“…The SOC seems to be relatively stable over time, but not as stable as initially assumed (Eriksson & Lindström, 2011). Research findings show that the SOC develops over the entire lifespan, in other words it increases with age (Feldt et al, 2007(Feldt et al, , 2011Nilsson, Leppert, Simonsson, & Starrin, 2010). In the HeSSup study among 18.525 Finns, the SOC seemed to increase with age in terms of being more stable among subjects aged 30 and over (stability coefficient 0.81) than among younger adults (0.70) (Feldt et al, 2007).…”
