<p>Trauma can lead to mental illness, but it can also result in positive outcomes known as post-traumatic growth (PTG). Many cancer survivors who experience trauma report experiencing PTG, which is connected to psychological resilience—the ability to adapt and cope with stress. Metacognitive skills, cognitions about cognitions, are critical for managing life challenges. Previous studies assessing metacognition in cancer patients have primarily utilized self-report scales to evaluate metacognitive cognitions. In contrast, the present study is the first to assess metacognitive skills in cancer patients using a semi-structured, interview-based approach with interviewer-administered scoring Metacognition Assessment Scale-Abbreviated (MAS-A). This study investigated the relationship between metacognitive skills with psychological resilience and PTG in cancer survivors. The study included 45 cancer patients in remission. Participants completed assessments: the MAS-A for metacognitive skills, the Post-traumatic Growth Inventory (PTGI) for PTG, the Resilience Scale for Adults (RSA) for resilience, World Health Organization Quality of Life Scale-Brief for life quality. MAS-A is interviewer-rated, while the remaining scales are self-reports. There was no significant relationship between the MAS-A and PTGI scores (<i>p</i> &gt; .05). However, positive correlations were found between the MAS-A and RSA scores (<i>r</i>_<i>s</i> = .297 to .454; <i>p</i> = .048–.002). Additionally, higher PTGI- Changes in Philosophy of Life scores were found in those receiving chemotherapy and radiotherapy (<i>p</i> = .008 and .001, respectively). While metacognitive skills do not directly impact PTG, they are related to psychological resilience, a key predictor of PTG. This highlights the importance of further research on metacognitive interventions and their effectiveness in cancer patients.</p>
