Purpose: The purpose of this study is to investigate whether self-awareness, which is associated with general well-being and positive life outcomes, is also of specific benefit in the workplace. The authors tested the relationship between self-awareness and job-related well-being, and evaluated two different interventions designed to improve dispositional self-awareness at work. Design/methodology/approach: Full-time employees took part in these training interventions and completed questionnaires using a switching-replications design. Questionnaires measured dispositional self-attentiveness (reflection and rumination) and job well-being (satisfaction, enthusiasm and contentment) at three time points over a period of six weeks. Statistical analyses were complemented with qualitative analysis of reported impacts. Findings: Self-awareness was positively associated with job-related well-being and was improved by training. Employees reported gaining a greater appreciation of diversity, improved communication with colleagues and increased confidence. Research limitations/implications: Sample size limited the extent to which the relatively weak relationships between the concepts could be identified. Practical implications: Self-awareness is demonstrated to be of value at work, associated with higher well-being and improvements in several positive occupational outcomes. The self-awareness training is more likely to result in active work-based improvements than in reflective changes. Originality/value: Dispositional self-awareness is shown to be subject to change through training. The study demonstrates the value of self-awareness at work and identifies a range of related work outcomes.
