Name of Questionaire

Functional Status II-R (FS II-R)


Generic measure of functional status in children including children with chronic physical conditions. Describes child's functional status in the previous two weeks. The revised Functional Status II has both long and short versions. The long version contains 43 items with General Health and Stage Specific factors for each age group (age ranges 0-9 months, 10 months, - 2 years, 2-5 years, 5-11 years). The short version FS II-R uses a common core of items across the entire age span.

Domains & Categories (#)

All age groups include total functional status and general health status factor. Stage-specific factors included in long form by age group are as follows:
0-2 Years: Responsiveness
2-3 Years: Activity
4 Years and Older: Interpersonal Functioning

Scaling of Items

3-point Likert scale, double element. The parent first rates the extent of difficulty with specific behaviors and then rates for those behaviors with difficulty, the extent to which the difficulty is due to illness.


Percent of possible points that the child obtains of the total for the scale and age group (Stein et al., 1990). Scoring is based on the subset of items chosen by the parent indicating that the child's functional status was partially or fully impacted as a result of illness (FS II-R). Normative information is not available.


  • Internal consistency alpha > .80 (Stein et al., 1990)
  • Modified FS II-R short form alpha = .78
  • Test-retest: not reported


Yes (Stein et al., 1982; Stein et al., 1990) Scales differentiate between children with and without chronic illness. Concurrent validity is demonstrated by significant correlation with standard morbidity indicators, especially short-term indicators.
