The Lexical Association Technique: A randomized controlled trial with breast cancer patients.

Low self-esteem is a vulnerability factor for depressive disorders, and the prevention of psychological disorders is essential in cancer patients. The enhancement of self-esteem in breast cancer patients may therefore be an appropriate clinical target. Previous studies have shown the efficacy of the Lexical Association Technique to enhance self-esteem in healthy subjects. This study aims to test the clinical efficacy and acceptability of the Lexical Association Technique on the self-esteem of cancer patients. A double-blind randomized controlled trial was conducted on 63 breast cancer patients during their radiotherapy treatment. Global self-esteem measures were taken using the Rosenberg Self-Esteem Scale before and after the Lexical Association Technique and 1 month after its end. The results showed a significant improvement in global self-esteem in patients immediately after performing the Lexical Association Technique compared to an active control group. However, the positive effects did not last 1 month. These results confirm the efficacy and suitability of the Lexical Association Technique for cancer patients. Avenues of research are proposed to extend the effects of the technique and increase its transdiagnostic applicability.
