JTV is 4 items (‘I had a happy childhood’, ‘my parents greatly loved each other’, ‘I got the attention that I needed’, and ‘my privacy was respected’) from Dutch questionnaire on adverse childhood experiences, with higher scores reflecting higher level of happy childhood experiences (Arntz et al., 1996). SCL-90 is from Symptom Check List-90 (SCL-90) questionnaire (Derogatis, 1977), sumscore of all items.
