Study summary

The goal of this observational study is to learn about the role of repetitive negative thinking (measured by the RTQ) in adult populations from an anxiety disorders and trauma clinic.

The main questions it aims to answer are:

  • Whether the repetitive negative thinking can be used to predict i. initial symptom severity, and ii. therapy outcome (measured by change in scores on disorder specific measures).
  • Whether change in RTQ mediates change in outcome Participants are sent weekly questionnaires that measure their progress. Within these questionnaires are the RTQ and other disorder-specific measures that we will be analysing.

Researchers may also compare clients with different disorders to see the accuracy the RTQ can predict treatment outcomes for each disorder.

Read the detailed description

We are looking to examine how repetitive negative thinking (RNT; i.e. rumination and worry), measured by the repetitive thinking questionnaire (RTQ), affects the outcomes of Cognitive Behavioural Therapy (CBT) for anxiety and trauma disorders. Our study will involve looking over data collected from clients who completed treatment at the Centre for Anxiety Disorders and Trauma (CADAT) from 01/01/2022 to 31/03/2024, we will look at data from before they started treatment, whilst in treatment and once they completed treatment. This is an important issue to address as there is little guidance within existing CBT protocols on to how to identify and target RNT during treatment. Evidence also suggests that not only does RNT maintain anxiety disorders, but it can also interfere with therapy outcome. Research has found that patients receiving CBT for PTSD who displayed high-levels of rumination within their early CBT sessions had poorer outcomes in therapy. Our aim is to formally analyse the relationship between scores on the RTQ and both symptom severity and CBT treatment outcome for anxiety disorders. This would help us to test our hypotheses about the relationship (i.e. those with high RNT have poorer treatment outcomes and changes in RNT predict outcome across a range of anxiety and trauma disorders) and provide a basis for augmenting our existing treatments with interventions that specifically target this process.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 17, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
