Objectives: Existing studies on the use of complementary and alternative medicine (CAM) have produced diverse results regarding the types and prevalence of CAM use due, in part, to variations in the measurement of CAM modalities. A questionnaire that can be adapted for use in a variety of populations will improve CAM utilization measurement. The purposes of this article are to (1) articulate the need for such a common questionnaire; (2) describe the process of questionnaire development; (3) present a model questionnaire with core questions; and (4) suggest standard techniques for adapting the questionnaire to different languages and populations. Methods: An international workshop sponsored by the National Research Center in Complementary and Alternative Medicine (NAFKAM) of the University of Tromsø, Norway, brought CAM researchers and practitioners together to design an international CAM questionnaire (I-CAM-Q). Existing questionnaires were critiqued, and working groups drafted content for a new questionnaire. A smaller working group completed, tested, and revised this self-administered questionnaire. Results: The questionnaire that was developed contains four sections concerned with visits to health care providers, complementary treatments received from physicians, use of herbal medicine and dietary supplements, and self-help practices. A priori-specified practitioners, therapies, supplements, and practices are included, as well as places for researcher-specified and respondent-specified additions. Core questions are designed to elicit frequency of use, purpose (treatment of acute or chronic conditions, and health maintenance), and satisfaction. A penultimate version underwent pretesting with ''think-aloud'' techniques to identify problems related to meaning and format. The final questionnaire is presented, with suggestions for testing and translating. Conclusions: Once validated in English and non-English speaking populations, the I-CAM-Q will provide an opportunity for researchers to gather comparable data in studies conducted in different populations. Such data will increase knowledge about the epidemiology of CAM use and provide the foundation for evidence-based comparisons at an international level.

BackgroundSelf-reported use of Complementary and Alternative Medicine (CAM) varies widely from 10% to 75% in the general populations worldwide. When limited to use of a CAM provider 2% to 49% reported use is found. CAM use is believed to be closely associated with socio demographic variables such as gender, age, education, income and health complaints. However, studies have only occasionally differentiated CAM use according to gender. Therefore, the aim of the study presented here is to describe the prevalence of CAM use on the background of gender and to describe the specific characteristics of male and female users in the total Tromsø 6 population.MethodsA total of 12,982 men and women aged 30–87 in the municipality of Tromsø, Norway went through a health screening program and completed two self-administered questionnaires in 2007/2008. The questionnaires were developed specifically for the Tromsø study and included questions about life style and health issues in addition to socio demographic variables.ResultsA total of 33% of the participants reported use of any CAM within the last 12 months, women more often than men (42% and 24%, respectively). When limited to visits to a CAM provider, we found 17% use among women and 8% among men. The relationship between the demographic variables and being a CAM user differed significantly between men and women with regard to age, household income, and marital status. We did not find significant differences between men and women concerning education and self-reported health.ConclusionsFindings from this study suggest that the prevalence and associations for use of CAM differ between men and women concerning several socio demographic variables (age, education and household income). Neglect of women’s health care needs in public health care may contribute to the fact that women to a higher degree than men turn to CAM and CAM products.

Background and objectives: Self-reported use of complementary and alternative medicine (CAM) among patients varies widely between studies, possibly because the definition of a CAM user is not comparable. This makes it difficult to compare studies. The aim of this study is to present a six-level model for classifying patients' reported exposure to CAM. Prayer, physical exercise, special diets, over-the-counter products/CAM techniques, and personal visits to a CAM practitioner are successively removed from the model in a reductive fashion. Methods: By applying the model to responses given by Norwegian patients with cancer, we found that 72% use CAM if the user was defined to include all types of CAM. This proportion was reduced successively to only 11% in the same patient group when a CAM user was defined as a user visiting a CAM practitioner four or more times. When considering a sample of 10 recently published studies of CAM use among patients with breast cancer, we found 98% use when the CAM user was defined to include all sorts of CAM. This proportion was reduced successively to only 20% when a CAM user was defined as a user of a CAM practitioner. Conclusions: We recommend future surveys of CAM use to report at more than one level and to clarify which intensity level of CAM use the report is based on.

BackgroundIn Northern Norway, traditional medicine (TM) is shaped by both Christianity and traditional Sami nature worship. The healing rituals may include prayer and the use of tools such as moss, water, stones, wool and soil. Examples of TM modalities offered is cupping, blood-stemming, laying on of hands, healing prayers, and rituals. The purpose of this study was to investigate the prevalence of the use of TM in areas with predominantly Sami and Norwegian populations, and the influence of ethnicity, geography, gender, age, education, household income, religiosity and self-reported health on such use.MethodsThe study is based on data collected in the first SAMINOR Survey (SAMINOR 1) conducted in 2003/2004, including three self-administered questionnaires, clinical measures, and blood analyses. Data was collected in 24 municipalities in Norway known to have a substantial population of Sami. All residents aged 30 and 36–78/79 years in the predefined regions were invited regardless of ethnic background (N = 27,987). Of these, 16,865 (60.3%) accepted to participate and gave their consent to medical research.ResultsOf the 16,544 people responding to the question about TM use, 2276 (13.8%) reported to have used TM once or more during their lifetime. The most outstanding characteristic of the TM users was the affiliation to the Laestadian church, where 34.3% (n = 273) reported such use, followed by an inner Finnmark residence (31.1%, n = 481) and a Sami ethnicity (25.7%, n = 1014). Women were slightly more likely to use TM compared to men (15.9% and 11.5% accordingly, p < 0.001), and the TM users were slightly younger than the non-TM users (mean age 52.3 versus 54.3 years, p < 0.001). The TM users also had lower income (p < 0.001) than the non-TM users. We found no significant differences between the TM users and the non-TM users concerning years of education, and whether the participants were living with a spouse/partner or not.ConclusionFurther studies are necessary to examine the development of TM use in Norway over time, and use in areas with mainly Norwegian inhabitants. There is also a lack of studies quantifying TM use among Sami people in Sweden, Finland and Russia.

BackgroundDepression has been identified as one of the most frequent predictors of CAM use. However, limited data exist about the use of CAM providers among people with anxiety/depression in Norway. The aim of this study was to investigate the use of CAM providers, and the use of CAM providers and psychiatric outpatient services in combination, among people with self-reported anxiety and/or depression.MethodsWe used questionnaire data from 12,982 participants (30–87 years) in the cross-sectional sixth Tromsø Study (conducted in 2007-8). Eligible for analyses in our study were 1685 participants who reported suffering from anxiety and/or depression. By descriptive statistical methods, we estimated the use of CAM providers, psychiatric outpatient services, and the combination of these. By logistic regressions we studied the association between the use of these services and gender, age, income, education, and self-reported degree of anxiety/depression.ResultsDuring the previous year, 17.8 % of people with anxiety/depression visited a CAM provider once or more, 11.8 % visited psychiatric outpatient services, and 2.5 % visited both. Men with anxiety/depression were less likely to visit CAM providers compared to women (odds ratio [OR] 0.40, confidence interval [CI] 0.30–0.55), whereas higher educated people were more likely to visit compared to the lowest educated (OR 1.47, CI 1.02–2.13). The use of CAM providers was not associated with the degree of anxiety/depression. For those who used both CAM providers and psychiatric specialist services during the previous year, severe anxiety/depression was strongly associated with use compared to moderate disease (OR 7.53, CI 2.75–20.65).ConclusionsPeople with severe anxiety/depression seem to use CAM providers and psychiatric services additionally, whereas those with moderate disease seem to use these services more as alternative pathways. CAM provider treatment might be a substitute for conventional care, particularly in patients with moderate disease.
