There is a need to develop and refine instruments, which are able to capture diverse belief systems commonly employed by people with mental illness and also elicit local explanatory models of illness, their attribution and help seeking.
For a Europa lander to be launched in the 2020 2030 timeframe, we propose to use a simplified instrumented melting probe which is able to access and sample depths of a few meters without the necessity of heavy and complicated drilling equipment.
For these reasons we decided to use only one QoL questionnaire - the dermatological specific instrument Skindex-29 - which is able to better describe and score the real impact of skin toxicities on daily QoL, compared to generic tools as EORTC QLQ C-30 or SF-36.
We used the Italian version of a well-known dermatological instrument, the Skindex-29 questionnaire [ 6- 8], which is able to better describe and score the real impact of skin toxicities on daily QoL.
It is the instrument which is most able to assess the constructs of SDM and PCC without actually using the instruments developed specifically by key authors in those domains [ 12, 13].
When he reaches the percussion instruments, special prominence is given to timpani and xylophone, which are able to play particular pitches, but he does not neglect the more rhythmic members of that family.
Other requirements that are extremely important to consider when selecting an outcome measure are the appropriateness (degree to which the instrument responds to the questions that the specific evaluation intends to study) and accuracy (the degree to which the measuring instrument is able to capture real differences) [ 2, 5].
The construct validity was also assessed using the known-group method, a kind of validity which determines whether the instrument is able to detect differences between groups [ 19, 27].
