Test Retest Reliability

SummaryNinety-four psychiatric in-patients, receiving regular antipsychotic medication, were videotaped using a standard procedure. The tapes were rated by blind observers using a simple scoring system for the duration of abnormal movements. Using this combined videotape and rating scale assessment technique the re-rating reliability, inter-rater reliability and test-retest reliability were high. In order to demonstrate the validity of the technique the rating scale scores in a sub-sample of 30 patients, were compared with the assessment of three experienced clinicians on the same patients, and AIMS scores. Central (lip, tongue, jaw and neck movements) scores showed close agreement with the clinicians' assessment, suggesting that clinical diagnosis is based principally on the presence and severity of oro-facial dyskinesia. Total rating scale scores were in close accord with total AIMS scores. When the two scales were carried out on the same patients on the same occasion a diagnostic criterion level of 2 or more on the central score produced a tardive dyskinesia prevalence rate identical to that produced by an AIMS criterion level of 2 or more on the global severity rating. The tardive dyskinesia prevalence rate based on the central score criterion level showed an increase with age.

Headache Impact

Objective: The purpose of this study was to assess psychometric properties of the six-item Headache Impact Text (HIT-6™) across episodic and chronic migraine. Methods: Using a migraine screener and number of headache days per month (HDPM), participants from the National Survey of Headache Impact (NSHI) study and the HIT-6 validation study (HIT6-V) were selected for this study. Eligible participants were categorized into three groups: chronic migraine (CM: ≥ 15 HDPM); episodic migraine (EM: < 15 HDPM); non-migraine headaches. Reliability and validity of the HIT-6 were evaluated. Results: A total of 2,049 survey participants met the inclusion/exclusion criteria for this study. Participants were identified as 6.4% CM; 42.1% EM; 51.5% non-migraine, with respective mean HIT-6 scores: 62.5 ± 7.8; 60.2 ± 6.8; and 49.1 ± 8.7. High reliability was demonstrated with internal consistency (time1/time2) of 0.83/0.87 in NSHI, and 0.82/0.92 in HIT6-V. Intra-class correlation for test-retest reliability was very good at 0.77. HIT-6 scores correlated significantly ( p < .0001) with total Migraine Disability Assessment Scale scores ( r = 0.56), headache pain severity ( r = 0.46), and HDPM ( r = 0.29). Discriminant validity analysis showed significantly different HIT-6 scores ( F = 488.02, p < .0001) across the groups. Conclusion: Results from these analyses confirm that the HIT-6 is a reliable and valid tool for discriminating headache impact across episodic and chronic migraine.

Item Scale

As a measure of mathematics anxiety, the Mathematics Anxiety Rating Scale (MARS) has been a major scale used for research and clinical studies since 1972. Despite the usefulness of the original scale, researchers have sought a shorter version of the scale partly to reduce the administration time of the original 98-item scale. This study created a shorter version of the MARS and provides reliability and validity information for the new version. The Cronbach alpha of .96 indicated high internal consistency, while the test-retest reliability for the MARS 30-item was .90 ( p < .001). The validity data confirm that the MARS 30-item test is comparable to the original MARS 98-irem scale.

Idiopathic Dystonia

Background: The Dyskinesia Impairment Scale (DIS) is a new assessment scale for dystonia and choreoathetosis in children and youth with dyskinetic cerebral palsy. Today, the Burke–Fahn–Marsden Dystonia Rating Scale (BFM) is mostly used to assess dystonia in children with inherited dystonia. The aim of this study was to assess reliability and validity of the DIS in children and youth with inherited or idiopathic dystonia. Methods: Reliability was measured by (1) the intraclass correlation coefficients (ICCs) for inter-rater and test-retest reliability, as well as (2) standard error of measurement (SEM) and minimal detectable difference (MDD). For concurrent validity of the DIS-dystonia subscale, the BFM was administered. Results: In total, 11 males and 9 females (median age 16 years and 7 months, range 6 to 24 years) were included. For inter-rater reliability, the ICCs for the DIS total score and the dystonia and choreoathetosis subscale scores were 0.83, 0.87, and 0.71, respectively. For test-retest reliability, the ICCs for the DIS total score and the dystonia and choreoathetosis subscale scores were 0.95, 0.88, and 0.93, respectively. The SEM and MDD for the total DIS were 3.98% and 11.04%, respectively. The Spearman correlation coefficient between the dystonia subscale and the BFM was 0.88 (p < 0.01). Conclusions: Good to excellent inter-rater, test-retest reliability, and validity were found for the total DIS and the dystonia subscale. The choreoathetosis subscale showed moderate inter-rater reliability and excellent test-retest reliability. The DIS may be a promising tool to assess dystonia and choreoathetosis in children and young adults with inherited or idiopathic dystonia.

Aim: To translate the Quality of Life in Late-Stage Dementia (QUALID) Scale into Norwegian, and to evaluate the test-retest reliability and validity of the scale. Method: QUALID was translated according to standardised procedures. Residents with dementia living in nursing homes were included in the study and assessed using QUALID, Cornell Scale for Depression in Dementia, Neuropsychiatric Inventory, Physical Self-Maintenance Scale and Clinical Dementia Rating Scale. Results: Cronbach's α of QUALID was 0.79. In the reliability study, the intra-class correlation was 0.83. The validity study showed a strong association between depressive symptoms and QUALID, and a moderate association between QUALID and assessments of level of functioning and agitation. Conclusions: The Norwegian version of QUALID is a reliable and valid scale for assessing quality of life in nursing home residents with dementia.

Objective Anosognosia is a common phenomenon in individuals with dementia. Anosognosia Questionnaire for dementia (AQ-D) is a well-known scale for evaluating anosognosia. This study aimed to establish a Korean version of the AQ-D (AQ-D-K) and to evaluate the reliability and validity of the AQ-D-K in patients with Alzheimer’s disease (AD) dementia.Methods We translated the original English version of AQ-D into Korean (AQ-D-K). Eighty-four subjects with very mild or mild AD dementia and their caregivers participated. Reliability of AQ-D-K was assessed by internal consistency and one-month test-retest reliability. Construct validity and concurrent validity were also evaluated.Results Internal consistencies of the AQ-D-K patient form and caregiver form were high (Cronbach alpha 0.95 and 0.93, respectively). The test-retest reliability of AQ-D-K measured by intra-class correlation coefficient was 0.84. Three factors were identified: 1) anosognosia of instrumental activity of daily living; 2) anosognosia basic activity of daily living; and 3) anosognosia of depression and disinhibition. AQ-D-K score was significantly correlated with the clinician-rated anosognosia rating scale (ARS), center for epidemiological studies-depression scale (CES-D) and state-trait anxiety inventory (STAI).Conclusion The findings suggest that the AQ-D-K is a reliable and valid scale for evaluating anosognosia for AD dementia patients using Korean language.

Psychiatric Rating Scale

Tardive dyskinesia, a syndrome of involuntary motor movements, can be a permanent consequence of the long-term use of antipsychotic drugs. While there is no well-established drug treatment, case reports and the results of a few clinical studies suggest that drugs that facilitate the GABA-ergic system may decrease the abnormal movements. One such class of drugs is the benzodiazepines. We administered diazepam to 13 subjects in a 24-week, crossover design study. Tardive dyskinesia and psychopathology were assessed by blind raters using the Abnormal Involuntary Movement Scale and the Brief Psychiatric Rating Scale (BPRS). The means of all movement measurements improved from the baseline, with orofacial, subtotal, symptom severity, and total reaching significance. However, we were unable to demonstrate a drug effect; the patients improved to a similar degree whether or not they received diazepam. Their psychiatric disorders did not worsen with diazepam administration and, in fact, improved slightly; the activation factor of the BPRS was significantly improved over baseline. Our results suggest that diazepam is not effective in managing the movements of tardive dyskinesia and that behavior modification strategies be investigated to help patients control symptoms.
