Applying the polyvagal theory to children's emotion regulation: Social context, socialization, and adjustment

Effective emotion regulation is essential for childrens positive development. Polyvagal theory provides a framework for understanding how parasympathetic regulation of cardiac activity contributes to childrens adaptive versus maladaptive functioning. Maintenance of cardiac respiratory sinus arrhythmia (RSA) under social challenge should support emotion regulation and behavioral adjustment. Childrens effective parasympathetic regulation and behavioral adjustment should be supported by appropriate parental socialization. These proposals were evaluated in a short-term longitudinal study of 94 preschool-aged children. Parenting and basal RSA were measured at home, then 6-10 months later behavioral adjustment and RSA in lab baseline and socially challenging contexts were measured. Children with relatively higher RSA in social challenge than at baseline (DeltaRSA) had fewer internalizing problems (IP) and externalizing problems (EP), and better behavioral self-regulation (SR). Mothers who used more negative control had children with lower DeltaRSA, more IP and EP, and less SR. Structural equation modeling showed that vagal regulation mediated associations between maternal negative control and childrens adjustment; maternal negative control did not predict EP or SR after accounting for DeltaRSA. Associations were consistent across boys and girls, with one exception: Higher DeltaRSA was significantly associated with fewer EP in boys only. These findings suggest that the practical significance of physiological regulation might be best revealed in ecologically valid procedures, and that childrens physiological mechanisms of emotion regulation are shaped by their experiences of parental socialization.

Community-based services for homeless adults experiencing concurrent mental health and substance use disorders: a realist approach to synthesizing evidence.

Consultations with community-based service providers in Toronto identified a lack of strong research evidence about successful community-based interventions that address the needs of homeless clients experiencing concurrent mental health and substance use disorders. We undertook a collaborative research effort between academic-based and community-based partners to conduct a systematic evidence synthesis drawing heavily from Pawson’s realist review methodology to focus on both whether programs are successful and why and how they lead to improved outcomes. We examined scholarly and nonscholarly literature to explore program approaches and program elements that lead to improvements in mental health and substance use disorders among homeless individuals with concurrent disorders (CD). Information related to program contexts, elements, and successes and failures were extracted and further supplemented by key informant interviews and author communication regarding reviewed published studies. From the ten programs that we reviewed, we identified six important and promising program strategies that reduce mental health and, to a far lesser degree, substance use problems: client choice in treatment decision-making, positive interpersonal relationships between client and provider, assertive community treatment approaches, providing supportive housing, providing supports for instrumental needs, and nonrestrictive program approaches. These promising program strategies function, in part, by promoting and supporting autonomy among homeless adults experiencing CD. Our realist informed review is a useful methodology for synthesizing complex programming information on community-based interventions.

The New Friends Vignettes: Measuring Parental Psychological Control that Confers Risk for Anxious Adjustment in Preschoolers.

This investigation examined the links between preschoolers’ internalizing problems and anxiety-related social difficulties and two aspects of maternal and paternal psychological control: overprotection and critical control. Some 115 mothers and 92 fathers completed the New Friends Vignettes (NFV), a new measure of psychological control and supportive parenting designed to assess parenting relevant to young children’s internalizing problems and anxiety. Children’s anxious behaviors with peers at daycare or preschool were observed, mothers reported on preschoolers’ internalizing problems, and teachers reported on children’s internalizing problems and isolated behaviors. The NFV scales demonstrated good internal consistency and one-year test—retest reliability for mothers and fathers, and moderate convergent validity with observed parenting for mothers. Maternal overprotection and paternal critical control predicted more internalizing problems and anxious adjustment in preschoolers, with some associations being stronger for sons than daughters. Conversely, paternal supportiveness predicted fewer internalizing difficulties at preschool in daughters only. Children’s anxious behaviors predicted increasing paternal overprotection, and their internalizing problems at home and preschool tended to predict increasing maternal overprotection and critical control. Results support the reliability and validity of the New Friends Vignettes, and are indicative of parent differences in socialization processes, gender differences in risk for internalizing problems, and possible bidirectional pathways of influence in the socialization of internalizing trajectories.

Health Care Provider Attitudes and Beliefs About People Living with HIV: Initial Validation of the Health Care Provider HIV/AIDS Stigma Scale (HPASS)

HIV stigma is a pressing concern for people living with HIV, and particularly when it is perpetuated by health care providers, as it may affect quality of life and access to health care services. The current study describes the development and initial validation of a contextually appropriate HIV stigma scale for health care providers in North America. A ground-up qualitative approach was used to develop the scale, and it was assessed psychometrically with health care trainees across Canada. The measure demonstrates excellent internal consistency reliability and test–retest reliability, as well as convergent and divergent validity. The study supports a tripartite model of HIV stigma consisting of stereotyping, prejudice and discrimination. The scale provides a new tool to assess HIV stigma in health care providers and can be used to inform training, intervention and self-evaluation of stigmatizing attitudes, beliefs and behaviors among providers.

Examining Evidence for Autonomy and Relatedness in Urban Inuit Parenting

Inuit have experienced significant lifestyle changes in the past 50 years. Most recently, urbanization has resulted in greater numbers of Inuit living in urban centres in southern Canada. Little is known about Inuit parenting, and nothing has been published on Inuit parenting in an urban context. The present study sought to address this gap by describing the parenting of Inuit living in a large Canadian city and examining emergent themes for evidence of autonomy and relatedness. In partnership with the Tungasuvvingat Inuit Family Resource Centre, 39 Inuit parents completed an interview about their parenting experiences. Based on interviews, major parenting themes included: child characteristics; parenting behaviours and beliefs; affection and love; stressors; and responsive and respectful parenting. The majority of parenting themes linked to relatedness, although there was evidence of autonomy in both parenting behaviours and child characteristics. Results are interpreted in light of the autonomy—relatedness framework and theoretical implications of findings are discussed.

Understanding the role of Indigenous community participation in Indigenous prenatal and infant-toddler health promotion programs in Canada: A realist review

PURPOSE Striking disparities in Indigenous maternal-child health outcomes persist in relatively affluent nations such as Canada, despite significant health promotion investments. The aims of this review were two-fold: 1. To identify Indigenous prenatal and infant-toddler health promotion programs in Canada that demonstrate positive impacts on prenatal or child health outcomes. 2. To understand how, why, for which outcomes, and in what contexts Indigenous prenatal and infant-toddler health promotion programs in Canada positively impact Indigenous health and wellbeing. METHODS We systematically searched computerized databases and identified non-indexed reports using key informants. Included literature evaluated a prenatal or child health promoting program intervention in an Indigenous population in Canada. We used realist methods to investigate how, for whom, and in what circumstances programs worked. We developed and appraised the evidence for a middle range theory of Indigenous community investment-ownership-activation as an explanation for program success. FINDINGS Seventeen articles and six reports describing twenty programs met final inclusion criteria. Program evidence of local Indigenous community investment, community perception of the program as intrinsic (mechanism of community ownership) and high levels of sustained community participation and leadership (community activation) was linked to positive program change across a diverse range of outcomes including: birth outcomes; access to pre- and postnatal care; prenatal street drug use; breast-feeding; dental health; infant nutrition; child development; and child exposure to Indigenous languages and culture. CONCLUSIONS These findings demonstrate Indigenous community investment-ownership-activation as an important pathway for success in Indigenous prenatal and infant-toddler health programs.

Predictors of the integration of Sri Lankan Tamil refugees in Canada: pre-migration adversity, mental health, personal attributes, and post-migration experience

Purpose – Refugees integrate less successfully than other immigrants. Pre-migration stress, mental disorder and lack of human capital are the most popular explanations, but these propositions have received little empirical testing. The current study of Sri Lankan Tamils in Toronto, Canada, examines the respective contributions of pre-migration adversity, human capital, mental health and social resources in predicting integration. The paper aims to discuss these issues. Design/methodology/approach – Participants are a probability sample of 1,603 Sri Lankan Tamils living in Toronto, Canada. The team, with a community advisory council, developed structured interviews containing information about pre- and post-migration stressors, coping strategies, and family, community, and institutional support. The questionnaire included the World Health Organization Composite International Diagnostic Interview module for post-traumatic stress disorder (PTSD). Interviews were translated, back-translated and administered b...

Postpartum depression in refugee and asylum-seeking women in Canada: A critical health psychology perspective

Canada has one of the world’s largest refugee resettlement programs in the world. Just over 48 percent of Canadian refugees are women, with many of them of childbearing age and pregnant. Refugee and asylum-seeking women in Canada face a five times greater risk of developing postpartum depression than Canadian-born women. Mainstream psychological approaches to postpartum depression emphasize individual-level risk factors (e.g. hormones, thoughts, emotions) and individualized treatments (e.g. psychotherapy, medication). This conceptualization is problematic when applied to refugee and asylum-seeking women because it fails to acknowledge the migrant experience and the unique set of circumstances from which these women have come. The present theoretical article explores some of the consequences of applying this psychiatric label to the distress experienced by refugee and asylum-seeking women and presents an alternative way of conceptualizing and alleviating this distress.

A realist review of family-based interventions for children of substance abusing parents

BackgroundMillions of children across North America and Europe live in families with alcohol or drug abusing parents. These children are at risk for a number of negative social, emotional and developmental outcomes, including an increased likelihood of developing a substance use disorder later in life. Family-based intervention programs for children with substance abusing parents can yield positive outcomes. This study is a realist review of evaluations of family-based interventions aimed at improving psychosocial outcomes for children of substance abusing parents (COSAPs). The primary objectives were to uncover patterns of contextual factors and mechanisms that generate program outcomes, and advance program theory in this field.MethodsRealist review methodology was chosen as the most appropriate method of systematic review because it is a theory-driven approach that seeks to explore mechanisms underlying program effectiveness (or lack thereof). A systematic and comprehensive search of academic and grey literature uncovered 32 documents spanning 7 different intervention programs. Data was extracted from the included documents using abstraction templates designed to code for contexts, mechanisms and outcomes of each program. Two candidate program theories of family addiction were used to guide data analysis: the family disease model and the family prevention model. Data analysis was undertaken by a research team using an iterative process of comparison and checking with original documents to determine patterns within the data.ResultsPrograms originating in both the family disease model and the family prevention model were uncovered, along with hybrid programs that successfully included components from each candidate program theory. Four demi-regularities were found to account for the effectiveness of programs included in this review: (1) opportunities for positive parent-child interactions, (2) supportive peer-to-peer relationships, (3) the power of knowledge, and (4) engaging hard to reach families using strategies that are responsive to socio-economic needs and matching services to client lived experience.ConclusionsThis review yielded new findings that had not otherwise been explored in COSAP program research and are discussed in order to help expand program theory. Implications for practice and evaluation are further discussed.

A realist review of brief interventions for alcohol misuse delivered in emergency departments

BackgroundBrief interventions (BIs) involve screening for alcohol misuse and providing feedback to patients about their use, with the aim of reducing alcohol consumption and related consequences. BIs have been implemented in various healthcare settings, including emergency departments (ED), where they have been found to contribute mixed results in their ability to address alcohol misuse among adults. Mechanisms through which BIs work and contextual factors impacting BI effectiveness are not clear. The purpose of this review was to understand how, for whom, and under what circumstances BIs work for adults misusing alcohol and who have been admitted to an ED. A realist review was chosen to answer these questions as realist reviews create context-mechanism-outcome configurations, leading to the development of comprehensive and detailed theories; in this case explaining how and for whom BIs work.MethodsDatabases including PsycINFO, Healthstar, CINAHL, Medline, and Nursing and Allied Health were searched for articles published until December 2013. The search strategy focused on studies examining BIs that targeted alcohol misuse among adults admitted into the ED. The search identified 145 relevant abstracts, of which 36 were included in the review. The literature was synthesized qualitatively (immersion/crystallization).ResultsFour mechanisms were found within reviewed studies, including engagement in/retention of BI materials, resolving ambivalence, increased awareness/insight into consequences of drinking, and increased self-efficacy/empowerment to use skills for change. The following contexts were found to impact mechanisms: emotional state, injury attributed to alcohol use, severity of alcohol use, and baseline stage of change.ConclusionsThis realist review provides advances in theories regarding which mechanisms to target during a BI and which contexts create the most favorable conditions for these mechanisms to occur, ultimately leading to optimal BI outcomes. These results can inform future clinical decision-making when delivering BIs in ED settings. Future research should conduct quantitative examination to confirm these findings.Systematic review registrationPROSPERO CRD42013006549.
