OBJECTIVE: To perform a cross-cultural adaptation of the Portuguese version of the Maslach Burnout Inventory for students (MBI-SS), and investigate its reliability, validity and cross-cultural invariance. METHODS:The face validity involved the participation of a multidisciplinary team. Content validity was performed. The Portuguese version was completed in 2009, on the internet, by 958 Brazilian and 556 Portuguese university students from the urban area. Confi rmatory factor analysis was carried out using as fi t indices: the  2 /df, the Comparative Fit Index (CFI), the Goodness of Fit Index (GFI) and the Root Mean Square Error of Approximation (RMSEA). To verify the stability of the factor solution according to the original English version, crossvalidation was performed in 2/3 of the total sample and replicated in the remaining 1/3. Convergent validity was estimated by the average variance extracted and composite reliability. The discriminant validity was assessed, and the internal consistency was estimated by the Cronbach's alpha coeffi cient. Concurrent validity was estimated by the correlational analysis of the mean scores of the Portuguese version and the Copenhagen Burnout Inventory, and the divergent validity was compared to the Beck Depression Inventory. The invariance of the model between the Brazilian and the Portuguese samples was assessed. RESULTS:The three-factor model of Exhaustion, Disengagement and Effi cacy showed good fi t ( 2 /df = 8.498, CFI = 0.916, GFI = 0.902, RMSEA = 0.086). The factor structure was stable (:  CONCLUSIONS:The Portuguese version of the Maslach Burnout Inventory for students showed adequate reliability and validity, but its factor structure was not invariant between the countries, indicating the absence of cross-cultural stability.

“…The invariance test was conducted imposing equality restrictions to the factorial weights of the two groups, being the statistical test the difference between the χ 2 of the model fixed factor weights and the model with equal factor weights. When the hypothesis of factorial invariance was accepted, the analysis of the invariance of the correlations between factors was performed, and finally the invariance of specific factors (residues; Kaplan, 2000). Then, the same procedure was made to assess the invariance of the factor solution obtained in the Portuguese sample and in the sample Brazilian.…”

ResumoRealizou-se adaptação cultural do Inventário de Oldenburg para estudantes (OLBI-S) em português e estimou-se sua confiabilidade e validade. O OLBI-S foi preenchido por 958 estudantes universitários brasileiros e 602 portugueses. O modelo fatorial original apresentou ajustamento adequado mas foram removidos dois itens com confiabilidade individual baixa (λ<0,5). A nova estrutura apresentou bom ajustamento a 2/3 da amostra total sendo invariante no 1/3 restante da amostra. Verificou-se baixa consistência interna e validade convergente, confiabilidade compósita aceitável, boa validade discriminante, concorrente e divergente. O OLBI-S não foi invariante nas amostras de Brasil e Portugal. O OLBI-S apresentou limitações e ausência de validade transcultural nas amostras estudadas. Palavras-chave: Burnout, estudantes universitários, avaliação, Psicometria. AbstractThe Oldenburg Burnout Inventory for college students (OLBI-S) was adapted to Brazilian Portuguese and its reliability and validity were measured in a sample of both Brazilian (n=958) and Portuguese (n=602) college students. The confirmatory factor analysis of the OLBI-S showed good fit but two items were removed since they lacked individual reliability (λ<.50). The new structure showed good fit to 2/3 of the test sample and was invariant to the other 1/3 of the total sample. Convergent validity and internal consistency were low, but discriminant, concurrent and divergent validity were good. The OLBI-S was not invariant in the Brazilian and Portuguese samples. The adapted OLBI-S did not show cross-cultural validity. Keywords: Burnout, college students, evaluation, Psychometrics.The burnout syndrome was initially defined as a psychological condition related to work in help professions and that require interaction with others, and is characterized by high levels of emotional exhaustion, high disbelief in the function and low professional accomplishment. Initially, it was believed that the burnout syndrome affected only professionals with extensive human interaction as social workers, nurses, doctors and psychologists. However, currently it is known that the burnout syndrome exceeds care services, since the stressors that can initiate it may be present in any workplace (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). More recently, higher education students have been identified in the literature as a vulnerable group for the development of Burnout (Balogun, Helgemoe, Pellegrini, & Hoeberlein, 1995;Marôco & Tecedeiro, 2009;Marôco, Tecedeiro, Martins, & Meireles, 2008;Martinez, Pinto, & Silva, 2000;Schaufeli, Martinez, Pinto, Salanova, & Bakker, 2002) due to socio-economic pressures, concerns about their professional future, relationships with peers and teachers, tests and papers to which they are constantly exposed, and therefore constitute a risk population to be studied.Carlotto and Câmara (2006), Dyrbye et al. (2010), Martinez et al. (2000 and Salanova, Schaufeli, Martinez, and Breso (2010) and emphasize that early detection of symptomatic significant l...

Using music as a signal for biofeedback

Studies on the potential benefits of conveying biofeedback stimulus using a musical signal have appeared in recent years with the intent of harnessing the strong effects that music listening may have on subjects. While results are encouraging, the fundamental question has yet to be addressed, of how combined music and biofeedback compares to the already established use of either of these elements separately. This experiment, involving young adults (N = 24), compared the effectiveness at modulating participants' states of physiological arousal of each of the following conditions: A) listening to pre-recorded music, B) sonification biofeedback of the heart rate, and C) an algorithmically modulated musical feedback signal conveying the subject's heart rate. Our hypothesis was that each of the conditions (A), (B) and (C) would differ from the other two in the extent to which it enables participants to increase and decrease their state of physiological arousal, with (C) being more effective than (B), and both more than (A). Several physiological measures and qualitative responses were recorded and analyzed. Results show that using musical biofeedback allowed participants to modulate their state of physiological arousal at least equally well as sonification biofeedback, and much better than just listening to music, as reflected in their heart rate measurements, controlling for respiration-rate. Our findings indicate that the known effects of music in modulating arousal can therefore be beneficially harnessed when designing a biofeedback protocol.
