Abstract Background: To assess the reliability and validity of Patient Health Questionnaire-9 (PHQ-9) for patients with major depressive disorder (MDD) and to assess the feasibility of its use in psychiatric hospitals in China. Methods: 109 outpatients or inpatients with MDD who qualified the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria completed PHQ-9 and Hamilton Depression Scale (HAMD-17). Two weeks after the initial evaluation, 54 randomly selected patients underwent repeat assessment using PHQ-9. For validity analysis, the construct validity and criterion validity were assessed. The internal concordance coefficient and the test-retest correlation coefficients were used for reliability analysis. The correlation between total score and scores for each item and the correlation between scores for various items were evaluated using Spearman correlation coefficient. Results: Principal components factor analysis showed good construct validity of the PHQ-9. PHQ-9 total score showed a positive correlation with HAMD-17 total score (r=0.610, P<0.001). With HAMD as the standard, PHQ-9 depression scores of 7, 15, and 21 points were used as cut-offs for mild, moderate, and severe depression, respectively. Consistency assessment was conducted between the depression severity as assessed by PHQ-9 and HAMD (Kappa=0.229, P<0.001). Intraclass correlation coefficient between PHQ-9 total score and HAMD total score was 0.594 (95% confidence interval: 0.456–0.704, P<0.001). The Cronbach's α coefficient of PHQ-9 was 0.892. Correlation coefficients between each item score and the total score ranged from 0.567–0.789 (P<0.01); the correlation coefficient between various item scores ranged from 0.233–0.747. The test-retest correlation coefficient for total score was 0.737. Conclusions: PHQ-9 showed good reliability and validity, and high adaptability for patients with MDD in psychiatric hospital. It is a simple, rapid, effective, and reliable tool for screening and evaluation of the severity of depression.

Mixed Features

During the past two decades, a number of studies have found that depressed patients frequently have manic symptoms intermixed with depressive symptoms. While the frequency of mixed syndromes are more common in bipolar than in unipolar depressives, mixed states are also common in patients with major depressive disorder. The admixture of symptoms may be evident when depressed patients present for treatment, or they may emerge during ongoing treatment. In some patients, treatment with antidepressant medication might precipitate the emergence of mixed states. It would therefore be useful to systematically inquire into the presence of manic/hypomanic symptoms in depressed patients. We can anticipate that increased attention will likely be given to mixed depression because of changes in the DSM–5. In the present article, I review instruments that have been utilized to assess the presence and severity of manic symptoms and therefore could be potentially used to identify the DSM–5 mixed-features specifier in depressed patients and to evaluate the course and outcome of treatment. In choosing which measure to use, clinicians and researchers should consider whether the measure assesses both depression and mania/hypomania, assesses all or only some of the DSM–5 criteria for the mixed-features specifier, or assesses manic/hypomanic symptoms that are not part of the DSM–5 definition. Feasibility, more so than reliability and validity, will likely determine whether these measures are incorporated into routine clinical practice.

OBJECTIVE: The aim of this study was to translate the Structured Clinical Interview for Mood Spectrum into Brazilian Portuguese, measuring its reliability, validity, and defining scores for bipolar disorders. METHOD: Questionnaire was translated (into Brazilian Portuguese) and back-translated into English. Sample consisted of 47 subjects with bipolar disorder, 47 with major depressive disorder, 18 with schizophrenia and 22 controls. Inter-rater reliability was tested in 20 subjects with bipolar disorder and MDD. Internal consistency was measured using the Kuder Richardson formula. Forward stepwise discriminant analysis was performed. Scores were compared between groups; manic (M), depressive (D) and total (T) threshold scores were calculated through receiver operating characteristic (ROC) curves. RESULTS: Kuder Richardson coefficients were between 0.86 and 0.94. Intraclass correlation coefficient was 0.96 (CI 95 % 0.93-0.97). Subjects with bipolar disorder had higher M and T, and similar D scores, when compared to major depressive disorder (ANOVA, p < 0.001). The sub-domains that best discriminated unipolar and bipolar subjects were manic energy and manic mood. M had the best area under the curve (0.909), and values of M equal to or greater than 30 yielded 91.5% sensitivity and 74.5% specificity. CONCLUSION: Structured Clinical Interview for Mood Spectrum has good reliability and validity. Cut-off of 30 best differentiates subjects with bipolar disorder vs. unipolar depression. A cutoff score of 30 or higher in the mania sub-domain is appropriate to help make a distinction between subjects with bipolar disorder and those with unipolar depression.

Background: Efficacy has been proven for vortioxetine in short-term and long-term treatment of major depressive disorder (MDD), with broad beneficial effects on emotional, physical and cognitive symptoms. Limited specific data on the effects of vortioxetine on depression-related physical symptoms have been published. Methods: A meta-analysis was carried out of five short-term multinational, double-blind, placebo-controlled studies. These studies were conducted in a total of 2105 adult MDD outpatients (18–75 years) with a major depressive episode of ⩾3 months’ duration. Only patients treated with a dose of 5 or 10 mg vortioxetine (therapeutic doses) or placebo were included in this analysis. Efficacy assessment of vortioxetine on the physical symptoms of depression included all items of the Hamilton Depression Scale (HAM-D) assessing physical symptoms, and all somatic items in the Hamilton Anxiety Scale (HAM-A). A subgroup analysis in MDD patients with coexisting anxiety symptoms (i.e. those with a HAM-A ⩾20 at baseline) was also performed. Results: A significant improvement ( p<0.05) of vortioxetine versus placebo was observed on all HAM-D items measuring physical symptoms, except for the somatic gastrointestinal symptoms and loss of weight items. Significant effects were also observed on the HAM-A somatic items: general somatic symptoms, gastrointestinal symptoms, and autonomic symptoms. In patients with a high baseline level of anxiety, a significant effect of vortioxetine was also observed on the physical symptoms of depression. Conclusions: These analyses indicate that patients with MDD, including those with a high level of anxiety symptoms, have significant improvements in MDD-associated physical symptoms when treated with vortioxetine.

Abstract Background : Dynamic Interpersonal Psychotherapy (DIT) is a brief manualized depression-focused intervention. This paper describes a study protocol of a multi-site, three-arm randomized controlled trial comparing medication plus DIT to medication alone and medication plus an active control psychotherapy in the treatment of major depressive disorder (MDD). Methods : 240 patients with MDD will be randomly allocated on a 1:1:1 basis to the treatment conditions, with 80 patients in each group. Patients will be assessed pre-and post-intervention and at 6- and 12-months follow-up with the 17-item Hamilton Depression Scale (HAMD-17) and Hamilton Anxiety Scale (HAMA-14) administered by blind evaluators, and the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder-7-item scale(GAD-7), side effect reaction scale (TESS), and The Self-Assessment Scale of the Overall Efficacy and Satisfaction of Patients (SASE). The primary outcome is change from baseline in HAMD-17 scores. Secondary outcomes include rates of response, remission and relapse, change from baseline in self-report depression and measures of anxious symptomatology, and subjective satisfaction of patients. Discussion: This will be the first multicentered RCT in China to assess the potential efficacy of psychotherapy for MDD. The study has the potential to inform clinical treatment guidelines for the treatment of MDD in China.

Background: Recent studies have reported changes in the electroencephalograms (EEG) of patients with major depressive disorder (MDD). However, little research has explored EEG differences between adolescents with MDD and healthy controls, particularly EEG microstates differences. The aim of the current study was to characterize EEG microstate activity in adolescents with MDD and healthy controls (HCs).Methods: A total of 35 adolescents with MDD and 35 HCs were recruited in this study. The depressive symptoms were assessed by Hamilton Depression Scale (HAMD) and Children's Depression Inventory (CDI), and the anxiety symptoms were assessed by Chinese version of DSM-5 Level 2-Anxiety-Child scale. A 64-channel EEG was recorded for 5 min (eye closed, resting-state) and analyzed using microstate analysis. Microstate properties were compared between groups and correlated with patients' depression scores.Results: We found increased occurrence and contribution of microstate B in MDD patients compared to HCs, and decreased occurrence and contribution of microstate D in MDD patients compared to HCs. While no significant correlation between depression severity (HAMD score) and the microstate metrics (occurrence and contribution of microstate B and D) differing between MDD adolescents and HCs was found.Conclusions: Adolescents with MDD showed microstate B and microstate D changes. The obtained results may deepen our understanding of dynamic EEG changes among adolescents with MDD and provide some evidence of changes in brain development in adolescents with MDD.

PURPOSE: The Radboud Dysarthria Assessment (RDA) was published in 2014. Adaptation into a pediatric version (p-RDA) was required because of relevant differences between children and adults. The purpose of this study was to assess the feasibility of the p-RDA and to test intra-rater and inter-rater reliability as well as the validity of the two severity scales (function and activity level). METHODS: Video recordings were made of 35 participants with (suspected) dysarthria (age 4 to 17 years) while being assessed using the p-RDA. Intra-rater reliability was assessed by one, and inter-rater reliability by two experiments using the Intraclass Correlation Coefficient (ICC). Validity of the severity scales was tested by correlating the consensus scores with the independently rated scores on four communication scales, three mobility scales, and one self-care scale using Spearman correlation coefficients (r s). RESULTS: The assessment was applicable for 89% of the tested sample, with good intra-rater and inter-rater reliability (ICC = 0.88–0.98 and 0.83–0.93). The p-RDA severity scales (function and activity level) correlated from substantially to strongly with the communication scales (r s = 0.69–0.82 and 0.77–0.92) and self-care scale (r s = 0.76–0.71) and correlated substantially with the mobility scales (r s = 0.49–0.60). CONCLUSION: The feasibility, reliability and validity of the p-RDA are sufficient for clinical use.

OBJETIVE: Recent literature has highlighted the role of psychotherapy in the treatment of major depressive disorder. Combined therapies comprising both psychotherapy and pharmacotherapy have presented the best results. Although several kinds of psychotherapies have been studied in the treatment of depressive disorders, there remains a lack of data on psychodramatic psychotherapy in the treatment of major depressive disorder. The objective of this study was to evaluate the impact of psychodramatic psychotherapy (in a sample of major depressive disorder patients. METHOD: This is an open, naturalistic, controlled, non-randomized study. Twenty major depressive disorder patients (according to the DSM-IV criteria), under pharmacological treatment for depression, with Hamilton Depression Scale total scores between 7 and 20 (mild to moderate depression), were divided into two groups. Patients in the psychotherapeutic group took part in 4 individual and 24 structured psychodramatic group sessions, whilst subjects in the control group did not participate in this psychodramatic psychotherapy. Both groups were evaluated with the Social Adjustment Scale - Self Report and the Hamilton Depression Scale. RESULTS: Psychotherapeutic group patients showed a significant improvement according to the Social Adjustment Scale - Self Report and the Hamilton Depression Scale scores at endpoint, compared to those of the control group. CONCLUSIONS: Results suggest that individual and group psychodramatic psychotherapy, associated to pharmacological treatment, provides good clinical benefits in the treatment of major depressive disorder.
