Using Theoretical Domains Framework for Exploring Appropriate Sitting Posture Determinants Among Office Workers: A Content Analysis Study

Abstract

Background: Sedentary occupations frequently expose employees to prolonged periods with poor posture, which has been considered as the cause of musculoskeletal disorder. Objectives: The study set out to identify the related factors of a taking healthy sitting posture in office workers. Methods: This qualitative study aimed to use the theoretical domains framework (TDF) to investigate perceived determinants to taking a proper sitting posture in office workers. Semi-structured interviews with 25 office workers according to purposive sampling was conducted with a convenience sample of university office workers in Iran. Recorded interviews were transcribed into MAXQDA version 10. Directed content analysis and framework analysis were used for drawing the 12 domains of the TDF. Results: Explored themes were mapped onto the TDF domains, including skills, knowledge, behavioral regulation, goals, environmental context and resources, social influences, beliefs about capability, intentions, emotion, beliefs about consequences, memory, and attention and reinforcement. Conclusions: This study is a theoretical starting point in making structured interventions to change improper sitting posture among office workers. Also, the identified factors provide organizational managers with a wide list of factors by which they can encourage their employees to use proper postures in the workplace, leading to a significant reduction in job absenteeism and insurance fees associated with health problems. In addition, this study enriches the literature by providing additional empirical evidence for the TDF theory.
