Development and early validation of a patient-reported outcome measure to assess sleep amongst people experiencing problems with alcohol or other drugs
To develop a patient reported outcome measure to assess sleep amongst people experiencing problems with alcohol or other drugs.
Item development included secondary analyses of qualitative interviews with drug/alcohol users in residential treatment, a review of validated sleep measures, focus groups with drug/alcohol users in residential treatment, and feedback from drug/alcohol users recruited from community and residential settings. An initial version of the measure was completed by 549 current and former drug/alcohol users (442 in person [IP] and 107 online [OL]). Analyses comprised classical test theory methods, exploratory and confirmatory factor analysis, measurement invariance assessment, and item response theory (IRT).
The initial measure (30 items) had good content and face validity, and was named the Substance Use Sleep Scale (SUSS) by addiction service users. After 7 items were removed due to low item-factor loadings, 2 factors were retained and labelled: 'Mind and Body Sleep Problems' (14 items) and 'Substance Related Sleep Problems' (9 items). Measurement invariance was confirmed with respect to gender, age, and administration format. IRT (information) and classical test theory (internal consistency, stability) indicated measure reliability. Standard parametric and non-parametric techniques supported convergent and discriminant validity.
SUSS is an easy-to-complete patient reported outcome measure of sleep for people with drug/alcohol problems. It can be used by those concerned about their own sleep, and by treatment providers and researchers seeking to better understand, assess, and potentially treat sleep difficulties amongst this population. Further validity testing with larger and more diverse samples is now required.
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 October 2018.
All research outputs
#10,238,991
of 34,376,207 outputs
Outputs from Sleep
#3,258
of 6,053 outputs
Outputs of similar age
#147,182
of 497,790 outputs
Outputs of similar age from Sleep
#33
of 50 outputs
Altmetric has tracked 34,376,207 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
So far Altmetric has tracked 6,053 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 33.9. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 497,790 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
