Which of the following is likely to improve a child's adherence to medication?

Parental support and involvement can significantly enhance a child's adherence to medication for several reasons. When parents engage in the medication process, it fosters a sense of security for the child and helps them establish a routine around taking their medication. Additionally, parents can provide encouragement, explain the importance of the medication, and help the child manage any side effects or concerns they may have. This support can include reminders, tracking dosages, or even taking the medication together, which makes the process feel less isolating for the child.

In contrast, while coloring pills might make them more visually appealing, it does not address the psychological or emotional aspects of medication adherence. Increasing the dosage can lead to potential non-adherence or negative feelings about medication if the child feels overwhelmed. Limiting availability might inadvertently create a sense of scarcity or necessity that could negatively affect adherence. Thus, parental support is recognized as a key factor in helping children understand and commit to their medication regimens.
