Registered Massage Therapists’ Intention to Use Standardized Outcome Measures Hemsworth, Robert B.
Background: With the emergence of evidence-based practice (EBP) in healthcare, the use of standardized outcome measures (SOMs) has become important for providing credible and reliable treatment justification (Jette, 2009; Fawcett, 2007). However there are concerns that clinical decision-making by registered massage therapists (RMTs) may be based on education, prior experience, and peer opinion, rather than research and scientific evidence (Schroff, 2012; Fawcett, 2007). The theory of planned behavior (TPB) offered a theoretical basis to explain SOM behavior by RMTs and provide behavior change recommendations (Ajzen, 1988; 1991; 2005; 2006). Purpose: This study was framed by the TPB to measure and explain SOM behavior by RMTs. The primary research question was: What are RMTs’ intention to use SOMs? Sub questions were: Which theory-based factors most influence RMTs’ intention to use SOMs? And Which RMT beliefs contribute most to the factors of the TPB? Settings: The massage therapy (MT) profession of British Columbia, Canada. Participants: Members of the Registered Massage Therapists’ Association of British Columbia (RMTBC). Research Design: An anonymous cross-sectional online survey consisting of multiple-choice questions, Likert-type scale and short answers was used. Main Outcome Measures: Multiple regression analysis of nine TPB items reported construct measures of behavior-related attitudes (BA), normative expectations (SN), control perceptions (PBC), and intention (BI). Thematic analysis of text from two open-ended items enabled the reporting of themes within the data. Results: The combination of BA, SN, and PBC significantly explained 78% of the variance in RMTs’ intention to use SOMs [F(3,203)=239.08, p
