The positive and negative syndrome scale (PANSS) for schizophrenia.

Objective: This pilot, twelve-week, open-label study examined the effect of clozapine orally disintegrating tablet or ODT in patients with schizophrenia and schizoaffective disorder utilizing Positive and Negative Syndrome Scale PANSS as a long-term outcome measurement tool. Methods: The final study sample consisted of nineteen subjects who were residents a long-term care psychiatric facility in Pomona, California. PANSS were administered at baseline, week-4, week-8 and week Paired sample t-tests were used to calculate the statistical significance of the mean differences for scores at baseline and week Results: Mean differences from baseline indicated significant improvement on total score, as well as positive, negative, cognitive and general psychopathology subscales after twelve weeks of treatment. The greater average reduction in the negative syndrome subscale across the twelve weeks possibly illustrates the ability of clozapine ODT in improving negative symptoms, including cognitive function which is their ability to participate in their personal care and creative expressions in dance, arts, games, poetry to a greater extent their overall, quality of life and living along with the effect on positive symptoms. Conclusion: Overall, clozapine proved to affect a broad range of psychopathology including cognitive functions in this schizophrenic sample.

The journal is oriented to the study of mental illnesses, their pathological processes, and their psychosocial consequences, and has as its aim to disseminate the scientific advances in all fields related to the illness and mental health. It accepts unpublished works on psychiatry and mental health, and its medical and social repercussions. For this reason, space is provided in the Journal for works in the biological, clinical and psychosocial field. Manuscripts are evaluated, before being accepted, by external reviewers peer-review. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. CiteScore measures average citations received per document published. Read more.

The clinician-administered interview takes, on average, 45 minutes. The BPRS may be useful when assessment of general symptoms is all that is needed and when a high level of precision regarding positive and negative symptoms is unnecessary. MHS Inc.

The positive-negative distinction has emerged as a meaningful basis for understanding the heterogeneity of schizophrenia and treatment alternatives, but its delineation requires carefully devised, well validated techniques. This article considers the psychometric requisites for such an instrument and describes 30 criteria associated with operationalization, scale construction, and standardization. The Positive and Negative Syndrome Scale PANSS is described as an effort to approach these principles of test standardization, and its clinical and research applications are discussed.

Metrics details. Statistical models based on item response theory were used to examine a the performance of individual Positive and Negative Syndrome Scale PANSS items and their options, b the effectiveness of various subscales to discriminate among individual differences in symptom severity, and c the appropriateness of cutoff scores recently recommended by Andreasen and her colleagues to establish symptom remission. Option characteristic curves were estimated using a nonparametric item response model to examine the probability of endorsing each of 7 options within each of 30 PANSS items as a function of standardized, overall symptom severity. Our data were baseline PANSS scores from patients with schizophrenia or schizoaffective disorder who were enrolled between and in either a large, naturalistic, observational study or else in 1 of 12 randomized, double-blind, clinical trials comparing olanzapine to other antipsychotic drugs. We also identified key areas for improvement or revision in items and options within the General Psychopathology subscale. The Positive and Negative subscale scores are not only more discriminating of individual differences in symptom severity than the General Psychopathology subscale score, but are also more efficient on average than the item total score. Of the 8 items recently recommended to establish symptom remission, 1 performed markedly different from the 7 others and should either be deleted or rescored requiring that patients achieve a lower score of 2 rather than 3 to signal remission.

Stanley R. Kay, Abraham Fiszbein, Lewis A. The variable results of positive-negative research with schizophrenics underscore the importance of well-characterized, standardized measurement techniques. Based on two established psychiatric rating systems, the item PANSS was conceived as an operationalized, drug-sensitive instrument that provides balanced representation of positive and negative symptoms and gauges their relationship to one another and to global psychopathology. It thus constitutes four scales measuring positive and negative syndromes, their differential, and general severity of illness.

Item response analysis of the Positive and Negative Syndrome Scale

Вы летали когда-нибудь на Лирджете-60.

Кто знает, что произойдет, прежде чем он решит освободить Сьюзан… если он ее вообще освободит. Я обязан позвонить в службу безопасности, - решил.  - Что еще мне остается? - Он представил Хейла на скамье подсудимых, вываливающего все, что ему известно о Цифровой крепости.

 Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов. Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам. Какие-то безумцы ныряли со сцены в это людское море, и его волны швыряли их вперед и назад, как волейбольные мячи на пляже. Откуда-то сверху падали пульсирующие стробоскопические вспышки света, придававшие всему этому сходство со старым немым кино.
