With its division into the pathodynamic (clinical) and the psychosocial aspect, functional diagnostics corresponds to the dialectic approach to psychic diseases and thus represents the necessary supplementation to the nosological conception which is based on single-line causal relations. An indispensable element of psychosocial diagnostics are personality-psychological test procedures, the applicability and validity of which in postpsychotic patients is discussed. The disturbances of the personality which are to be revealed in this way are unspecific and can be found in all psychiatric disease groups (e.g. neuroses and psychoses). Their knowledge is an important basis for psycho- and sociotherapy which, as compared to most neurotic developments, shows a higher degree of complications due to the multi-step course in postpsychotic disturbances.
功能诊断分为病理动力学（临床）和心理社会两个方面，它与精神疾病的辩证方法相对应，因此是对基于单线因果关系的疾病分类概念的必要补充。心理社会诊断中不可或缺的一个要素是人格心理测试程序，本文将讨论其在精神病患者中的适用性和有效性。通过这种方式揭示的人格障碍是非特异性的，在所有精神疾病组（如神经症和精神病）中都能发现。了解这些障碍是心理治疗和社会治疗的重要基础，与大多数神经症发展相比，由于精神病后障碍的多阶段病程，心理治疗和社会治疗的并发症程度更高。
