OBJECTIVE: To investigate the reliability and validity of 2 commonly used
measures of pain related fear in patients with shoulder pain. DESIGN: A preplanned secondary analysis of a prospective single-arm trial involving a
repeated-measures design. SETTING: Outpatient physical therapy clinics.
PARTICIPANTS: Patients (N=80) with a primary report of shoulder pain.
INTERVENTION: All patients completed the outcome measures at baseline and at
follow-up. MAIN OUTCOME MEASURES: Patients completed a modified Fear-Avoidance
Beliefs Questionnaire (FABQ), the 11-item version of Tampa Scale of Kinesiophobia
(TSK-11), and the Shoulder Pain and Disability Index (SPADI) at baseline and at a
48-hour follow-up. Patients were dichotomized as improved or stable at follow-up
based on the Global Rating of Change. RESULTS: Factor analysis indicated 3 stable
factors for the FABQ and 1 stable factor for the TSK-11. Shoulder specific
scoring for the FABQ and TSK-11 were used in subsequent analyses. Test-retest
reliability intraclass correlation coefficient (ICC) was substantial for the FABQ
and the TSK-11. The FABQ correlated significantly with SPADI pain and disability
scores, while the TSK-11 correlated significantly only with SPADI pain scores.
The shoulder-specific FABQ-W (work beliefs subscale) was a better than chance
predictor of missing days of work during the 48-hour study period. CONCLUSIONS:
The modified FABQ and TSK-11 may be appropriate for use in patients with shoulder
pain. Shoulder-specific scoring of these measures resulted in substantial
test-retest reliability, and the FABQ correlated with the SPADI for pain and disability. The FABQ also showed potential for prediction of short-term work loss
in this sample. Pain-related fear may be an important variable in patients with
shoulder pain and merits future consideration in longitudinal studies.
