The NOT-NOT logic seems as though it shouldn't work but it is as perfect as a weird logic can be. We avoid putting AND US.lo. in the search as not all records include the US location field. APA PsycInfo imports records from PubMed/Medline which uses Medical Subject Headings. This requires a different syntax, .mh. rather than .lo. (Don't worry-- you won't be quizzed on this!)
Also, a best practice is to avoid NOT'ing out other countries as there may be comparative studies that include the US. not-not excludes any study that has the location or MeSH terms we DON'T want (whether it is country/continent based, age based, or human/animal based) but it keeps records that have the terms from the 2nd not phrase. It also keeps records with NO location or MeSH terms.
Nope. Sorry, but extreme caution is being used to develop the limiters. But these will remove a significant number of non-relevant records.
APA PsycInfo uses location codes to indicate the country. HOWEVER, these location codes are single terms only and they cannot be "exploded" which is when a broad term (ex. United States) is selected and, by exploding, all of the indexed terms for states and cities are included. (In Ovid Medline, this same search looks like: not ((exp africa/ or exp asia/ ....). In PsycInfo, each location has to be selected for either inclusion or exclusion, hence the VERY long limit to US studies. Additionally, APA PsycInfo has Medline records in it with MeSH terms. Those needed to be added as well. Fortunately for you, all you have to do is copy the search starting with not and plug it into your search strategy.

This may appear very complicated, but that's because there are records in APA PsycInfo that do not have a language assigned to them.

You can choose the date range using the Publication Year boxes in the Limits area under the text entry box. Or, you can limit by using this phrase:
limit line-# to yr="XXXX - XXXX"
These filters are not perfect in that you will still find animal studies in the human studies filter and human studies in the animal studies filter. This has to do with terminology used to describe the studies. However, these filters are designed to not exclude studies with no terminology to describe the study population (human or animal) or to exclude studies that include terminology for both human and animal.
