First Nations adults continue to experience significant health disparities compared to non-First Nations adults in Canada. Ongoing difficulties associated with intergenerational trauma among First Nations peoples may be examined using the adverse childhood experiences (ACEs) model, which measures various forms of abuse, neglect, and household dysfunction. We examined prevalence rates of ACEs and physical and mental health outcomes within a predominately First Nation sample of clients seeking substance use treatment from a First Nations-led treatment facility. The prevalence of ACEs was higher than national averages and previous data collected with broader Indigenous samples in Canada. Descriptive analyses of ACEs and health outcomes for those seeking First Nations-led substance use treatment showed these participants had more chronic health difficulties co-morbid with clinical levels of problematic substance use. To improve ongoing best-treatment options for those seeking substance use treatment, continued assessment and promotion of broader aspects of health and wellbeing are required, including the balance of physical, emotional, spiritual, and mental health and wellbeing across a lifespan.

Indigenous youth are disproportionately represented among youth experiencing homelessness in Canada and are at an increased risk for mental health and substance use problems compared to non-Indigenous youth experiencing homelessness. Research is needed that considers how best to support Indigenous youth in acquiring and maintaining stable housing. Indigenous youth peer mentorship is one possible mechanism that warrants consideration, as Indigenous youth who have previously been homeless can share experience with the barriers that other youth encounter as well as skills that may be well-suited to facilitate hope and understanding to other homeless youth. In the present study, we examined the process by which Indigenous peer mentors engage in a peer-driven project designed to support other Indigenous youth experiencing homelessness in Northwestern Ontario. This process was documented through qualitative interviews with three peer mentors and three staff, as well as ethnographic fieldnotes. Thematic analyses revealed that peer mentorship positions appear to be useful for the Indigenous youth who engage in them, as these positions provide them with a paid avenue to engage in advocacy and support others with similar experiences as them, while simultaneously increasing their cultural connectedness, confidence, self-esteem, self-awareness, and ability to advocate for their own needs. The present study also yielded important considerations for organizations implementing Indigenous youth peer mentorship positions, including offering training and providing opportunities for cultural engagement, avoiding tokenism, being cognizant of possible dual-relationships, and supporting peer mentors who may be grappling with personal difficulties outside of their roles.

This study examined data from the 2017 Aboriginal Peoples Survey to consider predictors of land-based activity engagement. We hypothesized that higher self-reported mental and physical health scores, an increased sense of cultural belonging, living in a rural community, and no prior individual or family history of residential school attendance would predict a higher frequency of land-based activity engagement among First Nations individuals living off-reserve. Results from linear regression analyses suggested that an increased sense of cultural belonging, being male, and living in a rural community with a population of less than 1000 people were significant predictors of the frequency of land-based activity engagement. With these preliminary findings, further research can explore how physical and mental health outcomes influence the frequency of land-based activity engagement, in addition to how community-specific indicators may promote higher frequency of these activities, particularly among First Nations individuals living off-reserve.

Adverse childhood experiences (ACEs) have been associated with increased mental health difficulties across a lifespan. Given increased health disparities among Indigenous populations compared to non-Indigenous populations, screening for ACEs is particularly relevant as it can inform future preventative care and treatment approaches. There has been no literature to date about how to best integrate these practices into routine psychological assessment with Indigenous clients. We describe five recommendations for assessing ACEs with Indigenous clients that are based on anecdotal research and clinical practices but aligned with standard evidence-based assessment practices. The preliminary recommendations for ACE assessment are: (1) determine the relevance of the assessment, (2) convey a sense of purpose and meaning during assessment, (3) use therapeutic assessment techniques, (4) use the ACE model for further client psychoeducation, and (5) use culturally relevant measurement techniques. These suggestions may provide a more meaningful and culturally relevant psychological assessment, but research is needed to support them.

Approaches that root national climate strategies in local actions will be essential for all countries as they develop new nationally determined contributions under the Paris Agreement. The potential impact of climate action from non-national actors in delivering higher global ambition is significant. Sub-national action in the United States provides a test for how such actions can accelerate emissions reductions. We aggregated U.S. state, city, and business commitments within an integrated assessment model to assess how a national climate strategy can be built upon non-state actions. We find that existing commitments alone could reduce emissions 25% below 2005 levels by 2030, and that enhancing actions by these actors could reduce emissions up to 37%. We show how these actions can provide a stepped-up basis for additional federal action to reduce emissions by 49%—consistent with 1.5 °C. Our analysis demonstrates sub-national actions can lead to substantial reductions and support increased national action., Climate action from local actors is vital in achieving nationally determined contributions under the Paris Agreement. Here the authors show that existing commitments from U.S. states, cities and business could reduce emissions 25% below 2005 levels by 2030, with expanded subnational action reducing emissions by 37% and federal action by up to 49%.

Health concerns in Indigenous people are often greater in comparison to those in non-Indigenous populations, including increased rates of chronic diseases and mental health concerns. Adverse childhood experiences (ACEs) may be an explanatory variable for such heightened rates of mental and physical health difficulties for Indigenous populations as these communities have experienced a lack of adequate health care due to remoteness, historical traumas, cultural insensitivity, racism, and perpetuating systemic discrimination. To date, relatively few studies have examined ACEs within an Indigenous population and their relevance to both physical and mental health outcomes. The present study explored existing ACE literature relevant to Indigenous populations and mental or physical health outcomes by retrieving and organizing available ACE literature. A systematic review was conducted using 14 electronic databases of peer-reviewed literature and 18 grey literature databases. Twenty-one publications investigating general health outcomes and prevalence of ACEs met eligibility criteria. ACEs were reported to be higher in Indigenous populations when compared to non-Indigenous population. Higher ACE scores for Indigenous participants were associated with increased rates of suicidality and psychological distress. Protective factors to reduce the impact of ACEs were cultural identity and connectedness, education, social support, and psychological resilience. Future research may further explore the relationship between ACE scores and protective factors, varying prevalence within specific sub-populations, and consistent reporting of outcomes across studies. Ongoing research has the potential to clarify existing dose–response relationships between early traumatic experiences and current health disparities experienced within some Indigenous communities.

Resilience within public health is conceptualized to be fostered through individual, community, and systemic initiatives that promote capacity through interconnected primary, secondary, and tertiary health interventions. Within community public health settings, particularly for Canadian Indigenous communities, an emphasis on interconnected, multisystemic interventions that promote resilience can be particularly useful. Fostering resilience within Indigenous health seeks to prioritize unique needs of individuals and communities, through both process- and outcome-based measurement. Given that Indigenous individuals’ needs may differ from non-Indigenous populations in Canada, careful consideration of how to best conceptualize, measure, and promote resilience is required. Tools such as the Native Wellness Assessment and the First Nations Mental Wellness Continuum Framework can be helpful to both measure and conceptualize resilience, as they can provide insight on what is considered to be best practices to increasing wellness within Indigenous communities. Such tools continue to prioritize the multisystemic promotion of resilience.

There is a high prevalence of Indigenous youth experiencing either precarious housing or homelessness in northwestern Ontario. Given that Indigenous pathways to homelessness can differ from non-Indigenous youth, interventions that address homelessness must also adapt to meet diverse needs. The Housing Outreach Program Collaborative (HOP-C) is a tertiary prevention intervention designed to provide congruent housing and peer and mental health supports for youth experiencing homelessness in Toronto, Ontario. Less is known regarding its adaptability to adequately serve Indigenous youth in northwestern Ontario. This study assessed the preliminary effectiveness and feasibility of an adaptation of the HOP-C North program for transitional aged Indigenous youth exiting homelessness in Thunder Bay, Ontario. Participants completed premeasures (n = 15) and postmeasures (n = 8) as well as qualitative interviews regarding their experiences in the program. Qualitative interviews were also conducted with staff (n = 14) engaged in implementing the program. After completing the HOP-C North program, participants reported improvements in a number of outcomes, including increased educational enrollment, attainment of employment, reduced hospitalizations, and increased engagement in clinical mental health services. Specific program aspects that participants found helpful included increased program flexibility, accessibility, emphasis on relationships, relevance of programming, fostering participant autonomy, and an adaptive approach to program implementation. These findings suggest that the HOP-C North model, when adapted, is a helpful program for Indigenous youth. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Background Conducting culturally-relevant research with Indigenous populations requires a balance of approaches that benefit Indigenous communities, while perceiving and mitigating the potential risk of harm when engaging in research-related activities. Reducing the burden of research is especially useful for research with Indigenous populations as ongoing systemic marginalization and discrimination through historical colonial practices may result in a higher likelihood of experiencing harm from research activities. One way to ensure that stakeholder experiences with the research processes are not burdensome, and to understand how study implementation practices are perceived across research teams, supporting organizations, and individual participants is to build this into the study method. Objective The current study describes stakeholder experiences within a broader research study, entitled the First Nations ACE Study, which examined early childhood experiences and health outcomes for Indigenous people seeking treatment for substance use. Participants and setting Five treatment centre staff participated in ongoing consultations with the research team and described their experiences within a Community-Based Participatory Research (CBPR) study. Method A document review of client satisfaction questionnaires of seventy-five participants provided quantitative feedback on experiences in addition to qualitative interviews with staff. Results Overall, experiences of both treatment centre staff and clients were generally positive. Additional results described the importance of continuous stakeholder participation, and ongoing study adaptations to remain aligned with CBPR approaches as pressure for expediency and convenience have the potential to encroach upon CBPR values. The study method was described to mitigate participant and staff burden, as well as risk of participant harm. Conclusions Directions for future research are discussed, including discussion of modifications that will be made to future iterations of the presented research study.

Throughout history, humans have settled in areas of high biodiversity. Today these areas are home to our biggest urban centers with biodiversity at increasing risk from escalating cumulative threats. Identifying the management strategies to conserve species within such regions, and ensuring effective governance to oversee their implementation, presents enormous challenges. Using a novel Priority Threat Management (PTM) approach that calculates the cost‐effectiveness of conservation action and co‐governance, we discover that the 102 species at risk of local extinction within Canada's most diverse, heavily urbanized coastal region, the Fraser River estuary, require urgent investment in management strategies costing an estimated CAD$381 M over 25 years. Our study also suggests that co‐governance underpins conservation success in urban areas, by increasing the feasibility of management strategies. This study underscores that biodiversity conservation in heavily urbanized areas is not a lost cause but does require strategic planning, attention to governance, and large‐scale investment.

Background The relationship between adverse childhood experiences (ACEs) and detrimental poor mental health outcomes has been increasingly explored within scientific literature since the original ACE study was published by Felitti et al. (1998). Given that deficits in executive functions (EF) are prominent in most forms of psychopathology across the lifespan, there is utility in considering how ACEs relate to EF outcomes. Objective To consolidate the research to date on the relationship between ACEs and EF outcomes among child samples. Methods A systematic review was conducted that included 16 scientific databases and 17 grey literatures. Results Across 36 studies, many examined EF related to forms of maltreatment (e.g. abuse, neglect, and exposure to intimate partner violence) and found a strong relationship between maltreatment and EF deficits among children. Similarly, family member mental illness (maternal depression in particular) was associated with poor EF outcomes. The relationship between other ACEs and EF outcomes have not been uniquely examined, including intimate partner violence and family member incarceration. Conclusions This review acts as a preliminary step towards broader understanding of outcomes related to early childhood experiences through the consideration of EFs. Through documentation of such relationships, it is possible to consider how prevention and treatment approaches may be improved.

Background Early life experiences may alter personality outcomes across the lifespan. Extremely low birth weight (ELBW) survivors appear to have a particular personality ‘type’ marked by increased levels of cautiousness and social conformity. It is, however, unclear if the experience of child sexual abuse (CSA) can alter this outcome. Methods We utilized data from a prospective, longitudinal, birth cohort of ELBW survivors to examine the personality characteristics in the third and fourth decades of life of those exposed to CSA versus those who were not. Results At age 22–26 years, ELBW survivors who had experienced CSA were less likely to display social conformity (p Conclusions ELBW survivors who have experienced CSA appear less likely to socially conform, are less cautious, and may experience higher levels of neuroticism in their 20s and 30s than those who were not exposed. These findings support the possibility that significant childhood experiences may lead to stable alterations in personality through the fourth decade of life.

Introduction Perinatal and later postnatal adversity (e.g., child sexual abuse) are predictors of psychopathology across the lifespan. However, little is known about the impact of the joint effects of perinatal and postnatal adversity on the longitudinal trajectories of mental health problems from adolescence through adulthood. Method We utilized data from a prospective, longitudinal birth cohort of extremely low birth weight (ELBW; 2500 g) control participants. Self-report data on internalizing (depression, anxiety) and externalizing (antisocial) problems were collected at 12–16, 22–26, and 30–35 years of age. Results A birth weight by child sexual abuse (CSA) interaction was observed such that ELBW survivors exposed to CSA had higher levels of internalizing problems from adolescence through adulthood than NBW participants exposed to CSA. Differences remained significant after adjustment for covariates. Likewise, ELBW survivors exposed to CSA had higher levels of internalizing problems from adolescence through adulthood than ELBW participants who were not exposed to CSA. Limitations Findings are limited by sample attrition due to the longitudinal nature of the study spanning over 30 years as well as the retrospective nature of child sexual abuse reporting. Conclusions Exposure to both perinatal and later postnatal adversity leads to persistently higher internalizing problems than exposure to either adversity alone over more than two decades. These findings suggest that individuals exposed to perinatal adversity may be especially vulnerable to, and persistently affected by, childhood adversity, particularly in the form of depression and anxiety.

Preterm birth and exposure to childhood sexual abuse (CSA) are early physiological and psychological adversities that have been linked to reduced social functioning across the lifespan. However, the joint effects of being born preterm and being exposed to CSA on adult social outcomes remains unclear. We sought to determine the impact of exposure to both preterm birth and CSA on adult social functioning in a group of 179 extremely low birth weight (ELBW; 2500 g) participants in the fourth decade of life. Social outcome data from a prospective, longitudinal, population-based Canadian birth cohort initiated between the years of 1977 and 1982 were examined. At age 29–36 years, ELBW survivors who experienced CSA reported poorer relationships with their partner, worse family functioning, greater loneliness, lower self-esteem and had higher rates of avoidant personality problems than those who had not experienced CSA. Birth weight status was also found to moderate associations between CSA and self-esteem (P=0.032), loneliness (P=0.021) and family functioning (P=0.060), such that the adverse effects of CSA were amplified in ELBW survivors. Exposure to CSA appears to augment the adult social risks associated with perinatal adversity. Individuals born preterm and exposed to CSA appear to be a group at particularly high risk for adverse social outcomes in adulthood.

The high prevalence of child sexual abuse (CSA) is concerning, particularly as survivors are at increased risk for multiple adverse outcomes, including poor mental health across the lifespan. Children born at an extremely low birth weight (ELBW;1000g) and who experience CSA may be a group that is especially vulnerable to psychopathology later in life. However, no research has considered the mental health risks associated with being born at ELBW and experiencing CSA. In this study, we investigated the mental health of 179 ELBW survivors and 145 matched normal birth weight (NBW;2500g) participants at ages 22-26 and 29-36. At age 22-26, CSA was associated with increased odds of clinically significant internalizing (OR=7.32, 95% CI: 2.31-23.23) and externalizing (OR=4.65, 95% CI: 1.11-19.51) problems among ELBW participants exposed to CSA compared to those who did not, though confidence intervals were wide. At age 29-36, CSA was linked to increased odds of any current (OR=3.43, 95% CI: 1.08-10.87) and lifetime (OR=7.09, 95% CI: 2.00-25.03) non-substance use psychiatric disorders, however, this did not hold after adjustment for covariates. Statistically significant differences in mental health outcomes were not observed in NBW participants exposed to CSA compared to NBW participants who were not exposed. Survivors of significant perinatal adversity who are also exposed to CSA may be at higher risk for psychopathology through the fourth decade of life.
