Psychometric Properties of Bangla Young Mania Rating Scale
The Malaysian Journal of Psychiatry, 2019
Introduction: The Young Mania Rating Scale (YMRS) is widely used clinician-rated instrument which measures the symptom severity of mania and considered as ʺgold standardʺ. We aimed to assess the psychometric properties of Bangla YMRS. Methods: Current validation study was performed from January 2015 to September 2016 among patients of mania of department of psychiatry of Bangabandhu Sheikh Mujib Medical University, Dhaka. The adaptation of YMRS to Bangla was achieved according to the standard process of forward-backward translation. Data were collected from 51 manic patients and analyzed different forms of reliability and validity by Statistical Package for the Social Science version 16.0 software. Results: The Cronbach's alpha value was 0.89 and interrater reliability was measured by Cohen kappa coefficient and ranged from 0.80 to 0.98 those signifies an acceptable reliability statistic. Face validity and content validity were assessed systematically and construct validity was ...
Comparative evaluation of two self-report mania rating scales
Biological Psychiatry, 1996
Inventory (SRMI), have been shown to reliably diagnose mania. In the current study we further evaluated the utility of these scales relative to each other and to the observer-rated Young Mania Rating Scale (YMRS), for quantifying the severity of manic/hypomanic symptoms cross-sectionally and over time, in 20 patients with rapid-cycling bipolar disorder. The self-report scales correlated well with each other and with the YMRS, but each covered a somewhat different domain of the manic syndrome. The SRMI and the ISS were more sensitive than the YMRS to the mood fluctuations in the euthymic to hypomanic range observed in our subjects. Used in tandem, the two self-report scales may find application in clinical research with outpatients with bipolar disorder, and as an adjunct to clinical monitoring in this patient population.
Objective: According to DSM-5, bipolar disorder is a condition in which the patient experiences one or several manic episodes and sometimes major depressive episodes too. The signs and symptoms of the disorders in DSM are generally influenced by cultural and ethnic factors. Therefore, the present study was aimed at identifying the clinical manifestations of mania in bipolar I disorder in Iranian population. Methods: The present work is a cross-sectional study. The participants included 64 patients in the manic phase of bipolar I disorder who were selected from the Razi psychiatric hospital and the Taleghani Hospital, using a convenience sampling method. The study data were gathered using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and the Young Mania Rating Scale (YMRS). Results: According to the findings, the most common signs and symptoms of mania in hospitalized patients with bipolar I disorder included reduced need for sleep (89.1), poor insight (87.5), elevated mood (85.9), talkativeness (79.7), and psychotic features (68.8). The major symptoms of the patients according to DSM-5 criteria included reduced need for sleep (89.1), talkativeness (79.7), and psychomotor agitation (40.6). According to t-test analysis, patients with and without a history of mental disorders did not have significantly different mania scores. The one-way analysis of variance (ANOVA) analysis indicated no significant difference in mania scores based on the age of onset of the disorder, marital status (single, married, divorced, or widow), education level, and number of hospitalizations. The chi-squared test revealed that patients with a lower education level showed more aggressive behaviors. Conclusion: According to our results, since the response of a patient to a particular treatment is largely influenced by the symptoms of the disorder, clinicians should pay critical attention to the most common signs and symptoms of any mania.

Toward an integration of parent and clinician report on the Young Mania Rating Scale
Journal of Affective Disorders, 2003
Background: The Young Mania Rating Scale (YMRS) has validity in the assessment of mania in adults. The purpose of this study was to examine how the YMRS might optimally be used in the assessment of youths. Methods: Children and adolescents between the ages of 5 and 17 years of age participated in this study. All youths were evaluated with the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). Based on the K-SADS results, subjects were then assigned to one of five groups: a bipolar I group, another bipolar spectrum group, a depressive disorders group, a disruptive behaviors disorders group, and a no diagnosis group. Guardians completed a version of the YMRS modified for parent reporting. Clinicians completed the YMRS on all participating youths. Results: Both parent and clinician ratings on the YMRS assigned patients (n = 117) to the appropriate diagnostic group with 71 -98% accuracy. Combining information from multiple informants did not significantly improve diagnostic group assignment. Limitations: The same raters completed the clinician YMRS and the K-SADS interview involving the parent. Findings need replication in an independent sample with lower base rates of bipolar disorder, less rigorously trained and supervised raters, and using a prospective design to provide maximum generalizability of results. Current results should be interpreted as a 'best case' scenario. Conclusions: These data suggest that the YMRS may be a useful adjunct in assessing the severity of mania in youths. Tentative cutting scores are proposed to maximize efficiency, sensitivity, and specificity. D
Reliability and validity of the Bipolar Depression Rating Scale on an Iranian sample
Archives of Iranian medicine, 2010
The Bipolar Depression Rating Scale is an instrument to measure depression severity in patients diagnosed with bipolar disorder. This study has reevaluated the psychometric values of the Bipolar Depression Rating Scale through assessing an Iranian sample of patients with bipolar depression. A total of 60 patients (36 males and 24 females) with bipolar depression referred to four medical centers in Tehran, Iran were interviewed with the Structured Clinical Interview for DSM-IV axis I Disorders, Young Mania Rating Scale, center for Epidemiological Studies Depression Scale, and the Bipolar Depression Rating Scale. Internal consistency and inter-rater reliability of the Bipolar Depression Rating Scale, and Pearson's correlation coefficient between the Bipolar Depression Rating Scale and Young Mania Rating Scale/Center for Epidemiological Studies Depression Scale were calculated. The Cronbach's alpha coefficient was 0.81. The Pearson's correlation coefficients of the Bipolar ...
Reliability and validity of a Portuguese version of the Young Mania Rating Scale
Brazilian Journal of Medical and Biological Research, 2005
The reliability and validity of a Portuguese version of the Young Mania Rating Scale were evaluated. The original scale was translated into and adapted to Portuguese by the authors. Definitions of clinical manifestations, a semi-structured anchored interview and more explicit rating criteria were added to the scale. Fifty-five adult subjects, aged 18 to 60 years, with a diagnosis of Current Manic Episode according to DSM-III-R criteria were assessed using the Young Mania Rating Scale as well as the Brief Psychiatric Rating Scale in two sessions held at intervals from 7 to 10 days. Good reliability ratings were obtained, with intra-class correlation coefficient of 0.97 for total scores, and levels of agreement above 0.80 (P < 0.001) for all individual items. Internal consistency analysis resulted in an α = 0.67 for the scale as a whole, and an α = 0.72 for each standardized item (P < 0.001). For the concurrent validity, a correlation of 0.78 was obtained by the Pearson coefficient between the total scores of the Young Mania Rating Scale and Brief Psychiatric Rating Scale. The results are similar to those reported for the English version, indicating that the Portuguese version of the scale constitutes a reliable and valid instrument for the assessment of manic patients.

Background-Factor analysis has been used to identify potential clinical subtypes of mania in pediatric bipolar disorder. Results vary in the number of factors retained. The present study used a formal diagnostic instrument to examine how symptoms of mania in young people are expressed, depending on age of symptom onset and current age. Methods-Trained clinicians completed the Schedule of Affective Disorders and Schizophrenia for School-Age Children (K-SADS) Mania Rating Scale (MRS) with parents of 163 children with child-onset of symptoms (before age 12), 94 adolescents with child-onset of symptoms, and 90 adolescents with adolescent-onset of symptoms (after age 12). Factor analysis of symptom ratings during the most severe lifetime manic episode was performed for each age group. Results-Symptom factor structures were established for each age group. Two factors were evident for children with child-onset of symptoms ("activated/pleasure seeking" and "labile/ disorganized"), one factor was present for adolescents with child-onset of symptoms ("activated/ pleasure seeking/disorganized") and two factors were evident for adolescents with adolescentonset of symptoms ("activated/pleasure seeking" and "disorganized/psychotic"). The factor
Development of the Bipolar Inventory of Symptoms Scale
Acta Psychiatrica Scandinavica, 2007
Objective: Most rating scales for bipolar disorders (BDs) do not encompass the spectrum of symptomatology now established as characterizing the illness. We report the rationale, format, reliability and initial validity studies of the Bipolar Inventory of Symptoms Scale (BISS), a 44-item scale designed to encompass the spectrum of behavioral disturbances in BDs. Method: Structured video interviews of 20 patients representing four bipolar syndromal subtypes were rated by nine raters. Results: Generally, high inter-rater reliability and internal consistency were established for the depression and mania subscales and the BISS total score. The BISS discriminated across subtypes of bipolar patients with depressed, manic/hypomanic, mixed manic or recovered status. Conclusion: The BISS has adequate reliability, concurrent validity and is capable of discriminating between bipolar subtypes. It also provides a comprehensive scale to assess discrete behavioral components of BD.
