  1. NA not assessed
  2. aAn acceptable level of inter-rater reliability (κ = .60) was found for the system integration variable
  3. bItems: a) Is the aim of the inter-organisational arrangement explicated? b) Are the solution(s) of the inter-organisational arrangement explicated? c) Are the chances of the inter-organisational arrangement explicated? and d) Is the form for the inter-organisational arrangement explicated? Single-factor solution, with factor loadings ranging from: 0.798 to 0.832
  4. cItems: a) Leadership is being demonstrated. b) Are roles and tasks of the team clear? c) Are final clinical goals agreed upon? d) Do information systems (ICT) support the team’s functionality? e) Are there agreements about the interdisciplinary care delivery? f) Are outcomes for the patients clear? g) Are outcomes for the professionals clear? h) Are outcomes for the community clear. i) Is the interdisciplinary approach applicable elsewhere. j) Is the effectiveness of the inter-professional team clear? Single-factor solution, with factor loadings ranging from: 0.348 to 0.784
