Alcohol Behavioral Couple Therapy (ABCT) is an efficacious treatment for alcohol use disorders. Coding treatment integrity can shed light on the active ingredients of ABCT, but there are no published studies of treatment integrity instruments for ABCT. The present study describes the development and initial reliability of the Treatment Integrity Rating System - Couples Version (C-TIRS) for ABCT.
The C-TIRS was used to rate 284 first- and mid-treatment ABCT sessions of 188 couples in four randomized clinical trials.
Average inter-rater reliability for distinguishing ratings between C-TIRS items was fair-to-good for quantity items (intraclass correlation [ICC] = 0.64) and poor-to-fair for quality items (ICC = 0.41). Five C-TIRS subscales were defined a priori to measure treatment components involving cognitive-behavioral therapy, spouse involvement, couple therapy, common therapeutic factors, and overall adherence to the treatment protocol and had adequate internal reliability (α = 0.74-0.89). Inter-rater reliability was fair to good on seven of ten scales but poor on three scales (ICC range = 0.17-0.72).
The C-TIRS was designed to provide information about quantity and quality of the delivery of ABCT components; however, further refinement of the C-TIRS is warranted before it should be used in frontline practice. Clinical implications and recommendations for future research are discussed.
This research output has an Altmetric Attention Score of 4. 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 06 November 2019.
All research outputs
#11,232,259
of 34,363,559 outputs
Outputs from Addictive disorders & their treatment
#43
of 344 outputs
Outputs of similar age
#118,628
of 343,677 outputs
Outputs of similar age from Addictive disorders & their treatment
#1
of 6 outputs
Altmetric has tracked 34,363,559 research outputs across all sources so far. This one has received more attention than most of these and is in the 66th percentile.
So far Altmetric has tracked 344 research outputs from this source. They receive a mean Attention Score of 2.0. This one has done well, scoring higher than 86% of its peers.
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 343,677 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 64% of its contemporaries.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
