Significant improvement was seen in the four BPRS factors: thinking disturbance, hostile-suspiciousness, withdrawal\u2013retardation and anxious depression. The first two of these factors were improved by day 5. Significant improvement was seen up to day 22 for three of the four factors, but without significant improvement during the last week (although scores continued to drop). The half of the sample showing greater overall improvement did not improve faster than the sample as a whole. These more improved subjects did not differ significantly from the less improved subjects in the thinking disturbance factor until day 15, suggesting that at least a two-week neuroleptic trial would be necessary to begin to differentiate more and less responsive patients. The longer-term course of improvement cannot be determined from these data. The withdrawal\u2013retardation and anxious depression factors showed their greatest improvement later than the \u2018positive\u2019 symptom factors, suggesting that the former may improve as a result of change in the latter.<\/jats:p>","DOI":"10.1192\/bjp.160.3.365","type":"journal-article","created":{"date-parts":[[2008,10,15]],"date-time":"2008-10-15T04:56:07Z","timestamp":1224046567000},"page":"365-371","source":"Crossref","is-referenced-by-count":13,"title":["Timing
