Abstract

= -.455). Factorial invariance suggests that the structure of the SWJLS measures the same construct (satisfaction with work-life) in both female and male workers. Moreover, IRT analysis suggests that higher levels of work-life satisfaction are needed to choose the upper response options, while a very low level of work-life satisfaction is required to increase the likelihood of choosing the lower response options. In this sense, the SWJLS is useful and reliable, especially for identifying people with low levels of job satisfaction. These findings support the validity of the SWJLS and indicate that the Portuguese version is a brief instrument with good psychometric characteristics for measuring work-life satisfaction.
