21.01 - Assessment of Psychiatric Disability
In assessing psychiatric disability the following are among the factors requiring consideration:
- that many psychiatric diagnoses are simply brief description of objective medical findings and of subjective symptoms elicited at the time of a single examination.
- The nature of a psychiatric disorder is such that its severity can be measured only indirectly and by reference to subjective criteria, including effects on lifestyle. Greater weight is given to the pattern of illness over a period of time than to findings at a single examination, as these may reflect only a time of either brief exacerbation or remission.
- The assessment tables have criteria with multiple elements to define the degree of severity of the psychiatric condition. Most of the elements need to be satisfied in order to award the particular assessment level. It is not necessary for every element at a given level to be satisfied in order to assess at that level, although the majority of the elements should be present. A single element from a given level is not sufficient to award assessment at that level .
- When applying the tables only the effects of the psychiatric conditions are to be taken into account. For example inability to work, reduced participation in recreational activities and increased family conflict may all be present but not necessarily consequences of the psychiatric conditions.
- that changes in psychiatric terminology in recent years requires interpretation.
- that, especially in later life, new psychiatric conditions may arise which may be modifications of the pensioned psychiatric condition or may be entirely unrelated in origin. The interaction may worsen, ease or even obliterate the pensioned condition. Assessment should then be based on the worsened state of the pensioned condition or on the pensioned condition prior to obliteration or alleviation, whichever is more favourable to the pensioner.
