In general, things are only what they say they are. If an ability is a fear effect, it will say "This is a fear effect".
Unfortunately this isn't always 100% true, so their are... exceptions. For example, the demoralize for the intimidate skill doesn't actually say it's a fear effect, but an FAQ has clarified that, in fact, it is.
But the default rule stands. Things are what they say they are (and do what they say they do) and nothing more.
