"highly constructed"

Hi,

When a questionnaire is highly constructed, precoding of the categories typically occurs before the data are collected.

Does “highly constructed” mean “constructed in details” or anything else?

Thanks a lot

Yes. You can mean it so. Highly, deeply, closely, etc…are called abstract adverbs as high and deep alone are adverbs. She’s highly appreciated means she’s appreciated very much. Back to your example, highly constructed means it’s constructed very carefully, detailed…
