chinese Americans (76%) complained of somatic symptoms; 4 (14%) reported psychological symptoms including irritability, rumination, and poor memory. No patients reported depressed mood spontaneously. Yet, 93% endorsed depressed mood when they filled out the CBDI. Twenty-one patients (72%) did not know the name of their illness or did not consider it a diagnosable medical illness, and five patients (17%) attributed their symptoms to pre-existing medical problems. Only three patients (10%) labeled their illness as psychiatric conditions. The patients generally sought help from general hospital (69%), lay help (62%), and alternative treatment (55%) but rarely from mental health professionals (3.5%) for their depressive symptoms. The results suggest that many Chinese Americans do not consider depressed mood a symptom to report to their physicians, and many are unfamiliar with depression as a treatable psychiatric disorder.

Use of the Chinese version of the Beck Depression Inventory for screening depression in primary care.

Many Asian-Americans are unfamiliar with depression and its treatment. When depressed, they generally seek treatment from their primary care physicians and complain about their physical symptoms, resulting in under-recognition and under-treatment of depression. This study evaluates the effectiveness of the Chinese version of the Beck Depression Inventory (CBDI) for screening depression among Chinese-Americans in primary care. A total of 503 Chinese-Americans in the primary care clinic of a community health center were administered the CBDI for depression screening. Patients who screened positive (CBDI ≥ 16) were interviewed by a psychiatrist using the Structured Clinical Interview for DSM-III-R, patient version (SCID-I/P) for confirmation of the diagnosis. Patients who screened negative (CBDI < 16) were randomly selected to be interviewed using the depression module of the SCID-I/P. The results of the SCID-I/P interview were used as the standard for evaluating the sensitivity and specificity of the CBDI. A total of 815 Chinese-Americans in a primary care clinic were approached, and 503 completed the CBDI. Seventy-six (15%) screened positive (CBDI ≥ 16), and the prevalence of major depression was 19.6% by using extrapolated results from SCID-I/P interviews. When administered by a native-speaking research assistant, the CBDI has good sensitivity (.79), specificity (.91), positive predictive value (.79), and negative predictive value (.91). Despite the commonly believed tendency to focus on physical symptoms rather than depressed mood, Chinese-Americans are able to report symptoms of depression in response to a questionnaire. The CBDI, when administered by research assistants, has good sensitivity and specificity in recognizing major depression in this population. Lack of interest among Chinese-American patients in using the CBDI as a self-rating instrument has limited its use for depression screening in primary care settings.

Meta-analysis of randomized controlled trials of cranial electrostimulation : efficacy in treating selected psychological and physiological conditions

To clarify the diverse published results of cranial electrostimulation (CES) efficacy, we conducted an extensive literature review that identified 18 of the most carefully conducted randomized controlled trials of CES versus sham treatment. For the 14 trials that had sufficient data, we used the techniques of meta-analysis to pool the published results of treating each of four conditions: anxiety (eight trials), brain dysfunction (two trials), headache (two trials), and insomnia (two trials). Because studies utilized different outcome measures, we used an effect size method to normalize measures which we then pooled across studies within each condition. The meta-analysis of anxiety showed CES to be significantly more effective than sham treatment (p < .05). Pooling did not affect results that were individually positive (headache and pain under anesthesia) or negative (brain dysfunction and insomnia). Most studies failed to report all data necessary for meta-analysis. Moreover, in all but two trials, the therapist was not blinded and knew which patients were receiving CES or sham treatment. We strongly recommend that future trials of CES report complete data and incorporate therapist blinding to avoid possible bias.

Culturally sensitive collaborative treatment for depressed Chinese Americans in primary care.

OBJECTIVES We examined the feasibility and effectiveness of using culturally sensitive collaborative treatment (CSCT) to improve recognition, engagement, and treatment of depressed Chinese Americans in primary care. METHODS Chinese American patients in a primary care setting (n = 4228) were screened for depression. The primary study outcome was treatment engagement rate, and the secondary outcome was treatment response. RESULTS Of the study participants, 296 (7%) screened positive for depression, 122 (41%) of whom presented for a psychiatric assessment; 104 (85%) were confirmed with major depressive disorder, and 100 (96%) of these patients were randomized into treatment involving either care management or usual care. Patients in the care management and usual care groups did not differ in terms of their outcomes. CSCT resulted in a nearly 7-fold increase in treatment rate among depressed patients in primary care. CONCLUSIONS CSCT is both feasible and effective in improving recognition and treatment engagement of depressed Chinese Americans. Care management may have limited effects on depressed patients treated by psychiatrists, given that these patients tend to have favorable responses in general.

Acupuncture for Depression: A Review of Clinical Applications

While increasing numbers of patients are seeking acupuncture treatment for depression in recent years, there is limited evidence of the antidepressant (AD) effectiveness of acupuncture. Given the unsatisfactory response rates of many Food and Drug Administration- approved ADs, research on acupuncture remains of potential value. Therefore, we sought to review the efficacy and safety of acupuncture treatment for depression in clinical applications. We conducted a PubMed search for publications through 2011. We assessed the adequacy of each report and abstracted information on reported effectiveness or efficacy of acupuncture as monotherapy for major depressive disorder (MDD) and as augmentation of ADs. We also examined adverse events associated with acupuncture, and evidence for acupuncture as a means of reducing side effects of ADs. Published data suggest that acupuncture, including manual-, electrical-, and laser-based, is a generally beneficial, well-tolerated, and safe monotherapy for depression. However, acupuncture augmentation in AD partial responders and nonresponders is not as well studied as monotherapy; and available studies have only investigated MDD, but not other depressive spectrum disorders. Manual acupuncture reduced side effects of ADs in MDD. We found no data on depressive recurrence rates after recovery with acupuncture treatment. Acupuncture is a potential effective monotherapy for depression, and a safe, well-tolerated augmentation in AD partial responders and nonresponders. However, the body of evidence based on well-designed studies is limited, and further investigation is called for.

The relationship between DSM-III personality disorders and the five-factor model of personality

Two hundred twenty-four first-degree relatives of patients with psychotic disorders were administered the Structured Interview for DSM-III Personality Disorders (SIDP) and completed a self-report instrument to assess dimensions of the five-factor model of personality. All of the DSM-III personality disorders were related to one or more dimensions of the five personality factors; however, the correlations were generally low. It seems that the five personality factors describe important features of DSM-III personality disorders, but are not sufficient to completely explain their characteristics. Future use of the five-factor model in conjunction with personality disorder diagnoses may provide useful information for clinical work and research purposes.

College Students: Mental Health Problems and Treatment Considerations.

Attending college can be a stressful time for many students. In addition to coping with academic pressure, some students have to deal with the stressful tasks of separation and individuation from their family of origin while some may have to attend to numerous work and family responsibilities. In this context, many college students experience the first onset of mental health and substance use problems or an exacerbation of their symptoms. Given the uniqueness of college students, there is a need to outline critical issues to consider when working with this population. In this commentary, first, the prevalence of psychiatric and substance use problems in college students and the significance of assessing age of onset of current psychopathology are described. Then, the concerning persistent nature of mental health problems among college students and its implications are summarized. Finally, important aspects of treatment to consider when treating college students with mental health problems are outlined, such as the importance of including parents in the treatment, communicating with other providers, and employing of technology to increase adherence. It is concluded that, by becoming familiar with the unique problems characteristic of the developmental stage and environment college students are in, practitioners will be able to better serve them.
