This chapter discusses the single-session therapy (SST). The movement away from the 'Ronseal' response where single-session therapy is confined to a single session to the more pluralistic position where it may be one session, but more sessions may take place is summed up by Weir et al. They say about SST: It is not a "one-off" therapy but rather a structured first session which attempts to maximise the client's first therapeutic encounter, understanding that it may be the only appointment the client chooses to attend while entertaining the possibility of work. The pluralistic position also details what can be seen as the paradoxical nature where SST is more likely if clients appreciate that further sessions are possible. Thus, if clients have a sense that they are in control over whether or not they can have further sessions, then they are more likely to be happy with a single session than whether they lack such control.
