weekly or <strong>for</strong>tnightly sessions. The SR bears <strong>in</strong> m<strong>in</strong>d that there may be differences <strong>in</strong> the practice<br />

of the supportive therapy, depend<strong>in</strong>g on the country, with respect to the frequency and duration<br />

of the sessions.<br />

In the NICE <strong>CPG</strong> 8 on Schizophrenia, the supportive therapy or counsell<strong>in</strong>g is compared with<br />

standard treatment. 14 RCTs were <strong>in</strong>cluded (n = 1143) (from 1973 to 2002). The studies <strong>in</strong>cluded<br />

duration and frequency of the sessions (10 – 90 m<strong>in</strong>utes; 1 to 4 times per week). The duration of<br />

the treatment varied between 3 weeks and 3 years. It <strong>in</strong>cluded a schizophrenia diagnosis, from<br />

first episodes to chronic cases. The treatments were normally applied <strong>in</strong> hospitals, outpatients, at<br />

home and <strong>in</strong> the community. The great majority of the studies <strong>in</strong>cluded <strong>in</strong> this section of the <strong>CPG</strong><br />

have selected RCTs where they use or contemplate supportive therapy (control group) and compare<br />

it with other <strong>for</strong>ms of psychological <strong>in</strong>tervention (experimental group). Supportive therapy<br />

and counsell<strong>in</strong>g only appear <strong>in</strong> 4 studies as an experimental group (3 of these studies compare it<br />

with cognitive-behavioural therapy; the other with standard treatment). This means that the studies<br />

were not selected based on the applicability of this <strong>in</strong>tervention, but based on the <strong>in</strong>tervention<br />

of the experimental group.<br />

Supportive therapy <strong>for</strong> people who suffer from SMI and a diagnosis of schizophrenia and<br />

related disorders<br />

Supportive therapy vs. standard care<br />

There are no significant differences <strong>in</strong> the hospitalisation ratios between<br />

people who received supportive therapy or counsell<strong>in</strong>g and those who received<br />

standard care (n = 48; RR = 1.00; 95% CI: between 0.07 and 15.08) 74 .<br />

The NICE Schizophrenia <strong>CPG</strong> <strong>in</strong>dicates that there is not sufficient evidence<br />

to determ<strong>in</strong>e that supportive therapy or counsell<strong>in</strong>g improves the relapse<br />

ratios at the end of the treatment (n = 54; RR = 0.86, 95% CI: between<br />

-10.13 and 1.29) or after a follow-up period when the treatment has ended<br />

(the follow-up period is not <strong>in</strong>dicated) ( n= 54; RR = 1.08; 95% CI: 0.51 and<br />

2.29) 8 .<br />

There is not sufficient evidence to determ<strong>in</strong>e that supportive therapy or<br />

counsell<strong>in</strong>g improves the mental state at the end of the treatment (PANSS: n<br />

= 123; WMD = -2.90; 95% CI: between -10.01 and 4.2) or after a follow-up<br />

period once the treatment has ended (the follow-up period is not <strong>in</strong>dicated)<br />

(PANSS: n = 131; WMD = -4.42; 95% CI: between -10.13 and 1.29) 8 .<br />

It is impossible to determ<strong>in</strong>e whether supportive therapy or counsell<strong>in</strong>g<br />

reduces the cases of death at the end of treatment and after a follow-up<br />

period once the treatment has ended (the follow-up period is not <strong>in</strong>dicated)<br />

(n = 208; RR = 2.89; 95% CI: between 0.12 and 70.09) 8 .<br />

Supportive therapy vs. cognitive-behavioural therapy<br />

There appears to be evidence <strong>in</strong> favour of cognitive-behavioural therapy<br />

when compared with supportive therapy <strong>in</strong> the improvement of general<br />

function<strong>in</strong>g (2 RCT; n = 78; SMI = -0.50; 95% CI: between -1.0 and -0.04) 74 .<br />

There is no difference <strong>in</strong> the number of hospitalisation between the two<br />

<strong>in</strong>tervention groups (2 RCT; n = 88; RR = 1.59; 95% CI: between 0.79 and<br />

3.22) 74 .<br />
