Correction to: Neuropsychopharmacology, published online 06 June 2022

The sentence beginning ‘Low average positive affect...’ should have read ‘Low average positive affect was also associated with higher proportion of days of use’.

The sentence beginning ‘Craving log(iSD2) and average PA...’ should have read ‘Craving log(iSD2) and lower average PA remained associated with proportion of opioid-use days, whereas average craving did not’.

These errors were solely in the narrative description of results, not in the data. The original article has been corrected.
