　抄録　失語症の改善率について，多変量分析を用いて検討を行なった。失語症の改善率はSLTAを用いて，改善可能得点に対する実際の改善得点の割合とした。5要因（初診時のSLTAの言語検査成績，年齢，教育年数，発症から訓練までの期間，CT病巣の大きさ）および6要因（5要因と失語症の改善率）について，クラスタ分析と因子分析の要因分析を行い，重回帰分析を用いて，SLTAの全体および5大項目の改善率の予測を行った。重相関係数の値は，SLTA全体でR＝0.758で，SLTAの「書く」の項でR＝0.810であった。失語症の改善率の予測で，より少ない，より有用な予測の要因としては，初診時のSLTAの言語検査成績，発症から訓練までの期間，教育年数の3要因（重相関係数：0.754）があげられる。

In order to elucidate the factors which have influence on the prognosis of aphasia, correlation between recovery rate of aphasia and the five factors, i. e. initial evaluation of speech test, age, educational level, time between onset and institu-tion of therapy and size of abnormal findings in CT (computed tomography), was studied in 76 right-handed aphasic patients, using multivariated analysis.

Cluster analysis and factor analysis were used for analysis of five factors and multiple regres-sion analysis was used for estimation of recovery rate of aphasia. The method of calculation of recovery rate of aphasia is the same to our previous report.

The results obtained were as follows : As to analysis of factors, first similarity group among initial evaluation of speech test, recoveryrate of aphasia and educational level and second similarity group among time between onset and institution of therapy, size of abnormal findings in CT and age were observed.

As to the estimation of recovery rate of apha-sia, multiple correlation coefficient of regression analysis using five factors were 0.758, 0.444, 0.627, 0.620, 0.810 and 0.375 respectively in total score, hearing, speaking, reading, writing and calculation on standard language test of aphasia.

As to the weight or partial correlation coeffi-cient of regression analysis to the five factors, initial evaluation of speech test, time between onset and institution of therapy and educational level were 129. 46, -49. 93 and 45. 65 respectively and the one of the size of abnormal findings in CT was not high.

Stepwise multiple regression analysis of five factors were made. In stepwise, item of initial evaluation of speech test was selected first, time between onset and institution of therapy second, and educational level thirdly.
