Validation of the Spanish version of Soane's ISA Engagement Scale

The interest in the study of engagement in the academic field can be seen through the increasing number of results in Google Scholar and in Scopus, going from barely 20 results between 2000 and 2005 to more than 500 in Scopus and more than 1100 in Google Scholar between 2011 and 2015. Soane et al. (2012) propose a unified theoretical framework as the basis of the psychological mechanism of engagement, grounded on the approach of Kahn (1990). The aim of this paper is to analyze the psychometric properties of the Spanish version of the ISA engagement scale in a sample of 477 employees of the administration and services sector in a Spanish public university. Keeping the original design of the English version of the scale, the proposed factorial structure is validated with the good fit of the data according to the revised goodness of fit indices; reliability and the results of the analysis of construct validity.

Insight assessment in psychosis and psychopathological correlates: validation of the Spanish version of the Schedule for Assessment of Insight - Expanded Version

Background and Objectives: Lack of insight is a cardinal feature of psycho­sis. Insight has been found to be a multidimensional concept, including awareness of having a mental illness, ability to relabel psychotic phenomena as abnormal and compliance with treatment., which can be measured with the Schedule for Assessment of Insight (SAI-E). The aim of this study was to validate the Spanish version of SAI-E. Methods: The SAI-E was translated into Spanish and back-translated into English, which was deemed appropriate by the original scale author. Next, the Spanish version of the SAI-E was administered to 39 patients with schizophrenia or schizoaffective disorder (DSM-IV criteria) from a North Peruvian psychiatric hospital. The Positive and Negative Syndrome Scale for Schizophrenia (PANSS) and the Scale of Unawareness of Mental Disorder (SUMD) were also administered. Specifically, internal consistency and convergent validity were assessed. Results: Internal consistency between the 11 items of the SAI-E was found to be good to excellent (α = 0.942). Compliance items did not contribute to internal consistency (A = 0.417, B = 572). Inter-rater reliability was excellent (ICC = 0.99). Regarding concurrent validity, the SAI-E total score correlated negatively with the lack of insight and judgement item of the PANNS (r = -0.91, p <0.01) and positively with the SUMD total score (r = 0.92, p <0.001). Conclusions: The Spanish version of the SAI-E scale was demonstrated to have both excellent reliability and external validity in our sample of South American Spanish-speaking patients with schizophrenia spectrum disorders.
