The mDIARY Study

Use of mHealth enhanced self-monitoring as an adjunct to the treatment of borderline personality disorder

mDiary is a project where patient self-reported data are collected through smartphones. Data is sent to a server and stored. Relevant visualisations, summed calculations and psychoeducation material can be re-accessed through patients’ smartphone, or the information can also be obtained in another tailored format for therapists through a web based interface. This info is used as an integrated part of the psychotherapy.

The mDiary study has more objectives

  • To investigate whether patients using the app will be faster in acquiring DBT skills to manage their emotions compared to patients using the pen and paper version.
  • To investigate whether patients using the app report fewer and less severe BPD-symptoms (e.g. less high-risk behavior, less self-harm, less negative affect, and ability to emotionally regulate) compared to patients using the pen and paper version.
  • To investigate whether changes in positive affect can predict improvements in DBT psychotherapy.
  • To evaluate whether the use of the app is cost-effective as compared to the pen and paper version. A separate HTA-study will draw data from public registries (landspatientregistret) to assess cost-effectiveness.

Selected quotes from a patient and therapist participating in the mDiary study

"The phone is so much easier to use than paper, most of us have it with us all the time, it is always there" - patient

"I feel more prepared when I have read the journal notes before I see the patient ... I know that if there are days where every registration is high, then that is a day we would most likely discuss" - therapist

The ENTER program consists of five research projects that aim to:

  1. Develop novel technologies and forms of service delivery improving treatment outcomes for patients within a mental health care setting.
  2. Provide evidence for the clinical and cost effective benefits and possible risks of using technologies in mental health care services.
  3. Enable ENTER´s industry partners to market their products nationally and internationally based on the proven feasibility of the technologies.
  4. Disseminate research results directed at the patient organisations and policy makers in mental health care, and representatives of multiple bodies of clinical practice – pending clinical efficacy, successful implementation in the care and management of patients with mental disorders and mental health problems.
  5. Establish a fruitful, collaborative research environment for e-mental health research with a national networking organization to persist beyond the present project.
