“…Similarly, sensation‐seeking items refer to engaging in extreme actions or generating physiological arousal (e.g., “rush/excitement”). The physical and immediate nature of these effects is more likely to be achieved through NSSI acts because of the injuries produced and the subsequent physiological effects (Liu, ); whereas the physical effects of most ED behaviors are vague or accumulated over time. Similarly, NSSI behaviors hold a closer approximation to suicidal acts than do ED behaviors.…”

Objective This study examined whether the psychological functions motivating eating disorder (ED) and nonsuicidal self‐injury (NSSI) behaviors are similar, thereby representing shared mechanisms accounting for their high co‐occurrence. Method Self‐report data assessing NSSI, ED symptoms, and behavioral functions were collected from 676 adults with recent NSSI (past 6 months; n = 333) or disordered eating ( n = 343). Results Measurement invariance analyses revealed the same function‐factor structure for ED and NSSI behaviors for 8 out of 13 scales. Comparisons of scalar latent means showed that some functions, while relevant to both behaviors, were rated as subjectively more salient to engaging in either ED or NSSI behavior. Conclusions Similar functions have relevance to understanding engagement in NSSI and ED, but important differences exist in the subjective salience of each function. Treatments focusing on the shared functions of NSSI and ED may have greater success in simultaneously decreasing engagement in these behaviors.

“…Although SI and NSSI typically emerge during adolescence (2,5) and often co-occur (6,7), researchers and clinicians have long recognized that these phenomena are distinct (8,9) and likely have unique neurobiological substrates (10,11). Thus, elucidating the specific neurobiological patterns that characterize SI and NSSI in adolescents may shed insight into the diverse etiology of these behaviors, help to refine brain-based conceptual models (12,11), and identify neural circuits that are sufficiently sensitive to assess the efficacy of targeted interventions (13).…”

Suicidal ideation (SI) and non-suicidal self-injury (NSSI) are two distinct yet often co-occurring risk factors for suicide in adolescents. Elucidating the neurobiological patterns that specifically characterize SI and NSSI in adolescents is needed to inform the use of these markers in intervention studies and to develop brain-based treatment targets. Here, we clinically assessed 70 adolescents—49 adolescents with depression and 21 healthy controls—to determine SI and NSSI history. Twenty-eight of the depressed adolescents had a history of SI and 29 had a history of NSSI (20 overlapping). All participants underwent a resting-state fMRI scan. We compared groups in network coherence of subdivisions of the central executive network (CEN), default mode network (DMN), and salience network (SN). We also examined group differences in between-network connectivity and explored brain-behavior correlations. Depressed adolescents with SI and with NSSI had lower coherence in the ventral DMN compared to those without SI or NSSI, respectively, and healthy controls (all ps<0.043). Depressed adolescents with NSSI had lower coherence in the anterior DMN and in insula-SN (all ps<0.030), and higher CEN–DMN connectivity compared to those without NSSI and healthy controls (all ps<0.030). Lower network coherence in all DMN subnetworks and insula-SN were associated with higher SI and NSSI (all ps<0.001). Thus, SI and NSSI are related to brain networks associated with difficulties in self-referential processing and future planning, while NSSI specifically is related to brain networks associated with disruptions in interoceptive awareness. Intrinsic network patterns may be reliable biomarkers of SI and NSSI in adolescents.

“…These findings illustrate the importance of integrating data from performance-based tasks with self-report data when assessing the complex processes that maintain NSSI (Bentley, Nock, & Barlow, 2014;Liu, 2017). Employing performance-based tasks to measure implicit cognitive processes, such as the NSSI attentional bias exhibited by participants in this sample, may help address the incongruence that can occur between self-reported versus behavioral measures of the contingencies reinforcing NSSI.…”

Nonsuicidal self-injury (NSSI) is a prevalent behavior among young people maintained by complex transdiagnostic processes. This study sought to investigate whether NSSI attentional bias-the preferential allocation of attentional resources to environmental NSSI cues-is one such transdiagnostic process experienced by young adults with histories of NSSI. Participants were 39 young adults who completed a dot probe task designed to measure attentional bias to NSSI cues and negatively-valenced cues. Participants also provided NSSI urge and affect ratings during the task. Paired samples t-tests were conducted to determine if participants exhibited a significant attentional bias to NSSI cues and negatively-valenced cues compared to neutral cues, and to test whether NSSI urge ratings following the dot probe task increased from baseline levels. Participants exhibited a significant attentional bias to NSSI cues presented for 200 ms and a significant attentional bias to negative cues presented for 200 ms. The urge to engage in NSSI was elicited by NSSI cues, but not by negative cues. These findings indicate exposure to NSSI cues elicits both attentional bias and NSSI urge, a unique process that differs from a mere generalized attentional bias to negative affective stimuli known to be exhibited by individuals with other forms of psychopathology, such as anxiety or depressive disorders. These results provide preliminary evidence for possible avenues of intervention as it relates to the role of exposure to NSSI cues in the maintenance of NSSI, including managing cue-elicited urge and tolerating changes in affective states.
