Detecting depression in medically ill patients: Comparative accuracy of four screening questionnaires and physicians' diagnoses in Spanish population

Impact of Anxiety and Depression on the Level of Asthma Control Among Jordanian Adults with Asthma

Purpose

Recent studies imply that psychological factors may actively contribute to the development of asthma. It is generally known that people with asthma frequently suffer from psychological illnesses. This association can make it challenging to reach asthma control. This study aimed to assess the prevalence of depression and anxiety among Jordanian adults with asthma, in addition to the link between asthma control levels and these psychological disorders.

Patients and Methods

This cross-sectional study included 175 adults with asthma who visited the tertiary asthma clinic in three Jordanian Governmental hospitals. Sociodemographic data was collected directly from the patients who were assessed for their level of depression and anxiety using a self-administered questionnaire, the Hospital Anxiety and Depression Scale (HADS). Also, asthma control was assessed using the Asthma Control Test (ACT). The relation between the different sociodemographic variables and clinical data, particularly depression and anxiety and asthma control level, was assessed.

Results

Among 175 asthmatic patients, 60.57% had poor disease control, 8% had anxiety alone, 11.43% had depression alone, and 53.14% had anxiety plus depression. Poor asthma control was significantly associated with anxiety and depression (p= 0.044) and low levels of education (p=0.001). Further, a lower level of education was also related to higher levels of anxiety and depression.

Conclusion

Most of the assessed Jordanian patients with asthma had their disease poorly controlled. Anxiety and depression are common among the studied sample of adults with asthma, and they appear to affect the level of disease control, suggesting the possibility that addressing these psychological conditions could enhance asthma control levels.

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.

The Interplay Between Use of Biological Therapies, Psychological State, and the Microbiome in IBD

Background

This study examines longitudinal bio-psychological dynamics and their interplay in IBD patients undergoing conventional and biological therapies.

Methods

Fifty IBD participants (24 UC, 26 CD) in clinical remission were followed for 12 months. Complete longitudinal datasets, biological samples, validated scores of psychological status were collected monthly for analysis of association. Microbiome analysis was performed to identify microbial dynamics and signatures. Patients were grouped on disease phenotype (CD, UC) and mode of treatment (biological therapies, non-biological treatment). General linear models, mixed models, cluster analysis, and analyses of variance were used to examine the longitudinal trends of the variables and their associations over time. Results were corrected for multiple testing.

Results

Results substantiated different interactions between biological therapy and longitudinal trends of inflammatory biomarkers in remission CD and UC patients as well as significant differences between CD and UC patients in their psychological measures during clinical remission, with UC patients having inferior condition compared to CD. A significant reduction in microbial diversity in CD patients compared to UC was identified. Results characterized considerable differences in longitudinal microbial profile between those taking and not taking biological treatment in UC patients, but not in CD patients.

Conclusion

A different trajectory of interdependence was identified between psychological state, sleep, and microbial dynamics with mode of treatment when compared between CD and UC patients. Further studies should investigate the causal relationships between bio-psychological factors for improved treatment purposes.

Pain is associated with reduced quality of life and functional status in patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Background and aims Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is challenging to live with, often accompanied by pervasive fatigue and pain, accompanied by decreased quality of life (QoL) as well as anxiety and/or depression. Associations between higher pain, lower QoL and higher anxiety and depression have been shown in patients with various chronic pain disorders. Few studies have however examined such associations in a sample of patients with ME/CFS. The aims of the current study were to examine the impact of pain levels and compare levels of pain, health related QoL, anxiety and depression between patients with ME/CFS and healthy controls. In addition, the study aimed and to examine these relationships within the patient group only. Methods This is a cross-sectional questionnaire based study comparing 87 well-diagnosed patients with ME/CFS with 94 healthy controls. The De Paul Symptom Questionnaire (DSQ), the Medical Outcomes Study Short-Form Surveys (SF-36) and the Hospital Anxiety and Depression Scale (HADS) were used to examine and compare pain, physical function, QoL, anxiety and depression in patients and healthy controls. Further the pain variables were divided into pain total, pain intensity and a pain frequency score for analyses of the above mentioned variables within the patient group only. Results Significantly higher levels of pain, anxiety and depression, and lower levels of QoL were found in the patient group compared with healthy controls. For the patient group alone, pain was significantly associated with lower QoL in terms of physical functioning, bodily pain, general health functioning, vitality and social functioning capacity. In this patient sample, only frequency of joint pain showed significant difference in psychological variables such as depression and anxiety - depression combined. Conclusions ME/CFS patients differ significantly from healthy controls in pain, health related QoL, anxiety and depression. Pain is significantly associated with reduced QoL and overall a lower level of functioning. The relation between pain and anxiety and depression appears less clear. Implications Pain is for many ME/CFS patients associated with reduced physical functioning and reduced QoL. A thorough pain assessment can therefore be essential for clinicians, and subsequent medical pain treatment combined with good pain coping skills may increase functioning level and QoL for these patients. The link between joint pain and psychological factors should also be focused in clinical practice in terms of mapping and counseling. Pain should be further examined to understand the importance it may have for functioning level as reduced function is a main criteria when diagnosing the patients.

The effect of literacy and culture on cognitive effort test performance: An examination of the Test of Memory Malingering in Colombia

Introduction: Cognitive efforts tests, such as the Test of Memory Malingering (TOMM), are widely used internationally, yet emerging research suggests that performance on the TOMM can be affected by culture and education. This study examined the specificity of the TOMM and performance differences among Colombian adults, contrasting those with varying levels of literacy in order to evaluate the impact of these variables on error rates. It was hypothesized that literacy would be positively correlated with TOMM scores. Method: The sample consisted of 256 participants: the Absolute Illiterate participants had no formal education and no ability to read or write (n = 58), Functional Illiterate participants had no formal education and only basic reading and writing skills (n = 66), Literate participants had up to 12-years of education (n = 66), and Highly Literate participants had some post-secondary education (n = 66). Group differences for Trial 1 (T1) and Trial 2 (T2) were analyzed using ANOVAs and chi-square tests, along with post-hoc comparisons. Results: Mean T2 scores for the four groups were all above the suggested cutoff score of 45: the Highly Literate group had the highest mean score (49.3, range 41 to 50), and the Absolute Illiterate group had the lowest mean score (45.5, range 30 to 50). The Absolute and Functional Illiterate groups performed significantly worse on the TOMM trials than the literate participants. Cognitive performance as measured by indicators of verbal fluency and executive control significantly correlated with TOMM performance. However, when evaluated together in hierarchical logistic regressions, only age and literacy significantly predicted TOMM scores. Conclusions: Although the performance of Colombian adults suggests that the TOMM can be used cross-culturally with literate individuals, Colombian adults with poorer literacy skills performed significantly worse, raising concerns regarding the use of this measure with educationally-diverse samples. Research and clinical implications are discussed.

Diagnostic accuracy and treatment approach to depression in primary care: predictive factors

OBJECTIVE

The study assessed the predictive factors of diagnostic accuracy and treatment approach (antidepressants versus active monitoring) for depression in primary care.

METHODS

This is a cross-sectional study that uses information from a naturalistic prospective controlled trial performed in Barcelona (Spain) enrolling newly diagnosed patients with mild to moderate depression by GPs. Treatment approach was based on clinical judgement. Diagnosis was later assessed according to DSM-IV criteria using Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) interview by an external researcher. Patients (sociodemographic, psychiatric diagnosis, severity of depression and anxiety, health-related quality of life, disability, beliefs about medication and illness and comorbidities) and GP factors associated with diagnostic accuracy and treatment approach were assessed using multilevel logistic regression. Variables with missing data were imputed through multiple imputations.

RESULTS

Two hundred sixty-three patients were recruited by 53 GPs. Mean age was 51 years (SD = 15). Thirty percent met DSM-IV criteria for major depression. Mean depression symptomatology was moderate-severe. Using multivariate analyses, patients' beliefs about medicines were the only variable associated with the antidepressant approach. Specialization in general medicine and being a resident tutor were associated with a more accurate diagnosis.

CONCLUSIONS

Clinical depression diagnosis by GPs was not always associated with a formal diagnosis through a SCID-I. GPs' training background was central to an adequate depression diagnosis. Patients' beliefs in medication were the only factor associated with treatment approach. More resources should be allocated to improving the diagnosis of depression.

Depression in systemic lupus erythematosus: gender differences in the performance of the Beck Depression Inventory (BDI), Center for Epidemiologic Studies Depression Scale (CES-D), and Hospital Anxiety and Depression Scale (HADS)

The prevalence of depressive symptoms in patients with systemic lupus erythematosus (SLE) varies widely between different cohorts (17-75%), primarily due to factors such as the heterogeneity of the samples and the instruments used to detect depressive symptoms. Most of these instruments are self-administered questionnaires that have different characteristics and approaches to depressive symptoms. This study aimed to evaluate gender differences in the performance of three questionnaires used to assess depressive symptoms in patients with SLE: the Beck Depression Inventory (BDI), Center for Epidemiologic Studies Depression Scale (CES-D), and Hospital Anxiety and Depression Scale (HADS). This study included 54 male and 54 female SLE patients. Depressive symptoms were assessed using BDI (cutoffs 13 and 15), CES-D and HADS. The gold standard method used was the diagnostic criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Regarding the performance of the BDI questionnaire, no significant differences in sensitivity or specificity were found between the genders. The specificity of the CES-D questionnaire was significantly greater for the male group (83% vs. 62.5%, p = 0.0309), and its sensitivity was non-significantly higher for the female group (92.9% for women and 71.4% for men; p = 0.2474). Regarding the performance of the HADS, we found similar sensitivities between the genders (71.4%) but a higher specificity among the men (95.7% in men and 82.5% in women, p = 0.0741). In conclusion, our results suggest the presence of gender differences in the performance of the questionnaires in SLE patients. The BDI had the most similar performances between the male and female groups. In contrast, the CES-D and HADS-D showed considerable variation in performances between men and women with SLE.

Adaptation of the BDI-II in Mexico

The number of Spanish-speaking individuals and immigrants in the United States has risen dramatically and is projected to continue to rise. The availability of appropriately translated and validated measurement instruments, such as the Beck Depression Inventory, is a priority for researchers and clinicians in the U.S. and Mexico, where the first edition of the BDI is still prominently used. The purpose of this study was to pilot a Mexican adaptation of the BDI-II and report initial psychometric characteristics. Two samples were used: students from across Mexico and community adults from Mexico City. Results indicated that the translation was easily understood by most individuals, had adequate internal consistency, and a three-factor structure (negative attitude, performance difficulties, and somatic elements) had the best fit. Implications for use with Mexican-origin Spanish speakers are discussed.

Which instruments to support diagnosis of depression have sufficient accuracy? A systematic review

BACKGROUND

Instruments are frequently used in case finding, diagnosis and severity grading of major depression, but the evidence supporting their utility is weak.

AIM

To systematically review the specificity and sensitivity of instruments used to diagnose and grade the severity of depression.

METHODS

MEDLINE, PsycInfo, Embase and the Cochrane Library databases were searched until April 2014. Fifty studies fulfilled the inclusion criteria. Risk of bias was assessed with QUADAS. The average sensitivity and specificity of each instrument was estimated with hierarchical summary receiver operating characteristics analyses and the confidence in the estimates was evaluated using GRADE. Minimum acceptable sensitivity/specificity, with structured interview as the reference, was 80%/80% for structured interviews and 80%/70% for case-finding instruments. The minimum acceptable standard for severity measures was a correlation of 0.7 with DSM-IV classification.

RESULTS

Twenty instruments were investigated. The average sensitivity/specificity was 85%/92% for the Structured Clinical Interview for DSM-IV-Axis-I Disorders (SCID-I), 95%/84% for the Mini International Neuropsychiatric Interview (MINI), < 70%/85% for the Primary Care Evaluation of Mental Disorders (PRIME-MD), 88%/78% for the Patient Health Questionnaire-9 (PHQ-9) with a cut-off score of 10, 69%/95% for PHQ-9 as a diagnostic algorithm and 70%/83% for the Hospital Anxiety and Depression Scale (HADS) with a cut-off score of 7. The confidence in the estimates for the other instruments was very low.

CONCLUSIONS

Only the SCID-I, MINI and PHQ-9 with a cut-off score of 10 fulfilled the minimum criteria for sensitivity and specificity. The use of the PRIME-MD and HADS is not supported by current evidence.

Validity of the Patient Health Questionnaire (PHQ)-9 and PHQ-2 in general internal medicine primary care at a Japanese rural hospital: a cross-sectional study

OBJECTIVE

Two depression screening tools, Patient Health Questionnaire (PHQ)-9 and PHQ-2, have not had their validity examined in general internal medicine settings in Japan. We examined the validity of these screening tools.

METHODS

A total of 598 outpatients of an internal medicine clinic in a rural general hospital were enrolled consecutively and stratified by PHQ-9 score. Seventy-five patients randomly selected and 29 patients whose results from the PHQ-9 were considered to be positive for depressive disorder were then interviewed with a semistructured interview, the Mini International Neuropsychiatric Interview. We calculated diagnostic accuracy of the PHQ-9 and PHQ-2 to detect major depression and that of the suicidality item of the PHQ-9 to detect suicidality using sampling weights with multiple imputations.

RESULTS

Sensitivity and specificity for depression were 0.86 and 0.85, respectively, for the PHQ-9 with cutoff points of 4/5, and 0.77 and 0.95, respectively, for the PHQ-2 with cutoff points of 2/3. Sensitivity and specificity of the suicidality item of the PHQ-9 were 0.70 and 0.97, respectively.

CONCLUSION

In internal medicine clinics in Japanese rural hospitals, the PHQ-2 with an optimal cutoff point for each setting plus the suicidality item of the PHQ-9 can be recommended to detect depression without missing suicidality.

Racial/ethnic differences in depressive symptoms among young women: the role of intimate partner violence, trauma, and posttraumatic stress disorder

PURPOSE

It is unclear why rates of depression differ by race/ethnicity among young women. This study examines whether racial/ethnic differences in depressive symptoms are reduced by intimate partner violence (IPV), traumatic events, and posttraumatic stress disorder (PTSD) symptoms among a clinical sample of low-income women.

METHODS

A cross-sectional sample of 2414 young African American, Hispanic, and white women completed a survey that included questions about depression, PTSD symptoms, IPV, and trauma. Binary logistic regression and Poisson regression determined whether reports of PTSD symptoms, IPV, and trauma among white, African American, and Hispanic women affected the differences in depression found in these groups.

RESULTS

Twenty-four percent reported a level of depressive symptoms that warranted further evaluation for major depressive disorders. White women had elevated levels of depressive symptoms and were more likely to report ≥4 symptoms. White women also reported higher rates of PTSD symptoms, IPV, and traumatic events than African American or Hispanic women. Differences in the likelihood of reporting ≥4 depressive symptoms by race/ethnicity were reduced after controlling for PTSD symptoms and trauma. PTSD symptoms attenuated the differences in the count of depressive symptoms between white and African American women. After controlling for PTSD symptoms, trauma attenuated the difference in the count of depressive symptoms between Hispanic and white women.

CONCLUSIONS

Elevated levels of trauma and PTSD symptoms among white women compared to African American or Hispanic women may play a role in observed racial/ethnic differences in depressive symptoms.

Impact of anxiety and depression on disease control and quality of life in asthma patients

INTRODUCTION

Patients with asthma also tend to have anxiety and depression. These comorbidities may affect asthma control and quality of life. The objective of this study was to assess the impact of anxiety and depression on asthma control and quality of life.

PATIENTS AND METHODS

Cross-sectional study of asthma outpatients was conducted at two hospitals in the Basque Country (northern Spain). Data collected included sociodemographic variables, asthma symptoms, treatment, number of exacerbations, level of control, quality of life, presence of psychological morbidities, and level of physical activity. Spirometry was performed in accordance with the recommendations of the Spanish Society of Pneumology and Thoracic Surgery.

RESULTS

Among 354 asthmatics, 77% had poor or partial control of their condition, 31% had anxiety alone, 2% had depression alone, and 10% had anxiety plus depression. Poor asthma control was associated with anxiety plus depression (odds ratio (OR): 3.61; 95% confidence interval (CI): 1.05-12.41) as well as with female patients (OR: 1.85; 95% CI: 1.11-3.10). Anxiety had an independent effect on reduced quality of life across all domains; anxiety plus depression had an even greater effect.

CONCLUSION

Among patients with asthma, anxiety and depression adversely affect asthma control and quality of life, raising the possibility that treating these psychological comorbidities could improve asthma control and quality of life.
