Methodology Notes:

In 2014 and 2015 changes were made to the National Survey on Drug Use and Health (NSDUH) resulting in the need to revise the baselines and targets for 20 HP2020 objectives. In 2014, the changes to NSDUH primarily focused on revising the sample design, such as modifying the distribution of the sample across the 50 states and the District of Columbia and reducing the oversampling of youths and young adults. In 2015, SAMHSA implemented changes to the NSDUH data collection equipment, respondent materials, and survey questionnaire, including revisions to existing measures (e.g., prescription drugs, methamphetamine, hallucinogens, inhalants, and binge alcohol) and the addition of new questions (e.g., sexual orientation and attraction, disability status, and identification of active duty family members).

The 2014 changes to the sample design are expected to result in more precise national estimates overall as well as more precise estimates for older adults. The 2015 changes are expected to improve the quality of data, and the questionnaire revisions will address SAMHSA's substance use and mental health policy and research needs.

The following report outlines all of the changes that were made to the NSDUH in 2014 and 2015.

Caveats and Limitations:

While the question used to obtain baseline data takes into account all kinds of harm, some respondents may focus on physical harm only. Consequently the measure is a very conservative estimate of the perceived harm.

Trend Issues:

Estimates prior to data year 2015 were removed due to a questionnaire redesign of the National Survey on Drug Use and Health (NSDUH) beginning in data year 2015, which resulted in a break in trend. Estimates were removed for both national level, and state-level data including the category ‘all reporting states’.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch:

During regular data collection and processing checks, errors were identified in the NSDUH data. These errors affected the data for Pennsylvania (2006-2010) and Maryland (2008-2009). These errors had minimal impact on the national estimates and no effect on direct estimates for the other 48 states and the District of Columbia. Comparing estimates for Pennsylvania, Maryland, the mid-Atlantic division, and the Northeast region were of most concern. As a result in 2013, the original baseline was revised from 49.7 to 49.4 percent. The target was adjusted from 54.7 to 54.3 percent to reflect the revised baseline using the original target-setting method. In 2015, SAMHSA implemented changes to the NSDUH data collection equipment, respondent materials, and survey questionnaire, including revisions to existing measures (e.g., prescription drugs, methamphetamine, hallucinogens, inhalants, and binge alcohol) and the addition of new questions (e.g., sexual orientation and attraction, disability status, and identification of active duty family members). The 2015 changes are expected to improve the quality of data, and the questionnaire revisions will address SAMHSA's substance use and mental health policy and research needs. As a result in 2019, the baseline was again revised from 49.4 to 56.7 percent. The target was also adjusted from 54.3 to 62.4 percent to reflect the revised baseline using the original target-setting method.
