The influence of social support and perceived stress on response time inconsistency

Objectives: Lack of social support and high levels of stress represent potentially modifiable risk factors for cognitive aging. In this study we examined the relationships between these two risk factors and response time inconsistency (RTI), or trial-to-trial variability in choice response time tasks. RTI is an early indicator of declining cognitive health, and examining the influence of modifiable psychosocial risk factors on RTI is important for understanding and promoting cognitive health during adulthood and old age.

Methods: Using data from a community sample study (n = 317; M_age = 49, range = 19–83), we examined the effects of social support, including size of network and satisfaction with support, global perceived stress, and their interactions on RTI.

Results: Neither size of network nor satisfaction with support was associated with RTI independent of perceived stress. Stress was positively associated with increased RTI on all tasks, independent of social support. Perceived stress did not interact with either dimension of social support to predict RTI, and perceived stress effects were invariant across age and sex.

Conclusion: Perceived stress, but not social support, may be a unique and modifiable risk factor for normal and pathological cognitive aging. Discussion focuses on the importance of perceived stress and its impact on RTI in supporting cognitive health in adulthood and old age.     

The relationship between parental stress and mastery,forgiveness, and social support among parents of children with autism

BackgroundParents of children with autism have significantly more parenting-stress symptoms than parents of typically developing children. Therefore, the main goal of the present study was to examine the relationship between personal and social resources among families of different cultures, in which parents are coping with the stress of raising children with autism.MethodTwo hundred and nine (N = 209) participants, including Jewish (n = 105) and Arab (n = 104) participants, completed demographic, mastery, forgiveness, social support, and parental stress questionnaires.ResultsThe study findings demonstrated no significant differences between the groups regarding mastery, forgiveness, or social support. However, a marginally significant difference was found with regard to the age at the time of diagnosis and parental stress. Arab children were diagnosed earlier and Arab parents reported higher levels of parental stress. Hierarchical multiple regressions showed that among the Jewish sample age, education, financial situation, mastery, and social support contributed significantly to the explained variance in parental stress. Among the Arab sample, severity of autism, forgiveness, mastery, and social support contributed significantly to the explained variance in parental stress.ConclusionsThese findings make an important contribution to our understanding of mastery, forgiveness, and social support while helping parents cope with the stress of raising a child with autism. In addition, in multicultural countries, it is important to be aware of differences and similarities in the factors predicting parental stress.     

Judicial stress: the roles of gender and social support

Because judges experience a myriad of occupational stressors, they are at risk of experiencing secondary trauma, burnout, negative mental/physical health, poor job performance and low job satisfaction. These experiences might not be uniform, however, as gender and social support might mitigate such stress-related outcomes. Judges from two states in the United States completed a variety of stress and subjective performance measures. Social support was related to less perceived stress, less burnout, and more job satisfaction, but only for males. This suggests that males and females might receive qualitatively different types of social support. Different types of social support could differ in their ability to buffer judges from these stress-related outcomes. Further, among judges with high social support, females scored higher than males on subjective job performance; the opposite pattern occurred for judges with low social support. Thus, a lack of social support appears to have a negative effect on performance self-appraisals but only for females. Results have implications for the psychological study of stress and for programs designed to reduce judges’ stress.     

The ties that bind: perceived social support,stress, and IBS in severely affected patients

Background This study assessed the association between social support and the severity of irritable bowel syndrome (IBS) symptoms in a sample of severely affected IBS patients recruited to an NIH‐funded clinical trial. In addition, we examined if the effects of social support on IBS pain are mediated through the effects on stress. Methods Subjects were 105 Rome II diagnosed IBS patients (F = 85%) who completed seven questionnaires which were collected as part of a pretreatment baseline assessment. Key Results Partial correlations were conducted to clarify the relationships between social support and clinically relevant variables with baseline levels of psychopathology, holding constant number of comorbid medical diseases, age, gender, marital status, ethnicity, and education. Analyses indicated that social support was inversely related to IBS symptom severity. Social support was positively related with less severe pain. A similar pattern of data was found for perceived stress but not quality of life impairment. Regression analyses examined if the effects of social support on pain are mediated by stress. The effects of social support on bodily pain were mediated by stress such that the greater the social support the less stress and the less pain. This effect did not hold for symptom severity, quality of life, or psychological distress. Conclusions & Inferences This study links the perceived adequacy of social support to the global severity of symptoms of IBS and its cardinal symptom (pain). It also suggests that the mechanism by which social support alleviates pain is through a reduction in stress levels.     

Maternal stress and social support prospectively predict infant inflammation

Maternal stress has been suggested to be a risk factor for offspring health, while social support has been shown to be a protective factor for offspring functioning. Currently, research has yet to investigate how both of these factors may relate to infant inflammatory processes and associated biological aging in the first years of life. In 48 mother-infant dyads, we investigated whether maternal parenting stress and social support when infants were 12 and 18 months of age were cross-sectionally associated with infant salivary C-reactive protein (sCRP) during these times. In addition, we investigated whether parenting stress and social support were prospectively associated with later sCRP and changes in sCRP from 12 to 18 months of age, as well as whether those changes in sCRP were associated with subsequent infant salivary telomere length (sTL), a marker of biological aging. Analyses revealed that while there were no cross-sectional associations between maternal factors and infant sCRP, maternal parenting stress and social support when infants were 12 months of age predicted infant sCRP at 18 months of age. Further, maternal social support predicted changes in infant sCRP from 12 to 18 months of age. We observed a null association between infant sCRP and sTL. Implications for the ways that maternal mental health and social support may impact biological mechanisms related to disease processes in infants are discussed.     

Understanding the relationship of perceived social support to post-trauma cognitions and posttraumatic stress disorder

Poor social support in the aftermath of a traumatic event is a well-established risk factor for posttraumatic stress disorder (PTSD) among adult trauma survivors. Yet, a great deal about the relationship between social support and PTSD remains poorly understood. In this study, we analyzed data from 102 survivors of a serious motor vehicle accident (MVA) at 4 weeks (Time 1) and 16 weeks (Time 2) post-MVA. We assessed the role of perceived dyadic social support, positive dyadic interaction, and negative dyadic interaction in the development and maintenance of PTSD. In addition, we examined how these social support constructs work together with negative post-trauma cognitions to affect the maintenance of PTSD. Neither perceived social support nor the quality of social interaction (i.e., positive or negative) was associated with PTSD symptom severity at Time 1. However, among those with elevated PTSD symptom severity at Time 1, greater social support and positive social interaction and lower negative social interaction were each associated with reductions in PTSD symptom severity from Time 1 to Time 2. For social support and negative social interaction, this association ceased to be significant when jointly assessed with negative post-trauma cognitions, suggesting that perceived social support and negative dyadic interaction were associated with maintenance of PTSD symptom severity because of their association with negative post-trauma cognitions. These results provide support to models and treatments of PTSD that emphasize the role of negative post-trauma cognitions in maintenance of PTSD.     

The differential relationships of dimensions of perceived social support with cognitive function among older adults

Objectives: Research has extensively examined the relationship of social support and cognition. Theories on social support suggest that it is a multidimensional construct including perceptions, actual assistance, and level of integration into a social network. Little is known, however, about the differential associations between distinct dimensions of perceived social support and cognition. This study examined whether four empirically validated dimensions of perceived social support were differentially related to cognitive function in aging, and whether this association was moderated by gender.

Methods: The sample included 355 community-residing older adults (mean age = 77 years; %female = 55) enrolled in a longitudinal cohort study. Social support was assessed using the Medical Outcomes Study-Social Support Survey. Cognition was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

Results: Principal component analysis yielded four factors capturing different dimensions of social support: emotional/informational support, positive social interaction, tangible support, and affectionate support. Linear regression analyses revealed that both perceived emotional/informational support (beta = 1.41, p = 0.03; 95% Confidence Interval (CI) = .156–2.669) and positive social interaction (beta = 1.71, p = 0.01; 95% CI = .428–2.988) were significantly associated with RBANS total index score. Further analyses revealed that gender moderated the relationship between emotional/informational support (beta = 1.266, p = 0.04), demonstrating that higher levels of perceived emotional support were associated with higher index scores in females but not in males.

Discussion: The associations between perceived emotional/informational support and positive social interaction suggest that social engagement may be an important target for intervention procedures for individuals at risk of cognitive decline and dementia.     

Stressors social support and elder mistreatment

Objectives: This study sought to examine the pathways through which interpersonal relationship strain and loneliness (stressors) influence elder mistreatment. In addition, the study tested the buffer effects of social support within the stressor-mistreatment relationship.

Method: Face-to-face interviews were conducted with 897 randomly selected older adults in rural Tamil Nadu, India. Mediation and moderation models were tested using the process module.

Results: Results showed that, in addition to the direct effects, interpersonal problems also influenced mistreatment via loneliness (partially mediating model). In the moderation model, social support buffered the influence of interpersonal strain on mistreatment (unconditional direct effect) and also buffered the influence of interpersonal strain on mistreatment through loneliness (conditional indirect effects).

Discussion: Intervention on mistreatment should involve elimination of risk factors and strengthening of social resources.     

Perceived stress and resilience in Alzheimer's disease caregivers: testing moderation and mediation models of social support

Objective: The study examined whether social support functioned as a protective, resilience factor among Alzheimer's disease (AD) caregivers. Moderation and mediation models were used to test social support amid stress and resilience. Method: A cross-sectional analysis of self-reported data was conducted. Measures of demographics, perceived stress, family support, friend support, overall social support, and resilience were administered to caregiver attendees (N = 229) of two AD caregiver conferences. Hierarchical regression analysis showed the compounded impact of predictors on resilience. Odds ratios generated probability of high resilience given high stress and social supports. Social support moderation and mediation were tested via distinct series of regression equations. Path analyses illustrated effects on the models for significant moderation and/or mediation. Results: Stress negatively influenced and accounted for most variation in resilience. Social support positively influenced resilience, and caregivers with high family support had the highest probability of elevated resilience. Moderation was observed among all support factors. No social support fulfilled the complete mediation criteria. Conclusion: Evidence of social support as a protective, moderating factor yields implications for health care practitioners who deliver services to assist AD caregivers, particularly the promotion of identification and utilization of supportive familial and peer relations.     

Functional disability and depressive symptoms: longitudinal effects of activity restriction,perceived stress,and social support

Objectives: This longitudinal study investigates how activity restriction, perceived stress, and social support affect the relationship between functional disability and depressive symptoms.Method: This longitudinal study of a Taiwan population analyzed a nationally representative sample of 1268 subjects aged 60 years and over. Path analysis was used to assess interrelations among functional disability, activity restriction, perceived stress, social support, and depressive symptoms over time.Results: The analytical results supported the following relationships: (a) high functional disability were associated with high activity restriction, low social support, and high perceived stress over time, (b) high functional disability, high activity restriction, low social support, and high perceived stress were associated with high levels of depressive symptoms over time, (c) among the four factors, perceived stress exerted the strongest cross-sectional and longitudinal effect on depressive symptoms, and (d) the significant effect of prior functional disability on subsequent depressive symptoms substantially contributed to indirect changes in activity restriction, perceived stress, and social support between waves.Conclusion: The findings indicate that functional disability may contribute to subsequent depressive symptoms by reducing activities and social support. Decreased activities and social support increased perceptions of stress, which then increased depressive symptoms during the 8-year follow-up study.

原发性失眠症患者D型人格与社会支持的相关研究

目的探讨失眠症患者的D型人格特征与社会支持特点,并分析两者的关系。方法采用D型人格问卷、领悟社会支持量表,对49例有失眠症患者和82例健康人(对照组)进行评定。结果失眠症患者D型人格量表的负性情感因子评分高于正常对照组(P0.01),社交抑制评分组间无差异(P0.05);失眠症患者组社会支持总分、家庭外支持、家庭内支持三个维度的评分均明显低于对照组,其差异有统计学差异(P0.05);D型人格的负性情感(NA)及社会抑制(SI)两个维度与社会支持量表评分均呈显著负相关(相关系数-0.311～-0.469)。结论大多数失眠症患者可能属D型人格,其社会支持较差,两者存在一定的关系。     

The effect of social networks and social support on common mental disorders following specific life events

Maulik PK, Eaton WW, Bradshaw CP. The effect of social networks and social support on common mental disorders following specific life events. Objective: This study examined the association between life events and common mental disorders while accounting for social networks and social supports. Method: Participants included 1920 adults in the Baltimore Epidemiologic Catchment Area Cohort who were interviewed in 1993–1996, of whom 1071 were re‐interviewed in 2004–2005. Generalized estimating equations were used to analyze the data. Results: Social support from friends, spouse or relatives was associated with significantly reduced odds of panic disorder and psychological distress, after experiencing specific life events. Social networks or social support had no significant stress‐buffering effect. Social networks and social support had almost no direct or buffering effect on major depressive disorder, and no effect on generalized anxiety disorder and alcohol abuse or dependence disorder. Conclusion: The significant association between social support and psychological distress, rather than diagnosable mental disorders, highlights the importance of social support, especially when the severity of a mental health related problem is low.     

Culture shock and social support

Background Culture shock is a form of psychological distress associated with migration. Social support has been identified as significantly related to the onset, course and outcome of many psychological disorders. Aim The aim of this study was to examine the relationship between culture shock and social support, in terms of size, diversity of the social network and quality of support received, in Greek students, in the UK. Method A total of 133 students completed 3 self-administered questionnaires: Culture Shock Questionnaire, Social Support Questionnaire and General Health Questionnaire (GHQ-12). Results Gender and the quality of support received were found to be strongly associated with culture shock. Furthermore, culture shock was significantly positively related to the level of current dysphoria and diminished with time. Conclusion Social support is an important factor associated with the degree of culture shock and should be taken into consideration in order to protect against or help to overcome this kind of psychological distress experienced by migrants.     

Different dimensions of social support for the caregivers of patients with schizophrenia: main effect and stress-buffering models

The aims of this study were: (i) to assess the impact of caring for patients with schizophrenia on the mental health status of the caregivers; and (ii) to examine the direct and buffer effects of social support on the mental health status of these caregivers. A total of 61 key caregivers of patients with schizophrenia were administered the Chinese Health Questionnaire (CHQ) and the Measure of Support Function (MSF) self-report questionnaire to assess their mental health and social support status. The MSF questionnaire constitutes four subscales, including: (i) the perceived crisis support (PCS); (ii) the perceived routine support (PRS); (iii) the received crisis support (RCS); and (iv) the received routine support (RRS) subscale. The Positive and Negative Syndrome Scale (PANSS) was used to assess the psychopathology severity of the patients they cared for. Then the authors used the hierarchical multiple regression model to analyze the relationship between these variables. The psychopathology severity of the patients reflected by the PANSS scores correlated inversely with the caregivers' CHQ scores. Besides, the PCS subscale scores correlated positively with the caregivers' CHQ scores. Moreover, the interaction between the RCS subscale scores and the PANSS scores was significant. Significant positive correlation between the RCS and CHQ exists only in the higher PANSS subgroup, but not in the lower PANSS subgroup. The psychopathological severity of the patients has a negative impact on their caregivers' mental health. PCS has a direct effect, and RCS has a buffer effect on the mental health status of these caregivers.     

Moderators in the relationship between social contact and psychological distress among widowed adults

Objectives: This study examines: (1) the effect of widowed persons’ frequency of contact with friends and relatives on their depressive and grief symptoms six months following spousal loss and (2) the extent to which the effects of social contact are contingent upon the degree of emotional support received from these relationships and the congruence between widowed persons’ preferred and actual levels of social contact.

Method: Analyses are based on the Changing Lives of Older Couples (CLOC) study, a prospective study of a two-stage area probability sample of 1532 married men and women aged 65 or older. Depressive and grief symptoms, six months after spousal loss, were regressed on social contact, support, and congruence between preferred and actual social contact.

Results: Frequency of contact did not have a significant influence on psychological distress when contextual factors are controlled. Social support and the incongruence between preferred and actual social contact were significantly associated with decreased psychological distress for several outcomes. As for the moderating effects of social support and incongruence on the link between social contact and distress, those who had high social contact and high social support experienced less anger and fewer intrusive thoughts than their counterparts; and those who had low social contact but preferred high social contact experienced greater anger.

Conclusion: The findings highlight the importance of understanding the quality of widowed persons’ relationships as well as the congruence between their preferred and actual social contact.     

The correlation between gray matter volume and perceived social support: A voxel-based morphometry study

Social support refers to interpersonal exchanges that include the combinations of aid, affirmation and affection. Perceived social support is a kind of subjective judgment of one’s availability of social support. In spite of the importance of perceived social support to health, however, its neural substrate remains unknown. To address this question, voxel-based morphometry was employed to investigate the neural bases of individual differences in responses to the Perceived Social Support Scale (PSSS) in healthy volunteers (144 men and 203 women; mean age = 19.9; SD = 1.33, age range : 17–27). As a result, multiple regression analysis revealed that the PSSS scores were significantly and positively correlated with gray matter volume in a cluster that mainly included areas in posterior parts of posterior cingulate cortex, bilateral lingual cortex, left occipital lobe and cuneus. Highly-supported individuals had larger gray matter volume in these brain regions, implying a relatively high level of ability to engage in self-referential processes and social cognition. Our results provide a biological basis for exploring perceived social support particularly in relationship to various health parameters and outcomes.
