No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.

Praxis harmonization actions
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Confirm that the construct and coding are unchanged before pooling or recoding.

Questionnaire
The next questions are about drinking alcoholic beverages. Included are liquor (such as whiskey or gin), beer, wine, wine coolers, and any other type of alcoholic beverage. In any one year, {have you/has SP} had at least 12 drinks of any type of alcoholic beverage? By a drink, I mean a 12 oz. beer, a 4 oz. glass of wine, or an ounce of liquor.

No normalized longitudinal change evidence is available for this variable. Absence of events must not be interpreted as proof of cross-cycle equivalence.

Praxis harmonization actions
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Review the adjacent codebooks/methods. Keep this boundary as documentation variation unless source evidence confirms a substantive method or instrument change.
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
