Abstract
ObjectivesThis study aims to measure the level of validity and reliability of PDSS-2 in Parkinson's disease with sleep disorders. MethodsThe study was conducted on Parkinson's patients with sleep disorders that the inclusion criteria are women or men aged >40 years, diagnosed with Parkinson's disease. The PDSS-2 score is used to assess sleep disorders. Assessment is done twice with an interval of examination 10min. Then measure the Pearson correlation test between two examinations (validity test) and reliability by calculating the Cronbach's alpha PDSS-2 value, and inter-rater reliability to determine internal consistency. ResultsThe study subjects were 15 PD patients, range age between 51 and 75 years (63.0±8.95). Consist of 11 men and four women. The validity test value on the two examinations showed 9 of 15 items (60% validity) and 7 of 15 items (46.6% validity). The second reliability test was declared reliable with each value of Cronbach alpha 0.833 and 0.644 (r table value=0.60), with inter-rater reliability value is 0.706. ConclusionThe PDSS-2 score is reliable in assessing sleep disorders in Parkinson's disease with internal consistency 0.706, and the validity value is 80%.
