Methods Of the 319 in- and outpatients referred to the CPT at University Children s Hospital Zurich from 20052006 a sample of 180 children was drawn to contact for a follow-up. The children and their parents were asked to participate in a face-to-face interview at the hospital in 42 cases the children and parents consented to do so. Alternatively the parents could take part in a telephone interview n 39 . Non-participation resulted because no contact or adequate communication in German French or English could be established n 49 or because the parents or children refused to participate n 50 . Results Participants and non-participants did not differ significantly in mean child age at follow-up gender family status place of residence certainty and type of maltreatment and type of perpetrator. However the child s nationality had a significant impact Percentages of foreign nationals were higher in the fully participating group 45 n 19 and the non-contactable group 53 n 26 and significantly lower in the refusal 26 n 10 and the telephone interview group 18 n 9 . Although a high percentage of families had moved in the few years since the CPT intervention 32 n 57 the percentage of moves was not significantly higher in non-participants compared to participants. Conclusions Further research is needed to support these results in .
