“…Various secondary and process measures (Subjective Units of Disturbance; Wolpe, 1982; and Validity of Cognition scales; Shapiro, 1989) were taken to corroborate any improvements in trauma-specific symptoms and to determine whether such improvements generalised to non-trauma symptoms such as anxiety (State Trait Anxiety Inventory for Children; Spielberger, 1973;Hedl & Papay, 1982;Papay & Speilberger, 1986), depression (Children's Depression Scale; Lang & Tisher, 1983;Tisher, Lang-Takac & Lang 1992;Tisher, 1995) and behavioural problems (Child Behaviour Checklist; Achenbach, 1991;Saxe et al, 2003;Vila et al, 2001). Parent measures included known correlates of childhood PTSD that were likely to impact upon recovery (Langeland & Olff, 2008) (the Child Post-Traumatic Stress -Reaction Index: Parent Questionnaire (henceforth referred to as the Parent PTS-RI), Nader, 1994;General Health Questionnaire -12, Goldberg, 1978; the Impact of Events Scale, Horowitz, Wilner, & Alvarez, 1979; the General Functioning Scale derived from the Family Assessment Device; Epstein, Baldwin & Bishop, 1983; and a checklist of social stressors).…”
