Frequency of suicidal intrusions: Clinical Interview for Suicidal Intrusions [CISI], Suicidal Intrusions Attributes Scale [SINAS]
Achtergrond van het onderzoek
Suicide is a major public health problem, and it remains unclear which processes link suicidal plans to the act of suicide. Growing evidence shows that the majority of suicidal patients diagnosed with major depression or bipolar disorder report repetitive suicide-related images and thoughts. According to cognitive psychology research, suicide-related images predict suicidality, and repetitive suicide-related images or flash-forwards are therefore an essential target for suicide prevention. There is extensive research evidence from experimental and clinical studies that vividness of negative as well as positive intrusive images may be reduced by Dual Task (e.g. eye movements) interventions taxing the working memory. We propose that the eye movements during image retrieval will also reduce intensity and frequency of suicidal imagery and may be crucial in preventing the transition from suicidal imagery to actual suicidal behaviour.
The primary objective of SIMAGERY is to assess the prevalence of intrusive suicidal imagery and thoughts, and to evaluate the effectiveness of an Eye Movement Dual Task (EMDT) add-on treatment targeting suicidal imagery in depressed patients.
Study participants include depressed adults (18 years and older) with suicidal ideation (>1 SIDAS) and suicidal intrusions. Participants in the intervention group will receive a maximum of six EMDT-sessions and care-as-usual (CAU). Participants in the comparison group will only receive CAU.
The main study parameter is the frequency and intrusiveness of suicidal imagery. Furthermore, the vividness, emotionality, and quality of the suicidal intrusions are evaluated (Intrusion Interview); Secondary parameters include: suicidal behavior and suicidal ideation (SIDAS, BSSI), severity of depression (BDI-II), Brief Symptom Inventory (BSI), rumination (RRS) and hopelessness (BHS).
Doel van het onderzoek
We hypothesize that a dual task (eye movements) during suicidal imagery retrieval will reduce the frequency of such imagery.

Onderzoeksproduct en/of interventie
There are two arms in this study:
1. comparison group: care as usual (CAU) only
2. intervention group: CAU with EMDT add-on treatment
Care as usual (CAU)
Care-as-Usual for depression within the participating mental health care institutions typically consists of (evidence-based) psychotherapy and/or antidepressant treatment. We will ensure that all patients will receive and continue CAU during the course of the study. After each assessment, the CAU mental health care provider will be updated on the patient (with consent of the patient).
EMDT add-on treatment
The treatment will be an add-on module that addresses intrusive suicidal images and can be added to regular treatment. It will consist of max. six sessions each of approximately 1 hour, delivered at the participants’ mental health care center. Trained and supervised intervention psychologists from each participating center will carry out the EMDT sessions.
Each session will consist of the following steps:
1. Selection of intrusive suicidal flash-forward target images with related ideation.
2. Consecutive set of eye movements of 30 seconds by 10 second breaks. Between the sets, subjective units of distress scale (SUDS, scale 0-10) are administered to assess level of distress during imagery.
3. If the image still produces stress, the dual task procedure will be repeated for the target.
4. This procedure is repeated for all target images until all SUDS are at approximately 0, or the EMDT session is coming to an end.
