Psychometric properties of the Clinical Sustainability Assessment Tool (CSAT) short form across three research centers evaluating effectiveness and implementation of a cancer symptom surveillance and management intervention

The CSAT Short is recommended to assess sustainability in oncology settings, though users should be cautious when comparing scores across different healthcare systems. Tests of invariance were nonsignificant except for variance by Research Center. Despite some items exhibiting suboptimal fit in mIRT, the overall model fit and reliability were strong. This study advances our understanding of sustainability measurement and the applicability of the CSAT Short across implementation settings and respondents.
