Informal caregivers often provide transfer assistance to individuals with disabilities; however, repeated transfers are associated with a high risk of musculoskeletal pain and injury, and training and education around transfers is minimal. The purpose of this study was to develop and assess the content validity of a new tool, the Caregiver Assisted Transfer Technique Instrument (CATT), which could be used to provide an objective indicator of transfer performance. Item importance, clarity, and appropriateness of responses were rated on a five-point Likert scale by clinicians (  = 15), informal caregivers (  = 10), and individuals with spinal cord injury (  = 5). The content validity index and modified Kappa of each item was calculated. Participants also provided qualitative feedback on item content. In general, items were rated favorably for their importance (4.47 to 5.00), clarity (4.33 to 4.90), and appropriateness of responses (4.38 to 4.90), and most items had excellent content validity (k* ≥ 0.75). Feedback from participants led to the creation of two versions of the CATT: one for manual lifting techniques (CATT-M) and one for transfers performed via lift-based technologies (CATT-L). Future work will focus on establishing the reliability and validity of the CATT as well as developing training and education interventions surrounding assisted transfers.
