It contains 54 items organized in 13 subscales, loading five dimensions: problem-focused coping and positive cognitive restructuring, distraction coping strategies, avoidance coping strategies, and support-seeking strategies. Both problem-focused coping and positive cognitive restructuring are considered dimensions of active coping. Children request to assess how frequently they usually adopt the coping strategies described in the item on a 4-point Likert scale (1= never; 5= always).For each scale and subscale, the score is the mean of scores of the scale items.

The questionnaire includes a section devoted to demographics (i.e., gender, present age, age at the time of diagnosis, nationality, etc.) and to clinical data (eg. type of disease, treatments, other traumatic events, etc.). Only the parents' version contains the section related to personal and clinical data. An additional section aims to explore the thoughts, feelings and behaviour of child, adolescents and parents in the main moments of the patient's disease (communication of diagnosis, treatment, follow-up) through open and closed questions.

Data are qualitative, no scoring, and will be helpful for cathegorization during statistical analyses.
