Low back pain affects a substantial number of adults each year and is
persistent or recurrent for many. Self-efficacy is an important predictor of
functional recovery. The purpose of this investigation was to assess
the preliminary reliability and validity of the Low Back Activity Confidence
Scale (LoBACS) for individuals with histories of low back pain or lumbar surgery.
DESIGN: Two overlapping samples of patients who had undergone a microdiskectomy
participated: a test-retest sample of 21 individuals and a validity sample of 53
individuals. METHODS: Low Back Activity Confidence Scale items pertaining to
self-efficacy for functional activities (FnSE subscale), self-regulation of back
health (Self-RegSE subscale), and regular exercise (ExSE subscale) were generated
from existing literature and clinical observations. The test-retest sample
completed the LoBACS twice, approximately 10 days apart. The validity sample
completed the LoBACS and measures of functional performance, self-reported
leisure and occupational physical activity, pain, fear beliefs, disability, and
quality of life. RESULTS: The FnSE, Self-RegSE, and ExSE subscale scores and
LoBACS total score had excellent to acceptable test-retest reliability
(intraclass correlation coefficients of .924, .634, .710, and .850, respectively)
and internal consistency (Cronbach alpha coefficients of .924, .804, .941, and
.911, respectively). The LoBACS subscales were correlated in expected directions
with physical performance, physical activity, pain, fear beliefs, disability, and
quality of life, providing initial evidence of concurrent validity. CONCLUSIONS:
The findings provide preliminary content and concurrent validity and interrater
and internal consistency reliability for the LoBACS measure of self-efficacy for
individuals with histories of low back pain and lumbar microdiskectomy.
