Case finding and screening clinical utility of the Patient Health Questionnaire (PHQ-9 and PHQ-2) for depression in primary care: a diagnostic meta-analysis of 40 studies

The impact of potentially morally injurious experience of betrayal on PTSD and depression following the October 7th terror attack

With about 1200 individuals murdered, the massacre of October 7th was one of the deadliest terrorist attacks in modern history. The mental health consequences of terrorist attacks have been documented. However, little is known of the impact of the potentially morally injurious experience (PMIE) of betrayal--in which individuals feel betrayed by leaders they once trusted--on levels of psychological burden in the aftermath of such an attack. In this national prospective cohort study, we examined to what extent the PMIE of betrayal exacerbates the risk for posttraumatic stress disorder (PTSD) and depression in the wake of the October 7th terrorist attack. A representative sample of 710 Israeli adults (362 female, 51.1%), Jews (557, 79.9%) and Arabs (153, 20.1%), aged 18-85 (M = 41.01, SD = 13.72) completed validated self-report questionnaires assessing PTSD, depression, and PMIE-betrayal at two timepoints: T1, in August 2023 (6-7 weeks before the attack) and T2, in November 2023 (5-6 weeks after the attack). In two hierarchical logistic regressions, we found that experience of PMIE-betrayal predicted diagnoses of both PTSD (OR 1.92, 95% CI 1.26-2.92) and depression (OR 2.03, 95% CI 1.37-3.01) at T2, beyond probable PTSD/depression at T1 and demographic and trauma-related variables. Moreover, in two repeated-measure analyses predicting PTSD/depression symptoms, we found significant interactions between PTSD/depression trajectories and PMIE-betrayal, meaning that the increase of PTSD/depression symptoms was significantly higher among participants experiencing betrayal in the context of the attack. Our study highlights the impact of PMIE of betrayal on the dramatic increase in psychopathology following the October 7th terror attack on Israel's population. Clinicians treating individuals coping with PTSD and depression should attend to their patients' possible exposure to betrayal following the attack. Moreover, national leaders and policymakers should take significant steps to repair the public's betrayal experience.

Development and psychometric evaluation of a questionnaire for the assessment of depression in primary care: a cross-sectional study

OBJECTIVES

To develop a new questionnaire for the diagnostic assessment of depression adapted to the primary care setting by combining psychiatric criteria and heuristics of general practitioners (GPs). Psychometric evaluation of the new questionnaire and first validity evidence.

DESIGN

The questionnaire was developed using cognitive interviews with think-aloud technique. Factorial validity was then examined in a cross-sectional study.

SETTING

Primary care. Five general practices in Bavaria, Germany.

PARTICIPANTS

15 GPs, 4 psychiatrists/psychotherapists and 13 patients participated in cognitive expert interviews. A primary care sample of N=277 consecutive patients participated in the cross-sectional study.

METHODS

After consultation with experts and literature research, the questionnaire contained a self-rating part for patients and an external part for GPs. Items were then iteratively optimised using cognitive interviews. Factorial validity was examined. To estimate internal consistency, Cronbach's α was calculated. Validity was assessed by correlating the new questionnaire and the Patient Health Questionnaire-9 (PHQ-9).

RESULTS

The preliminary version of the two-part 'Questionnaire for the assessment of DEpression SYmptoms in Primary Care' (DESY-PC) comprised 52 items for patients (DESY-PAT-1: questions about patient's environment; DESY-PAT-2: questions about depression-specific symptoms) and 21 items for GPs (DESY-GP). The analysis of the DESY-PAT-1 revealed a one-factor solution ('environmental factors') with Cronbach's α of 0.55. The items of the DESY-PAT-2 were assigned to three factors, 'depressive cognitions', 'suicidality' and 'symptoms of fatigue', with Cronbach's α of 0.86, 0.79 and 0.85, respectively. Factorial analysis revealed two factors for the DESY-GP: 'depression symptoms' and 'medical history/external factors'. Cronbach's α was 0.90 and 0.59, respectively. After factorial analysis, the DESY-PAT was reduced to 28 items, and the DESY-GP was reduced to 15 items. Correlations of the DESY-PC with the PHQ-9 were high and significant, indicating convergent validity.

CONCLUSIONS

The new questionnaire represents an innovative extension of depression questionnaires and could be particularly suitable for general practices.

The moderating role of belongingness in the contribution of depression to suicide ideation following the October 7, 2023, terrorist attack in Israel: A nationwide prospective study

INTRODUCTION

With >1300 civilians murdered, the terrorist attack of October 7 is one of the deadliest terrorist attacks in modern history. Previous research documented a sharp increase in depression in the aftermath of the attacks and the military conflict that followed. In this national prospective cohort study, we examined to what extent perceived belongingness (PB) moderates the association between depression and suicide ideation (SI) in the wake of the October 7th terrorist attack.

METHODS

A representative sample of 710 Israeli adults (of them, 362 females, 51.1 %), Jews (557, 79.9 %), and Arabs (153, 20.1 %), aged 18-85 (M = 41.01, SD = 13.72) completed questionnaires assessing depression, current SI, and perceived belongingness at two timepoints: T1 (in August 2023) and T2 (in November 2023).

RESULTS

Perceived belongingness at T1 predicted SI at T2 beyond demographic and trauma-related characteristics. Importantly, we found a significant interaction in which a PB at T1 moderated the link between depression and current SI at T2. Specifically, the level of depression at T2 contributed to current SI-T2 more strongly for individuals with low PB levels than for individuals with high PB levels.

DISCUSSION

Our study highlights the impact of PB on SI following the October 7th terrorist attack. Clinicians treating individuals coping with depression should attend to their patients' sense of belongingness, as low PB comprises a significant risk factor for current SI. Moreover, community and national initiatives that could increase levels of PB among the citizens may help to diminish suicide risk in the aftermath of the attack.

Impact of the 2022 Infant Formula Shortage on Self-Reported Rates of Anxiety and Depression: Evidence from the Household Pulse Survey

PURPOSE

To evaluate the impact of the 2022 infant formula shortage on self-reported anxiety and depression.

BACKGROUND

The US national infant formula shortage of 2022 originated from supply chain disruptions triggered by the COVID-19 pandemic, and the shortage was further compounded by a recall of tainted formula products.

METHODS

We used survey-weighted data from the Household Pulse Survey (HPS) to measure self-reported anxiety and depression among individuals with formula-fed infants less than 1 year of age. We evaluated the association between 2 formula disruption variables (being impacted by the infant formula shortage or having difficulty obtaining formula in the last 7 days) with 2 mental health outcomes (anxiety and depression) using multivariable logistic regressions.

RESULTS

We found increased odds of self-reported anxiety (aOR: 3.13; P < .001) and depression (aOR: 3.05; P = .005) for respondents affected by the infant formula shortage. There were no adjusted associations between having difficulty obtaining formula in the last 7 days and anxiety and depression.

CONCLUSIONS

Individuals affected by the infant formula shortage had increased odds of both anxiety and depression. Continued efforts to improve food security for low-income infants is critical for ensuring equitable nutritional and health outcomes across infant populations.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Continued efforts to reduce food insecurity for low-income infants are critically needed, as infant nutrition impacts caregiver mental health and infant health. Efforts to improve lactation support and breastfeeding initiation are needed in addition to improvements in access to formula.

Telephone coaching for the prevention of depression in farmers: Results from a pragmatic randomized controlled trial

INTRODUCTION

Farmers have a high risk for depression (MDD). Preventive measures targeting this often remotely living population might reduce depression burden. The study aimed to evaluate the effectiveness of personalized telephone coaching in reducing depressive symptom severity and preventing MDD in farmers compared to enhanced treatment as usual (TAU + ).

METHODS

In a two-armed, pragmatic randomized controlled trial (N = 314) with post-treatment at 6 months, farming entrepreneurs, collaborating family members and pensioners with elevated depressive symptoms (PHQ-9 ≥ 5) were randomized to personalized telephone coaching or TAU + . The coaching was provided by psychologists and consists on average of 13 (±7) sessions a 48 min (±15) over 6 months. The primary outcome was depressive symptom severity (QIDS-SR16).

RESULTS

Coaching participants showed a significantly greater reduction in depressive symptom severity compared to TAU + (d = 0.39). Whereas reliable symptom deterioration was significantly lower in the intervention group compared to TAU + , no significant group differences were found for reliable improvement and in depression onset. Further significant effects in favor of the intervention group were found for stress (d = 0.34), anxiety (d = 0.30), somatic symptoms (d = 0.39), burnout risk (d = 0.24-0.40) and quality of life (d = 0.28).

DISCUSSION

Limiting, we did not apply an upper cutoff score for depressive symptom severity or controlled for previous MDD episodes, leaving open whether the coaching was recurrence/relapse prevention or early treatment. Nevertheless, personalized telephone coaching can effectively improve mental health in farmers. It could play an important role in intervening at an early stage of mental health problems and reducing disease burden related to MDD.

Use of computer-assisted self-interview in detection of and referral for depression among adolescents living with HIV at an urban HIV treatment clinic in Uganda: a quasi-experimental study

BACKGROUND

Depression is common among adolescents living with HIV (ALHIV) and impacts their quality of life. However, it is not routinely detected and treated due to a lack of screening tools, coupled with large numbers of clients in the HIV clinics and limited staff. Enabling adolescents to do a self-assessment for depression on a tablet computer could possibly improve the detection of depression in this population. We set out to assess the detection and referral of depression among ALHIV in care in Uganda.

METHODS

This was a quasi-experimental study design with a historical control at Baylor College of Medicine of Children's Foundation. We conducted a retrospective chart review of 425 adolescents covering a 3-month period and documented the proportion screened for depression and referred to the clinic counsellors. From July to September 2022, eligible adolescents aged 10-19 years who had assented and consented self-assessed for depression using a Patient Health Questionnaire-Adolescent on a tablet computer-assisted self-interview (CASI). Adolescents who screened positive had a prompt on the tablet computers referring them to the counsellor for mental healthcare. We compared the proportions of participants screened for depression and referred to counsellors from clinic chart review and on the CASI using paired t-tests.

RESULTS

Out of 425 medical records reviewed, 54% (231/425) were females and the median age was 15 years. Of the participants who self-assessed on the CASI, 52% (222/425) were males and the median age of all participants was 16 years. Self-assessment on the CASI increased the rate of detection of depression from 0% to 23.3%. Of those referred on the CASI, 15% accessed care at the referral point.

CONCLUSION

The use of CASI improves the rate of detection of depression among ALHIV; however, there is a need to address the barriers to effective referral for mental health services.

Sudden gains in depression and anxiety during an online pain management programme for chronic pain

BACKGROUND

Chronic pain is associated with depression and anxiety symptoms. Pain management programms, delivered face-to-face or via the internet, can effectively help adults manage the impacts of chronic pain. Sudden gains are defined as substantial, rapid, and lasting symptom reductions that occur between consecutive treatment sessions and have been associated with better treatment outcomes in non-pain samples. This study examined whether adults with chronic pain report sudden gains in depression or anxiety symptoms during an 8-week online pain management programme, and whether sudden gains were associated with better treatment outcomes for depression or anxiety. Dominant theories of sudden gains argue that therapists are required for sudden gains to be maintained and improve treatment outcomes.

METHODS

Using data from a published randomized controlled trial (n = 338), sudden gains and treatment outcomes were compared across three levels of therapist guidance provided alongside the programme: weekly, optional, and self-guided.

RESULTS

Similar rates of sudden gains were observed in depression (22%) and anxiety (24%) across the treatment period, and most sudden gains occurred between Weeks 1 and 2 of treatment. Therapist guidance was not associated with sudden gains; higher baseline symptom severity emerged as the only consistent predictor of sudden gain status. No significant differences in treatment outcomes for depression or anxiety symptoms between sudden gainers and non-gainers were observed across therapist guidance conditions.

CONCLUSIONS

These results do not support an association between sudden gains in depression or anxiety symptoms and better post-treatment outcomes, at least for adults with chronic pain.

SIGNIFICANCE STATEMENT

Sudden gains in depression and anxiety symptoms were not associated with improved treatment outcomes for adults with chronic pain who participated in an online pain management programme, regardless of the level of therapist guidance provided. These findings suggest possible differences in symptom change in chronic pain samples compared to general population samples.

Utilization of Mental Health Provision, Epistemic Stance and Comorbid Psychopathology of Individuals with Complex Post-Traumatic Stress Disorders (CPTSD)-Results from a Representative German Observational Study

Background: Complex post-traumatic stress disorder (CPTSD) is a severely debilitating recently added symptom cluster in the International Classification of Diseases (ICD-11). So far, only limited information on mental health treatment-uptake and -satisfaction of individuals with CPTSD is available. The aim of this study is to investigate these aspects in a representative sample of the German general population. Methods: Participants completed the International Trauma Questionnaire (ITQ) to identify participants with CPTSD, as well as questionnaires on mental health treatment uptake and satisfaction, adverse childhood experiences, anxiety, depression, working ability, personality functioning, and epistemic trust. Results: Of the included n = 1918 participants, n = 29 (1.5%) fulfilled the criteria for CPTSD. Participants with CPTSD had received mental health treatment significantly more often than participants with PTSD or depression (65.5% vs. 58.8% vs. 31.6%; p = 0.031) but reported significantly less symptom improvement (52.9% vs. 78.0% vs. 80.0%; p = 0.008). Lower levels of epistemic trust were associated with higher CPTSD symptoms (p < 0.001). Conclusions: Our study shows that while the vast majority of individuals with CPTSD had received mental health treatment, subjective symptom improvement rates are not satisfactory. CPTSD was associated with a broad number of comorbidities and impairments in functioning. Lower levels of epistemic trust may partially explain worse treatment outcomes.

How much or how often? Examining the screening properties of the DSM cross-cutting symptom measure in a youth population-based sample

BACKGROUND

The DSM Level 1 Cross-Cutting Symptom Measure (DSM-XC) allows for assessing multiple psychopathological domains. However, its capability to screen for mental disorders in a population-based sample and the impact of adverbial framings (intensity and frequency) on its performance are unknown.

METHODS

The study was based on cross-sectional data from the 1993 Pelotas birth cohort in Brazil. Participants with completed DSM-XC and structured diagnostic interviews (n = 3578, aged 22, 53.6% females) were included. Sensitivity, specificity, positive (LR+), and negative (LR-) likelihood ratios for each of the 13 DSM-XC domains were estimated for detecting five internalizing disorders (bipolar, generalized anxiety, major depressive, post-traumatic stress, and social anxiety disorders) and three externalizing disorders (antisocial personality, attention-deficit/hyperactivity, and alcohol use disorders). Sensitivities and specificities >0.75, LR+ > 2 and LR- < 0.5 were considered meaningful. Values were calculated for the DSM-XC's original scoring and for adverbial framings.

RESULTS

Several DSM-XC domains demonstrated meaningful screening properties. The anxiety domain exhibited acceptable sensitivity and LR- values for all internalizing disorders. The suicidal ideation, psychosis, memory, repetitive thoughts and behaviors, and dissociation domains displayed acceptable specificity for all disorders. Domains also yielded small but meaningful LR+ values for internalizing disorders. However, LR+ and LR- values were not generally meaningful for externalizing disorders. Frequency-framed questions improved screening properties.

CONCLUSIONS

The DSM-XC domains showed transdiagnostic screening properties, providing small but meaningful changes in the likelihood of internalizing disorders in the community, which can be improved by asking frequency of symptoms compared to intensity. The DSM-XC is currently lacking meaningful domains for externalizing disorders.

Bidirectional associations between dietary diversity and depressive symptoms in Chinese adult women: A retrospective cohort study

OBJECTIVE

This study aimed to examine the bidirectional associations between dietary diversity and clinical depressive symptoms in adult women, and influencing factors of clinical depressive symptoms.

METHODS

This longitudinal study included a total of 22,385 participants, each of whom underwent at least two data collections. We used convenience sampling to recruit women from a health management center of a general hospital in southern China from April 2015 to December 2021. They completed an online self-reported health questionnaire, which included demographic characteristics, lifestyle information, the Dietary Diversity Scale (DDS), and the Patient Health Questionnaire-9.

RESULTS

New-onset depressive symptoms and low dietary diversity were observed in this study among 1285 and 3223 participants, respectively. Negative associations were observed between baseline low dietary diversity and new-onset depressive symptoms (P < 0.05) and between baseline depressive symptoms and low dietary diversity (P < 0.001). Cross-lagged panel analysis indicated that dietary diversity negatively and prospectively predicted depressive symptoms, but vice versa (P < 0.05). Strong evidence of a nonlinear association between DDS scores and incident depressive symptoms was found (P nonlinear < 0.05) regardless of whether the variables were adjusted. Besides, age, menarche age, physical activity, sleep duration, longer sedentary behavior and other lifestyle factors were influencing factors of depressive symptoms (P < 0.05).

CONCLUSIONS

The present study identified bidirectional associations between dietary diversity and depressive symptoms, and the associations were found to have a non-linear pattern. Adherence to dietary diversity and a healthy lifestyle could be effective non-pharmacological preventive measures to reduce the incidence of depressive symptoms.

Protein-enriched and anti-inflammatory dietary patterns, healthy lifestyle index and depressive symptoms: A cross-sectional study of 287,945 adults in China

OBJECTIVES

Depressive symptoms have a considerable negative impact on mental health. This study aimed to understand the relationship between the protein-enriched and anti-inflammatory dietary index scores, modified healthy lifestyle index scores (Modified HLIS), and depressive symptoms.

METHODS

This study used convenience sampling to conduct a single-center cross-sectional survey. From January 1, 2015 to December 31, 2020, a total of 287,945 Chinese adults from a health management center of a general hospital completed an online self-reported health questionnaire, which included demographic characteristics, the Dietary Diversity Scale, the Modified Healthy Lifestyle Index Scores and the Patient Health Questionnaire-9.

RESULTS

The higher anti-inflammatory dietary index scores (POR = 0.87; 95 % CI: 0.86-0.87; p < 0.001), moderate modified healthy lifestyle index scores (POR = 0.76; 95 % CI: 0.75-0.78; p < 0.001) and sufficient modified healthy lifestyle index scores (POR = 0.53; 95 % CI: 0.52-0.54; p < 0.001) were negatively associated with depressive symptoms, while the higher protein-enriched dietary index scores (POR = 1.01; 95 % CI: 1.01-1.02; p < 0.001) was positively correlated with depressive symptoms.

CONCLUSIONS

This study demonstrated that protein-enriched and anti-inflammatory dietary index scores, and multiple healthy lifestyles are associated depressive symptoms in adults.

A Systematic Review of the Psychometric Properties of the Patient Health Questionnaire-4 in Clinical and Nonclinical Populations

BACKGROUND

The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief instrument that measures depressive and anxiety symptoms. Although it has been frequently used in the last 15 years, no research has systematically reviewed its psychometric properties.

OBJECTIVE

This systematic review summarized, for the first time, the available published evidence on the psychometric properties of the PHQ-4.

METHODS

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered in the Prospective Register of Systematic Reviews, under the identification code CRD42022381809. The search strategy was applied in Medline, PsycINFO, Web of Science, and SCOPUS from 2009 (year of publication) to 2023 (present). Two independent reviewers performed screening, data extraction, and methodological quality assessment of the studies. The data was reported through a narrative synthesis.

RESULTS

In total, 26 studies involving 93,466 participants from 19 countries, with clinical and nonclinical samples, were included. The two-factor structure was the most frequent, being invariant according to gender, age, geographic location, income, educational level, and language. The internal consistency was adequate for distress (α from 0.72 to 0.88), as well as for depression (α from 0.65 to 0.81) and anxiety (α from 0.74 to 0.84). The temporal stability of the instrument was verified through test-retest reliability, reporting an acceptable connection between both measures. Correlations with related measures were significant and in the expected direction.

CONCLUSIONS

The PHQ-4 is a reliable and valid instrument for screening depressive and anxiety symptoms, both for the clinical and nonclinical populations. Due to the brevity of its administration, the PHQ-4 could be a clinical tool that contributes to optimizing health resources.

ESSENCE: An Implementation Research Program to Scale Up Depression Care in Rural Communities

BACKGROUND

Task sharing may involve training nonspecialist health workers (NSHWs) to deliver brief mental health interventions. This approach is promising for reducing the global mental health treatment gap. However, capacity is limited for training large cadres of frontline workers in low- and middle-income countries, hindering uptake of these interventions at scale.

METHODS

The ESSENCE (enabling translation of science to service to enhance depression care) project in Madhya Pradesh, India, aims to address these challenges through two sequential randomized controlled trials. First, a training trial will evaluate the effectiveness and cost-effectiveness of digital training, compared with conventional face-to-face training, in achieving clinical competency of NSHWs in delivering an intervention for depression. This initial trial will be followed by an implementation trial aimed at evaluating the effectiveness of a remote enhanced implementation support, compared with routine implementation support, in addressing barriers to delivery of depression care in primary care facilities.

RESULTS

This project involved developing and pilot testing a scalable smartphone-based program for training NSHWs to deliver a brief psychological intervention for depression screening. This initial research guided a randomized trial of a digital training approach with NSHWs to evaluate the effectiveness of this approach. This trial will be followed by a cluster-randomized trial to evaluate the effectiveness of remote implementation support in ensuring efficient delivery of depression care in primary care facilities.

NEXT STEPS

Findings from these trials may inform sustainable training and implementation support models to integrate depression care into primary care for scale-up in resource-constrained settings.

Cognition and psychological well-being in adults with post COVID-19 condition and analyses of symptom sequelae

OBJECTIVE

As the coronavirus disease 2019 (COVID-19) pandemic moves into its fourth year, gaining a better clinical understanding of individuals with post COVID-19 condition is paramount. The current study examined the neurocognitive and psychological status of adults with post COVID-19 condition, as well as explored the impact of high psychological burden on objective neurocognitive functioning and the relationship between subjective cognitive concerns and objective neurocognitive findings.

METHOD

Valid neuropsychological assessments were completed with 51 symptomatic adults who were 297.55 days, on average, following a confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Participants completed brief self-report depression, anxiety, and PTSD questionnaires, a questionnaire with subjective ratings of cognitive abilities, and standardized neurocognitive tests that examined performance validity, attention, processing speed, verbal learning and memory, naming, visual construction, and executive functioning.

RESULTS

The participants were mostly Caucasian (80.39%), middle-aged (average 47.37 years), women (82.35%), who were never hospitalized (86.27%). Despite all individuals reporting cognitive problems in daily life, mean performances on objective testing did not reveal any neurocognitive deficits (at or below the 8th percentile) at a group level. Approximately half (49.02%) of the participants reported co-occurring mental health symptoms that were considered clinically elevated based on questionnaire results. High psychological symptom burden was associated with greater subjective cognitive difficulties but did not result in neurocognitive dysfunction on objective testing.

CONCLUSIONS

This study contributes to the literature regarding post COVID-19 condition in adults including the relationship between the cognitive and psychological symptoms. Results are summarized in key clinical learning points.

Patient Health Questionnaire-9: A clinimetric analysis

OBJECTIVE

The Patient Health Questionnaire-9 (PHQ-9) is a widely used self-report measure of depression whose psychometric properties were found to be merely acceptable. Insufficient attention has been devoted to its clinimetric validity, while its clinical utility is still debated, particularly for assessing depression severity. This is the first study to test the PHQ-9 construct validity and clinical utility based on clinimetric principles.

METHODS

An online survey of 3,398 participants was conducted. Item response theory models (Rasch and Mokken analyses) were used to assess the PHQ-9 validity and determine its clinical utility.

RESULTS

Fit to the Rasch model was achieved after adjusting the sample size. Items 2, 4, 6, and 9 over-discriminated, while items 1, 5, and 7 under-discriminated. Local dependency between items 2 and 6 was indicated. The PHQ-9 was not unidimensional. A Loevinger's coefficient of 0.49 was found, indicating an acceptable level of scalability.

CONCLUSION

The PHQ-9 is an instrument with potential clinical utility as an overall index of depression, mainly for screening purposes. Substantial revision, particularly in the wording of over- and under-discriminating items, is needed.

Association between dietary diversity, sedentary time outside of work and depressive symptoms among knowledge workers: a multi-center cross-sectional study

BACKGROUND

Low-diversity diets and sedentary status are risk factors for depressive symptoms, while knowledge workers were ignored before. The purpose of this current study was to examine the relationship between dietary diversity, sedentary time spent outside of work, and depressive symptoms among knowledge workers.

STUDY DESIGN AND METHODS

This was a multicenter and cross-sectional design that included 118,723 knowledge workers. Participants self-reported online between January 2018 and December 2020. Demographic information, the Dietary Diversity Scale, the Patient Health Questionnaire-9, dietary habits (which included eating three meals on time, midnight snacking, overeating, social engagement, coffee consumption, sugary drink consumption, smoking and alcohol use), sedentary time spent outside of work and physical activity were investigated.

RESULTS

The relationships between demographic information, dietary habits and dietary diversity, and depressive symptoms were estimated. Compared with the first and second levels of dietary diversity, the third level of dietary diversity (OR: 0.91; 95% CI: 0.84-0.98) reduced the risk of depressive symptoms. Knowledge workers with different degrees of sedentary status (2-4 h (OR: 1.11; 95% CI: 1.07-1.14), 4-6 h (OR: 1.21; 95% CI: 1.17-1.26), and > 6 h (OR: 1.49; 95% CI: 1.43-1.56), presented a progressively higher risk of depressive symptoms.

CONCLUSION

High amounts of sedentary time spent after work and low levels of dietary diversity are risk factors for depressive symptoms. In addition, an irregular diet and overeating are also major risk factors for knowledge workers.

Accuracy of a Single Financial Security Question to Screen for Social Needs

OBJECTIVES

Screening for social needs is recommended during clinical encounters but multi-item questionnaires can be burdensome. We evaluate if a single question about financial stress can be used to prescreen for food insecurity, housing instability, or transportation needs.

METHODS

We use retrospective medical record data from children (<11 years) seen at 45 primary pediatric care offices in 2022. Social needs screening was automated at well child visits and could be completed by the parent/guardian via the patient portal, tablet in the waiting room, or verbally with staff. We report the area under the receiver operating curve for the 5 response options of the financial stress question as well as sensitivity and specificity of the financial stress question ("not hard at all" vs any other response) to detect other reported social needs.

RESULTS

Of 137 261 eligible children, 130 414 (95.0%) had social needs data collected. Seventeen percent of respondents reported a housing, food, or transportation need. The sensitivity of the financial stress question was 0.788 for any one or more of the 3 other needs, 0.763 for food insecurity, 0.743 for housing instability, and 0.712 for transportation needs. Using the financial stress question as the first-step of a screening process would miss 9.7% of the families who reported food insecurity, 22.6% who reported housing instability, and 33.0% who reported transportation needs.

CONCLUSIONS

A single question screener about financial stress does not function well as a prescreen because of low sensitivity to reports of food insecurity, housing instability, and transportation needs.

Adding online storytelling-based acceptance and commitment therapy to antidepressant treatment for primary care patients: a randomized clinical trial

Depression is most often treated in primary care, where the prevailing treatment is antidepressant medication. Primary care patients with depression are less likely to be exposed to psychosocial interventions, despite evidence suggesting many of these treatments are effective. An example is acceptance and commitment therapy (ACT), a behavioral treatment for depression with a growing evidence base. A self-guided ACT intervention with a peer narrative (i.e. storytelling) format was developed with the intention of creating a treatment option for primary care patients that was more accessible than traditional psychotherapy. Titled LifeStories, the online program features videos of real individuals sharing coping skills for depression based on lived experiences and key ACT principles. A total of 93 primary care patients taking antidepressants were randomized to either continued antidepressant treatment alone or antidepressant treatment plus LifeStories for 4 weeks. There were no differences over time on depression severity and psychological inflexibility. However, LifeStories led to greater improvements in quality of life and increased patients' interest in additional treatment compared to antidepressant medication alone.Clinical trial pre-registration: ClinicalTrials.gov (NCT04757961).

"High dietary live microbe intake is correlated with reduced risk of depressive symptoms: A cross-sectional study of NHANES 2007-2016"

BACKGROUND

Recent research indicated that levels of dietary live microorganisms were inconsistently associated with the prevalence of depressive symptoms. This study aimed to investigate the correlation between consumption of live microorganisms and symptoms of depression.

METHODS

Data on 21,653 study participants were obtained from the National Health and Nutrition Examination Survey (NHANES). Dietary information was assessed using a self-report questionnaire. Depressive status was assessed using the Patient Health Questionnaire (PHQ-9). Generalized linear model, restricted cubic spline (RCS), and subgroup analyses were performed in this study.

RESULTS

After full adjustment for confounders, participants in the moderate-dietary microbe intake group had a lower prevalence of depressive symptoms than those in the lowest intake group [odds ratio (OR): 0.813, 95 % confidence interval (CI): 0.678-0.974, P = 0.026, and pseudo R2 = 0.12]. Participants in the highest-dietary microbe intake group had a lower prevalence of depressive symptoms than those in the lowest intake group (OR: 0.714, 95 % CI: 0.586-0.870, P = 0.001, and pseudo R2 = 0.12). An L-shaped dose-response relationship was observed in the RCS (the P value for nonlinear relationship = 0.007). In subgroup analyses, participants with male identity, normal weight, and high physical activity (PA) level showed a substantial correlation between dietary live microbe consumption and depressive symptoms (all P values for interaction <0.050).

LIMITATIONS

This study was limited by its cross-sectional study design, and self-reported dietary live microbe consumption and depressive symptoms.

CONCLUSIONS

A high dietary live microbe intake was nonlinearly correlated with a lower prevalence of depressive symptoms.

Patient Health Questionnaire-9 Item Pairing Predictiveness for Prescreening Depressive Symptomatology: Machine Learning Analysis

BACKGROUND

Anhedonia and depressed mood are considered the cardinal symptoms of major depressive disorder. These are the first 2 items of the Patient Health Questionnaire (PHQ)-9 and comprise the ultrabrief PHQ-2 used for prescreening depressive symptomatology. The prescreening performance of alternative PHQ-9 item pairings is rarely compared with that of the PHQ-2.

OBJECTIVE

This study aims to use machine learning (ML) with the PHQ-9 items to identify and validate the most predictive 2-item depressive symptomatology ultrabrief questionnaire and to test the generalizability of the best pairings found on the primary data set, with 6 external data sets from different populations to validate their use as prescreening instruments.

METHODS

All 36 possible PHQ-9 item pairings (each yielding scores of 0-6) were investigated using ML-based methods with logistic regression models. Their performances were evaluated based on the classification of depressive symptomatology, defined as PHQ-9 scores ≥10. This gave each pairing an equal opportunity and avoided any bias in item pairing selection.

RESULTS

The ML-based PHQ-9 items 2 and 4 (phq2&4), the depressed mood and low-energy item pairing, and PHQ-9 items 2 and 8 (phq2&8), the depressed mood and psychomotor retardation or agitation item pairing, were found to be the best on the primary data set training split. They generalized well on the primary data set test split with area under the curves (AUCs) of 0.954 and 0.946, respectively, compared with an AUC of 0.942 for the PHQ-2. The phq2&4 had a higher AUC than the PHQ-2 on all 6 external data sets, and the phq2&8 had a higher AUC than the PHQ-2 on 3 data sets. The phq2&4 had the highest Youden index (an unweighted average of sensitivity and specificity) on 2 external data sets, and the phq2&8 had the highest Youden index on another 2. The PHQ-2≥2 cutoff also had the highest Youden index on 2 external data sets, joint highest with the phq2&4 on 1, but its performance fluctuated the most. The PHQ-2≥3 cutoff had the highest Youden index on 1 external data set. The sensitivity and specificity achieved by the phq2&4 and phq2&8 were more evenly balanced than the PHQ-2≥2 and ≥3 cutoffs.

CONCLUSIONS

The PHQ-2 did not prove to be a more effective prescreening instrument when compared with other PHQ-9 item pairings. Evaluating all item pairings showed that, compared with alternative partner items, the anhedonia item underperformed alongside the depressed mood item. This suggests that the inclusion of anhedonia as a core symptom of depression and its presence in ultrabrief questionnaires may be incompatible with the empirical evidence. The use of the PHQ-2 to prescreen for depressive symptomatology could result in a greater number of misclassifications than alternative item pairings.

Assessing the differential item functioning of PHQ-9 items for diverse racial and ethnic adults with mental health and/or substance use disorder diagnoses: A retrospective cohort study

BACKGROUND

Improving health equity in depression care and suicide screening requires that measures like the Patient Health Questionnaire 9 (PHQ-9) function similarly for diverse racial and ethnic groups. We evaluated PHQ-9 differential item functioning (DIF) between racial/ethnic groups in a retrospective cohort study of secondary electronic health record (EHR) data from eight healthcare systems.

METHODS

The population (n = 755,156) included patients aged 18-64 with mental health and/or substance use disorder (SUD) diagnoses who had a PHQ-9 with no missing item data in the EHR for primary care or mental health visits between 1/1/2009-9/30/2017. We drew two random samples of 1000 from the following racial/ethnic groups originally recorded in EHRs (n = 14,000): Hispanic, and non-Hispanic White, Black, Asian, American Indian/Alaska Native, Native Hawaiian/Other Pacific Islander, multiracial. We assessed DIF using iterative hybrid ordinal logistic regression and item response theory with p < 0.01 and 1000 Monte Carlo simulations, where change in model R2 > 0.01 represented non-negligible (e.g., clinically meaningful) DIF.

RESULTS

All PHQ-9 items displayed statistically significant, but negligible (e.g., clinically unmeaningful) DIF between compared groups. The negligible DIF varied between random samples, although six items showed negligible DIF between the same comparison groups in both random samples.

LIMITATIONS

Our findings may not generalize to disaggregated racial/ethnic groups or persons without mental health and/or SUD diagnoses.

CONCLUSIONS

We found the PHQ-9 had clinically unmeaningful cross-cultural DIF for adult patients with mental health and/or SUD diagnoses. Future research could disaggregate race/ethnicity to discern if within-group identification impacts PHQ-9 DIF.

Sensitivity and specificity of the Patient Health Questionnaire (PHQ-9, PHQ-8, PHQ-2) and General Anxiety Disorder scale (GAD-7, GAD-2) for depression and anxiety diagnosis: a cross-sectional study in a Peruvian hospital population

OBJECTIVES

The Patient Health Questionnaire (PHQ) and Generalised Anxiety Disorder Scale (GAD) are widely used screening tools, but their sensitivity and specificity in low-income and middle-income countries are lower than in high-income countries. We conducted a study to determine the sensitivity and specificity of different versions of these scales in a Peruvian hospital population.

DESIGN

Our study has a cross-sectional design.

SETTING

Our participants are hospitalised patients in a Peruvian hospital. The gold standard was a clinical psychiatric interview following ICD-10 criteria for depression (F32.0, F32.1, F32.2 and F32.3) and anxiety (F41.0 and F41.1).

PARTICIPANTS

The sample included 1347 participants. A total of 334 participants (24.8%) were diagnosed with depression, and 28 participants (2.1%) were diagnosed with anxiety.

RESULTS

The PHQ-9's≥7 cut-off point showed the highest simultaneous sensitivity and specificity when contrasted against a psychiatric diagnosis of depression. For a similar contrast against the gold standard, the other optimal cut-off points were: ≥7 for the PHQ-8 and ≥2 for the PHQ-2. In particular, the cut-off point ≥8 had good performance for GAD-7 with sensitivity and specificity, and cut-off point ≥10 had lower levels of sensitivity, but higher levels of specificity, compared with the cut-off point of ≥8. Also, we present the sensitivity and specificity values of each cut-off point in PHQ-9, PHQ-8, PHQ-2, GAD-7 and GAD-2. We confirmed the adequacy of a one-dimensional model for the PHQ-9, PHQ-8 and GAD-7, while all PHQ and GAD scales showed good reliability.

CONCLUSIONS

The PHQ and GAD have adequate measurement properties in their different versions. We present specific cut-offs for each version.

Online Patient-Reported Outcome Measure Engagement Is Dependent on Demographics and Locality: Findings From an Observational Cohort

OBJECTIVE

Online patient-reported outcome measures (PROMs) enable remote collection of perceptions of health status, function, and well-being. We aimed to explore patterns of PROM completion in patients with early inflammatory arthritis (EIA) recruited to the National Early Inflammatory Arthritis Audit (NEIAA).

METHODS

NEIAA is an observational cohort study design; we included adults from this cohort with a new diagnosis of EIA from May 2018 to March 2020. The primary outcome was PROM completion at baseline, 3 months, and 12 months. Mixed effects logistic regression and spatial regression models were used to identify associations between demographics (age, gender, ethnicity, deprivation, smoking, and comorbidity), clinical commissioning groups, and PROM completion.

RESULTS

Eleven thousand nine hundred eighty-six patients with EIA were included, of whom 5331 (44.5%) completed at least 1 PROM. Patients from ethnic minority backgrounds were less likely to return a PROM (adjusted odds ratio [aOR] 0.57, 95% CI 0.48-0.66). Greater deprivation (aOR 0.73, 95% CI 0.64-0.83), male gender (aOR 0.86, 95% CI 0.78-0.94), higher comorbidity burden (aOR 0.95, 95% CI 0.91-0.99), and current smoker status (aOR 0.73, 95% CI 0.64-0.82) also reduced odds of PROM completion. Spatial analysis identified 2 regions with high (North of England) and low (Southeast of England) PROM completion.

CONCLUSION

We define key patient characteristics (including ethnicity) that influence PROM engagement using a national clinical audit. We observed an association between locality and PROM completion, with varying response rates across regions of England. Completion rates could benefit from targeted education for these groups.

"How's your mood": Recorded physician mental health conversations with Chinese and Latino patients in routine primary care visits

OBJECTIVE

Patient-physician communication patterns may influence discussions around depressive symptoms and contribute to engagement in depression care among racial/ethnic minority adults. We examined patient-physician communication about depressive symptoms during routine primary care visits with Chinese and Latino patients with and without language barriers.

METHODS

We examined 17 audio-recorded conversations between primary care physicians and Chinese (N = 7) and Latino (N = 10) patients who discussed mental health during their visit and reported depressive symptoms on a post-visit survey. Conversations (in English, Cantonese, Mandarin, Hoisan-wa, Spanish) were transcribed and translated by bilingual/bicultural research assistants and analyzed using inductive and deductive thematic and discourse analysis.

RESULTS

Patients initiated mental health discussion in eleven visits. Physicians demonstrated care in word choice and sometimes avoided openly mentioning depression; this could contribute to miscommunication around symptoms and treatment goals. Interpreters had difficulty finding single words to convey terms used by either patients or physicians.

CONCLUSION

Patients and doctors appeared willing to discuss mental health; however, variability in terminology presented challenges in mental health discussions in this culturally and linguistically diverse sample.

PRACTICE IMPLICATIONS

Further understanding patient preferred terminology about mental health symptoms and interpreter training in these terms could improve patient-physician communication about depressive symptoms and treatment preferences.

New cut-off points of PHQ-9 and its variants, in Costa Rica: a nationwide observational study

The PHQ-9 questionnaire is a screening test worldwide used to measure depression. But it cannot be used in Costa Rica, due to the fact that it has not previously been validated for its population. The present study aims to show the validation of the PHQ-9 questionnaire and its variants (PHQ-2, PHQ-4, PHQ-8) in a population sample of adults residing in Costa Rica. A sample was collected (n = 1162) using a self-administered questionnaire. Confirmatory Factor Analysis (CFA), Receiver Operating Characteristic (ROC) curve, and Multiple Group Confirmatory Factor Analysis (MGCFA) were tested. One factor was found that explained 73.33% of the variance with excellent internal consistency (α = 0.928). Goodness-of-fit measures were adequate (RMSEA = 0.107; CFI = 0.948), as was diagnostic power at a cut-off of 10 (78.60 for Sensitivity and 27.95 for 1-Specificity). External validation indices were good (r = 0.843 with GAD-7, r = - 0.647 with RS14, and r = 0.301 with FCV19S), and the model showed invariance by sex (∆χ2 = 27.90; df = 27; p < 0.001). Additionally, new cut-off points were proposed for PHQ-9 and its variants for Costa Rican male, female, and general populations. The PHQ-9 and its variants (PHQ-2, 4, and 8) are valid tools for detecting depression (and anxiety for PHQ-4) in Costa Rican population. In addition, new cut-off points differentiated by sex are proposed.

Measuring Dysfunctional Grief due to a COVID-19 Loss: A Kurdish Validation Study of the Pandemic Grief Scale

Millions of people are grieving the loss of someone who died of COVID-19. The current study aims to validate a Kurdish version of the Pandemic Grief Scale which is a brief English-language mental health screener to identify cases of dysfunctional grief associated with a COVID-19 death. We recruited 501 participants. Participants completed the PGS, WSAS, PHQ-9, and Optimism scales. The factor structure, reliability, and validity of the PGS were analyzed. Using exploratory factor analysis (N1 = 300), we derived an one-factor structure. In confirmatory factor analysis (N2 = 201), the one-factor model showed good to excellent fitness. The PGS was positively correlated with PHQ-4, and WSAS and negatively correlated with optimism. The scale was internally consistent with a Cronbach's alpha of .79. These results support that the Kurdish version of the PGS is a valid and reliable assessment to assess the severity of dysfunctional grief associated with a COVID-19 death.

The risk of obstructive sleep apnea is highly correlated with depressive symptoms among the Korean adults population: results from the 2020 Korea National Health and Nutrition Examination Survey

OBJECTIVES

We aimed to examine the association between Obstructive Sleep Apnea (OSA) risk, health behaviors, and depressive symptoms in a representative Korean sample.

METHODS

Cross-sectional data from the 2020 Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed. The sample included 4,352 adults aged 40 years and older. Multiple linear regression analysis was performed to examine the association between OSA risk, health behaviors, and depressive symptoms.

RESULTS

In total, 23.1% of the participants reported a high risk of OSA. Of the respondents, 39.8%, 19.0%, 27.2%, and 8.7% reported hypertension, snoring, tiredness, and observed apnea, respectively. The prevalence of moderate-severe depressive symptoms among adults with high-risk OSA was 7.5%. The significant associations between OSA risk and sex with PHQ-9 were shown in univariate linear regression. In the multiple linear regression analysis, the association between high risk of OSA and PHQ-9 showed in total (B = 1.58; P < 0.001), male (B = 1.21; P < 0.001), and female (B = 1.93; P < 0.001).

CONCLUSIONS

A high risk of OSA was associated with an increased prevalence of depressive symptoms. Monitoring the risk factors of depressive symptoms, including OSA, or unhealthy behaviors may decrease the mental health issues of middle-aged and older adults.

Prevalence and factors associated with mental health problems of psychological distress and depression among rural Victorians - analysis of cross-sectional data (Crossroads II)

BACKGROUND

Research suggests that rates of mental illness are similar in rural and urban Australia, although there are significant workforce shortages in rural regions along with higher rates of chronic disease and obesity and lower levels of socioeconomic status. However, there are variations across rural Australia and limited local data on mental health prevalence, risk, service use and protective factors. This study describes the prevalence of self-reported mental health problems of psychological distress and depression, in a rural region in Australia and aims to identify the factors associated with these problems.

METHODS

The Crossroads II study was a large-scale cross-sectional study undertaken in the Goulburn Valley region of Victoria, Australia in 2016-18. Data were collected from randomly selected households across four rural and regional towns and then screening clinics from individuals from these households. The main outcome measures were self-reported mental health problems of psychological distress assessed by the Kessler 10 and depression assessed by Patient Health Questionnaire-9. Unadjusted odd ratios and 95% confidence intervals of factors associated with the two mental health problems were calculated using simple logistic regression with multiple logistic regression using hierarchical modelling to adjust for the potential confounders.

RESULTS

Of the 741 adult participants (55.6% females), 67.4% were aged ≥ 55 years. Based on the questionnaires, 16.2% and 13.6% had threshold-level psychological distress and depression, respectively. Of those with threshold-level K-10 scores, 19.0% and 10.5% had seen a psychologist or a psychiatrist respectively while 24.2% and 9.5% of those experiencing depression had seen a psychologist or a psychiatrist, respectively in the past year. Factors such as being unmarried, current smoker, obesity, were significantly associated with a higher prevalence of mental health problems whereas physical activity, and community participation reduced the risk of mental health problems. Compared to rural towns, the regional town had higher risk of depression which was non-significant after adjusting for community participation and health conditions.

CONCLUSIONS

The high prevalence of psychological distress and depression in this rural population was consistent with other rural studies. Personal and lifestyle factors were more relevant to mental health problems than degree of rurality in Victoria. Targeted lifestyle interventions could assist in reducing mental illness risk and preventing further distress.

Understanding the impact of an AI-enabled conversational agent mobile app on users' mental health and wellbeing with a self-reported maternal event: a mixed method real-world data mHealth study

Background

Maternal mental health care is variable and with limited accessibility. Artificial intelligence (AI) conversational agents (CAs) could potentially play an important role in supporting maternal mental health and wellbeing. Our study examined data from real-world users who self-reported a maternal event while engaging with a digital mental health and wellbeing AI-enabled CA app (Wysa) for emotional support. The study evaluated app effectiveness by comparing changes in self-reported depressive symptoms between a higher engaged group of users and a lower engaged group of users and derived qualitative insights into the behaviors exhibited among higher engaged maternal event users based on their conversations with the AI CA.

Methods

Real-world anonymised data from users who reported going through a maternal event during their conversation with the app was analyzed. For the first objective, users who completed two PHQ-9 self-reported assessments (n = 51) were grouped as either higher engaged users (n = 28) or lower engaged users (n = 23) based on their number of active session-days with the CA between two screenings. A non-parametric Mann-Whitney test (M-W) and non-parametric Common Language effect size was used to evaluate group differences in self-reported depressive symptoms. For the second objective, a Braun and Clarke thematic analysis was used to identify engagement behavior with the CA for the top quartile of higher engaged users (n = 10 of 51). Feedback on the app and demographic information was also explored.

Results

Results revealed a significant reduction in self-reported depressive symptoms among the higher engaged user group compared to lower engaged user group (M-W p = .004) with a high effect size (CL = 0.736). Furthermore, the top themes that emerged from the qualitative analysis revealed users expressed concerns, hopes, need for support, reframing their thoughts and expressing their victories and gratitude.

Conclusion

These findings provide preliminary evidence of the effectiveness and engagement and comfort of using this AI-based emotionally intelligent mobile app to support mental health and wellbeing across a range of maternal events and experiences.

The temporal relationship of alcohol use and subsequent self-reported health status among people with HIV

Background

Alcohol use among people with HIV is associated with worse HIV treatment outcomes. Its impact on self-reported health status is unclear.

Setting

Longitudinal cohort of people with HIV engaged in care across 7 clinics participating in the Centers for AIDS Research Network of Integrated Care Systems between January 2011 and June 2014.

Methods

A total of 5046 participants were studied. A quantile regression model estimated the association of alcohol use levels with subsequent self-reported health status score, accounting for multiple covariates including depressive symptoms. Women, men who have sex with women, and men who have sex with men were analyzed separately.

Results

Prevalence of heavy alcohol use was 21%, 31%, and 37% among women, men who have sex with women, and men who have sex with men, respectively. Women with heavy alcohol use had a subsequently decreased median self-reported health status score compared to women with no or moderate alcohol use (odds ratio [OR]: 0.76; 95% confidence interval [CI]: 0.58-0.99); this association was not explained by the presence of depressive symptoms. There was no observed association of alcohol use level on subsequent self-reported health status among men who have sex with women. Men who have sex with men reporting no alcohol use had a subsequently decreased median self-reported health status compared to moderate alcohol use (OR: 0.88; 95% CI: 0.80-0.97).

Conclusion

Heavy alcohol use is associated with worsened self-reported health status at subsequent visits among women with HIV and not men with HIV.

Brief self-affirmation intervention for adults with psoriasis for reducing anxiety and depression and boosting well-being: Evidence from a randomized controlled trial

BACKGROUND

There are relatively few studies to address mental health implications of self-affirming, especially across groups experiencing a chronic health condition. In this study, short- and longer-term effects of a brief self-affirmation intervention framed in terms of implementation intentions (if-then plans with self-affirming cognitions; S-AII) were evaluated against an active control group (non-affirming implementation intentions; N-AII), matched to the target condition, and mere goal intention condition (a non-active control) in adults with psoriasis. The three pre-registered primary outcomes captured depression, anxiety, and well-being.

METHODS

Adults with psoriasis (N = 175; M_age = 36.53, s.d. = 11.52) were randomized into S-AII, N-AII, or control. Participants' mental health outcomes were assessed prior to randomization (at baseline), at week 2 (post-intervention), and at a 1-month follow-up.

RESULTS

Linear mixed models were used and results were reported on the intention-to-treat principle. Analyses revealed that S-AII exerted significantly more improvement in the course of well-being (ds > 0.25), depressive symptoms (ds > -0.40), and anxiety (ds > -0.45) than the N-AII and control group at 2-week post-intervention. Though the differences between groups faded at 1-month follow-up, the within-group changes over time for S-AII in all mental health outcomes remained significant.

CONCLUSIONS

Brief and low-intensity S-AII intervention exerted in the short-term a considerable impact on mental health outcomes. The S-AII shows promising results as a relevant public mental health strategy for enhancing well-being and reducing psychological distress. Future studies could consider whether these effects can be further enhanced with booster interventions.

Multicenter Study of Utility and Acceptability of Depression and Anxiety Screening in Adolescents and Young Adults With Childhood-Onset Systemic Lupus

OBJECTIVE

To determine the utility and acceptability for depression and anxiety screening of adolescents and young adults (AYA) with childhood-onset systemic lupus erythematosus (cSLE) in the pediatric rheumatology setting.

METHODS

AYA with cSLE, ages 12-21 years, from 8 collaborating sites, were consecutively screened for depression and anxiety with the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder 7-item scale (GAD-7). Demographic and disease characteristics were collected, as well as patient-reported outcome measures using the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric profile-25. Acceptability of screening was assessed with postscreening surveys completed by AYA and parents. Chi-square and Wilcoxon rank sum tests examined the relationship between patient characteristics and history of previous screening. Spearman correlations examined relationships between screening scores, PROMIS domains, and other disease factors.

RESULTS

Among 106 AYA screened, 64 (60%) had been previously screened, 25 (24%) by general pediatricians. Thirty-two (30%) AYA screened positive, including 24% for depression, 17% for anxiety, and 14% for suicidal ideation. Depression and anxiety symptom severity were highly correlated with increased PROMIS domain scores for fatigue and pain interference and moderately correlated with increased pain severity, decreased mobility, and decreased peer relationships. Eighty-six percent of AYA and 95% of parents expressed comfort with screening in the pediatric rheumatology setting.

CONCLUSION

Depression, anxiety, and suicidal ideation are common among AYA with cSLE, and symptoms are correlated with important patient-reported outcomes. Mental health screening in the pediatric rheumatology setting was highly acceptable among AYA with cSLE and their parents.

Translating measurement into practice: Brazilian norms for the Patient Health Questionnaire (PHQ-9) for assessing depressive symptoms

OBJECTIVE

To provide practical norms for measuring depressive symptoms using the Patient Health Questionnaire 9 (PHQ-9) in Brazil using a state-of-art psychometrics analysis.

METHODS

We used a large and representative Brazilian dataset from the 'Pesquisa Nacional de Saúde - 2019'(PNS-2019), which includes 90,846 Brazilian citizens. First, to assess the scale structure, we assessed the unidimensional model using Confirmatory Factor Analysis (CFA). Second, we used Item Response Theory (IRT) to characterize depressive symptoms´ distribution. Then, we linked summed- and meanbased PHQ-9 scores with the IRT-based score by using generalized additive models. Finally, we generated percentiles, T scores, and a newly developed score, called D scores (decimal scores), to describe the PHQ-9 norms for Brazilian population.

RESULTS

CFA revealed a good fit to the unidimensional model, showing to be invariant to age and sex. IRT captured item-level information of the latent trait (reliable from 1 to 3 standard deviations above the mean). Brazilian norms were presented using summed-, T-scores, and D-scores.

CONCLUSIONS

This is the first study to define Brazilian´s norms for the PHQ-9 among a large representative sample, using robust psychometric tools. More precise PHQ-9 scores are now available and may be widely used in primary and specialized clinical care settings.

Effects of soothing images and soothing sounds on mood and well-being

OBJECTIVES

Mental health problems are increasing at an alarming rate, calling for the need for more cost-effective and easily accessible interventions. Visual images and sounds depicting nature have been found to have positive effects on individuals' mood and well-being; however, the combined effects of images and sounds have been scarcely investigated. This study therefore aimed to compare the mood effects of viewing nature-related soothing images versus listening to soothing sounds versus a combination of both.

METHODS

In this study, 149 participants aged 18-83 years old (M = 35.88, SD = 15.63; 72.5% female, male 26.8%, .7% transgender) were randomised into three intervention conditions: images only, sounds only or combined (images and sounds). Baseline depressive and anxiety symptoms were indexed, and four outcome variables (positive affect, negative affect, serenity affect and depressive mood states) were measured pre- and post-intervention.

RESULTS

Findings showed that all participants, regardless of group, reported a decrease in negative affect, positive affect and depressive mood as well as an increase in serenity affect (including feelings of soothe). However, there were no group differences. Exploratory analyses found that individuals with higher levels of depressive and anxiety symptoms at baseline experienced greater reduction in negative affect and depressive mood state, as well as a larger increase in serenity affect.

CONCLUSIONS

These findings therefore provide preliminary evidence that, upon further research and development, images and sounds depicting nature can potentially be developed for use as an effective tool to improve mood and well-being.

The first wave of COVID-19 and mental distress of physician residents in Brazil: a comparison between two cohorts

INTRODUCTION

The reorganization of healthcare systems to face the COVID-19 pandemic has led to concerns regarding psychological distress of healthcare workers, and training requirements of physician residents.

OBJECTIVE

To assess the influence of COVID-19 pandemic on depression, anxiety, burnout and training schedules of residents.

METHODS

Two independent cross-sectional studies (the first in November 2019 [control], the second in June 2020, during the first wave of COVID-19 pandemic) enrolling physician residents from Brazil, using online surveys. In each of them, we collected demographic and training program data, and assessed depression, anxiety and burnout through PHQ-2, GAD-2 and MBI (2-item version) scales, respectively. We controlled confounding variables with logistic regression analysis.

RESULTS

The COVID-19 cohort (n = 524) presented a briefer workload and had at least 1 day off per week more frequently, in relation to the control cohort (n = 1 419). The majority of residents (464/524, 89.5%) had a reduction in their duty hours, and believed they would need an extra training period after the end of the pandemic (399/524, 76.2%). The frequency of depression increased (46.0% vs. 58.8%, aOR = 1.64, 95% CI = 1.32-2.05), anxiety did not change (56.5% vs. 56.5%, aOR = 1.24, 95% CI = 0.99-1.55) and burnout decreased (37.0% vs. 26.1%, aOR = 0.77, 95% CI = 0.60-0.99). Sensitivity analysis did not change these results.

CONCLUSION

Mental distress is frequent among residents and associated with both training program and social environments. The consequences of the COVID-19 pandemic on training requirements should be specifically addressed by supervisors and policymakers, in a case-by-case basis. Psychological support must be provided to healthcare workers.

A new PHQ-2 for Chinese adolescents: identifying core items of the PHQ-9 by network analysis

BACKGROUND

The importance of preventing and treating adolescent depression has been gradually recognized in Chinese society, especially in the context of the COVID-19 pandemic. Early screening is the first step. The Patient Health Questionnaire-9 (PHQ-9) is a leading scale in the field of depression screening. To improve screening efficiency in large-scale screening, an even shorten scale is desirable. The PHQ-2, which only included two items measuring anhedonia and depressed mood, is an ultra-form of the PHQ-9. However, emerging evidence suggests that there may be a better short form for the PHQ-9, especially for adolescents. Therefore, using two large samples of Chinese adolescents, this study aimed to identify the core items of the PHQ-9 and examine the short form consisting of core items.

METHODS

Surveys were conducted among primary and middle school students in two Chinese cities with different economic levels during the COVID-19 pandemic. Two gender-balanced samples aged 10 to 17 (n_{Sample 1} = 67281, n_{Sample 2} = 16726) were collected. Network analysis was used to identify the core items of the PHQ-9, which were extracted to combine a short version. Reliability, concurrent validity, and the receiver operating characteristic curve (ROC) of the short form were examined. Analyses were gender-stratified.

RESULTS

Network analysis identified fatigue and depressed mood as core items in the PHQ-9 among Chinese adolescents. Items measuring Fatigue and Mood were combined to be a new PHQ-2 (PHQ-2 N). The PHQ-2 N displayed satisfactory internal consistency and current validity. Taking the PHQ-9 as a reference, the PHQ-2 N showed higher ROC areas and better sensitivity and specificity than the PHQ-2. The optimal cutoff score for the PHQ-2 N was 2 or 3.

CONCLUSIONS

Fatigue and depressed mood are the central symptoms of the depressive symptom network. The PHQ-2 N has satisfactory psychometric properties and can be used in rapid depression screening among Chinese adolescents.

Factors associated with worsened clinical symptoms of psoriasis and disease-related quality of life during the COVID-19 lockdown: A cross-sectional study

Objective

In this cross-sectional study, we aimed to evaluate the factors associated with psoriasis symptom worsening and impaired quality of life (QoL) in individuals with psoriasis during the COVID-19 pandemic lockdown.

Methods

During the second COVID-19 national lockdown (January-April 2021) in Lithuania, individuals diagnosed with psoriasis were invited to fill in an anonymous online survey including sociodemographic and life-style factors, psoriasis-related clinical symptoms, the Dermatology Life Quality Index (DLQI) and the Patients' Health Questionnaire (PHQ).

Results

A total of 297 respondents completed the survey. The majority of them (52.5%) reported worsened clinical symptoms of psoriasis during the COVID-19 lockdown period. In total, 43.1% of responders reported significant depressive symptoms (PHQ-9 ≥ 10) and 23.6% reported impaired disease-related QoL (DLQI > 10). The strongest predictor of psoriasis symptoms worsening was the need for changes in psoriasis treatment, with an odds ratio (OR) of 2.73 (95% CI 1.37-5.44, p = 0.004) and decreased income (OR = 2.33, 95% CI 1.30-4.17, p = 0.004). The strongest predictor of impaired QoL was male sex (OR = 3.35, 95% CI 1.70-6.59, p < 0.001). Contribution of specific depressive symptoms was evident for both models.

Conclusion

Worsening of psoriasis symptoms during the COVID-19 lockdown was associated with decreased income, psoriasis treatment changes and depression symptoms. Impaired QoL was associated with male sex, symptom worsening and depression. Specific depression symptoms may have contributed to more symptom worsening and impaired QoL than the depressive symptomatology as a whole.

Comparing the effectiveness of existing anxiety treatment options among patients evaluated for chest pain and anxiety in the emergency department setting: Study protocol for the PACER pragmatic randomized comparative effectiveness trial

BACKGROUND

Anxiety disorders are a common underlying cause of symptoms among low-risk chest pain patients evaluated in the emergency department setting. However, anxiety is often undiagnosed and undertreated in any setting, and causes considerable functional impairment to work, family, and social life.

OBJECTIVES

The Patient-Centered Treatment of Anxiety after Low-Risk Chest Pain in the Emergency Room (PACER) study is a pragmatic randomized trial to test the comparative effectiveness of existing anxiety treatments of graduated intensities and determine what options work best for patient subgroups based on anxiety severity and other comorbidities.

METHODS

The PACER trial will enroll 375 emergency department patients with low-risk chest pain and anxiety (GAD-7 score ≥ 8) and randomize them to either: 1) referral to primary care with enhanced care coordination, 2) online self-administered cognitive behavioral therapy with guided peer support, or 3) therapist-administered cognitive behavior therapy. Outcomes include anxiety symptoms (primary) as well as physical symptom burden, depression symptoms, functional impairment, ED recidivism, and occurrence of major adverse cardiac events. Statistical analyses will be conducted primarily using linear mixed models to perform a repeated measures analysis of patient-reported outcomes, assessed at 3, 6, 9, and 12-month follow-ups.

DISCUSSION

PACER is an innovative and pragmatic clinical trial that will compare the effectiveness of several evidence-based telecare-delivered treatments for anxiety. Results have the potential to inform clinical guidelines for evaluation and management of low-risk chest pain patients and promote adoption of findings in ED departments across the country.

Depression in association with neutrophil-to-lymphocyte, platelet-to-lymphocyte, and advanced lung cancer inflammation index biomarkers predicting lung cancer survival

Lung cancer is a product of inflammation and a dysfunctional immune system, and depression has similar dysregulation. Depression disproportionately affects lung cancer patients, having the highest rates of all cancers. Systemic inflammation and depression are both predictive of non-small cell lung cancer (NSCLC) survival, but the existence and extent of any co-occurrence is unknown. Studied is the association between systemic inflammation ratio (SIR) biomarker levels and patients' depressive symptoms, with the hypothesis that depression severity would be significantly associated with prognostically poor inflammation. Newly diagnosed stage-IV non-small cell lung cancer (NSCLC; N = 186) patients were enrolled (ClinicalTrials.gov Identifier: NCT03199651) and blood draws and depression self-reports (Patient Health Questionnaire-9) were obtained. For SIRs, cell counts of neutrophils (N), lymphocytes (L), and platelets (P) were abstracted for ratio (R) calculations for NLR, PLR, and the Advanced Lung cancer Inflammation Index (ALI). Patients were followed and biomarkers were tested as predictors of 2-year overall survival (OS) to confirm their relevance. Next, multivariate linear regressions tested associations of depression with NLR, PLR, and ALI. Overall 2-year mortality was 61% (113/186). Cox model analyses confirmed higher NLR [hazard ratio (HR) = 1.91; p = 0.001] and PLR (HR = 2.08; p<0.001), along with lower ALI (HR = 0.53; p = 0.005), to be predictive of worse OS. Adjusting for covariates, depression was reliably associated with biomarker levels (p ≤ 0.02). Patients with moderate/severe depressive symptoms were 2 to 3 times more likely to have prognostically poor biomarker levels. Novel data show patients' depressive symptoms were reliably associated with lung-relevant systemic inflammation biomarkers, all assessed at diagnosis/pretreatment. The same SIRs were found prognostic for patients' 2-year OS. Intensive study of depression, combined with measures of cell biology and inflammation is needed to extend these findings to discover mechanisms of depression toxicity for NSCLC patients' treatment responses and survival.

Relationship of Mindfulness with Depression, Self-Management, and Quality of Life in Type 2 Diabetes Mellitus: mindfulness is a Predictor of Quality of Life

Context

Mindfulness interventions have shown promising results in both psychological and clinical outcomes of type 2 diabetes mellitus. Depression, self-management, and quality of life (QOL) have shown improvement with mindfulness interventions; however, little is known about dispositional mindfulness and its relationship with depression, self-management, and QOL in type 2 diabetes mellitus.

Aims

The aim of this study is to assess the relationship of dispositional mindfulness with depression, self-management, and QOL in patients of type 2 diabetes.

Settings and Design

Noncommunicable disease outpatient department of a tertiary care medical center of East India. Cross-sectional study.

Subjects and Methods

Ninety-nine patients with type 2 diabetes completed the Five Facets Mindfulness Questionnaire, Diabetes Self-Management Questionnaire, and World Health Organization QOL BREF questionnaire and Hamilton Rating Scale for depression.

Statistical Analysis Used

Pearson's correlation and hierarchical regression analysis using the SPSS software version 20.0.

Results

Describing, acting with awareness, and nonjudging facets of mindfulness showed a negative correlation with depression (P < 0.05). Acting with awareness and nonreactivity to inner experience were positively correlated with the physical activity domains of self-management (P < 0.05). All facets of mindfulness showed a positive correlation with four domains of QOL. In hierarchical regression analysis, after controlling for sociodemographic and clinical variables, mindfulness predicted the psychological domain of QOL, explaining 31% of the variance (P ≤ 0.001). However, mindfulness did not predict depression or self-management.

Conclusions

Dispositional mindfulness is a strong predictor of QOL in type 2 diabetes mellitus and hence can be targeted with interventions to improve psychological outcomes.

Anxiety Disorders: A Review

Importance

Anxiety disorders have a lifetime prevalence of approximately 34% in the US, are often chronic, and significantly impair quality of life and functioning.

Observations

Anxiety disorders are characterized by symptoms that include worry, social and performance fears, unexpected and/or triggered panic attacks, anticipatory anxiety, and avoidance behaviors. Generalized anxiety disorder (6.2% lifetime prevalence), social anxiety disorder (13% lifetime prevalence), and panic disorder (5.2% lifetime prevalence) with or without agoraphobia are common anxiety disorders seen in primary care. Anxiety disorders are associated with physical symptoms, such as palpitations, shortness of breath, and dizziness. Brief screening measures applied in primary care, such as the Generalized Anxiety Disorder-7, can aid in diagnosis of anxiety disorders (sensitivity, 57.6% to 93.9%; specificity, 61% to 97%). Providing information about symptoms, diagnosis, and evidence-based treatments is a first step in helping patients with anxiety. First-line treatments include pharmacotherapy and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs, eg, sertraline) and serotonin-norepinephrine reuptake inhibitors (SNRIs, eg, venlafaxine extended release) remain first-line pharmacotherapy for generalized anxiety disorder, social anxiety disorder, and panic disorder. Meta-analyses suggest that SSRIs and SNRIs are associated with small to medium effect sizes compared with placebo (eg, generalized anxiety disorder: standardized mean difference [SMD], -0.55 [95% CI, -0.64 to -0.46]; social anxiety disorder: SMD, -0.67 [95% CI, -0.76 to -0.58]; panic disorder: SMD, -0.30 [95% CI, -0.37 to -0.23]). Cognitive behavioral therapy is the psychotherapy with the most evidence of efficacy for anxiety disorders compared with psychological or pill placebo (eg, generalized anxiety disorder: Hedges g = 1.01 [large effect size] [95% CI, 0.44 to 1.57]; social anxiety disorder: Hedges g = 0.41 [small to medium effect] [95% CI, 0.25 to 0.57]; panic disorder: Hedges g = 0.39 [small to medium effect[ [95% CI, 0.12 to 0.65]), including in primary care. When selecting treatment, clinicians should consider patient preference, current and prior treatments, medical and psychiatric comorbid illnesses, age, sex, and reproductive planning, as well as cost and access to care.

Conclusions and Relevance

Anxiety disorders affect approximately 34% of adults during their lifetime in the US and are associated with significant distress and impairment. First-line treatments for anxiety disorders include cognitive behavioral therapy, SSRIs such as sertraline, and SNRIs such as venlafaxine extended release.

Improving perinatal depression screening and management: results from a federally qualified health center

INTRODUCTION

Perinatal depression affects 8.5-20% of women. In a systematic review 22% of women with a positive depression screen use mental health services. The objective of this study was to examine the effectiveness of on-site management in the perinatal setting and barriers to care.

METHODS

This is a retrospective chart review of 1042 women who received perinatal care between 1 January to 31 December 2019. Primary outcome was percentage of patients who were assessed after a positive depression screen. The secondary outcome was to determine factors affecting patients' receptiveness to assessment/treatment.

RESULTS

9.52% of women screened positive. Sixty-two (63.9%) met with an on-site social worker for assessment, 6 (6.2%) misunderstood the screening questions, and 33 (34.0%) met criteria for depression. Of those, 9 (27.3%) attended at least one follow-up, 8 (24.2%) were referred to or already in care, 7 (21.2%) no-showed, and 9 (27.3%) declined further care. English speaking patients were more likely to meet with a social worker for diagnostic assessment (69.9% versus 45.8%, P = 0.033).

CONCLUSION

On-site management of a positive depression screen yielded a follow-up rate of 64% versus 49% in other studies. Non-English language may be a barrier to accessing mental health car.

Combining the GP's assessment and the PHQ-9 questionnaire leads to more reliable and clinically relevant diagnoses in primary care

Background

Screening questionnaires are not sufficient to improve diagnostic quality of depression in primary care. The additional consideration of the general practitioner’s (GP’s) assessment could improve the accuracy of depression diagnosis. The aim of this study was to examine whether the GP rating supports a reliable depression diagnosis indicated by the PHQ-9 over a period of three months.

Methods

We performed a secondary data analysis from a previous study. PHQ-9 scores of primary care patients were collected at the time of recruitment (t1) and during a follow-up 3 months later (t2). At t1 GPs independently made a subjective assessment whether they considered the patient depressive (yes/no). Two corresponding groups with concordant and discordant PHQ-9 and GP ratings at t1 were defined. Reliability of the PHQ-9 results at t1 and t2 was assessed within these groups and within the entire sample by Cohen’s Kappa, Pearson’s correlation coefficient and Bland-Altman plots.

Results

364 consecutive patients from 12 practices in the region of Upper Bavaria/Germany participated in this longitudinal study. 279 patients (76.6%) sent back the questionnaire at t2. Concordance of GP rating and PHQ-9 at t1 led to higher replicability of PHQ-9 results between t1 and t2. The reliability of PHQ-9 was higher in the concordant subgroup (κ = 0.507) compared to the discordant subgroup (κ = 0.211) (p = 0.064). The Bland-Altman Plot showed that the deviation of PHQ-9 scores at t1 and t2 decreased by about 15% in the concordant subgroup. Pearson’s correlation coefficient between PHQ-9 scores at t1 and t2 increased significantly if the GP rating was concordant with the PHQ-9 at t1 (r = 0.671) compared to the discordant subgroup (r = 0.462) (p = 0.044).

Conclusions

The combination of PHQ-9 and GP rating might improve diagnostic decision making regarding depression in general practices. PHQ-9 positive results might be more reliable and accurate, when a concordant GP rating is considered.

Depression in non-alcoholic fatty liver disease is associated with an increased risk of complications and mortality

Background and aims

The global prevalence of non-alcoholic fatty liver disease (NAFLD) is expected to rise continuously. Furthermore, emerging evidence has also shown the potential for concomitant depression in NAFLD. This study aims to examine the prevalence, risk factors, and adverse events of depression in NAFLD and evaluate whether treated depression can reverse the increased risks of adverse outcomes.

Materials and methods

This study analyses the 2000–2018 cycles of NHANES that examined liver steatosis with fatty liver index (FLI). The relationship between NAFLD and depression was assessed with a generalized linear mix model and a sensitivity analysis was conducted in the no depression, treated depression, and untreated depression groups. Survival analysis was conducted with cox regression and fine gray sub-distribution model.

Results

A total of 21,414 patients were included and 6,726 were diagnosed with NAFLD. The risk of depression in NAFLD was 12% higher compared to non-NAFLD individuals (RR: 1.12, CI: 1.00–1.26, p = 0.04). NAFLD individuals with depression were more likely to be older, females, Hispanics or Caucasians, diabetic, and have higher BMI. Individuals with depression have high risk for cardiovascular diseases (CVD) (RR: 1.40, CI: 1.25–1.58, p < 0.01), stroke (RR: 1.71, CI: 1.27–2.23, p < 0.01), all-cause mortality (HR: 1.50, CI: 1.25–1.81, p < 0.01), and cancer-related mortality (SHR: 1.43, CI: 1.14–1.80, p = 0.002) compared to NAFLD individuals without depression. The risk of CVD, stroke, all-cause mortality, and cancer-related mortality in NAFLD individuals with treated depression and depression with untreated treatment was higher compared to individuals without depression.

Conclusion

This study shows that concomitant depression in NAFLD patients can increase the risk of adverse outcomes. Early screening of depression in high-risk individuals should be encouraged to improve the wellbeing of NAFLD patients.

Standardized Versus Tailored Implementation of Measurement-Based Care for Depression in Community Mental Health Clinics

Objective

Measurement-based care (MBC) is an evidence-based practice that is rarely integrated into psychotherapy. The authors sought to determine whether tailored MBC implementation can improve clinician fidelity and depression outcomes compared with standardized implementation.

Methods

This cluster-randomized trial enrolled 12 community behavioral health clinics to receive 5 months of implementation support. Clinics randomized to the standardized implementation received electronic health record data captured with the nine-item Patient Health Questionnaire (PHQ-9), a needs assessment, clinical training, guidelines, and group consultation in MBC fidelity. Tailored implementation support included these strategies, but the training content was tailored to clinics’ barriers to MBC, and group consultation centered on overcoming these barriers. Clinicians (N=83, tailored; N=71, standardized) delivering individual psychotherapy to 4,025 adults participated. Adult patients (N=87, tailored; N=141, standardized) contributed data for depression outcome analyses.

Results

The odds of PHQ-9 completion were lower in the tailored group at baseline (odds ratio [OR]=0.28, 95% CI=0.08–0.96) but greater at 5 months (OR=3.39, 95% CI=1.00–11.48). The two implementation groups did not differ in full MBC fidelity. PHQ-9 scores decreased significantly from baseline (mean±SD=17.6±4.4) to 12 weeks (mean=12.6±5.9) (p<0.001), but neither implementation group nor MBC fidelity significantly predicted PHQ-9 scores at week 12.

Conclusions

Tailored MBC implementation outperformed standardized implementation with respect to PHQ-9 completion, but discussion of PHQ-9 scores in clinician-patient sessions remained suboptimal. MBC fidelity did not predict week-12 depression severity. MBC can critically inform collaborative adjustments to session or treatment plans, but more strategic system-level implementation support or longer implementation periods may be needed.

Implementation Science of Telepsychotherapy for Anxiety, Depression, and Somatization in Health Care Workers Dealing with COVID-19

Introduction: Cognitive behavioral therapy (CBT) has proven to be effective in treating affective and somatic symptoms, which are among the leading mental health problems of health care workers (HCWs) dealing with COVID-19 (HCW-COVID-19). However, efforts to develop and evaluate the strategies required to promote its implementation in clinical practice are still scarce, particularly in low- and middle-income countries. Objective: To describe and evaluate the implementation process and clinical impact of a brief, remote, manualized CBT-based intervention for moderate anxiety, depressive, and somatic symptoms among Mexican HCW-COVID-19 ≥18 years old. Methods: The implementation process comprises community engagement, intervention systematization and education, leadership engagement, and team-based coaching as main strategies. A total of 26 participants completed self-report measures of symptoms before and after treatment, and a subsample of 21 answered a final questionnaire on the acceptability of the intervention. Therapists registered the techniques used in each case, regardless of whether they were part of the intervention manual. Results: The number of sessions was 4.6 (2.43). The most frequently employed techniques were those included in the intervention manual, especially identifying and modifying maladaptive thoughts, used to treat 70% of HCW-COVID-19. Supplementary techniques were implemented to enhance treatment or meet HCW-COVID-19s special needs (such as workplace issues, insomnia, COVID-19 status, and bereavement). The intervention had a significant effect (delta Cohen's coefficients ≥1), and the majority of HCW-COVID-19 were "totally satisfied" with its contents and considered it "not complex" (95.2% and 76.1%, respectively). Conclusions: Telepsychotherapy for anxiety, depression, and somatization in HCW coping with health emergencies in middle-income countries is a feasible, clinically valuable, and acceptable form of treatment.

Validity and reliability characteristics of the Silhouettes Fatigue Scale in measuring multiple sclerosis-related fatigue in Turkish-speaking adults

BACKGROUND

The purpose of this study is to investigate the reliability and validity as well as the clinical utility of the Silhouettes Fatigue Scale (SFS), a single-item visual scale to assess fatigue, in adult patients with multiple sclerosis (MS).

METHODS

The study included 61 MS patients and 73 matched healthy controls. Demographic data and disease-related variables of all participants were recorded. Then, the SFS, Visual Analogue Scale (VAS)-fatigue, Fatigue Impact Scale (FIS), Fatigue Severity Scale (FSS), and Beck Depression Inventory (BDI) were applied. SFS, VAS-fatigue, and FSS were repeated after one week. Reliability was evaluated with the intra-class correlation coefficient (ICC) and Bland-Altman analysis. Validity was tested by comparison of healthy controls and patients with MS and correlations with other scales. Accuracy and clinical utility were also evaluated.

RESULTS

SFS scores were 4.49 ± 3.11 (mean ± SD) in MS patients and 1.40 ± 1.44 in healthy controls (p < .001). The ICC for SFS was 0.946. The mean difference between test-retest measurements of SFS was -0.04651 (-95% CI, -0.4815-0.38848), and there was no systemic bias. SFS scores were not correlated with the expanded disability status scale, whereas they were poorly correlated with BDI. Correlations ranging from poor to good were calculated between the SFS and other fatigue-related scales. The optimum cut-off score of the SFS scale was four, with a sensitivity of 0.72 and a specificity of 0.84.

CONCLUSION

This study demonstrated that the SFS is a reliable, responsive, and valid scale with acceptable sensitivity and specificity to assess and quantify clinically significant fatigue in MS patients. These findings as well as the brief and understandable nature of the SFS were encouraging that this scale has good clinical utility.
