Abstract
OBJECTIVE
To develop and psychometrically test the Self-Efficacy and Performance in Self-Management Support instrument for physiotherapists (SEPSS-PT), based on the SEPSS-36, the corresponding instrument for nurses.
DESIGN
Instrument development including content validation and psychometric evaluation (construct validity, factor structure, and reliability).
SETTING
Data were collected from literature, expertmeetings, and online questionnaire PARTICIPANTS: Next to a comprehensive literature study, experts (self-management experts (n=2); physiotherapists (n=10); patients (n=6)) and physiotherapists and physiotherapy students (n=334), participated in different stages of the study.
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
Not applicable. A literature study (n=42 reviews) and consultations with physiotherapists and patients identified the specific content for physiotherapy. The Five-A's model and overarching competencies of "supportive partnership attitude", were used to structure the items. Psychometric evaluation of the draft questionnaire (40 items) was tested in a sample of 334 physiotherapists and physiotherapy students from the Netherlands, of whom 33 filled out the questionnaire twice to establish the test-retest reliability.
RESULTS
Confirmatory factor analyses revealed satisfactory fit indices for both the 6-factor model and hierarchical model, with best fit for the 6-factor model. The questionnaire discriminated between physiotherapists and physiotherapy students, and between physiotherapists who did or did not consider self-management support important. The overall internal consistency (Cronbach's alpha) was high, both for the self-efficacy and the performance items. In most of the subscales, test-retest intra-class correlation coefficients for both overall self-efficacy and performance were good, but in 3 subscales insufficient for performance.
CONCLUSION
The SEPSS-PT questionnaire is a 40-item, Likert-scaled instrument with good content and construct validity, good internal consistency and reliability, and sufficient test-retest reliability. Future research in a larger and more diverse sample could confirm stability and discriminating power.
