The appeal of medical quackery: a rhetorical analysis.

Medical quackery has been a pressing issue nearly from the start of the medical profession - whether the nostrums and patent medications of old or the super-foods and miracle supplements of today. Throughout history and into the modern day, the medical establishment has tried to counteract the claims of charlatans in order to protect patients from potentially harmful treatments. Countering today's pseudo-medicine begins with an examination of what makes patients susceptible to the claims of quack medicine. Understanding why patients are susceptible to dubious health claims begins with an examination of the rhetoric used to persuade a demographic toward alternative therapies. This knowledge can then be used to educate patients, and to better demonstrate the benefits of evidence-based medicine while improving patient interactions.

Inoculation message treatments for curbing noncommunicable disease development.

OBJECTIVE: To study the effect of various types of inoculation message treatments on resistance to persuasive and potentially deceptive health- and nutrition-related (HNR) content claims of commercial food advertisers. METHODS: A three-phase experiment was conducted among 145 students from a Midwestern U.S. university. Quantitative statistical analyses were used to interpret the results. RESULTS: RESULTS provide clear evidence that integrating regulatory focus/fit considerations enhances the treatment effectiveness of inoculation messages. Inoculation messages that employed a preventative, outcome focus with concrete language were most effective at countering HNR advertising claims. The findings indicate that inoculation fosters resistance equally across the most common types of commercially advertised HNR product claims (e.g., absolute, general, and structure/function claims). CONCLUSIONS: As the drive to refine the inoculation process model continues, further testing and application of this strategy in a public health context is needed to counter ongoing efforts by commercial food advertisers to avoid government regulations against deceptive practices such as dubious health/nutrition claims. This research advances inoculation theory by providing evidence that 1) good regulatory fit strengthens the effect of refutational preemption and 2) an inoculation approach is highly effective at fostering resistance to commercial advertisers' HNR content claims. This macro approach appears far superior to education or information-based promotional health campaigns targeted solely at specific populations demonstrating rising rates of noncommunicable disease.

OBJETIVO: Estudiar el efecto de diversos tipos de tratamientos basados en mensajes de inoculación sobre la resistencia a los reclamos de los anunciantes de alimentos comerciales con contenidos persuasivos y potencialmente engañosos relacionados con la salud y la nutrición (RSN). MÉTODOS: Se llevó a cabo un experimento en tres fases en el que participaron 145 estudiantes de una universidad del centro oeste de los Estados Unidos. Para interpretar los resultados, se utilizaron análisis estadísticos cuantitativos. RESULTADOS: Se obtuvieron datos probatorios claros de que la integración de las consideraciones de la teoría del enfoque/ajuste regulador mejoran la eficacia de los tratamientos basados en mensajes de inoculación. Los mensajes de inoculación que adoptaron un enfoque de prevención de resultados y utilizaron un lenguaje concreto fueron más eficaces en contrarrestar los reclamos publicitarios RSN. Se observó que la inoculación fomenta la resistencia por igual frente a los tipos más frecuentes de reclamos RSN de los productos anunciados comercialmente (reclamos absolutos, generales, y de estructura y función). CONCLUSIONES: Mientras se mantienen los intentos de perfeccionar el modelo del proceso de inoculación, es preciso seguir poniendo a prueba y aplicando esta estrategia en un contexto de salud pública con objeto de contrarrestar las iniciativas regulares de los anunciantes de alimentos comerciales para evitar las reglamentaciones gubernamentales contra prácticas engañosas tales como los reclamos equívocos en materia de salud y nutrición. Esta investigación promueve la teoría de la inoculación al proporcionar datos probatorios de que 1) un buen ajuste regulador fortalece el efecto de la prevención refutadora; y 2) un método de inoculación resulta ser muy eficaz en fomentar la resistencia a los reclamos con contenidos RSN de los anunciantes comerciales. Este enfoque macro se muestra muy superior a las campañas de promoción de la salud educativas o basadas en la información dirigidas exclusivamente a poblaciones específicas que presentan tasas ascendentes de enfermedades no transmisibles.

Cancer quackery: the persistent popularity of useless, irrational 'alternative' treatments.

At a time when many readily believe that vaccines cause autism, or that government scientists created AIDS as a weapon of black genocide, it is not surprising that medical quackery, especially cancer quackery, remains a flourishing and lucrative business throughout the developed world. This review provides a brief recap of its history and an overview of the various types of unproven or disproved cancer therapies popular now in the United States and elsewhere.

Cancer, quackery and the vernacular meanings of hope in 1950s America.

Hope was central to cancer control in twentieth-century America. Physicians placed great store in its power to persuade people to seek medical help as early as possible in the development of the disease, when it was most amenable to treatment; to maintain patients' loyalty through what could be a long, painful and uncertain course of therapy; and to encourage doubts about alternative healers. Some also argued that hope could have beneficial therapeutic and psychological effects for patients. However, we know very little about its meanings for the public. Focusing on a large collection of letters written to the Food and Drug Administration in the 1950s concerning an anti-quackery campaign, this article explores how men and women responded to the competing messages of hope promoted by orthodox cancer organizations and by alternative healers. It asks: What did hope mean to such men and women? How did they construct this meaning? How did they decide which treatments were hopeful and which were not? And, how did they use hope to imagine the social world of cancer? In short, this article explores the vernacular meanings, epistemologies, and imaginative uses of hope among Americans in the mid-twentieth century.

Perceptions and use of dental quacks (unqualified dental practitioners) and self rated oral health in Trinidad.

OBJECTIVE: To investigate reasons for use of dental quacks, treatment received, satisfaction with treatment, perceived differences to qualified dentists, and relationships to sociodemographic factors and self rated oral health. METHOD: A 14-item questionnaire including closed and open questions, was administered by interview to adult patients attending government health centres in Trinidad. RESULTS: Data were collected between November 2001 and March 2002. Two hundred and two people from 273 invited to participate, were interviewed (response rate 74%). Sixty seven per cent reported visiting a dental quack. People who had used a quack were older, from lower socioeconomic groups and more likely to be living in an area where there were fewer government dental clinics. The most common reason for visiting a quack was toothache (74%) and extraction was the most common treatment received (61%). Forty three per cent of respondents were dissatisfied with the treatment received from a quack and 83% felt that treatment provided by a qualified dentist was different. Main reasons for using a quack were cost (53%) and availability (20%). People who had used a quack were less likely to rate their oral health as 'Very good' or 'Excellent'. CONCLUSION: Those using the services of dental quacks in Trinidad were more likely to have lower, self rated oral health. Affordability and availability of dental treatment were identified as barriers to care from qualified dentists.

Alternative therapies, 1990. An overview.

The availability of alternative therapies for many health problems is a well-documented historical fact. Alternative therapies are generally understood to be those therapies outside of the usually accepted medical therapies for disease processes, such as cancer, arthritis, diabetes, psoriasis, lupus, and AIDS. Some other descriptive terms utilized include questionable, unproven, dubious, unorthodox, and unconventional. These alternative therapies vary from active involvement in promotion of one's own health (exercise, diet) to quackery. In today's society, with emphasis on self-involvement with individual health, metabolic therapies have become the most widely practiced alternative therapy. In an antiestablishment, anti-intellectual climate, with an increasingly mobile, rootless population, alternative therapies are in somewhat of a renaissance. Some confusion exists regarding clinical trials and alternative therapies in the general population and in the noninvolved health profession. Various studies indicate that from 10% to 50% of cancer patients use some alternative therapy, with national expenditures ranging as high as $10 billion annually. Better-educated patients with higher-than-average income are more likely to choose alternative therapies and are frequently supported by a physician in this choice. Most cancer patients continue under a physician's care and continue usual therapy while pursuing alternative methods. Approximately 5% of cancer patients abandon appropriate therapy and pursue potentially harmful alternative methods. A variety of sociomedical questions are brought forth by studies of the use of alternative therapies. A great need for public and professional education regarding this subject is evident.
