The psychosocial impact of Hurricane Katrina: contextual differences in psychological symptoms, social support, and discrimination

This study tested a contextual model of disaster reaction by examining regional differences in the psychosocial impact of Hurricane Katrina. A total of 386 individuals participated in this study. All were recruited in the primary areas affected by Hurricane Katrina and included residents of metropolitan New Orleans (Orleans Parish, Louisiana), Greater New Orleans (i.e., Metairie, Kenner, Gretna), and the Mississippi Gulf Coast (i.e., cities along the coast from Waveland to Ocean Springs, Mississippi). Participants were assessed for posttraumatic stress disorder (PTSD) symptoms, other psychological symptoms, perceptions of discrimination, perceptions of social support, evacuation distance, and the extent to which they experienced hurricane-related stressful events. Results were consistent with previous research on the impact of disasters on mental health symptoms. Findings extended research on individual differences in the response to trauma and indicated that regional context predicted unique variance in the experience of discrimination, social support, and emotional symptoms consistent with the theoretical model presented.     

Dynamic role of social support in the link between chronic stress and psychological distress.

How a chronic environmental stressor can interfere with the buffering effects of social support by eroding social support was analyzed in this prospective, longitudinal study. A classic buffering effect of support was found after 2 months of exposure to the stressor, household crowding. Crowded residents with low perceived support had greater increases in psychological distress than did crowded residents with high perceived support. However, after 8 months exposure the buffering effect disappeared. Moreover, greater crowding had become directly associated with lower support, which in turn was associated with greater increases in psychological distress. All analyses controlled for prior distress. Under some types of chronic stress, the buffering effects of social support may be short-lived because the stressor eventually erodes social support.     

Positive life events and social support and the relationship between life stress and psychological disorder

Conclusion In conclusion, the present research demonstrated the deleterious effects of negative life events. Number of negative events was a significant predictor of psychological disorder even when initial disorder was statistically controlled. The cross-sectional regression findings provided some support for the stress-buffering effects of positive life events, but these effects were nonsignificant when initial disorder was statistically controlled. The cross-sectional and prospective regression findings suggest that received social support, as measured by the ISSB, does not have a direct or stress-buffering effect on psychological disorder. These analyses, however, demonstrated the direct and stress-buffering effects of perceived social support, as measured by the ISEL, and the data suggest that the ISEL is a promising measure of this construct.The authors thank Sheldon Cohen who provided helpful comments on an earlier version of this article.     

Cultural differences in perceived social norms and social anxiety

Cultural considerations in social anxiety are a rarely investigated topic although it seems likely that differences between countries in social norms may relate to the extent of social anxiety. The present study investigated individuals' personal and perceived cultural norms and their relation to social anxiety and fear of blushing. A total of 909 participants from eight countries completed vignettes describing social situations and evaluated the social acceptability of the behavior of the main actor both from their own, personal perspective as well as from a cultural viewpoint. Personal and cultural norms showed somewhat different patterns in comparison between types of countries (individualistic/collectivistic). According to reported cultural norms, collectivistic countries were more accepting toward socially reticent and withdrawn behaviors than was the case in individualistic countries. In contrast, there was no difference between individualistic and collectivistic countries on individuals' personal perspectives regarding socially withdrawn behavior. Collectivistic countries also reported greater levels of social anxiety and more fear of blushing than individualistic countries. Significant positive relations occurred between the extent to which attention-avoiding behaviors are accepted in a culture and the level of social anxiety or fear of blushing symptoms. These results provide initial evidence that social anxiety may be related to different cultural norms across countries.     

Self-supporting personality and psychological symptoms: The mediating effects of stress and social support

This study examined relations among self-supporting personality, stress, social support, and psychological symptoms in a sample of 782 Chinese undergraduate students using the Self-Supporting Personality Scale for Adolescent Students (SSPS-AS), Adolescent Self-Rating Life Event Checklist (ASLEC), Multidimensional Scale of Perceived Social Support (MPSSS), and Symptoms Check List 90 (SCL-90). As predicted, results from cross-sectional structural equation analyses suggested that stress and social support mediate the relationship between four self-supporting personality traits and psychological symptoms; an alternative stress-moderation model was not supported.     

Individual differences in the impact of attentional bias training on cardiovascular responses to stress in women

Abstract

Experimental studies show that training people to attend to negative stimuli makes them more likely to respond with greater anxiety to stress. The present study investigated this effect in students using measures of cardiovascular responses to stress and examined whether individual differences influence the impact of attention training on stress responses. Using a standard dot probe task, 30 participants underwent negative attentional bias training and 34 participants underwent anti-negative training before completing a stressful speech task. Results indicated that, overall, participants exhibited acclimatization to the procedures (indicated by a dip in blood pressure post-training) and normal stress responding (indicated by elevated blood pressure in response to stress; p<.001). However, consideration of participants’ scores for neuroticism/emotional-stability revealed important differences in how the intervention impacted on cardiovascular profiles (p=.008). For participants with high neuroticism scores, the negative attentional bias intervention elicited more exaggerated stress responding than the anti-negative intervention. For those with low neuroticism scores (i.e., emotionally stable participants), the anti-negative intervention was associated with elevated post-intervention blood pressure and higher blood pressure reactivity to stress. These findings provide evidence of the impact of attentional bias manipulation on physiological stress reactivity and suggest the effect is highly contingent on individual temperaments.

The impact of daily stress on health and mood: psychological and social resources as mediators

This study examined daily stress processes among 75 married couples across 20 assessments during a 6-month period. The somatic and psychological effects of common everyday hassles were investigated. Overall, there was a significant relationship between daily stress and the occurrence of both concurrent and subsequent health problems such as flu, sore throat, headaches, and backaches. The relationship of daily stress to mood disturbance was more complex. The negative effects of stress on mood were limited to a single day, with the following day characterized by mood scores that were better than usual. Furthermore, striking individual differences were found in the extent to which daily stress was associated with health and mood across time. Participants with unsupportive social relationships and low self-esteem were more likely to experience an increase in psychological and somatic problems both on and following stressful days than were participants high in self-esteem and social support. These data suggest that persons with low psychosocial resources are vulnerable to illness and mood disturbance when their stress levels increase, even if they generally have little stress in their lives.     

Gender differences in social support and physical health

A large body of prospective data has accumulated linking social support to health, and most social scientists agree that low levels of support are associated with poor physical and mental health. Unfortunately, most of the research has been limited to White men. When women and people of color are included in the designs, the relationships between social support and physical health are more complicated. Prospective population-based studies provide evidence that low support is associated with increased risk of mortality in women. However, in several studies, results indicated that, for specific age groups, women with high social support have increased risk of mortality. Factors that may contribute to the observed gender differences in the social support-physical health relationship are discussed. Future research should include adequate numbers of women and more sophisticated measures of social support to move the field forward.     

Structural gender differences in perceived social support

Gender is an important influence on support-relevant social interactions, however findings of studies on gender differences in social support are not definitive. Although differences between men and women in the various social support measures have been found in numerous studies, neither the cause nor the explanatory process is known. This study examines gender differences in the dimensionality of social support. A large sample (N=3210) from the general population of women (60%) and men aged between 18 and 65 years old (Mean AGE=34.1) responded to a brief scale with items assessing the distinct functions of the perceived availability of social support. Confirmatory factor analyses yielded one factor in the women's sample that measures global social support perceived, and two in the men's. The first factor in the men's sample measures emotional support (providing empathy, caring, validation of self-worth), and the second measures instrumental support (e.g. practical assistance or financial aid). We concluded that there are gender differences in the structure of perceived social support and that these differences can be explained by socialization experiences and social roles associated with gender.     

Race,psychosocial vulnerability and social support differences in inner-city women's symptoms of posttraumatic stress disorder

Background/Objectives: Inner-city Black women may be more susceptible to posttraumatic stress disorder (PTSD) than White women, although mechanisms underlying this association are unclear. Living in urban neighborhoods distinguished by higher chronic stress may contribute to racial differences in women's cognitive, affective, and social vulnerabilities, leading to greater trauma-related distress including PTSD. Yet social support could buffer the negative effects of psychosocial vulnerabilities on women's health. Methods/Design: Mediation and moderated mediation models were tested with 371 inner-city women, including psychosocial vulnerability (i.e., catastrophizing, anger, social undermining) mediating the pathway between race and PTSD, and social support moderating psychosocial vulnerability and PTSD. Results: Despite comparable rates of trauma, Black women reported higher vulnerability and PTSD symptoms, and lower support compared to White Hispanic and non-Hispanic women. Psychosocial vulnerability mediated the pathway between race and PTSD, and social support moderated vulnerability, reducing negative effects on PTSD. When examining associations by race, the moderation effect remained significant for Black women only. Conclusions: Altogether these psychosocial vulnerabilities represent one potential mechanism explaining Black women's greater risk of PTSD, although cumulative psychosocial vulnerability may be buffered by social support. Despite higher support, inner-city White women's psychosocial vulnerability may actually outweigh support's benefits for reducing trauma-related distress.     

Individual differences in the phenomenological impact of social stigma

In an attempt to define stigmatization from the perspective of stigmatized group members, the author focused on the development and validation of a stigmatization scale. The scale's content validity was established with the assistance of experts in the field. European American, African American, and Native American students from 5 different U.S. universities completed the Stigmatization Scale. The construct validity of the scale was suggested by its convergence with similar measures of social alienation and its divergence from measures of personal subjective well-being. The finding that both the African American and Native American students reported significantly higher stigmatization scores than did the European Americans indicated the scale's known-groups validity. African American students at a predominantly Black university reported lower stigmatization than did African American students at a predominantly White university, suggesting the scale's malleability to context.     

Gender and sex role differences in the perception of social support

This study examined the relationships among support types (i.e., emotional, instrumental, and nonintimate social participation), gender, sex role orientation, and stress level among college undergraduates (N=253). Dependent variables included need, perceived availability, and satisfaction with support. Sex differences were found only in emotional support, with men reporting less need, perceived availability, and marginally less satisfaction than women. The only gender by sex role interaction was on need for emotional support. Traditional sex-typed men reported less need than traditional women, whereas there was no difference between androgynous men and women. While sex differences do exist for emotional support, the effects of sex role orientation on perceptions of social support appears to be somewhat circumscribed.     

Exploring age differences in the stress-buffering function of social support

The purpose of this study is to see if there are age differences in the relationship between chronic financial strain, emotional support, and life satisfaction among people aged 65 and older. Data from a nationwide survey of older people (N = 1,518) indicate that emotional support tends to reduce the noxious effects of economic problems on life satisfaction for the sample as a whole. However, the findings further reveal that the potential benefits of emotional support arise primarily among the oldest-old. In contrast, emotional support does not offset the negative effects of financial strain on life satisfaction among the young-old.     

Gender differences in cardiovascular and hypothalamic-pituitary-adrenal axis responses to psychological stress in healthy older adult men and women

Gender differences in the neuroendocrine and cardiovascular response to psychological stress may contribute to the gender differences in the prevalence of diseases associated with hypothalamic-pituitary-adrenal (HPA) axis reactivity such as cardiovascular disease (CVD), diabetes and hypertension. We measured plasma ACTH, cortisol, heart rate (HR), and blood pressure (BP) responses in 8 men and 8 women (55-75 years) exposed to the Matt Stress Reactivity Protocol (MSRP), a psychological challenge. The MSRP elicited significant increases in HR, systolic-, and diastolic BP, ACTH and cortisol (all p<0.01). Men had significantly greater cortisol and diastolic BP responses compared to women (p<0.05). Additionally, a positive correlation between the ACTH and cortisol responses was only found in the males (r=0.71, p<0.05). There were no group differences in HR, systolic BP, or ACTH responses. We conclude, that among older adults, men respond to psychological stress with greater increases in cortisol, compared to women. This greater activation of the HPA axis could translate into an elevated risk for CVD, diabetes and hypertension and may be related to the higher prevalence of these diseases in males. Gender differences in brain structures and/or cognitive processes may be responsible for these sexually dimorphic stress responses.     

Spirituality and psychological pain: the mediating role of social support

Spirituality is a multifaceted construct, and often studied as a one- or two-dimensional variable. Recent work has resulted in the development of the RiTE model of spirituality. While preliminarily supported as a useful approach to measuring spirituality, little is known regarding its associations with other outcomes. Past studies have shown inverse associations between spirituality and psychological distress, which appears to be partially a function of social support derived from spiritual beliefs or practices. As such, the present study tested the relationship between the RiTE dimensions and psychache as mediated by multiple types of social support. Parallel mediation results from an undergraduate sample (N?=?1994) showed that all three RiTE dimensions were indirectly associated with psychache via multiple forms of social support. Ritualistic and existential spirituality also displayed direct associations with psychache. Implications of these findings are discussed in the context of past literature, applicable theoretical constructs, and treatment considerations.     

The role of neuroticism on psychological and physiological stress responses

This study examined the influence of personality on stressor appraisals and emotional, physiological, and behavioral responses to psychosocial stress. Appraisals were used to classify participants as threatened (they believed their coping resources were inadequate relative to stressor demands) or challenged (they believed their coping resources were commensurate with stressor demands). Neuroticism predicted threat appraisals, and both were related to negative emotional experience and poor task performance. The influence of neuroticism on negative emotions and poor performance was mediated by threat appraisals. High neuroticism confers stress vulnerability, but only when conditions are construed as threatening.     

Gender differences in social support among older adults

The purpose of this study was to determine whether exposure to life stress can help explain gender differences in the use of social support. Findings from a longitudinal study suggest that as the number of stressful life events increase, elderly men and women are equally likely to become more involved in their social network, while gender differences emerge only in response to chronic financial strain. Further analysis indicates that elderly women are more likely than elderly men to report that the support they received increased their feelings of personal control.
