The intervention arm will read about the Five-Factor model and receive a feedback report with individualized personality results and self-management recommendations.

The control arm will read about the Five-Factor model but will not receive feedback or their personality results until after the study.

The intervention is a personality feedback report that will tell participants whether they scored low (bottom third), average (middle third), or high (top third) on each of the five factor personality characteristics based on gender-matched norms. In addition to a description of general tendencies based on their level of each personality trait, the feedback will include information about how scoring in a given category may relate to an individual's cancer self-management or healthcare decision making. The feedback for each personality trait will include recommendations for how to improve key outcomes.

Participants' current state-level self-awareness will be assessed with a modified 6-item short form of the Reflective Self-Development subscale included in the Self-Awareness Outcomes Questionnaire (SAOQ). Participants rate each item from 1 to 5, and a total score will be calculated by summing participants responses to each item. The total score at each time point will range from 6 to 30, with higher scores indicating higher levels of self-awareness. The difference score from pre-intervention to post-intervention will be used in analyses, with higher scores indicating a greater increase in self-awareness.

Participants will respond to three 4-item custom short forms from the Patient-Reported Outcomes Measurement Information System (PROMIS) Self-efficacy for Managing Chronic Conditions Domain: 1) self-efficacy for managing emotions, 2) self-efficacy for managing symptoms, and 3) self-efficacy for managing medications and treatment. Each item is rated from 1 to 5, with raw scores on a summated total scale for each subscale ranging from 4 to 20. Each subscale's raw total score will be converted to a T-score, and a mean composite T-score across the 3 subscales will be calculated for each time point. Higher scores indicate higher levels of self-efficacy for managing their illness. For analyses, the difference in the mean T-score from pre-intervention to post-intervention will be computed, with higher scores indicating a greater increase in self-efficacy for managing their illness.
