[Assessing Social Resources in the Chronically Ill: Development and Initial Psychometric Testing of an Ego-centered Network Generator].

Background: The social network is one of the most significant resources during the course of the rehabilitation. However, there is a lack of short instruments in questionnaire format for the assessment of social relations in the chronically ill. We therefore developed a network generator (NWG), and tested its performance in patients with different diseases during medical rehabilitation. Methods: We tested its reliability, validity and acceptance in 882 inpatients participating in medical rehabilitation programs (cancer N=290, musculoskeletal diseases N=292, and psychosomatic diseases N=300). Findings: The NWG provides clear information about different aspects of the social network of these subgroups with satisfying psychometric characteristics. Conclusions: The NWG can be applied as short assessment of positive social relationships that, in practice, are important resources during the whole rehabilitation process of the chronically ill.
