PMID 29097963WHAT IT FOUND
The LOTCA showed consistent scores and fit its structure, but it did not track executive function or memory.
Use it as a quick screen, then add another test for those areas.
Key findings
01The test's scores were consistent, and its subscale grouping fit the sample's results.
02The paper reports correlations between LOTCA scales and neuropsychology test scales.
03Men and women had similar LOTCA scores, but men used less time to complete the test.

What it does not show
The analysis used 48 participants, after 2 of 50 recruited did not complete the assessment, so the study is small. Participants were the first people starting treatment at one public centre, so the sample may not represent other addiction services or people not already in treatment. The authors note the sample size is not sufficient to firmly affirm the observed relationships. The orientation scale was near its maximum (7.73 out of 8), so it did not separate mild deficits in this group. The paper reports correlations in Table 3, which is not available in the supplied text, so the exact pattern cannot be checked. The study examined test relationships, not whether using the LOTCA changes treatment planning or patient outcomes.
The easy way to misread this
Do not read this as showing that the LOTCA can replace neuropsychological testing or full occupational assessment in addiction treatment. It screened some cognitive areas, but it showed little relationship with executive-function and memory tests, and the authors say it must be supplemented.
