abstract = {To characterize sleep problems and to compare subjective
and objective assessments in breast cancer patients starting
neoadjuvant chemotherapy.Sleep characteristics of 54 breast
cancer patients starting neoadjuvant chemotherapy were
analyzed. Subjective sleep characteristics were assessed
with the Pittsburgh Sleep Quality Index (PSQI) and objective
sleep measurements with an accelerometer (ActiGraph
wGT3X-BT) worn on the wrist for 7 consecutive days.According
to the common PSQI cut-off of 8, 10 $(18.87\%)$ of the
patients were poor sleepers. ActiGraph measures did not
mirror this classification as values for poor, and good
sleepers did not differ significantly. Overall, Bland-Altman
plots illustrated higher ActiGraph values for sleep
efficiency and effective sleep time and lower values for
sleep latency, compared with PSQI. For total sleep time,
less disagreement between both measures was observed.
Actigraphy was limited in precise identification of sleep
begin and sleep latency but provided supplementary
information about number and minutes of awakenings during
the night.Subjective and objective measurement methods
differed substantially in various parameters, with
limitations in both methods. A combination of both methods
might be most promising.Clinicaltrials.gov: NCT02999074.},
