  1. *Model developed from backward stepwise selection of all socio-demographic and clinical predictors from the fully adjusted model fulfilling the inclusion criteria with p = 0.05 and exclusion criteria with p > 0.1 reported with unstandardised coefficients (β), standard error, p-values (p) and Adjusted R Square (R 2). Coding of the independent variables: sex; female = 0, male = 1, children; no = 0, yes = 1, employment; no = 0, yes = 1, education status; primary school = 1, high school = 2, college/university = 3, heart disease in family; LQTS = 1, HCM = 2, sudden death in family; no = 0, yes = 1, genetic testing in family; no = 0, yes = 1, referral; by family member = 0, by physician = 1, clinical status; family risk = 0, LQTS = 1, HCM = 2. Age was treated as continuous. The dependent variables: The SF-36 health status domains were treated as continuous (0-100).
