Study Finds TV Portrayal Of Psychological Therapy Influences Willingness To Seek It
Network television programming might suggest that America is fascinated with the idea of psychological counseling.
Frasier Crane and his brother, Niles, both practiced psychiatry on their popular NBC sitcom “Frasier.” Mob boss Tony Soprano had his therapist on HBO’s hit show “The Sopranos.” And HBO has even made therapy the focus of two recent shows — “Tell Me You Love Me” and “In Treatment.”
But all of these TV portrayals may actually make viewers less likely to seek psychological services themselves. That’s according to a new study by three Iowa State University psychologists.
ISU psychology professors David Vogel and Douglas Gentile collaborated with graduate student Scott Kaplan on the study of 369 Iowa State students. It explored how exposure to television shows may contribute to negative perceptions about psychological services that can lead to lower intentions to seek such services. They produced a paper titled “The Influence of Television on Willingness to Seek Therapy,” which was published in the March issue of the Journal of Clinical Psychology, a professional journal.
Unflattering portrayals of mental health professionals
Kaplan has conducted a related content analysis on television portrayals of mental health professionals. It found that they’re not favorable.
“Generally, it seems like therapists are portrayed unethically — like sleeping with the client, or implanting false memories, or talking about their clients outside the session,” Vogel said. “These are things that almost never happen with real therapists, but on a show — because they’re probably more exciting — they happen more frequently.”
“Therapists also often are portrayed as buffoons,” Gentile said. “That’s either by being the jokester, like Frasier, or by being the butt of jokes. In either case, these are not positive portrayals. They do not show the skill, expertise and ethics of professional therapists.”
But it’s not just the portrayal of the therapists that may be keeping people out of therapy. It’s also the portrayal of those who seek counseling on TV.
“If you examine the portrayal of the clients, it’s probably as bad or worse,” Vogel said. “So why would you seek therapy if you believe you’re going to be perceived negatively and you’re going to see someone who’s incompetent and not able to help you?”
Because dramas and comedies are the two types of shows that often portray psychologists and psychotherapy, the ISU psychologists asked respondents how often they watched TV comedy and drama shows. They also asked them to assess perceptions of the stigma associated with seeking professional help, attitudes toward therapy, their intentions to seek therapy for psychological and interpersonal concerns, and their feelings of depression.
TV ties to therapy stigma
The study found a positive correlation between viewers’ exposure to comedy and drama shows and their perceptions of stigma associated with seeking professional help. This stigma was then related to lower willingness to seek professional mental health services.
“One of the things that’s important to note about this particular study is that we showed that TV exposure was related to your perceptions of the stigma associated with seeking help, which has been found to be one of the main factors found from inhibiting people from seeking that help,” Vogel said. “So you perceive that yourself, and other people, would be crazy to go (to therapy).”
That’s a problem for those people who could really benefit from professional mental health services. According to Vogel, the most recent studies in the mental health field have found that about half of population experiences a situation in their lives where psychological therapy could be helpful — about 20 percent in a single year. But in a given year, only about 10 percent of the people who could benefit from therapy will seek help from a psychologist or other mental health professional.
“Mental health services are already vastly underutilized, and this cultural stigma is part of the reason,” Gentile said. “And this study suggests that this cultural stigma exists partly because of the way that psychologists and their patients are portrayed on television.”

Obesity Can Increase Dementia Risk By Up To 80 Percent
Being obese can increase the risk of Alzheimer’s Disease by as much as 80 percent, according to a study in the May issue of Obesity Reviews.
But it’s not just weight gain that poses a risk. People who are underweight also have an elevated risk of dementia, unlike people who are normal weight or overweight.
US researchers carried out a detailed review of 10 international studies published since 1995, covering just over 37,000 people, including 2,534 with various forms of dementia. Subjects were aged between 40 and 80 years when the studies started, with follow-up periods ranging from three to 36 years.
The review, which included studies from the USA, France, Finland, Sweden and Japan, also included a sophisticated meta-analysis of seven of the studies, published between 2003 and 2007 with a follow-up period of at least five years.
All kinds of dementia were included, with specific reference to Alzheimer’s Disease and to vascular dementia — where areas of the brain stop functioning because the blood vessels that supply them are damaged by conditions such as high blood pressure or heart disease.
“Our meta-analysis showed that obesity increased the relative risk of dementia, for both sexes, by an average of 42 percent when compared with normal weight” says Dr Youfa Wang, Associate Professor of International Health and Epidemiology at Johns Hopkins Bloomberg School of Public Health, Baltimore.
“And being underweight increased the risk by 36 percent.
“But when we looked specifically at Alzheimer’s Disease, the increased risk posed by obesity was 80 percent. The increased risk for people with vascular dementia was 73 percent.
“The risks were greater in studies where sufferers developed Alzheimer’s Disease or vascular dementia before the age of 60 or in studies with follow-up periods of more than 10 years.
“We also found that obesity was more likely to be a risk factor for women when it came to developing Alzheimer’s Disease and for men when it came to vascular dementia.”
The authors estimate that 12 percent of the dementia risk in the study population could be attributed to obesity, with this rising to just over 21 percent in patients with Alzheimer’s Disease.
It’s estimated that up to 10 percent of people aged 65 or more suffer from some form of dementia and two-thirds of those have Alzheimer’s Disease.
“There has been controversy about the links between obesity and dementia for a number of years, but previous findings have been mixed and inconclusive” says Dr Wang.
“The advantage of carrying out a meta-analysis is that it provides researchers with access to a large number of study subjects and it is possible to iron out the inconsistencies and come to overarching conclusions.
“Our detailed analysis clearly shows a U-shaped relationship between weight and dementia, with people who are obese or underweight facing a greater risk.
“We believe that our results show that reducing the prevalence of obesity is a promising strategy for preventing the progression of normal ageing into Alzheimer’s Disease.”

Record-Setting Laser May Aid Searches For Earthlike Planets
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. The same NIST group also has shown that this type of laser, when used as a frequency comb — an ultraprecise technique for measuring different colors of light — could boost the sensitivity of astronomical tools searching for other Earthlike planets as much as 100 fold.
The dime-sized laser, to be described Thursday, May 8, at the Conference on Lasers and Electro-Optics, emits 10 billion pulses per second, each lasting about 40 femtoseconds (quadrillionths of a second), with an average power of 650 milliwatts. For comparison, the new laser produces pulses 10 times more often than a standard NIST frequency comb while producing much shorter pulses than other lasers operating at comparable speeds. The new laser is also 100 to 1000 times more powerful than typical high-speed lasers, producing clearer signals in experiments. The laser was built by Albrecht Bartels at the Center for Applied Photonics of the University of Konstanz.
Among its applications, the new laser can be used in searches for planets orbiting distant stars. Astronomers look for slight variations in the colors of starlight over time as clues to the presence of a planet orbiting the star. The variations are due to the small wobbles induced in the star’s motion as the orbiting planet tugs it back and forth, producing minute shifts in the apparent color (frequency) of the starlight. Currently, astronomers’ instruments are calibrated with frequency standards that are limited in spectral coverage and stability. Frequency combs could be more accurate calibration tools, helping to pinpoint even smaller variations in starlight caused by tiny Earthlike planets. Such small planets would cause color shifts equivalent to a star wobble of just a few centimeters per second. Current instruments can detect, at best, a wobble of about 1 meter per second.
Standard frequency combs have “teeth” that are too finely spaced for astronomical instruments to read. The faster laser is one approach to solving this problem. In a separate paper, the NIST group and astronomer Steve Osterman at the University of Colorado at Boulder describe how, by bouncing the light between sets of mirrors a particular distance apart, they can eliminate periodic blocks of teeth to create a gap-toothed comb. This leaves only every 10th or 20th tooth, making an ideal ruler for astronomy.
Both approaches have advantages for astronomical planet finding and related applications. The dime-sized laser is very simple in construction and produces powerful and extremely well-defined comb teeth. On the other hand, the filtering approach can cover a broader range of wavelengths. Four or five filtering cavities in parallel would provide a high-precision comb of about 25,000 evenly spaced teeth that spans the visible to near-infrared wavelengths (400 to 1100 nanometers), NIST physicist Scott Diddams says.
Osterman says he is pursuing the possibility of testing such a frequency comb at a ground-based telescope or launching a comb on a satellite or other space mission. Other possible applications of the new laser include remote sensing of gases for medical or atmospheric studies, and on-the-fly precision control of high-speed optical communications to provide greater versatility in data and time transmissions. The application of frequency combs to planet searches is of international interest and involves a number of major institutions such as the Max-Planck Institute for Quantum Optics and Harvard Smithsonian Center for Astrophysics.

Oxygen Depletion: A New Form Of Ocean Habitat Loss
An international team of physical oceanographers including a researcher from Scripps Institution of Oceanography at UC San Diego has discovered that oxygen-poor regions of tropical oceans are expanding as the oceans warm, limiting the areas in which predatory fishes and other marine organisms can live or enter in search of food.
The new study is led by Lothar Stramma from the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, and is co-authored by Janet Sprintall, a physical oceanographer at Scripps Oceanography and others. The researchers found through analysis of a database of ocean oxygen measurements that levels in tropical oceans at a depth of 300 to 700 meters (985 to 2,300 feet) have declined during the past 50 years. The ecological impacts of this increase could have substantial biological and economical consequences.
“We found the largest reduction in a depth of 300 to 700 meters (985 to 2,300 feet) in the tropical northeast Atlantic, whereas the changes in the eastern Indian Ocean were much less pronounced,” said Stramma. “Whether or not these observed changes in oxygen can be attributed to global warming alone is still unresolved. The reduction in oxygen may also be caused by natural processes on shorter time scales.”
Sprintall said the oxygen-poor areas have the potential to move into coastal areas via currents that flow from the mid-depth tropical oceans, where the oxygen changes were observed, and along the west coast of continents.
“The width of the low-oxygen zone is expanding deeper but also shoaling toward the ocean surface,” said Sprintall, a specialist in observing changes of fluxes in ocean properties such as heat distribution.
Sprintall contributed data to the study gathered during recent cruises undertaken as part of the Climate Variability and Predictability (CLIVAR) program, a long-running study operated by the World Climate Research Programme that seeks to understand climate through ocean-atmosphere interactions.
The study, “Expanding Oxygen-Minimum Zones in the Tropical Oceans,” appears in the May 2 edition of the journal Science. The research team includes Stramma, Sprintall, NOAA scientist Gregory Johnson, and Volker Mohrholz from the Institute for Baltic Sea Research in Warnem??nde, Germany.
The team selected ocean regions for which they could obtain the greatest amount of data to document the decline in oxygen. Some of the more recent data came from oxygen sensors which have been added to about 150 of the profiling floats used in Argo, a worldwide network of sensors that track basic ocean conditions such as temperature and salinity. There are more than 3,000 Argo floats operating in the world’s oceans, and Sprintall said the quality of the data gathered by the Argo floats suggests that more units in the network should be outfitted with oxygen sensors.
Lisa Levin, a biological oceanographer at Scripps Oceanography who studies oxygen-minimum zones that intercept the seafloor, said an expansion of oxygen-minimum zones in the oceans could lead to diminished biodiversity and to the expanded distributions of organisms that have adapted to live in hypoxic, or oxygen-poor waters.
“I think it’s uncharted territory,” said Levin, who was not affiliated with the study. “Thicker oxygen minimum zones could affect nutrient cycling, predator-prey relationships and plankton migrations. Where the expanding oxygen-minimum zones impinge on continental margins, we could see huge ecosystem changes.”
