• Theories of suicide.
• Characteristics of deaths by suicide in NI.
• Suicidal behaviour in NI (ideation, plans and
attempts).
• Mapping theories to prevention.
Durkheim’s Theory (1897/1951)
Degrees of imbalance of social integration and moral regulation.
Egoistic. Result of a weakening of the bonds that normally integrate
individuals into the collectivity: in other words a breakdown of social
integration.
Altruistic. Occurs in societies with high integration, where individual
needs are seen as less important than the society's needs as a whole.
Anomic: Considered the product of moral deregulation and a lack of
definition of legitimate aspirations through a restraining social ethic
(e.g. religion).
Fatalistic: person prefers to die than to carry on living within their
society.
Schneidman’s Theory of Suicide
• Suicide = solution to psychological pain (Psychache).
• Goal orientated behaviour with annihilation of
consciousness or pain as its outcome.
• Unmet psychological need describes the stressor leading
to the suicidal decision.
• Emotion of overwhelming hopelessness.
• Reduced cognitive state serves to desensitize the
individual and heighten ambivalence.
• Alternatives to suicide are constricted by current
perceptual state.
Schneidman’s ‘Psychache’ (1996)
• Unmet need, relative to perceived norms heightens risk of suicide,
determined by learned responses during early experience.
• Thwarted love: a frustrated need for comfort and alliance;
• Fractured control: loss or perceived lack of autonomy;
• Assaulted self-image: individual need for affiliation and avoidance of
shame;
• Ruptured key relationships: responses to interpersonal difficulties and
grief experienced by loss of a nurturing presence;
• Excessive anger, rage and hostility = a thwarted need for dominance.
Joiner’s interpersonal-psychological theory of
suicidal behaviour (2005)
• Thwarted belongingness,
• Perceived burdensomeness,
• Acquired capability for suicide.
Thwarted belongingness
• Feeling disconnected from others, reporting a sense of isolation .
• Alternatively, while others might care, nobody can relate .
• Dysfunctional automatic thoughts: characteristic of mental illness and
skew the individuals' perceptions.
• Estrangement from others who have not experienced the same
overwhelming emotions, regardless of prior connection.
Perceived burdensomeness
• Distorted automatic thoughts, unable to contribute to society.
• They are not making any worthwhile contributions to the world
around them.
• Perceived liability: others' lives would be improved if they were to
disappear.
• Therapeutic interventions: Cognitive behavioral approaches such as
behaviour activation and cognitive restructuring can increase positive
experiences while diminishing the tendency to view the environment
through distorted lenses. Goal setting and attainment may increase
self-sufficiency.
Acquired capability for suicide
• In order to enact lethal self-harm, an individual must habituate to physical
pain and the fear of death.
• Person must become accustomed to pain and fear. Habituation, occurs
through repeated exposure.
• Physical pain becomes less pronounced over time when our body becomes
accustomed to the experience.
• Those who frequently self-harm experience pain analgesia - the absence of
pain - during self-injury episodes.
• Repeated attempts contribute to acquired capability.
• Experiences that involve witnessing pain and violence, even in the absence
of physical pain, can contribute to the acquired capability.

Suicidal Behaviour in Northern Ireland
NI Study of Health and Stress (World Mental Health Survey Initiative;
68% rr, n=4340).
• Ideation: Seriously considered suicide.
• Females: 10.6%, Males: 7%
• Made a plan for suicide.
• Females: 2.5%, Males: 2.4%
• Suicide attempt.
• Females: 4.3%, Males: 2.3%

WHY?
• Conflict experience is protective.
OR
• Conflict associated with increased likelihood of death on first
attempt.
 Look at theories of suicide: Joiner/ Klonsky/ O’Connor
Why do people die by suicide?
• Suicide is a goal directed behaviour to address
unbearable pain.
• Pain + Hopelessness  thoughts of suicide (ideation).
• Connectedness prevents enaction.
• If pain > connectedness  plan.
• Whether this leads to death is dependent upon capability
or access to means.
• If total capability > fear of attempting attempt.
The Northern Ireland Context
• Conflict increases connectedness.
• Post conflict: reduced connectedness (especially those
who have been most affected).
• Exposure to pain  habituation (less fear/ more
expertise).
• Access to means.
• Cognitive access to means: Information.
Suicide prevention: The next steps
• Creating a culture of social integration and connectedness.
• Looking at emotional responses to life events.
• Evidence based treatments for mental disorders.
• Seeking help is a sign of strength.
• Considering acquired capability and access to means (including
cognitive access to means).
• Improving the validity of the data on suicide.
