For example, I just read an excellent article:
Galderisi S, Mucci A, Dollfus S, et al. EPA guidance on assessment of negative symptoms in schizophrenia. Eur Psychiatry. 2021;64(1):e23. Article EPA Guidance on Assessment of Negative Symptoms in Schizophrenia
There are four assessment instruments discussed in that article that I wish to download or consider purchasing:
Brief Negative Symptom Scale (BNSS)
Clinical Assessment Interview for Negative Symptoms (CAINS)
Schedule for Deficit Syndrome (SDS)
Self-evaluation of Negative Symptoms (SNS)
After nearly an hour searching Google and other databases, I found one of the four scales - thank you Prof. Ann Kring for posting them on your lab's website!
Clinical Assessment Interview for Negative Symptoms (CAINS)
https://esilab.berkeley.edu/wp-content/uploads/2017/12/CAINS.pdf and https://esilab.berkeley.edu/wp-content/uploads/2017/12/CAINS-manual.pdf
But what about the other three scales? Are they simply not available? How do you find out?
And in general, do you have a method for finding tests, scales, measures, etc. that you read about in the literature?
Thanks!
Mark

For the free to use questionnaires, they can often be found in the research paper on validation (or in the supplemental data of this paper). For the paid questionnaires it usually works to find the website of the author's affiliation and send an email through their contact form.
Dear Mark,
BiblioPRO is a virtual library of questionnaires based on Patient-Reported Outcomes (PROMs), promoted in Barcelona by the IMIM Institute.
Find it in https://www.bibliopro.org/index.html
I hope you find it useful,

It is highly dependent on the scales you are looking for (as some are free and some are not). It will be best to look at articles as some are attached at the end of the articles. If not, then I will recommend to contact the author(s) for permission.
