The Development of the Five-Factor Schizoid Inventory.

The current study sought to provide evidence for a measure of schizoid personality disorder (SZD PD) traits using the Five-Factor Model framework of personality. In the first study, undergraduate participants (n = 496) completed the Five-Factor Schizoid Inventory (FFZI) and other self-report measures. The first half of the sample was used to develop the FFZI, while the second half was used to validate it. The FFZI demonstrated excellent internal consistency, convergent validity with measures of SZD PD and hypothesized IPIP-NEO facets, and discriminant validity with other PDs and non-hypothesized IPIP-NEO facets. The second study recruited MTurk participants (n = 181) and demonstrated preliminary support for the reliability and validity of the FFZI in an online, community sample. Ultimately, these data suggest that the FFZI is a useful measure of SZD PD and provide further evidence that SZD PD can be conceptualized as a maladaptive extension of introversion traits.

Prevalence rate trends of borderline personality disorder symptoms and self-injurious behaviors in college students from 2017 to 2021.

The current study examines the prevalence rates of borderline personality disorder (BPD) symptoms and nonsuicidal self-injury (NSSI) behaviors amongst college students over a five-year period, including pre- and during the COVID pandemic. Online prescreener surveys were completed by undergraduate students (n = 12,756) attending a large Southern Plains University every semester from Spring of 2017 to Spring of 2021. The percentage of students with NSSI history and significant BPD symptoms were visualized by semester to examine trends over time. A series of logistic regressions and negative binomial regressions were conducted on NSSI history and BPD symptoms to examine whether the endorsement rates have been increasing over time and to compare before and during COVID pandemic. There was an increasing trend of NSSI rates and significant BPD symptoms over time for all sexes. Furthermore, there was a steeper increase in BPD symptoms specifically in female students over the last five years. Additionally, there was a significant increase in odds of elevated BPD symptoms and NSSI behaviors in the college students enrolled during the COVID pandemic compared with pre-COVID. Overall, there has been an increasing trend in BPD symptoms and NSSI rates over the last few years, including during the COVID pandemic.

Pathways to Health Reported by Patients With Borderline Personality Disorder With a Good Overall Outcome Versus a Fair-Poor Outcome Over 24 Years of Prospective Follow-Up.

Our objective was to determine pathways to health reported by patients with borderline personality disorder (BPD) who had and had not attained a good overall outcome over 24 years of prospective follow-up. Overall outcome symptomatically and psychosocially and 11 pathways to health related to vocation, relationships, activities, and psychiatric treatment that patients reported were helpful to their functioning or feeling better about themselves were assessed at 12 contiguous 2-year follow-up periods using a semistructured interview. Good outcome patients reported significantly higher rates of pathways related to work performance, relationships with friends, relationship with a partner/spouse, and athletic activities. In contrast, patients with a fair-poor outcome reported significantly higher rates of psychotherapy and psychotropic medication as pathways. Taken together, the results of this study suggest that a good overall outcome is significantly associated with reported vocational, interpersonal, and activity pathways, while a fair-poor outcome is significantly associated with reported treatment-related pathways.

Parental Reports of Physically Self-Destructive Behavior in the Offspring of Patients With Borderline Personality Disorder and Other Personality Disorders.

The main aim of this article is to compare the prevalence of four forms of physically self-destructive behavior in the offspring of parents with borderline personality disorder (BPD) and compare them to the offspring of parents with other personality disorders (OPD). At the 4- and 6-year waves in a prospective study of the long-term course of BPD, participants were asked to report on the self-destructive behaviors of their children using the Childhood Self-Destructiveness Scale. A total of 68 parents were interviewed regarding 131 children, 104 of whom were offspring of parents with BPD (n = 55) and 27 were offspring of parents with OPD (n = 13). BPD parents reported significantly more self-injury and substance abuse in their children than OPD parents. The results from this study suggest that both direct and indirect forms of self-destructive behavior are both more common and quite specific for the children of parents with BPD.

Symptomatic Disorders in Adults and Adolescents With Borderline Personality Disorder.

Symptomatic disorders often co-occur with borderline personality disorder (BPD). This study's purpose was to compare the rates of comorbidity reported by adult and adolescent inpatients with BPD, including complex comorbidity (i.e., a combination of disorders of affect and impulsivity). One hundred four adolescents (aged 13-17) and 290 adults (aged 18-35) with BPD were interviewed using an age-appropriate semistructured interview for the assessment of symptomatic disorders. Lifetime rates of mood disorders and ADHD were quite similar for the two study groups. However, rates of anxiety disorders, including PTSD, substance use disorders, eating disorders, and complex comorbidity were significantly higher among adults than adolescents. Taken together, the results of this study suggest that broadly defined disorders of both affect and impulsivity are more common among adults than adolescents with BPD. They also suggest that a pattern of complex comorbidity is even more distinguishing for these two groups of borderline patients.

Affective and Behavioral Characteristics of Adolescent and Adult Borderline Personality Disorder.

Adults with borderline personality disorder (BPD) report greater affective lability, impulsivity, and aggression compared to same-age peers, but no studies have examined whether these findings are replicable among adolescents with BPD and their peers, or whether adolescents and adults with BPD report symptoms of comparable severity. One hundred and one adolescent (age 13-17) BPD inpatients and 60 age-matched, psychiatrically healthy adolescents completed self-report measures for affective lability, impulsivity, and aggression. Comparison samples included 29 and 41 adult outpatients with BPD and 127 community adults with BPD. Adolescents with BPD reported greater severity of all symptoms except nonplanning impulsiveness compared to peers. They reported similar symptom severity to adults but reported less severe verbal aggression and anger. Adolescents with BPD are distinguishable from typically developing adolescents on self-reported, dimensional affective and behavioral symptom measures, and may experience these symptoms at comparable severity to adult counterparts.

Sexual Orientation and Gender of Intimate Relationship Partners Among Adolescents With BPD and Psychiatrically Healthy Adolescents.

The first aim of this study was to describe reported sexual orientation in a group of adolescents diagnosed with borderline personality disorder compared to a group of psychiatrically healthy adolescents. The second purpose was to compare data on dating and gender of dating partners in the same two groups. Two semistructured interviews, which assessed sexual orientation, dating history, and gender of dating partners, were administered to 104 borderline adolescents and 60 psychiatrically healthy comparison subjects. Borderline adolescents were significantly more likely than comparison subjects to report having a gay/lesbian/bisexual orientation. They also were significantly more likely to date and to report dating a same-gender partner or same- and other-gender partners than comparison subjects. The results of this study suggest that same-gender attraction and/or intimate relationships may be an important interpersonal issue for approximately one-third of adolescents with BPD.

Risk Factors for Borderline Personality Disorder in Adolescents.

The objective of this study was to assess the association between variables reflecting childhood adversity, protective childhood experiences, and the five-factor model of personality and BPD in adolescents. Two groups of adolescents were studied: 104 met criteria for BPD and 60 were psychiatrically healthy. Adverse and protective childhood experiences were assessed using a semistructured interview. The five-factor model of personality was assessed using the NEO-FFI. Eight of nine variables indicating severity of abuse and neglect, positive childhood relationships, childhood competence, and the personality factors studied were found to be significant bivariate risk factors for adolescent BPD. However, in a multivariate model, severity of neglect, higher levels of neuroticism, and lower levels of childhood competence were found to be the best risk factor model. Taken together, the results of this study suggest that all three types of risk factors studied are significantly associated with BPD in adolescents.

The 24-year course of major depression in patients with borderline personality disorder and personality-disordered comparison subjects.

BACKGROUND: This study had two main objectives. The first was to detail the prevalence of major depressive disorder over 24 years of follow-up for both patients with borderline personality disorder (BPD) and comparison subjects with other personality disorders (OPD). The second was to determine time-to-remission, recurrence, and new onset of major depression among these two groups of patients. METHODS: The SCID-I was administered to 290 borderline inpatients and 72 personality-disordered comparison subjects during their index admission. It was also re-administered at 12 contiguous two-year follow-up periods. RESULTS: The prevalence of major depression was significantly higher for borderline patients over time but declined significantly over time for those in both study groups. In terms of time to events, 93% of borderline patients meeting criteria for major depression at baseline experienced a two-year remission by the time of the 24-year follow-up. Recurrences were about as common (90% for those with remitted major depression). New onsets of major depression were also very common (86% for those without major depression during their index admission). LIMITATIONS: Results may not pertain to less severely ill patients with BPD and those in less treatment. CONCLUSIONS: Taken together, the results of this study suggest that the remitting-recurring course of major depression in borderline patients is very similar to the course of major depression in those with other types of personality disorder and those for whom major depression is their primary disorder.

Facets of identity disturbance reported by patients with borderline personality disorder and personality-disordered comparison subjects over 20 years of prospective follow-up.

This study had two objectives. The first was to determine the levels of identity disturbance reported by 290 patients with borderline personality disorder (BPD) and 72 personality-disordered comparison subjects over 20 years of prospective follow-up. The second aim was to describe the levels of identity disturbance reported by 152 ever recovered vs. 138 never recovered borderline patients over 20 years of prospective follow-up. Participants were followed and re-assessed every two years for a total of 20 years of follow-up. Borderline patients reported levels of these states that were more than three times higher than personality-disordered comparison subjects, with both groups demonstrating significant declines in these states over time. For three of these inner states ("I feel like I am worthless," "I feel like a complete failure," and "I feel like I am evil"), recovered borderline patients had lower baseline scores and significantly different patterns of decline than non-recovered patients. For the fourth state, "I feel like I am a bad person," recovered patients had lower scores over time, but the groups declined at the same rate. These results suggest that borderline patients report experiencing inner states related to having a negative identity less often over time. Additionally, recovery status is significantly associated with decreased time experiencing these states.
