Internet-delivered Psychological Interventions for Tinnitus

Tinnitus can be very distressing for some individuals who experience it. The most studied intervention that works well for tinnitus distress is cognitive behavioral therapy (CBT). There is enough evidence to claim that internet-delivered guided CBT for tinnitus is as effective as CBT delivered face-to-face. The goal of this randomized controlled trial is to test the effectiveness of an internet-delivered cognitive behavioral therapy (CBT) for tinnitus and an internet-delivered mindfulness-based tinnitus stress reduction intervention by comparing them one against each other and a waiting list control group in the adult population experiencing tinnitus. The main questions this study aims to answer are: * Feasibility of delivering interventions for tinnitus distress over the internet. * Is any of the two interventions more effective in reducing tinnitus-related stress than the waiting list control? * Is the effectiveness of mindfulness intervention non-inferior to CBT intervention for tinnitus? * Is participant engagement and dropout different in mindfulness and CBT interventions? Participants will be randomly assigned to a CBT, Mindfulness, or control group and will be asked to engage with the materials prescribed to that group for eight weeks.
