that treatments that target these traits, e.g., CRT or CREST, could be most effective [116], particularly if modified to suit these individuals' needs [129]. Perhaps, then, the answer to this could be identifying patient subgroups that might respond particularly well (or not) to one treatment over another and tailoring treatment

is conducted in outpatient settings, omitting those most critically ill (who are most likely to be using inpatient services) from being participants and limiting the ability of researchers to evaluate the impact that different treatment settings have on the efficacy of psychological treatments, how successfully treatments translate to different levels of care and make recommendations regarding the best setting for treatment [50]. More intense treatment contexts such as inpatient or day-patient typically mean that patients live-in or spend up to around 10 h at the treatment location, which is significantly more therapeutic input than the typical 1 h per week of treatment offered to less chronically ill patients who access outpatient treatment [130]. Despite this, research indicates that evidence comparing inpatient and outpatient treatment shows there to be little or no differences regarding outcome between the two treatment settings and the majority of young people suffering with anorexia can be kept safe and managed well as outpatients, with high levels of patient satisfaction and significantly lower costs [131, 132]. Though the severity of some cases might mean that inpatient treatment is necessary to reduce immediate risk, research shows that a short inpatient stay followed by day-patient treatment was no less successful or safe than inpatient treatment [133], and extended hospital admissions might actually have adverse impacts on long-term recovery [134]. Considering such research, further investigation about effective settings for psychological treatment would be beneficial so that better informed decisions can be made regarding efficacy, safety, suitability for various age groups or stages of illness

and cost effectiveness of treatment for anorexia in various settings.
