Objective: The present study examined the psychometric properties of the Young Mania Rating Scale. Methods: This cross-sectional study included 65 patients with bipolar I disorder in the manic phase and 145 healthy individuals. The patients were selected from the Razi Psychiatric Hospital and Taleghani Hospital, while the controls were selected from the general population of Tehran, using a purposive sampling method. Data were collected using the structured clinical interview for DSM-IV axis I disorders and the Young Mania Rating Scale (YMRS) and analyzed using SPSS-23 and AMOS-24. Results: Confirmatory and exploratory factor analysis revealed a three-factor structure for the YMRS. Cronbach's alpha coefficient of 0.72 indicated the acceptable reliability of YMRS. The cutoff point, sensitivity, and specificity of the YMRS were found to be 12.5, 0.93, and 0.96, respectively. Conclusion: According to the study results, YMRS showed adequate psychometric properties in the Iranian population. Therefore, it can be considered as a valuable instrument in screening patients with bipolar disorder in the manic phase.
Development and application of the mania rating guide (MRG)
Revista Brasileira de …, 2003
In this article we present the development and application of the Mania Rating Guide (MRG), a semi-structured interview. This guide was created in order to assist the filling of three mania Scales: Mania Rating Scale, Bech-Rafaelsen Mania Scale and Clinician-Administered Rating Scale for Mania. The MRG consists of twenty-one Psychopathological Dimensions, that correspond to the Items of the original Scales, and are structured in Questions. The guide was applied to fifteen manic patients admitted in the Psychiatric Unit of the Clinical Hospital of Porto Alegre. A psychiatrist interviewed them using the MRG, and the interviews were videotaped. Afterwards, three independent raters scored the Mania scales based on the films. The impression of the raters was that the MRG allows not only to easily score all the Items of the Scales but also to cover the wide spectrum of the symptomatological presentation of a manic syndrome.
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.
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.
The Altman Self-Rating Mania Scale
Biological Psychiatry, 1997
We report on the development, reliability, and validi O, of the Altman Self-Rating Mania Scale (ASRM). The ASRM was completed during medication washout and after treatment by 22 schizophrenic, 13 schizoaffective, 36 depressed, and 34 manic patients. The Clinician-Administered Rating Scale for Mania (CARS-M) and Mania Rating Scale (MRS) were completed at the same time to measure concurrent validi~'. Test-retest reliabili~' was assessed separately on 20 depressed and ]0 manic" patients who completed the ASRM twice during washout. Principal components analysis of ASRM items revealed three .factors." mania, psychotic symptoms, and irritability. Baseline mania subscale scores were significantly higher for manic patients compared to all other diagnostic groups. Manic patients had significantly decreased posttreatment scores for all three subscales. ASRM mania subscale scores were significantly correlated with MRS total scores (r := . 718) and CARS-M mania subscale scores (r = .766). Test-retest reliability for the ASRM was significant for all three subscales. Significant differences in severi~' levels were fi)und fi)r some symptoms between patient ratings on the ASRM and clinician ratings on the CARS-M. Mania subscale scores of greater than 5 on the ASRM resulted in values of 85.5% fbr sensitivity and 87.3%for specificity. Advantages of the ASRM over other self-rating mania scales are discussed.
The Observer-Rated Scale for Mania (ORSM): development, psychometric properties and utility
The diagnosis of mania largely depends on the quality of information the physician is provided with. Often, the patient cannot give an accurate account of the symptom development and thus information from relatives and friends is required. No systematic rating instrument is available, however, to facilitate this. In this study, the psychometric properties of the 49-item Observer-Rated Scale for Mania (ORSM) are reported. The scale was used in 113 inpatients and the following psychometric aspects were assessed: reliability, test-retest reliability, construct validity (factor analysis, discriminant analysis, comparison of means), extreme-group validity, prognostic validity, sensitivity, specificity, positive and negative predictive values. The ORSM proved highly valid and reliable. Factor analysis revealed three factors which were labelled euphoric mania, instable mania and psychotic mania. The ORSM is a useful instrument to help non-professionals who are in regular contact with the patient diagnosed a manic/mixed episode. It thus complements existing rating scales for mania, which are either designed for professionals or are self-rating instruments.
An investigation of the self-report manic inventory as a diagnostic and severity scale for mania
Comprehensive Psychiatry, 1996
The initial study on the Self-Report Manic Inventory (SRMI} reported that it reliably diagnosed mania. In the current study, we replicated the initial study on the SRMI. We also evaluated its ability to quantify manic symptomatology and to measure change during inpatient treatment. The findings show that manic patients are capable of reporting their symptoms, regardless of their insight into their condition. They also confirm that the SRMI is a reliable diagnostic instrument and that it performs consistently over time when used with a 1-week time format. The SRMI is also sensitive to clinical improvement in hospitalized patients undergoing treatment. The SRMI correlated well with the Young Mania-Rating Scale (YMRS), which served as an external validator of SRMI scores at the beginning and end of hospitalization. Factor analysis produced two groups of manic subjects who closely resemble the hedonistic euphoric type and the energized dysphoric type initially reported by Shugar et al.

decreased need for sleep, or racing thoughts. Roughly 69% of cases also showed poor judgment, whereas only half of bipolar cases demonstrated flight of ideas, and slightly more than one-third showed hypersexuality or psychotic features. [3] Kraepelin later described six types of mixed states based on various combinations of mood, will (volition), and thought processes: manic stupor (elevated mood but decreased will and thought), depressive mania (depressed mood but elevated will and thought), excited depression (depressed mood and will but elevated thought), depression with
Measurement of mania and depression
2011
Background: In psychiatry, the assessment of symptom severity is being increasingly assisted by rating scales, in clinical practice as well as in research and quality control. Transforming the subjective symptoms of psychiatric disorders into valid numerical measures is subjected to numerous confounding factors. Careful evaluation of rating scales is therefore essential. This doctoral project arose from a clinical need for a useful self-rating scale for affective symptoms at an outpatient clinic for affective disorders. No existing rating scales fulfilling the clinical need were found in the literature. Aims: The aims of the doctoral project were to develop and evaluate a self rating scale for measurement of severity in depressive, manic and mixed affective states and to explore if Item Response Theory (IRT) is useful for evaluation and improvement of rating scales for mania and depression. A further aim was to investigate if Randomized Controlled Studies of Antidepressants (RCT-ADs...
