OBJECTIVES: To develop and validate a measure of skin care beliefs and to
describe the skin care behaviors of persons with spinal cord injury (SCI).
DESIGN: A mixed-methods design was used to develop the Skin Care Beliefs Scales
(SCBS). The health belief model framed the hypotheses.
Phase 1 included item
development, content validity testing, and pilot testing.
Phase 2 included
testing the scale structure (principal components analysis), internal consistency
reliability, test-retest reliability, and relationships between the belief scales
and care behaviors. SETTING: Two acute rehabilitation hospitals and Internet
websites. PARTICIPANTS: Patients with SCI (N=462; qualitative/pilot n=56;
psychometric study n=406) participated. INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: The pilot and phase 2 studies, respectively, used 146-item and
114-item versions of the SCBS. A skin care activity log was used to record skin
care behaviors. RESULTS: Content validity indicated that the items were relevant
and clear. The analysis resulted in 11 independent scales reflecting 3 general
beliefs (susceptibility, severity, self-efficacy) and barrier and benefit
behavior-specific scales for skin checks, wheelchair pressure reliefs, and
turning and sitting times. With the exception of skin check barriers (alpha=.65),
Cronbach alphas of the scale ranged from .74 to .94. Test-retest intraclass
correlations were fair to excellent (range, .42-.75). Construct validity was
supported. Hierarchical linear regression indicated that turning benefits,
barriers, susceptibility, and self-efficacy were significant predictors of
turning time. Benefits or barriers were correlated significantly with skin check
and pressure relief adherence (rho range, -.17 to -.33). Self-efficacy was
correlated with wheelchair pressure relief (rho=.18). Skin care behavior
adherence varied widely (eg, 0%-100%). CONCLUSIONS:
The scales showed acceptable
reliability and validity. Further testing with larger samples is desirable.
