Subtypes of non-suicidal self-injury based on childhood adversity

Understanding the subtypes of non-suicidal self-injury: A new conceptual framework based on a systematic review

Non-suicidal self-injury (NSSI) is a significant public health problem, but there is no consistent evidence of its risk factors. One possibility is that there are subtypes NSSI that have different risk factors and clinical symptoms. In this review we evaluated the evidence of subtypes to determine if there were consistent subtypes of NSSI that emerged across studies. Four databases (Medline; Embase; PsycINFO; Web of Science) were searched to identify studies that used data-driven approaches and were published before November 9, 2022. There were 21 studies with 23 unique samples for review. Most of the included studies used NSSI symptoms or personal characteristics as the subtyping indicators, revealing 2-5 subtypes of NSSI. Variations in subtyping indicators, sample characteristics, and statistical methods may have contributed to the inconsistent number and characteristics of subtypes across studies. A new conceptual framework is proposed to integrate these diverse findings, highlighting the important roles of NSSI function and psychological pain in differentiating NSSI subtypes. This framework sheds light on the differences among self-injurers and offers insights for future endeavors to address the complexities of NSSI.

Mood Disorders and Aggressive Traits Mediate Effects of Reported Childhood Adversity on Suicide Attempt Risk

BACKGROUND

Childhood adversity (CA) is linked to suicidal behavior as well as to mood disorders and aggressive traits. This raises the possibility that depression and aggressive traits mediate the relationship of childhood adversity to suicide risk. Moreover, it is not known if they operate independently or interactively.

AIMS

To determine whether, and how, mood disorders and aggressive traits mediate the effects of reported physical and sexual abuse on future suicidal behavior.

METHODS

Five hundred and forty-eight subjects, offspring of parents with mood disorders, were interviewed at baseline and at yearly follow-ups with questionnaires assessing aggression, mood disorders, and suicidal behavior. The mediation analysis involved a three-step process, testing the relationships between (1) CA and attempt; (2) CA and putative mediators; and (3) putative mediators and suicide attempt, adjusting for CA.

RESULTS

Aggressive trait severity and mood disorder onset each mediated the relationship between CA and future suicide attempts. Greater aggression severity also raised the hazard of the development of a mood disorder. If aggressive trait severity was clearly elevated, then onset of mood disorder did not increase further the hazard of the suicide attempt. Including family as a random effect had a much bigger effect on attempt outcome for physical abuse compared with sexual abuse.

CONCLUSIONS

Amelioration of aggressive traits and treatment of mood disorders in CA-exposed offspring of a parent with a mood disorder may prevent future suicide attempts and may reduce the risk of mood disorder. Familial factors influence the impact of childhood physical abuse but not sexual abuse. HIGHLIGHTSChildhood Adversity (CA) predicted future mood disorder and aggression severity.Depression and aggression mediate the relationship between CA and suicide attempts.When one mediator is present, the presence of the other does not increase the hazard.Between family variation contributed much more to suicidal behavior outcomes relative to the effect of physical abuse, but sexual abuse contributed to suicidal outcomes more than family variation.

A Hierarchical Cluster Analysis of Childhood Interpersonal Trauma and Dispositional Mindfulness: Heterogeneity of Sexual and Relational Outcomes in Adulthood

The current mixed-method study aimed to 1) identify different childhood interpersonal trauma (CIT) and dispositional mindfulness (DM) profiles in an adult sample; 2) illustrate these profiles with qualitative data documenting childhood sexual abuse (CSA) and CIT survivors' perceptions of their own DM; and 3) examine profile differences on sexual and relational outcomes. Participants were 292 adults who completed an online questionnaire. A subsample of participants having reported a history of CSA (n = 51) also completed semi-structured interviews. Hierarchical cluster, comparison, and content analyses were performed. Analyses yielded three profiles: 1) Lower victimization, high mindfulness; 2) Psychological victimization, low mindfulness; and 3) Multi-victimization, low mindfulness. Participants in profile 1 presented the lowest frequency of CIT experiences and the highest levels of DM and sexual and relational well-being. Profile 2 participants presented higher sexual and relational well-being (i.e., higher sexual satisfaction, lower sexual depression, and fewer interpersonal conflicts) than those in profile 3. By documenting distinct CIT and DM profiles and tying them to different levels of relational and sexual well-being, this study could guide practitioners in designing tailored interventions.

Differences in late adolescent psychopathology among youth with histories of co-occurring abuse and neglect experiences

BACKGROUND

Knowledge about the impacts of child abuse and neglect (CAN) experiences on late adolescent psychopathology has been limited by a failure to consider the frequent co-occurrence of CAN types and potential unique impacts of specific combinations.

OBJECTIVE

Using person-centered analyses, we aimed to identify unobserved groups of youth with similar patterns of lifetime CAN experiences before age 16 and differences in psychopathology symptom counts between groups two years later.

PARTICIPANTS AND SETTING

Participants were 919 adolescent-caregiver dyads (56% female; 56% Black, 7% Latina/o, 13% mixed/other).

METHODS

Prospective, multi-informant data, including child protective services records and caregiver and youth reports were collected, and youth completed a diagnostic interview at age 18.

RESULTS

Latent Class Analyses classified adolescents into four distinct groups based on patterns of physical neglect, supervisory neglect, and physical, sexual, and psychological abuse: "Low-Risk" (37%), "Neglect" (19%), "Abuse" (11%), and "Multi-type CAN" (33%). The Multi-type CAN class had significantly more major depressive, generalized anxiety, and nicotine use symptoms than the Low-Risk class, and more post-traumatic stress, antisocial personality, and illicit substance use symptoms, than Low-Risk and Neglect classes. The Abuse class had significantly more generalized anxiety and attention deficit/hyperactivity symptoms than the Low-Risk class, and more major depressive, antisocial personality, and illicit substance use symptoms, than Low-Risk and Neglect classes. The Neglect class did not have elevated psychopathology symptoms.

CONCLUSION

Findings highlight important differences in the associations between lifetime CAN experience patterns and psychopathology. Researchers should explore mechanisms underlying psychopathology that are impacted by different CAN experience patterns.

Happily Ever After? Life Satisfaction After Childhood Exposure to Violence

A plethora of research has linked exposure to violence during childhood to negative long-term physical health, mental health, and risk behavior outcomes. Yet, despite estimates that up to 60% of children in the United States will be exposed to violence, little is known about the impact on adult life satisfaction among different racial and ethnic groups, or for different types of violence exposure. This article seeks to explore factors that are associated with life satisfaction in adults who were exposed to family violence or physically abused as a child, while adjusting race, ethnicity, gender, and emotional support. Employing data from the 2010 Behavioral Risk Factor Surveillance System (BRFSS), links are examined between childhood exposure to violence and adult life satisfaction. For this study, noninstitutionalized adults aged 18 and above in the United States were included. Adults who reported exposure to physical abuse as a child had lower odds of reporting life satisfaction, and those with both physical abuse and interpersonal violence exposure had the lowest odds of long-term life satisfaction. Higher levels of income, emotional support, and marriage were associated with higher levels of satisfaction for both adults who were not exposed to violence as children and those who were. After controlling for sociodemographic factors, adults who identified as Asian or Pacific Islander had higher odds of reporting life satisfaction than their Caucasian counterparts. Implications from these findings include targeting interventions to increase emotional support and social networks for individuals who have been exposed to violence.

A typology of nonsuicidal self-injury in a clinical sample: A latent class analysis

Nonsuicidal self‐injury(NSSI) is a behavioural concern and can present in diverse ways, varying by method, frequency, severity, function and so forth. The possible combinations of these features of NSSI produce an array of profiles that makes evaluation and management of this behaviour challenging. The aim of this study was to build upon previous work that reduces the heterogeneity of NSSI patterns by using latent class analysis (LCA) to identify a typology of NSSI. Participants consisted of 235 outpatients aged 14–35 years attending a tertiary psychiatric hospital in Singapore who had reported at least one NSSI behaviour within the last year. Eight indicators captured using the Functional Assessment of Self‐Mutilation were used in the LCA: frequency of NSSI, length of contemplation before engaging in NSSI, usage of more than three NSSI methods, suicidal ideation and four psychological functions of NSSI, that is, social‐positive, social‐negative, automatic‐positive and automatic‐negative. The LCA revealed three distinct groups: Class 1—Experimental/Mild NSSI, Class 2—Multiple functions NSSI/Low Suicide Ideation and Class 3—Multiplefunctions NSSI/Possible Suicide Ideation. Multinomial logistic regression analyses were conducted to examine the associations between class membership and sociodemographic variables as well as measures of emotion dysregulation, childhood trauma, depression and quality of life. Females were overrepresented in Class 3. In general, Class 3 had the poorest scores followed by Class 2. Our analyses suggest that different NSSI subtypes require different treatment indications. Profiling patterns of NSSI may be a potentially useful step in guiding treatment plans and strategies.

Using the Body When There Are No Words for Feelings: Alexithymia and Somatization in Self-Harming Adolescents

The present case-control study aimed to investigate the relationship between alexithymia and somatic complaints in the psychopathological setting of non-suicidal self-injury (NSSI). A clinical sample of 134 adolescents (115 females; 85.5%) from 12 to 18 years old engaging in NSSI was compared with a control group of 243 high-school students (157 females; 64.6%) from 13 to 18 years old. Data were collected using two questionnaires: The Youth Self-Report 11-18 and the 20 Toronto Alexithymia Scale. In both cases and controls, the presence of somatization and alexithymia was associated with more severe psychopathological problems. Analyses were conducted to explore the association between somatic disorders and alexithymia. In the clinical group, somatic complaints were reported by 95.9% of alexithymic individuals, whereas only 44.3% of alexithymic adolescents reported somatic complaints. A one-way relationship emerged between somatization and alexithymia: while alexithymia would seem to be a factor associated with self-injury, somatic disorders were strongly associated with alexithymia, but not necessarily with self-injury. Among the self-harming adolescents, those with both alexithymia and somatization had a more severe psychopathological picture than the individuals with alexithymia but no somatization. This would suggest that, in the setting of NSSI, greater difficulty with identifying feelings is associated with somatization, and alexithymia would be an attribute common to self-harming behavior and somatization, both of which are characterized by the body being used to express psychological and emotional problems. Future research could further investigate alexithymia in self-harming individuals, in relation to any presence or absence of somatic disorders, with longitudinal assessments on any differences in their manifestation of self-injury and its psychopathological correlates.

Patterns of adverse childhood experiences and subsequent risk of interpersonal violence perpetration among men in Dar es Salaam, Tanzania

BACKGROUND

Adverse childhood experiences (ACEs), including abuse and neglect, are consistently found to be predictors of perpetration of intimate partner violence (IPV) and peer violence (PV) in adulthood. Children are often exposed to patterns of ongoing and/or multiple-type polyvictimization throughout the life course.

OBJECTIVES

To identify and characterize patterns of ACEs among men in Dar es Salaam, Tanzania and to examine the relationship between these patterns and perpetration of intimate partner violence (IPV) and peer violence (PV) in adulthood.

METHODS

We used latent class analysis to identify respondents with similar patterns of ACEs. The analysis was conducted with a sample of 987 men.

RESULTS

We uncovered five distinct classes of men with specific patterns of ACEs. One consisted of nonvictims and four included various forms of polyvictimization. Men in the polyvictimization classes that included non-violent family dysfunction had significantly higher odds of perpetrating psychological IPV compared to the other three classes (AORs 2.33 and 3.04 compared to nonvictims). Men in the polyvictimization classes that included any sexual violence and/or non-violent family dysfunction had significantly higher odds of perpetrating PV compared to the other two classes (AORs 3.54, 6.10, and 7.42 compared to nonvictims).

CONCLUSIONS

These findings suggest that distinct patterns of exposure to ACEs among this population are differentially related to perpetration of IPV and PV in adulthood. These findings highlight the importance of child development interventions in low-and middle-income countries, both for the primary prevention of child adversity and for mitigation of the cognitive and emotional effects of ACEs.

Functions of Non-Suicidal Self-Injury in Late Adolescence: A Latent Class Analysis

This study employed latent class analysis utilizing an array of features of non-suicidal self-injury (NSSI) in order to identify distinct subgroups of self-injurers. Participants were 359 undergraduates with NSSI history. Indicator variables were lifetime and last year frequency rates, number of methods, scarring, pain during self-injury, and functions of NSSI. Analyses yielded mild/experimental NSSI, moderate NSSI, moderate multiple functions NSSI, and severe NSSI groups, endorsing low, moderate, moderate multiple functions, and high frequencies of self-injury and presence of functions, respectively. Following class assignment, groups differed on self-esteem, social support and belongingness, internalizing symptoms, suicidal ideation and behaviors, and additional NSSI constructs. These subtype analyses emphasize matching phenotypes of NSSI to specific interventions considering dimensions of clinical functioning.

Childhood maltreatment profiles among incarcerated Chinese males and their associations with personality disorder symptoms and criminal behaviors

Few studies have investigated how multiple childhood maltreatment experiences co-occur and influence personality disorder symptoms and criminal behaviors in Chinese population. Using a large sample of 1001 incarcerated Chinese males (M_age = 30.86 years), the current study identified profiles of self-reported childhood maltreatment experiences and examined their associations with Axis II personality disorder symptoms and criminal behaviors. Latent profile model was built on five types of maltreatment (emotional, physical, and sexual abuse; emotional and physical neglect). Results showed high prevalence and co-occurrence of maltreatment, and revealed four profiles: Minimal Maltreatment (61.5%), Low Abuse and High Neglect (26.6%), High Sexual Abuse with Multiple Maltreatment (4%), and High Physical and Emotional Maltreatment (7.8%). Profiles with high neglect level showed higher Cluster A personality disorder symptoms as well as borderline, avoidant, and dependent symptoms than those with minimal maltreatment. The two profiles with moderate to high abuse level showed elevated symptoms in all clusters of personality disorder and higher prevalence of juvenile offense than the other two profiles. High Physical and Emotional Maltreatment profile also had higher prevalence of violent offending and recidivism. These findings revealed the importance and utility of identifying profiles of co-occurring maltreatment to tailor treatment based on specific maltreatment experiences and their co-occurrence to address negative outcomes associated with each maltreatment profile.

Profiles and behavioral consequences of child abuse among adolescent girls and boys from Barbados and Grenada

The current study used latent class analysis to uncover groups of youths with specific abuse (physical, emotional, and sexual) profiles in and outside the family, and identify how membership in each abuse group is associated with behavioral outcomes. Data were collected among a sample of male (n = 662; M_age = 13.02 years) and female (n = 689; M_age = 12.95 years) children and adolescents (9-17 years old) from Barbados and Grenada. Self-report surveys were completed by participants in school settings. Three latent classes of child abuse were distinguished among boys, including 'low abuse' (39.2% of the sample), 'physical and emotional abuse high outside/medium in the family' (43.2%), and 'high overall abuse' (17.6%). Among girls, four unique classes were recovered: 'low abuse' (40.7%), 'high physical and emotional abuse outside the family' (7.6%), 'high emotional and moderate physical abuse' (33.9%), and 'high overall abuse' (17.8%). Compared with members of low abuse groups, youths who reported having experienced high/moderate levels of various forms of violence, including those who were abused in multiple ways and across the two settings ('high overall abuse'), were significantly more likely to engage in violent and hostile behavior. Abused and non-abused youths did not differ on non-violent conflict resolution skills. The significance of present findings for future research and practice is discussed.

Ethical practices in community-based research in non-suicidal self-injury: A systematic review

BACKGROUND

The growing interest in community-based research on non-suicidal self-injury (NSSI) reflects the high prevalence rates found among vulnerable adolescents and young adults. A significant concern in research with vulnerable populations, and on sensitive topics, is the development of an ethical framework that protects the needs and rights of the participants while responding to researchers' goals and limitations and the broader clinical and public health concerns.

AIM

The aim of the present study was to review the ethical practices followed in community-based research on NSSI.

METHOD

A systematic review of literature was conducted, based on PRISMA guidelines, on community-based surveys in NSSI, published between 1995 and 2016. A total of 93 studies were included in the review.

RESULTS

The results examine a range of ethical issues; the procedures for consent and assent for study participation, protection of confidentiality and the limits of confidentiality, assessment of imminent risk of suicide and subsequent processes, and debriefing measures. The interaction between the study characteristics and the reported ethical procedures has been examined, with a focus on participant age, study design (cross-sectional or longitudinal), survey modality (paper-based survey or online survey) and primary variable/s of interest (only NSSI or NSSI and suicidal ideation/behavior) under study. The review describes the typical ethical practices in community-based research on NSSI, identifies the gaps in the existing literature, and has implications for the formulation of best-practice guidelines.

What do we know about child abuse and neglect patterns of co-occurrence? A systematic review of profiling studies and recommendations for future research

Latent class (LCA) and latent profile (LPA) analysis represent methodological approaches to identify subgroups of maltreated individuals. Although research examining child abuse and neglect (CAN) profiles is still rare, the application of person-centered techniques to clarify CAN types co-occurrence has substantially increased in recent years. Therefore, the aim of the present study was to provide a summary and critical evaluation of the findings of LCA/LPA child maltreatment research to: (a) systemize the current understanding of patterns of maltreatment across populations and (b) elucidate interactive effects of CAN types on psychosocial functioning. A search in PsychInfo, Eric, PubMed, Scopus, and Science Direct, and Google Scholar was performed. Sixteen studies examining the co-occurrence between child physical abuse, emotional abuse, sexual abuse, neglect, and/or exposure to domestic violence were identified. A critical review of the studies revealed inconsistent findings as to the number of CAN classes, but most research uncovered a poly-victimized and a low abuse group. Further, multiple victimization was associated with most adverse internalizing and externalizing outcomes, especially when sexual abuse was present. Exposure to physical and emotional abuse was frequently reported to lead to behavioural problems. Based on the present study results, we provide a set of recommendations for surpassing the current methodological and conceptual limitations in future research.

Adverse Childhood Experiences Among Immigrants to the United States

A growing number of studies have examined the "immigrant paradox" with respect to health behaviors in the United States. However, little research attention has been afforded to the study of adverse childhood experiences (ACE; neglect, physical and sexual abuse, and witnessing violence) among immigrants in the United States. The present study, using Waves I and II data from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), aims to address these gaps by comparing forms of ACE of first- and second-generation immigrants with native-born American adults in the United States. We also examined the latent structure of ACE among immigrants and conducted analyses to assess the psychiatric correlates of identified latent classes. With the exception of neglect, the prevalence of ACE was markedly higher among native-born Americans and second-generation immigrants compared with first-generation immigrants. Four latent classes were identified-limited adverse experience ( n = 3,497), emotional and physical abuse ( n = 1,262), family violence ( n = 358), and global adversity ( n = 246). The latter three classes evinced greater likelihood of being diagnosed with a mood, anxiety, personality, and substance use disorder, and to report violent and non-violent antisocial behavior. Consistent with prior research examining the associations between the immigrant paradox and health outcomes, results suggest that first-generation immigrants to the United States are less likely to have experienced physical and sexual abuse and witness domestic violence. However, likely due to cultural circumstances, first-generation immigrants were more likely to report experiences that are deemed neglectful by Western standards.

The Relationship between Childhood Maltreatment and Non-Suicidal Self-Injury: A Systematic Review

INTRODUCTION

Childhood maltreatment (CM) has been associated with an increased risk of non-suicidal self-injury (NSSI) and suicidal behaviors. However, the exact nature of the association between CM and NSSI is currently unclear. The present review aimed to systematically investigate the association between CM and NSSI in adolescence and early adulthood.

METHODS

A systematic search of four major electronic databases covering both medical and social science research (PubMed, Scopus, Science Direct, and PsycINFO) was conducted.

RESULTS

Overall, 20 cross-sectional studies including a total of 22,517 individuals, 3 longitudinal follow-up studies including 1,728 individuals, and 3 retrospective studies including 62,089 individuals were selected. It appears that CM is a significant risk factor for both NSSI and suicide attempts. The increased vulnerability to NSSI seems to be related to experiences of CM, particularly sexual abuse. Gender differences were also found. Generally, when compared to males, females who experienced CM seem to be more vulnerable to presenting with NSSI and suicidal behaviors.

CONCLUSION

There is a positive association between CM and NSSI. The importance of early detection and risk reduction of self-injurious behavior for adolescents is discussed.

Hypothalamic-pituitary-adrenal axis, childhood adversity and adolescent nonsuicidal self-injury

BACKGROUND

Whereas childhood adversity (CA) and the hypothalamus-pituitary-adrenal (HPA) axis have been suggested to play a major role in the etiology of non-suicidal self-injury (NSSI), no study has thus far investigated both its associations and interactions with adolescent NSSI.

METHOD

We investigated CA (antipathy, neglect, physical, psychological, and sexual abuse) and indices of HPA axis activity (salivary and hair cortisol) in a clinical sample of 26 adolescents engaging in NSSI and 26 age- and gender-matched healthy controls (HC). We used standardized interviews for the assessment of CA (CECA), NSSI (SITBI-G), and axis I diagnoses (MINI-KID). Salivary cortisol sampling was surveyed using a monitoring system and instructed via telephone calls.

RESULTS

Adolescents engaging in NSSI exhibited significantly higher cortisol awakening responses compared to HC. No differences were found with respect to the diurnal slope or hair cortisol. In the presence of CA, healthy adolescents showed flatted diurnal cortisol slopes while those engaging in NSSI exhibited significantly steeper ones.

CONCLUSIONS

Our findings indicate that adolescents engaging in NSSI may exhibit a stronger cortisol awakening response, potentially in expectation of strain. However, elevated cortisol levels may not be maintained throughout the day, especially among adolescents with a history of CA.

Predictors for DSM-5 nonsuicidal self-injury in female adolescent inpatients: The role of childhood maltreatment, alexithymia, and dissociation

The purpose of this study was to examine the relationship between various adverse childhood experiences, alexithymia, and dissociation in predicting nonsuicidal self-injury (NSSI) in an inpatient sample of female adolescents. Seventy-two adolescents (aged 14-18 years) with NSSI disorder (n=46) or mental disorders without NSSI (n=26) completed diagnostic interviews and self-report measures to assess NSSI disorder according to the DSM-5 criteria, childhood maltreatment, alexithymia, and dissociation. Alexithymia and dissociation were highly prevalent in both study groups. Multivariate logistic regression analyses indicated that only alexithymia was a significant predictor for NSSI, whereas childhood maltreatment and dissociation had no predictive influence. The association between alexithymia and NSSI emphasizes the significance of emotion regulation training for female adolescents with NSSI. Efforts to reduce NSSI behavior should therefore foster skills to heighten the perception and recognition of one's own emotions.

Nonsuicidal Self-Injury

Nonsuicidal self-injury (NSSI) is a serious and prevalent problem within the adolescent population. NSSI is associated with a variety of psychiatric diagnoses and behavioral concerns. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition, has recognized NSSI as its own separate diagnosis. Although there are unique differences between NSSI and suicidal behaviors, a link exists between these behaviors. It is crucial that pediatric nurse practitioners who provide care for adolescents possess a thorough understanding of NSSI. In this continuing education article, NSSI will be discussed in terms of epidemiology, diagnosis and co-morbidity, risk factors, relationship with suicidal behaviors, and implications for practice.

Mental health consequences of violence against women and girls

PURPOSE OF REVIEW

Recent studies on mental health consequences of violence against women and girls were reviewed in a range of situations.

RECENT FINDINGS

Although several studies continued to show cross-sectional associations between child sexual abuse (CSA) and mental health outcomes, a few prospective studies showed a robust association between CSA and depression. Studies on the impact of dating violence are still at a nascent stage and focus on antecedents of violence rather than its consequences. Women at higher risk, such as adolescents, migrants, the homeless, and women in the perinatal period have been studied and specific vulnerabilities identified. Women reporting bidirectional violence had higher rates of depression and post-traumatic stress disorder (PTSD). Cumulative violence, severity of violence, and recent violence are associated with higher morbidity. Studies among women in conflict zones have emphasized the role of different forms of sexual and physical violence on mental health.

SUMMARY

Newer emerging areas that need more research include mental health consequences of women in conflict zones and among same sex relationships. There are also few studies on the violence experience of both older women and adolescents. The need to better delineate the psychopathology of complex manifestations of PTSD is underscored.
