Perceived influences on reducing prolonged sitting in police staff: a qualitative investigation using the Theoretical Domains Framework and COM-B model

Abstract

Background: Workplace interventions have shown promise for reducing sitting in office workers. Police office staff remain an understudied population group that work within a disciplined organisation with distinctive work tasks around public safety, potentially affecting their capability, opportunity, and motivation to change sitting behaviour. This study aimed to assess the perceived influences on reducing workplace sitting in non-operational, desk-based police staff in order to derive theoretical determinants for behaviour change. Methods: Ten police staff from a single police force in Bedfordshire, England [eight female; 39.5±11.5 years] took part in face-to-face semi-structured interviews lasting 46±11 minutes on average. Thematic analysis identified key themes which were then mapped onto the Theoretical Domains Framework (TDF) and linked to the Capability, Opportunity, Motivation-Behaviour (COM-B) model. Results: Seven themes were identified: ‘Work tasks are seated’, ‘Social norm is to sit’, ‘Belief in ability to regulate behaviour’, ‘Knowledge of health risks’, ‘Organisational support’, ‘Impact on productivity’, and ‘Perceived autonomy for sitting reduction’. Conclusions: Awareness of behaviour and health impacts (Capability), social and physical support to sit less (Opportunity), and habit formation techniques (Motivation) are recommended considerations in sitting reduction workplace interventions for police staff.
