Problem solving moderates the effects of life event stress and chronic stress on suicidal behaviors in adolescence

The present study examined the unique and interactive effects of stress and problem-solving skills on suicidal behaviors among 102 inpatient adolescents. As expected, life event stress and chronic stress each significantly predicted suicidal ideation and suicide attempt. Problem solving significantly predicted suicidal ideation, but not suicide attempt. Problem solving moderated the associations between life event stress and suicidal behaviors, as well as between chronic stress and suicidal ideation, but not chronic stress and suicide attempt. At high levels of stress, adolescents with poor problem-solving skills experienced elevated suicidal ideation and were at greater risk of making a nonfatal suicide attempt. The interactive effects decreased to non-significance after controlling for depressive symptoms and hopelessness. Clinical implications are discussed.

Borderline personality disorder in adolescents: evidence in support of the Childhood Interview for DSM-IV Borderline Personality Disorder in a sample of adolescent inpatients

Empirical evidence is increasing in support of the validity of the construct of borderline personality disorder (BPD) in adolescence. There is growing consensus that the early identification and treatment of emerging borderline traits may be an important focus. However, few diagnostic (questionnaire- or interview-based) measures specifically developed or adapted for adolescents and children exist. The Childhood Interview for DSM-IV Borderline Personality Disorder (CI-BPD) [Zanarini, 2003] is a promising interview-based measure of adolescent BPD. Currently, no studies have explicitly been designed to examine the psychometric properties of the CI-BPD. The aim of the current study was to examine various psychometric properties of the CI-BPD in an inpatient sample of adolescents (n = 245). A confirmatory factor analytic approach was used to examine the internal factor structure of the 9 CI-BPD items. In addition, internal consistency, interrater reliability, convergent validity (with clinician diagnosis and 2 questionnaire-based measures of BPD), and concurrent validity (with Axis I psychopathology and deliberate self-harm) were examined. Similar to several adult studies, the confirmatory factor analytic results supported a unidimensional factor structure for the CI-BPD, indicating that the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria on which the CI-BPD is based constitute a coherent combination of traits and symptoms even in adolescents. In addition, other validity criteria were excellent. Taken together, the current study provides strong evidence for the validity of the CI-BPD for use in adolescents.

The Relation between Anxiety Disorder and Experiential Avoidance in Inpatient Adolescents.

The current study aimed to examine the relation between experiential avoidance and anxiety disorders, as well as the usefulness of the Avoidance and Fusion Questionnaire for Youth (AFQ-Y; Greco, Lambert, & Baer, 2008) in detecting anxiety disorder in a sample of adolescent inpatients. First, the relation between experiential avoidance and anxiety among inpatient adolescents was investigated from categorical and dimensional points of view, making use of self-report and parent report, as well as clinical interview, while controlling for depression and externalizing problems. Second, we sought to establish the clinical utility value of the AFQ-Y by determining the sensitivity, specificity, and clinical cutoff score of this measure in predicting anxiety disorder. To this end, a sample of inpatient adolescents (N = 111) with a mean age of 16.14 (SD = 1.39) years completed the AFQ-Y, alongside interview- and questionnaire-based measures of psychopathology. Results showed a significant relation between anxiety disorder and experiential avoidance, independent of depression. Receiver operating characteristics analysis revealed that the AFQ-Y has moderate accuracy (area under the curve = .815, SE = .047, p < .001) in discriminating adolescents with a diagnosis of any anxiety disorder (cutoff score 26.5; sensitivity = .74, specificity = .76). Given the comorbidity of anxiety and depression in this sample, this cutoff is not indicative of pure anxiety disorder but may be helpful in predicting those with emotional disorders in general.

Assessing attachment in adolescence: A psychometric study of the Child Attachment Interview.

Research has established the quality of attachment as an important correlate and predictor of psychological well-being. Adolescence represents an important transitional period and is associated with considerable changes in psychosocial functioning and centrally in attachment relationships. However, measures of attachment are rarely examined for their psychometric properties in adolescence. In an attempt to address this limitation, the current study reports on the use of the Child Attachment Interview (CAI) in adolescents. Our broad aim was to explore the psychometric properties of the CAI classifications and subscales among adolescents with psychiatric disorder in the United States by (a) evaluating interrater reliability of the CAI, (b) examining the factor structure of the CAI subscales in adolescents, (c) examining relations between CAI classifications and subscales, (d) evaluating concurrent validity by assessing relations between the CAI and established questionnaire-based measures of attachment routinely used in adolescent samples, and (e) evaluating convergent validity by exploring relations between the CAI and parent- and self-reported psychopathology and peer relations. One hundred ninety-four inpatient adolescents were recruited. Analyses revealed adequate interrater agreement and revealed 3 factors that generally mirror those associated with the Adult Attachment Interview. Concurrent and convergent evidence to support the use of CAI attachment classifications and subscale scores in adolescents was provided.

THE INCREMENTAL VALIDITY OF BORDERLINE PERSONALITY DISORDER RELATIVE TO MAjOR DEPRESSIVE DISORDER FOR SUICIDAL IDEATION AND DELIBERATE SELF-HARM IN ADOLESCENTS

Few studies have examined the relation between suicide-related behaviors and Borderline Personality Disorder (BPD) in adolescent samples. The current study investigated the incremental validity of BPD relative to Major Depressive Disorder (MDD) for suicide-related behaviors in a psychiatric sample of adolescents at the cross-sectional level of analysis. The sample included N = 156 consecutive admissions (55.1% female; M age = 15.47; SD = 1.41), to the adolescent treatment program of an inpatient treatment facility. Of the sample 19.2% (n = 30) met criteria for BPD on the Child Interview for DSM-IV Borderline Personality Disorder and 39.1% (n = 61) met criteria for MDD on the Computerized Diagnostic Interview Schedule for Children-IV. Results showed that BPD conferred additional risk for suicidal ideation and deliberate self-harm. Our findings support the clinical impression that BPD should be evaluated in inpatient samples of adolescents either through intake interviews or more structured assessments.

The Role of Experiential Avoidance in the Association Between Borderline Features and Emotion Regulation in Adolescents

Difficulties in emotion regulation are one of the core features of borderline personality disorder (BPD). Individuals with BPD also report higher levels of experiential avoidance (EA) compared to controls. These constructs have never been studied concomitantly in adolescents. First, given the conceptual similarity of difficulties in emotion regulation and EA, the authors sought to determine whether EA provides incremental validity, above emotion dysregulation, in its association with borderline features. Second, EA was explored as a mediator in the relation between difficulties in emotion regulation and borderline features. The sample included 208 adolescents recruited from an inpatient psychiatric unit (M(age) = 15.96, SD = 1.39; females = 60.1%). Borderline personality features were assessed using the self-report Borderline Personality Features Scale for Children (Crick, Murray-Close, & Woods, 2005). EA was assessed using the Avoidance and Fusion Questionnaire for Youth (Greco, Lambert, & Baer, 2008), and difficulties in emotion regulation were assessed using the Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2004). Greater borderline personality features were associated with significantly higher levels of EA and difficulties in emotion regulation. Hierarchical regression analyses showed that EA made a small, but significant, incremental and independent contribution to borderline features when added to a model already including difficulties in emotion regulation. In addition, EA partially mediated the relation between difficulties in emotion regulation and borderline features. EA and emotion regulation are both important targets of treatments aimed at decreasing borderline personality features in adolescents.

The relation between experiential avoidance, alexithymia and emotion regulation in inpatient adolescents.

Recently, efforts have been made to better understand constructs that are associated with difficulties in emotion regulation in hopes of identifying underlying mechanisms that may be valuable targets for intervention. Against this background, the present study had two aims. Firstly, we wanted to explore the relation between emotion regulation, experiential avoidance and alexithymia by determining whether adolescents with elevated scores on a measure of alexithymia would report deficits in emotion regulation and experiential avoidance. Secondly, we sought to evaluate the role of experiential avoidance as a mediator in the relation between alexithymia and emotion regulation. The sample (N = 64) consisted of adolescents recruited from an inpatient facility of which approximately 30% were classified as having alexithymia. The results of this study indicate that adolescents with alexithymia report deficits in emotion regulation and elevated experiential avoidance. Experiential avoidance mediated the relation between alexithymia and emotion regulation, indicating that while the inability to effectively use language to identify and describe emotional states is strongly correlated with difficulties in regulating one’s emotions, this relation is mediated by the unwillingness to tolerate aversive private experiences. Limitations and strengths of the present study are also noted.

A preliminary study of the relation between trauma symptoms and emerging BPD in adolescent inpatients.

The relation between trauma and borderline personality disorder (BPD) has been studied in great detail with adults, but few studies have examined this link in adolescents. Furthermore, virtually nothing is known about how different aspects of trauma relate to BPD and whether trauma symptoms reflect actual trauma history in adolescents diagnosed with BPD. Using a sample of 147 adolescent psychiatric inpatients, the authors examined the concurrent link between trauma symptoms, trauma history, and BPD. Findings suggest that adolescents with BPD are more likely than their non-BPD counterparts to have a history of sexual trauma and to report sexual concerns. However, the link between BPD and sexual concerns is not completely explained by increased sexual trauma history in the BPD group, indicating that there is some relation between BPD and sexual concerns independent of trauma history. These findings are discussed within an attachment framework. The preliminary nature of this study is noted and used as the basis for encouraging future research in the area.

First empirical evaluation of the link between attachment, social cognition and borderline features in adolescents.

OBJECTIVE Several developmental models of borderline personality disorder (BPD) emphasize the role of disrupted interpersonal relationships or insecure attachment. As yet, attachment quality and the mechanisms by which insecure attachment relates to borderline features in adolescents have not been investigated. In this study, we used a multiple mediational approach to examine the cross-sectional interplay between attachment, social cognition (in particular hypermentalizing), emotion dysregulation, and borderline features in adolescence, controlling for internalizing and externalizing symptoms. METHODS The sample included 259 consecutive admissions to an adolescent inpatient unit (Mage=15.42, SD=1.43; 63.1% female). The Child Attachment Interview (CAI) was used to obtain a dimensional index of overall coherence of the attachment narrative. An experimental task was used to assess hypermentalizing, alongside self-report measures of emotion dyregulation and BPD. RESULTS Our findings suggested that, in a multiple mediation model, hypermentalizing and emotion dysregulation together mediated the relation between attachment coherence and borderline features, but that this effect was driven by hypermentalizing; that is, emotion dysregulation failed to mediate the link between attachment coherence and borderline features while hypermentalizing demonstrated mediational effects. CONCLUSIONS The study provides the first empirical evidence of well-established theoretical approaches to the development of BPD.

The Validity of the MSI-BPD Among Inpatient Adolescents

Although the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) has shown validity in adult samples, only one study has explored its validity in adolescents and, to our knowledge, the measure has not been validated with inpatient adolescents. The aim of the current study was to evaluate the reliability, and convergent and criterion validity, of the MSI-BPD in an effort to establish the clinical utility of the MSI-PBD as a screening measure for BPD in inpatient adolescents. A total of 121 adolescents from an acute care inpatient unit were recruited for the study. Convergent validity was examined with established measures of BPD in adolescents, including the use of receiver operating characteristics analyses to establish a clinical cutoff score for the MSI-BPD in predicting a diagnosis of BPD. Criterion validity was examined by using this clinical cutoff to investigate group differences in suicidal ideation and Axis I symptoms, known correlates of BPD. Findings demonstrated support for validity of the MSI-BPD when used among inpatient adolescents, and established a clinical cutoff of 5.5. Taken together, this study demonstrates adequate validity for the MSI-BPD, and suggests it is a valuable screening measure for BPD in adolescent inpatients.
