Breaking Down Barriers to a Suicide Prevention Helpline

Not Applicable

Completed

• Conditions: Suicidal Ideation

• Registration Number: NCT05458830
• Lead Sponsor: 113 Suicide Prevention

Brief Summary

Every month, around four thousand people fill in the anonymous self-test for suicidal thoughts on the website of the Dutch suicide prevention helpline 113 Suicide Prevention. The self-test includes the Suicidal Ideation Attributes Scale (SIDAS) and informs people about the severity of their suicidal thoughts. The vast majority (70%) of people who complete the test score higher than the cut-off point (≥ 21) for severe suicidal thoughts. Despite this, only around 10% of test-takers navigate to the webpage about contacting the helpline.

In this study the investigators test an intervention that aims to reduce barriers to contacting the helpline via chat or phone. People with severe suicidal thoughts and little motivation to contact the helpline will be randomly allocated either to a brief Barrier Reduction Intervention (BRI) or care as usual, a plain advisory text.

The aim of our study is two-fold: (i) to measure the effectiveness of a brief barrier reduction intervention (BRI) in the self-test motivating people with severe suicidal thoughts to contact the helpline, and (ii) to specifically evaluate the effectiveness of the intervention in increasing service utilisation by high-risk groups for suicide such as men and people of middle age.

Detailed Description

Research suggests that people with suicidal thoughts often do not seek help, making them invisible for preventive measures and targeted support. Anonymous online help can be a low-threshold first step towards professional face-to-face help. In the Netherlands, the suicide prevention organisation '113 Suicide Prevention' provides around-the-clock anonymous support by phone and chat, as well as an online self-help course, self-assessment tests and brief online coaching and therapy. Apart from the homepage, the 'test yourself' page is the most visited section of the helpline's website. Every month, more than 4,000 people fill in the anonymous self-test for suicidal thoughts. This self-test includes the Suicidal Ideation Attributes Scale (SIDAS) and informs the test-taker of the severity of their suicidal thoughts. Although the vast majority of people who complete the test score higher than the cut-off point for severe suicidal thoughts, only approximately 10% of test-takers go on to navigate to the web-page about contacting the helpline. And although due to the anonymity of the helpline's services it is not possible to know if people follow up the advice of contacting the helpline, the difference in demographic distributions between the users of the self-test and the crisis helpline confirms the assumption that a substantial group does not continue using helpline service. While the percentage of men among the self-test users is 40%, it is only around 25% among the users of the helpline.

The study is designed as a randomised controlled trial for the anonymous users of an online self-test for suicidal thoughts in which individuals with severe suicidal thoughts and no interest in contacting the helpline will be randomly allocated either to a short barrier reduction intervention (BRI) or receive a general advisory text (care as usual). To minimise the burden on our high-risk and sensitive study population, the investigators aim that it is feasible for the participants to complete the intervention within 10 minutes.

The aim of our study is two-fold: (i) to measure the effectiveness of a brief barrier reduction intervention (BRI) in the self-test motivating people with severe suicidal thoughts to contact the helpline, and (ii) to specifically evaluate the effectiveness of the intervention in increasing service utilisation by high-risk groups for suicide such as men and people of middle age.

Primary Outcome Measures

Name	Time	Method
The use of a direct link to the helpline	immediately after intervention	The primary outcome measure is the use of a direct link to the helpline after completing the intervention or the control condition (plain advisory text, care as usual).

Secondary Outcome Measures

Name	Time	Method
Self-reported likelihood of contacting the helpline	immediately after intervention	Due to the anonymous nature of the helpline, it is not possible to measure if people who do not directly use the link to the helpline, contact the helpline at a later point in time. Therefore, the self-reported likelihood of contacting the helpline (5-point interval scale, ranging from not likely to very likely) is included as a proxy measurement.
