Monophobia is often seen as part of the agoraphobic cluster. According to research, there are no particular personality differences between agoraphobics and members of the general population. 'Fear of fear' (fear of a panic attack) seems to be a component of the agoraphobia (and a major part of monophobia), but there are many other factors that lead to the avoidance central to the disorder and not all agoraphobics experience panic attacks. People with agoraphobia typically suffer from a 'cluster' of phobias as mentioned and Monophobia may be one. Generally agoraphobics will find it very difficult or impossible to carry out certain activities. These could be going into crowded or public places, lifts, public transport or simply anywhere away from home where 'escape' or immediate access to help is not possible. They will probably also fear standing in queues, going on bridges or sitting in any place where they feel 'trapped', such as at a hairdresser's or dentists. A companion for outings is often sought and rapidly becomes essential. There can also be additional fears, predominantly 'social' ones such as a fear of blushing, trembling, talking eating or writing in front of people and of being stared at. (These latter fears can also be part of social phobia or separate specific phobias and don't necessarily mean that someone suffering in this way is agoraphobic or monophobic.) There may also be obsessional and depressive symptoms. If the person becoming agoraphobic was significantly depressed before onset, which is more common when the problem appears later in life, this could be the disorder that is treated first.
