For (1), you are correct. [AWBWT](https://www.atusdata.org/atus-action/variables/AWBWT#description_section) should be multiplied by the time spent on all activities eligible for the Well-Being module. For (2), if you are using one observation per Well-Being module respondent, along with their average affect during a certain activity, then you should use the [WBWT](https://www.atusdata.org/atus-action/variables/WBWT#description_section) weight for your multivariate analysis.

To summarize, use the AWBWT method described in the [previous answer](https://forum.ipums.org/t/when-to-use-weights-with-the-atus-well-being-activity-level-data/1223/1), modified as mentioned in (1), to generate your average affect. Then, use the WBWT weight for your multivariate analysis of this average affect.

Hope this helps.
