OBJECTIVE: To develop a self-efficacy scale for people living with multiple
sclerosis (MS) and spinal cord injury (SCI) that can be used across diagnostic
conditions. DESIGN: The scale was developed using modern psychometric methods
including item response theory. Items were administered at 3 time-points of a
longitudinal survey of individuals with MS and SCI. SETTING: Survey participants
with MS were recruited from the National MS Society, and participants with SCI
were recruited from the Northwest Regional Spinal Cord Injury Model System and
the Shepherd Center at the Virginia Crawford Research Institute in Atlanta, GA.
PARTICIPANTS: Adults aged 18 years and older reporting a definitive diagnosis of
MS (N=473) or SCI (N=253). INTERVENTIONS: None.
MAIN OUTCOME MEASURES: Evaluation
of the new self-efficacy measure called the University of Washington
Self-Efficacy Scale (UW-SES) included comparisons with the Chronic Disease
Self-Efficacy Scale and other patient-reported outcome measures. RESULTS: UW-SES
has excellent psychometric properties including well-functioning response
categories, no floor effects, and low ceiling effects. A long form (17 items) and
a short form (6 items) are available. The correlation between the score on the
newly developed scale and the Chronic Disease Self-Efficacy Scale was high (.83),
providing support for convergent validity. Higher self-efficacy scores were
statistically significantly associated with better mental health, better physical
health, less fatigue, less stress, less pain interference, less pain, fewer sleep
problems, and lower depressive symptoms. CONCLUSIONS:
The UW-SES is a
psychometrically sound instrument for measuring self-efficacy, validated in MS
and SCI, and can be used across both conditions. Both the long form and the short
form are available free of charge.
