RESUMO

OBJECTIVE: This study presents the cultural and linguistic adaptation and psychometric properties of the Argentine version of the Quality of Life in Epilepsy Inventory (QOLIE-31P) scale. METHODS: An instrumental study was carried out. A version of QOLIE-31P translated into Spanish was provided by the original authors. To assess the content validity, evaluation of expert judges was requested, and the degree of agreement was determined. The instrument was administered to 212 people with epilepsy (PWE) of Argentina, together with the BDI-II, B-IPQ and a sociodemographic questionnaire. A descriptive analysis of the sample was carried out. Discriminative capacity of the items was performed. Cronbach's alpha was calculated to assess reliability. To study the dimensional structure of the instrument, a confirmatory factorial analysis (CFA) was performed. Convergent and discriminant validity was tested through mean difference tests, linear correlation, and regression analysis. RESULTS: Aiken's V coefficients ranged between .90 and 1 (acceptable), which allows to state that a conceptually and linguistically equivalent version of the QOLIE-31P was reached. Cronbach's Alpha of 0.94 was obtained for the Total Scale (optimal). As a result of CFA, 7 factors were obtained, being the dimensional structure similar to the original version. Also, unemployed PWE reported significant lower scores than employed PWE. Finally, QOLIE-31P scores negatively correlated with depression symptom severity and negative illness perception. CONCLUSION: The Argentine version of the QOLIE-31P is a valid and reliable instrument, presenting good psychometric properties, such as high internal consistency and a dimensional structure similar to that of the original version.

RESUMO

Resumen Se han revisado artículos que estudiaron la calidad de vida en las personas con crisis no epilépticas psicógenas (CNEP) y crisis epilépticas. Se siguió la guía PRISMA y, previo a la búsqueda, se realizó un protocolo publicado en PROSPERO. Se incluyeron estudios aleatorizados y no aleatorizados, de tipo cuantitativo o mixtos, de corte transversal o longitudinal, escritos en lengua inglesa o española publicados hasta el año 2020, y cuyos participantes fueran mayores de 16 años. Luego de filtrar los resultados según los criterios de selección, se incluyeron 11 artículos y una tesis doctoral cuyos años de publicación datan de 1998 a 2020. En su mayoría, se informaba que las personas con CNEP tenían menor calidad de vida, asociadas a presencia de psicopatología, así como también a la toma de medicación antiepiléptica, factores sociodemográficos y relacionados con las crisis (frecuencia, severidad y duración de enfermedad), funcionamiento familiar, trauma y somatización.

Abstract Psychogenic non epileptic seizures (PNES) are disruptive changes in behaviour, thought, or emotion that resemble an epileptic seizure, but without paroxysmal neuronal discharge detectable by electroencephalography (EEG), and are not caused by another medical condition. On the other hand, epileptic seizures (ES) are defined as clinical events that reflect the presence of hypersynchronous discharges of neurons located in the cerebral cortex, which have the particularity of starting and ending abruptly. The diagnosis of epilepsy is made when an epileptic seizure was experienced and there is a risk of having another. The objective of this paper is to present the results of a systematic review of articles that have studied quality of life in people with PNES and ES. This review has been performed following the PRISMA guide (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Prior to the beginning of the search, a protocol was carried out and it is published for consultation in the International prospective register of systematic reviews (PROSPERO). The review includes randomized and non-randomized, quantitative or mixed, cross-sectional or longitudinal studies, published in English or Spanish until 2020. In addition, participants had to be over 16 years old. PNES diagnosis must have been confirmed by video-electroencephalography (VEEG) or a similar procedure-which is considered the gold standard for the diagnosis of PNES.

RESUMO

OBJECTIVES: Psychiatric disorders are frequently found in both patients with PNES and DRE, making the differential diagnosis even more complex. The aim of this study was to analyze and compare psychiatric aspects and the quality of life in patients with psychogenic non-epileptic seizures (PNES) and drug resistant epilepsy (DRE). METHODS: Patients admitted to video-electroencephalograpy (VEEG) unit with confirmed PNES and DRE were included. Demographical characteristics, psychiatric diagnosis according to SCID I and II of DSM IV, pharmacological treatment, general functioning measured with GAF (Global assessment of functionality), quality of life (QoL) using QlesQSF (Quality of Life Enjoyment and Satisfaction Questionnaire Short Form) and depression severity using BDI II (Beck depression inventory), were compared between the groups. Non-parametric tests, chi square test, and logistic regression were used for statistical analysis. RESULTS: 148 patients consecutively admitted to VEEG were included (DRE n = 97; PNES n = 51). Somatization disorder (RR: 13.02, 95% CI: 1.23-137.39, p = 0.03) and a history of trauma (RR: 8.66, 95% CI: 3.21-23.31, p = 0.001) were associated with PNES. The QlesQ score and the GAF score were lower with a higher prevalence of suicide attempts in the PNES group (p < 0.01). A negative correlation was observed between the severity of depression and the quality of life (DRE r = - 0.28, p = 0.013; PNES r = - 0.59, p = 0.001). CONCLUSIONS: Higher psychiatric comorbidity with poorer QoL were found in PNES patients compared to DRE. However, depression comorbidity negatively affected the QoL in both groups. Future studies based on illness perception will be orientated to complete this analysis.

RESUMO

PURPOSE: To examine the effects of a three-session psychoeducational intervention on patients diagnosed with psychogenic non-epileptic seizures (PNES) in an Argentinian public hospital. It was hypothesized that patients would experience improvements in their understanding of PNES, illness perception and affective scores, but might not necessarily experience a significant change in post-traumatic and dissociative symptoms and in seizure frequency. METHODS: This study included 12 patients (10 women, 2 men) who were invited to participate in a psychoeducational group after receiving a V-EEG confirmed diagnosis of PNES. The group consisted of 3 sessions lasting 2 h each. Pre and post measures included Psychoeducational Intervention Questionnaire, State-Trait Anxiety Inventory, Beck Depression Inventory-II, Brief Illness Perception Questionnaire, Posttraumatic Stress Disorder Diagnostic Scale 5, Dissociative Experiences Scale (DES-M). RESULTS: This psychoeducational intervention produced results that were similar to interventions reported in US and European studies with regard to changes on psychological measures. Moreover, many patients also reported (on the final day of the intervention) a decrease in seizure frequency. All patients reported that participating in the intervention was a positive experience. Also, all but one patient referred that the participation in the group would have a positive impact on their quality of life. CONCLUSIONS: Psychoeducational interventions appear to have had positive results in Argentinian patients with PNES. This is initial step in the design of empirically based psychoeducational/supportive initiatives for patients in South America.
