Background The concept of occupational identity has become an important focus within occupational science and occupational therapy, drawing both recognition and inquiry. Even if the concept is highly relevant for understanding the occupational nature of human beings, ambiguity regarding the identification and application of occupational identity exists. Aim This analysis aimed to clarify the concept of occupational identity by examining its current use and application within occupational therapy. Materials and methods Walker and Avant's method for concept analysis was utilized to clarify the concept of occupational identity. Results Analysis resulted in three distinct categories of use: occupational identity construction, occupational identity discrepancy and occupational identity disruption, described contextually in terms of the self being, the self being and doing, and the self being and doing with others. Conclusions Findings validated the significant connection between occupation and identity through doing, being and future becoming. Also uncovered were considerable connections to belonging. Significance Occupational identity encompassed complex connections comprising both individual and collective components. Personally meaningful expression and connection were of particular significance to occupational identity as discrepancies or disruption of meaningful connections had negative implications for occupational engagement.
