对娱乐活动减轻病人症状的直接效果进行了总共81次观察,按五分制将幽默反应(娱乐程度)予以分级,并通过视觉模拟分度来评估症状的减轻程度。根据幽默反应将所有的观察结果分组后,发现幽默反应与症状减轻之间存在着协变关系,而且4级幽默反应(“放声笑”)与5级幽默反应(“开怀大笑”)之间有着明显的差异(Sheffé氏试验,P<0.05)。幽默反应与症状减轻之间的 Pearson 氏相关系数值为0.44。从第7周直 A total of 81 observations were made of the direct effects of recreational activities in alleviating the symptoms of patients, rating the humorous response (degree of entertainment) in quintiles, and assessing the extent of relief by visual analogue division. According to the humorous response, all the observations were grouped and there was a covariation between the humorous response and symptom relief, and there was a co-relationship between the level 4 humorous response (“shout”) and the level 5 humorous response (“laughter”) There was a significant difference (Sheffé’s test, P <0.05). The Pearson’s correlation coefficient between humor response and symptom relief was 0.44. Straight from the 7th week
