SIDA is not like a military/IC or law enforcement background check... there's no subjectivity involved.
It's black and white, pass/fail.... either you were convicted of the specified crimes in the specified time frame or you were not.
Answer the questions literally, do not provide any more info than they ask for. For SIDA it won't matter.
For filling out job applications and interviews, it can be a little grey. Generally don't tell them anything they didn't ask for, but if it's a grey area it may be safer to disclose something than not.
But in some cases they would *like* to know more but employment law prevents them from asking. If you tell them anyway, they can use it to make their decision. Be careful of open-ended interview questions such as "is there anything else about your background you want to tell us"? Interview is not confessional. Don't provide any adverse info which they didn't ask for... you may have to use your judgement in a grey area.
