Abstract(s)
A carga mental, pode ser considerada um risco psicossocial, que afeta negativamente a saúde
física e mental dos trabalhadores. De forma a colmatar este risco, é necessária a implementação
de medidas em que o empregador é a chave, permitindo melhorias na saúde e no bem-estar
laboral dos trabalhadores. A recolha de dados feita respeitou todos os pressupostos éticos de uma
investigação e procurou dar resposta ao objetivo geral: contribuir para a adaptação e validação do
instrumento Carga Mental Questionaire (CarMen-Q) numa amostra de trabalhadores
portugueses. Especificamente, pretendeu-se avaliar as propriedades psicométricas do CarMen-Q,
testando a validade convergente através das dimensões exigências quantitativas, exigências
cognitivas, exigências emocionais e ritmo de trabalho do Copenhagen Psychosocial
Questionnaire (COPSOQ- II). A validade de critério foi examinada através da relação que as
dimensões do CarMen-Q estabeleceram com os conceitos de satisfação no trabalho, engagement
no trabalho, exaustão emocional, performance no trabalho, stresse, clima de segurança
psicossocial e caraterísticas individuais (i.e., traços de personalidade). Por último, a fidelidade
foi calculada através de dois coeficientes, alfa de Cronbach e Composite Reliability. Verificou-se
a existência de validade fatorial, quanto à validade convergente apenas para as dimensões
exigências emocionais e temporais atingiram valores de Average Variance Extracted (AVE)
iguais ou superiores a .50. No que diz respeito à validade de critério, a carga mental estabeleceu
uma correlação negativa e estatisticamente significativa com o clima de segurança psicossocial,
conformidade com a segurança e satisfação no trabalho; e uma correlação positiva e
estatisticamente significativa com a exaustão emocional, o stresse, a ansiedade, a depressão, o
neuroticismo e a abertura à experiência. Por último, os valores de fiabilidade para as dimensões e
constructo de carga mental foram superiores a .70, demonstrando que esta é uma ferramenta
fiável.
Mental workload can be considered a psychosocial risk, which negatively affects the physical and mental health of workers. To address this risk, it is necessary to implement measures in which the employer is the key, allowing for improvements in workers' health and well-being at work. Data collection followed all the ethical assumptions of a research study and tried to answer the general objective: to contribute to the adaptation and validation of the Carga Mental Questionnaire (CarMen-Q) in a sample of Portuguese workers. Specifically, we aimed at assessing the psychometric properties of the CarMen-Q, testing the convergent validity through the dimensions quantitative demands, cognitive demands, emotional demands, and pace of work of the Copenhagen Psychosocial Questionnaire (COPSOQ- II). Criterion validity was examined through the relationship that the CarMen-Q dimensions established with the concepts of job satisfaction, work engagement, emotional exhaustion, job performance, stress, psychosocial safety climate, and individual characteristics (i.e., personality traits). Finally, reliability was calculated through two coefficients, Cronbach's alpha and Composite Reliability. It was verified the existence of factor validity, as for convergent validity only for the emotional and temporal demands dimensions reached Average Variance Extracted (AVE) values equal to or greater than .50. With regard to criterion validity, mental workload established a negative and statistically significant correlation with psychosocial safety climate, safety compliance, and job satisfaction; and a positive and statistically significant correlation with emotional exhaustion, stress, anxiety, depression, neuroticism, and openness to experience. Finally, the reliability values for the dimensions and construct of mental workload were greater than .70, demonstrating that this is a reliable tool.
