- We will request permission to administer the Child Health Questionnaires (PF 50 and CF87) to all patients who are enrolled in this protocol. This instrument has been validated for use in children ages five and older. Children 10 years and older will complete the child version. The Child Health Questionnaire (CHQ) has been normed in a representative sample in the US, and is being used in large population studies in Australia, Ireland, and the UK. Additionally, it has been rigorously translated into a number of languages using international guidelines including American-Spanish, Canadian-French, Dutch, Finnish, French, German, Italian, Greek, Honduran-Spanish, Mexican-Spanish, Norwegian, Portuguese, and Swedish. For this study will purchase the CHQ in American- Spanish in order to include Spanish-speaking subjects in this part of the study. The costs to purchase the CHQ in numerous languages would be prohibitive for this pilot study. However, if a significant number of subjects in a specific language are recruited, we will consider the purchase of the CHQ for that group of subjects.
