Lay people intervening and preventing suicide in a public place: how is it done and is it effective?


Every year there are around 6,000 suicides in the UK (Samaritans, 2019). A third of them happen in a public place (Owens et al., 2009), i.e. any location outside of the home or any other private location.

The government has published policies aiming to educate local authorities about what to do in situations when an incident is about to occur in a public place (Cox et al., 2013; DoH, 2012; Pirkins et al., 2015). However, most public life-saving interventions are given by members of the public (Department of Health, 2012). Life-saving interventions refer to those situations in which a person would have died if it was not for the received intervention, regardless of the type of intervention (e.g. talking, restraining, calling for help).

And yet, bystander interventions (‘lay people’ intervening to prevent or stop a suicide attempt) remain an under-researched area of life-saving interventions. Thus, Owens and colleagues (2019) conducted the first UK-based qualitative research on life-saving interventions by lay people. They aimed to understand interventions given by bystanders and how strangers intervene in public places when someone is feeling suicidal.

Although most bystander interventions for suicide prevention in public places are given by members of the public, this area of interest remains under-researched.

Although most bystander interventions for suicide prevention in public places are given by members of the public, this subject remains under-researched.


In-depth qualitative interviews were conducted with a total of 33 adults of ages ranging from 19 to 64 years old (21 women and 12 men). They belonged to one of two groups:

  • People with lived experience of a suicide attempt in a public place, who were stopped by a stranger (N=12). The majority were women. Three were stopped on three occasions and one was stopped twice.
  • Interveners (N=21), who stopped a stranger’s suicide attempt in a public place. The majority were members of the public (N=13) and railway workers (N=6) or highway officers (N=2). The majority were also women. Most staff members and three members of the public stopped more than one attempt.

The interviews included a mix of free narrative (e.g. tell me as much as you remember about the event) and open-ended questions and questions to clarify what happened during the incident. The data were analysed using inductive thematic analysis. People with lived experience were asked how they felt about the received intervention and how that intervention took place, while the interveners described their course of actions and their decision-making processes before intervening.


Three key themes emerged as consecutive components of an intervention:

  1. recognition of the need to intervene,
  2. the intervention acts per se,
  3. and the aftermath.


The main indicators for the interveners of something not being quite right were the person at risk’s positioning in imminently dangerous places, as well as their “strange” locations. Importantly, the interveners also observed that the person at risk had no overt emotional distress, but, instead, they had “a blank and distant look”, and were described as “being in a bubble”. This was confirmed by the survivors, who recalled entering a trance-like state, feeling invisible and not paying attention to the outside world. Interestingly, contrary to popular belief, the person at risk’s appearance was not an indicator of immediate risk.

The intervention acts

The intervention per se can be understood as a continuum of complex and interconnected acts, ranging from gentle approaches (e.g. appeals to self-rescue, asking for permission to speak) to forcible and authoritative ones (e.g. physical restraint, commanding language). Decisions on which way to intervene were taken based on combinations of various factors, such as perceived immediacy of danger, the intervener’s sense of control and responsibility over the situation, perceived clarity of signs of suicidal intent, and the intervener’s personality and ability to interact verbally and non-verbally (e.g. use of silence).

The intervention lasted until emergency services took over, or until the person was no longer judged as being at risk. Broadly, the intervention can be described as three acts, which more often than not had to be multitasked by the intervener:

1. Connecting with the person at risk of suicide (‘bursting the bubble’)

  • Approach and make your presence known
  • Exchange names
  • Ask simple, factual questions and keep the conversation light, e.g. job, studying, living situation, weather etc.
  • Ask if you can call someone for them, e.g. friends, family
  • Talk lightly about yourself, but do not take the attention away from the person and do not pretend you know what they are going through
  • It was generally better not to enquire about their suicidal ideation or give them reasons to live
  • Sometimes it is enough to listen, be silent and be present even when the person seems not to respond to the intervention
  • Keep an open body language, and speak in a calm, sincere manner, always showing authenticity and care

2. Moving them to a safer location

  • Forcible restraint: vital in cases where the risk of death was judged as imminent but was not often well received by survivor or/and can injure the intervener themselves
  • Direct appeal, e.g. “Please/Would you step away from [..]” – mostly used when risk was judged as not imminent and the person at risk was judged capable of responding to the plea
  • Indirect appeal, e.g. “Would you like to go for a coffee [..]” – considered as the most positive and anchoring approach as it shows both kindness and validation.

3. Calling for help

  • Family/friends of the person at risk
  • Other bystanders: rarely successful, as people pretended not to notice the situation or refused to intervene out of fear of making things worse or a lack of confidence in their abilities to support
  • Emergency services: most interventions ended in the arrival of professional staff. Members of the public who intervened disclosed that they found it difficult and stigmatising to call for professional help once they had engaged with the suicidal person. Some did not know which services to call. All trained staff who intervened summoned for help prior to approaching the person, and limited their intervention to keeping them safe until help arrived.

End of intervention and aftermath

Interveners felt a mixture of emotions. When “handing over” the person to family/friends or emergency services they felt both relieved and excluded from the situation. Most felt unsupported after the intensely emotional and disturbing intervention, as well as sometimes unable to carry on with their day as if nothing happened. If the intervener did not have emergency services around, they felt an intense need to extricate themselves from the situation, especially in long interventions, but also feared what would happen to the person afterwards.

Key themes emerged as consecutive components of an intervention: recognition of the need to intervene, the intervention acts (‘bursting the bubble’, place of safety and call for help), and end of intervention (‘the aftermath’).

Suicide bystander interventions involve recognising the need to intervene, ‘bursting the bubble’, helping the person to a place of safety and calling for further help, and ‘the aftermath’ of the intervention.


  • Judgements of who is at risk of suicide in a public space depend on various factors relating to the person at risk, including their positioning, location, behaviour and, importantly, withdrawn demeanour (“being in a bubble”).
  • Interventions are complex and often involve multitasking. They consist of several acts and cannot be understood as stand-alone behaviours.
  • The type of intervention depends on location, the person at risk, and other intervener-intrinsic factors (e.g. level of immediate risk, personality, ability to communicate etc).
  • There is no ‘one size fits all’. Often, lay people lack information about the most effective way to intervene and the necessary time to alert the emergency services.

Strengths and limitations

Owens et al. (2019) conducted the first (to their knowledge) empirical study on bystander interventions for suicide prevention in public places. Their research shows how lay people intervene (in public places where someone is at risk of suicide) using three effective steps: recognition of the need to intervene, the intervention acts per se, and what happens after the intervention.

The first step of ‘bursting the bubble’ is very similar to Samaritans known campaign ‘Small Talk Saves Lives’, which includes ways to approach someone who might be suicidal and interrupt someone’s suicidal thoughts. Samaritans also suggest potential signs that someone might need help (e.g. looking withdrawn or upset) and what kind of questions to ask. Lay people should ‘Think SAM’ and 1) start the conversation, 2) alert other, 3) move people to safety.

This study by Owen et al. (2019) adds new evidence to the body of literature and highlights details about the process of intervening in a suicide attempt. In addition, the qualitative and in-depth nature of the study helped the researchers dive deep into both perspectives of the individual thinking of taking their own life and the bystander who intervenes; creating a full and detailed picture.

However, one of the limitations of the study is that the lay people included in the research included ‘off-duty’ professionals who may be trained to spot people at risk of suicide and may have had training about effective ways to intervene when someone around them is feeling suicidal. Further research should be conducted looking at the differences between lay people with no prior training or experience, mental health professionals and local authority professionals as it may provide an accurate depiction of bystander intervention in public places.

New evidence by Owens et al. (2019) support further the campaign ‘Small Talk Saves Lives’ by Samaritans in effort to prevent suicide in public places.

This recent qualitative research supports the Samaritans ‘Small Talk Saves Lives’ campaign focusing on how to prevent suicide in public places.


This study has implications for public health policy and future research about suicide prevention. Having a nuanced understanding of how to best intervene and which steps to follow can lead to the development of new guidelines and targeted interventions. The results have the potential to educate members of the public on how to spot someone at risk. However, we need to keep in mind that in order to intervene, bystanders need to be observant and open to the changing environment. Simple, concise and manageable public information campaigns are needed not only to educate bystanders in interventions, but also to increase their confidence to identify signs and intervene.

Furthermore, Owens et al. (2019) research has created more questions around the nature of interventions. Lisa Marzano and colleagues from Middlesex University and Westminster University have joined forces with Samaritans, Network Rail and British Transport Police to explore bystander interventions and suicide in public places. Their aim is to understand what makes a safe and effective intervention and find new ways to encourage the general public to intervene when someone around them is at risk.

Simple, concise and manageable public information campaigns are needed not only to educate bystanders in interventions, but also to increase their confidence to identify signs and intervene.
