Why are there fewer outcomes for the 2014-2015 state estimates than for previous publications of state estimates?

  • The NSDUH underwent a partial redesign in 2015, so some measures in 2015 are not comparable to their counterparts in 2014. Since NSDUH state estimates pool 2 years of data, estimates for measures that weren’t comparable between the 2 years could not be produced for this publication of state estimates.

    SAMHSA will produce a full set of state outcomes when 2 years of comparable data are available, which will be the 2015-2016 state estimates that will be released in December 2017.
