Because individuals' fundamental right to water is often taken for granted, little is known about why individuals participate in water activism. We examine how individuals identify with and intend to participate in the Italian Water Movement to defend the "public management" of water supply. Building on the collective-action literature, we test an explanatory model in which the perceived violation of the right to water and group and participative-efficacy beliefs increase movement identification, which predicts subsequent activism. Study 1 (N = 153 activists) largely confirmed our hypotheses: right violation and participative efficacy uniquely influenced movement identification, which in turn predicted activism. Study 2 corroborated these findings by employing a broader sample of 132 Italian citizens, with right violation, participative and group-efficacy beliefs predicting movement identification, which in turn predicted activism. We discuss the theoretical and practical implications of these findings.

Civic participation in community life and within community organiza-tions is generally considered as associated with positive outcomes for youth development and well-being. However, supportive empirical evidence on such benefits is still limited, as well as on the processes that may explain such positive outcomes. In this paper, we examined the impact of young people's participation different community and youth organizations on Social well-being, and the medi-ating role of Sense of community (SoC) and Empowerment. The sample comprised 835 adolescents and young adults, aged 16-26 years old (M = 20.8). 414 partici-pants were males (49.6 %) and 421 participants were females (50.4 %). Results confirm that organizational membership of volunteer, youth, and religious associations significantly enhances Social well-being, both directly and through the mediation of SoC and Empowerment. Membership of leisure and recreational associations only marginally and indirectly affects Social well-being through the mediation of Empowerment.

Internet forums represent a useful but understudied resource to understand psychosocial aspects of living with systemic lupus erythematosus. This study was aimed to describe the demand/supply of social support through the Internet in relation with the description of personal illness experiences. All the posts (118) from an Italian forum for systemic lupus erythematosus patients were collected and analyzed combining qualitative content analysis with statistical textual analysis. The results showed different purposes for posts: starting new relationships, seeking information, receiving emotional support, and giving a contribution. Lexical analysis identified three ways of describing patients' experiences. Discussion focuses on the relationship between the requested/offered support and systemic lupus erythematosus experiences.

In the last decades, with the improvement of life expectancies for systemic lupus erythematosus (SLE) patients, the relationship between social support and health in this population has received a considerable amount of attention in behavioural medicine and health psychology. This paper is the first to review research studies which specifically investigated perceived social support in relation to SLE patients' health outcomes (quality of life, disease activity and damage). Starting with a descriptive approach to social support perceived by patients with SLE, the research evidence on the impact of social support on health is presented. These studies demonstrate that the consideration of social support is critical in predicting disease activity, damage and quality of life (both physical and psychological components) although the precise ways in which social support contributes to health are not yet completely understood. Discussing the results, the authors offer some suggestions which could guide further research in this field. Finally, clinical and non-clinical implications of the findings are discussed.
