The impact of childhood adversities on the development of Posttraumatic Stress Disorder (PTSD) in the Northern Ireland population

Suicide in Northern Ireland: epidemiology, risk factors, and prevention

The rates of suicide and self-harm in Northern Ireland are high, and have increased from 143 registered suicides in 1996 to 313 in 2010 and 318 in 2015. This Review summarises the epidemiology of suicidal behaviour, as well as the evidence from a small number of studies that have identified risk factors associated with high suicide rates in Northern Ireland. These risk factors were mental illness, trauma, exposure to the conflict known as the Troubles, deprivation, relationship problems, employment difficulties, financial difficulties, being LGBT, childhood adversities, and alcohol or drug use. We highlight the key challenges and opportunities for suicide prevention, emphasising a so-called lifespan approach. More needs to be done to address the relationship between substance misuse and suicide. Future research and prevention efforts should also focus on the transgenerational effect of the conflict, youth suicide, suicide prevention in minority groups, and the criminal justice context. The provision of and access to suicide-specific psychosocial interventions need to be prioritised, more support for people in crisis is required, as well as interventions for mental illness. Protect Life 2, the national suicide prevention strategy, needs to be implemented in full. Given the legacy of conflict in Northern Ireland, all suicide prevention efforts should be trauma informed.

Life within a limited radius: Investigating activity space in women with a history of child abuse using global positioning system tracking

Early experiences of childhood sexual or physical abuse are often associated with functional impairments, reduced well-being and interpersonal problems in adulthood. Prior studies have addressed whether the traumatic experience itself or adult psychopathology is linked to these limitations. To approach this question, individuals with posttraumatic stress disorder (PTSD) and healthy individuals with and without a history of child abuse were investigated. We used global positioning system (GPS) tracking to study temporal and spatial limitations in the participants’ real-life activity space over the course of one week. The sample consisted of 228 female participants: 150 women with PTSD and emotional instability with a history of child abuse, 35 mentally healthy women with a history of child abuse (healthy trauma controls, HTC) and 43 mentally healthy women without any traumatic experiences in their past (healthy controls, HC). Both traumatized groups—i.e. the PTSD and the HTC group—had smaller movement radii than the HC group on the weekends, but neither spent significantly less time away from home than HC. Some differences between PTSD and HC in movement radius seem to be related to correlates of PTSD psychopathology, like depression and physical health. Yet group differences between HTC and HC in movement radius remained even when contextual and individual health variables were included in the model, indicating specific effects of traumatic experiences on activity space. Experiences of child abuse could limit activity space later in life, regardless of whether PTSD develops.
