The risk-taking and self-harm inventory for adolescents: Development and psychometric evaluation
In this study, we report on the development and psychometric evaluation of the Risk-Taking (RT) and Self-Harm (SH) Inventory for Adolescents (RTSHIA), a self-report measure designed to assess adolescent RT and SH in community and clinical settings. 651 young people from secondary schools in England ranging in age from 11.6 years to 18.7 years and 71 young people referred to mental health services for SH behavior in London between the ages of 11.9 years and 17.5 years completed the RTSHIA along with standardized measures of adolescent psychopathology. Two factors emerged from the principal axis factoring, and RT and SH were further validated by a confirmatory factor analysis as related, but different, constructs, rather than elements of a single continuum. Inter-item and testâretest reliabilities were high for both components (Cronbach's α = .85, rtt = .90; Cronbach's α .93, rtt = .87), and considerable evidence emerged in support of the measure's convergent, concurrent, and divergent validity. The findings are discussed with regard to potential usefulness of the RTSHIA for research and clinical purposes with adolescents
The neural correlates of emotion processing in juvenile offenders
Individuals with severe antisocial behaviour often demonstrate abnormalities or difficulties in emotion processing. Antisocial behaviour typically onsets before adulthood and is reflected in antisocial individuals at the biological level. We therefore conducted a brain-based study of emotion processing in juvenile offenders. Male adolescent offenders and age-matched non-offenders passively viewed emotional images whilst their brain activity was recorded using electroencephalography. The early posterior negativity (EPN) and the late positive potential (LPP) components were used as indices of emotion processing. For both juvenile offenders and non-offenders, the EPN differentiated unpleasant images from other image types, suggesting that early perceptual processing was not impaired in the offender group. In line with normal emotion processing, the LPP was significantly enhanced following unpleasant images for non-offenders. However, for juvenile offenders, the LPP did not differ across image categories, indicative of deficient emotional processing. The findings indicated that this brain-based hypo-reactivity occurred during a late stage of cognitive processing and was not a consequence of atypical early visual attention or perception. This study is the first to show attenuated emotion processing in juvenile offenders at the neural level. Overall, these results have the potential to inform interventions for juvenile offending

The significance of insecure attachment and disorganization in the development of children's externalizing behavior: A meta-analytic study
This study addresses the extent to which insecure and disorganized attachments increase risk for externalizing problems using meta-analysis. From 69 samples (N = 5,947), the association between insecurity and externalizing problems was significant, d = 0.31 (95% CI: 0.23, 0.40). Larger effects were found for boys (d = 0.35), clinical samples (d = 0.49), and from observation-based outcome assessments (d = 0.58). Larger effects were found for attachment assessments other than the Strange Situation. Overall, disorganized children appeared at elevated risk (d = 0.34, 95% CI: 0.18, 0.50), with weaker effects for avoidance (d = 0.12, 95% CI: 0.03, 0.21) and resistance (d = 0.11, 95% CI: â0.04, 0.26). The results are discussed in terms of the potential significance of attachment for mental health

Poverty, early care and stress reactivity in adolescence: findings from a prospective, longitudinal study in a low-middle income country
A considerable body of evidence suggests that early caregiving may affect the short-term functioning and longer-term development of the hypothalamic-pituitary adrenocortical (HPA) axis. Despite this, most research to date has been cross-sectional in nature or restricted to relatively shortâterm longitudinal follow-ups. More importantly, there is a paucity of research on the role of caregiving in low and middle income countries, where the protective effects of high quality care in buffering the childâs developing stress regulation systems may be crucial. In this paper, we report findings from a longitudinal study (N = 232) conducted in an impoverished peri-urban settlement in Cape Town, South Africa. We measured caregiving sensitivity and security of attachment in infancy and followed children up at age 13 years, when we conducted assessments of HPA axis reactivity, as indexed by salivary cortisol during the Trier Social Stress Test. The findings indicated that insecure attachment was predictive of reduced cortisol responses to social stress, particularly in boys, and that attachment status moderated the impact of contextual adversity on stress responses: secure children in highly adverse circumstances did not show the blunted cortisol response shown by their insecure counterparts. Some evidence was found that sensitivity of care in infancy was also associated with cortisol reactivity, but in this case insensitivity was associated with heightened cortisol reactivity, and only for girls. The discussion focuses on the potentially important role of caregiving in the long-term calibration of the stress system and the need to better understand the social and biological mechanisms shaping the stress response across development in low and middle income countries
Neural correlates of face familiarity in institutionalised children and links to attachment disordered behaviour
BACKGROUND: One of the most well-documented sequelae of early maltreatment and institutionalisation is attachment problems, including behaviours under the labels of reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED). Despite growing evidence of the neurobiological effects of institutionalisation, the neural correlates of these behavioural patterns are largely unknown. METHODS: The current study examined effects of both institutionalisation in general and attachment disordered behaviour, in particular, on brain-based markers of face processing, in 100 Portuguese children (70 currently institutionalised, 30 continuously raised by their families). Children's neural processing of caregiver's and stranger's faces was assessed with Event-Related Potentials (ERPs). RESULTS: Compared to children from the community, institutionalised children showed smaller amplitudes in the N170, to both stranger and caregiver faces. Amongst the institutionalised group, living in a setting with a higher children-to-caregivers' ratio was associated with smaller P400 amplitudes. The display of DSED symptoms was associated with a smaller P1 to both faces, as well as a reduced differentiation between faces in P400 amplitudes and smaller P400 to the stranger's face. In contrast, RAD symptoms were not associated with any ERP measures. CONCLUSIONS: Results replicate previously reported hypoactivation in institutionalised children, in a less-globally deprived setting than past work, indicating that such a pattern is associated with lack of individualised care and increased symptoms of DSED
The perspectives of senior researchers in applied disciplines on the current state of developmental attachment research: an interview study
Based on interviews with leading researchers and researcher-clinicians in fields allied to attachment research, this paper describes participantsâ perceptions of contemporary attachment research in the developmental tradition. Semi-structured qualitative interviews were conducted with 13 research leaders in applied disciplines cognate to attachment research. Participants perceived attachment research as having played a foundational role for developmental science, including highlighting the importance of a developmental perspective and attention to early caregiving experiences. They also identified important contemporary strengths in developmental attachment research, including the observational acuity and insightfulness of its measures, its attention to dyadic processes in contrast to much of biomedicine, the development of a number of attachment-based interventions with well-articulated mechanisms of action, and the capacity of developmental attachment concepts to resonate with clinical and popular audiences. However, participants suggested that the developmental tradition is also perceived as having a comparatively high âcost of entry,â and consequently they warned that it has become somewhat separated from wider developmental science, with its growing prominence of biological research, scalability of methods, and less reliance on theory. Participants perceived both strengths and weaknesses to contemporary developmental attachment research. However they felt that the classic concerns of developmental attachment research were placing the field potentially at odds with current trends in developmental science

Childâs oxytocin response to mother-child interaction: the contribution of child genetics and maternal behavior
The oxytocinergic system is a primary biological system involved in regulating a childâs needs for bonding and for protection from threats. It is responsive to social experiences in close relationships, though evidence across studies is not entirely consistent. Guided by previous literature, we investigated individual and environmental factors predicting and presumably affecting childrenâs oxytocin (OT) response during mother-child interaction. by focusing on childrenâs OXTR genotype, and maternal behavior, respectively. This was achieved by assessing salivary OT levels of 88 Portuguese preschoolers prior to and following a mother-child interaction task, and by genotyping childrenâs OXTR SNP rs53576. Maternal interactive behavior was assessed using Ainsworth scales.
Results indicated that child genotype and motherâs sensitive responsiveness interacted in predicting change in child OT concentrations from before to after the interaction. Specifically, Genotypic differences emerged under conditions of low maternal sensitive responsiveness: OT levels increased over time for children with the GG genotype when maternal sensitive responsiveness was low, but no such genotypic differences were evident when mothers were highly sensitive responsive.
Findings provide preliminary support for the notion that increased understanding of childrenâs OT and close relationships requires consideration of both individual and environmental factors.info:eu-repo/semantics/acceptedVersio

The Collaboration on Attachment Transmission Synthesis (CATS): A Move to the Level of Individual-Participant-Data Meta-Analysis
Generations of researchers have tested and used attachment theory to understand childrenâs development. To bring coherence to the expansive set of findings from small-sample studies, the field early on adopted meta-analysis. Nevertheless, gaps in understanding intergenerational transmission of individual differences in attachment continue to exist. We discuss how attachment research has been addressing these challenges by collaborating in formulating questions and pooling data and resources for individual-participant-data meta-analyses. The collaborative model means that sharing hard-won and valuable data goes hand in hand with directly and intensively interacting with a large community of researchers in the initiation phase of research, deliberating on and critically reviewing new hypotheses, and providing access to a large, carefully curated pool of data for testing these hypotheses. Challenges in pooling data are also discussed
