Their impairments were largely characterized
by functional deficits in self-care skills and social
functioning. Most patients had had previous psychotic
episodes requiring hospitalization; five patients were in
their first episode. Six patients were being treated with
clozapine, but the remaining patients were being treated
with conventional antipsychotic medication. At the time
of data collection, the newer atypicals were not available
at the hospital. Closed envelopes with lots were used to
randomly assign the patients to experimental or control
groups of 21 patients each.
針對兩組訓練前後進行T檢定
組間及訓練前後進行T檢定
注意力未有明顯類推效果:CPT、SPAN無明顯效果,Trail making A在控制組有改善,Trail making B在訓練組有效果,Stroop則兩組皆有效果
在記憶方面:RAVLT Rey Complex Figure Retention兩組皆有改善,但差異效果很小
執行功能:有generalization effects
Mazes test time score,(迷津測驗反應時間)、word fluency(字詞流暢度)、連環圖系(Picture arrangement)都在訓練組有效
