Defining the complexities of an occupational pattern-A concept analysis and theoretical validation.

Background: The concept of an occupational pattern in occupational therapy and occupational science has evolved with varying definitions, ranging from activity patterns to patterns of daily occupation.

Aims: This study aimed to explore the concept of occupational pattern, develop an updated definition of the concept, and theoretically validate the concept's definition.

Method: Walker and Avant's concept analysis method was used, where both theoretical frameworks and peer-reviewed scientific literature were searched and synthesized to clarify and define the concept. Furthermore, seven occupational therapists theoretically validated the concept.

Findings: The analysis included forty-nine references from various research contexts and theoretical perspectives. The synthesis yielded a conceptualization of the concept of occupational pattern, outlining it into three overarching categories: 'content in an individual's occupational pattern', 'designing an occupational pattern', and 'balancing the occupational pattern'.

Implications: An updated operational definition of the multifaceted concept of an occupational pattern now exists, with practical implications for enhancing the education of occupational therapy students and guiding the utilization of the concept. Moreover, it holds significance for instrument development and outcome measurement in research; especially in lifestyle intervention studies within the field of occupational therapy.
