Diversity and Community Cohesion

==Diversity and Community Cohesion==
where individuals exhibit at least some tendency to form relationships with similar others (i.e. bH[0) and at least some tendency to form relationships with nearby others (i.e. bP[0), diversity and sense of community are nega- tively related. It is important to note that all studies of human social networks have observed behavioral tenden- cies toward both homophily and proximity, while none have found worlds where one or both of these behavioral tendencies was missing. Thus, while the findings illustrated in Fig. 4 suggest that diversity and sense of community are negatively related in a typical world, those illustrated in Fig. 5 suggest this negative relationship would persist in all reasonably likely worlds.

> Putnam's study reveals that immigration and diversity not only reduce social capital between ethnic groups, but also within the groups themselves. Trust, even for members of one's own race, is lower, altruism and community cooperation rarer, friendships fewer.

Abstract

Background
Aetiological mechanisms underlying ethnic density associations with psychosis remain unclear.
Aims
To assess potential mechanisms underlying the observation that minority ethnic groups experience an increased risk of psychosis when living in neighbourhoods of lower own-group density.
Method
Multilevel analysis of nationally representative community-level data (from the Ethnic Minorities Psychiatric Illness Rates in the Community survey), which included the main minority ethnic groups living in England, and a White British group. Structured instruments assessed discrimination, chronic strains and social support. The Psychosis Screening Questionnaire ascertained psychotic experiences.
Results
For every ten percentage point reduction in own-group density, the relative odds of reporting psychotic experiences increased 1.07 times (95% CI 1.01-1.14, P = 0.03 (trend)) for the total minority ethnic sample. In general, people living in areas of lower own-group density experienced greater social adversity that was in turn associated with reporting psychotic experiences.
Conclusions
People resident in neighbourhoods of higher own-group density experience 'buffering' effects from the social risk factors for psychosis.
