Mrs Boevink is a leading light in the Netherlands. She has been pivotal in a movement that empowers people to pick up their lives and make the most of it. She is a published author, published often and published with many others. A person as notable deserves an article in Wikipedia but for now, Wikidata will do.
When people talk about quality, it is easily abstract. Mrs Boevink was instrumental in the development of the HEE method. It has been proven as an effective intervention of aiding people in their process of recovery. This "intervention" has no link yet in Wikidata and, I have no clue how to indicate that it has been certified as such.
By including information like this, it is easy to learn about recovery, about HEE, about Mrs Boevink and, it enables people to inform themselves. Insurance companies make it really hard to fund the people best positioned to provide HEE. They manipulate information by informing the public just so. Such manipulations become hard when Wikipedia provides its NPOV about this topic.
Both Wikipedia and Wikidata are works in progress. They do improve their quality and it does not take a genius to understand how Wikipedias in a language are manipulated. It takes some sober reflection to understand that an existing lack of information enables manipulation as easily. Subjects that are associated with discrimination, stigmatisation are exactly where people are vulnerable and where basic, encyclopaedic information is really needed.
