Comparing Two Questionnaires for Eliciting CAM Use in a Multi-Ethnic US Population of Older Adults

Exploring the Use of Traditional Medicines, Natural Health Products and Conventional Medicines: Development and Testing of the New Zealand 'All-Medicines' Questionnaire

INTRODUCTION

Traditional, complementary and alternative medicine (TCAM) are popular healthcare choices among consumers globally. The latest national data on the use of TCAM practitioners in New Zealand (NZ) were collected over a decade ago. Robust data on the use of natural health products (NHPs) and TCAM practices alongside conventional medicines are not yet available in NZ.

OBJECTIVES

This study aimed to develop and test a bespoke questionnaire (All-MedsNZ) that included comprehensive data collection elements exploring NHPs' and conventional medicines' use.

METHODS

This was a questionnaire design study involving expert panel feedback, and engagement with TCAM users, in the development process. This work comprised questionnaire development (stage 1) followed by a questionnaire-testing study (stage 2). The questionnaire was developed on the basis of literature review findings and the research team's expertise. The questionnaire content was then validated by an expert panel comprising practitioners in TCAM and conventional medicine. Then, a two-phase study was utilised to test the questionnaire. Phase 1 involved participants (NHP users) completing the web-based questionnaire and providing feedback by answering probing questions added throughout the questionnaire to evaluate users' comprehension of the questions and to identify issues with the questionnaire. In phase 2, selected participants were interviewed online to gain in-depth insights into issues identified in phase one. Based on these findings, the questionnaire was revised.

RESULTS

The expert panel (n = 9) confirmed the questionnaire had high face and content validity; most original questions were retained. In the questionnaire-testing study, 95 and 27 participants completed the phase 1 and 2 studies, respectively. Most questions achieved a high response rate of ≥ 90%, and participants had no major issues understanding and answering the questionnaire. Problematic questions were those relating to providing product barcodes and photographs, and information on product costs. Most of the NHPs data entered by participants included the brand/generic name, manufacturer/company name, main ingredient(s) and dose form. Generally, these NHP-related data were of acceptable quality. However, information on the main ingredient(s) of products entered by participants was less satisfactory: approximately one-third of the 143 NHPs recorded in the study had the main ingredient(s) missing or incorrectly stated. Interviews with participants reiterated the issues identified in the phase 1 study. The low response rates for some of the questions were partly due to participants' unpreparedness (i.e. not having NHPs/medicines on hand) to complete the questionnaire. In addition, a lack of clarity for the term 'natural health practitioner' led to confusion among some participants.

CONCLUSION

Overall, no major design-, method- or questionnaire-related issues were identified in this development and testing work. The questionnaire demonstrated adequate face and content validity and acceptability among participants. The data collected were reasonably complete and of sufficient quality for analysis. Future studies should pilot the revised All-MedsNZ questionnaire with a larger, nationally representative sample to ascertain its feasibility and utility.

The Use of Complementary and Alternative Medicine among Peritoneal Dialysis Patients at a Second-Level Hospital in Yucatán Mexico

BACKGROUND

Complementary and alternative medicine (CAM) is widely used for multiple reasons such as treatment of diseases and their symptoms, empowerment, self-care, disease prevention, dissatisfaction, adverse effects or cost of conventional medicine, perception of compatibility with beliefs, and idiosyncrasy. This study investigated CAM use in patients with chronic kidney disease (CKD) undergoing peritoneal dialysis (PD).

METHODS

A cross-sectional survey study was conducted with 240 eligible patients with CKD in the PD program. By applying the I-CAM-Q-questionnaire, the frequency, level of satisfaction, and reasons for CAM use were explored, and the demographic and clinical data of users and non-users were analyzed. Data analysis included descriptive analysis, Student's t-test, Mann-Whitney U, chi-square, and Fisher tests.

RESULTS

The main types of CAM used were herbal medicine, and chamomile was the most commonly used. To improve the state of well-being was the main reason for use, the attributable benefit of CAM was high, and only a low percentage of users reported side effects. Only 31.8% of the users informed their physicians.

CONCLUSION

The use of CAM is popular among renal patients, and physicians are not adequately informed; in particular, the CAM type ingested represents a risk for drug interactions and toxicity.

Translation and Cross-Cultural Adaptation of the International Questionnaire to Measure the Use of Complementary and Alternative Medicine (I-CAM-Q) for the Polish and Cross-Sectional Study

According to the World Health Organization (WHO), complementary and alternative medicine (CAM) encompasses a broad set of health care practices that are not part of a country's traditional or conventional medicine and are not fully integrated into the prevailing health care system. The aim of this study is the linguistic and cross-cultural adaptation of the Polish version of the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q) and the assessment of the occurrence and factors related to CAM among patients in Poland. A methodological model of translation and cross-cultural adaptation of research tools according to Beaton et al. with a Delphi-Technique was used for the linguistic and cultural adaptation of the Polish version of I-CAM-Q. The Delphi consensus was achieved in the scale assessment between the experts in two rounds (with a score of above 80% of expert agreement). Data was collected using an online survey within 38 thematically different groups on Facebook, among 524 participants. Over half (59.7%, n = 313) of the respondents used the services of at least one CAM practitioner. On the other hand, 50.8% (n = 266) of the respondents declared using physician's advice. The use of herbs and plant products was reported by 84.7% (n = 444), and vitamins and minerals by 88.4% (n = 463) of respondents. The most commonly used self-help practices among the respondents were relaxation techniques (49.6%), praying for one's health (43.3%) and meditation (41.2%). The consensual methodology of validating the Polish version of the I-CAM-Q scale allowed for creation of a conceptually and linguistically equivalent tool with the original international instrument. A high frequency of CAM use was found among the respondents. Therefore, strategies should be implemented to improve patient-physician communication on the use of CAM in Poland.

Complementary and alternative medicines chosen for specific health problems: Internet survey using the I-CAM-Q in Japan: A STROBE-compliant cross-sectional study

This study investigated the different complementary and alternative medicines (CAMs) adopted by people in Japan, as well as the health problems treated with CAMs. Understanding more about this topic will facilitate the appropriate incorporation of CAMs into conventional medicine when treating health problems. Data were collected through an online survey based on the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q). The study examined CAM utilization among people aged 20 years or older; 164 valid responses were collected (18.9%). We adopted a cross-sectional design. We then compared the relationships between the specific health problems reported by participants, their self-help practices, and the kinds of healthcare specialists consulted. We also examined participants' reasons for using CAMs and their responses regarding the usefulness of the CAMs adopted. We found that self-help/CAM practices differed for specific health problems. Participants with musculoskeletal and heart problems were more likely to use poultices. Those with respiratory and digestive problems were more likely to practice yoga, tai chi, and qigong. Those with digestive and neurological problems were more likely to use aromatherapy. The I-CAM-Q questionnaire also revealed the purpose and usefulness of the CAMs utilized as well as the participants' attitudes regarding conventional medicine. The study showed that participants find physicians less helpful than other options for treating their health problems. Additionally, when asked whether it was helpful to consult with a specific professional for health problems, there was a higher percentage of participants who answered "Very helpful" for professionals, like massage, judo, acupuncture, and moxibustion therapists, than for physicians. The results of this study will help to inform medical providers of the most appropriate types of CAMs for dealing with various health problems.

Conventional and complementary health care use and out-of-pocket expenses among Australians with a self-reported mental health diagnosis: a cross-sectional survey

Background

Mental health disorders are a global health concern. In Australia, numerous national reports have found that the current mental healthcare system does not adequately meet the needs of Australians with mental illness. Consequently, a greater understanding of how people with a mental health disorder are using the broader healthcare system is needed. The aim of this paper is to explore conventional and complementary health care use and expenditure among Australian adults reporting a mental health disorder diagnosis.

Methods

A cross-sectional online survey of 2,019 Australian adults examined socio-demographic characteristics, complementary and conventional health care use and the health status of participants.

Results

32 % (n = 641) of the total sample (N = 2019) reported a mental health disorder in the previous 3 years. Of these, 96 % reported consulting a general practitioner, 90.6 % reported using prescription medicines, 42.4 % consulted a complementary medicine practitioner, 56.9 % used a complementary medicine product and 23 % used a complementary medicine practice. The estimated 12-month out-of-pocket health care expenditure among Australians with a mental health disorder was AUD$ 4,568,267,421 (US$ 3,398,293,672) for conventional health care practitioners and medicines, and AUD$ 1,183,752,486 (US$ 880,729,891) for complementary medicine practitioners, products and practices. Older people (50–59 and 60 and over) were less likely to consult a CM practitioner (OR = 0.538, 95% CI [0.373, 0.775]; OR = 0.398, 95% CI [0.273, 0.581] respectively) or a psychologist/counsellor (OR = 0.394, 95% CI [0.243, 0.639]; OR = 0.267, 95% CI [0.160, 0.447] respectively). People either looking for work or not in the workforce were less likely to visit a CM practitioner (OR = 0.298, 95% CI [0.194, 0.458]; OR = 0.476, 95% CI [0.353, 0.642], respectively).

Conclusions

A substantial proportion of Australian adults living with a mental health disorder pay for both complementary and conventional health care directly out-of-pocket. This finding suggests improved coordination of healthcare services is needed for individuals living with a mental health disorder. Research examining the redesign of primary health care provision should also consider whether complementary medicine practitioners and/or integrative health care service delivery models could play a role in addressing risks associated with complementary medicine use and the unmet needs of people living with a mental health disorder.

The INTREST registry: protocol of a multicenter prospective cohort study of predictors of women's response to integrative breast cancer treatment

BACKGROUND

Cancer registries usually assess data of conventional treatments and/or patient survival. Beyond that, little is known about the influence of other predictors of treatment response related to the use of complementary therapies (CM) and lifestyle factors affecting patients' quality and quantity of life.

METHODS

INTREST is a prospective cohort study collecting register data at multiple German certified cancer centers, which provide individualized, integrative, in- and outpatient breast cancer care. Patient-reported outcomes and clinical cancer data of anticipated N = 715 women with pTNM stage I-III breast cancer are collected using standardized case report forms at the time of diagnosis, after completing neo-/adjuvant chemotherapy, after completing adjuvant therapy (with the exception of endocrine therapy) as well as 1, 2, 5, and 10 years after baseline. Endpoints for multivariable prediction models are quality of life, fatigue, treatment adherence, and progression-based outcomes/survival. Predictors include the study center, sociodemographic characteristics, histologic cancer and comorbidity data, performance status, stress perception, depression, anxiety, sleep quality, spirituality, social support, physical activity, diet behavior, type of conventional treatments, use of and belief in CM treatments, and participation in a clinical trial. Safety is recorded following the Common Terminology Criteria for Adverse Events.

DISCUSSION

This trial is currently recruiting participants. Future analyses will allow to identify predictors of short- and long-term response to integrative breast cancer treatment in women, which, in turn, may improve cancer care as well as quality and quantity of life with cancer.

The prevalence of complementary and alternative medicine use in the general population of Babol, North of Iran, 2018

Background

Complementary and Alternative Medicine (CAM) have recently become more popular and accepted worldwide. One principal step to identify the status and organize strategies of CAM is evaluating the manner and the prevalence of its usage among people. This study aimed to investigate the prevalence of CAM modalities usage by the people of Babol, a central city in the North of Iran, in 2018.

Methods

Using the original International CAM Questionnaire (I-CAM-Q), a questionnaire was redesigned in Persian (Farsi) with some changes such as adding special modalities in Iran and its validity and reliability were assessed. Six hundred households were evaluated using a cluster sampling method in 2018 spring by 12 trained interviewers.

Results

Finally, 1770 questionnaires were correctly completed. A total of 110 participants (6.21% of the completed questionnaires) had visited CAM therapists in the last year, 109 persons (6.15%) had received prescriptions from physicians and paramedics to use CAM, and a total of 1032 people (58.30%) used herbs and herbal medicines in the last 12 months. Also, 1265 individuals (71.46%) had used CAM throughout their lives. The most popular methods were herbal medicine (65.76%), Persian Medicine (13.78%), water therapy (10.45%) and music therapy (8.36%). The use of CAM was more popular among women.

Conclusions

The general use of CAM in Babol was similar to other studies, but there were fewer visits by CAM therapists and less frequent adoption of common methods including homeopathy, acupuncture, and energy therapy. It was found that CAM was mostly used for non-serious diseases such as cold and transient gastrointestinal disorders, a pattern that is different from other studies in this field.

Use of complementary and alternative medicine in Norway: a cross-sectional survey with a modified Norwegian version of the international questionnaire to measure use of complementary and alternative medicine (I-CAM-QN)

Background

In recent decades complementary and alternative medicine (CAM) has been widely used worldwide as well as in Norway, where CAM is offered mainly outside the national health care service, mostly complementary to conventional treatment and fully paid for by the patients. With few exceptions, previous research has reported on frequency and associations of total CAM use in Norway rather than on single therapies and products. Therefore, in this present study we will map the use of CAM more precisely, including types of services, products, and self-help practices and further include reasons for use and helpfulness of the specific therapies used based on a modified Norwegian version of the I-CAM-Q (I-CAM-QN).

Method

Computer assisted telephone interviews using I-CAM-QN were conducted with 2001 randomly selected Norwegians aged 16 and above using multistage sampling in January 2019 with age and sex quotas for each area. Weights based on sex, age, education, and region corrected for selection biases, so that results are broadly representative of the Norwegian population. Descriptive statistics were carried out using Pearson’s Chi-square tests and t-tests to identify group differences.

Result

CAM use was reported by 62.2% of the participants during the prior12 months. Most participants had used natural remedies (47.4%), followed by self-help practices (29.1%) and therapies received from CAM providers (14.7%). Few of the participants had received CAM therapies from physicians (1.2%). Women were generally more likely to use CAM than men, younger people more likely than older, and participants with lower university education and income more likely than participants without university education, with higher university education and higher income. Mean number of visits per year to the different CAM providers ranged from 3.57 times to herbalists to 6.77 times to healers. Most of the participants found their use of CAM helpful.

Conclusion

This study confirms that CAM is used by a considerable segment of the Norwegian population. We suspect that the number of participants reporting CAM use is greater when specific therapies are listed in the questionnaire as a reminder (as in the I-CAM-QN) compared to more general questions about CAM use. The CAM modalities used are mainly received from CAM providers operating outside public health care or administered by the participants themselves.

Use of Complementary Medicine in Competitive Sports: Results of a Cross-Sectional Study

BACKGROUND

Although complementary medicine is frequently used in Germany, there is almost no information about complementary medicine use in competitive sports. The aim was to assess the use of complementary medicine among elite athletes in Germany.

PATIENTS AND METHODS

A cross-sectional study among athletes was performed between March 2012 and September 2013. Athletes of both sexes who visited a sports medical outpatient clinic in Munich, Bavaria were included. Data about the use of complementary medicine were collected by means of a standardized measurement instrument, the German version of the international complementary and alternative medicine questionnaire.

RESULTS

Of the 334 athletes (female 25%, mean age 20.2 ± 6.6 years) who completed all 4 sections of the questionnaire, 69% reported the use of at least one type of complementary medicine within the last 12 months. 505 athletes (female 26%, mean age 20.5 ± 7.0 years) completed at least one section of the questionnaire entirely. Within 12 months, the osteopath (11%), herbal medicine (17%), vitamins/minerals (32%), and relaxation techniques (15%) were the most frequently visited/used in relation to the respective sections of the questionnaire.

CONCLUSION

Complementary medicine is frequently used by athletes in Germany. The efficacy, safety, and costs of complementary medicine should be investigated in clinical trials among athletes in the future.

Use of complementary medicine products: a nationally representative cross-sectional survey of 2019 Australian adults

OBJECTIVES

To provide a contemporary description of complementary medicine (CM) product use in Australia.

DESIGN

Cross-sectional survey.

SETTING

Online.

PARTICIPANTS

A nationally representative sample (n=2019) of the Australian adult population.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcomes measures included the use and type of CM products used, and source of recommendation. Secondary measures included disclosure of CM product use to health practitioners, concomitant use of pharmaceuticals and predictors of use.

RESULTS

Prevalence of CM product use was 50.3%, with the most frequently used being vitamin and mineral supplements (VMSs; 47.8%) and homoeopathic medicines the least used (6.8%). A majority of respondents using CM products were also using pharmaceutical products, and small but significant associations were found between the use of CM products and pharmaceuticals (p<0.05). Small statistically significant associations were found between use of vitamin products and disclosure of use to general practitioners (GPs; Cramer's V=0.13, p=0.004) and hospital doctors (Cramer's V=0.11, p=0.04), and between use of herbal medicines and disclosure to both GPs (Cramer's V=0.11, p=0.02) and hospital doctors (Cramer's V=0.12, p=0.03). Women, those with higher education and those with no private health insurance were more likely to use CM products (p<0.05), while those without chronic conditions were less likely to use CM products (p<0.05) (χ2(29)=174.70, p<0.001).

CONCLUSIONS

The number of Australians using CM products has remained relatively stable and substantial for nearly two decades. The majority of CM use relates to VMSs. Given the number of Australians using both CM products and pharmaceutical medicines, it is important to evaluate the potential clinical implications of such practices to ensure safe, effective and coordinated health policy and patient care.

The prevalence, characteristics, expenditure and predictors of complementary medicine use in Australians living with gastrointestinal disorders: A cross-sectional study

AIMS

To determine the prevalence, characteristics, expenditure and predictors of complementary medicine (CM) use in Australian adults living with gastrointestinal disorders (GID).

METHODS

A cross-sectional study involving 2,025 Australian adults was conducted. Participants were recruited through purposive convenience sampling. Descriptive statistics were conducted to report the prevalence of people living with GIDs and their CM use, including CM products, mind-body practices and CM practitioner services. Chi-square test and independent-samples t-test were used to determine the associations between sociodemographic or health-related variables with CM use. Binary logistic regression was conducted to determine the significant predictors of CM use in GID participants. Economic data was calculated based on the mean out-of-pocket expenditure on CM.

RESULTS

Of the 293 participants reporting a GID, 186 (63.5%) used CM products, 55 (18.8%) used a mind-body practice and 141 (48.1%) visited at least one CM practitioner in the last 12 months. Collectively, the majority of GID participants using any type of CM were female, aged 40-49 years, married and employed. The mean score for health-related quality of life was 49.6 out of 100 in GID participants and 68.2 in participants without a GID (p < 0.001). Average annual out-of-pocket expenditure on CM products was AUD127.29 by CM products users with a GID. The predictors of CM products, mind-body practices and CM practitioner services use differed. Of the 111 CM product users with a GID, 103 (92.8%) disclosed all or some of their CM use to general practitioner, 89 (80.2%) to specialist doctor, 79 (71.2%) to pharmacist and 69 (62.1%) to hospital doctor.

CONCLUSIONS

A substantial proportion of Australian adults living with GID use CM products, mind-body practices and CM practitioner services. This study provides important insights to inform and guide the development of a more coordinated health care services for individuals living with GID.

Complementary medicine use in the Australian population: Results of a nationally-representative cross-sectional survey

In order to describe the prevalence and characteristics of complementary medicine (CM) practice and product use by Australians, we conducted a cross-sectional online survey with Australian adults aged 18 and over. Rates of consultation with CM practitioners, and use of CM products and practices were assessed. The sample (n = 2,019) was broadly representative of the Australian population. Prevalence of any CM use was 63.1%, with 36% consulting a CM practitioner and 52.8% using any CM product or practice. Bodywork therapists were the most commonly consulted CM practitioners (massage therapists 20.7%, chiropractors 12.6%, yoga teachers 8.9%) and homeopaths were the least commonly consulted (3.4%). Almost half of respondents (47.8%) used vitamin/mineral supplements, while relaxation techniques/meditation were the most common practice (15.8%). CM users were more likely to be female, have a chronic disease diagnosis, no private health insurance, a higher education level, and not be looking for work. Prevalence of CM use in Australia has remained consistently high, demonstrating that CM is an established part of contemporary health management practices within the general population. It is critical that health policy makers and health care providers acknowledge CM in their attempts to ensure optimal public health and patient outcomes.

An assessment of the use of complementary and alternative medicine by Korean people using an adapted version of the standardized international questionnaire (I-CAM-QK): a cross-sectional study of an internet survey

Background

In Korea, there are two types of medical doctors: one practises conventional medicine (hereafter called a physician), and the other practises traditional medicine (hereafter called a Korean medical doctor). This study aimed to compare the provision of complementary and alternative medicine (CAM) by these providers to CAM use per self-judgement in Korea.

Methods

We analysed 1668 Korean people via an internet survey with the Korean adopted version of the I-CAM-Q, namely, the International Questionnaire to measure use of CAM, to understand whether respondents used CAM based either on a prescription or advice from a physician or a Korean medical doctor or on self-judgement.

Results

In the previous 12 months, the proportions of respondents who were treated by a physician, who were treated by a Korean medical doctor and who were not treated by anyone were 67.9, 20.7 and 14.2%, respectively. Among the respondents who received CAM based on a prescription or advice from a physician, traditional Korean medicine practices and dietary supplements were commonly used; only a small percentage used other CAM therapies. Respondents who received CAM based on a prescription or advice from a Korean medical doctor showed similar results. Acupuncture and moxibustion, traditional Korean medicines (decoction), or cupping were more commonly used. Korean traditional medicines as over-the-counter (OTC) drugs were more commonly used by respondents who received CAM therapy based on a prescription or advice from a physician than by those who received CAM therapy based on a prescription or advice from a Korean medical doctor. A total of 74% of the responders used any CAM by self-judgement in the previous 12 months.

Conclusions

For the use of CAM in Korea, in addition to the Korean traditional medical care provided by Korean medical doctors, general physicians advised people regarding Korean traditional medical care and dietary supplements.

The I-CAM-FR: A French Translation and Cross-Cultural Adaptation of the I-CAM-Q

Background: The use of complementary and alternative medicine (CAM) is growing every year. The extent of its use is still not clear, and it is difficult to undertake comparative studies due to the variety of data collection tools used. Therefore, a standardized International Complementary and Alternative Medicine Questionnaire (I-CAM-Q) has been recommended to determine data about its usage. The purpose of the present study is to present a controlled translation of the questionnaire into French which is also properly adapted to a French audience. Methods: The English-written questionnaire, the I-CAM-Q, was submitted to three independent translators. Each translator produced a separate French translation (FT.1.1, FT.1.2, FT.1.3) that was then synthesized into a unique new version (FT.2.0). Version FT.2.0 was then submitted to three new translators, who translated them back to three distinct English versions (BT.1.1, BT.1.2, BT.1.3). These versions were once again synthesized in a unique questionnaire (BT.2.0). The version BT.2.0 was then submitted to an expert committee that compared it to the original I-CAM-Q in order to review the process and adapt FT.2.0 according to differences between the I-CAM-Q and BT.2.0. This led to a revised French version, PT.0.0. Version PT.0.0 was then tested with the use of cognitive interviews. These interviews allowed a final adjustment of the translations to produce a definitive version in French: the I-CAM-FR. Results: Four French translations and four versions in English of the I-CAM-Q questionnaire were produced. This allowed us to present a consolidated French translation to an expert committee. Their adjustments were taken into account before testing the final French-translated questionnaire on a group of people (n = 10) representing a diverse sample of the French population. The expert committee then suggested changes according to the errors due to the translation process sought out by the pre-tests, and recommendations based on the errors that were not due to the translation process. Conclusions: Through a rigorous methodology, we produced a French translation and a cross-cultural adaptation of the I-CAM-Q questionnaire. This work has led to the creation of an equivalent questionnaire available for use in France, the I-CAM-FR.

The Complementary Health Approaches for Pain Survey (CHAPS): Validity testing and characteristics of a rural population with pain

Objectives

Little is known about patterns and correlates of Complementary Health Approaches (CHAs) in chronic pain populations, particularly in rural, underserved communities. This article details the development and implementation of a new survey instrument designed to address this gap, the Complementary Health Approaches for Pain Survey (CHAPS).

Design

Following pilot-testing using pre-specified criteria to assess quality and comprehension in our target population, and after feedback regarding face-validity from content experts and stakeholders, the final cross-sectional self-report survey required 10–12 minutes to complete. It contained 69 demographic, lifestyle and health-related factors, and utilized a Transtheoretical Model (TTM) underpinning to assess short- and long-term use of 12 CHAs for pain management. Twenty additional items on pain severity, feelings, clinical outcomes, and activities were assessed using the Short-Form Global Pain Scale (SF-GPS); Internal reliability was assessed using Cronbach’s alpha.

Settings/location

Investigators conducted consecutive sampling in four West Virginia pain management and rheumatology practices.

Participants

301 Appalachian adult patients seeking conventional care for pain management.

Results

Response rates were high (88% ± 4.1%). High quality and comprehension deemed the CHAPS an appropriate measurement tool in a rural population with pain. Missing data were unrelated to patient characteristics. Participants predominantly experienced chronic pain (93%), had five or more health conditions (56%, Mean = 5.4±3.1), were white (92%), female (57%), and middle-aged (Mean = 55.6 (SD = 13.6) years). Over 40% were disabled (43%) and/or obese (44%, Mean BMI = 33.4±31.5). Additionally, 44% used opioids, 31% used other prescription medications, and 66% used at least one CHA for pain, with 48% using CHAs for greater than 6 months. There was high internal reliability of the SF-GPS (alpha = .93) and satisfactory internal reliability for each of the five TTM stages across (all) twelve CHAs: precontemplation (0.89), contemplation (0.72), preparation (0.75), action (0.70), and maintenance (0.70).

Conclusions

The CHAPS is the first comprehensive measurement tool to assess CHA use specifically for pain management. Ease of administration in a population with pain support further use in population- and clinic-based studies in similar populations.

Development and evaluation of the R-I-CAM-Q as a brief summative measure of CAM utilisation

OBJECTIVE

This study evaluates a revised version of the I-CAM-Q, the R-I-CAM-Q, which is a shorter scale, and suitable for use as a brief, summative measure of CAM utilisation.

DESIGN

Online survey with an Australian sample (n=2697).

ANALYSIS

The psychometric properties of the I-CAM-Q were analysed using Mokken Scaling Analysis and Structural Equation Modelling.

RESULTS

A subset of items were identified as having an adequate uni-dimensional structure that can be aggregated to yield a scalar measure of CAM utilisation. Certain items, including prayer for health purposes, and chiropractic, were not indicative of general CAM use.

CONCLUSIONS

The R-I-CAM-Q provides a unitary, aggregate measure of CAM utilisation that provides scope for replicable research into the determinants of CAM use. It is the first quantitative and summative measure of general CAM use, developed and tested using modern psychometric methods.

Analysis of Multiple Partially Ordered Responses to Belief Items with Don't Know Option

Understanding beliefs, values, and preferences of patients is a tenet of contemporary health sciences. This application was motivated by the analysis of multiple partially ordered set (poset) responses from an inventory on layman beliefs about diabetes. The partially ordered set arises because of two features in the data-first, the response options contain a Don't Know (DK) option, and second, there were two consecutive occasions of measurement. As predicted by the common sense model of illness, beliefs about diabetes were not necessarily stable across the two measurement occasions. Instead of analyzing the two occasions separately, we studied the joint responses across the occasions as a poset response. Few analytic methods exist for data structures other than ordered or nominal categories. Poset responses are routinely collapsed and then analyzed as either rank ordered or nominal data, leading to the loss of nuanced information that might be present within poset categories. In this paper we developed a general class of item response models for analyzing the poset data collected from the Common Sense Model of Diabetes Inventory. The inferential object of interest is the latent trait that indicates congruence of belief with the biomedical model. To apply an item response model to the poset diabetes inventory, we proved that a simple coding algorithm circumvents the requirement of writing new codes such that standard IRT software could be directly used for the purpose of item estimation and individual scoring. Simulation experiments were used to examine parameter recovery for the proposed poset model.

Use of Traditional and Complementary Medicine as Self-Care Strategies in Community Health Centers: Cross-Sectional Study in Urban Pearl River Delta Region of China

In China, Community Health Centers (CHCs) are major providers of primary care services, but their potential in empowering patients' self-management capacity has not been assessed. This study aims to describe self-care practice patterns amongst CHC attendees in urban China.In this cross-sectional quantitative study, 3360 CHC patients from 6 cities within the Pearl Delta Region were sampled using multistage cluster sampling.Thirty-seven per cent had used with over-the-counter Chinese herbal medicines (OTC CHMs) in the past year and majority of respondents found OTC CHMs effective. OTC CHMs were more popular amongst those who needed to pay out of pocket for CHC services. Less than 10% used vitamins and minerals, and those with a lower socioeconomic background have a higher propensity to consume. Although doubts on their usefulness are expressed, their use by the vulnerable population may reflect barriers to access to conventional health care, cultural affinity, or a defense against negative consequences of illnesses. About 25% performed physical exercise, but the prevalence is lower amongst women and older people. Taiji seems to be an alternative for these populations with promising effectiveness, but overall only 6% of CHC attendees participated.These results suggest that CHCs should start initiatives in fostering appropriate use of OTC CHM, vitamins, and minerals. Engaging community pharmacists in guiding safe and effective use of OTC CHM amongst the uninsured is essential given their low accessibility to CHC services. Prescription of Taiji instead of physical exercises to women and older people could be more culturally appropriate, and the possibility of including this as part of the CHC services worth further exploration.

Translation and cross-cultural adaptation of a standardized international questionnaire on use of alternative and complementary medicine (I-CAM - Q) for Argentina

Background

The widespread and growing use of alternative and complementary medicine (CAM) worldwide has been thoroughly described. In Argentina the limited information on the use of CAM has been reported between 40 and 55 %. However, the rate of use is extremely variable worldwide. For this purpose the international questionnaire on the use of complementary and alternative medicines (I-CAM - Q), was developed. The implementation of a translated and cross-culturally adapted version of the questionnaire would allow for a reliable and standardized evaluation of the rate of use of CAM in Argentina. It would be a great step towards improving what we know about the healing habits of our population.

Methods

The forward and back-translation method was used. Four translators were involved. A committee was commissioned to reconcile the different versions. The process of cross-cultural adaptation was made by consulting 17 alternative and complementary medicine experts using the DELPHI method. The retrieved questionnaire was evaluated in 18 patients sampled by convenience (9 men, different educational and self-reported health levels). The interviews consisted of three parts: an initial demographics questionnaire; the administration of the I-CAM-Q and finally the cognitive interview, which included reviewing the questionnaire and reexamining questions that generated doubts during the interview. The comprehension of the questions was also evaluated. As a last step, using the information obtained from the interviews, the final version of the questionnaire was drafted.

Results and conclusion

The questionnaire seems to have been accepted by most patients during the interviews. Conflictive elements that emerged did not seem to have an impact on its administration. The flexibility of the questionnaire allowed to add professionals and practices which contributed to a more accurate local adaptation. Further research should focus on assessing the questionnaire’s psychometric performance and validity, which so far has not been done.

Unreliable item or inconsistent person? A study of variation in health beliefs and belief-anchors to biomedical models

The reliability of an item designed to measure health belief is often confounded with response consistency at the person level. The study applied contemporary measurement methods to an inventory of common sense beliefs about diabetes and used a sample of N = 563 adults with diabetes to test the hypothesis that individuals whose beliefs are congruent with a biomedical model are more consistent in their responses. Item-level analysis revealed that the domains of Causes and Medical Management were the least reliable. Person-level analysis showed that respondents who held views congruent with the biomedical model were more consistent than people who did not.

The use of and out-of-pocket spending on complementary and alternative medicine in Qassim province, Saudi Arabia

BACKGROUND AND OBJECTIVES

The current picture of the Saudis' use of complementary and alternative medicine (CAM) has not yet been developed. The aim of this study was to assess the feasibility of using the international questionnaire to measure use of complementary and alternative medicine (I-CAM-Q) in Saudi Arabia to evaluate the use of and out-of-pocket spending on CAM.

DESIGN AND SETTINGS

It was a cross-sectional study, conducted in 2011, in primary health care centers in Qassim.

METHODS

In a multistage sampling technique, 12 primary health care centers were selected randomly in the Al-Qassim province in Saudi Arabia. From each center, 100 attendants were interviewed for a total of 1160 completed questionnaires.

RESULTS

A total of 74% of subjects had visited CAM providers in 12 months before the survey. This percentage decreased to 47.6% when spiritual healers were excluded. The specific CAM providers who were visited were spiritual healers (26.7%), herbalists (23.2%), providers of honeybee products (14.9%), and hijama (wet cupping; 13%). Chronic illnesses were the main reason for the visits. A total of 50% of subjects were satisfied with their visit. Physicians were the providers of CAM for 11.3% of the participants. More than 75% of the subjects used herbs in the previous 12 months for medical and health reasons, while only 25% used vitamins or minerals. Self-help was used in 26% of the participants. Relaxation (10.3%) was the most common self-CAM practice followed by meditation (6.7%). The subjects spent 350000 (US$) on CAM visits and 300000 (US$) purchasing CAM products.

CONCLUSIONS

I-CAM-Q can be used in different populations and cultures in the East including Saudi Arabia after customization to overcome its limitations, as the questionnaire was developed in Western societies.

Integrating traditional chinese medicine services in community health centers: insights into utilization patterns in the pearl river region of china

In China's healthcare reform, community health centers (CHCs) are designed to take a pivotal role in providing primary care. Whilst about 20% of all outpatient care in China is delivered by the traditional Chinese medicine (TCM) sector, hospitals, instead of CHCs, are major providers. Using current patterns of patient utilization this study aims to inform CHCs on how they may strengthen access to TCM services. Three thousand three hundred and sixty CHC patients from six cities within the urban Pearl Delta Region were enumerated using multistage cluster sampling. Fifty-two percent had visited herbalists within three months with a mean visit frequency of 1.50 times. Herbal treatments, which are cheaper than western medicines, were more popular amongst those who needed to pay out of pocket including the uninsured. Herbal medicines appeared to be an alternative for those who are underinsured. Acupuncturists and massage therapists were visited by smaller proportions, 6.58% and 5.98%, respectively, with a mean three-month visit of 0.27 and 0.26 times. Access was restricted by lack of social insurance coverage. Whilst increasing provision of TCM in CHCs might respond to patient demand, increasing insurance coverage for TCM needs to be evaluated using current evidence on safety and effectiveness.

Translation and adaptation of an international questionnaire to measure usage of complementary and alternative medicine (I-CAM-G)

BACKGROUND

The growing body of data on prevalence of complementary and alternative medicine (CAM) usage means there is a need to standardize measurement on an international level. An international team has published a questionnaire (I-CAM-Q), but no validation has yet been provided. The aim of the present study was to provide a German measurement instrument for CAM usage (I-CAM-G) which closely resembles the original English version, and to assess it's performance in two potential samples for measuring CAM usage.

METHODS

The English I-CAM-Q questionnaire was translated into German, and adapted slightly. The resulting I-CAM-G questionnaire was then pre-tested on 16 healthy volunteers, and 12 cognitive interviews were carried out. The questionnaire was employed in a sample of breast cancer patients (N = 92, paper and pencil), and a sample from the general population (N = 210, internet survey). Descriptive analyses of items and missing data, as well as results from the cognitive interviews, are presented in this paper.

RESULTS

The translated questionnaire had to be adapted to be consistent with the German health care system. All items were comprehensible, whereby some items were unambiguous (e.g. CAM use yes/no, helpfulness), while others gave rise to ambiguous answers (e.g. reasons for CAM use), or high rates of missing data (e.g. number of times the CAM modality had been used during the last 3 months). 78% of the breast cancer patients and up to 85% of a sample of the general population had used some form of CAM.

CONCLUSIONS

Following methodologically sound and comprehensive translation, adaptation and assessment processes using recognized translation procedures, cognitive interviews, and studying the performance of the questionnaire in two samples, we arrived at a German questionnaire for measuring CAM use which is comparable with the international (English) version. The questionnaire appropriately measures CAM use, with some items being more appropriate than others. We recommend the development of a short version.

A pilot feasibility study of a questionnaire to determine European Union-wide CAM use

BACKGROUND

No questionnaire specifically measuring the core components of complementary and alternative medicine (CAM) use has been validated for use across European Union (EU) countries. We aimed to determine the face validity, acceptability and the participants' comprehension of a pre-existing questionnaire designed to measure 'CAM use', to provide a comparative, standardised questionnaire for use by health care providers, policy makers and purchasers throughout Europe.

METHODS

Established procedures were employed to translate the questionnaire into 4 EU languages. The translated questionnaires were piloted on 50 healthy adults from each country who may never have used CAM. 10 participants per country also took part in audio-recorded think aloud interviews about the questionnaire. The interviews were transcribed and analysed in the language in which they were conducted; findings were summarised in English. Questionnaire data were pooled across countries, and patterns of completion and missing data were analysed.

RESULTS

The questionnaire was translated into Italian, Spanish, Dutch and Romanian. The mean age of the participants was 43.6 years. 34% were male, 87.4% were either light or heavy CAM users, and 12.6% were non-users. Qualitative analysis identified common problems across countries including a 'hard-to-read' layout, misunderstood terminology and uncertainty in choosing response options. Quantitative analysis confirmed that a substantial minority of respondents failed to follow questionnaire instructions and that some questions had substantial rates of missing data.

CONCLUSIONS

The I-CAM-Q has low face validity and low acceptability, and is likely to produce biased estimates of CAM use if applied in England, Romania, Italy, The Netherlands or Spain. Further work is required to develop the layout, terms, some response options and instructions for completion before it can be used across the EU.

FBAT-SNP-PC: an approach for multiple markers and single trait in family-based association tests

OBJECTIVE

Develop a new test for family-based association studies and continuous traits that incorporates power- enhancing techniques from two existing testing strategies.

METHODS

The new procedure initiates with an extraction of the relevant information from the variability of the genotypes and an assessment of the approximate individual markers effects and their directions. This information is incorporated in the construction of the actual test statistic through a selection of a data-determined number of optimal linear combinations of the offspring genotypes which, in a power enhancing step, are consequently combined into a single degree of freedom test. We conduct a comparison simulation study in which the performance of the new test is contrasted with the test that is currently known to offer the highest overall power, FBAT-LC.

RESULTS

The new test has an overall performance very similar to that of FBAT-LC but attains higher power in candidate genes with lower average pairwise correlations and moderate to high allele frequencies with large gains (up to 80%) for some of the analyzed genes possessing the above-mentioned characteristics.

CONCLUSION

The new test is a promising tool for candidate gene studies with substantial power gains for genes that are characterized by SNPs with low mean pairwise correlation.
