Parenting in the early years and self-harm in adolescence: The role of control and reward systems in childhood

BACKGROUND

Research suggests that early parenting may contribute to the development of self-harm but this has not been examined longitudinally. In this study, we explored the relationship between early parenting and self-harm in adolescence and considered whether (1) emotion regulation and (2) decision-making in childhood mediate the relationship between early parenting and self-harm.

METHOD

Using longitudinal data from the Millennium Cohort Study (MCS), we tested mediation models exploring the relationship between early parenting and self-harm in adolescence via emotion regulation and decision-making. Parenting was assessed at age 3 with measures of conflict, closeness and discipline. The trajectories of independence & self-regulation and emotional dysregulation were modelled from ages 3 to 7 years through latent growth curve analysis, with individual predicted slope and intercept values used in the mediation models. Decision-making (deliberation time, total time, delay aversion, quality of decision making, risk adjustment, risk-taking) was assessed using the Cambridge Gambling Task (CGT) at age 11.

RESULTS

In our sample (n = 11,145), we found no evidence of a direct association between early parenting and self-harm in adolescence. However, there were indirect effects of parenting (conflict and closeness) on self-harm via the slope of emotional dysregulation. Furthermore, delay aversion was positively associated with self-harm in adolescence.

LIMITATIONS

It must be acknowledged that we cannot determine causality and that self-report measures of parenting are vulnerable to several biases.

CONCLUSION

The findings support early identification and interventions for children exhibiting chronic emotional dysregulation and decision-making characterised by a bias for smaller, immediate over larger, delayed rewards.

Hiding in the open: Consideration of nonsuicidal self-injury by proxy as a clinically meaningful construct

Nonsuicidal self-injury (NSSI) is defined as the deliberate destruction of one's own body tissue without suicidal intent and for purposes not socially sanctioned. However, this definition limits the understanding and assessment of NSSI by excluding a clinically relevant form of NSSI that is both self-driven and associated with self-injurious intentions: NSSI by proxy. Specifically, we propose that NSSI by proxy be defined as the intentional destruction of one's own body tissue through the elicitation of another being's (e.g., human, animal) actions, wherein the agency of the person being injured is a critical facet of the behavior. We review the literature supporting the clinical relevance of this behavior, as well as its similarities to traditional NSSI. Next, we propose four behaviors that may be conceptualized as NSSI by proxy, and identify two other behaviors that warrant further investigation. Finally, we identify future directions for research in this area and implications for the assessment and treatment of NSSI.

Comparing self-harming intentions underlying eating disordered behaviors and NSSI: Evidence that distinctions are less clear than assumed

OBJECTIVE

Eating disordered (ED) behaviors (i.e., binge eating, compensatory behaviors, restrictive eating) and nonsuicidal self-injury (NSSI; intentional and nonsuicidal self-harm) are highly comorbid and share several similarities, including consequent pain and physical damage. However, whereas NSSI is considered direct self-harm, ED behaviors are considered indirect self-harm. These distinctions stem from theoretical understanding that NSSI is enacted to cause physical harm in the moment, whereas ED behaviors are enacted for other reasons, with consequent physical harm occurring downstream of the behaviors. We sought to build on these theoretically informed classifications by assessing a range of self-harming intentions across NSSI and ED behaviors.

METHOD

Study recruitment was conducted via online forums. After screening for inclusion criteria, 151 adults reported on their intent to and knowledge of causing physical harm in the short- and long-term and suicide and death related cognitions and intentions when engaging in NSSI and specific ED behaviors.

RESULTS

Participants reported engaging in ED and NSSI behaviors with intent to hurt themselves physically in the moment and long-term, alongside thoughts of suicide, and with some hope and knowledge of dying sooner due to these behaviors. Distinctions across behaviors also emerged. Participants reported greater intent to cause physical harm in the moment via NSSI and in the long-run via restrictive eating. NSSI and restrictive eating were associated with stronger endorsement of most suicide and death-related intentions than binge eating or compensatory behaviors.

CONCLUSIONS

Findings shed light on classification of self-harming behaviors, casting doubt that firm boundaries differentiate direct and indirectly self-harming behaviors.

Similarities and Differences in the Functions of Nonsuicidal Self-Injury (NSSI) and Sex as Self-Injury (SASI)

Differences and similarities were studied in the functions of two different self-injurious behaviors (SIB): nonsuicidal self-injury (NSSI) and sex as self-injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and SASI (n = 76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only. Adolescents reporting both NSSI and SASI endorsed the highest number of functions for both behaviors. Clinical implications are discussed, emphasizing the need for emotion regulation skills.

Adolescents' Daily Worries and Risky Behaviors: The Buffering Role of Support Seeking

With worries and risky behaviors becoming more prominent in adolescence, this study investigated bidirectional temporal connections between these two important adolescent concerns, that is, whether change in one concern is linked to change in the other either within the same day or during the next day. We also tested whether the coping strategy of seeking support from family and friends moderated the link between worries and risky behaviors. For 10 days, an ethnically and racially diverse sample of adolescents (N = 103; M age = 18.0) reported on 26 common worries, 18 risky behaviors, and the impact of seeking support from others. Multilevel models showed that worries and risky behaviors covaried on the same day and that worries predicted next-day risky behavior for male but not female participants. In contrast, risky behaviors did not predict next-day worries. For adolescents reporting negative experiences of support seeking, worries led to next-day risky behaviors and risky behaviors led to next-day worries. Female adolescents' positive support-seeking experiences buffered the association between risky behaviors and next-day worries. These results were significant beyond any influence of daily negative mood or depressive and anxiety symptoms. The data demonstrate that worries and risky behaviors may be situational triggers for each other and highlight the importance, from intervention perspectives, of adolescents' communication of concerns to others.
