Barriers to the conduct and application of research among complementary and alternative medicine professions in Australia and New Zealand: A cross-sectional survey

INTRODUCTION

Despite the growing international popularity and use of complementary and alternative medicine (CAM), the uptake of evidence-based practice (EBP) in CAM has been slow. This cross-sectional survey aimed to further our understanding of the factors impacting EBP uptake in CAM.

METHODS

The 32-item oBSTACLES instrument was administered online using the SurveyMonkey™platform. The survey evaluated barriers to both the conduct and application of research among CAM practitioners and researchers, from multiple CAM disciplines across Australia and New Zealand. Participants were recruited via practice-based research networks, professional associations, CAM educational institutions, CAM research centres, pertinent product manufacturers and social media platforms. Data were analysed using descriptive statistics.

RESULTS

Six hundred and eighty-two CAM stakeholders responded to the survey. Barrier items were divided into two interlinked constructs, "capacity" and "culture". Capacity related to issues regarding access, competency, bias, incentives, and time, whereas culture related to values and complex systems. Under capacity, the greatest proportion of participants (>70 %) agreed that access was a barrier to the conduct and application of research, including lack of funding, institutional support, research training and collaborations. In terms of culture, the majority of participants (>60 %) agreed that values were a barrier to research conduct and application, including limited undergraduate research opportunities and diverse views of evidence.

CONCLUSION

Findings from this research suggest a multitude of barriers negatively impact the conduct and application of research in CAM. Insights gained from this research will be instrumental in developing actionable strategies aimed at mitigating the impact of these barriers to improve research engagement in CAM.

Use of GFCF Diets in Children with ASD. An Investigation into Parents' Beliefs Using the Theory of Planned Behaviour

Gluten free/Casein free (GFCF) diets are one of the most common types of Complementary and Alternative Medicines (CAM) used in Autism Spectrum Disorders (ASD) despite little evidence to support positive effects. There has been no theory driven literature that has investigated parent’s reasons for their use. The Theory of Planned Behaviour (TPB) was used to examine parent’s intentions to use GFCF diets for their child with an ASD. Treatment and causal beliefs were also examined. Parents (n = 33, children aged 3–17 years) were influenced by anticipated regret, positive outcomes and attitude. Future interventions should provide information to parents and health professionals about the possible causes of ASD and therapy options which are in line with current recommendations.

Complementary and alternative medicine use for headache and migraine: a critical review of the literature

CONTEXTS: An evidence base for complementary and alternative medicine (CAM) consumption within general populations is emerging. However, research data on CAM use for headache disorders remain poorly documented. This paper, constituting the first critical review of literature on this topic, provides a synopsis and evaluation of the research findings on CAM use among patients with headache and migraine.

METHODS

A comprehensive search of literature from 2000 to 2011 in CINAHL, MEDLINE, AMED, and Health Sources was conducted. The search was confined to peer-reviewed articles published in English reporting empirical research findings of CAM use among people with primary headache or migraine.

RESULTS

The review highlights a substantial level of CAM use among people with headache and migraine. There is also evidence of many headache and migraine sufferers using CAM concurrent to their conventional medicine use. Overall, the existing studies have been methodologically weak and there is a need for further rigorous research employing mixed method designs and utilizing large national samples.

DISCUSSION

The critical review highlights the substantial prevalence of CAM use among people with headache and migraine as a significant health care delivery issue, and health care professionals should be prepared to inquire and discuss possible CAM use with their patients during consultations. Health care providers should also pay attention to the possible adverse effects of CAM or interactions between CAM and conventional medical treatments among headache and migraine patients.

Development and Validation of an Instrument for Measuring Attitudes and Beliefs about Complementary and Alternative Medicine (CAM) Use among Cancer Patients

Despite cancer patients' extensive use of complementary and alternative medicine (CAM), validated instruments to measure attitudes, and beliefs predictive of CAM use are lacking. We aimed at developing and validating an instrument, attitudes and beliefs about CAM (ABCAM). The 15-item instrument was developed using the theory of planned behavior (TPB) as a framework. The literature review, qualitative interviews, expert content review, and cognitive interviews were used to develop the instrument, which was then administered to 317 outpatient oncology patients. The ABCAM was best represented as a 3-factor structure: expected benefits, perceived barriers, and subjective norms related to CAM use by cancer patients. These domains had Eigenvalues of 4.79, 2.37, and 1.43, and together explained over 57.2% of the variance. The 4-item expected benefits, 7-item perceived barriers, and 4-item subjective norms domain scores, each had an acceptable internal consistency (Cronbach's alpha) of 0.91, 0.76, and 0.75, respectively. As expected, CAM users had higher expected benefits, lower perceived barriers, and more positive subjective norms (all P < 0.001) than those who did not use CAM. Our study provides the initial evidence that the ABCAM instrument produced reliable and valid scores that measured attitudes and beliefs related to CAM use among cancer patients.

Attitudes towards complementary and alternative medicine in chronic pain syndromes: a questionnaire-based comparison between primary headache and low back pain

Background

Complementary and Alternative Medicine (CAM) is widely used and popular among patients with primary headache or low back pain (LBP). Aim of the study was to analyze attitudes of headache and LBP patients towards the use of CAM.

Methods

Two questionnaire-based surveys were applied comparing 432 primary headache and 194 LBP patients.

Results

In total, 84.75% of all patients reported use of CAM; with significantly more LBP patients. The most frequently-used CAM therapies in headache were acupuncture (71.4%), massages (56.4%), and thermotherapy (29.2%), in LBP thermotherapy (77.4%), massages (62.7%), and acupuncture (51.4%). The most frequent attitudes towards CAM use in headache vs. LBP: "leave nothing undone" (62.5% vs. 52.1%; p = 0.006), "take action against the disease" (56.8% vs. 43.2%; p = 0.006). Nearly all patients with previous experience with CAM currently use CAM in both conditions (93.6% in headache; 100% in LBP). However, the majority of the patients had no previous experience.

Conclusion

Understanding motivations for CAM treatment is important, because attitudes derive from wishes for non-pharmacological treatment, to be more involved in treatment and avoid side effects. Despite higher age and more permanent pain in LBP, both groups show high use of CAM with only little specific difference in preferred methods and attitudes towards CAM use. This may reflect deficits and unfulfilled goals in conventional treatment. Maybe CAM can decrease the gap between patients' expectations about pain therapy and treatment reality, considering that both conditions are often chronic diseases, causing high burdens for daily life.

How parents choose to use CAM: a systematic review of theoretical models

BACKGROUND

Complementary and Alternative Medicine (CAM) is widely used throughout the UK and the Western world. CAM is commonly used for children and the decision-making process to use CAM is affected by numerous factors. Most research on CAM use lacks a theoretical framework and is largely based on bivariate statistics. The aim of this review was to identify a conceptual model which could be used to explain the decision-making process in parental choice of CAM.

METHODS

A systematic search of the literature was carried out. A two-stage selection process with predetermined inclusion/exclusion criteria identified studies using a theoretical framework depicting the interaction of psychological factors involved in the CAM decision process. Papers were critically appraised and findings summarised.

RESULTS

Twenty two studies using a theoretical model to predict CAM use were included in the final review; only one examined child use. Seven different models were identified. The most commonly used and successful model was Andersen's Sociobehavioural Model (SBM). Two papers proposed modifications to the SBM for CAM use. Six qualitative studies developed their own model.

CONCLUSION

The SBM modified for CAM use, which incorporates both psychological and pragmatic determinants, was identified as the best conceptual model of CAM use. This model provides a valuable framework for future research, and could be used to explain child CAM use. An understanding of the decision making process is crucial in promoting shared decision making between healthcare practitioners and parents and could inform service delivery, guidance and policy.

Consumer Decision Factors for Initial and Long-Term Use of Complementary and Alternative Medicine

Guided by the conceptual framework of the consumer decision-making model, the present study compared the factors associated with initial and long-term use of complementary and alternative medicine (CAM) providers. A survey was completed by 239 people recruited from the offices of physicians and CAM practitioners. Conventional medicine clients ( n = 54), new or infrequent clients ( n = 73), and established CAM clients ( n = 112) were compared to identify the decision factors for initial and long-term CAM use. Consistent with the components of this model, we found support for the roles of external influences (age, social recommendations), decision process factors (symptom severity, egalitarian provider preference), and post-decision factors (dissatisfaction with conventional care) depending on whether the pattern of CAM use was new or infrequent or established. Overall, this study provides preliminary support for the utility of the consumer decision-making model as an integrative framework for understanding the roles of correlates of CAM use.
