Thirty‐two participated in a cognitive interview, and 337 completed a questionnaire booklet. Interviews were used to develop the TRANSITION‐Q. Rasch measurement theory (RMT) analysis was used to identify items that represent the best indicators of self‐management skills. Traditional psychometric tests of measurement performance were also conducted.</p> </sec> <sec id="cch12207-sec-0004" sec-type="section"> <title>Results</title> <p>The response rate was 92% (32/32 cognitive; 337/371 field test). RMT analysis resulted in a 14‐item scale with three response options. The overall fit of the observed data to that expected by the Rasch model was non‐significant, providing support that this new scale measured a unidimensional construct. Other tests supported the scale as scientifically sound, e.g. Person Separation Index = 0.82; good item fit statistics; no differential item function by age or gender; low residual correlations between items; Cronbach's alpha = 0.85; test‐retest reliability = 0.90; and tests of construct validity that showed, as hypothesized, fewer skills in younger participants and in participants who required assistance to complete the scale. Finally, participants who agreed they are ready to transfer to adult healthcare reported higher TRANSITION‐Q scores than did participants who disagreed.</p> </sec> <sec id="cch12207-sec-0005" sec-type="section"> <title>Conclusions</title> <p>The TRANSITION‐Q is a short, clinically meaningful and psychometrically sound scale. This generic scale can be used in research and in paediatric and adolescent clinics to help evaluate readiness for transition.</p> </sec> </abstract>
