About PsiTri

General

PsiTri is a freely available, clinical trial based database on treatments and interventions for a wide range of mental health related conditions, such as:

  • addictions, including drugs and alcohol
  • anxiety
  • autism
  • behavioural problems (attention-deficit hyperactivity disorder, conduct disorder)
  • bipolar disorder
  • cognitive enhancement
  • cognitive impairment
  • dementia
  • depression
  • delirium
  • eating disorders
  • obsessive-compulsive disorder
  • panic disorder
  • personality disorders
  • phobic disorders
  • psychosexual disorders
  • schizophrenia
  • sleep disorders
  • somatoform disorders

PsiTri offers access to the content of the specialised trial registers of the five mental health related Cochrane Collaborative Review Groups. The groups submit their updated registers to PsiTri monthly.

PsiTri contains information on randomised controlled trials (RCTs) or controlled clinical trials (CCTs) only.

Psitri is more than a traditional reference database. Whereas traditional databases contain reference information only, PsiTri also includes information on the trials behind these references. The trial data which is extracted from the references reporting on a specific trial, includes information on: health condition, interventions/treatment, participants, research methods, blinding, outcomes, i.e. how the effect of the interventions was measured etc.

For example:

  1. Buitelaar et al. have a research interest pindolol versus methylphenidate as a treatment for children with attention-deficit hyperactivity disorder, and thus initiate a trial, where the effect of these both interventions is compared and tested.
  2. When the trial is completed, or in a phase where some preliminary results of the effects of pindolol versus methylphenidate on children with attention-deficit hyperactivity disorder may be seen, Buitelaar et al. write two reports of the results of the trial, and both of them are published. These are the trial's references. The references report on different aspects of the trial (research methods, participants, outcomes etc). This information is extracted and made visible in PsiTri as well as general reference date (title, author, source etc).
