You are going to run into some issues.
1. Most (legitimate) screening tools will not be found online, because they are protected materials. If these are in any way connected with a medical record, you should only use empirically supported assessments, as anything else would open yourself (and your facility) to liability.
2. You may not have the proper training/supervision to give the assessments, as they are in the domain of clinical psychologists. Simple self-report measures are probably what you are looking for: BDI, BAI, etc. They should never be used without other assessments and a clinical interview, but they will be a flag at least for your psychologist to follow up on. Personality disorders and the like are much trickier to evaluate, and I'd tread much lighter if you are put in a position to "screen" for them, because they require more involved measures which are far outside of your scope, and you shouldn't be giving/interpreting them.
