Nonsuicidal Self-Injury and Affect Regulation: Recent Findings From Experimental and Ecological Momentary Assessment Studies and Future Directions

Non-Suicidal Self-Injury and Emotional Dysregulation in Male and Female Young Adults: A Qualitative Study

Objectives

Non-suicidal self-injury (NSSI) has been theoretically, clinically, and empirically associated with emotional dysregulation. NSSI is a means of regulating emotional states, particularly negative emotions. However, empirical studies on this topic are scarce and the literature lacks qualitative research on individuals' perceptions and comprehension of the function of self-injury. Thus, this qualitative study aimed to provide novel insights into the relationship between NSSI and emotional dysregulation in young adults.

Methods

Twelve participants (mean age=22.7 years, 9 females and 3 males) from different support groups and a healthcare center participated in semi-structured interviews on NSSI-related emotional processes. Three aspects were investigated: reasons for NSSI, function of NSSI, and emotions. Each interview was voice recorded and typically lasted between 20 and 40 minutes. All responses were analyzed using thematic analysis.

Results

Four major themes were identified. The results showed that NSSI had both intrapersonal and interpersonal functions, within which emotional regulation played a significant role. NSSI was also used to regulate positive emotions. The results also showed a sequence of emotions among the participants, going from feeling overwhelmed to feeling relatively calm but guilty.

Conclusion

NSSI has several functions for the same individual. Thus, it would be interesting to provide integrative therapy, such as emotion-focused therapy, which focus on improving intrapersonal and interpersonal emotion regulation skills and strategies.

A meta-analysis on the affect regulation function of real-time self-injurious thoughts and behaviours

Prominent theories suggest that self-injurious thoughts and behaviours are negatively reinforced by decreased negative affect. The present meta-analysis quantifies effects from intensive longitudinal studies measuring negative affect and self-injurious thoughts and behaviours. We obtained data from 38 of the 79 studies (48%, 22 unique datasets) involving N = 1,644 participants (80% female, 75% white). Individual-participant data meta-analyses revealed changes in affect pre/post self-injurious thoughts and behaviours. In antecedent models, results supported increased negative affect before nonsuicidal self-injurious behaviour (k = 14, 95% CI 0.09 to 0.31) and suicidal thoughts (k = 14, 95% CI 0.03 to 0.19). For consequence models, negative affect was reduced following nonsuicidal self-injurious thoughts (k = 6, 95% CI -0.79 to -0.44), nonsuicidal self-injurious behaviours (k = 14, 95% CI -0.73 to -0.19) and suicidal thoughts (k = 13, 95% CI -0.79 to -0.23). Findings, which were not moderated by sampling strategies or sample composition, support the affect regulation function of self-injurious thoughts and behaviours.

Emotional Reactivity and Inhibitory Control in Nonsuicidal Self-Injury Adolescence: Divergence Between Positive and Negative Emotions

Nonsuicidal self-injury (NSSI) is prevalent in adolescents and is often linked to emotion dysregulation. However, it remains unknown which specific processes of emotion regulation and under what emotional context these processes are related to the risk for NSSI in samples of community-based adolescents. This study used two laboratory tasks to examine whether adolescents with a history of NSSI displayed difficulties in emotional reactivity and inhibitory control in response to negative and positive emotions. In Study 1, adolescents with/without a history of NSSI (N = 64; M_Age = 13.45 ± 0.50; 53% female) completed a picture perception task in which they were asked to judge the valence and arousal of images. In Study 2, adolescents with/without a history of NSSI (N = 74; M_Age = 13.49 ± 0.80; 50% female) were given a two-choice emotional oddball task that required them to differentially respond to frequent stimuli (images of an object) and infrequent stimuli (affective images). The results showed that adolescents with a history of NSSI showed decreased emotional sensitivity and lower levels of inhibitory control in response to images depicting negative emotional content but not to those depicting positive emotional content. Furthermore, affective inhibitory control problems were significantly positively related to the severity of NSSI, especially in the context of negative emotions. These findings suggest that there is a divergence between positive and negative emotions in both emotional reactivity and affective inhibitory control processes on NSSI. Specifically, relative to adolescents with no history of NSSI, adolescents with a history of NSSI showed lower emotional awareness and behavioral inhibitory control when processing negative emotions, but these distinctions were not found in contexts involving positive emotions. Additionally, the results suggest that affective inhibitory control deficits specific for negative emotions may result in vulnerability to increased NSSI severity.

Borderline personality disorder symptoms as mediational mechanisms linking childhood trauma and nonsuicidal self-injury among women with bulimia nervosa

OBJECTIVE

Nonsuicidal self-injury (NSSI) frequently co-occurs with eating disorders, especially bulimia nervosa (BN). Theoretical models and empirical evidence show many overlapping risk factors for the onset and maintenance of NSSI and BN. However, among those with BN, it remains unclear what distinguishes those who do versus do not engage in NSSI. The primary objective of the present study was to identify factors predicting NSSI among women with BN. Specifically, we tested four domains of borderline personality disorder as mediators between childhood trauma and NSSI.

METHOD

Using structural equation modeling we tested a parallel mediation model to predict NSSI among women with BN (N = 130). Childhood trauma (measured by the Childhood Trauma Questionnaire at baseline) was the independent variable. The four parallel mediators (measured at baseline via the Diagnostic Interview for Borderlines, Revised) were lifetime negative affect, impulsive actions, atypical cognitions (e.g., odd thinking, unusual perceptual experiences, quasi-psychotic thinking), and interpersonal problems. The dependent variable was instances of NSSI during a subsequent two-week ecological momentary assessment protocol.

RESULTS

Childhood trauma was significantly associated with all four mediators (all p values < .01), but only atypical cognitions predicted NSSI (p = .03). The indirect path from childhood trauma to NSSI, through atypical cognitions was significant (path coefficient = .001, SE < .001, p = .01).

DISCUSSION

Among women with BN, childhood trauma was associated with atypical cognitions, which in turn predicted NSSI. Atypical cognitions may be a mechanism for NSSI in this population.

Variability in the Functions of Nonsuicidal Self-Injury: Evidence From Three Real-Time Monitoring Studies

Despite functional models of nonsuicidal self-injury (NSSI) helping to explain why people engage in this perplexing behavior, we still lack an understanding of some of the key properties of NSSI functions. Here, we address three unanswered questions about NSSI functions: how much do distinct NSSI functions (1) vary between people over time, (2) vary within people over time, and (3) simultaneously co-occur over time? Data were drawn from three ecological momentary assessment (EMA) studies of self-injurious adult psychiatric outpatients (n = 7), community-based adolescents (n = 15), and community-based adults (n = 9). Across the three studies, there was a total of 271 NSSI episodes (all with corresponding functions captured by EMA). The vast majority (27 of 31; 87%) of participants exhibited unique patterns of NSSI functions during the monitoring periods, indicating high variability between people. The vast majority (26 of 31; 84%) of participants also showed changes in NSSI functions over time, indicating high variability within people. Although it was most common for only one function to be reported for a given NSSI episode, participants endorsed more than one function for 22% to 43% of NSSI episodes, indicating that different functions did simultaneously co-occur. These results underscore that reinforcement processes for NSSI differ from person-to-person, and are both time-varying and multifaceted, which has implications for personalized assessment and treatment of this clinical phenomenon.

Emotion regulation deficits across the spectrum of self-harm

Suicide and non-suicidal self-injury (NSSI) are prevalent in emerging adulthood and one possible commonality is emotion regulation deficits. Participants (N = 708) completed multiple self-report measures that assessed emotion regulation deficits, depression, past-year NSSI frequency, past-year suicide attempts, and recent suicide ideation severity. Controlling for depression, linear regression analyses found that the only significant association was between greater deficits in emotion regulation strategies and greater recent NSSI frequency and suicide ideation intensity. These results suggest some commonality in emotion regulation deficits across NSSI and suicide ideation. Prevention and intervention efforts should teach emotion regulation strategies to lower self-harm risk.

Predicting Non-Suicidal Self-Injury in Young Adults with and without Borderline Personality Disorder: a Multilevel Approach Combining Ecological Momentary Assessment and Self-Report Measures

Non-suicidal self-injury (NSSI) is an increasingly prevalent phenomenon associated with many detrimental outcomes, ranging from poor academic performance to suicide attempts. Research on self-harming behaviors has identified emotion dysregulation, negative affect, and borderline pathology as strong risk factors of NSSI, whereas the potential protective effects of metacognitive skills such as decentering have not yet been explored. The current study combined ecological momentary assessment (EMA) and self-report measures to explore potential risk and protective factors of NSSI in a clinical group of Borderline Personality Disorder (BPD) patients with NSSI (N = 22), a subclinical group of college students with NSSI (N = 19), and a non-clinical healthy control group (N = 23). Participants completed self-report measures of borderline pathology, emotion dysregulation, decentering ability, and negative emotional symptoms, and they used the Sinjur App (EMA instrument) at least three times a day for 15 days to capture negative affect and NSSI in daily life. A multilevel mixed-effect regression analysis with both self-report and EMA measures was conducted to identify predictors of NSSI. The multilevel analysis showed that only momentary frustration directly predicted NSSI. Momentary guilt and anger only predicted NSSI when interacting with more stable traits of borderline pathology and negative emotional symptoms. Most importantly, greater decentering capacity protected against self-injury and attenuated the association between momentary sadness and NSSI. Findings contribute novel knowledge about NSSI, documenting the protective effects of decentering and highlighting the benefit of interventions that target metacognitive emotion regulation skills.

Nonsuicidal Self-injury, Suicide Planning, and Suicide Attempts Among High-risk Adolescents Prior to Psychiatric Hospitalization

The purpose of this study was to understand the trajectories of nonsuicidal self-injury (NSSI) and suicide plans (SP) in the 90 days prior to inpatient hospitalization, understand the role of NSSI and SP in predicting suicide attempts (SA) on a given day, and to test the interaction between NSSI and SP in predicting same-day SA. Participants included 69 adolescents (77% female, 65% white, 77% Non-Hispanic/Latinx, M_age = 15.77 SD_age = 1.00) from an inpatient psychiatric unit. Past 90 day NSSI, SP, and SA were measured using the Columbia Suicide Severity Rating Scale and Timeline Follow Back. First, mixed effect models were conducted to assess trajectories of NSSI and SP leading up to inpatient hospitalization. The odds of NSSI remained relatively stable prior to hospitalization (OR = 1.01, 95% CI [1.00,1.02]). The odds of SP increased in the 90 days prior to hospitalization (OR = 1.04, 95% CI [1.02,1.05]) with each day associated with a 4% increase in the odds of making a SP. Second, random effect models were conducted to predict the odds of same-day SA from NSSI and SP. When adolescents endorsed either NSSI (OR = 2.99, p < .001) or a SP (OR = 77.13, p < .001) there was elevated odds of same-day SA. However, the presence of both NSSI and SP on a given day did not increase risk of SA on that same day. For this high-risk clinical sample of suicidal adolescents who drink alcohol, odds of SP increased in the days leading up to psychiatric hospitalization, but NSSI remained stable. On days when adolescents reported NSSI or SP, they had an increased odds of same-day SA. These results underscore the importance of frequent monitoring of NSSI and SP among high-risk adolescents who drink alcohol to prevent suicide attempts.

Stressful Experiences in University Predict Non-suicidal Self-Injury Through Emotional Reactivity

Theoretical perspectives on non-suicidal self-injury (NSSI; direct and deliberate self-injury without lethal intent such as self-cutting or hitting) have long underscored the affective regulating properties of NSSI. Less attention has been given to the processes through which individuals choose to engage in NSSI, specifically, to regulate their distress. In the present study, we tested one theoretical model in which recent stressful experiences facilitates NSSI through emotional reactivity. Further, we tested whether the indirect link between stressful experiences and NSSI was moderated by several NSSI specific risk factors (e.g., having friends who engage in NSSI). Given the widespread prevalence of NSSI among community-based samples of adolescents and emerging adults, we surveyed 1,125 emerging adults in first-year university at a large academic institution (72% female, Mage = 17.96, 25% with a recent history of NSSI at Time 1). Participants completed an online survey three times (assessments were 4 months apart), reporting on their recent stressful experiences in university, emotional reactivity, NSSI, as well as three NSSI specific risk factors (i.e., close friend engagement in NSSI, high self-disgust, and low fear of pain). As expected, path analysis revealed that there was a significant indirect effect of recent stressful experiences on NSSI engagement, through emotional reactivity. However, this effect was maintained across moderator analyses. These novel findings underscore the salient role of proximally occurring stressors in the prediction of NSSI among emerging adults in university, and can inform developing theoretical perspectives on NSSI.

Profiles of Emotion Dysregulation Among University Students Who Self-Injure: Associations with Parent-Child Relationships and Non-Suicidal Self-Injury Characteristics

More research is needed to understand the different vulnerability profiles of university students who engage in non-suicidal self-injury (NSSI). This study sought to classify university students (n = 479; 83.8% female) aged 17-25 years (M = 18.77; SD = 1.42) who had engaged in NSSI within the past year into latent profiles based on their self-perceived difficulties in regulating both positive and negative emotions. Independent samples of students who had a past history of NSSI but had not self-injured within the previous year (n = 439; 82.9% females; M_age = 19.03, SD = 1.62) and who had no history of NSSI (n = 1551; 69.9% females; M_age = 19.02, SD = 1.55) were recruited for comparison purposes. Latent cluster analyses revealed three emotion regulation profiles within the NSSI sample-the Average Difficulties (47.4%), Dysregulated (33.0%), and Low Difficulties (19.6%) profiles-each of which differed meaningfully from both comparison samples on mean emotion regulation difficulties. Students across profiles also differed in their self-reported experiences with parents, particularly with fathers (pressure, antipathy, unresolved attachment, psychological control), and in the extent to which they felt alienated from parents. Lastly, students across profiles differed in the frequency, methods, functions, and addictive properties of their NSSI. Findings highlight that university students who self-injure experience distinct patterns of difficulties with emotion regulation, which are associated with variation in parent-child relational risk factors and NSSI outcomes.

Emotion Reactivity and Suicide Risk in Patients With Depression: The Mediating Role of Non-Suicidal Self-Injury and Moderating Role of Childhood Neglect

Background: The association between emotion reactivity (ER) and suicide risk has been confirmed in recent studies, especially in patients with depression. However, there is a lack of understanding of the underlying mechanism of the relation from ER to suicide risk among patients with depression. This study planned to examine a model of how ER, non-suicidal self-injury (NSSI), and childhood neglect (CN) interact to affect suicide risk in depressed patients. Methods: Four hundred and ninety-six patients (64.5% female, mean age = 30.40 years, SD = 12.56) who have accomplished self-rating instruments of ER, NSSI, CN, and suicide risk were included. Results: Findings showed that ER was positively connected with suicide risk, and NSSI partially mediated the above connection. Besides, CN moderated the mediation model, that is, the mediation effect was more pronounced in depressed patients with CN compared to depressed patients without CN. Conclusions: It was concluded that there is a relationship among ER, NSSI, CN, and suicide risk in patients with depression, and it strengthens our knowledge of the mechanism behind suicide risk. Our findings emphasize that the identification of NSSI and CN should be considered when assessing the suicide risk of patients with depression, as well as the intervention focus on emotion regulation and support for patients.

Predicting engagement in nonsuicidal self-injury (NSSI) over the course of 12 months: the roles of borderline personality disorder pathology and emotional consequences of NSSI

BACKGROUND

Despite theories that negative reinforcement in the form of relief from negative emotions maintains nonsuicidal self-injury (NSSI), no studies have examined the extent to which specific emotional consequences of NSSI predict the maintenance of NSSI over time or explain the greater risk for NSSI found among individuals with borderline personality disorder (BPD) pathology. This study examined whether specific emotional consequences of NSSI relate to the continuance of NSSI behavior over a 12-month period and explain the relation of baseline BPD pathology to future NSSI.

METHODS

Participants with a history of recent repeated NSSI (N = 84) completed baseline measures of BPD pathology, NSSI, and the emotional antecedents and consequences of NSSI, including self-conscious emotions, undifferentiated negative affect, anger, emptiness, sadness, and anxiety; follow-up data on NSSI were collected every three months for one year.

RESULTS

Of the emotional consequences of NSSI examined here, only self-conscious emotions significantly predicted the presence and frequency of NSSI during the 12-month follow-up period. Likewise, whereas BPD pathology was not directly associated with later NSSI, both overall BPD pathology and the specific BPD feature of identity problems were indirectly related to the presence of 12-month NSSI through the greater frequency of post-NSSI self-conscious emotions.

LIMITATIONS

Emotional consequences of NSSI were assessed using a retrospective self-report measure. Only frequency, and not intensity, of emotions before and after NSSI were assessed.

CONCLUSIONS

Results suggest a distinct role of post-NSSI self-conscious emotions in the maintenance of NSSI among individuals with and without BPD pathology.

Suicidal thoughts, suicidal behaviours and self-harm in daily life: A systematic review of ecological momentary assessment studies

Background

Ecological Momentary Assessments (EMA) offer an approach to understand the daily risk factors of suicide and self-harm of individuals through the use of self-monitoring techniques using mobile technologies.

Objectives

This systematic review aimed to examine the results of studies on suicidality risk factors and self-harm that used Ecological Momentary Assessments.

Methods

Pubmed and PsycINFO databases were searched up to April 2020. Bibliographies of eligible studies were hand-searched, and 744 abstracts were screened and double-coded for inclusion.

Results

The 49 studies using EMA included in the review found associations between daily affect, rumination and interpersonal interactions and daily non-suicidal self-injury (NSSI). Studies also found associations between daily negative affect and positive affect, social support, sleep, and emotions and a person's history of suicide and self-harm. Associations between daily suicide thoughts and self-harm, and psychopathology factors measured at baseline were also observed.

Conclusions

Research using EMA has the potential to offer clinicians the ability to understand the daily predictors, or risk factors, of suicide and self-harm. However, there are no clear reporting standards for EMA studies on risk factors for suicide. Further research should utilise longitudinal study designs, harmonise datasets and use machine learning techniques to identify patterns of proximal risk factors for suicide behaviours.

A systematic review of daily life studies on non-suicidal self-injury based on the four-function model

Non-suicidal self-injury (NSSI) is a prevalent, impairing, and trans-diagnostic behavior that can be comprehensively assessed in daily life studies. We conducted a systematic literature review of 35 Ambulatory Assessment and Daily Diary studies of NSSI, to achieve three aims. First, we reviewed descriptive evidence on NSSI acts. On average, studies observed 1.6 acts per participant, but evidence regarding methods, pain, and context was sparse. Second, we reviewed evidence on NSSI urges. On average, studies reported 4.3 urges per participant. Urges were also associated with increased negative affect and predicted later acts. Third, we reviewed evidence on the Four-function Model of NSSI. Eight studies partially supported negative intrapersonal reinforcement, showing increased negative affect pre NSSI, but, of these, only four studies supported decreased negative affect post NSSI. Additionally, only three studies supported positive intrapersonal reinforcement, showing decreased positive affect pre and increased positive affect post NSSI. Evidence for the interpersonal functions was limited to two studies and inconclusive. We recommend assessing the intensity, frequency, and context of acts and urges, as well as pain and urge duration in future studies. We also recommend follow-up prompts after acts and urges to better track affect trajectories, and a detailed assessment of interpersonal events.

Emotional Response Inhibition: A Shared Neurocognitive Deficit in Eating Disorder Symptoms and Nonsuicidal Self-Injury

Eating disorder (ED) symptoms often co-occur with non-suicidal self-injury (NSSI). This comorbidity is consistent with evidence that trait negative urgency increases risk for both of these phenomena. We previously found that impaired late-stage negative emotional response inhibition (i.e., negative emotional action termination or NEAT) might represent a neurocognitive mechanism for heightened negative urgency among people with NSSI history. The current study evaluated whether relations between negative urgency and ED symptoms similarly reflect deficits in this neurocognitive process. A total of 105 community adults completed an assessment of ED symptoms, negative urgency, and an emotional response inhibition task. Results indicated that, contrary to predictions, negative urgency and NEAT contributed independent variance to the prediction of ED symptoms, while controlling for demographic covariates and NSSI history. Worse NEAT was also uniquely associated with restrictive eating, after accounting for negative urgency. Our findings suggest that difficulty inhibiting ongoing motor responses triggered by negative emotional reactions (i.e., NEAT) may be a shared neurocognitive characteristic of ED symptoms and NSSI. However, negative urgency and NEAT dysfunction capture separate variance in the prediction of ED-related cognitions and behaviors, distinct from the pattern of results we previously observed in NSSI.

Invalidating Caregiving Environments, Specific Emotion Regulation Deficits, and Non-suicidal Self-injury

This study examined the indirect effects of distinct aspects of invalidating caregiving environments (i.e., paternal maltreatment, maternal maltreatment, and perceived alienation) on non-suicidal self-injury (NSSI) via six specific emotion regulation difficulties. We hypothesized that specific emotion regulation deficits would mediate associations between invalidating environments and NSSI. Participants included 114 young adults (57 self-injurers; 57 age- and sex-matched comparison participants) aged 17-25 years. Three parallel mediation models tested hypotheses. Results showed that maternal maltreatment, paternal maltreatment, and perceived alienation indirectly predicted NSSI through poor emotional clarity. Maternal maltreatment uniquely predicted NSSI through limited access to regulation strategies. Lastly, maternal maltreatment and perceived alienation were both linked to greater difficulties engaging in goal-directed behavior during emotional upsets; however, contrary to hypotheses, this particular deficit was associated with decreased odds of engaging in NSSI. Findings illustrate how different aspects of invalidating environments and specific emotion regulation deficits may be implicated in NSSI engagement.

Ecological momentary assessments among patients with cancer: A scoping review

Introduction

Ecological momentary assessment (EMA) is an emerging method to assess an individual's current thoughts, affect, behaviour, physical states and contextual factors as they occur in real‐time and in their natural environment. Whereas EMA is frequently used in mental health, little is known about the added value of EMA in oncology research. This review aimed to synthesise methodological information and results of studies that applied EMA among patients with cancer to inform future researchers about the opportunities and challenges.

Methods

We included full‐text articles on studies that: (a) were conducted among adult cancer patients; and (b) examined cancer and treatment‐related experiences by EMA. Information from selected studies was synthesised: study designs, EMA data collection methods, response‐related results and main findings.

Results

Twelve studies were included, which all applied an observational design. The EMA data collection methods varied considerably and the reporting of response‐related results were poor. Nevertheless, EMA was found feasible as no systematic patterns of problems were reported and reported response‐related results were acceptable. Furthermore, EMA was found useful as it facilitated examination of real‐time experiences and behaviour.

Conclusion

Ecological momentary assessment is useful and feasible in oncology research. Future studies would benefit from guidelines for designing and reporting EMA studies.

Applying a cognitive-emotional model to nonsuicidal self-injury

The recently proposed cognitive-emotional model of nonsuicidal self-injury (NSSI) draws on emotion regulation models and social cognitive theory to understand the onset, maintenance, and cessation of NSSI. We tested the prediction of the model that the relationship between emotional reactivity and NSSI is moderated by specific cognitions about self-injury (i.e., self-efficacy to resist NSSI, NSSI outcome expectancies), emotion regulation, and rumination. A sample of 647 university students aged 17-25 years (M = 19.92, SD = 1.78) completed self-report measures of the constructs of interest. As expected, we found that emotional reactivity was positively related to NSSI, particularly for people who had weak self-efficacy to resist NSSI. However, emotional reactivity was negatively related to NSSI for people who were more likely to use expressive suppression to regulate emotion. Implications for the theoretical understanding of NSSI are discussed.

A lab-based study exploring the associations among nonsuicidal self-injury, pain, and emotion among university students

Nonsuicidal self-injury (NSSI; e.g., self-cutting without lethal intent) is a widespread mental health concern among emerging adults in university. Although accumulating evidence suggests that NSSI is primarily an emotion coping behaviour, little is known about variability in emotional response to pain among individuals who self-injure. Recent theory on NSSI suggests that individuals who engage in NSSI to self-punish may experience additional affective gains in response to pain compared to individuals without self-punishment motivations for NSSI and individuals who do not self-injure. To test this hypothesis, 82 undergraduate students (Mage = 21.52 years) were recruited from a mid-sized university, and reported on their emotions three times: at baseline, following a stress-induction task, and after a cold-pressor task. Although all participants showed decreased negative emotions (e.g., hostility, fear) and increased serenity following cold pain, students who engaged in NSSI specifically to self-punish also showed decreased guilt and sadness. The present findings demonstrate that pain may serve to regulate different emotions for students who self-injure depending on their motivations for engaging in NSSI. Additionally, findings suggest that prevention and intervention efforts aimed at reducing the need to self-punish may help to reduce some of the emotionally reinforcing properties of NSSI.

Perceived effectiveness of NSSI in achieving functions on severity and suicide risk

Nonsuicidal self-injury (NSSI) continues to be a psychiatric problem for youth and young adults, and is a robust risk factor for suicidal thoughts and behaviors. Research has established that NSSI is motivated by intrapersonal and interpersonal functions; however, research on the perceived effectiveness of NSSI for achieving the desired functions is lacking. In the current study, it was expected that using NSSI to achieve intrapersonal functions would be rated as more effective than interpersonal functions, and that perceived effectiveness of NSSI would be differentially related to NSSI severity and suicide risk outcomes. In a sample of 264 adults with lifetime NSSI history (over 70% past year), intrapersonal functions were endorsed more than interpersonal functions, and were rated as significantly more effective. Overall, perceived effectiveness of NSSI for intrapersonal functions was significantly and positively predictive of NSSI severity, while interpersonal functions were significantly and negatively related. Perceived effectiveness of NSSI for intrapersonal functions, but not interpersonal functions, were significantly predictive of more frequent and intense suicide ideation and greater likelihood of suicide plans and attempts. Results highlight the importance of assessing the perceived effectiveness of NSSI for specific functions in identifying individuals at risk for more severe NSSI and suicide.

An Examination of Correlates for Adolescent Engagement in Nonsuicidal Self-Injury, Suicidal Self-Injury, and Substance Use

Little research has examined potential risk factors for direct versus indirect self-injury among adolescents. To address this limitation, 541 clinically referred adolescents were assessed using the interRAI Child and Youth Mental Health Assessment. Logistic regression analyses revealed that older females who experienced heightened depressive symptoms and neighborhood violence were at increased risk for direct self-injury, specifically nonsuicidal and suicidal self-injury. Additionally, adolescents who experienced higher levels of caregiver distress were at greater risk of suicidal self-injury. In contrast, older adolescents who experienced heightened aggressive behavior were at increased risk for one form of indirect self-injury, substance use. Findings suggest that nonsuicidal self-injury, suicidal self-injury, and substance use are associated with differential risk factors. Implications for targeted prevention strategies are discussed.

Use of Ecological Momentary Assessment (EMA) in Non-Suicidal Self-Injury (NSSI): A systematic review

Conceptualization and assessment of non-suicidal self-injury (NSSI) has evolved substantially in recent years. In both cross-sectional and longitudinal studies, NSSI and its related variables have traditionally been assessed retrospectively, leading to less precise studies of the mechanisms involved in the maintenance, cessation, or aggravation of this behavior. Ecological momentary assessment (EMA) enables real-time collection of patient states, which can be very useful in the study of the mechanisms implied in this behavior. This systematic review aims to elucidate the current status of EMA use in NSSI investigation. An exhaustive search in PubMed and PsycINFO was conducted up to September 2017. All papers included were focused on the study of NSSI using EMA. Studies with methodological diversity were included, which were afterwards organized according to main topic of studies. There were no ineligibility criteria based on age or diagnosis. Twenty-three papers were studied, the majority of which are short-term studies focused on the study of affect dynamics and the emotion-regulation function of NSSI. Implications of these results and recommendations for future research are discussed.

An Ecological Investigation of the Emotional Context Surrounding Nonsuicidal Self-Injurious Thoughts and Behaviors in Adolescents and Young Adults

Ecological momentary assessment (EMA) methodology was used to examine the emotional context of nonsuicidal self-injury (NSSI). Forty-seven adolescents and young adults used a novel smartphone app to monitor their emotional experiences, NSSI thoughts, and NSSI behaviors for 2 weeks. Momentary changes in both negative and positive emotions predicted greater intensity of NSSI thoughts at the subsequent assessment, while only increases in negative emotion predicted NSSI behaviors. Immediately following NSSI behaviors participants reported reduced high-arousal negative emotions and increased low-arousal positive emotions, suggesting that NSSI may be an efficient and effective method of regulating emotion. Findings highlight the importance of addressing emotion regulation in NSSI interventions.

Self-injurious behaviour in patients with anorexia nervosa: a quantitative study

BACKGROUND

Many patients with an eating disorder report difficulties in regulating their emotions and show a high prevalence of self-injurious behaviour. Several studies have stated that both eating disorder and self-injurious behaviour help emotion regulation, and are thus used as coping mechanisms for these patients. We aimed to determine the prevalence of self-injurious behaviour, its characteristics and its emotion-regulation function in patients with anorexia nervosa or an eating disorder not otherwise specified (n = 136).

METHODS

A cross-sectional design using a self-report questionnaire. Mann-Whitney U-tests were conducted to compare the background and clinical variables between patients with self-injurious behaviour and patients without this type of behaviour. Changes in emotional state before and after self-injurious behaviour were tested by Wilcoxon signed rank tests.

RESULTS

Our results showed a 41% prevalence of self-injurious behaviour in the previous month. Patients who performed self-injurious behaviour had a statistically significant longer treatment history for their eating disorder than those who did not. Whereas 55% of self-injuring patients had a secondary psychiatric diagnosis, only 21% of participants without self-injurious behaviour did. Regarding the impact of self-injurious behaviour, our results showed a significant increase in "feeling relieved" and a significant decrease in "feeling angry at myself", "feeling anxious" and "feeling angry at others". This indicates that self-injurious behaviour can be regarded as an emotion-regulation behaviour. Participants were usually aware of the causes of their self-injurious behaviour acts.

CONCLUSIONS

Professionals should systematically assess the occurrence of self-injurious behaviour in eating disorder patients, pay special attention to patients with more severe and comorbid psychopathology, and those with a long treatment history. This assessment should be followed by a functional analysis of the self-injurious behaviour and by effective therapeutic interventions alongside the eating disorder treatment.

Thoughts, images, and appraisals associated with acting and not acting on the urge to self-injure

OBJECTIVES

The aim of this study was to examine the frequency, content, and appraisals of thoughts and images occurring during urges to engage in non-suicidal self-injury (NSSI).

METHOD

Undergraduates (N = 154) with a history of NSSI completed an online survey of their thoughts, images, and appraisals when they acted on urges to engage in NSSI as well as when they resisted urges to self-injure.

RESULTS

Most (>90%) participants reported experiencing both thoughts and images during urges to engage in NSSI. During urges that resulted in self-injury, self-critical and hopeless thoughts were most distressing, and thoughts about relief from emotional distress were most comforting. Images of the anticipated injury were most common. During urges that did not result in self-injury themes of the futility of NSSI, positive self-talk, and the impact on others were most common. Images were most frequently of the negative impact on self and others, and the anticipated injury. Appraisals encouraging NSSI occurred when individuals did and did not act on their urges, but concurrent strong discouraging appraisals appeared to be protective on occasions when urges did not result in self-injury.

LIMITATIONS

Retrospective self-report was used to assess cognitive content. Generalisability of findings to non-student samples needs to be assessed.

CONCLUSIONS

Findings from this study may inform comprehensive assessment of thoughts and images associated with urges to engage in NSSI. NSSI interventions may need to promote thoughts, imagery and appraisals that discourage NSSI whilst simultaneously modifying cognitions that encourage NSSI.

Profiles of Emotion Deficits and Adolescent Nonsuicidal Self-Injury in an Inpatient Sample

This study examined profiles of specific emotion deficits, including poor emotion awareness, reluctance to express emotion, sadness inhibition and dysregulation, and anger inhibition and dysregulation. Self-report questionnaires assessed adolescents' emotion skills and nonsuicidal self-injury (NSSI) engagement, frequency, severity, methods, and age of onset. Latent profile analysis yielded a three-profile solution: Low Deficit (LD; n = 49), Unaware/Anger Dysregulated (UAD; n = 24), and Anger Inhibited (AI; n = 20) profiles. Adolescents in the UAD profile were more likely to engage in NSSI, displayed a higher NSSI frequency, and reported a higher number of NSSI methods when compared to adolescents in the LD profile. No links emerged for NSSI severity or age of onset.

Non-suicidal Self-Injury in Adolescence

PURPOSE OF REVIEW

Non-suicidal self-injury (NSSI) is a common mental health threat among adolescents. This review aims to present the current literature on epidemiology, etiology, and therapeutic approaches with a focus on the period of adolescence.

RECENT FINDINGS

NSSI is widespread among adolescents both in community as well as in clinical settings with lifetime prevalence rates between 17 and 60% in recent studies. It is influenced by multiple factors including social contagion, interpersonal stressors, neurobiological background, as well as emotional dysregulation and adverse experiences in childhood. There is still a lack of studies regarding the psychotherapeutic as well as the psychopharmacological treatment of NSSI in adolescence. Furthermore, sufficient evidence for prevention programs is missing.

Direct and indirect forms of childhood maltreatment and nonsuicidal self-injury among clinically-referred children and youth

BACKGROUND

Although exposure to direct forms of childhood maltreatment is among the most widely studied risk factors for nonsuicidal self-injury (NSSI), research on NSSI has largely overlooked the role of exposure to indirect forms of child maltreatment (i.e., witnessing domestic violence). To address this gap in the literature, the present study examined associations among both direct and indirect forms of child maltreatment and NSSI among clinically-referred children and youth.

METHODS

Data was collected using the interRAI Child and Youth Mental Health Assessment (ChYMH) at ten mental health agencies. The ChYMH is a comprehensive standardized clinical assessment tool completed by trained assessors using multiple sources. The study included a convenience sample of 747 children and youth (68% male) between ages 8-18 with complex mental health histories referred for inpatient or outpatient care in Ontario, Canada.

RESULTS

Univariate chi-square analyses indicated positive associations with NSSI and both direct (i.e., physical, sexual) and indirect child maltreatment (i.e., witnessing domestic violence). In a binary multivariate logistic regression analysis controlling for participant age and sex, only exposure to indirect child maltreatment emerged as multivariate predictor of NSSI.

LIMITATIONS

The sample was limited to only 10 mental health agencies and only consenting parents/guardians referred to mental health services suggesting the study may not be generalizable to all clinical samples.

CONCLUSION

The present study provides evidence that witnessing domestic violence in childhood is an important risk factor for NSSI. Clinical relevance includes implications for clinicians to develop targeted intervention and prevention strategies for NSSI for children who have witnessed domestic violence.

Opponent Process Theory Can Help Explain Some Effects of Resilience

We read the focal article by Britt, Shen, Sinclair, Grossman, and Klieger (2016) with special interest. About 10 years ago, we were asked to write a chapter on hardiness (Beehr & Bowling, 2005), and in doing so we had many observations about hardiness that were similar to Britt et al.’s observations about resilience. Our chapter was most closely aligned with the “capacity” concept of resilience, but we think that both the “capacity” approach and the “demonstration” approach to resilience have merit.
