Emotional and interpersonal states following dialectical behavioral therapy in adolescent borderline personality disorder: A proof-of-concept ecological momentary assessment outcome study

ABSTRACT Objective: The effects of Dialectical Behavioral Therapy for Adolescents (DBT-A) on emotional and interpersonal instability were explored in adolescents exhibiting Borderline Personality Disorder (BPD) features, using ecological momentary assessment (EMA) to reduce recall bias. Method: N = 28 help-seeking female adolescents were enrolled, meeting ≥ 3 DSM-IV BPD criteria. BPD criteria, non-suicidal self-injury (NSSI), and depressive symptoms were examined pre- and post-DBT-A treatment (mean duration: 42.74 weeks, SD = 7.46). Participants maintained e-diaries pre- and post-treatment, hourly rating momentary affect, attachment to mother and best friend, and self-injury urges. Results: Interview-rated BPD symptoms decreased (χ²(1) = 5.66, p = .017), alongside reduced self-rated depression severity (χ²(1) = 9.61, p = .002). EMA data showed decreased NSSI urges (χ²(1) = 9.05, p = .003) and increased mother attachment (χ²(1) = 6.03, p = .014). However, mean affect, affective instability, mean attachment to the best friend, and attachment instability showed no significant change over time. Conclusion: DBT-A yielded limited evidence for altering momentary affective states and instability in adolescents based on EMA. Nevertheless, significant effects were observed in reducing NSSI urges and enhancing interpersonal dynamics during treatment, as assessed via EMA.

Attentional Biases and Nonsuicidal Self-Injury Urges in Adolescents

Nonsuicidal self-injury (NSSI) is a significant clinical concern among adolescents. Exposure to NSSI-related content on social media platforms has been suspected to potentially act as a trigger for NSSI. To use free-viewing eye-tracking and dot-probe paradigms to examine attentional bias and psychophysiological responses to NSSI-related pictorial and textual stimuli in adolescents with and without a history of NSSI. From June 2022 to April 2023, adolescent participants in Vienna, Austria with and without a history of NSSI were exposed to NSSI-related stimuli in this nonrandomized controlled trial. Data were analyzed from December 2023 to January 2024. Exposure to NSSI-related stimuli. During both tasks, subjective arousal, NSSI urges, and autonomic nervous system activity were assessed. A total of 50 adolescents in 2 groups, 25 who engaged in NSSI (mean [SD] age 15.86 [1.14] years; 19 female participants [76%]) and 25 who did not (mean [SD] age 16.40 [1.71] years; 19 female participants [76%]) were included. Adolescents with a history of NSSI-but not those without a history of NSSI-showed a clear attentional bias toward NSSI-related images during eye-tracking, as indicated by increased initial fixations (500 ms stimulus presentation mean difference, 28.64%; 95% CI, 18.31%-38.98%; P < .001; 1000 ms stimulus presentation mean difference, 18.50%; 95% CI, 9.05%-27.95%; P < .001) and longer fixation durations (500 ms mean difference, 29.51 ms; 95% CI, 4.3-54.72 ms; P < .001; 1000 ms mean difference, 39.83 ms; 95% CI, 6.90-72.76 ms; P < .001), regardless of stimulus duration. This bias was associated with a heightened urge to engage in NSSI (d = 1.22; 95% CI, 0.69-1.73; P < .001), a trend not seen in adolescents without a history of NSSI. Similarly, in the dot-probe task, only the NSSI group showed an attentional bias toward NSSI images but not toward trauma images, emphasizing the specificity of their attentional bias. Physiological measures revealed no significant differences, suggesting that viewing NSSI images is not associated with increased autonomic arousal. Textual NSSI content did not provoke an attentional bias or heighten NSSI urges in either group. In this nonrandomized controlled trial of 50 adolescents, results highlighted a specific attentional bias toward NSSI-related pictorial stimuli in adolescents with a history of NSSI, particularly a difficulty in disengaging from NSSI images. These findings contribute to understanding maladaptive information processing in NSSI and suggest implications for clinical management and cognitive models addressing NSSI triggers.

Picturing self-harm: Investigating flash-forward mental imagery as a proximal and modifiable driver of non-suicidal self-injury.

Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk. An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days. Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge. Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.

A comparison of retrospectively reported and ecological momentary assessment-reported perceived social support in predicting ecological momentary assessment-reported non-suicidal self-injury.

Non-suicidal self-injury (NSSI) urges and behaviors are associated with lower perceived social support and related constructs (e.g., perceived rejection). However, no studies have examined the concordance of retrospective (baseline) and ecological momentary assessment (EMA) perceived social support assessments. Retrospective and EMA reports are often only weakly to moderately correlated; measurement approaches may, therefore, impact observed associations between variables. We tested whether average EMA-reported perceived emotional social support uniquely predicts EMA-reported NSSI urges and behaviors above baseline-reported retrospective self-report of perceived emotional social support alone. 93 young adults (ages 18-34) with past-month NSSI urges or behaviors and lifetime NSSI behaviors completed a semi-structured interview, self-report surveys, and a 2-week EMA protocol. Baseline- and EMA-reported perceived emotional social support were positively correlated (Kendall's tau-b = 0.51). Average EMA-reported social support was uniquely associated with EMA-reported NSSI urges but not NSSI behaviors. EMA-reported perceived emotional social support captured information not represented by baseline reports alone, but improvement in model fit was modest. EMA-reported social support may further improve the estimation of EMA-reported NSSI urges if modeled as a proximal predictor of NSSI. Further work is needed to clarify temporal directions between social support and NSSI urges. Limitations are discussed.

How does emotional abuse affect adolescents' non-suicidal self-injury urges? A moderated chain mediation model

BackgroundStudying non-suicidal self-injury (NSSI) among adolescents has high clinical significance. Its urges have been identified as a potential predictor of NSSI behavior and may serve as a crucial intervention target. ObjectiveThis study uses a moderated chain mediation model to explore the relationship between emotional abuse and adolescent NSSI urges. Additionally, we examine the mediating roles of ego depletion and self-esteem and the moderating effect of resilience. Participants and settingWe recruited 1129 Chinese adolescents (age M = 16.68; SD = 0.78; 49.4 % men) from secondary vocational schools in China. MethodsWe assessed emotional abuse, ego depletion, self-esteem, and NSSI urges in a longitudinal investigation across two time points (T1: March 2023, T2: June 2023). ResultsAfter controlling for age, sex, NSSI urges and self-esteem at T1, our study validates a moderated chain mediation model and finds that the mediating effect via self-esteem is 0.026 (95%CI = [0.011,0.046]), and the chain mediating effect via ego depletion and self-esteem is 0.031 (95%CI = [0.022,0.045]), whereas the direct effect of emotional abuse T1 on NSSI urges T2 is not significant (DE = 0.082, 95%CI = [−0.002, 0.167]) and the mediating effect via ego depletion is also not significant (IE = −0.003, 95%CI = [−0.022, 0.015]). Resilience moderates the impact of emotional abuse on ego depletion (β = 0.09, p < 0.01). ConclusionsThese findings suggest that ego depletion and self-esteem are potential mechanisms related to emotional abuse and adolescents' NSSI urges, whereas resilience can play a moderating role in reducing ego depletion.

Social stressors, emotional responses, and NSSI urges and behaviors in daily life

BackgroundThe defective self model of nonsuicidal self-injury (NSSI) theorizes that individuals who are highly self-critical are more likely to choose NSSI to regulate emotions. This model indirectly suggests that individuals who engage in NSSI may experience more self-conscious emotions in response to negative social feedback, increasing risk for near-term NSSI. This study examined (1) whether individuals with a history of NSSI (vs. without) display greater self-conscious and negative emotional reactions to daily social stressors, and more problematic features of these daily social stressors, and (2) whether greater-than-usual negative emotional reactions and social stressor features predict NSSI urges and behaviors in daily life. MethodsParticipants were 134 female college students with recent, recurrent NSSI (n = 77) or no NSSI history (n = 57). Participants completed baseline measures of socioemotional functioning and a two-week daily diary protocol. ResultsThe NSSI (vs. no NSSI) group reported significantly greater self-conscious and negative emotional reactions to daily social stressors, and social stressors characterized by greater dysfunction. In the NSSI group, experiencing social stressors characterized by greater distress than one's average during the daily diary period was associated with same-day NSSI urges and behavior, greater confusion than one's average predicted same-day NSSI urges, and greater conflict than one's average predicted same-day NSSI behavior. Greater self-conscious and negative emotional reactions to these stressors than one's average predicted same-day NSSI urges and behavior. LimitationsLimitations include reliance on self-report, a once-daily assessment, and lack of generalizability to other samples. ConclusionsInterpersonal conflict and increased self-conscious emotions pose vulnerability for NSSI. Prevention and intervention efforts would benefit from including a focus on interpersonal functioning.

Interpersonal stress and nonsuicidal self-injury disorder in veterans: An ecological momentary assessment study.

Nonsuicidal self-injury (NSSI) is associated with marked functional impairment and is a robust predictor of suicide attempts. Prevalence rates of NSSI, and self-directed violence more broadly, are elevated among military veterans. Despite the inclusion of interpersonal difficulty in the diagnostic criteria for NSSI disorder, the relationship between interpersonal risk factors and NSSI is not well-characterized, especially among veterans. This ecological momentary assessment (EMA) study investigated the hypothesis that interpersonal stressors and associated distress would precede and predict NSSI urge and engagement-but not vice versa-via cross-lagged multilevel modeling. Forty veterans with NSSI disorder completed a 28-day EMA protocol with three daily prompts assessing NSSI urges, NSSI engagement, the occurrence of interpersonal stressors, and associated subjective interpersonal distress. Interpersonal stressors preceded and predicted subsequent NSSI urges, but not NSSI engagement, whereas subjective interpersonal distress preceded and predicted both NSSI urges and NSSI engagement. Results identified interpersonal stressors as a risk factor for NSSI urges, and interpersonal distress as a risk factor for both NSSI urges and NSSI engagement. Findings highlight the importance of temporally assessing interpersonal factors related to NSSI and suggest that interpersonal distress may be a modifiable risk factor for NSSI.

How Technologies Can Support Self-Injury Self-Management: Perspectives of Young Adults With Lived Experience of Nonsuicidal Self-Injury.

BackgroundThere is growing interest in the design of digital interventions to improve conditions for young people who engage in high-risk behaviors, like nonsuicidal self-injury (NSSI). However, few studies have focused on how young people self-manage NSSI, or their existing, and historic, use of technologies to support their goals related to NSSI behavior change. Such an understanding has the potential to inform the design of digital interventions that meet this population's unique needs.ObjectivesThis study aims to (a) understand the self-management practices of young adults who engage in NSSI, (b) explore how they currently use technologies for self-injury self-management, and (c) identify the ways they can envision an app-based technology supporting their self-management.Methods and MaterialsTwenty young adults (aged 18–24) with lived experience of NSSI, and who were not currently enrolled in therapy, were recruited from online venues. Participants completed baseline measures to assess mental health and NSSI characteristics, followed by a virtual 1-h semi-structured interview where they were invited to share their experience of self-management, their goals, and their thoughts on supportive technology. Interview scripts were transcribed and analyzed via thematic analysis.ResultsThemes and sub-themes are organized under two broad domain areas: (1) How young adults self-manage NSSI thoughts and behaviors and (2) Opportunities and challenges for digital interventions to assist young adults in their recovery process. We found that young adults had varied experiences with, and goals related to, NSSI. Participants reported a lack of effective strategies to reduce NSSI urges and a desire for an app-based technology to track patterns and deliver personalized suggestions for self-management. Participants reported existing use of technologies as part of self-management, as well as early information and support seeking for NSSI online.ConclusionsThis study contributes a greater understanding of young people's experiences with self-injury, their self-management practices, and their desire to engage with technology. Our findings highlight the need for design flexibility in developing digital interventions that support individual goals, unique presentations of NSSI, and needs at different phases of recovery. Implications for the design of highly personalized and relevant digital interventions to address NSSI are discussed.

Risk management in dialectical behavior therapy: Treating life-threatening behaviors as problems to be solved.

Dialectical behavior therapy (DBT) is an empirically supported behavioral treatment for individuals with borderline personality disorder who frequently exhibit life-threatening behavior, such as suicide attempts, nonsuicidal self-injury urges and actions, and suicidal ideation. We provide an overview of the theoretical framework by which DBT conceptualizes these life-threatening behaviors and the principles by which safety planning measures are implemented and maintained throughout treatment. The importance of orienting clients to treatment and obtaining their commitment to decrease life-threatening behavior is reviewed. Relevant strategies associated with risk management and assessment, such as the diary card, chain analysis, solution analysis, phone coaching, and consultation team, are described. The overview concludes with a case example to illustrate the application of these techniques with a DBT client with a long-standing history of engaging in life-threatening behaviors.

Sleep irregularity and nonsuicidal self-injurious urges and behaviors.

The objectives of this study were to examine the relationships between sleep regularity and nonsuicidal self-injury (NSSI), including lifetime NSSI history and daily NSSI urges. Undergraduate students (N = 119; 18-26 years), approximately half of whom endorsed a lifetime history of repetitive NSSI, completed a 10-day actigraphy and ecological momentary assessment (EMA) protocol. A Sleep Regularity Index was calculated for all participants using scored epoch by epoch data to capture rapid changes in sleep schedules. Participants responded to EMA prompts assessing NSSI urge severity and negative affect three times daily over the 10-day assessment period. Results indicate that individuals with a repetitive NSSI history were more likely to experience sleep irregularity than those without a history of NSSI. Findings also suggest that sleep irregularity was associated with more intense urges to engage in NSSI on a daily basis, even after accounting for average daily sleep duration, sleep timing, negative affect, and NSSI history. Neither sleep duration nor sleep timing was associated with NSSI history nor daily NSSI urge intensity. Findings suggest that sleep irregularity is linked with NSSI, including NSSI history and intensity of urges to engage in NSSI. The present study not only supports the growing evidence linking sleep disturbance with the risk for self-injury but also demonstrates this relationship using actigraphy and real-time assessments of NSSI urge severity. Findings highlight the importance of delineating the nuances in sleep irregularity that are proximally associated with NSSI risk and identifying targets for intervention.

Affective states and nonsuicidal self-injury (NSSI): Results from an ecological momentary assessment study of veterans with NSSI disorder.

The affective states most strongly associated with nonsuicidal self-injury (NSSI) remain poorly understood, particularly among veterans. This study used ecological momentary assessment (EMA) to examine relationships between affect ratings and NSSI urges and behaviors among veterans with NSSI disorder. Participants (N=40) completed EMA entries via mobile phone for 28days (3722 total entries). Entries included intensity ratings for five basic affective states, as well as NSSI urges and behaviors, during the past 4hours. Bivariate analyses indicated that each affect variable was significantly associated with both NSSI urges and behaviors. Angry/hostile and sad were most strongly associated with both NSSI urges and behaviors. A multivariate regression revealed that angry/hostile, disgusted with self, and happy (inversely related) were contemporaneously (within the same period) associated with NSSI behaviors, whereas all five basic affective states were contemporaneously associated with NSSI urges. In a lagged model, angry/hostile and sad were associated with subsequent NSSI urges but not behaviors. Findings highlight the relevance of particular affective states to NSSI and the potential utility of targeting anger in treatments for NSSI among veterans. There is a need for future EMA research study to further investigate temporal relationships between these variables.

Examining momentary associations between behavioral approach system indices and nonsuicidal self-injury urges

BackgroundThe current study aimed to examine the concurrent and prospective relationships between the three hypothesized components of behavioral approach system (BAS) sensitivity: drive, reflecting the motivation to pursue one's desired goals; reward responsiveness, reflecting sensitivity to reward or reinforcement; and fun-seeking, reflecting the motivation for pursuing novel rewards in a spontaneous manner, and NSSI urge severity. MethodsA sample of 64 undergraduates with a history of repetitive NSSI completed an ecological momentary assessment protocol. During this period of time, participants reported on the BAS-constructs of drive, reward responsiveness, and fun-seeking, as well as NSSI urge severity on a momentary basis at three random intervals each day for a period of ten-days. ResultsDrive and reward responsiveness, but not fun-seeking, were concurrently positively associated with NSSI urge severity. However, no associations between BAS facets and prospective NSSI urges were found. LimitationsThis study was limited by its use of single items to assess the BAS-constructs of drive, reward responsiveness, and fun-seeking. ConclusionsOur findings indicate that feeling strongly impacted by rewards and having a strong sense of drive toward goal attainment may represent cognitive risk states that are associated with increased within-person NSSI risk. However, their lack of prospective prediction may suggest that these cognitive states are associated only on a momentary basis with NSSI urges and may not confer risk.

The Impact of Homeostatic and Circadian Sleep Processes on Non-Suicidal Self-Injury and Suicide Urges in Borderline Personality Disorder

Objective Borderline personality disorder (BPD) involves high rates of non-suicidal self-injury (NSSI) and suicidal behaviors, which are often preceded by urges. Disrupted sleep processes have been linked to NSSI and suicidal behaviors. However, it is unclear which specific sleep processes influence NSSI and suicide urges at rest (i.e., baseline) or in response to distress (i.e., reactivity) in BPD, and thus require targeting in BPD-specific interventions. This study examined whether two distinct homeostatic sleep processes (i.e., total sleep time [TST] and time in bed [TIB]), and one circadian sleep process (i.e., chronotype, or tendencies toward early versus late bed and rise times) predict baseline NSSI and suicide urges and urge reactivity in BPD. Methods Forty adults with BPD completed a seven-day sleep diary to measure average TST and TIB. They then completed a questionnaire to measure chronotype and underwent an experiment wherein they rated NSSI and suicide urges at baseline and following an emotion induction. Results Generalized estimating equations revealed that higher TST was associated with lower baseline NSSI urges, and lower suicide urge reactivity. Additionally, higher TIB predicted higher NSSI urge reactivity. Conclusions Sleep deprivation and extended time in bed may increase proclivity toward NSSI and/or suicide. Targeting these variables in BPD interventions may ultimately facilitate the reduction of NSSI and suicidal acts. Highlights Higher total sleep time predicts lower baseline NSSI urges, suicide urge reactivity Higher time in bed predicts higher NSSI urge reactivity Reducing sleep deprivation in BPD may facilitate reductions in suicide, NSSI urges

A test of the interpersonal function of non-suicidal self-injury in daily life

Theoretical models of non-suicidal self-injury (NSSI) posit that individuals use NSSI to influence others, but this remains largely untested. We used ambulatory assessment to test the interpersonal function of NSSI in the daily lives of 51 women with DSM-5 NSSI disorder. Participants reported NSSI events, urges, motives, and positive/negative interpersonal events (IPEs) for 14 days, providing five semi-random daily assessments and event-related NSSI reports. We analyzed 3,498 data-points, including 155 NSSI events, using multilevel models. We observed a positive concurrent association between the number of negative IPEs and NSSI engagement. Additionally, perceived distress of negative IPEs was positively associated with concurrent NSSI events and urges, and predicted later events. We saw no reduction in negative or increase in positive IPEs following NSSI. In a trait-level interview, participants endorsed interpersonal motives only minimally, but indicated that others often trigger NSSI. In daily life, participants rarely endorsed the motive ‘get help/attention’. The results suggest that negative IPEs trigger NSSI, but that individuals in this sample rarely used NSSI for interpersonal motives and did not experience interpersonal reinforcement of NSSI. We discuss limitations of and possible solutions for under-reporting of interpersonal motives and benefits of studying interpersonal triggers (rather than outcomes) in future studies.

Emotional response inhibition to self-harm stimuli interacts with momentary negative affect to predict nonsuicidal self-injury urges

The current study investigated whether impaired emotional response inhibition to self-harm stimuli is a risk factor for real-time nonsuicidal self-injury (NSSI) urges. Participants were 60 university students with a history of repetitive NSSI. At baseline, participants completed an emotional stop-signal task assessing response inhibition to self-harm stimuli. Participants subsequently completed an ecological momentary assessment protocol in which they reported negative affect, urgency, and NSSI urge intensity three times daily over a ten-day period. Impaired emotional response inhibition to self-harm stimuli did not evidence a main effect on the strength of momentary NSSI urges. However, emotional response inhibition to self-harm images interacted with momentary negative affect to predict the strength of real-time NSSI urges, after adjusting for emotional response inhibition to neutral images. Our findings suggest that emotional response inhibition deficits specifically to self-harm stimuli may pose vulnerability for increased NSSI urge intensity during real-time, state-level negative affect.

Anger precedes and predicts nonsuicidal self-injury in veterans: Findings from an ecological momentary assessment study

Veterans have high rates of suicide, and nonsuicidal self-injury (NSSI) is one of the strongest predictors of suicide risk; however, there is presently little known about antecedents of NSSI that might inform intervention efforts. Accumulating research suggests that anger and hostility play an important role in NSSI, but whether these emotions precede and predict NSSI is currently unknown. The aim of the current study was to examine the temporal relationships between anger/hostility and NSSI urges and behavior among veterans diagnosed with NSSI disorder. Our hypothesis was that angry/hostile affect would predict subsequent NSSI urge and engagement, but not vice versa. Forty veterans with NSSI disorder completed a 28-day ecological momentary assessment study with three daily prompts to report on their affect and NSSI urges and engagement. Multilevel cross-lagged path modeling was used to determine the direction of effects between angry/hostile affect and NSSI urges and engagement over time. Consistent with our hypothesis, results indicated that the lagged effects of angry/hostile affect on subsequent NSSI urge and engagement were significant, whereas the lagged effects of NSSI urge and engagement on angry/hostile affect were not significant. Findings highlight the importance of assessing and treating anger among veterans who engage in NSSI.

Salivary beta-endorphin in nonsuicidal self-injury: an ambulatory assessment study

Nonsuicidal self-injury (NSSI) is a prevalent and impairing behavior, affecting individuals with and without additional psychopathology. To shed further light on biological processes that precede and result from NSSI acts, we built on previous cross-sectional evidence suggesting that the endogenous opioid system, and especially β-endorphin, is involved in the psychopathology of NSSI. This is the first study assessing salivary β-endorphin in daily life in the context of NSSI acts. Fifty-one female adults with repetitive NSSI participated over a period of 15 days in an ambulatory assessment study. Salivary β-endorphin was assessed before and after engagement in NSSI, during high urge for NSSI, and on a non-NSSI day. Furthermore, NSSI specific variables such as pain ratings, as well as method, severity, and function of NSSI were assessed. We found that β-endorphin levels immediately before an NSSI act were significantly lower than directly after NSSI. However, there was no difference between β-endorphin during high urge for NSSI and post NSSI measures. We found a positive association between severity of the self-inflicted injury and β-endorphin levels, but no significant association between β-endorphin levels and subjectively experienced pain. The results of the present study indicate that it is possible to assess salivary β-endorphin in daily life in the context of NSSI. Furthermore, our results provide a first indication that NSSI acts could be associated with a momentary increase of β-endorphin, and this might reinforce NSSI engagement. More research is needed to replicate and extend our findings on peripheral β-endorphin in daily life.

The environmental, interpersonal, and affective context of nonsuicidal self-injury urges in daily life.

Urges for nonsuicidal self-injury (NSSI) are important precursors to NSSI acts and may serve as a point of intervention. A close understanding of the phenomenology of NSSI urges and the contexts in which they occur is therefore warranted. We used ambulatory assessment to examine the environmental, interpersonal, and affective contexts of NSSI urges. We recruited 56 participants with borderline personality disorder who reported on urges and contexts for 21 days with six random daily prompts, resulting in 5,750 completed assessments. Twenty-two participants reported 160 NSSI urges. We provide extensive descriptive results characterizing the interaction partners, activities, and events participants reported in association with NSSI urges. Results from a logistic multilevel model using the full sample (testing associations between all contexts and urges simultaneously) revealed that urges were more likely to occur at higher levels of negative affect, when rejection was experienced, and later in the day. Urges were not associated with disagreements or feeling let down, being at home versus away, being alone versus in company, socializing versus doing another activity, and it being a weekday versus weekend. Additional growth curve analysis for negative affect using the subsample of 22 participants who reported urges showed that, over the course of urge days compared with nonurge days, negative affect increased before urges, peaked during the urge, and then decreased, approximating a quadratic curve. We conclude that urges occurred primarily in the context of negative affect and rejection, which is consistent with theories on intra- and interpersonal functions of NSSI.

Real-time monitoring of the associations between self-critical and self-punishment cognitions and nonsuicidal self-injury

The Defective Self Model of nonsuicidal self-injury (NSSI) proposes that some people engage in NSSI to punish themselves and/or to respond to self-critical cognitions. Although there is a growing body of research to support this theory, there has been a lack of ecologically valid approaches employed to critically examine its tenets. The current study aimed to fill this gap in the literature. A sample of 64 undergraduates with a history of repetitive NSSI were recruited and completed an ecological momentary assessment (EMA) protocol. At baseline, participants completed trait measures of self-criticism and self-punishment cognitions. Over the EMA period, participants reported their experience of self-critical and self-punitive cognitions, and NSSI urge intensity three times daily. Our between-persons level findings suggest that trait and aggregated state self-punishment, but not self-critical cognitions, predict NSSI urges experienced over the EMA period. Our findings additionally provide evidence that both momentary self-critical and self-punishment cognitions are concomitantly and prospectively associated with NSSI urge intensity as measured in real-time and modeled at a within-persons level. However, after adjusting for concurrent NSSI urge intensity in prospective models, these within-persons level findings do not hold. Nevertheless, our findings provide greater support for the Defective Self Model of NSSI.

The role of reward sensitivity and childhood maltreatment in predicting nonsuicidal self-injury.

Findings from prior research on reward sensitivity in nonsuicidal self-injury (NSSI) have been mixed. Childhood maltreatment is an independent risk factor for NSSI and for hyposensitivity to rewards. This study aimed to disentangle the role of reward sensitivity as a predictor of NSSI for those with an elevated severity of childhood maltreatment. In a diverse undergraduate sample (N=586), trait reward sensitivity (i.e., behavioral approach system subscales) and the severity of maltreatment were assessed as predictors of a lifetime history of NSSI. In a subset of this sample (n=51), predictors of NSSI urge intensity were measured using ecological momentary assessment. Individuals with elevated maltreatment who reported less positive responsiveness to rewards were more likely to have a lifetime history of NSSI. Those with elevated maltreatment who reported a lower likelihood to approach rewards experienced more intense NSSI urges across the ten-day observation period. However, those with elevated maltreatment who reported a greater likelihood to approach rewards experienced less intense NSSI urges. The role of reward sensitivity as a cognitive risk factor for NSSI varies depending on childhood maltreatment history. Findings indicate that, for those with elevated maltreatment, hypersensitivity to approaching rewards may decrease risk for NSSI urges.
