Background: The Powered Mobility Device Autonomy Residential Screen (PoMoDARS) is a new tool to enable clinicians to screen resident capacity and performance skills for powered mobility device (PMD) use in residential aged care settings. The PoMoDARS is context specific, time efficient and promotes resident autonomy and safety.

Aims: To (i) undertake initial face and content validation of the PoMoDARS, and (ii) use the research findings to make any modifications.

Methods: A mixed-methods study design, underpinned by Classical Test Theory. Eight clinicians completed 20 PoMoDARS screens and provided both quantitative and qualitative feedback on item importance and ease of use within a formal interview.

Results: Initial face and content validity of the PoMoDARS were supported, with small modifications made to item descriptors and instructions.

Conclusions: The PoMoDARS has been developed for use in residential aged care settings to screen resident PMD use. While initial validation has been undertaken, further studies to determine the reliability of the tool and continue the validation process are required.

Significance: Older adults in residential aged care facilities benefit greatly from the autonomy gained through PMD use. The PoMoDARS promotes collaboration between occupational therapists, nurses, and the wider team to support residents and safe PMD use.
