title: Self-rating of daily time management in children: psychometric properties of the Time-S.
abstract: BACKGROUND
  Impaired ability to manage time has been shown in several diagnoses common in childhood. Impaired ability involves activities and participation domain (daily time management, DTM) and body function and structure domain (time-processing ability, TPA). DTM needs to be evaluated from an individual's own perspective. To date, there has been a lack of self-rating instruments for children that focus on DTM.
  
  
  OBJECTIVE
  The aim of this study is to describe psychometric properties of Time-S when used in children aged 10-17 years with a diagnosis of ADHD, Autism, CP or mild ID. Further, to test whether TPA correlates with self-rated DTM.
  
  
  METHODS
  Eighty-three children aged 10-17 years participated in the study. Rasch analysis was used to assess psychometric properties. Correlation analysis was performed between Time-S and a measure of TPA.
  
  
  RESULTS
  The 21 items of the Time-S questionnaire fit into a unitary construct measuring self-perceived daily management of an individual's time. A non-significant, small correlation was found between TPA and DTM.
  
  
  CONCLUSIONS
  The results indicate good psychometric properties for the questionnaire. The questionnaire is potentially useful in intervention planning and evaluation.
