To investigate low point autobiographical narratives among cancer survivors and romantic partners. Cancer survivors (Study 1) and romantic partners (Study 2) narrated the low points of their cancer experiences. Partners also narrated stories of cancer survivors' low points. Narratives were coded for their manifest content, as well as redemption (negative-to-positive arc), contamination (positive-to-negative arc), and tone (positive or negative valence). Self-reported measures of health and well-being (life satisfaction, cancer-related worry, impact of cancer). The diagnosis moment was the most frequently recognised low point among survivors and partners. Survivors who narrated contaminated low points reported marginally less somatisation, salience of cancer recurrence, and that cancer had a marginally less positive impact, relative to survivors whose narratives did not contain contamination. Tone in partners' low points predicted marginally less worry and more somatisation. The tone of their vicarious low points negatively correlated with anxiety. This research contributes to the growing body of work examining, and giving voice to, the experiences of cancer survivors and those close to them. As such, it informs applied health researchers of potentially challenging cancer-related experiences, and the way(s) in which the storying of these experiences align with psychological flourishing.
