(Medical Xpress) -- Online depression therapy programs can have a positive impact on more than just depressive symptoms, a new study from The Australian National University reveals.
Dr. Lou Farrer, from the ANU Centre for Mental Health Research, part of the ANU College of Medicine, Biology and Environment, trialled the effectiveness of online programs MoodGYM and BluePages with users of Lifeline’s telephone crisis line. She found that the online programs had a positive influence across a range of problems – not just depression.
“In addition to reducing depression symptoms, we found that the online programs were effective in reducing hazardous alcohol use in Lifeline callers. There was a significant drop in alcohol use among those who used MoodGYM and BluePages,” she said.

“The results also showed that people who used the online programs had a marked increase in their quality of life, as measured by a scale that assessed satisfaction with different areas of daily living.
“We also found that after treatment, people’s knowledge of depression increased. This is essential to enable people to be able to better understand and recognize the signs and symptoms of future depressive episodes.”
Dr. Farrer said that these results follow on from her original study published in 2011, which showed that the use of online programs for Lifeline callers was effective in reducing symptoms of depression.
“We worked with Lifeline centres in Melbourne, Sydney, Brisbane and the Sunshine Coast. Lifeline telephone crisis supporters identified callers who seemed to be experiencing symptoms of depression or anxiety. These people were then split into different groups who were asked to complete different programs using the online intervention tools MoodGYM and Blue Pages.”
Dr. Farrer said that these results showed that depression treatments can have important flow on effects.
“We didn’t expect these results, as the programs are designed specifically to treat depression.  It’s exciting to see that by alleviating depression, these programs may also be helpful in improving how people function in their day-to-day lives,” she said.
“What we need now is funding to roll these programs out into Lifeline on a more permanent basis so that callers can benefit.”

'Self-distancing' can help people calm aggressive reactions, study finds



A new study reveals a simple strategy that people can use to minimize how angry and aggressive they get when they are provoked by others.
When someone makes you angry, try to pretend you're viewing the scene at a distance - in other words, you are an observer rather than a participant in this stressful situation. Then, from that distanced perspective, try to understand your feelings.
Researchers call this strategy "self-distancing."
In one study, college students who believed a lab partner was berating them for not following directions responded less aggressively and showed less anger when they were told to take analyze their feelings from a self-distanced perspective.
"The secret is to not get immersed in your own anger and, instead, have a more detached view," said Dominik Mischkowski, lead author of the research and a graduate student in psychology at Ohio State University.
"You have to see yourself in this stressful situation as a fly on the wall would see it."
While other studies have examined the value of self-distancing for calming angry feelings, this is the first to show that it can work in the heat of the moment, when people are most likely to act aggressively, Mischkowski said.
The worst thing to do in an anger-inducing situation is what people normally do: try to focus on their hurt and angry feelings to understand them, said Brad Bushman, a co-author of the study and professor of communication and psychology at Ohio State.
"If you focus too much on how you're feeling, it usually backfires," Bushman said.
"It keeps the aggressive thoughts and feelings active in your mind, which makes it more likely that you'll act aggressively."
Mischkowski and Bushman conducted the study with Ethan Kross of the University of Michigan. Their findings appear online in the Journal of Experimental Social Psychology and will be published in a future print edition.
There were two related studies. The first involved 94 college students who were told they were participating in a study about the effects of music on problem solving, creativity and emotions.
The students listened to an intense piece of classical music while attempting to solve 14 difficult anagrams (rearranging a group of letters to form a word such as "pandemonium"). They had only seven seconds to solve each anagram, record their answer and communicate it to the experimenter over an intercom.
But the plan of the study was to provoke the students into anger, which the experimenters did using a technique which has been used many times in similar studies.
The experimenter interrupted the study participants several times to ask them to speak louder into the intercom, finally saying "Look, this is the third time I have to say this! Can't you follow directions? Speak louder!"
After this part of the experiment, the participants were told they would be participating in a task examining the effects of music on creativity and feelings.
The students were told to go back to the anagram task and "see the scene in your mind's eye." They were put into three groups, each of which were asked to view the scene in different ways.
Some students were told to adopt a self-immersed perspective ("see the situation unfold through your eyes as if it were happening to you all over again") and then analyze their feelings surrounding the event. Others were told to use the self-distancing perspective ("move away from the situation to a point where you can now watch the event unfold from a distance…watch the situation unfold as if it were happening to the distant you all over again") and then analyze their feelings. The third control group was not told how to view the scene or analyze their feelings.
Each group was told the replay the scene in their minds for 45 seconds.
The researchers then tested the participants for aggressive thoughts and angry feelings.
Results showed that students who used the self-distancing perspective had fewer aggressive thoughts and felt less angry than both those who used the self-immersed approach and those in the control group.
"The self-distancing approach helped people regulate their angry feelings and also reduced their aggressive thoughts," Mischkowski said.
In a second study, the researchers went further and showed that self-distancing can actually make people less aggressive when they've been provoked.
In this study, 95 college students were told they were going to do an anagram task, similar to the one in the previous experiment. But in this case, they were told they were going to be working with an unseen student partner, rather than one of researchers (in reality, it actually was one of the researchers). In this case, the supposed partner was the one who delivered the scathing comments about following directions.
As in the first study, the participants were then randomly assigned to analyze their feelings surrounding the task from a self-immersed or a self-distanced perspective. Participants assigned to a third control group did not receive any instructions regarding how to view the scene or focus on their feelings.
Next, the participants were told they would be competing against the same partner who had provoked them earlier in a reaction-time task. The winner of the task would get the opportunity to blast the loser with noise through headphones - and the winner chose the intensity and length of the noise blast.
The findings showed that participants who used the self-distancing perspective to think about their partners' provocations showed lower levels of aggression than those in the other two groups. In other words, their noise blasts against their partner tended to be shorter and less intense.
"These participants were tested very shortly after they had been provoked by their partner," Mischkowski said.
"The fact that those who used self-distancing showed lower levels of aggression shows that this technique can work in the heat of the moment, when the anger is still fresh."
Mischkowski said it is also significant that those who used the self-distancing approach showed less aggression than those in the control group, who were not told how to view the anger-inducing incident with their partner.
This suggests people may naturally use a self-immersing perspective when confronted with a provocation - a perspective that is not likely to reduce anger.
"Many people seem to believe that immersing themselves in their anger has a cathartic effect, but it doesn't. It backfires and makes people more aggressive," Bushman said.
Another technique people are sometimes told to use when angered is to distract themselves - think of something calming to take their mind off their anger.
Mischkowski said this may be effective in the short-term, but the anger will return when the distraction is not there.
"But self-distancing really works, even right after a provocation - it is a powerful intervention tool that anyone can use when they're angry."

'Trophy Molecule' Breakthrough May Result in Cleaner, Cooler Nuclear Energy


                    Science Daily  — Experts at The University of Nottingham are the first to create a stable version of a 'trophy molecule' that has eluded scientists for decades.


In research published in the journal Science, the team of chemists at Nottingham has shown that they can prepare a terminal uranium nitride compound that is stable at room temperature and stored in jars in crystallized or powder form.
Previous attempts to prepare uranium-nitrogen triple bonds have required temperatures as low as 5 Kelvin (-268 °C) -- roughly the equivalent temperature of interstellar space -- and have therefore been difficult to work with and manipulate, requiring specialist equipment and techniques.
The breakthrough could have future implications for the nuclear energy industry. Uranium nitride materials may potentially offer a viable alternative to the current mixed oxide nuclear fuels used in reactors since nitrides exhibit superior high densities, melting points, and thermal conductivities. The process the scientists used to make the compound could offer a cleaner, lower-temperature route than current methods.
The research was led by Dr Stephen Liddle in the School of Chemistry, and much of the practical work was completed by PhD student David King. The work was also supported by colleagues at the University of Manchester.
Uranium nitrides are usually prepared by mixing dinitrogen or ammonia with uranium under high temperatures and pressures. Unfortunately, however, the harsh reaction conditions used in the preparation introduce impurities that are difficult to remove. In recent years, scientists have, therefore, focused their attention on using low-temperature molecular methods, but all previous attempts resulted in bridging rather than the target terminal nitrides.
The Nottingham team's method involved using a very 'bulky' nitrogen ligand (an organic molecule bonded to a metal) to wrap around the uranium centre and to create a protective pocket in which the nitride nitrogen can sit. The nitride was stabilised during the synthesis by the presence of a weakly bound sodium cation (positively charged ion) which blocked the nitride from reacting with any other elements. In the final stage, the sodium was gently teased away, removing it from the structure and leaving the final, stable uranium nitride triple bond.
Dr Liddle said: "The beauty of this work is its simplicity -- by encapsulating the uranium nitride with a very bulky supporting ligand, stabilising the nitride during synthesis with sodium, and then sequestering the sodium under mild conditions, we were able to at long last isolate the terminal uranium nitride linkage."
He added: "A major motivation for doing this work was to help us to understand the nature and extent of the covalency in the chemical bonding of uranium. This is fundamentally interesting and important because it could help in work to extract and separate the 2 to 3 per cent of the highly radioactive material in nuclear waste."
The research was supported by the UK National Electron Paramagnetic Resonance (EPR) Facility, which is funded by the Engineering and Physical Sciences Research Council and based in the Photon Science Institute at the University of Manchester. The uranium nitride contains an unpaired electron, and using EPR spectroscopy, it was found that it behaves differently from similar compounds prepared at Nottingham.
Professor Eric McInnes, from The University of Manchester, said: "EPR spectroscopy can give detailed information about the local environment of unpaired electrons, and this can be used to understand the electronic structure of the uranium ion in this new nitride. It turns out that the new nitride behaves differently from some otherwise analogous materials, and this might have important implications in actinide chemistry which is of vital technological and environmental importance in the nuclear fuel cycle."
The research has been funded and supported by the Royal Society, European Research Council, the EPSRC, and the UK National Nuclear Laboratory.
