Abstract
BACKGROUND: The Osteopaths' Therapeutic Approaches Questionnaire (Osteo-TAQ) has demonstrated content, construct, and face validity across multiple jurisdictions but required cognitive validation for use in the United Kingdom (UK). OBJECTIVES: To assess the cognitive content and face validity of the Australian-adapted Osteo-TAQ (Osteo-TAQ(Aus)) with practising UK osteopaths, and to determine whether any revisions were necessary. METHODS: Cognitive interviews were conducted with six (n = 6) UK osteopaths using a combination of think-aloud and verbal probing techniques, informed by the Cognitive Interview Reporting Framework (CIRF). Interviews were recorded, transcribed, and analysed using team-based content analysis to identify issues of item interpretation, clarity and relevance to UK practice. RESULTS: Strong alignment with UK practice was demonstrated across all 36 items. No items required modification, providing positive validation evidence for cross-jurisdictional stability. Participants reported that the Osteo-TAQ(Aus) items were relevant, understandable and reflective of their day-to-day clinical practice. CONCLUSION: This study provides the first evidence of cross-jurisdictional cognitive stability for the Osteo-TAQ(Aus), demonstrating robust content validity in its country of origin and suitability for use in a UK setting. These findings support its continued use in UK-based research and professional development initiatives aimed at exploring therapeutic approaches and conceptions of practice.
