Chronic illness must not only be described on the level of symptoms, but in respect to capacity restrictions and disability. This reflects a bio-psycho-social understanding of illness as outlined also in the ICF
, 2001). For the measurement of capacities special instruments are needed, such as the Mini-ICF
-APP. The Mini-ICF
-APP is an internationally validated and used observer rating instrument for the description of 13 psychological capacity dimensions and degrees of impairment impairment.
Additionally to the observer rating, the self-rating Mini-ICF
-APP-S has been developed. It covers the same 13 psychological capacity dimensions, "soft skills", which are of relevance in mental disorders. This study is the first evaluation of the self-rating.
Data from a clinical sample (N=1143) and a general population survey (N=102) are reported.
Relevant differences in self-reported capacity levels are found between clinical and non-clinical samples, different diagnostic groups, patients who are unfit or fit to work, younger and older persons, males and females. For example, men perceived stronger assertiveness, while women see themselves stronger in relationships. Patients who were presently unfit for work see their overall capacity level lower than patients who were fit for work. From the patient sample, 31% reported a strong impairment in at least one psychological capacity dimension. The strongest capacity impairment was reported by patients with complex disorders (personality disorders, organic disorders), lowest impairment was perceived by patients with eating disorders or specific reactive disorders or phobias.
-APP-S is an economic short rating and can support diagnostics, therapy planning, and serve as additional information within the socio-medical decision making process.
