“…Using the SOC-13 questionnaire, they assessed the sense of coherence in 429 young people with CHD (14-18 years), and found that higher sense of coherence scores and better physical health explained better quality of life in patients, compared to healthy controls ; and that sense of coherence at time 1, in a longitudinal study over a 9-month period predicted several domains of general and disease-specific perceived health at time 2 . Positive associations between the sense of coherence scores and quality of life measures were evidenced also in other samples of adolescents with CHD, for instance in Japan, in a sample of 172 adolescents aged 12-18 (Nio, 2010); in Australia, in a sample of 114 patients aged 12-20 (Wang, Hay, Clarke, & Menahem, 2014); or in Germany, in a sample of 770 adolescents aged 14-17 (Neuner et al, 2011). The SOC-13 questionnaire was used in all of these studies, except for Neuner et al's study, where the sense of coherence was measured with a shortened version, the SOC-L9 questionnaire (Schumacher, Wilz, Gunzelmann, & Brahler, 2000).…”
