title: Effect on motivation, perceived competence, and activation after participation in the ''Ready to Act'' programme for people with screen-detected dysglycaemia: a 1-year randomised controlled trial, Addition-DK.
abstract: OBJECTIVE
  To investigate the reach of the ''Ready to Act'' programme and the 1-year effects on psychological determinants of healthy behaviour: motivation, perceived competence, and activation level.
  
  
  METHODS
  A total of 509 adults with dysglycaemia were recruited from general practioners (GPs) in the intensive arm of the Danish Anglo-Danish-Dutch Study of Intensive Treatment in People with Screen-Detected Diabetes in Primary Care (ADDITION) study, a type 2 diabetes screening programme. The participants were randomised to the ''Ready to Act'' programme added on top of GP care (n = 322) or to GP care (n = 187). The core components of the programme were motivation, action experience, informed decision-making, and social involvement conducted in two one-to-one sessions and eight group-meetings (18 hours). The reach of the programme was measured by the proportion of people who signed up. Outcomes were changes in treatment motivation (Treatment Self-Regulation Questionnaire, TSRQ), perceived competence (Perceived Competence Scale, PCS), and activation in chronic care (Patient Activation Measure, PAM). Effect size was the difference between 1-year changes in the randomisation groups analysed by intention-to-treat.
  
  
  RESULTS
  A total of 142 (44%) of 322 signed up and 123 (87%) of these completed. At 1 year, the difference in autonomous motivation for behavioural treatment (TSRQ) between the randomisation groups was 1.0 (95% CI 0.1 to 2.0), and the difference in perceived competence changes in healthy diet (PCS-d) was 1.5 (95% CI 0.2 to 2.7). No differences were observed for activation (PAM) between the groups. Subgroup analysis revealed men to benefit more from the intervention than women.
  
  
  CONCLUSIONS
  The programme is a promising health-promoting component in prevention and care for people with screen-detected dysglycaemia, as it attracted four of 10 people and had effects on motivation and perceived competence.
