Psych*	Include mentions of words that are direct derivatives of “psych” (e.g., “psychosocial,” “psychiatric,” “psychological”). Exclude mentions of words that signify separate concepts.
Lunatic, lunacy, insane, insanity	These terms once held pseudo-scientific meanings but have been considered completely inappropriate and outside all formal classification systems for decades. Nonetheless, we considered it important to include these terms, as some reports may include them (for example, a number of countries still have “Lunacy Acts” in their legislation, even if outdated).
Unsound	This is intended to capture discussion of people with psychosocial disabilities as having “unsound” minds or “unsound” reasoning. Exclude mentions of the term “unsound” that clearly do not relate explicitly to people with psychosocial disabilities (e.g., exclude mentions of “unsound practices” if these do not refer explicitly to people with psychosocial disabilities).
Mind	Exclude mentions of the term “mind” that clearly do not relate explicitly to people with psychosocial disabilities.
Asylum	Exclude mentions of the term “asylum” that clearly do not relate explicitly to people with psychosocial disabilities (e.g., exclude mentions of asylum seekers, or asylums for children with physical disabilities).
