Items can be combined into DSM - oriented scales, of which the following four were used in this study: affective problems (13 items, e.g., «There are few things that I enjoy»), anxiety problems (6 items, e.g., «I am too scared or anxious»), and oppositional and
conduct problems (which were combined because of the
low frequency of these symptoms; 21 items, e.g., «I am disobedient
at home», «I fight a lot»).
