Positive Events and Social Supports as Buffers of Life Change Stress1

A perceived availability of social support measure (the ISEL) was designed with independent subscales measuring four separate support functions. In a sample of college students, both perceived availability of social support and number of positive events moderated the relationship between negative life stress and depressive and physical symptomatology. In the case of depressive symptoms, the data fit a “buffering” hypothesis pattern, i.e., they suggest that both social support and positive events protect one from the pathogenic effects of high levels of life stress but are relatively unimportant for those with low levels of stress. In the case of physical symptoms, the data only partially support the buffering hypothesis. Particularly, the data suggest that both social support and positive events protect one from the pathogenic effects of high levels of stress but harm those (i.e., are associated with increased symptomatology) with low levels of stress. Further analyses suggest that self-esteem and appraisal support were primarily responsible for the reported interactions between negative life stress and social support. In contrast, frequency of past social support was not an effective life stress buffer in either the case of depressive or physical symptomatology. Moreover, past support frequency was positively related to physical symptoms and unrelated to depressive symptoms, while perceived availability of support was negatively related to depressive symptoms and unrelated to physical symptoms.     

The relationship of work stressors and emotional support to strain in police officers

This study tested whether quantity and quality of social support and two sources of work stress (organizational stressors and job risk) predicted work strain in police officers, a high-risk occupational group. The participants were 135 police officers from a large metropolitan law enforcement agency who responded to questionnaires for assessing work stress, social support, exhaustion, and other strain symptoms. Emotional support and work stressors accounted directly for significant variance in emotional exhaustion, depersonalization, and symptom frequency. Conflicted relationships, which are a source of both work stress and support, also contributed to strain. In contrast to previous findings, a reverse buffering effect for social support did not contribute to predicting strain. Stress management programs for police and other high-stress occupations should target increasing emotional support from supervisors and peers, and reducing conflict in job and family relationships.

采用网络受欺负量表、压力感量表、网络社会支持问卷和流调中心用抑郁量表对751名初中生进行调查,考察了青少年网络受欺负与抑郁的关系、压力感在网络受欺负与抑郁间的中介作用以及网络社会支持在其中的调节作用。结果表明：（1）青少年网络受欺负与抑郁存在显著正相关;（2）压力感在网络受欺负和抑郁间起完全中介作用;（3）网络社会支持在网络受欺负事件引起的压力感与抑郁间起调节作用,压力感对青少年抑郁的影响,随网络社会支持水平的提高而降低。     

Social Support in Academic Programs and Family Environments: Sex Differences and Role Conflicts for Graduate Students

We hoped to identify the sources and types of social support that are most beneficial for helping graduate students cope with stress. A second purpose of our study was to identify sex differences in stress and the most beneficial types of support. Students living in graduate student housing were surveyed to assess (a) social support in their academic programs and in their family environments, (b) recent stressful life events, and (c) depression and anxiety as psychological symptoms of stress. Women reported significantly more stress, more symptoms of stress, and significantly less support from their academic departments and family environments than did men. Family support had only buffering effects, but no direct effects on stress symptoms for women. Graduate program and family support had direct effects, but no buffering effects on stress symptoms for men. These results may indicate greater role strain for women, perhaps resulting from less support for their multiple roles and greater concerns about balancing academic and family demands.     

Social Support,Conflict, and Integration Among Women Living With HIV/AIDS1

The relationship between depressive symptoms and perceptions of available social support, social conflict, and subjective social integration were examined as part of a psychosocial study of Puerto Rican, African American, and non‐Hispanic White women living with HIV/AIDS (N= 146) in New York City. Lower levels of subjective social integration and higher levels of social conflict were associated with more depressive symptoms. Perceived availability of social support was not significantly associated with depression in comparison with these other forms of support. No evidence was found for a stress‐buffering or a stress‐amplification effect. Significant ethnic differences in levels of social integration and social conflict also were noted. Results suggest that intervention efforts should go beyond addressing support to further address the conflict and lack, of integration experienced.     

Social support and adaptation to stress by the elderly

The first of a two-phase project is reported that examined the prospective effects of stress and social support on the physical and mental health of the elderly. A sample of 50 elderly subjects was assessed at two points in time over a 6-month period. Results indicated that social support was a significant predictor of physical health status, whereas mental health was related to the Stress X Social Support interaction term. These latter results were consistent with the buffering hypothesis, in that high levels of social support served to reduce the negative impact of stress on mental health. Individuals who were in better mental health at the initial assessment experienced fewer stressful events and higher levels of social support over the subsequent 6-month period. The implications of these findings for research and theory regarding the relation between stress and social support are discussed.     

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.     

Depressive Symptoms Among Delinquent Youth: Testing Models of Association with Stress and Support

The high prevalence of depression among incarcerated youth indicates a need to better understand factors that contribute to depression within this vulnerable subgroup. Previous research in general community samples has suggested that high levels of stress and low levels of parental support are associated with depression in young people, but it is unclear whether or how they might be associated with depression among incarcerated youth who are already vulnerable. Using a sample of 228 adolescents (aged 13–18 years) who were detained in the juvenile justice system, stress and support were modeled as independent main effects and as interactive risk factors in relation to depressive symptoms. More stressful life events and less caregiver support were each independently associated with depressive symptoms, but no evidence was found for the buffering hypothesis in this sample. Stressful life events were more strongly associated with depressive symptoms among boys compared to girls.     

Influences of stress and situation-specific mastery beliefs and satisfaction with social support on well-being and academic performance.

The present study examined the effects of stress and cumulative situation-specific mastery beliefs and satisfaction with social support on somatic and psychological symptomatology and academic performance of 146 college men. Stress was directly related to increased symptomatology and decreased grade point average, whereas mastery beliefs were directly associated with reduced depression and anxiety. Satisfaction with social support was related to anxiety through an interaction with mastery. Neither mastery nor satisfaction with support appeared to act as a stress-buffer through a statistical interaction with stress to moderate effects of high stress. However, earlier analysis of some of the same data showed that total stress, the best predictor of each outcome in this study, was reduced by the combination of strong situation-specific mastery beliefs and high satisfaction with support for subjects who faced many stressors. The combined findings show that situation-specific mastery beliefs reduced appraisal of stress and were associated with better psychological adjustment.     

A structural modeling approach to the understanding of parenting stress

Tested and cross-validated a multidimensional model of predictors of parenting stress on data from a population-based sample of Swedish mothers (N = 1,081) with children ages 6 months to 3 years. The study was a cross-sectional questionnaire study, focusing on the explanation of variance in parenting stress. Structural equation modeling procedures permitted disentanglement of total, direct, and indirect effects. A Swedish instrument based on parts of the Parent Domain in the Parenting Stress Index was used as a measure of stress. The results provided general support for the proposed model. High workload, low social support, perception of the child as fussy-difficult, negative life events, child caretaking hassles, more children in the family, and high maternal age related directly to more stress. Child irregularity contributed indirectly to mother's experienced stress. No buffering effects of social support were found. Forty-eight percent of the variance in the parenting stress measure was explained by the model. Implications for interventions were discussed.     

A preliminary study of the moderating role of church-based social support in the relationship between racist experiences and general anxiety symptoms

The current study explores the potential buffering effect of church-based social support on the effect of racism on anxiety symptomology in a Black sample. Fifty participants completed a questionnaire packet containing measures of anxious arousal and stress (general anxiety) symptoms, church-based social support, and experience of racist events. Results indicated that church-based social support moderated the relationship between racist experiences and general anxiety symptoms such that at low levels of church-based social support the experiences of racism and stress (general anxiety) symptoms were significantly positively associated. The clinical implications of these findings and future research directions are discussed.     

Divorcing mothers and social support: Testing the specificity of buffering effects

The circumstances under which social support buffers the negative effects of stress have been a subject of much research. The hypothesis that social support is effective only when it matches the needs elicited by particular stressors was studied in a sample of divorcing mothers. Predictions were made regarding which types of support (Parenting, Emotional, and Tangible) would buffer the effects of Parenting, Social, and Tangible stress on depressive symptoms and on general psychological distress of divorcing mothers. Results did not support the specificity of social support buffering effects, though the stress and support scales often showed direct relationships to criterion measures. Implications were discussed for the assessment of support with multiple models, for future research designs, and for planning prevention programs to meet the needs of divorcing mothers.     

The Relational Context of Social Support in Young Adults: Links with Stress and Well-Being

This study examined the roles of relationship-specific social support and gender in the associations between perceived stress and well-being. Three sources of support (family, friends, and romantic partners) and three well-being indicators (loneliness, depressive symptoms, and physical health) were assessed in 628 young adults attending college (M _age = 19.72; range of 18–24). Stress directly predicted all well-being indicators, and indirectly predicted well-being through social support in relationship-specific ways. Family support mediated the relationship between stress and physical health, friend support mediated the association between stress and loneliness, and romantic partner support mediated the relationships of stress with both loneliness and depressive symptoms. With regard to loneliness and physical health, women were more strongly impacted when they had less support from friends.     

Depressive Symptomatology among HIV-Positive Women in the Era of HAART: A Stress and Coping Model

Objective: An enhanced stress and coping model was used to explain depression among HIV-positive women in healthcare and community settings where highly active anti-retroviral treatment (HAART) was commonplace. Method: HIV-infected women in four cities (N=978) were assessed, cross-sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self-reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self-efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self-efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self-efficacy, bolstering social supports, and decreasing stress in the lives of HIV-positive women may help to reduce the negative effects of HIV disease on mood.     

Acculturative stress, social support, and coping: relations to psychological adjustment among Mexican American college students

This study examined the relations between acculturative stress and psychological functioning, as well as the protective role of social support and coping style, in a sample of 148 Mexican American college students (67% female, 33% male; mean age = 23.05 years, SD = 3.33). In bivariate analyses, acculturative stress was associated with higher levels of anxiety and depressive symptoms. Moreover, active coping was associated with better adjustment (lower depression), whereas avoidant coping predicted poorer adjustment (higher levels of depression and anxiety). Tests of interaction effects indicated that parental support and active coping buffered the effects of high acculturative stress on anxiety symptoms and depressive symptoms. In addition, peer support moderated the relation between acculturative stress and anxiety symptoms. Implications for reducing the effects of acculturative stress among Mexican American college students are discussed.     

Assessment of stress-buffering effects of social networks on psychological symptoms in an inner-city elderly population

Social network researchers have been divided into two camps: those who propose that social networks have a direct effect on subsequent psychological symptoms and those who posit a stress-buffering effect as well. Previous research has been limited by rudimentary measures of social interaction and the absence of longitudinal data as well as by different approaches to the assessment of possible buffering effects. In the present study, using 19 social network variables, the authors followed 133 elderly residents of mid-Manhattan SRO hotels for 1 year. Three different methods of determining buffering effects were examined: Dividing the sample into high- and low-stress groups and contrasting differences in percentage variance accounted for by social networks between the two groups; Examining the group as a whole to assess if any Network Variable X Stress interactional terms are significant; Examining the group as a whole to assess whether there is a reduction in the beta value of stress with respect to psychological symptoms when network variables are added to the analysis. Method 1 indicated a direct network effect, but none of the methods indicated a buffering effect. Of clinical relevance was the nonlinearity of the network effects, that is, depending upon a person's stressor level, different network dimensions must be emphasized and strengthened.     

Perfectionism,Components of Stress Reactivity,and Depressive Symptoms

The current study examined the associations among dimensions of perfectionism, facets of stress reactivity, and self-reported depressive symptoms in 191 university students. Participants completed the Multidimensional Perfectionism Scale, the Perfectionism Cognitions Inventory, the Perceived Stress Reactivity Scale (PSRS), and a measure of depressive symptoms. The PSRS is a relatively new instrument that measures several distinguishable facets of stress reactivity including prolonged stress reactivity, reactivity to failure, and reactivity to social evaluation. Analyses confirmed that most of the perfectionism measures were associated with stress reactivity to failure experiences. Socially prescribed perfectionism and perfectionistic automatic thoughts were also associated with prolonged stress reactivity and reactivity to social evaluation. Moreover, all facets of stress reactivity were correlated with depressive symptoms. Finally, prolonged stress reactivity and reactivity to social evaluation mediated the links between perfectionism dimensions and depressive symptoms. The current findings provide general support for models of perfectionism and stress, and suggest that perfectionists have heightened sensitivities to stressors related to their self-definitions that are activated when threatening stressors involving these themes are experienced.     

The Impact of Child Symptom Severity on Stress Among Parents of Children with ASD: The Moderating Role of Coping Styles

We examined the impact of autism severity and parental coping strategies on stress in parents of children with ASD. Children’s autism symptoms and parental coping strategies (task-oriented, emotion-oriented, social diversion, and distraction) were evaluated as predictors of four types of parental stress (parent and family problems, pessimism, child characteristics, and physical incapacity). In order to examine potential buffering effects of coping strategies on stress associated with the child’s symptom severity, the interactive effects of autism symptoms with coping strategies were also examined. Participants included 77 primary caregivers of a child with ASD. Using multiple regression analyses, emotion-oriented coping scores were associated with more parent and family problems, and task-oriented coping was associated with lower physical incapacity scores. The child’s autism severity was the strongest and most consistent predictor of stress. Further, emotion-oriented coping moderated the relationship between pessimism stress and autism symptomatology, and distraction coping was a moderator between parent and family stress and autism symptoms. Results indicate that increasing our knowledge of the coping strategies that are more or less effective and under what conditions some coping strategies may be either beneficial or harmful for this population of parents has direct implications for treatment and parent education efforts.     

Coping with a threat to life: A longitudinal study of self-concept,social support,and psychological distress

The relationship of self-concept (self-esteem and mastery) and social support to psychological distress was studied among 68 Israeli women immediately prior to undergoing biopsy for suspected cancer (acute stress) and 3 months later for the noncancer group (everyday stress). It was predicted that women with stronger self-concepts and more social support would experience less state depression and state anxiety during the acute crisis than women with weaker self-concepts and less social support. It was further predicted that self-concept would be more critical than social support due to the acute nature of the event. Finally, self-concept was predicted to be related to psychological distress both during the acute and everyday stress situations (a direct effect), while social support was predicted to be related to psychological distress only during the acute stress situation (a buffering effect). The hypotheses were generally confirmed. However, self-concept and social support were seen as complexly related to psychological distress during the acute phase, one not necessarily being more critical than the other. The selective employment of available resistance resources to fit the situation and implications for preventive intervention were discussed.     

The Roles of Social Support and Self-Efficacy in Physical Health’s Impact on Depressive and Anxiety Symptoms in Older Adults

Physical illness may precipitate psychological distress among older adults. This study examines whether social support and self-efficacy moderate the associations between physical health and depression and anxiety. Predictions were tested in 222 individuals age 60 or older presenting for help with worry. Physical health was assessed through self-report (subjective) and physical diagnoses (objective). Objective physical health did not have a significant association with depression or anxiety. Worse subjective physical health was associated with increased somatic anxiety, but not with depression or worry. The relationship between subjective physical health and depressive symptoms was moderated by self-efficacy and social support. As predicted, when self-efficacy was low, physical health had its strongest negative association with depressive symptoms such that as physical health improved, depressive symptoms also improved. However, the moderation effect was not as expected for social support; at high levels of social support, worse physical health was associated with increased depressive affect.
