Cognitive-behavioural Intervention for Anxiety, Depression and Quality of Life Among Children Receiving Chemotherapy.

Participants in the experimental group will receive five sessions of cognitive-behavioural intervention. Each session will be conducted face-to-face for 30-35 minutes a week and supplemented by home-based practices. The first session is an introductory to cognitive-behavioural intervention, the second session includes identifying, evaluating and challenging maladaptive thoughts, beliefs and behaviour, the third session includes behavioural activation, the fourth session is deep breathing, and the last session includes treatment evaluation and relapse prevention. The interventions will be delivered before chemotherapy sessions to avoid fatigue and to increase the patient's engagement with the interventions. To establish a strong therapeutic alliance and enhance intervention delivery and family support, parents will be invited to attend the introduction of the first session and the summary of each session (the last five minutes).
