Diagnostic Criteria For Major Depression Research Articles

A population-based twin study of the symptomatic diagnostic criteria for major depression that occur within versus outside of major depressive episodes.

Are genetic risk factors for current depressive symptoms good proxies for genetic risk factors for syndromal major depression (MD)? In over 9000 twins from the population-based Virginia Adult Twin Study of Psychiatric and Substance Use Disorders, the occurrence of all nine DSM symptomatic criteria for MD in the last year was assessed at personal interview and then grouped by their temporal co-occurrence. The DSM criteria which occurred outside (OUT) v. inside of (IN) MD episodes were then separated. We calculated tetrachoric correlations for OUT and IN depressive criteria in monozygotic (MZ) and dizygotic (DZ) pairs and fitted univariate and bivariate ACE twin models using OpenMx. The mean twin correlations (±95% CIs) for IN depressive criteria were substantially higher than for OUT depressive criteria in both MZ [+0.35 (0.32-0.38) v. 0.20 (0.17-0.24)] and DZ pairs [0.20 (0.17-0.24) v. 0.10 (0.04-0.16]. The mean IN-OUT cross-correlation in MZ and DZ pairs was modest [+0.15 (0.07-0.24) and +0.07 (0.03-0.12)]. The mean heritability estimates for the nine In v. Out depressive criteria was 0.31 (0.22-0.41) and 0.15 (0.08-0.21), in MZ and DZ pairs, respectively. The mean genetic correlation between the nine IN and OUT depressive criteria was +0.07 (-0.07 to 0.21). Depressive criteria occurring outside depressive episodes are less heritable than those occurring within. These two ways criteria can manifest are not closely genetically related. Current depressive symptoms - most of which are occurring outside of depressive episodes - are not, for genetic studies, good proxies for MD.

Post-awakening salivary alpha-amylase as modulator of treatment response in patients with burnout and major depression

Around 50% of patients with major depression do not respond to standard first-line treatments, such as psychotherapy and pharmacotherapy. At the same time, a subgroup exhibits altered functioning of stress-responsive bodily systems, such as the central locus coeruleus/sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis. Given that these systems impact arousal and cognition, it is possible that this subgroup contributes to the high rates of non-responders. Our aim was to investigate whether sympathetic and HPA axis activity modulate treatment outcomes in patients with stress-related major depression. A total of N = 74 inpatients (median age: 50, 62% male) with signs of burnout who fulfilled diagnostic criteria for major depression were recruited. Saliva samples were collected at awakening as well as 30 and 45 min later. Alpha-amylase activity and cortisol concentrations were determined before patients underwent evidence-based multimodal treatment. Non-responders were defined as patients exhibiting a <50% decrease in depression on the Beck Depression Inventory. Non-responders had significantly higher post-awakening alpha-amylase activity than responders (p = .025). In addition, alpha-amylase activity increased significantly over the course of treatment (p = .004), irrespective of responder status. Post-awakening cortisol was neither a predictor nor an indicator of treatment response. If future research confirms alpha-amylase activity as a modulator of treatment response, this may indicate a subgroup of patients with major depression which may benefit from augmentative treatments, such as heart rate variability biofeedback and/or cognitive interventions targeting high arousal.

Accuracy in recognising happy facial expressions is associated with antidepressant response to a NOP receptor antagonist but not placebo treatment.

Clinical trials with putative antidepressants can be difficult to execute as it can take up to 8 weeks before differences emerge between drug and placebo, and long expensive trials often fail. Implementation of early response biomarkers could aid this process significantly with potential to identify new treatments. In a secondary analysis, we examined the association of early effects on emotional processing with later clinical outcome following treatment with the novel NOP antagonist LY2940094 versus placebo. We hypothesised that early induction of positive bias would be associated with reduced severity of depression after 8 weeks of treatment. This was a multicentre, randomised, double-blind, parallel-group, fixed-dose, placebo-controlled, 8 week study to assess sensitivity of the facial emotional recognition task (FERT) to early changes in emotional bias induced by LY2940094. Patients who met diagnostic criteria for major depression were randomised to receive LY2940094 (N = 70) or placebo (N = 66). At week 1 and 6, the FERT was completed by 33 patients in the LY2940094 group and 34 in the placebo group. Patients identified happy faces with higher accuracy (Wald χ2(1,33) = 14.25, p < 0.001) after 1 week treatment with LY290094 compared to placebo (Wald χ2(1,32) = 0.83, p = 0.36) and this correlated with eventual treatment response measured by the Hamilton Depression Rating Scale 7 weeks later. These data suggest that emotional processing biomarkers may be sensitive to early effects of antidepressant treatment indicative of later clinical response. Further studies in this area may be useful in developing new treatments and clinical trial designs for predicting antidepressant response.

A Meta-analytic Review: Psychological Treatment of Subthreshold Depression in Children and Adolescents

Subthreshold depression has been found to be associated with considerable impairment and an increased risk of developing major depression. Although several randomized trials have examined the effects of psychological interventions for subthreshold depression in children and adolescents, no meta-analysis has integrated the results of these trials. We searched 4 bibliographic databases and included randomized trials comparing psychological interventions with control conditions in children and adolescents scoring above a cut-off of a depression questionnaire but not meeting diagnostic criteria for major depression (or persistent depressive disorder) according to a diagnostic interview. Effect sizes and incidence rates of major depression were pooled with random effects meta-analyses. A total of 12 trials with 1,576 children and adolescents met inclusion criteria. The overall effect size indicating the difference between treatment and control at post-test was g= 0.38 (95% CI= 0.14-0.63), which corresponds to a number-needed-to-treat (NNT) of 8.4. Heterogeneity was moderate to high (I2= 61; 95% CI= 28-79), and there was significant risk of publication bias (p< .04). The 2 studies in children less than 12 years of age showed nonsignificant effects (g= 0.01; 95% CI= -1.16 to 1.18). We found no significant effect on the incidence of major depression at follow-up (relative risk= 0.52; 95% CI= 0.25-1.08), although this may be related to low statistical power. Interventions for subthreshold depression may have positive acute effects in adolescents. There is currently insufficient evidence, however, that these interventions are effective in children less than 12 years of age, or that they prevent the onset of major depression at follow-up.

Influence of established and subjectively perceived as well as evaluated individual characteristics on the utilization of mental health services among individuals with depressive disorders: protocol of a longitudinal study examining how to supplement the \u201cbehavioral model of health services use\u201d and on need-congruent use of mental health services

BackgroundApproximately one out of every three people in Germany who meets the diagnostic criteria for major depression has contact with mental health services. Therefore, according to treatment guidelines, two thirds of all individuals with depression are insufficiently treated. In the past, the subjective perspective of people who (do not) make use of mental health services has been neglected. Factors related to the use of health services are described in Andersen’s Behavioral Model of Health Services Use (ABM). The aim of this study is to supplement operationalizations of subjectively perceived and evaluated individual characteristics in the ABM and to evaluate whether the supplemented model can better explain mental health services use in individuals with depression than established operationalizations.MethodsA representative telephone study with two measurement points will be conducted. In an explanatory mixed-methods design, qualitative interviews will be added to further interpret the quantitative data. A nationwide sample scoring 5 or more on the Patient Health Questionnaire (PHQ-9) will be recruited and interviewed via telephone at T0 and 12 months later (T1). Data on established and subjective characteristics as well as mental health service use will be collected. At T1, conducting a diagnostic interview (Composite International Diagnostic Interview, DIA-X-12/M-CIDI) enables the recording of 12-month diagnoses according to DSM-IV-TR criteria. Ideally, n = 768 datasets will be available and analyzed descriptively by means of regression analysis. Up to n = 32 persons who use or do not use depression-specific health services incongruent with their objective or subjective needs will be interviewed (face-to-face) to better explain their behavior. In addition, theories of non-need-based mental health service use are developed within the framework of the grounded theory-based analysis of the qualitative interviews.DiscussionThe study intends to contribute to the theoretical foundation of health services research and to specify the characteristics described in the ABM. Thus, after completion of the study, a further sophisticated and empirically tested model will be available to explain mental health services. The identified modifiable influencing factors are relevant for the development of strategies to increase mental health service use in line with the objective and subjective needs of individuals with depression.

A randomized controlled trial of Internet-delivered CBT and attention bias modification for early intervention of depression

The conceptualization and empirical knowledge base related to major depression has increased dramatically in recent years. We now have well-developed and validated models of depression from a range of theoretical perspectives. These models have significantly enhanced the development of effective treatments and preventative interventions. Although various prevention programs are available, Web-based protocols can enhance accessibility to evidence-based prevention programs. The current study involved a randomized controlled trial focused on the prevention and treatment of depression in high-risk first- and second-year undergraduate students. Three Internet-delivered preventative programs were compared: cognitive behavioral therapy (CBT; MoodGym), attentional bias modification, and an active attentional control condition. Participants ( n = 350) completed symptom measurement pre- and post-intervention (6 weeks) and again at a 4-month follow-up, when they were also administered a structured diagnostic interview. Participants in the CBT condition showed more dramatic and continuous depressive symptom improvement between baseline and follow-up than did participants in the other two conditions. In addition, significantly fewer individuals in CBT condition met diagnostic criteria for major depression at follow-up than in the other conditions. These findings have important implications for future early intervention research and practice.

Major Depression in Chinese Medicine Outpatients with Stagnation Syndrome: Prevalence and the Impairments in Well-Being.

Stagnation syndrome, a diagnostic entity in traditional Chinese medicine (TCM), has been long regarded as the TCM counterpart of major depression in Western medicine. The study investigated the prevalence of major depression among stagnation syndrome patients and evaluated their well-being and functioning outcomes. In total, 117 patients diagnosed with stagnation syndrome were measured using Stagnation Scale, the Patient Health Questionnaire-9 (PHQ-9), and the Body-Mind-Spirit Well-Being Inventory. Results indicate major depression among stagnation syndrome patients was characterized by a high co-occurrence rate and worse physical, mental, and functional outcomes. More than one-quarter (26.5%) of the patients met the DSM-V diagnostic criteria for major depression and over half (53%) exceeded the PHQ-9 cutoff (score above 10) for moderate/severe depression symptoms. The wellness of the stagnation syndrome patients was worse (M = 298.2, SD = 66.5) than that of the general population (M = 360.9, SD = 79.9), with a large Cohen's d value of 0.9. The “wellness outlook” of the depressed stagnation syndrome patients appeared grimmer (M = 252.3, SD = 52.2). The correlation between stagnation and depression was higher for affective symptoms than somatic symptoms. Physical distress did not mediate the relationship between stagnation and daily functioning. These might suggest that stagnation syndrome and major depression may share some similar psychological mechanisms.

Prevalence of and risk factors for minor and major depression among community-dwelling older adults in Taiwan.

This study was conducted to estimate prevalence rates and risk factors for late-life depression in a large nationwide representative sample from Taiwan. A total of 5,664, randomly sampled individuals aged ≥55 years were enrolled. Clinically, relevant depressive symptoms were classified using the Center for Epidemiological Studies Depression Scale (CES-D score ≥16), and major depression was confirmed using the Primary Care Evaluation of Mental Disorders. Individuals with clinically relevant depressive symptoms, who did not meet the strict diagnostic criteria for major depression, were considered to have minor depression. Multinomial logistic regression analyses were conducted to identify risk factors for major and minor depression, including socio-demographic characteristics, medical conditions, lifestyle behaviors, social support network, and life events. The prevalence rates of minor and major depression were 3.7% and 1.5%, respectively. Major depression was associated with personal vulnerability factors, such as poor social support, cognitive impairment, comorbid pain conditions, and sleep disturbance. However, minor depression was more likely to be related to adverse life events, including increased burden on families, changes in health status, or relationship problem. Approximately, 20.0% of individuals with major depression received antidepressant treatment. Late-life depression was less prevalent among community-dwelling older adults in Taiwan than among populations in other countries. Our findings may aid the early detection and treatment of late-life depression and provide a basis for future investigations.

A parallel group randomised open blinded evaluation of Acceptance and Commitment Therapy for depression after psychosis: Pilot trial outcomes (ADAPT)

BackgroundDepression is one of the major contributors to poorer quality of life amongst individuals with psychosis and schizophrenia. The study was designed as a Pilot Trial to determine the parameters of a larger, definitive pragmatic multi-centre randomised controlled trial of Acceptance and Commitment Therapy for depression after psychosis (ACTdp) for individuals with a diagnosis of schizophrenia who also meet diagnostic criteria for major depression. MethodsParticipants were required to meet criteria for schizophrenia and major depression. Blinded follow-ups were undertaken at 5-months (end of treatment) and at 10-months (5-months posttreatment). Primary outcomes were depression as measured by the Calgary Depression Scale for Schizophrenia (CDSS) and the Beck Depression Inventory (BDI). ResultsA total of 29 participants were randomised to ACTdp + Standard Care (SC) (n=15) or SC alone (n=14). We did not observe significant differences between groups on the CDSS total score at 5-months (Coeff=−1.43, 95%CI −5.17, 2.32, p=0.45) or at 10-months (Coeff=1.8, 95%CI −2.10, 5.69, p=0.36). In terms of BDI, we noted a statistically significant effect in favour of ACTdp+SC at 5-months (Coeff=−8.38, 95%CI −15.49, −1.27, p=0.02) but not at 10-months (Coeff=−4.85, 95%CI −12.10, 2.39, p=0.18). We also observed significant effects on psychological flexibility at 5-months (Coeff=−8.83, 95%CI −14.94, −2.71, p<0.01) but not 10-months (Coeff=−4.92, 95%CI −11.09, 1.25, p=0.11). ImplicationsIn this first RCT of a psychological therapy with depression as the primary outcome, ACT is a promising intervention for depression in the context of psychosis. A further large-scale definitive randomised controlled trial is required to determine effectiveness.Trial registration: ISRCTN: 33306437

Suicidality in primary care patients who present with sadness and anhedonia: a prospective European study.

BackgroundSadness and anhedonia (loss of interest in activities) are central symptoms of major depression. However, not all people with these symptoms meet diagnostic criteria for major depression. We aimed to assess the importance of suicidality in the outcomes for primary care patients who present with sadness and anhedonia.MethodCohort study of 2,599 unselected primary care attenders in six European countries followed up at 6 and 12 months.Results1) In patients with sadness and/or anhedonia who were not depressed at entry to the study, suicide plans (OR = 3.05; 95 % CI = 1.50–6.24; p = 0.0022) and suicide attempts (OR = 9.08; 95 % CI = 2.57–32.03; p = 0.0006) were significant predictors of developing new onset depression at 6 or 12 months. 2) In patients with sadness and/or anhedonia who met CIDI criteria for major depression at entry, suicidal ideation (OR = 2.93; 95 % CI = 1.70–5.07; p = 0.0001), suicide plans (OR = 3.70; 95 % CI = 2.08–6.57; p < 0.0001), and suicide attempts (OR = 3.33; 95 % CI = 1.47–7.54; p = 0.0040) were significant predictors of persistent depression at 6 or 12 months.ConclusionsThree questions on suicidality could help primary care professionals to assess such patients more closely without necessarily establishing whether they meet criteria for major depression.

A meta-analysis of chemokines in major depression

Chemokines are increasingly recognised as playing a role in depression. Here we meta-analyse the data on concentrations of all chemokines in patients diagnosed with a major depression versus healthy controls. We included studies which utilised Diagnostic and Statistical Manual (DSM)-IV diagnostic criteria for major depression, participants free from major medical conditions, studies with healthy controls, and unstimulated measurements of chemokines. We only included chemokines which had ≥3 studies performed. Two chemokines and 15 studies in total met criteria for this meta-analysis; 8 for Monocyte Chemotactic Protein (MCP)-1/CCL2 (n=747), and 7 for Interleukin (IL)-8/CXCL8 (n=560). There were significantly higher concentrations of CCL2/MCP-1 in depressed subjects compared with control subjects – overall mean difference of 36.43pg/mL (95% CI: 2.43 to 70.42). There was significant heterogeneity across these studies (I2=98.5%). The estimates of mean difference between the control and depression groups did not remain significant when the trim-and-fill procedure was used to correct for publication bias. There was no significant difference in concentrations of IL-8/CXCL8 in depressed subjects compared with control subjects. Significant heterogeneity was found across these studies (I2=96.7%). The estimates of mean difference between the control and depression groups remained non-significant when the trim-and-fill procedure was used to correct for publication bias. This meta-analysis reports significantly heterogeneity in this field among studies. There are higher concentrations of the chemokine MCP-1/CCL2 in depressed subjects compared with control subjects, and no differences for IL-8/CXCL8. More high quality research and consistent methodologies are needed in this important area of enquiry.

Are Antidepressants Overprescribed for Mild-to-Moderate Depression?

Concerns about overprescription of antidepressants have been based on high rates of use in patients who retrospectively self-reported that they did not meet diagnostic criteria for major depression. Yet, some of these patients might not have remembered the severity of their depression, which might have been successfully treated with antidepressants. Now, researchers prospectively examine clinician-rated depression on the 9-item Patient …

The DSM-5 and the Continuing Transformation of Normal Sadness Into Depressive Disorder

For millennia, diagnosticians distinguished natural sadness that arose from social circumstances from depressive disorders that were disproportionate to their contexts. In 1980, the DSM-III transformed this tradition through equating depressive disorders with symptoms without regard to context. Nevertheless, it excluded grieving people without especially severe or enduring symptoms from diagnosis. Subsequently, considerable empirical research indicated that bereavement was not unique but a model for all stressor-maintained conditions. Yet, despite the evidence showing that the causes, prognoses, and optimal treatments for context-specific depressions differ from those that aren’t, the DSM-5 removed the bereavement exclusion from the diagnostic criteria for major depression. This article considers the reasons behind this elimination and its implications for the research, labeling, and treatment of depression.

The similarity of the structure of DSM-IV criteria for major depression in depressed women from China, the United States and Europe.

Do DSM-IV diagnostic criteria for major depression (MD) in Chinese and Western women perform in a similar manner? The CONVERGE study included interview-based assessments of women of Han Chinese descent with treated recurrent MD. Using Mplus software, we investigated the overall degree of between-sample measurement invariance (MI) for DSM-IV diagnostic criteria for MD in the CONVERGE sample and samples selected from four major Western studies from the USA and Europe matched to the inclusion criteria of CONVERGE. These analyses were performed one pair at a time. We then compared the results from CONVERGE paired with Western samples to those obtained when examining levels of MI between pairs of the Western samples. Assuming a single factor model for the nine diagnostic criteria for MD, the level of MI based on global fit indexes observed between the CONVERGE and the four Western samples was very similar to that seen between the Western samples. Comparable results were obtained when using a two-factor structure for MI testing when applied to the 14 diagnostic criteria for MD disaggregated for weight, appetite, sleep, and psychomotor changes. Despite differences in language, ethnicity and culture, DSM criteria for MD perform similarly in Chinese women with recurrent MD and comparable subjects from the USA and Europe. The DSM criteria for MD may assess depressive symptoms that are relatively insensitive to cultural and ethnic differences. These results support efforts to compare findings from depressed patients in China and Western countries.

Positive imagery cognitive bias modification (CBM) and internet-based cognitive behavioral therapy (iCBT): A randomized controlled trial

BackgroundAccruing evidence suggests that positive imagery-based cognitive bias modification (CBM) could have potential as a standalone targeted intervention for depressive symptoms or as an adjunct to existing treatments. We sought to establish the benefit of this form of CBM when delivered prior to Internet cognitive behavioral therapy (iCBT) for depression MethodsA randomized controlled trial (RCT) of a 1-week Internet-delivered positive CBM vs. an active control condition for participants (N=75, 69% female, mean age=42) meeting diagnostic criteria for major depression; followed by a 10-week iCBT program for both groups. ResultsModified intent-to-treat marginal and mixed effect models demonstrated no significant difference between conditions following the CBM intervention or the iCBT program. In both conditions there were significant reductions (Cohen׳s d .57–1.58, 95% CI=.12–2.07) in primary measures of depression and interpretation bias (PHQ9, BDI-II, AST-D). Large effect size reductions (Cohen׳s d .81–1.32, 95% CI=.31–1.79) were observed for secondary measures of distress, disability, anxiety and repetitive negative thinking (K10, WHODAS, STAI, RTQ). Per protocol analyses conducted in the sample of participants who completed all seven sessions of CBM indicated between-group superiority of the positive over control group on depression symptoms (PHQ9, BDI-II) and psychological distress (K10) following CBM (Hedges g .55–.88, 95% CI=−.03–1.46) and following iCBT (PHQ9, K10). The majority (>70%) no longer met diagnostic criteria for depression at 3-month follow-up. LimitationsThe control condition contained many active components and therefore may have represented a smaller ‘dose’ of the positive condition. ConclusionsResults provide preliminary support for the successful integration of imagery-based CBM into an existing Internet-based treatment for depression.

Diagnostic criteria for depression in type 2 diabetes: a data-driven approach.

BackgroundWhile depression is a frequent psychiatric comorbid condition in diabetes and has significant clinical impact, the syndromal profile of depression and anxiety symptoms has not been examined in detail.AimsTo determine the syndromal pattern of the depression and anxiety spectrum in a large series of patients with type 2 diabetes, as determined using a data-driven approach based on latent class analysis (LCA).MethodType 2 diabetes participants from the observational community-based Fremantle Diabetes Study Phase II underwent assessment of lifetime depression using the Brief Lifetime Depression Scale, the Patient Health Questionnaire 9-item version (PHQ-9) for current depression symptoms, and the Generalized Anxiety Disorder Scale that was specifically developed and validated for this study. The main outcome measure was classes of patients with a specific syndromal profile of depression and anxiety symptoms based on LCA.ResultsLCA identified four classes that were interpreted as “major anxious depression”, “minor anxious depression”, “subclinical anxiety”, and “no anxious depression”. All nine DSM-IV/5 diagnostic criteria for major depression identified a class with a high frequency of major depression. All symptoms of anxiety had similar high probabilities as symptoms of depression for the “major depression-anxiety” class. There were significant differences between classes in terms of history of depression and anxiety, use of psychoactive medication, and diabetes-related variables.ConclusionsPatients with type 2 diabetes show specific profiles of depression and anxiety. Anxiety symptoms are an integral part of major depression in type 2 diabetes. The different classes identified here provide empirically validated phenotypes for future research.

Psychiatric disorders, suicidality, and personality among young men by sexual orientation.

Personality and its potential role in mediating risk of psychiatric disorders and suicidality are assessed by sexual orientation, using data collected among young Swiss men (n=5875) recruited while presenting for mandatory military conscription. Mental health outcomes were analyzed by sexual attraction using logistic regression, controlling for five-factor model personality traits and socio-demographics. Homo/bisexual men demonstrated the highest scores for neuroticism-anxiety but the lowest for sociability and sensation seeking, with no differences for aggression-hostility. Among homo/bisexual men, 10.2% fulfilled diagnostic criteria for major depression in the past 2weeks, 10.8% for ADHD in the past 12months, 13.8% for lifetime anti-social personality disorder (ASPD), and 6.0% attempted suicide in the past 12months. Upon adjusting (AOR) for personality traits, their odds ratios (OR) for major depression (OR=4.78, 95% CI 2.81-8.14; AOR=1.46, 95% CI 0.80-2.65) and ADHD (OR=2.17, 95% CI=1.31-3.58; AOR=1.00, 95% CI 0.58-1.75) lost statistical significance, and the odds ratio for suicide attempt was halved (OR=5.10, 95% CI 2.57-10.1; AOR=2.42, 95% CI 1.16-5.02). There are noteworthy differences in personality traits by sexual orientation, and much of the increased mental morbidity appears to be accounted for by such underlying differences, with important implications for etiology and treatment.

Validation of Gujarati version of 15-item Geriatric Depression scale in elderly medical outpatients of General hospital in Gujarat

Background: Depressive disorders are a public health problem in developing countries. Access to valid and reliable screening tool is needed to identify geriatric depression. Aims & Objectives: To validate Gujarati version of geriatric depression scale -15 (GDS-15) as a screening instrument to identify geriatric Depression in elderly medical patients. Materials and Methods: This is a hospital based cross -sectional study. 200 Gujarati elderly patients (>65 years) attending the medical out patients department, unaware about their mental health status, were selected and Gujarati GDS-15 was administered. Then all patients were interviewed by a psychiatrist (blind to their GDS-15 scores). DSM-IV diagnostic criteria for major depression were used. Various thresholds of the GDS-15 were compared against the standards of the DSM-IV. A Receiver operator characteristic curve was drawn to obtain the best threshold value. Internal reliability of GDS-15 was assessed using Cronbach’s alpha reliability coefficients. Results: 33.5% (67/200) elderly patients satisfied DSM-IV diagnostic criteria for Major Depression. The optimal threshold for the GDS-15 was 7.5 with a sensitivity of 86.6% and a specificity of 73.3%. The area under the curve was 0.877. Cronbach’s alpha of the total scores was 0.806. Conclusion: The Gujarati GDS-15 has good properties as screening instruments for major depression in Gujarati elderly medical patients, as presented in our findings.
