Tennessee Functional Status Questionnaire (TFSQ) Internal Consistency: Functional Performance (TFSQ 1) and Capacity (TFSQ 2), Associations with Activity (TFSQ 3), Pain (TFSQ 4), and Acute Care (TFSQ 5) (and Corresponding Duke Activity Status Index [DASI] Metabolic Equivalents [METs] for Pain and Acute Care)
| TFSQ Question | Response | Performance (TFSQ 1) M (SD) | P Value | Capacity (TFSQ 2) M (SD) | P Value | DASI METs M (SD) | P Value |
|---|---|---|---|---|---|---|---|
| Activity (TFSQ 3) | No change or more active | 2.44 (1.44) | 3.24 (1.59) | ||||
| Less active | 1.89 (1.16) | 0.048 | 2.58 (1.54) | 0.047 | |||
| Pain (TFSQ 4) | No | 2.74 (1.34) | 3.73 (1.39) | 8.25 (1.57) | |||
| Yes | 2.01 (1.32) | 0.00 | 2.62 (1.59) | <0.001 | 5.74 (2.10) | <0.001 | |

Abbreviations: METs, Metabolic Equivalents; SD, Standard deviation.
Means and standard deviations for the TFSQ question comparisons were reported and interpreted using numerical values 1–5 to associate with the TFSQ ordinal activity columns A through E. Participants who answered “less active” to Activity (TFSQ 3) reported significantly lower functional Performance (TFSQ 1) and Capacity (TFSQ 2) than those who answered “no change” or “more active”. Similarly, participants who reported “yes” to Pain (TFSQ 4) also reported significantly lower functional performance and capacity and significantly lower mean DASI METs. Patients reporting “Yes” to Acute Care (TFSQ 5) reported lower performance and significantly lower capacity on the TFSQ as well as significantly lower DASI METs.
