TL;DR: The MRS score correlated highly with an independent global rating, and with scores of two other mania rating scales administered concurrently, and also correlated with the number of days of subsequent stay in hospital.
Abstract: An eleven item clinician-administered Mania Rating Scale (MRS) is introduced, and its reliability, validity and sensitivity are examined. There was a high correlation between the scores of two independent clinicians on both the total score (0.93) and the individual item scores (0.66 to 0.92). The MRS score correlated highly with an independent global rating, and with scores of two other mania rating scales administered concurrently. The score also correlated with the number of days of subsequent stay in hospital. It was able to differentiate statistically patients before and after two weeks of treatment and to distinguish levels of severity based on the global rating.

TL;DR: The Clinical Dementia Rating (CRD) was developed for a prospective study of mild senile dementia—Alzheimer type (SDAT), and was found to distinguish unambiguously among older subjects with a wide range of cognitive function.
Abstract: Accurate clinical staging of dementia in older subjects has not previously been achieved despite the use of such methods as psychometric testing, behavioural rating, and various combinations of simpler psychometric and behavioural evaluations The Clinical Dementia Rating (CRD), a global rating device, was developed for a prospective study of mild senile dementia--Alzheimer type (SDAT) Reliability, validity, and correlational data are discussed The CRD was found to distinguish unambiguously among older subjects with a wide range of cognitive function, from healthy to severely impaired

TL;DR: The SANS is complemented by a Scale for the Assessment of Positive Symptoms (SAPS), which permits detailed evaluation and global ratings of hallucinations, delusions, positive formal thought disorder and bizarre behaviour and taken together, the two scales provide a comprehensive set of rating scales.
Abstract: The Scale for the Assessment of Negative Symptoms (SANS) was the first instrument developed in order to provide for comprehensive assessment of negative symptoms in schizophrenia (Andreasen, 1982, 1983). It consists of five scales that evaluate five different aspects of negative symptoms: alogia, affective blunting, avolition-apathy, anhedonia-asociality, and attentional impairment. Each of these negative symptoms can be rated globally, but in addition detailed observations are made in order to achieve the global rating. It is complemented by a Scale for the Assessment of Positive Symptoms (SAPS), which permits detailed evaluation and global ratings of hallucinations, delusions, positive formal thought disorder and bizarre behaviour (Andreasen, 1984). Taken together, the two scales provide a comprehensive set of rating scales in order to measure the symptoms of schizophrenia and to assess their change over time.

TL;DR: The validity of a global rating of change as a reflection of meaningful change in patient status was supported by the stability of the Physical Impairment Index across the study period in patients defined as stable by the global rating and by the decrease in physical impairment across thestudy period.
Abstract: Background and Purpose. The quality of a disability scale should dictate when it is used. The purposes of this study were to examine the validity of a global rating of change as a reflection of meaningful change in patient status and to compare the measurement properties of a modified Oswestry Low Back Pain Disability Questionnaire (OSW) and the Quebec Back Pain Disability Scale (QUE). Subjects. Sixty-seven patients with acute, work-related low back pain referred for physical therapy participated in the study. Methods. The 2 scales were administered initially and after 4 weeks of physical therapy. The Physical Impairment Index, a measure of physical impairment due to low back pain, was measured initially and after 2 and 4 weeks. A global rating of change survey instrument was completed by each subject after 4 weeks. Results. An interaction existed between patients defined as improved or stable based on the global rating using a 2-way analysis of variance for repeated measures on the impairment index. The modified OSW showed higher levels of test-retest reliability and responsiveness compared with the QUE. The minimum clinically important difference, defined as the amount of change that best distinguishes between patients who have improved and those remaining stable, was approximately 6 points for the modified OSW and approximately 15 points for the QUE. Conclusion and Discussion. The construct validity of the global rating of change was supported by the stability of the Physical Impairment Index across the study period in patients defined as stable by the global rating and by the decrease in physical impairment across the study period in patients defined as improved by the global rating. The modified OSW demonstrated superior measurement properties compared with the QUE.

TL;DR: The purpose of this article is to assist appropriate interpretation of the GRC results and to provide evidence-informed advice to guide design and administration of GRC scales.
Abstract: Most clinicians ask their patients to rate whether their health condition has improved or deteriorated over time and then use this information to guide management decisions. Many studies also use patient-rated change as an outcome measure to determine the efficacy of a particular treatment. Global rating of change (GRC) scales provide a method of obtaining this information in a manner that is quick, flexible, and efficient. As with any outcome measure, however, meaningful interpretation of results can only be undertaken with due consideration of the clinimetric properties, strengths, and weaknesses of the instrument. The purpose of this article is to summarize this information to assist appropriate interpretation of the GRC results and to provide evidence-informed advice to guide design and administration of GRC scales. These considerations are relevant and applicable to the use of GRC scales both in the clinic and in research.
