There is not much evidence on the effects of south–south migration and its consequences on physical and mental health. Our objective was to examine the mediating role of Acculturative Stress in the association between ethnic discrimination and racial discrimination with physical and mental health. This research is a non-experimental, analytical, cross-sectional study. A total of 976 adult Colombian migrants living in Chile were interviewed. We used the Everyday Discrimination Scale, the acculturative stress scale, and the Medical Outcomes Study Short Form (SF-12) for health status; we found that racial and ethnic discrimination had a negative effect on physical and mental health. In the simultaneous presence of both types of discrimination, racial discrimination was completely absorbed by ethnic discrimination, the latter becoming a total mediator of the effect of racial discrimination on mental and physical health. Our findings are consistent with the literature, which suggests that there are various types of discrimination which, individually or in their intersectionality, can have negative effects on health.

There is abundant evidence about the negative impact of discrimination on well-being, but less research on factors that can reduce this negative effect, mainly focused on North American samples and with incipient development on South–South migration. The objective of this research was to analyze the effect of ethnic identity on the relationship between the experience of racial and ethnic discrimination and psychological well-being in Colombian immigrants living in Chile. A total of 962 immigrants over the age of 18 from three cities in Chile participated. Of these, 50.7% were women. The average age was 35 years (SD = 10.23). Participants were evaluated using Ryff’s Psychological Well-Being Scales, Phinney’s adapted version of the Multigroup Ethnic Identity Scale, and Krieger’s Discrimination Experience Scale. After the analysis of the measurement models, a mediation model was analyzed using structural equations. The results provide evidence that ethnic and racial discrimination have negative effects on psychological well-being, with the effect of racial discrimination being greater. Likewise, ethnic identity has positive effects on psychological well-being and partially and completely mediates the effects of ethnic and racial discrimination on psychological well-being. The full effect of discrimination on psychological well-being, mediated by ethnic identity, is exercised only by racial discrimination and not by ethnic discrimination.

This study examined the prevalence of victimization and polyvictimization and gender differences in young adults from Arica in northern Chile. In all, 718 college students participated (46.9% men, 53.1% women), aged between 17 and 28 years old (M = 21.6; SD = 4.11). The Spanish version of Juvenile Victimization Questionnaire ( JVQ) was used to access five categories of child victimization (conventional crime, child maltreatment, peer and siblings victimization, sexual victimization, and indirect victimization). In total, 98.7% of young adults reported at least one type of victimization throughout their life. In general, males are more exposed to victimization for conventional crimes and indirect victimization and women to sexual victimization and bullying. A total of 89.1% of the sample was considered polyvictims (i.e., experienced five or more forms of victimization). This research provides information about the epidemiology of victimization and polyvictimization in young adults in the international context, and is the first study from this point of view in a South American country. The results show that young adults in northern Chile experience a high level of victimization, even mostly higher than others studies realized in the international context. Gender is a variable that has a significant influence and must be taken into account in the analyses of this complex subject of study.

(1) Background: Migration causes effects on the people who migrate and on the societies that receive them, which can be positive or negative, depending on the characteristics of the interaction. One negative effect is the emergence of mental health disorders associated with the presence of discrimination, a relationship for which there is abundant evidence, although there is less research on factors that may alter this effect. (2) Objective: To evaluate the possible mediating role of optimism and intolerance to uncertainty in the relationship between discrimination and mental health. (3) Method: Nine hundred and nineteen adult Colombian migrants residing in Chile, 49.5% were men and 50.5% women, ages from 18 to 65 years, were evaluated. The Discrimination Experience Scale, BDI-IA Inventory, BAI, LOT-R and the Intolerance to Uncertainty Scale were applied. The effects were estimated using structural equation modeling. (4) Results: A mediating effect of both dispositional optimism and intolerance to uncertainty on the relationship between discrimination and mental symptomatology was observed. (5) Conclusions: The impact on individual suffering and the social cost of mental health problems require investigating variables on the relationship between discrimination and mental health, including mediators of this relationship, which turn out to be central elements in the development of future strategies for the reduction of anxiety and depression symptoms.

Migration processes can often trigger negative interactions with the context, generating problems in both the physical and mental health of migrants, which have an impact on both their well-being and their quality of life. In this framework, the research aimed to assess the mediating effect of ethnic identity and collective self-esteem on the inverse relationship between mental health problems and quality of life. Data were collected from 908 first-generation Colombian migrants living in Chile, of whom 50.2% were women and with an average age of 35 years. They were assessed with The World Health Organization Quality of Life (WHOQoL)-Bref, Smith’s ethnic identity questionnaire, Basabe’s collective self-esteem, and Beck’s Anxiety and Depression questionnaires. The results provide evidence that both collective self-esteem and ethnic identity exert a partial mediation effect on the relationship between anxiety and depression on quality of life. The study provides evidence of the protective role that the maintenance and reinforcement of ethnic identity and collective self-esteem can have, with a view to strengthening the planning of interventions both in the field of prevention of mental health problems and in the improvement of quality of life based on evidence.
