HISTORICAL CONTEXT
Self-Inflicted Injury
Most studies of SII have been conducted by suicide
researchers, and important distinctions between suicidal and
nonsuicidal self-injury have only been acknowledged recently
(Linehan, 1997; Muehlenkamp & Gurierrez, 2004).
Offer and Barglow (1960) identified a relatively large subgroup
of hospitalized youth who harmed themselves without suicidal
intent.
Current research on adolescent suicide and nonsuicidal SII is
focused on:
•
•
•
•
Understanding the etiology of SII
Placing adolescent SII within a theoretical context
Determining how to represent SII within the DSM
Developing a standard of care for adolescents who engage in SII
HISTORICAL CONTEXT
Borderline Personality Disorder
Historically, the term borderline resulted from difficulties
diagnosing those who did not fit into the psychiatric
nomenclature of the early to mid 20th century.
Kernberg (1967) was among the first to identify borderline
personality organization as a specific and stable
personality pattern.
DSM-III (APA, 1980) established diagnostic criteria for
BPD.
Current research focuses on the dysfunctional
psychosocial and biological underpinnings of BPD.
HISTORICAL CONTEXT
Borderline Pathology in Childhood
Although research on childhood borderline pathology
(BP) evolved in parallel with the adult literature, existing
research with youth remains extremely limited in scope.
Researchers studying the development of BPD generally
describe a developmental pathway characterized by:
• Sequential comorbidity
• Heterotypic continuity
DIAGNOSTIC, TERMINOLOGICAL,
AND CONCEPTUAL ISSUES
DSM-IV-TR (2000)
Self-inflicted injury is included in the criterion lists of major
depression and BPD.
Because BPD is a controversial diagnosis for adolescents
many clinicians assign one or more Axis I disorders to selfinjuring youth, especially major depression.
Ongoing efforts to list SII within the DSM as a stand-alone
diagnosis.
Debate around BPD diagnosis, especially for
adolescents.
There is increasing evidence that precursors to BPD
appear well before age 18 (Bradley, Zittel Conklin, & Westen, 2005).
ETIOLOGICAL FORMULATIONS
Biosocial developmental model of borderline
personality development (Crowell, et al., 2009)
Trait impulsivity and emotional sensitivity are early-emerging
biological vulnerabilities that confer risk for SII, BPD, and other
disorders characterized by poor behavioral control.
Extreme emotional lability is shaped and maintained within
high-risk developmental contexts, which are characterized by
intermittent reinforcement of aversive behaviors paired with
chronic invalidation of intense expressions of emotion.
Over time, biological vulnerabilities interact with environmental
risks to potentiate more extreme behavioral and emotion
dysregulation.
ETIOLOGICAL FORMULATIONS
By adolescence, these Biology × Environment
interactions promote a constellation of identifiable
problems and maladaptive coping strategies such as SII,
which indicates heightened risk for BPD.
Early features of borderline pathology may further
exacerbate risk for BPD by negatively affecting one’s
abilities to navigate stage-salient developmental tasks,
form appropriate interpersonal relationships, and develop
healthy strategies for coping with distress.
FAMILIALITY AND HERITABILITY
There are strong biological underpinnings for both BPD
and SII.
SII also aggregates in families and includes a clinical
phenotype characterized by both suicide and suicide
attempts (Brent & Mann, 2005).
Family studies of those with BPD reveal significant
familial aggregation of mood and impulse control
disorders (White et al., 2003).
BPD co-aggregates with mood and anxiety disorders,
alcohol and drug abuse/dependence, pain disorder,
and several personality disorders.
GENETICS AND
NEUROTRANSMITTER DYSFUNCTION
Dopamine
There is consensus that DA dysfunction contributes to some of the
behavioral traits seen in BPD, including SII (Osuch & Payne, 2009; Sher &
Stanley, 2009).
Serotonin
Deficits in central 5HT have been associated consistently with mood
disorders, suicidal behaviors, and aggression (Kamali, Oquendo, & Mann,
2002).
Other Biological Vulnerabilities
Chronic stress leads to elevated LHPA axis responses that are
involved in suicidal behavior.
Oxytocin dysregulation may contribute to the difficulty those with BPD
experience in relationships (Stanley & Siever, 2010).
Deficits within the prefrontal cortex may contribute to suicidal and
other impulsive behaviors through a diminished capacity to inhibit
strong impulses.
CONTEXTUAL AND FAMILY RISK
FACTORS
Family processes that shape emotion dysregulation
have been well delineated in such samples and may
translate well to youth at risk for BPD (Beauchaine et al., 2009).
Invalidating caregiving environment.
Emotional lability is shaped within families via operant
conditioning.
Mixed results on child abuse research highlights the
importance of the interplay between biological and
psychosocial risks.
THEORETICAL SYNTHESIS AND
FUTURE DIRECTIONS
BPD and SII likely emerge due to repeated, complex
interactions between biological vulnerabilities and
contextual stressors.
By adolescence, there are a constellation of identifiable
problems and maladaptive coping strategies, such as SII,
that indicate heightened risk for BPD.
BP features may further exacerbate risk for BPD by
affecting a person’s ability to navigate stage salient
developmental tasks, form appropriate interpersonal
relationships, and develop healthy strategies for coping with
distress.
