Non-suicidal self-injury (NSSI), the deliberate and direct damage of one’s body tissue without suicidal intent, is a pervasive public health concern often leading to clinically significant long-term consequences (e.g., permanent scarring, hospitalization) that is theorized to be facilitated by negative affect and emotion dysregulation. The Emotional Cascade Model proposes that NSSI partially functions to disrupt the reciprocal and rapid amplification of negative affect driven by rumination. However, limited research has focused on state rumination and the distinct contribution of maladaptive and adaptive rumination subtypes, as well as the role of positive affect within this framework. Thus, the purpose of the current study was to replicate and explore the independent influences of overall and momentary (1) positive and negative affect and (2) rumination on NSSI acts and urges, as well as (3) the extent to which rumination moderates the relationship between affect and NSSI. To do so, rumination, affect, and NSSI urges and acts were assessed 4 times daily via ecological momentary assessment for 21-days among thirty undergraduate participants with past month NSSI. Our results partially replicated existing literature, such that overall negative affect was associated with greater overall NSSI urge strength and momentary negative affect and rumination predicted stronger NSSI urges at the next alert, with increased momentary rumination strengthening the relationship between momentary negative affect and NSSI urge. Exploratory investigations of overall and momentary positive affect showed some negative associations with NSSI urges and behaviors, with no moderating effect of rumination. Data did not support the independent examination of maladaptive and adaptive rumination subtypes. Taken together, this study highlighted the importance of exploring state rumination (in addition to trait) and affect in understanding NSSI thoughts and behaviors, and calls for future studies to further investigate distinct properties of rumination to understand its impact on specific emotions that maintain NSSI engagement. / Psychology
