Relationships,Environment, and the Brain: How Emerging Research is Changing What We Know about the Impact of Families on Human Development

Recent research is providing family therapists with new information about the complex interaction between an individual's biological makeup and his/her social and physical environment. Family and social relationships, particularly during sensitive periods early in life, can affect a child's biological foundation. Additionally, stress during the early years can have a lasting effect on an individual's physical and mental health and contribute to the onset of severe mental illness. Community programs have been developed to intervene early with families who have an at‐risk child to prevent or minimize the onset of mental illness including providing partnerships with at‐risk mothers of infants to shape attachment relationships. Programs are also developing individual and family interventions to prevent the onset of psychosis. Practicing family therapists can incorporate emerging neuroscience and early intervention research and leverage the growing base of community programs to enhance the effectiveness and sustainability of mental health outcomes for clients. Additionally, family therapy education programs should broaden student training to incorporate the growing body of information about how family relationships affect individual mental health development.     

The Coping Paradox: Work,Stress, and Coping in the U.S. Army

The military environment has unique stressors. This study investigates the types of stressors, appraisals, and coping responses of U.S. soldiers and their leaders. A qualitative analysis of interviews indicates that the traditional coping buffers of social drinking and seeking social support from fellow soldiers, family, and leaders can potentially serve as sources of stress. While this paradox may be a result of the unique types of stressors in the military work environment, these results should direct researchers to better understand individuals' perceptions and appraisals of stress, with a focus on the meaning of stress, given contextual factors inherent in the workplace. The findings are discussed in relation to the literature on the impact of stress on physical and psychological health.     

Pathways to Lifespan Health Following Childhood Parental Death

The death of a parent is a profoundly stressful form of childhood adversity, increasing the short‐ and long‐term risk of mental health problems. Emerging research suggests it may also disrupt biological regulatory systems and increase the risk of long‐term physical health problems. This article presents a theoretical framework of the process by which the experience of parental death during childhood may influence mental and physical health outcomes over time. Drawing from a broad literature on adaptation following childhood parental loss, we focus on risk and protective factors in the childhood environment that are theoretically and empirically linked to emotional and biological regulatory responses to stress later in life, the effects of which may accumulate to impact long‐term health.     

Differential Effects of Family Stress Exposure and Harsh Parental Discipline on Child Social Competence

Low family socioeconomic status (SES) is a robust risk factor for adverse child outcomes, yet the specific processes that account for this risk are not fully understood. This study examines whether and how variation in two adverse factors, stressful life events and harsh parental discipline, affect children’s social competence within a high-risk environment, and whether some children are more vulnerable to these effects than others. Data were collected from 207 families of kindergarten children at risk for behavioral maladjustment. Children’s physiological regulation (respiratory sinus arrhythmia; RSA) measured during rest was examined as a moderator of risk exposure. Results indicate that both greater exposure to life stress and harsh discipline were correlated with lower social competence. Although children’s resting RSA was not a direct predictor of their social competence, it moderated the association between life stress and social competence. Greater exposure to life stress was more strongly associated with lower social competence among children with lower resting RSA. Higher RSA may help to buffer the effects of stress and facilitate appropriate social development. RSA did not moderate the effects of harsh discipline. This differential pattern of findings suggests that children’s physiological regulation can facilitate an effective response to situational stressors, but may be less efficacious in buffering against stress in the context of the parent-child relationship.     

Sexual Minority Stress and Social Support Explain the Association between Sexual Identity with Physical and Mental Health Problems among Young Lesbian and Bisexual Women

Bisexual women report more physical and psychological health problems than lesbian women do, which may be attributed to greater sexual minority stress and less social support. However, many studies combine lesbian and bisexual women into a single group. The current study examined if sexual minority stress and social support mediated the association between women’s sexual identity (lesbian or bisexual) and health-related outcomes. A total of 650 U.S. young adult lesbian (n?=?227) and bisexual (n?=?423) women completed an online survey about sexual minority stress, social support, and physical and mental health problems. Bisexual women reported more physical and mental health problems. A sequential mediation model showed that bisexual women reported greater sexual minority stress than lesbian women, which in turn was associated with less social support, which was associated with more physical and mental health problems. Greater sexual minority stress and lower social support may help explain why bisexual women report more health-related problems than lesbian women. The results of the present study support the importance of examining risk and protective factors for health problems separately for lesbian and bisexual women. Health-related intervention programs that target sexual minority women may need to be tailored differently for lesbian and bisexual women.

     

Stress, glucocorticoids and liquorice in human pregnancy: programmers of the offspring brain

A suboptimal prenatal environment may induce permanent changes in cells, organs and physiology that alter social, emotional and cognitive functioning, and increase the risk of cardiometabolic and mental disorders in subsequent life ("developmental programming"). Although animal studies have provided a wealth of data on programming and its mechanisms, including on the role of stress and its glucocorticoid mediators, empirical evidence of these mechanisms in humans is still scanty. We review the existing human evidence on the effects of prenatal maternal stress, anxiety and depression, glucocorticoids and intake of liquorice (which inhibits the placental barrier to maternal glucocorticoids) on offspring developmental outcomes including, for instance, alterations in psychophysiological and neurocognitive functioning and mental health. This work lays the foundations for biomarker discovery and affords opportunities for prevention and interventions to ameliorate adverse outcomes in humans.     

ROMANTIC PARTNERS' COPING STRATEGIES AND PATTERNS OF CORTISOL REACTIVITY AND RECOVERY IN RESPONSE TO RELATIONSHIP CONFLICT

Stress in close relationships can have significant negative consequences for mental health, physical health, and long-term relationship functioning. Dysregulated physiological responses to stress are potential pathways through which relationship stress may lead to these kinds of outcomes, and the ways in which individuals attempt to cope with relationship stress are likely to impact their physiological responses. However, our understanding of the specific coping strategies that predict physiological reactivity and recovery in these contexts is rather limited. This study explored relations between young adult college students' self-reported methods of coping with stress in their romantic relationships and their physiological reactivity to and recovery from negotiating conflict with their romantic partners. Partners' coping styles were also examined as predictors of physiological stress responses. One hundred and ninety opposite-sex couples (N = 380; modal length of relationship = 1-2 years) participated in an experimental conflict discussion task. Physiological stress reactivity to the task was assessed using salivary cortisol, a primary hormonal product of the hypothalamic-pituitary-adrenocortical (HPA) axis. Growth modeling of the cortisol levels before, during, and after the conflict task indicated that men who typically coped with relationship stress by seeking social support showed greater physiological reactivity to the conflict task. Partners' need for social support predicted stronger stress responses for both men and women, as well. While seeking social support is generally thought to be an adaptive coping strategy for couples, the results suggest that within the context of conflict negotiation in which receiving and providing support may be more difficult, seeking support from a partner is associated with greater phyisological stress.     

Weighed Down by Stigma: How Weight‐Based Social Identity Threat Contributes to Weight Gain and Poor Health

Weight stigma is pervasive, and a number of scholars argue that this profound stigma contributes to the negative effects of weight on psychological and physical health. Some lay individuals and health professionals assume that stigmatizing weight can actually motivate healthier behaviors and promote weight loss. However, as we review, weight stigma is consistently associated with poorer mental and physical health outcomes. In this article, we propose a social identity threat model elucidating how weight stigma contributes to weight gain and poorer mental and physical health among overweight individuals. We propose that weight‐based social identity threat increases physiological stress, undermines self‐regulation, compromises psychological health, and increases the motivation to avoid stigmatizing domains (e.g., the gym) and escape the stigma by engaging in unhealthy weight loss behaviors. Given the prevalence of overweight and obesity in the US, weight stigma thus has the potential to undermine the health and wellbeing of millions of Americans.     

Effects of voluntary wheel running on heart rate, body temperature, and locomotor activity in response to acute and repeated stressor exposures in rats

Stress often negatively impacts physical and mental health but it has been suggested that voluntary physical activity may benefit health by reducing some of the effects of stress. The present experiments tested whether voluntary exercise can reduce heart rate, core body temperature and locomotor activity responses to acute (novelty or loud noise) or repeated stress (loud noise). After 6 weeks of running-wheel access, rats exposed to a novel environment had reduced heart rate, core body temperature, and locomotor activity responses compared to rats housed under sedentary conditions. In contrast, none of these measures were different between exercised and sedentary rats following acute 30-min noise exposures, at either 85 or 98 dB. Following 10 weeks of running-wheel access, both groups displayed significant habituation of all these responses to 10 consecutive daily 30-min presentations of 98 dB noise stress. However, the extent of habituation of all three responses was significantly enhanced in exercised compared to sedentary animals on the last exposure to noise. These results suggest that in physically active animals, under some conditions, acute responses to stress exposure may be reduced, and response habituation to repeated stress may be enhanced, which ultimately may reduce the negative and cumulative impact of stress.     

Oxytocin and the emergence of individual differences in the social regulation of stress

The ability to use social support to regulate stress is critical to mental and physical health. Here, we posit that the oxytocin system contributes to the variability in individual responses to social support. We first review the evidence that oxytocin is related to both social functioning and stress regulation. We focus on results from molecular genetics suggesting that individual variations in both of these functions are associated with natural variations in the oxytocin receptor gene (OXTR). We then describe research that exploits this natural variation to directly and experimentally test relationships between the oxytocin system, social support, and stress regulation in both infants and adults. On the basis of our findings, we propose a novel theoretical model of how biological processes might interact with psychological beliefs about relationships—even in infants—to affect long‐term patterns of social regulation of stress.

STRESS AMONG PALESTINIAN WOMEN UNDER MILITARY OCCUPATION; WOMEN'S APPRAISAL OF STRESSORS,THEIR COPING MODES,AND THEIR MENTAL HEALTH

Psychological responses and mental health of 174 Palestinian women living in the occupied West-Bank and the Gaza Strip were studied through a stress model. Thirty-five Palestinian women living in Israel proper who had not been exposed to military occupation were interviewed as a comparison group. The stress process studied consists of women's appraisal of threat and the importance of the stressors in their lives, the estimation of their own resources to cope with stress, actual coping modes, and mental health outcomes. Women living under military occupation tended to appraise their environment as highly threatening and their experiences as strain-producing. At the same time they believed they had sufficient assets, especially collective and ideological resources, to deal with the stressors. This tendency was particularly evident among victims of political violence. Women strongly exposed to hardships of military occupation tended to employ more social and political activity and less inactive and accommodative coping modes than did less traumatized women. Exposure to stressful events, characteristic to military occupation and armed conflict, tended to deteriorate women's mental health, as indicated by severe anxiety, depression, hostile feelings and psychiatric symptoms, and also deteriorating their general health. Multiple regression analysis of the data pertaining to the stress process indicated not only the existence of objective stressors but also the appraisal of their harmfulness, the coping modes as well as vulnerability-protective factors which determine the outcomes of the stress process. A good economic situation, sufficient social support, and religious commitment functioned as protective factors in stress process, i.e., they were able to diminish the impact of exposure to stressors on women's mental health. In the case of the Palestinian women the hardships due to military occupation and national struggle initiated a different stress process than did the daily life difficulties. This indicates that in studies on psychological functioning in a political and armed conflict, the collective level of coping, values, norms, ideology as well as the concrete political aims of the society should be included in analysis and interpretation.     

Dorian Gray without his portrait: Psychological,social, and physical health costs associated with the Dark Triad

We examined how the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism) traits—as different social strategies—were associated with various health outcomes. In samples of American undergraduates (N = 1389), Australian high school students (N = 2023), and British undergraduates (N = 280), we examined the physical, social, and psychological costs associated with the Dark Triad traits. Narcissism was linked to few mental and physical ailments, suggesting it may provide a social buffer from negative health outcomes (Studies 1 and 2). Psychopathy (Studies 1 and 2) and Machiavellianism (Study 2) were linked to a number of psychological and physical health conditions. In addition, psychopathy was related to diminished life expectancy, whereas narcissism was related to enhanced life expectancy (Study 3). Our findings provide evidence that each of these personality traits is linked to various psychosocial tradeoffs and different methods of coping with stress and adaptive problems.     

Stress, appraisal, coping, and social support as predictors of adaptational outcome among dementia caregivers

A stress and coping model was used to study predictors of individual differences in caregiver adaptation. A total of 54 family caregivers of elderly dementia patients completed interviews and questionnaires assessing the severity of patient impairment and caregiving stressors; caregiver appraisals, coping responses, and social support and activity; and caregiver outcomes, including depression, life satisfaction, and self-rated health. Correlational and regression analyses supported the utility of the stress and coping model. Appraisal, coping responses, and social support and activity were significant predictors of caregiver outcome, even when severity of caregiving stressors was statistically controlled. The importance of a multidimensional approach to assessing caregiver outcomes was supported by regression analyses indicating that each caregiver outcome was predicted by different patterns of stressors, appraisal, coping, and social support and activity. Results are discussed in terms of a stress and coping model of caregiving, and clinical implications for work with caregiving families.     

Motives and Barriers for Physical Activity among Low-Income Black Single Mothers

Physical activity is associated with positive health outcomes, yet previous evidence suggests that single mothers, Black women, and those with low-income levels have low rates of physical activity. The purpose of the present study was to examine health status, as well as barriers and motives for physical activity, among low-income, Black single mothers from an intersectionality framework. Participants (n = 32) in this cross-sectional, mixed methods study completed questionnaires to assess physical activity, health status, stress, and barriers to physical activity and then participated in one of six focus groups to explore physical activity motives and barriers. Although participants reported many risk factors for disease including obesity, stress, and family disease history, most participants were not engaging in behaviors that would improve health such as regular leisure-time physical activity. Participants cited being a role model, stress relief, and weight loss as motives for physical activity that were connected to their social identities as low-income, Black single mothers. Chronic stress and stressors, responsibilities associated with single motherhood, and lack of social and community supports were described as barriers to physical activity. Future researchers and practitioners should consider these specific motives and barriers when designing interventions to increase physical activity among low-income, Black single mothers. We recommend that these programs focus on: promoting motives for physical activity that are meaningful and specific to this subpopulation of mothers, reducing stress, and enhancing affordable physical activity opportunities in the community for single mothers and their children.     

Mental and physical health of spouse caregivers: the role of personality.

Although personal resources of caregivers, such as coping skills and social support, have been shown to be important in understanding caregiver stress and health outcomes, personality traits have not previously been considered. The purpose of this study was to examine the association between the personality traits of neuroticism and dispositional optimism and mental and physical health outcomes. It was predicted that personality would have direct effects, and indirect effects through perceived stress, on health outcomes. Participants were spouse caregivers of patients diagnosed with Alzheimer's disease. Results showed that neuroticism and optimism were significantly related to mental and physical health. Furthermore, neuroticism had significant direct effects on all of the health outcomes, and substantial indirect effects, through perceived stress, on mental health outcomes. Optimism showed stronger indirect than direct effects on all health outcomes. These findings demonstrate the importance of including personality of the caregiver in theoretical and empirical models of the caregiving process.     

L’enfance et l’adolescence in situ : facteurs environnementaux facilitateurs et inhibiteurs de troubles cognitifs et comportementaux

The definition of mental health associates three fundamental variables: biological variables, psychological variables and environmental variables. In this article, we will focus on environmental variables that inhibit and facilitate cognitive and behavioural disorders in childhood and adolescence. Environmental psychology considers the interrelations between human and environment in its spatial, social and chronological dimensions and considers it as a characterized and undissociated system. We will bring to mind social and physical environmental variables with which children and adolescents interact frequently and, through a literature review, we will enlighten environmental variables that are susceptible to induce behavioural disorders and psychological variables that modulate children's and adolescent's relations to environment. We then suggest possible outcomes of this approach in clinical practice as well as in terms of therapeutic applications in child psychology and psychiatry. Finally, we evoke the necessity of taking in account neurobiological fields in order to outline a model of human development integrating the three variables that define mental health.     

Cultural Predictors of Physical and Mental Health Status among Mexican American Women: A Mediation Model

This study, using secondary data analysis, examined a mediation model of acculturation and ethnic pride as predictors of physical and mental health outcomes in a sample of 561 Mexican American women. Factors postulated as mediators were family support and religiosity. Systematic across-group comparison analyses were conducted to examine sources of differences in the mediation model between immigrant and non-immigrant women. The results partially supported the hypothesized mediation model, indicating that family support, but not religiosity, was a significant mediator in the relationship between ethnic pride and mental health problems. In addition, as differences between immigrant and non-immigrant women were observed only in the variables means, but not in the factor loadings or regression paths, the model tested may capture a common psychosocial process that affects these women and their health outcomes. Overall, this study offers important implications for future research and the design of intervention programs for Mexican American women.     

In the beginning: role of autonomy support on the motivation, mental health and intentions of participants entering an exercise referral scheme

Self-determination theory (Deci & Ryan, 2000, Intrinsic motivation and self-determination in human behaviour. New York: Plenum Publishing) highlights the impact autonomy supportive environments can have on exercise motivation and positive health outcomes. Yet little is known about whether differential effects occur as a function of which significant other is providing this support. Further, no research has examined the relationship between motivation and the social environment with participants' mental health and intentions to be physically active before entering an exercise intervention. Study participants were 347 British adults who were about to start an exercise referral scheme. Regression analyses revealed that the effects of autonomy support on mental health and physical activity intentions differed as a function of who provided the support (offspring, partner or physician), with the offspring having the weakest effects. A structural model was supported, indicating that autonomy support and more autonomous regulations led to more positive mental health outcomes and stronger intentions to be physically active. Knowledge of the social environmental and personal motivation of those about to commence an exercise programme can provide important insights for professionals supporting such efforts.     

Economic Disadvantage and Young Children’s Emotional and Behavioral Problems: Mechanisms of Risk

This study aimed to establish potential mechanisms through which economic disadvantage contributes to the development of young children’s internalizing and externalizing problems. Prospective data from fetal life to age 3 years were collected in a total of 2,169 families participating in the Generation R Study. The observed physical home environment, the provision of learning materials in the home, maternal depressive symptoms, parenting stress, and harsh disciplining practices were all analyzed as potential mediators of the association between economic disadvantage and children’s internalizing and externalizing problem scores. Findings from structural equation modeling showed that for both internalizing and externalizing problems, the mechanisms underlying the effect of economic disadvantage included maternal depressive symptoms, along with parenting stress and harsh disciplining. For internalizing but not for externalizing problem scores, the lack of provision of learning materials in the home was an additional mechanism explaining the effect of economic disadvantage. The current results suggest that interventions that focus solely on raising income levels may not adequately address problems in the family processes that emerge as a result of economic disadvantage. Policies to improve the mental health of mothers with young children but also their home environments are needed to change the economic gradient in child behavior.
