As a particularly vulnerable group, children from rural areas in China whose families migrate to urban areas often encounter social exclusion, prejudice, and discrimination as they adjust to city life. Hence, migrant children may experience a sense of relative deprivation when they feel they are treated unjustly when compared to their urban counterparts. Although previous research has demonstrated that relative deprivation is a risk factor for prosocial tendencies, this association has not yet been examined in the population of migrant children in China. Further, few studies have revealed the mediating and moderating mechanisms between relative deprivation and prosocial tendencies. Therefore, this study constructed an integrated model examining the possible mediating role of perceived social support and moderating role of in-group identity on the association between relative deprivation and prosocial tendencies. A large sample of 1,630 Chinese rural-to-urban migrant children (845 girls; Mage = 12.30, SD = 1.74) completed a battery of self-report questionnaires regarding relative deprivation, prosocial tendencies, perceived social support, in-group identity, and demographic variables. The results indicated that relative deprivation was negatively correlated with migrant children's prosocial tendencies and this connection was partially mediated by perceived social support. Moderated mediation analysis further indicated that in-group identity moderated the effect of perceived social support on prosocial tendencies, with a high level of in-group identity strengthening the positive association between perceived social support and prosocial tendencies. Parents, educators, and other members of society concerned about migrant children's psychosocial adaptation should provide adequate social support resources and help them foster positive in-group identity to migrant populations to mitigate the adverse effects of relative deprivation and promote their prosocial tendencies.

To examine the relationship between relative deprivation and social anxiety, which affects mental health, and investigate the mediating role of perceived control and the moderating role of belief in a just world (BJW) in an understudied population in Asia, we surveyed 1573 rural-to-urban migrant children (48% female; Mage = 12.3, SD = 1.7) in southeast China. Relative deprivation was positively correlated with social anxiety; perceived control partially mediated this connection. Moreover, BJW moderated the indirect effect, which was stronger for male migrant children with lower levels of BJW. The limitations and practical implications of this study are discussed.

Objective: Our goal was to compare the perceptions of overseas orthopaedic volunteers and their hosts in low-and middle-income countries (LMICs) regarding the role of international volunteerism. We also sought to determine if differences in perception exist between trainee and fully trained orthoapedic surgeon volunteers. Methods: Surveys with similar multiple-choice and open-ended questions were administered to 163 Health Volunteers Overseas orthopaedic volunteers (response rate 45%) and 53 members of the host orthopaedic staff (response rate 40%). Fifty-four volunteers and 20 hosts also contributed open-ended responses. Quantitative responses were analyzed for significance using Mantel-Haenzel x 2 tests. Open-ended responses were coded using thematic analysis.Results: Both the international volunteers and their LMIC hosts agreed that volunteers learned new skills while volunteering. Both groups believed that international volunteerism had a positive overall impact on the local practice, but hosts viewed these benefits more favorably than volunteers did. LMIC staff believed that, besides altruistic reasons, volunteers were also motivated by professional gains, diverging from volunteer responses. In open-ended responses, hosts desired longer term commitments from volunteers and had some concerns regarding volunteers' qualifications. Between volunteer trainees and fully trained surgeons, trainees were more likely to be motivated by personal benefits. Conclusion:Efforts must be made to further align the expectations and goals of volunteers and their hosts in LMICs. Certain measures such as predeparture orientations for volunteers and developing a more longitudinal and bidirectional experience may enhance the impact of orthopaedic volunteerism in LMICs. Further studies are needed to explore the impact of international orthopaedic volunteerism on the host population.
