In this study, it was aimed to assess the relation between cognitive measures and frequency of METH use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Ninety-eight participants with methamphetamine use disorder were assessed with Wisconsin Card Sorting Test (WCST), Victoria-Stroop Word Color Test (SWCT), Trail Making Test (TMT) A and B. Participants were followed up during 6-month period with multiple urine toxicology tests (at baseline, month 1, month 2, month 3 and month 6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Participants who had their prescriptions regularly were more likely to have higher rates of METH-negative urine results ( P\u2009=\u2009.003). Participants who had more correct numbers, completed more categories and had more conceptual level responses on WCST were more likely to use lower frequency of METH (OR\u2009=\u20090.006, P\u2009&lt;\u2009.01; OR\u2009=\u20090.171, P\u2009&lt;\u2009.001; OR\u2009=\u20090.024, P\u2009&lt;\u2009.001; respectively). The higher error numbers and perseverative error rates on WCST were associated with more frequent METH use (OR\u2009=\u20090.023, P\u2009&lt;\u2009.001; OR\u2009=\u20090.076, P\u2009&lt;\u2009.001). Interference factor on SWCT was related with lower frequency of METH use whereas color naming factor on SWCT was related with higher rates of urine results (OR\u2009=\u20090.012, P\u2009&lt;\u2009.001; OR\u2009=\u20093.628, P\u2009&lt;\u2009.001; respectively). Higher TMT B-A score was related with more frequent METH use, although the significance disappeared after adjustment (OR\u2009=\u20090.002, P\u2009&lt;\u2009.001). Having psychotic symptoms predicted less frequent use, but after adjustment for other significant variables, there was no significance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Lower frequency of METH use in the follow-up could be predicted by neurocognitive assessments.
