1.  CHQ stands for Child Health Questionnaire.  The two letters that follow indicate whether it's to be completed by the parent/guardian (PF) or the child (CF).  The number indicates length--the actual number of items to be completed.

2.  The CHQ is a paper and pencil questionnaire comprised of sets of questions (known as item sets or scales) that have been specifically developed for children and adolescents five years of age and older.  The CHQ assesses a child’s physical, emotional, and social well-being from the perspective of their parent/guardian or, in some instances, the child directly.

3.  The child/adolescent’s general health, change in health, physical functioning, bodily pain/discomfort, limitations in school work and activities with friends due to physical problems or emotional/behavioral difficulties, behavior, mental health, and self-esteem.

4.  There are two parent lengths—50 and 28 items.  The 28-item form is best for large population studies where many children will be evaluated.  The most common parent-completed form is the CHQ-PF50.  The child-completed form is the CHQ-CF87, consisting of 87 items.  A child short-form is not yet available.

5.  The child’s parent or guardian completes the CHQ-PF50 and 28.  The CHQ-CF87 can be completed by children 10 years of age and older.

6.  The CHQ is designed to be completed by the parent/guardian or child without assistance.  Interviewer scripts have been developed and used, but the norms were collected by using a mail-out/mail-back method of administration.

7.  There are two ways to score and report CHQ data.  First, overall means for the individual CHQ scales and items can be derived using a simple summated rating approach.  This method yields a profile for each of the 14 health concepts.  Second, the individual scale scores can be aggregated to derive two summary component scores of physical and psychosocial health.  A higher score always indicates more favorable ratings of health and well-being.  Scores can be compared to a representative sample of children in the US. Preliminary profiles for some child conditions have also been collected.  All users are asked to purchase a copy of the User Manual as it contains important information about the CHQ including the forms themselves, administration, scoring and interpretation. Norms and sample size estimates are also provided.

8.  Discussions are currently under way to develop state-of-the-art administration, processing and scoring systems.
