Development of the Development of the proposed itemsproposed items
The HIS/HES* database was used as a reference
1. Overview of questions items used in the population health surveys and of established health status measurement instruments;
2. Selection of questions should be able to measure the concepts underlying each specific domain;

25
Selection of the Selection of the instrumentinstrument
Comparing the instruments, the MH module of SF-36 was selected for following reasons:
WHS and CIDI Short Form are mainly oriented to the measure of negative emotional states
CIDI Short Form seems to be of difficult comprehension for the respondents due to the double time reference period (2 weeks in a raw within the last 12 months)
SF 36 Mental Health is oriented to measure positive and negative emotional states; it is widely used in HIS and it is easy to administer with different data collection techniques in population surveys.
WHO-Eurostat-UNECE Meeting "Measurement of Health Status", Budapest, November 2005
26
Positive emotional state Calm and peaceful Feel happy
Negative emotional state Feel down in dumps Feel down hearted Feel nervous
A lot of specific aspects from both emotional states are excluded. To analyze depression, for example, several other items are considered in measurement scales used in psychiatry but including them the parsimonious criteria couldn’t be respected.

The initial proposal was the European Health Status Module that
includes the Mental Health scale of SF-36 (except the quest of feeling
nervous). After a discussion within the TF, aiming to introduce a measure of intensity, just two questions out of five
were selected.

The initial proposal was the adapted European Health Status Module
integrated with a question of WHS on the use of visual aids.
After a discussion within the TF, the answering categories were changed
in order to measure the severity of sight problem.
