Emotional Regulation

Emotional regulation will be assessed using the Emotion Regulation Questionnaire for Children and Adolescents. This self-report scale evaluates the use of emotional regulation strategies across two subscales: cognitive reappraisal and expressive suppression. The scale consists of 10 items rated on a 5-point Likert scale. Higher subscale scores indicate more frequent use of the corresponding emotional regulation strategy.

Symptom Burden

Symptom burden will be assessed using the Symptom Screening in Pediatrics Tool (SSPedi), a validated self-report instrument for children aged 8-18 years undergoing cancer treatment. The scale includes 15 common physical and psychological symptoms experienced during chemotherapy. Each item is rated on a 5-point Likert scale, with total scores ranging from 0 to 60. Higher scores indicate greater symptom burden and distress.

State Anxiety

State anxiety will be measured using the State Anxiety Inventory for Children, a 20-item self-report scale designed to assess situational anxiety levels in children and adolescents aged 8-18 years. Items are rated on a 4-point Likert scale, with total scores ranging from 20 to 80. Higher scores reflect higher levels of state anxiety.

Intervention Acceptability

Intervention acceptability and participant satisfaction will be assessed using a researcher-developed process evaluation form. Children will rate their perceived comfort, enjoyment, and satisfaction with the intervention on a numeric scale ranging from 0 to 5, with higher scores indicating greater acceptability.
