Two of the five constructs in the OECD eudaimonia module: a sense that the things one does are worthwhile, and autonomy (being able to do the things one really wants and values). Both on 0–10 scales. The module's items on accomplishment, self-esteem and personal growth are not included in this entry. The worthwhile item is also an OECD core item; ask it only once.
Source
OECD (2025), Box 2.6 (eudaimonia extended module), pp. 39–40, items 1–2. The autonomy item (Martela & Ryan, 2024, doi:10.1027/1015-5759/a000846) was adapted by the OECD to a 0–10 scale.
Usage
Report each item separately: the mean, the distribution and the share scoring 4 or less. The items describe how people see themselves now, not feelings over a period.

The following question asks how worthwhile you feel the things you do in your life are, on a scale from 0 to 10. Zero means you feel the things you do in your life are "not at all worthwhile", and 10 means you feel they are "completely worthwhile".
Overall, to what extent do you feel the things you do in your life are worthwhile?
For the following questions, please use a scale from 0 to 10 to indicate how you feel. Zero means you "disagree completely" and 10 means you "agree completely".
I am able to do things that I really want and value in life.
