Research & Current Projects

In our lab we are interested in factors that increase risk and provide protection during pre-adolescence and adolescent development. Our work integrates research on both normative and atypical developmental trajectories with the goal of understanding how we can support healthy development and intervene during critical transitions to reduce risk. Over the past decade we have focused on understanding risk and protective factors among adolescent girls and boys at high risk for violence and victimization. Our eight-year longitudinal study with these teens has produced important findings on the complexity of their mental health needs, the social contexts that place them at risk and the personal and relational factors that buffer them from adversity.

Strengthening Parent-Teen Relationships: Pathways to Improving Mental Health and Wellbeing of Aboriginal Youth and Caregivers

The rate of suicide among Aboriginal youth is approximately five to six times that of non-Aboriginal youth. Extensive research has demonstrated that attachment security within the adolescent-caregiver relationship is associated with significantly lower levels of depression and suicidal ideation. The Connect Parent Group program is an attachment based intervention with demonstrated effectiveness that has been developed and evaluated in communities across British Columbia; however uptake has been more gradual among Aboriginal caregivers. Over the last 18 months, in collaboration with our partners in Aboriginal communities, we have held a series of focus groups and interviews with service providers, program facilitators, community leaders and caregivers living on-reserve and found that there was universal interest among those with whom we spoke to co-create an adapted version of the Connect program that would: strengthen attachment between caregivers and teens; honour the inherent strengths of Aboriginal caregivers; and respect traditional teachings related to parenting. This project of adaptation, implementation and evaluation of the Connect program for Aboriginal caregivers will move forward through four developmental phases. First, we will establish a Reflecting Team consisting of Aboriginal service providers, community members and leaders who will guide the process of adapting the program. Next we will work with the Reflecting Team to identify adaptations to the program and appropriate measures for evaluating the program that honour both Indigenous and Western ways of knowing. In phase three we will pilot the adapted program in at least six diverse Aboriginal communities representing urban and rural settings as well as on- and off-reserve communities. Finally, we will work with communities to identify barriers to program uptake and produce a detailed implementation plan that will support the future scale-up of the intervention in diverse Aboriginal communities. 


Effectiveness of a Relational Intervention in Reducing Violence and Victimization in At-risk Adolescent Girls and Boys

Entry into adolescence is marked by profound biological and social relational changes for girls and boys. It is also a time when aggression and violence become a part of many young people’s lives. Physical aggression, social aggression (aggressive acts that harm social relationships, humiliate or demean others) and violence increase for girls and boys when they enter adolescence, peak in mid-adolescence and decline in adulthood. Victimization also rises for girls and boys. The social and economic burden of adolescent violence and aggression is extremely high. New prevention approaches are needed to support young adolescents at this critical turning point. Building on our 8 year longitudinal study of adolescent girls and boys at high risk for violence and aggression, we evaluate the efficacy of an attachment based program for vulnerable girls and boys just prior to their transition to secondary school, when problems tend to escalate. In this study, we examine how sex and gender intersect with social, psychological, genetic, and biological factors to determine intervention outcomes. The proposed research also explores sex and gender in relation to cultural diversity, violence and victimization, and takes steps to better understand the needs of girls and boys in the juvenile justice system.

Strengthening Parent-Teen Relationships to Reduce Risk and Enhance Healthy Development: A Sex and Gender Framework in Translating Research into Practice

The social and economic costs of teen violence and aggression are substantial and rising. Despite recent progress, further research is needed to develop interventions for pre-teens and adolescents, particularly those at the highest level of risk. Few programs have addressed the relevance of gender differences in risk and protective factors, and important questions remain regarding the need for ‘gender sensitive’, ‘gender tailored’ or ‘gender specific’ programming. To be effective interventions must be research driven; based on established knowledge about risk and protective factors; and targeted to sensitive developmental transitions which present different risks for girls and boys. Programs that promote and strengthen relationships between youth and their parents offer considerable promise in enhancing healthy development, and reducing violence, aggression and related mental health and social problems. Building on our eight-year longitudinal study of adolescent girls and boys at high risk for violence, aggression, and poor social and mental health, we developed an attachment focused intervention designed to strengthen parent-teen relationships. The proposed research evaluates the short and long term effectiveness of this program for girls and boys; examines the role of risk and protective factors as determining treatment outcomes; and investigates shared and gender specific social, psychological, genetic and biological factors that underlie change in therapy.

Girls at Risk for Aggression and Antisocial Behaviour: Risk, Resilience and Developmental Trajectories

This research program builds on our longitudinal study of high-risk adolescent youth in Canada and the US obtained through under a CIHR New Emerging Team grant (Aggressive and violent girls: contributing factors, developmental course & intervention strategies) directed by Dr. Marlene Moretti and funded through the Institute of Sex, Gender and Health. The sample was strategically drawn to represent girls at the highest level of risk for engagement in aggression and antisocial behaviour from Canada and the US. A matched sample of adolescent boys was also recruited. Adolescents referred to a provincial centre mandated to serve youth with serious aggressive and antisocial behaviour and youth detained in custody centers were assessed at two time points using a comprehensive protocol that tapped information on behavioural patterns, family, peer and romantic partner life experiences including exposure to maltreatment and other forms of adversity, child mental health problems, social-relational functioning; social cognitive, school and intellectual functioning; self-regulatory capacity; and personality characteristics.

 

This research program extends our follow-up of these youth at three additional points across a five year period. Combined with existing data, this research will permit mapping of trajectories from early adolescence (age 13/14) to early adulthood (age 23/24). New waves of data collection assess a wider range of range of functional domains including adjustment in educational, vocational, romantic and parental roles. In addition, physical health outcomes will be evaluated. Both quantitative and qualitative methods are being used examine issues of cultural and social marginalization. Of particular interest is whether similar themes will emerge across girls of cultural minority status in Canada and the US; and whether experiences are shared across girls growing up in contexts characterized by varying levels of socioeconomic deprivation. This study will generate new findings on developmental trajectories among high-risk Canadian girls. It is the first comparative investigation of risk profiles and trajectories between Canadian and American girls.
