Typical Antipsychotics

BackgroundAntipsychotic drugs are effective in schizophrenic disorders, but they are also used to treat other psychiatric conditions. Typical antipsychotics cause important extrapyramidal symptoms (EPS), which frequently result in non-compliance with antipsychotic medication. It has been stated that the second-generation antipsychotics (atypical) provoke EPS side effects less frequently than typical antipsychotics. However, there is some controversy around this statement, especially because of inefficient measures of EPS. Clinical assess of EPS normally relies upon observer-based ratings, but their reliability and validity has not been consistently established.ObjectiveIn the present work, we have explored the convergent and discriminant validity of the Abnormal Involuntary Movement Scale (AIMS) and the Simpson-Angus Scale (SEE), in a Spanish sample of patients with severe mental disorders. Patients could be under typical or atypical antipsychotics, antidepressants, benzodiacepines, or a combination of these.MethodSixty-one patients with severe mental disorders from the Mental Health Day Hospital of St. Agustín (Linares, Spain) participated in the study. Inclusion criteria were DSM-V diagnosis of schizophrenia or schizophrenic disorder, bipolar, or borderline personality disorders, and age between 18-61. In order to explore the discrimination capacity of each rating scale, Receiver Operator Characteristic (ROC) analyses were conducted.ResultsROC curves indicated a suitable construct validity of the scales in the measurement of drug-induced motor symptoms. However, the scales were not sensitive to the number of years under treatment.ConclusionsIn line with previous research, our results question the use of rating scales as the only measure in the evaluation of EPS symptoms.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Objective: To evaluate the reliability and validity of the English and Spanish versions of the Strengths and Weaknesses of ADHD-symptom and Normal-behavior (SWAN) rating scale. Method: Parents of preschoolers completed both a SWAN and the well-established Strengths and Difficulties Questionnaire (SDQ) on two separate occasions over a span of 3 months; instruments were in the primary language of the family (English or Spanish). Results: Psychometric properties for the English and Spanish versions of the SWAN were adequate, with high internal consistency and moderate test–retest reliability. Skewness and kurtosis statistics for the SWAN were within the range expected for a normally distributed population. The SWAN also demonstrated adequate convergent and discriminant validity in correlations with the various subscales of the SDQ. Conclusion: Psychometric properties of both the English and Spanish versions of the SWAN indicate that it is a reliable and valid instrument for measuring child attention and hyperactivity. The stability of ratings over time in this preschool sample was moderate, which may reflect the relative instability of these characteristics in preschool children.

Objective: Due to its pleomorphic phenomenology, the clinical features of bipolar depression are difficult to assess. The objective of the present study was therefore to explore the internal structure of the Bipolar Depression Rating Scale (BDRS) in terms of the phenomenological characteristics of bipolar depression. Methods: Sixty patients with DSM-IV bipolar depression completed the BDRS, depression and excitement subscales of the Positive and Negative Syndrome Scale (PANSS-D and PANSS-E), 17-item Hamilton Depression Rating Scale, Montgomery–Äsberg Depression Rating Scale, Young Mania Rating Scale (YMRS), and the Drug-Induced Extrapyramidal Symptoms Scale. The internal structure of the BDRS was explored through hierarchical cluster analysis (HCA) using Ward's method and multidimensional scaling (MDS). Results: From 20-item BDRS data, the HCA yielded two symptom clusters. The first cluster included 12 items of conventional depressive symptoms. The second cluster included eight items of mixed symptoms. The MDS identified a depressive–mixed dimension. The depressive symptom cluster showed a more cohesive and conglomerate cluster structure on the MDS map compared to the mixed symptom cluster. After controlling for the effects of treatment-emergent extrapyramidal symptoms, strong positive correlations were observed between the BDRS and other depression rating scales, and the BDRS also weakly correlated with the YMRS and the PANSS-E. Conclusions: The internal structure of BDRS appears to be sensitive to complex features of bipolar depression. Hence, the BDRS may have an advantage in evaluating clinical changes in patients with bipolar depression within the therapeutic process.

Second Language Performance

Abstract The two most common approaches to rating second language performance pose problems of reliability and validity. An alternative method utilizes rating scales that are empirically derived from samples of learner performance; these scales define boundaries between adjacent score levels rather than provide normative descriptions of ideal performances; the rating process requires making two or three binary choices about a language performance being rated. A procedure, that consists of a series of five explicit tasks, is used to construct a rating scale. The scale is designed for use with a specific population and a specific test task. A group of primary school ESL teachers used this procedure to make two speaking tests, including elicitation tasks and rating scales, for use in their school district. The tests were administered to 255 sixth grade learners. The scales were found to be highly accurate for scoring short speech samples, and were quite efficient in time required for scale development and rater training. Scales exhibit content relevance in the instructional setting. Development of this type of scale is recommended for use in high-stakes assessment.

Introduction:Long-acting depot antipsychotic medication is associated with extrapyramidal side effects (EPS). This may reduce adherence to medication, and precipitate relapse (1). Clearly, EPS is a major drawback and early detection is essential. However, in an earlier review of patients’ medical notes, we identified only one patient with an examination that recorded the presence of EPS. Despite the fact that a number of rating scales are available. We proposed that the application of these rating scales, would allow us to improve the assessment of EPS.Method:All patients prescribed a depot antipsychotic or long-acting risperidone injection, were identified. the Barnes Akathisia Scale (2) was chosen to rate akathisia, a modified Simpson-Angus scale (3) was chosen to rate parkinsonism and the Abnormal Involuntary Movement Scale (4) was chosen to rate tardive dyskinesia.Results:A total of 43 patients were evaluated. 23 (53%) patients showed drug induced EPS. the total number of positive cases of akathisia was 12 (28%), and 10 (23%) patients were found to have tardive dyskinesia. 13 (30%) patients were found to have drug induced parkinsonism.Conclusions:Our screening programme has identified high rates of previously undiscovered drug induced EPS.

This study is the first empirical investigation of the 1964 Tversky condition applied to rating scales. The Tversky condition posits that the 3-response format will be optimum if testing time is proportional to the length of the test. To this end, 2-, 3-, 4-, and 5-response category forms of a 10-item measure of attitudes in science were randomly administered to 241 third grade students. Reliability and validity were computed for each form. No significant differences were found among the reliability coefficients or among the validity coefficients. The Tversky condition was not confirmed for rating scales. These findings are consistent with results from other studies regarding the lack of substantial differences among reliability and validity coefficients as the number of response categories in a rating scale are varied.

Optimal Cutoff Point

Introduction. To date, no rating scales for detecting apathy in Parkinson’s disease (PD) patients have been validated in Spanish. For this reason, the aim of this study was to validate a Spanish version of Lille apathy rating scale (LARS) in a cohort of PD patients from Spain.Participants and Methods. 130 PD patients and 70 healthy controls were recruited to participate in the study. Apathy was measured using the Spanish version of LARS and the neuropsychiatric inventory (NPI). Reliability (internal consistency, test-retest, and interrater reliability) and validity (construct, content, and criterion validity) were measured.Results. Interrater reliability was 0.93. Cronbach’sαfor LARS was 0.81. The test-retest correlation coefficient was 0.97. The correlation between LARS and NPI scores was 0.61. The optimal cutoff point under the ROC curve was-14, whereas the value derived from healthy controls was-11. The prevalence of apathy in our population tested by LARS was 42%.Conclusions. The Spanish version of LARS is a reliable and useful tool for diagnosing apathy in PD patients. Total LARS score is influenced by the presence of depression and cognitive impairment. However, both disorders are independent identities with respect to apathy. The satisfactory reliability and validity of the scale make it an appropriate instrument for screening and diagnosing apathy in clinical practice or for research purposes.
