[Reliability, validity and sensitivity to change of the psychiatric evaluation scale of Krawiecka]. / Fiabilidad, validez y sensibilidad al cambio de la escala de evaluación psiquiátrica de Krawiecka.

An analysis of the inter-rater reliability, validity and sensibility to clinical change of Krawiecka's "Psychiatric Evaluation Scale" was carried out. Reliability was found to be fair to good in all items and the total score, the lowest values corresponding to "blunted-incongruent affect". Global validity was tested against Endicott et al's GAS and partial validity of "depression" against Beck Depression Inventory. In both cases positive and significant correlations were attained. The scale was also found to be sensitive to clinical changes in the following items: anxiety, delusions, hallucinations, incoherent-irrelevant speech and total score. Total score at one month after discharge significantly correlated with Strauss-Carpenter's "Out-come Scale" Endicott et al's GAS and a measure of daily instrumental activities eight months later.

[Factorial structure and internal consistency of the psychiatric evaluation scale of Krawiecka]. / Estructura factorial y consistencia interna de la escala de evaluacíon psiquiátrica de Krawiecka.

An analysis of internal consistency and factorial structure of Krawiecka's Psychiatric Evaluation Scale was carried out. Global alpha coefficient was found to be 0.36. Factorial analysis revealed the presence of three factors that accounted for 60% of total variance. Factor one included blunted-incongruent affect, poverty of speed and psychomotor retardation. Factor two loaded on delusions, hallucinations and anxiety-agitation and the third factor on incoherent-irrelevant speech and depression.
