PMID 37332296WHAT IT FOUND
Adding monthly motivational interviews to cognitive remediation did not significantly improve programme completion rates, though more patients finished.
Among those who completed, the interview group showed greater gains in global functioning and hope than the group without interviews.
Key findings
01The difference in completion rates between the standard programme and the programme with motivational interviews was not statistically significant.
02Among participants who completed the programme, those who received motivational interviews had significantly greater improvements in global functioning and personal recovery scores than those who did not.

What it does not show
The study was retrospective and relied on medical records, with a very small sample size (26 total, 15 completers). Only patients who completed the programme were included in the outcome analysis, which excludes data from dropouts and may bias results toward those who responded well. The groups were formed by time period rather than randomisation, so differences could be due to therapist experience or other changes over time. The flexible duration in the interview group confounds the effect of motivational interviewing with the effect of shorter treatment periods.
Declared interests
The authors declared no potential conflicts of interest and received no financial support for the research.
The easy way to misread this
Do not conclude that motivational interviewing significantly improves programme completion rates. The observed increase from 42% to 75% completion was not statistically significant. The benefits were seen only in the subset of patients who finished the programme, so this does not prove the intervention prevents dropout.
