Abstract Background and objectives Caregivers of progressive supranuclear palsy ( PSP) patients frequently show significant distress. The Parkinsonism Carers quality of life (QoL) (PQoL Carer) is a valid tool evaluating the effect of PSP on caregivers' QoL . Main aim of the present study was to develop a short version of the PQoL Carer, named PSP ‐ ShoQoL Carer. Methods PQoL Carer was administered within the PSP ‐ NET . Participants underwent clinical, motor, cognitive, and behavioral evaluations. Results Data from 344 participants were included. The final PSP ‐ ShoQoL Carer included eight items. The internal consistency was high (Cronbach's α = 0.867) and PSP ‐ ShoQoL Carer showed also good acceptability, reliability, and validity. The PSP ‐ ShoQoL Carer showed a significant correlation with caregivers' standard measures of QoL and with patients' motor, cognitive, and behavioral characteristics, such as neuropsychiatric symptoms. Finally, PSP ‐ ShoQoL Carer showed an appropriate sensitivity to change over 6‐month follow up. Conclusions PSP ‐ ShoQoL Carer is a reliable and valid time‐saving tool for the assessment of caregivers' QoL in PSP .
