Draw the Triad.

Disability = any restriction or lack of ability to perform an activity (resulting from an impairment). Relative to prior status.

Question 25

what are casual attributions in asthma?

- knowing the cause of an illness or other traumatic incident can help make the experience less anxiety provoking and the future more predictable - this process of finding a cause for an asthma attack helps patients to make sense of their illness experiences to guid their future actions to cope with the condition.

Question 26

What is the new model for QOL ? Draw this and describe its main features.

Answer 26

International Classification of Function – Interaction of Concepts Refer to slide 28 in lecture on “Asthma Control” for diagram. -This model takes into consideration the context of the person’s life as well as the individual him/herself. This allows us to say that even with an impairment a person can have a good QOL. Disability and functioning are viewed as outcomes of interaction between health conditions (diseases, disorders and injuries) and contextual factors. Among contextual factors are external environmental factors (for example, social attitudes, architectural characteristics, climate, terrain…), and internal personal factors (e.g. gender, age, coping styles, social background, education, and other factors that influence how disability is experienced by the individual).

Question 27

Give examples for each of the components of “International Classification of Function – Interaction of Concepts” in an old patient with asthma.

♦ Health condition: asthma ♦ Body function and structure: breathlessness, tight chest, asthma attacks, wheezing ♦ Activities (limitations): Independent in self-care, looks after young family, works (but part time) ♦ Participation (restrictions): Participation in family in role of mother and wife. On days of poor health unable to do this as much as wants + Needs to pace how much she does each day and therefore can only participate in a reduced amount of activity ♦ Personal factors: Supportive husband + difficult relationship with mother + loss of confidence ♦ Environmental factors: newly built house (no damp)
