ABSTRACT
Resumen. El objetivo de este estudio fue analizar la validez factorial del modelo psicométrico del Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT) en una muestra multiocupacional de trabajadores colombianos. Se hipotetizó un modelo de cuatro factores con base en la estructura factorial del modelo original. Los participantes fueron 153 trabajadores que desempeñan diversos roles en empresas ubicadas en Colombia. Se aplicó el CESQT que se compone de cuatro dimensiones: Ilusión por el trabajo (5 ítems), Desgaste psíquico (4 ítems), Indolencia (6 ítems) y Culpa (5 ítems). Las propiedades psicométricas fueron examinadas mediante Análisis factorial confirmatorio (AFC) y fiabilidad (alfa de Cronbach). Los ítems presentaron valores estadísticos y psicométricos adecuados, así como las escalas. El modelo presentó un ajuste aceptable a los datos: GFI = .858, RMSEA = .066 (.051.079), NNFI = .913, CFI = .927. La consistencia interna fue alta para todas las escalas del instrumento (a = .79 hasta a = .87). Los resultados indican que el CESQT es un instrumento con suficiente validez psicométrica para evaluar el síndrome de quemarse por el trabajo (SQT) en el contexto cultural colombiano.
Abstract The purpose of this paper was to assess the factor structure of the Spanish Burnout Inventory (SBI) in a multi-occupational sample of Colombian workers. On the basis of previous results and the factor structure of the instrument, a four-factor model was hypothesized. The sample consisted of 153 Colombian workers from different occupational sectors. The SBI was applied. This instrument is composed of 20 items distributed in four dimensions: Enthusiasm toward the job (5 items), Psychological exhaustion (4 items), Indolence (6 items), and Guilt (5 items). The psychometric properties were examined by confirmatory factor analysis (CFA) and the reliability was tested by Cronbach's alpha. The items presented adequate statistical and psychometric values, as well as the scales. The model presented an acceptable fit to the data: GFI = .858, RMSEA = .066(051-079), NNFI = .913, CFI = .927. Reliability was adequate for all scales (a = .79 to a = .87). The results indicate that the SBI is an instrument with psychometric validity to assess the burnout in the Colombian cultural context.

Objective: To examine oral health condition of the military officers and soldiers before and after military field training. Methods: After technical training,investigators went to a military field training place to carry out the oral health examination at the beginning and at the time of ending,respectively. Basic examinations included oral ulcer conditions,sulcus bleeding index(SBI) and plaque index(PLI). Results: 145 military officers and soldiers were consistent with inclusion criteria. Compared with those before field training,at the end of training the incidence of oral ulcer was significantly increased(P ＜ 0. 05); SBI of 16,26,36 and 46 was significantly higher(P ＜ 0. 05); PLI of 16,26,36 and 46 was significantly higher(P ＜ 0. 05). Conclusion: Oral health condition of military officers and soldiers may become poor during field training,corresponding oral health care should be emphasized.
ABSTRACT
O objetivo deste estudo foi explorar a estrutura fatorial e a consistência interna da adaptação ao português do "Spanish Burnout Inventory" (SBI) numa amostra composta por 245 policiais de diversos esquadrões da região de Lisboa. Realizou-se uma análise fatorial exploratória (AFE), de onde foram extraídos 4 fatores com autovalor > 1, que reproduziram a distribuição dos itens da versão original: no primeiro fator ficaram agrupados os itens da subescala Entusiasmo pelo Trabalho, no segundo os itens da subescala Culpa, no terceiro os itens da subescala Indolência, sendo que os itens da subescala Desgaste Psíquico se distribuíram pelo quarto fator. Todas as subescalas do SBI alcançaram valores alfa de Cronbach superiores a 0,70. Os resultados sugerem que a versão portuguesa do SBI é um instrumento valido e fiável para avaliar a síndrome do burnout em policiais portugueses.
This study was designed to assess the factor structure and the internal consistency of the Portuguese adaptation of the "Spanish Burnout Inventory" (SBI) in a sample of 245 Portuguese police officers working in Lisbon. Using an Exploratory Factor Analysis (EFA), 4 factors were extracted with eigenvalue > 1, reproducing the original model: the first factor was constituted by the items of "enthusiasm toward the job", the second factor was constituted by the items of "guilt", the third factor was constituted by the items of "indolence", and the fourth factor was constituted by the items of "psychological exhaustion". Internal consistency values for all subscales showed values of Cronbach's alpha higher than .70. The results suggest that the Portuguese adaptation of the SBI is an adequate instrument to assess burnout in Portuguese police officers.

@#ObjectiveTo investigate the neuropsychological impairments and risk factors that caused cognitive disturbance in patients with silent brain infarction (SBI). Methods36 SBI subjects and 25 normal controls were compared on a comprehensive neuropsychological test battery. Logistic regression was used to analysis the risk factors. ResultsThe SBI group scored lower on the visual retention test (VRT), the WAIS RC full scale IQ, standard scores of the perceptual organization factor and memory/attention factors than did the control group. The score of self rating depression scale (SDS) was higher in SBI group. Hypertension and leukoaraiosis (LA) were correlates of cognitive impairment in logistic regression analyses. Conclusions SBI has some degree of neuropsychological impairment, especially deficits of visuospatial ability, disturbance of perceptual organization, memory and attention, and some degree of depression. Hypertension and LA independently contribute to the risk factors of cognitive disturbance.
