Those suffering from nagging tinnitus can benefit from internet-based therapy just as much as patients who take part in group therapy sessions. These are the findings of a German-Swedish study in which patients with moderate to severe tinnitus tried out various forms of therapy over a ten-week period.
The outcome of both the internet-based therapy and group therapy sessions was significantly better than that of a control group that only participated in an online discussion forum and thus demonstrated both the former to be effective methods of managing the symptoms of irritating ringing in the ears. The study was conducted by the Clinical Psychology and Psychotherapy division of the Institute of Psychology at Johannes Gutenberg University Mainz (JGU) and the Department of Behavioral Sciences and Learning at LinkÃ¶ping University in Sweden.
According to the German Tinnitus League (Deutsche Tinnitus-Liga, DTL), two percent of the population suffer from moderate to unbearable tinnitus. But the symptoms of tinnitus can be successfully managed by means of cognitive behavioral therapy. However, not everyone has the opportunity or the desire to take a course of psychotherapy. As shown by the German-Swedish study, those affected by tinnitus can now achieve the same level of outcome with the help of an internet-based therapy program, which encourages them to adopt individual and active strategies to combat their tinnitus. For the purposes of the study, the training program developed in Sweden was adapted so that it could be used for German patients and then be evaluated for its effectiveness.
The study showed that distress measured using the Tinnitus Handicap Inventory was reduced on average from moderate (40 points) to mild (29 points) in participants who completed the internet-based training course. The results for subjects in the cognitive behavioral therapy group were also very good, with distress levels being reduced from 44 to 29 points. In contrast, there was hardly any change in this respect in the control group subjects participating in the online discussion forum. Their average distress level was 40 points at the beginning of the study and remained at 37 points thereafter. "Our internet-based therapy concept was very effective when it came to the reduction of tinnitus-related distress or, to put it another way, at increasing the tolerance levels of subjects with regard to their tinnitus," concludes Dr. Maria KleinstÃ¤uber of the Clinical Psychology and Psychotherapy division at JGU.
At the same time, another interesting result was produced with regard to the preferred method of therapy. A significant number of subjects were initially skeptical with regard to the internet-based therapy concept and expressed a preference for the group therapy course. However, they were randomly assigned to the groups. To everyone's surprise it turned out on the completion of treatment that there was no difference in the effectiveness of the two strategies. "This means that the internet-based therapy concept produced as positive a result as group therapy despite the initial skepticism," says KleinstÃ¤uber. Initial evaluations indicate that the effects of both therapy forms were still persisting after six months.
The authors of the study propose that internet-based forms of therapy should be increasingly used in the psychotherapeutic treatment of tinnitus patients. Furthermore, they call for additional research on patients' skepticism of internet-based therapy, particularly in view of the long waiting times and the lack of outpatient forms of therapy.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
