题型:解答题


一般资料:男性,45岁,已婚,外企经理。
主诉:焦虑不安,伴头痛、失眠四个月。
临床表现:求助者在一家外企驻某市办事处任经理,已十余年。老板为美国人,常住美国,有时来本市。经营业务的内容是在本市组织货源,用集装箱海运到美国销售。前几年生意好做,自己的薪金较高,房子车子都有。妻子做中学教师,夫妻感情好,女儿正在上高中,学习优异。近一年来生意有些难做,老板似有不满之意,但是市场变化很复杂,自己虽然很努力,也不尽如人意。逐渐感到生意不会再有起色,为此忧心忡忡。最近四个月以来,开始担心货运船只会不会中途沉没,又担心美国老板会突发某种疾病不治身亡。有时想到虽然现在夫妻恩爱,等到将来退休白发苍苍,妻子仍然貌美年轻,可能会离婚再嫁,又想到女儿考—上大学后要面临工作择业和谈婚论嫁等诸多困难,自己如何能应付得了。伴有头痛、失眠、心慌、胸闷、烦躁,半夜醒来经常是一身大汗,坐立不安,吸烟量明显增加。睡不着觉就只好起来在房间里走来走去,既影响家人的睡眠,楼下的邻居也有意见,但自己也没有什么更好的办法。服用安定有些效果,但又怕长期服用会依赖成瘾。因此寻求心理咨询师帮助。

要对求助者做出诊断,还需要了解( )。

A.躯体检查结果

B.过去诊治经过

C.求助者的个性

D.求助者的婚姻
