Examining Scottish Chiropractic Professional Identity Using Chiropractic Professional Identity Scales

Overview

This research will examine any potential differences in the professional identity of Scottish chiropractors utilising the Chiropractic Professional Identity Embodiment Scale (CPIES) and the Subtype Orientation Scale (CPISOS). Data will be collected through an online web-based survey. Potential statistical relationships with variables such as age, gender, ethnicity, and previous education on chiropractic professional identity (CPI) will also be explored. This study expands upon prior investigations to further explore the CPI of chiropractic identity internationally. Additionally, the data gleaned from this study could be used as a platform to build understanding and interprofessional relationships within Scotland and, potentially, to aid in working towards greater recognition of chiropractic within Spain. This research could assist Scottish chiropractors in creating better avenues to strengthen their professional identity to help future chiropractors thrive in Europe.

Research Question(s) Using the CPIES and CPISOS, does the strength of chiropractic professional identity (CPI) vary across Scottish chiropractors? For the CPIES and CPISOS, are there any influences on CPI across age, gender, ethnicity, or pre-professional educational variables? Rationale and Significance of the Study By aiming to understand CPI and its drivers, the investigators may be able to strengthen and develop chiropractors' professional identity without homogenisation. A strong professional identity facilitates the taking up of professional responsibilities, promotes a sense of belonging and professional socialisation, increases competence, fosters greater belonging, stability, and esteem, and promotes enhanced decision-making and confidence. These have been shown to enhance trust and patient safety and ultimately lead to better practice and patient outcomes. By better understanding CPI, and through the use of the Chiropractic Professional Identity Embodiment Scale (CPIES) and the Subtype Orientation Scale (CPISOS), the investigators may be able to identify potential divisions or areas of friction in chiropractic curriculum and to better support the profession. Chiropractic research has shown that burnout and professional dissatisfaction may be a consequence of poor professional identity. In a sample of chiropractors, the CPIES and CPISOS may help to identify areas of professional identity that could be strengthened, and that may ultimately improve professional satisfaction and success. This project will also allow us to collect demographic data of Scottish chiropractors, which may also assist in understanding the profession in greater detail and depth. Literature/Past Research Review Simply belonging to a profession does not alone determine one's professional identity; rather, variation exists in beliefs relating to one's occupation. 11 While chiropractic is an established health profession, there is a lack of clarity about the role of chiropractic in healthcare. There is disagreement on what characterises the chiropractic profession, its philosophy, and scope of practice. Chiropractors themselves have reported being challenged at times by the unclear public identity of the profession brought about by contrasting practice styles. Studies exist on chiropractors' attitudes and beliefs on professional identity. In North America, New Zealand, and Australia, pre-chiropractic education and the geographic region have been shown to be associated with differences in professional identity. In North America, chiropractic students report a preference for participating in mainstream health care and a desire to hold to traditional chiropractic theories and practices, being elements of various domains of chiropractic professional identity. Professional identity has been said to begin with formal education and has been researched with undergraduate chiropractic students. Common themes of an interplay between professional association membership status, pre-chiropractic education, and institutional philosophy have been cited as being determining factors in identity construction. Limitations of these current studies exist, the main being that the surveys employed in the research were not psychometrically validated. Additionally, the surveys differed in each study, making generalisability and comparisons difficult. These issues may be remedied through the use of a consistent psychometrically robust scale such as the CPIES. The CPIES was derived through mixed methods research using a qualitative phase that used one-to-one cognitive interviews of 15 expert key informants to inform and develop a pool of 92-candidate items across six known CPI domains. These items were then tested on 231-participants (New Zealand chiropractors and chiropractic students) for psychometric robustness. The final CPIES comprised 22-items and was found to be a valid and reliable measure of CPI. It has been identified that further research is needed to improve the understanding of measurement properties of tools used in research and to aid their selection and use. 25, and this research aims to begin to fill some of these gaps in knowledge. Primary research question: Using the Chiropractic Professional Identity Embodiment Scale (CPIES) and Subtype Orientation Scale (CPISOS), does the strength of chiropractic professional identity (CPI) vary across Scottish chiropractors? Secondary research question: For the Chiropractic Professional Identity Embodiment Scale (CPIES) and Subtype Orientation Scale (CPISOS), are there any influences on chiropractic professional identity (CPI) across age, gender, ethnicity, or pre-professional educational variables? Design of the Study Study design and setting This research is quantitative descriptive study to analyse CPIES and CPISOS questionnaire data across Scottish chiropractors and chiropractic students. The study will be conducted primarily at the Scotland College of Chiropractic. The lead investigator for the project is Dr Alice Cade. Participants All practising Scottish chiropractors and currently enrolled chiropractic students will be invited to take part in this study. Potential participants will not be eligible if they are practising outside of Scotland or enrolled to study chiropractic in an institute outside of Scotland. Procedure Participants will be asked to review the purpose of this study and the participant selection criteria, indicate their agreement to participate, and complete an online web-based survey to rate their beliefs towards 22-CPIES and 21-CPISOS statements and one CPI self-categorisation question on a 5-point Likert scale. The survey is anticipated to take 10 minutes to complete. Data will be anonymous and collected on a platform such as Qualtrics to be analysed by R software. The sample size was based on calculations recommended by Bartlett (2001), where the alpha level a priori at .05, and based on a five-point scale, the level of acceptable error at 3%, and estimated the standard deviation of the scale was 1.25. As the sample size calculated exceeded 5% of the possible population, the available sample size was corrected using Cochran's (1977) formula, resulting in a recommended sample size of 78. There are approximately 90 practising chiropractors and 26 students enrolled at the Scotland College of Chiropractic, and the investigators hope to gain a response from over half of these potential participants, which previous studies have found achievable. Statistical analyses Primary outcomes: A unidimensional score and six sub-scale numerical scores from the Chiropractic Professional Identity Embodiment Scale (CPIES). Secondary outcomes: A unidimensional measurement of chiropractic practitioner subtypes numerical score from the Chiropractic Professional Identity Subtype Orientation Scale (CPISOS). A numerical score from the self-categorisation of chiropractors' professional identity along a philosophical continuum scale. Demographical details will be analysed through descriptive statistics. Pragmatic use of additional statistical analyses between year groups for the CPIES and CPISOS will be used, and various correlations will be investigated for subscale and sum scores. Location The data will be collected online, and the research will be hosted by the Scotland College of Chiropractic.
