cause and effect research method psychology

So whatever pain you are feeling is not mine. But again, even if we concede that lowering BMI is helpful, then what is wrong with the HAES approach? researcher cannot always guarantee that their particular manipulation of a variable was the sole reason for the perceived trends and correlation All of them? 6 Ways to Increase Happiness at Work and at Home. negative correlation: A relationship between two variables such that as one increases the other decreases. Very few things are proven as causing other things. I am advocating that the truth should be pursued and it is not being pursued in this realm. 2. I have a love/hate relationship with Yale's center. That is it. I resolved those issues personally years ago. In an experiment, the researcher manipulates the independent variable and watches for consequent changes in the dependent variable. I find the complexities of how the mind, the body and the social environment come together to create both health and illness fascinating and I hope future medical research will move in the direction of integration of these various systems to more holistically understand this wonderful thing called the human body. It also indicates that we should try extra hard to prevent obesity at younger ages," said Dr Peeters. it's just coincidence that every one of these studies found the association with obesity? This is not to underscore the effect that unhealthy behaviors and/or obesity may have on our health, simply to foster a sensitivity to the complex issues we face and ask people to apply some common sense when making sweeping generalizations and branding assumptions. And, btw, don't you think the cost of health care would be reduced significantly if every time an insured fat person went to the doctor their symptoms were ignore, they were given pills they don't need to lose weight and they are encouraged to have expensive surgeries that don't work or require multiple additional surgeries? I am advocating that in a culture that limits the life chances of fat people and treats them as less than human, approaches to health that emphasize weight loss are doomed to failure. In my case, that was certainly true: I got obese because I ate whatever I wanted without regard for the health, esteem and appearance consequences. Cause and effect refers to a relationship between two phenomena in which one phenomenon is the reason behind the other. Journal of the American Medical Association. Are you teaching a psychology class? Public Health ScienceDaily (Mar. 5. I have mixed feeling about this whole issue. One study is interesting, two studies, nice. Overall for men and women combined, for every five unit increase in BMI, the researchers observed a 31 percent increase in risk of death. BMIs are very problematic with a population that can grow 5 inches in 3 months. Then it is assumed that if the health of the lower weight persons is better than the higher weight persons (or some other combination of lower, middle and higher weights), the loss (or gain) of weight will bring all people into the same state of health. "Losing weight is healthy." How or why? The investigators observed similar patterns of risk even after accounting for differences in alcohol consumption, physical activity, and education level. It is up to anyone who reads an assertion of cause and effect to dissect it and come up with an alternative explanation. Indeed, as you may know, there is a national registry of people who have lost and kept off substantial amounts of fat. Medical mistakes are growing each year and by some estimates are in the neighborhood of the 3rd or 4th leading cause of death, even higher among adults under 40. As can be seen, establishing cause and effect is one of the most important factors in designing a robust research experiment. Weight gain seems to have stabilized in the United States in the past 10 years, so predicting that 25% of the population will be "obese" is not really founded: http://healthpolicyandreform.nejm.org/?p=13941. Missing research is just as important in understanding phenomena as critiquing existing research. This is panic rhetoric, not science. In the end, obesity itself is a complex issue and those with obesity often have to deal with a level of scrutiny that those of us who don't have weight problems escape...even if they partake in behaviors that are just as unhealthy. Which one of these studies took into account the stigmatization of fat persons, their dieting histories, their socioeconomic levels and other factors that might contribute and/or explain these correlations? But there is a problem with the general mainstream reporting of smoking research as well. I hear that loud and clear and I want to see everyone take that into account. Unfortunately this does not work well in complex situations. Ah! 2003;289(2):187-93. What concerns me most though is that you have stated that it isn't a civil rights issue because it is about behavior. A laboratory experiment is an experiment conducted under highly controlled conditions (not necessarily a laboratory), where accurate measurements are possible. If the results are better, it is easy to assume that the treatment caused the result, but this is not necessarily the case. ", Or worse yet, when we say, being fat doesn't hurt and are told "of course it does.". ScienceDaily (Oct. 11, 2010) — The cost of obesity among U.S. full-time employees is estimated to be $73.1 billion, according to a new study by a Duke University obesity researcher, published in the Journal of Occupational and Environmental Medicine. If you truly want to advocate for health and well-being, then how is HAES not doing that? "Mortality Rate - Obese Patients It also assumes that there is an obvious method of actually controlling weight. you claim these health effects came about due to "stigmatization"? Current guidelines from the U.S. Centers for Disease Control and Prevention, and the World Health Organization define a normal BMI range as 18.5 to 24.9. While correlational research is invaluable in identifying relationships among variables, a major limitation is the inability to establish causality. This is a population study. The temporal factor is usually the easiest aspect to neutralize, simply because most experiments involve administering a treatment and then observing the effects, giving a linear temporal relationship. The investigators observed similar patterns of risk even after accounting for differences in alcohol consumption, physical activity, and education level. You don't need our permission to copy the article; just include a link/reference back to this page. I said no one can claim they PROVED that cigarettes caused cancer, but the link between smoking and cancer and other diseases is a very strong case. I'm truly sorry you feel so much pain, and I am saddened that you believe that all people who advocate decreasing obesity "hate" you or other obese people. Causal or Experimental Research . An informed opinion is not problematic. While there is some truth behind this, you have to remember that most regular olive oil eaters also eat a Mediterranean diet, have active lifestyles, and generally less stress. Really? Even respected and trusted newspapers, journals and internet resources can fall into the causality trap, so marketing groups can influence perceptions. All you doi is take all the evidence of the harmful effects of obesity and find fault with them. Causes of death were obtained from death certificates or medical records. But I have the feeling that when fat people say "what you are doing is hurting me, it is not helping." These social effects are extremely difficult to minimize without creating other threats to internal validity. Fat people are human beings and those of us who have decided to make peace with our bodies and let our weight fall where it will naturally rather than fight to be something we are not should have a voice in the conversation. Did you even read my post? Barbarroja et al. I do not disagree with this result. It is a term you've likely heard many times already, or will hear many times as you study psychology. A study headed by Anna Dahl, MS, of Sweden's Jönköping University, found that individuals with higher midlife body mass index (BMI) scores had significantly lower general cognitive ability and significantly steeper decline than their thinner counterparts over time. Natural foods, no grains and little or no dairy has worked wonders for me, and even if I didn't lose another lb, I would continue to eat this way for health. Here's a good discussion of the problems with obesity research, including discussing the implications of the JAMA article: http://www.healthyweightnetwork.com/cntrovsy.htm#controvsy.htm, ================================================. Archaeology, economics and market research are other areas where cause and effect is important, so should provide some excellent examples of how to establish cause and effect. You give us a partial picture, and want to speak for all of mankind. Disaster Plan We just all sit around waiting for an excuse to do the worst things we can to our bodies? Staying Healthy http://jama.ama-assn.org/content/303/3/242.short (Note that the plateau occurred before Michelle Obama's current efforts.). Generally, this type of psychological research is used to show how psychology principles or theories are used in actual practice. This will skew the results and mask the effects of the entire experiment. I remember as a reporter keeping several calculations in a file to be used when discussing taxes or other such topics because it was important to report the numbers in a specific way that would tantalize rather than bore. Like some, but not all, people who do this, you lost weight. In a less culturally and emotionally charged context, these questions would be regarded as par for the course. The research team included investigators from the National Cancer Institute (NCI), part of the National Institutes of Health, and collaborators from a dozen other major research institutions worldwide. Science & Society The use of percentages instead of actual numbers of incidences can create the illusion of large numbers when they aren't there. So you want to speak, I get advocate a cost to that freedom? Also, nice summary of Muennig's work and other implications of the war on obesity in Engber's column on Slate: http://www.slate.com/id/2231508/pagenum/all/. But, from a societal perspective, it's also a choice that impacts health care costs for everyone else. It's bad feelings that lead to diabetes, heart disease, etc.? This means you're free to copy, share and adapt any parts (or all) of the text in the article, as long as you give appropriate credit and provide a link/reference to this page. I am a medical sociologist who is concerned with the social contexts to medical care. Most of the increased risk is due to cardiovascular causes. Social Issues Not at the point of diagnosis because symptoms usually are present before a diagnosis is sought. I decided I did not want to cause my own diabetes by continuing to eat whatever I wanted, notwithstanding the consequences. I wish you peace and self love, and I assure you that many people who advocate weight reduction do not "hate" obese people. As compared with a BMI of 22.5 to 24.9, the researchers report a 44 percent increase in risk of death for participants with a BMI of 30.0 to 34.9; an 88 percent increase in risk for those with a BMI of 35.0 to 39.9; and a 2.5 times (250 percent) higher risk of death for participants whose BMI was 40.0 to 49.9. And a lot of fun. I love medical sociology and I love thinking critically about how people speak about the world. No, really. BMI, the most commonly used measure for body fat, is calculated by dividing a person's weight in kilograms by the square of his/her height in meters (kg/m2). You are saying the shorter life expectancy and greater risk are from the weight and that, by implication, reduction of weight will increase health. Coronary heart disease Emotionally charged topics often miss these basics, but they are important nonetheless. Experiments is the only way to establish a cause and effect relationship because it is the only method that has an independent variable (IV) and a dependent variable (DV). http://timigustafson.com/2011/a-biological-basis-for-our-obesity-bias/, And for those who are challenging this post or what I believe to be the big message here which is challenging our assumptions about obesity, please read about HAES first. Time Lived With Obesity Linked With Mortality 3. Here eating without any physical activity is the “cause” and weight gain is the “effect.”. Multiple group threats are a danger to causality caused by differences between two or more groups of participants. Again, I think some people are missing the point. No one is saying obesity isn't (at least in some individuals) related to health problems...but there is a huge difference between saying that obesity increases the chance of developing diabetes in individuals who are already genetically predisposed and saying that obesity causes diabetes. But again, even if we concede that dieting and exercise might result in lower body rates, there is nothing in this study to demonstrate that lowering the BMI will result in better health. I'm a happy person and quite comfortable in my own skin. I know people who have gained. I'm not the best source of information on this, but I do know others who have looked into this and have pointed out that the incidences of Type-II diabetes among kids and adolescents are still in the 1 per 10,000 or so range, making it way less than 1% of the population. Science, good science, doesn't allow for dogma. The other problem with causality is that a researcher cannot always guarantee that their particular manipulation of a variable was the sole reason for the perceived trends and correlation. I know people who advocate HAES who lost weight when they began to emphasize health not weight in their own habits. Studies that look at an effect and seek the cause; ask many questions and then compare the answers through correlational analysis Tests Procedures used to measure attributes of individuals at a particular time and place; results can be used for correlational analysis or for generating ideas for other research What I say to my students who ask me how can anyone find the time to examine all the information coming at them and fully understanding it is: If you don't have the time to examine it, then don't repeat it. ScienceDaily (June 6, 2011) — Women with a healthy body weight before and after diagnosis of breast cancer are more likely to survive the disease long term, a new study finds. Many of the people who lose weight have complications from either the attempt to lose weight or from the weight loss itself, so asserting that it improves health is a mixed result, not a strong one. The reason that this prediction is not causation is because it doesn't meet criteria #3, which is there is an alternative explanation for the predictive relationship: the summer heat -- which leads people to open pools and leads people to eat more ice cream.
