Introduction
I am interested in the efficacy of neuromodulation therapies in the treatment of tinnitus - or other brain-related conditions. Generally, I want to pursue treatments that can help ameliorate symptoms of chronic (brain-based) conditions.

Description
- PhD project examines the efficacy of a neurofeedback protocol on symptoms of tinnitus in a cohort of chronic tinnitus sufferers. Because I was the applicant and grantee for the funding, I have been heavily involved in- and instrumental for the development and execution of our randomized, controlled trial. Project completion is expected ultimo 2020.

Background: Tinnitus is a particularly common condition and can have debilitating psychological consequences for certain people. Although several interventions have been helpful in teaching individuals to better cope with tinnitus, no cure exists at present. Neurofeedback is an emerging treatment modality in tinnitus. Previous studies, utilising an...
Previous studies showed that alpha/delta ratio neurofeedback was effective in reducing unpleasant psychological, emotional, and perceptual consequences of tinnitus. The main goal of the present study was to investigate, whether the specific combination of enhancing alpha- and reducing delta frequency band activity was necessary, or merely sufficien...
Subjective, chronic tinnitus is a condition that is common in most populations. Whereas many individuals tend to habituate to tinnitus over time, for some their attention seems pathologically drawn towards the sensation. For this subgroup of individuals with severe tinnitus, dysfunctional executive attention has been suggested to be implicated in t...
Objectives
Chronic tinnitus negatively impacts daily functioning. To specifically assess this impairment, the Tinnitus Functional Index (TFI) was developed. The current study investigated the hierarchical, eight-factorial structure for the German TFI and examined its psychometric properties.
Design
In an online assessment, the TFI and other valida...

What is the general consensus on one vs. two-tailed hypothesis testing in planned contrasts? I have a repeated measures mixed design. The study consists of three groups (A, B, C) and we have three assessment comparisons, i.e. Time 1 vs Time 2, Time 1 vs. Time 3 and Time 1 vs. Time 4.
Group A is our intervention group
Group B is an active control group
Group C is a control group
Our hypotheses are directional:
Group A > Group B
Group A > Group C
Group B > Group C
In this case, would applying the one-tailed significance test be ok?

Can anyone here assist me with transforming a scale that goes from 0% - 100% to a 1 - 9 rating scale? I refer to a scale, the Credibility and Expectancy Scale (CEQ) which has four items rated from 1 - 9 and two items rated from 0 - 100%. Thank you.
Hi,
I have a question I hope you can help me with. I am not quite sure, which statistical test to use for sample size calculation for the following design:
2 (between groups) x (3 within conditions) x (4 within conditions) x (2 within conditions)
I am interested in main effects and interactions. Am I wrong to assume, that I am "underpowering" my study, if I select the test ANOVA: repeated measures, within-between interaction?
Repeated measures seem to me the wrong choice here, given that I do not repeat the same measure across time, i.e. Time1 and Time 2. I am testing differences in reaction time between two groups but across various trial conditions (i.e. some trials have cues preceeding the target, some cues are presented above and some below target etc...)
Any hints appreciated.
Regards,
Martin
I have two groups for whom I would like to compare their performance on a reaction time test. In group A, people with tinnitus, I have their audiometric data, i.e. level of hearing loss. I do not have this data for group B, individuals without tinnitus. Is there a work-around, where I can perform a statistics, in which I control for hearing loss in group A? Or do I have to collect the data for group B as well? Thanks in advance.
