Social support is broad term encompassing a variety of constructs, including support perceptions (perceived support) and receipt of supportive behaviors (received support). Of these constructs, only perceived support has been regarded as consistently linked to health, and researchers have offered differing assessments of the strength of the received-perceived support relationship. An overall estimate of the received-perceived support relationship would clearly further the dialogue on the relationship between received and perceived support and thus assist in the theoretical development of the field. This study evaluated all available studies using the Inventory of Socially Supportive Behaviors (ISSB; Barrera, Sandler, & Ramsey, 1981, American Journal of Community Psychology, 9, 435-447) and any measure of perceived social support. Using effect sizes from 23 studies, we found an average correlation of r = .35, p < .001. Implications of this estimate for further development of models of social support as well as interventions to enhance social support are discussed.

Objective Understanding individual differences in the psychobiology of the stress response is critical to grasping how psychosocial factors contribute to racial and ethnic health disparities. However, the ways in which environmentally sensitive biological systems coordinate in response to acute stress is not well understood. We employed a social-evaluative stressor task to investigate coordination among the autonomic nervous system (ANS), hypothalamic-pituitary-adrenal (HPA) axis, immune/inflammatory system, and neurotrophic response system in a community sample of 85 healthy African American men and women. Methods Six saliva samples – two collected before and four collected during and after the stressor – were assayed for cortisol and dehydroepiandrosterone-sulfate (DHEAs; HPA-axis markers), salivary α amylase (sAA; ANS marker), salivary c-reactive protein (sCRP; inflammatory/immune marker), and salivary nerve growth factor (sNGF; neurotrophic marker). Individual differences in perceived discrimination and racial identity were also measured. Results Factor analysis demonstrated that stress systems were largely dissociated before stressor exposure, but became aligned during event and recovery phases into functional biological stress responses (factor loadings .71to.96). Coordinated responses were related to interactions of perceived discrimination and racial identity: when racial identity was strong, high perceived discrimination was associated with low hypothalamic-pituitary-adrenal (HPA) axis arousal at baseline (B’s = .68 to.72, p < .001) and during the task (B’s =.46 to .62, p ≤ .049), and a robust inflammatory response (sCRP) during recovery (B’s =.72 to.94, p ≤ .002). Conclusion Culturally-relevant social perceptions are linked to a specific pattern of changing alignment in biological stress responses. Better understanding these links may significantly advance understanding of stress-related illnesses and health disparities.

Both theory and research suggest that beliefs about justice for the self are distinct from beliefs about justice for others. Self-other differences, however, have not yet intersected with research on procedural and distributive justice. We examined the psychometrics and validity of a proposed four-dimensional measure of procedural and distributive justice beliefs for self and others. Participants from three samples (total N = 1463) completed dispositional measures of beliefs about fair outcomes (distributive justice beliefs) and processes (procedural justice beliefs). These measures were modified and expanded to record beliefs about justice for the self and justice for others. We also administered measures of well-being and harsh social attitudes. Factor analyses strongly supported the proposed four-factor model. In addition, higher-order self-others and procedural-distributive factors were indicated by theoretically appropriate lower-level factors. Finally, multiple regression analyses provided evidence for idiosyncratic links between four-factor individual differences and measures of well-being and harsh social attitudes. The proposed four-factor operationalization can provide individual differences researchers with a useful tool for bridging two important areas of justice theory and research that previously have been linked to health behavior, well-being, and harsh social attitudes.

Focusing on improving both the psychosocial work environment and organizational efficiency might contribute to decreased employee stress, improved mental well-being, and organizational performance.

Recent approaches to stress regulation have emphasized coordination among multiple biological systems. This study builds on evidence that hypothalamic-pituitary-adrenal (HPA) axis activity should be considered in coordination with other stress-sensitive biological systems to characterize healthy responses. Healthy African-Americans (n=115) completed the Trier Social Stress Test, and biological responses were assessed through salivary cortisol, dehydroepiandrosterone-sulfate (DHEA-S), alpha amylase (sAA), and C-reactive protein (sCRP). Multilevel modeling demonstrated that cortisol responses typically aligned with changes in DHEA-S, sAA, and sCRP across the session. At the same time, the degree of cortisol coordination with sAA and sCRP varied by participants’ subjective stress following the task; participants with higher secondary stress appraisals showed greater cortisol-sAA alignment, whereas those experiencing more negative affect showed greater cortisol-sCRP alignment. Results highlight the importance of a multisystem approach to stress and suggest that positive HPA axis coordination with the autonomic response, but not with the immune/inflammatory response, may be adaptive.

What is already known on this subject? African Americans are at an increased risk of both developing and dying from colorectal cancer (CRC). These disparities can be attributed in large part to deficits in the use of CRC screening among African Americans. Guided by prospect theory, available literature suggests that selectively pairing gain and loss-framed messaging with illness prevention and detection can better promote adaptive health behaviour. Specifically, loss-framed messages that emphasize the potential costs of failing to act may promote better use of illness detection behaviours, such as CRC screening. Emerging literature highlights the potential for cultural differences in the effects of gain and loss messaging on health behaviour, especially among collectivist or interdependent cultures. What does this study add? This study is the first to identify a potential and important cultural difference in the effect of message framing on cancer screening among African Americans, whereby gain-framed messaging better compelled receptivity to CRC screening. This study is also the first to show that the use of loss-framed messaging may reduce receptivity to CRC screening among African Americans by increasing perceived racism. This study demonstrates that simultaneously including a culturally targeted personal prevention message may attenuate the negative effects of loss-framed messaging on CRC screening among African Americans.
