Video game genres are more to do with gameplay than theme, so whereas survival horror is a subset of action adventure games with more emphasis on avoiding combat or picking your battles, horror in general is more of a non-game theme (like movies, novels etc.) If it's not survival horror it'll more likely fit into something along the lines of adventure, action adventure or action genres.
EDIT: Just checked Distraint, it's described as an adventure game. It hasn't helped that a lot of sources have taken the concept of 'psychological horror' and then tried to mould it into a video game genre, which it isn't and can't be because it's got nothing to do with gameplay and everything to do with plot and sound/visual feedback.
