What is Digital Identity? A Transdisciplinary Meta-synthesis
Who do you think you are? An experimental comparison of online and offline identities using NLP techniques
Researchers have been debating whether our online identities are different from our offline identities since technology enabled us to operate in the digital space. This paper advances the online-offline debate by utilizing Natural Language Processing (NLP) techniques to compare identity-related statements across online and offline contexts. Participants (N = 120) completed twenty “I am...” statements in two conditions: one reflecting online ident…
Not All Interventions are Made Equal
This study examined the influence of design “nudges” on bystanders’ willingness to intervene in online harassment using a social media simulation. Utilizing a 2 × 2 experimental design, we tested the ability of key design features (community guidelines and pop-up messaging) to induce a sense of self-efficacy (low/high) and personal responsibility (low/high) and thence to influence intervention levels. Participants ( n = 206) were invited to “beta…
Positive Impacts of Prison-Based Gardening and Horticultural Activities for Previously Incarcerated Individuals
Nature deprivation is common in prison populations, with repercussions that may be contributing to severe mental health issues. Although literature has illuminated countless benefits of nature exposure within prisons, there is little research surrounding the effects of in-prison nature-based activities post-release. To “follow prisoners through the gate,” this research explores post-release reflections of people previously incarcerated (PPIs) in …
What do the Public Understand About Intimate Partner Violence in the Context of Military Veteran Status and PTSD
Intimate Partner Violence (IPV) represents a significant public and social health concern and may present particular complexities in military veteran relationships which are subject to unique stressors including separations, transition to civilian life and increased risk of Post-Traumatic Stress Disorder (PTSD). Public understanding is vital in terms of ensuring access to services and appropriate intervention. However, little is known about the p…
To intervene or not to intervene
Incidents of online harassment are increasing and can have significant consequences for victims. Witnesses (“digital bystanders”) can be crucial in identifying and challenging harassment. This study considered when and how young adults intervene online, with the aim of understanding the applicability of existing theoretical models (i.e., Bystander Intervention Model; Response Decision-Making Framework). Thematic analysis of eight focus groups (UK…
Developing a novel co‐produced methodology to understand ‘real‐world’ help‐seeking in online peer–peer communities by young people experiencing emotional abuse and neglect
BACKGROUND: Recent systematic reviews suggest mediating factors (barriers and facilitators) of help-seeking for children and young people (CYP) with a range of mental health problems but highlight the need for a more robust methodology underpinned by theoretical frameworks. Emotional abuse and neglect is the most prevalent and pervasive form of abuse, with many CYP remaining unknown to professional services. These CYP are underrepresented in help…
The Relevance of Cognitive Behavioral Models of Post-Traumatic Stress Following Child Maltreatment
While it is known that young people exposed to maltreatment or abuse are at elevated risk of developing post-traumatic stress disorder (PTSD), much of our current knowledge of mechanisms that link trauma to childhood PTSD is based on single-incident, often noninterpersonal, trauma. Theoretical models highlight psychological processes of appraisals, memory, and coping as important for the development of PTSD. The aim of this review was to synthesi…
Psychological Interventions for Individuals Bereaved by Homicide
Research has demonstrated that approximately 45–50% of individuals show healthy levels of psychological and physical functioning in the first 12 months post-loss. Homicidal bereavement (loss due to murder or manslaughter) does not appear to follow this pattern. Homicide-related mental health difficulties are a serious problem worldwide, displaying high rates of lifetime incidence, high chronicity, and role impairment. Individuals are at increased…

The Role of Narcissism in Aggression and Violence
It has long been hypothesized that feelings of inferiority or low self-esteem lead individuals to aggress against those they view as being threatening. However, recent studies suggest that it is not just the level of self-esteem but stability that is relevant to understanding this process. As such, researchers have looked to related constructs, such as narcissism, in trying to understand aggressive behaviors. Narcissism is characterized by a diss…
Getting involved
A large number of children around the world are currently living in residential children's homes and a central figure in those settings is the caregiver. The relationship children establish with their temporary caregivers can be a crucial factor in their lives. However, little research has been conducted with caregivers working in institutional settings regarding their experience and the relationship they establish with the children they care for…
A Comparison of Victim and Offender Perspectives of Grooming and Sexual Abuse
This study involved interviews with three female victims of on-line grooming and contact sexual abuse and the three adult males who groomed and abused them. Results indicate that victim and offender dyads most commonly disagreed in their accounts of the sexual elements of the relationship, including initiation; stage when sexualization took place; production of photos and videos; and initiation of contact sexual abuse. The study found that the dy…
In the name of the children”
Under His Spell
The aim of this paper is to highlight key themes within the process of online grooming from the victim's perspective. Eight adolescents who experienced online grooming were interviewed and data were analysed using Thematic Analysis. It was found that participants, who had been both sexually abused online and/or offline, were subjected to a range of grooming experiences. Consistent grooming themes within this sample included: manipulation; decepti…
Differentiating patterns of aggression in the family
The feasibility and prevalence of Reciprocal, Hierarchical and Paternal patterns of family aggression hypothesised by Dixon and Browne (2003) were explored within a sample of maltreating families. The psychological reports of 67 families referred to services for alleged child maltreatment that evidenced concurrent physical intimate partner violence and child maltreatment were investigated. Of these, 29 (43.3%) cases were characterised by hierarch…

Young Children in Institutional Care at Risk of Harm
A recent survey has revealed a large number of young children in institutional care across Europe. Young children placed in institutional care without parents may be at risk of harm. This review considers systematically the research evidence on the impact of institutional care on brain growth, attachment, social behavior, and cognitive development. Analytical epidemiological study designs (i.e., including a control/comparison group) show that you…
