CHIS Questionnaires (Translated)


In addition to English, CHIS is conducted in:


Separate interviews are conducted for adults (age 18 and older), adolescents (age 12 through 17) and children (birth through 11 years of age). For children, we interview the parent or guardian in the household who is most knowledgeable about the child's health. Adolescents are interviewed directly about their health and behaviors, although their insurance information is collected from the adult. 


About Translation and Cultural Adaptation:

  • To produce English equivalent translations, the CHIS translation process involves four review stages: (1) initial translation, (2) review by ATA/CA Court Certified translators/interpreters, (3) translation moderator review, and (4) translation reconciliation.
  • CHIS questionnaires also undergo a cultural adaptation process. The cultural adaptation process involves the following stages: (1) English simplification, (2) cultural review by bilingual/bicultural community-based health representatives, (3) final cultural review and integration of recommendations, and (4) CATI pilot and final adjustments.
