Work-life balance/imbalance has been increasingly recognized as being critically involved in poor adjustment in occupational settings. Little has been forthcoming on cognitive functioning among those with work-life imbalance. This study was to explore the rate of work-life imbalance, variation in neuropsychological functioning. The relationship between mood and work-life balance was also explored. The target population in this study are Omani nationals who were referred for psychometric evaluation. The study employs neuropsychology measures tapping into attention and concentration, learning and remembering, processing speed, and executive functioning. Subjective measures of cognitive decline and affective ranges were also explored. A total of 168 subjects (75.3% of the responders) were considered to be at a work-life imbalance. Multivariate analysis showed that demographic and neuropsychological variables were significant risk factors for work-life imbalance including age and the presence of anxiety disorder. Furthermore, participants indicating work-life imbalance were more likely to report cognitive decline on indices of attention and concentration and learning and remembering. This study reveals that individuals with work-life imbalance might dent the integrity of cognition including attention and concentration, learning and remembering, executive functioning, and endorsed caseness for anxiety.
