With a little help from my friends: A computational model for the role of social support in mood regulation

The growing interest in the role of social support in mental and physical health has led to the development of several intelligent systems that aim to use social mechanisms to simulate healthy behaviour. In this paper a computational model of a human agent is presented which describes the effect of social support on mood. According to the literature, social support can either refer to the social resources that individuals perceive to be available or to the support that is actually provided in problematic situations. The proposed model distinguishes between both roles of social support. The role of social network characteristics has been taken into account, as an individual can perceive or receive social support through his/her social network. In addition, the number of connections (friends), strength of ties (relationships), social isolation and social integration have been studied. Simulation experiments have been done to analyze the effect of the different types of support in different scenarios and also to analyze the role of various social network characteristics on the mood level. It is shown that support can help to reduce the induced stress and thus can contribute to healthy mood regulation and prevention of depression. The presented model provides a basis for an intelligent support system for people with mood regulation problems that take the social network of people into account.     

Effets du soutien organisationnel perçu et des caractéristiques de l’emploi sur l’anxiété au travail et l’épuisement professionnel : le rôle médiateur de la satisfaction des besoins psychologiques

Based on organizational support theory, job characteristics model, and self-determination theory, we examined the mechanisms that underlie the relations between organizational factors and ill-being. Specifically, the main purpose of the present study was to demonstrate the mediating role of the psychological needs for autonomy (i.e., the need for individuals to feel volitional and responsible for their own behavior), competence (i.e., the need for individuals to interact effectively with their environment), and relatedness (i.e., the need for individuals to feel connected and accepted by others), in the relationships of perceived organizational support (i.e., the degree to which employees believe that their organization values their contributions and cares about their well-being) and three motivational job characteristics (i.e., task identity, task significance, and work scheduling autonomy) to job anxiety and burnout. This is the first research, to the best of our knowledge, to test for the joint effects of perceived organizational support and motivational job characteristics on job anxiety and burnout through psychological need satisfaction. Four hundred and fifty-seven employees (216 men and 241 women) from different sectors (i.e., industry, trade, crafts) took part in the study. Fifty-seven participants worked in companies with less than 10 employees, 105 in companies with 11–49 employees, 138 in companies with 50–249 employees, 33 in companies with 250–499 employees, and 124 in companies with more than 500 employees. The hypothesized model was tested with structural equation modeling analyses. Results provided support for our hypotheses and revealed that all hypothesized paths were significant. Specifically, our results showed that perceived organizational support and job characteristics were positively related to psychological need satisfaction. In addition, satisfaction of these psychological needs was negatively associated with job anxiety and burnout. Therefore, feelings of autonomy, competence, and relatedness play a central role in the development or reduction of well- and ill-being at work. These results are consistent with previous research in the work context, which has shown that social factors (e.g., autonomy-supportive behaviors) have significant effects on workplace mental health through their influence on psychological need satisfaction. Practical and research implications as well as suggestions for future research are discussed.     

Attitudes toward health-messages: The link between perceived attention and subjective strength

IntroductionMany efforts are invested in promoting healthy attitudes and behaviors; nonetheless there is no clear, definitive evidence of sustained effectiveness of those efforts in all cases.ObjectiveThe present study examined the role of perceived attention in changing attitudes toward vegetable consumption as well as the perceived stability and resistance of those changes (attitude strength).MethodParticipants were randomly assigned to read a strong or weak health communication arguing in favor of vegetable consumption. After reading the message, participants reported attitudes toward this health issue, the perceived attention, and the perceived strength associated with their evaluations.ResultsParticipants who reported high (vs. low) perceived attention showed a greater effect of argument quality on persuasion. Furthermore, such participants also reported stronger attitudes compared to those who reported low perceived attention.ConclusionThis study showed that attitudes toward vegetable consumption can be changed after reading a persuasive message, and that the extent of perceived attention moderated the extent to which those changes were perceived as stable and resistant (stronger attitudes).     

The Influence of Neighborhood Aesthetics,Safety, and Social Cohesion on Perceived Stress in Disadvantaged Communities

Limited research has explored how specific elements of physical and social environments influence mental health indicators such as perceived stress, or whether such associations are moderated by gender. This study examined the relationship between selected neighborhood characteristics and perceived stress levels within a primarily low‐income, older, African‐American population in a mid‐sized city in the Southeastern U.S. Residents (n = 394; mean age=55.3 years, 70.9% female, 89.3% African American) from eight historically disadvantaged neighborhoods completed surveys measuring perceptions of neighborhood safety, social cohesion, aesthetics, and stress. Multivariate linear regression models examined the association between each of the three neighborhood characteristics and perceived stress. Greater perceived safety, improved neighborhood aesthetics, and social cohesion were significantly associated with lower perceived stress. These associations were not moderated by gender. These findings suggest that improving social attributes of neighborhoods may have positive impacts on stress and related benefits for population health. Future research should examine how neighborhood characteristics influence stress over time.     

Not all cultural values are created equal: Cultural change in China reexamined through Google books

Given its major transformations in recent decades, China has figured prominently in research on cultural change. Previous research converges in showing a general trend towards individualism in contemporary China while noting that rising individualism tends to coexist with enduring collectivism. To further understand this, we tested whether perceived traditional importance of cultural values would modulate the trajectory of cultural change reflected in word usage frequencies in published books. We re‐analysed Google's Chinese corpus since 1980 based on a broad sample of words associated with individualism–collectivism. We replicated the pattern of rising individualism and declining collectivism among words of modest and low perceived traditional importance. Most important, however, collectivistic words of high perceived traditional importance increased in usage frequencies with time, thus departing from the general trend towards individualism. Overall, our research underscores the role of core culture in cultural maintenance during times of rapid cultural change.     

留守儿童生活压力与孤独感、幸福感的关系:心理资本的中介与调节作用

Perceived stress,recurrent pain,and aggregate salivary cortisol measures in mid‐adolescent girls and boys

Measures of perceived stress have been criticized for theoretical inconsistency. However, the validated pressure activation stress scale has been suggested as a theoretically sound alternative. But it is unclear how pressure and activation stress relate to objective and subjective measures including commonly used aggregate cortisol measures and health complaints respectively. Specifically, this study aimed at investigating how pressure and activation stress were related to aggregate salivary cortisol measures and recurrent pain in mid‐adolescent girls and boys. Mid‐adolescents (119 girls and 56 boys) provided self‐reports in questionnaires on activation and pressure stress and recurrent pain (headache, stomach ache, neck/shoulder and back pain). Additionally, adolescents sampled saliva during an ordinary school day: (1) immediately at awakening; (2) 30 minutes after waking up; (3) 60 minutes after waking up, and (4) at 8 p.m. These samples were analyzed for cortisol. Hierarchical regressions showed no statistically significant associations between activation and pressure stress and cortisol, neither for girls nor for boys. However, activation and pressure stress were significantly associated with recurrent pain but only for girls. The findings may relate to subjective and objective measures reflecting distinct aspects of stress‐related functioning. However, the study participants included mid‐adolescents whose bodily systems are flexible and still relatively unaffected by the strain of their daily stress perceptions. To conclude, the non‐significant relationships between activation and pressure stress and commonly used aggregate measures of cortisol adds to the understanding of how perceived stress may relate to physiological functioning in the daily life of adolescents when using such aggregate measures.     

The vocational well-being of workers with childhood onset of disability: Life satisfaction and perceived workplace discrimination

Workers with disabilities are understudied, and workers with childhood onset of disability have been excluded from many of the studies on disability and work that do exist. This research compares the effects of childhood and adult onset of disability in a nationally representative sample of workers with disabilities. Educational disruptions due to disability status in childhood are negatively associated with life satisfaction and positively associated with perceived discrimination. Although age is associated with increased life satisfaction and decreased perceptions of discrimination for workers with adult disability onset, age is unrelated to these outcomes for workers with childhood disability onset. Receiving workplace accommodations is positively associated with satisfaction and negatively associated with discrimination for both groups, however, these relationships are stronger in magnitude for the childhood disability onset group. Organizational environments, both in education and in the workplace, play a critical role in the vocational well-being of workers with childhood disability onset.
