Evaluation of a child's perceived self-competence during treatment for cancer

The purpose of this study was to evaluate the effect of self-hypnosis on the perceived self-competence of children undergoing treatment for cancer and to determine longitudinal differences in perception of self-competence over time. Twenty-two children were randomized into an experimental group (taught self-hypnosis) and a control group (given standard care). Data were collected using the Harter Perceived Self-Competence Profile (HPSCP) during four courses of chemotherapy. A decrease in mean scores for the control group was found compared with the hypnosis group, which showed an increase in mean scores in five of six domains. Both groups showed a statistically significant increase in the scholastic cognitive domain and social acceptance domain from the time of diagnosis compared with the second test period. Ten children had a visible physical disability. These children were found to have significant decreases in the domains of athletic competence, social acceptance, and global self-worth. Decreases remained significant throughout all test periods in the athletic competence domain for the children with a visible physical disability. This study is unique in that the researchers evaluated children's perception of self-competence over time. These findings support previous studies and identify the need for nurses to become actively involved in helping children develop effective coping skills during chemotherapy for cancer.
