Three more centers (Barcelona, ​​Delhi, and Tokyo) were added at this stage of WHOQOL development.

They translated the core question, conducted focus groups to ensure the wording of the question was regionally appropriate, and in the case of Delhi and Tokyo, added it to the pilot tool for testing purposes across the country.

I suggested a question.

The WHOQOL Coordination Group then pooled all questions from all centers to form a 'global question pool' of approximately 1800 questions.

Content analysis of the questions identified many semantically equivalent questions (e.g.

, “How often are you tired?

” and “How often are you tired?

”), thus making the global question The number of questions in the pool has been reduced.

The semantic equivalence assessment was done by consensus of a small working group and then reviewed by all principal investigators.

The questions were then carefully considered to determine the extent to which they met the WHOQOL question criteria (see Appendix 2).

As a result, the number of questions in the global pool has been significantly reduced to approximately 1000 questions.

The principal investigator at each field center then ranked the questions for each aspect based on "how much it tells you about the quality of life of respondents in your culture" as determined from focus group discussions .

The Center calculated 4,444 and 236 questions were selected for his WHOQOL pilot instrument.

As a final step, it was decided to use his 5-point Likert scale for all items in the instrument.

To ensure comparability between WHOQOL field centers, a visual analog scaling method was used to specify anchor points for the different types of response scales used in the instruments (i.e.

, “Very Satisfied” and A marked English anchor point scale was used).

was).

- Very people dissatisfied," "Not at all - Very," "Not at all - Completely," and "Not at all - Always.

" The scale with anchor points “Very Poor – Very Good” and “Very Dissatisfied – Very Satisfied” is also included in some centers (), with 25%, 50%, and 75 between Received the best descriptor of % points.

Two anchors for each response scale (see pages 31-32 for details).

Contains four response scales to assess intensity, capacity, frequency, and rating (see Chapter 4 and Appendix 1 for details.
