From this point of view, the present research had the objective of analysing the effects of work regimes on the mental health of petroleum operators of Petrobr?s. The sample totaled 144 subjects, corresponding to 27% of the work population. The mental health of the participants was evaluated using the following instruments of measurement: QSG-12, Scale of self-esteem, Scale of Positive and Negative Affections and the Scale of Valuable Attributes of IMST, each representing an empirical factor used to indicate and measure the five dimensions of mental health. The subjects perceptions of their work regime and the rest of their conditions of work were evaluated using scales of descriptive attributes of IMST, by applying a semi-structured questionnaire and by use of interviews. A socio-demographic file was used to collect information related to the biographical and socio-occupational profile of the worker sample. The answers to the questionnaire were inserted into the data bank of SPSS (Statistical Package for Social Science), for statistical analysis, and the interviews were analised based on the technique of Contents Analysis recommended by Bardin (1995). The main results revealed that one third of the worker sample were tense; however, the mental health of the majority was preserved. Cluster Analysis applied to the group of seven factors which measured the five dimensions of mental health identified four profiles of psychological well-being shared between members of the sample. It was observed that the people working in the system of Continuous Shift Alternation (TIR) and in the system of Pre-advising tended to present balanced and satisfactory profiles, while the ones which worked in the Administrative Field tended to present anxious and oscillating profiles, and thus were more affected psychologically. These were also the ones that also perceived the more negative aspects of their laborious conditions (reduced chances of self-improvement, physically stressful and financial resources below expectations with which to supply family and personal necessities. In agreement with the ecological model formulated by Warr (1987), the present study concluded that the positive and negative effects on the psychological well-being tended to occur as a consequence of the perceptions the petrol operators developed to face their work conditions / A import?ncia de identificar as conseq??ncias dos hor?rios de trabalho para os indiv?duos inseridos na atual sociedade 24 horas, tem sido amplamente reconhecida dentro da Psicologia Organizacional e do Trabalho. Partilhando desse interesse, a presente pesquisa objetivou analisar os efeitos dos regimes de trabalho sobre a sa?de mental dos operadores de petr?leo da Petrobr?s. A amostra totalizou 144 sujeitos, correspondendo a 27% da popula??o. A sa?de mental dos participantes foi avaliada por meio dos seguintes instrumentos: QSG-12, Escala de Auto-estima, Escala de Afetos Positivos e Negativos e a escala de atributos valorativos do IMST, sendo cada fator emp?rico usado como indicador para medir cinco dimens?es da sa?de mental. A percep??o sobre os regimes e demais condi??es de trabalho foram avaliadas por meio das escalas de atributos descritivos do IMST, de um question?rio semi-estruturado e de entrevistas. Tamb?m se usou uma ficha s?cio-demogr?fica para colher informa??es relativas ao perfil biogr?fico e s?cio-ocupacional da amostra. As respostas aos question?rios foram digitadas na forma de banco de dados do SPSS (Statistical Package for Social Science for Windows), por meio do qual se procedeu com as an?lises estat?sticas, e as entrevistas foram analisadas com base na t?cnica de an?lise de conte?do recomendada por Bardin (1995). Os principais resultados revelam que um ter?o da amostra se encontra tensa, contudo a sa?de mental est? preservada para a maioria. A an?lise de cluster aplicada ao conjunto dos sete fatores que mediram as cinco dimens?es de sa?de mental identificou quatro perfis de Bem-estar Psicol?gico compartilhados entre a amostra. Observou-se que o pessoal engajado em regimes de Turno Ininterrupto de Revezamento (TIR) e de Sobreaviso tende a apresentar perfis Equilibrado e Satisfat?rio, enquanto os que trabalham em regimes Administrativo de Campo e Administrativo tendem a apresentar perfis Ansioso e Oscilante, sendo estes ?ltimos os mais afetados psiquicamente e que percebem mais negativamente as condi??es laborais (chances reduzidas de aperfei?oamento, fisicamente desgastantes e recursos financeiros reduzidos ou abaixo do esperado para suprir as necessidades pessoais e familiares). Em conformidade com o modelo ecol?gico formulado por Warr (1987), o presente estudo concluiu que os efeitos positivos ou negativos no bem-estar psicol?gico tendem a acontecer como conseq??ncia da percep??o que os operadores desenvolvem frente ?s condi??es de trabalho
