Performance of an abbreviated version of the Lubben Social Network Scale among three European community-dwelling older adult populations

PURPOSE: There is a need for valid and reliable short scales that can be used to assess social networks and social supports and to screen for social isolation in older persons. DESIGN AND METHODS: The present study is a cross-national and cross-cultural evaluation of the performance of an abbreviated version of the Lubben Social Network Scale (LSNS-6), which was used to screen for social isolation among community-dwelling older adult populations in three European countries. Based on the concept of lack of redundancy of social ties we defined clinical cut-points of the LSNS-6 for identifying persons deemed at risk for social isolation. RESULTS: Among all three samples, the LSNS-6 and two subscales (Family and Friends) demonstrated high levels of internal consistency, stable factor structures, and high correlations with criterion variables. The proposed clinical cut-points showed good convergent validity, and classified 20% of the respondents in Hamburg, 11% of those in Solothurn (Switzerland), and 15% of those in London as at risk for social isolation. IMPLICATIONS: We conclude that abbreviated scales such as the LSNS-6 should be considered for inclusion in practice protocols of gerontological practitioners. Screening older persons based on the LSNS-6 provides quantitative information on their family and friendship ties, and identifies persons at increased risk for social isolation who might benefit from in-depth assessment and targeted interventions.

Investigation of the Network Construction Behaviour on Social Networking Sites

By enabling connections between individuals, Social Networking Sites, such as Facebook, promise to create significant individual as well as social value. Encouraging connections between users is also crucial for service providers who increasingly rely on social advertising and viral marketing campaigns as important sources of their revenue. Consequently, understanding user’s network construction behavior becomes critical. However, previous studies offer only few scattered insights into this research question. In order to fill this gap, we employ Grounded Theory methodology to derive a comprehensive model of network construction behavior on social networking sites. In the following step we assess two Structural Equation Models to gain refined insights into the motivation to send and accept friendship requests – two network expansion strategies. Based on our findings, we offer recommendations for social network providers.

Theory after Dialogue: Christian-Muslim Engagement Today and Tomorrow

The phenomenon of Christian–Muslim dialogue has had a very chequered history. At varying times, three broad modes of engagement can be said to have operated: antipathy, affinity and inquiry, and these three modes can be found still in today's world. In some places, hostility and antipathy abound. In others, voices and actions express cordial friendship, détente and affinity. In this latter climate, the prospect of engagement in mutual inquiry and cooperative ventures is not only theoretically possible, but actively pursued, and in the first decade of the twenty-first century, a number of notable initiatives in the arena of mutual inquiry have taken place. This article addresses aspects of the context and development of Christian–Muslim dialogue as a modern phenomenon, and then turns to a review of three twenty-first century developments – the Building Bridges seminar series; the Stuttgart-based Christian–Muslim Theological Forum and the “Common Word” letter. It also reflects on the models and theology of dialogue, including not only theology for dialogue, but also theology in and – importantly – after dialogue.
