An Evaluation of the Contextual Factors Associated with the Use of Either Tobacco or Electronic Cigarettes in Individuals who Dual Use.

INTRODUCTION: Little is known about patterns of dual use of tobacco and electronic cigarettes (e-cigarettes), especially regarding the factors that lead people to choose either product in particular situations. Identifying contextual factors that are associated with product use would enhance understanding of the maintenance of dual product use. METHODS: Individuals who dual use (N=102) completed ecological momentary assessment surveys via text message regarding recent use of tobacco and e-cigarettes for two weeks. Product legality, availability, craving, the presence of other people who smoke/vape, and social disapproval were assessed. Data were analyzed using hierarchical logistic regression to identify factors associated with likelihood of tobacco versus e-cigarette use. RESULTS: Contexts associated with increased likelihood of using tobacco rather than e-cigarettes included being in the presence of other people who smoke (OR=2.74, p<.0001) and experiencing elevated tobacco cigarette craving (OR=3.51, p<.0001). Decreased likelihood of tobacco over e-cigarette use was associated with smoking restrictions (OR=0.26, p=.003), the presence of other people who vape (OR=0.46, p<.0001), and experiencing elevated e-cigarette craving (OR=0.23, p<.0001). The legality of e-cigarettes, social disapproval, and the availability of the alternative product were not significantly associated with use of one product over the other. An individual difference score of relative tobacco (vs. e-cigarette) use pattern did not significantly moderate these effects. CONCLUSIONS: This study provided essential information regarding behavioral patterns of dual use, which informs our understanding of people who dual use. Contexts such as smoking restrictions, craving, and social context significantly differentiated between use of tobacco and e-cigarettes. This suggests product-specific motivations for dual use of tobacco and e-cigarettes in people who use both. IMPLICATIONS: This study assessed the relationship between momentary contextual factors and dual use in a nationally recruited sample of people who dual use. Assessments of dual use in daily life provided novel information regarding patterns of dual use as well as differential use-motivations for each product. This information will be essential to build a theoretical framework of dual use of tobacco and e-cigarettes.

An Examination of Objective and Self-Report Measures of Ad Libitum Electronic Cigarette Use: Identifying Patterns of Puffing Behavior and Evaluating Self-Report Items.

INTRODUCTION: There has been little research objectively examining use-patterns among individuals who use electronic cigarettes (e-cigarettes). The primary aim of this study was to identify patterns of e-cigarette use and categorize distinct use-groups by analyzing patterns of puff topography variables over time. The secondary aim was to identify the extent to which self-report questions about use accurately assess e-cigarette use-behavior. AIMS AND METHODS: Fifty-seven adult e-cigarette-only users completed a 4-hour ad libitum puffing session. Self-reports of use were collected both before and after this session. RESULTS: Three distinct use-groups emerged from exploratory and confirmatory cluster analyses. The first was labeled the "Graze" use-group (29.8% of participants), in which the majority of puffs were unclustered (ie, puffs were greater than 60 seconds apart) with a small minority in short clusters (2-5 puffs). The second was labeled the "Clumped" use group (12.3%), in which the majority of puffs were within clusters (short, medium [6-10 puffs], and/or long [>10 puffs]) and a small minority of puffs were unclustered. The third was labeled the "Hybrid" use-group (57.9%), in which most puffs were either within short clusters or were unclustered. Significant differences emerged between observed and self-reported use-behaviors with a general tendency for participants to overreport use. Furthermore, commonly utilized assessments demonstrated limited accuracy in capturing use behaviors observed in this sample. CONCLUSIONS: This research addressed several limitations previously identified in the e-cigarette literature and collected novel data that provided substantial information about e-cigarette puff topography and its relationship with self-report measures and use-type categorization. IMPLICATIONS: This is the first study to identify and distinguish three empirically based e-cigarette use-groups. These use-groups, as well as the specific topography data discussed, can provide a foundation for future research assessing the impact of use across different use types. Furthermore, as participants tended to overreport use and assessments did not capture use accurately, this study can serve as a foundation for future work developing more appropriate assessments for use in research studies as well as clinical practice.

A smartphone-based intervention for young people who self-harm ('PRIMARY'): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Self-harm in young people is a public health concern connected with severe mental health problems, such as personality pathology. Currently, there are no specific evidence-based interventions available for young people who self-harm. Therefore, we developed PRe-Intervention Monitoring of Affect and Relationships in Youth (PRIMARY), a smartphone-based intervention, co-designed by clinicians and young people with lived experience of mental ill-health. PRIMARY combines the Experience Sampling Method (ESM) with weekly report sessions. The study aims to examine the effectiveness of PRIMARY with regard to reducing self-harm, and improving emotion regulation and quality of relationships. METHODS: This study is a multicenter, parallel groups, randomized controlled trial (RCT) comparing the PRIMARY intervention to a waiting list control group. PRIMARY comprises 28 consecutive days of questionnaires five times each day (i.e., ESM) and four weekly report sessions. Participants will comprise 180 young people referred for treatment to the participating Dutch mental healthcare institutions and (1) are aged 12 to 25 years, and (2) engaged in ≥ 1 act of self-harm in the past year. Participants are randomly allocated to a study group after screening in a 1:1 ratio by an independent researcher using computer-generated randomization sequences with stratified block randomization by age (12 to 15 years / 16 to 25 years). Staff will conduct assessments with all participants at baseline (Wave 1), after 28 days (Wave 2), and in a subsample after 10 weeks of subsequent specialized treatment (Wave 3). The primary outcomes are self-harm, emotion regulation, and quality of relationships. Secondary outcomes include patient and clinician satisfaction. Exploratory analyses of ESM data will examine the relationship between emotions, social relationships, and self-harm. DISCUSSION: The results of this trial will clarify whether an innovative smartphone-based intervention is effective for reducing self harm and improving emotion regulation and the quality of social relationships. It has the potential to fill a treatment gap of interventions specifically targeting self-harm. If proven effective, it would provide an accessible, easy-to-implement, low-cost intervention for young people. Furthermore, the ESM-data will allow detailed analyses into the processes underlying self-harm, which will contribute to theoretical knowledge regarding the behavior. TRIAL REGISTRATION: ISRCTN42088538 ( https://doi.org/10.1186/ISRCTN42088538 ), retrospectively registered on the 26th of October 2022.

Neighbourhood characteristics and the treated incidence rate of borderline personality pathology among young people.

OBJECTIVE: The impact of the wider social environment, such as neighbourhood characteristics, has not been examined in the development of borderline personality disorder. This study aimed to determine whether the treated incidence rate of full-threshold borderline personality disorder and sub-threshold borderline personality disorder, collectively termed borderline personality pathology, was associated with the specific neighbourhood characteristics of social deprivation and social fragmentation. METHOD: This study included young people, aged 15-24 years, who attended Orygen's Helping Young People Early programme, a specialist early intervention service for young people with borderline personality pathology, from 1 August 2000-1 February 2008. Diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Personality Disorders, and census data from 2006 were used to determine the at-risk population and to obtain measures of social deprivation and fragmentation. RESULTS: The study included 282 young people, of these 78.0% (n = 220) were female and the mean age was 18.3 years (SD = ±2.7). A total of 42.9% (n = 121) met criteria for full-threshold borderline personality disorder, and 57.1% (n = 161) had sub-threshold borderline personality disorder, defined as having three or four of the nine Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) borderline personality disorder criteria. There was more than a sixfold increase in the treated incidence rate of borderline personality pathology in the neighbourhoods of above average deprivation (Quartile 3) (incidence rate ratio = 6.45, 95% confidence interval: [4.62, 8.98], p < 0.001), and this was consistent in the borderline personality disorder sub-groups. This association was also present in the most socially deprived neighbourhood (Quartile 4) (incidence rate ratio = 1.63, 95% confidence interval: [1.10, 2.44]), however, only for those with sub-threshold borderline personality disorder. The treated incidence of borderline personality pathology increased incrementally with the level of social fragmentation (Quartile 3: incidence rate ratio = 1.93, 95% confidence interval: [1.37, 2.72], Quartile 4: incidence rate ratio = 2.38, 95% confidence interval: [1.77, 3.21]). CONCLUSION: Borderline personality pathology has a higher treated incidence in the more socially deprived and fragmented neighbourhoods. These findings have implications for funding and location of clinical services for young people with borderline personality pathology. Prospective, longitudinal studies should examine neighbourhood characteristics as potential aetiological factors for borderline personality pathology.

A randomised controlled trial of a psychoeducational group intervention for family and friends of young people with borderline personality disorder features.

OBJECTIVE: Preliminary evidence indicates that interventions designed to support family and friends ('carers') of young people with early-stage borderline personality disorder effectively improve carer outcomes. None of these interventions have been tested in a randomised controlled trial. METHOD: This clustered, partially nested, randomised controlled trial was conducted at Orygen, Melbourne, Australia. Carers of young people (aged 15-25 years) with borderline personality disorder features were randomly assigned as a unit in a 1:1 ratio, balanced for young person's sex and age, to receive a 15-day intervention comprising: (1) the three-session, in-person, Making Sense of BPD (MS-BPD) multi-family group programme, plus two self-directed online psychoeducational modules (MS-BPD + Online, n = 38), or (2) the two self-directed online psychoeducational modules alone (Online, n = 41). The primary outcome was 'negative experiences of care', measured with the Experience of Caregiving Inventory, at the 7-week endpoint. RESULTS: A total of 79 carers were randomised (pool of 281, 197 excluded, 94 declined) and 73 carers (51 females [69.9%], Mage = 43.8 years [standard deviation, SD = 12.9], MS-BPD + Online n = 35 [47.9%], Online n = 38 [52.1%]) provided follow-up data and were included in the intent-to-treat analysis. The intent-to-treat (and per protocol) analyses did not find any significant differences between the groups on the primary (d = -0.32; 95% confidence interval = [-17.05, 3.97]) or secondary outcomes. Regardless of treatment group, caregivers improved significantly in their personality disorder knowledge. CONCLUSION: Delivering MS-BPD in conjunction with an online psychoeducational intervention was not found to provide additional benefit over and above access to an online intervention alone. In accordance with national guidelines, carer interventions should be routinely offered by youth mental health services as part of early intervention programmes for borderline personality disorder. Further research is warranted into which interventions work for whom, carers' preferences for support and barriers to care.

A Comparison of Adolescent versus Young Adult Outpatients with First-Presentation Borderline Personality Disorder: Findings from the MOBY Randomized Controlled Trial.

OBJECTIVE: The increasing focus on adolescent personality disorder has tended to ignore evidence of the developmental continuity of the period from puberty to young adulthood. This study aims to: (1) describe the characteristics of a sample of young people with borderline personality disorder (BPD) who had no previous history of evidence-based treatment for the disorder and (2) compare their characteristics by participant age group. METHODS: One hundred and thirty-nine young people (15 to 25 years) with BPD, newly enrolled in the Monitoring Outcomes of BPD in Youth randomized controlled trial, completed semi-structured interview and self-report measures assessing demographic, clinical, and functional characteristics. Younger (aged 15 to 17 years; n = 64) and older (aged 18 to 25 years; n = 75) participants were compared on these same variables using t-tests, chi-square tests, and logistic regression. RESULTS: Young outpatients with BPD had extensive and severe psychopathology and were functioning poorly. Adolescents and young adults with BPD showed substantial similarities on 20 key aspects of their presentation. Significant between-groups differences were observed in household makeup, treatment history, antisocial personality disorder, emotion dysregulation, substance use, age of commencement and extent of self-harm, and achievement of age-appropriate educational milestones. Adolescent BPD group membership was predicted by family composition and self-harm, whereas young adult BPD group membership was predicted by not achieving age-appropriate milestones, vocational disengagement, and emotion dysregulation. The final model explained 54% of the variance and correctly classified 80.2% of the sample by age. CONCLUSIONS: Both adolescents and young adults with early stage BPD present with severe and often similar problems to one another, supporting developmental continuity across this age range. However, there are also meaningful differences in presentation, suggesting that pathways to care might differ by age and/or developmental stage. Detection and intervention for personality disorder should not be delayed until individuals reach 18 years of age.

A comparison of experiences of care and expressed emotion among caregivers of young people with first-episode psychosis or borderline personality disorder features.

OBJECTIVE: Caregivers of individuals with severe mental illness often experience significant negative experiences of care, which can be associated with higher levels of expressed emotion. Expressed emotion is potentially a modifiable target early in the course of illness, which might improve outcomes for caregivers and patients. However, expressed emotion and caregiver experiences in the early stages of disorders might be moderated by the type of severe mental illness. The aim was to determine whether experiences of the caregiver role and expressed emotion differ in caregivers of young people with first-episode psychosis versus young people with 'first-presentation' borderline personality disorder features. METHOD: Secondary analysis of baseline (pre-treatment) data from three clinical trials focused on improving caregiver outcomes for young people with first-episode psychosis and young people with borderline personality disorder features was conducted (ACTRN12616000968471, ACTRN12616000304437, ACTRN12618000616279). Caregivers completed self-report measures of experiences of the caregiver role and expressed emotion. Multivariate generalised linear models and moderation analyses were used to determine group differences. RESULTS: Data were available for 265 caregivers. Higher levels of negative experiences and expressed emotion, and stronger correlations between negative experiences and expressed emotion domains, were found in caregivers of young people with borderline personality disorder than first-episode psychosis. Caregiver group (borderline personality disorder, first-episode psychosis) moderated the relationship between expressed emotion and caregiver experiences in the domains of need to provide backup and positive personal experiences. CONCLUSION: Caregivers of young people with borderline personality disorder experience higher levels of negative experiences related to their role and expressed emotion compared with caregivers of young people with first-episode psychosis. The mechanisms underpinning associations between caregiver experiences and expressed emotion differ between these two caregiver groups, indicating that different supports are needed. For borderline personality disorder caregivers, emotional over-involvement is associated with both negative and positive experiences, so a more detailed understanding of the nature of emotional over-involvement for each relationship is required to guide action.

A Meta-Analysis of Cue Reactivity in Tobacco Cigarette Smokers.

INTRODUCTION: The cue reactivity paradigm allows for systematic evaluation of motivational responses to drug-related cues that may elicit drug use. The literature on this topic has grown substantially in recent decades, and the methodology used to study cue reactivity has varied widely across studies. The present research provided a meta-analytic investigation of variables that have an impact on cue reactivity effects to enhance our understanding of this key feature of tobacco use disorders. METHODS: A total of 128 publications yielded 249 effect sizes, which were analyzed to investigate the magnitude of the cue reactivity effect and potential moderators. RESULTS: Craving generated a moderate-to-large effect size (Hedges' g = 0.71, p < .001), indicating that drug cues produced significantly greater craving than neutral cues. However, physiological variables yielded significantly lower or nonsignificant effect sizes. Analyses of a variety of empirically and theoretically relevant moderator variables showed that cue modality, cue personalization, cue reactivity environment, and the use of multiple assessments of cue reactivity were significantly associated with the magnitude of cue-specific craving effects (ps < .001). Effect sizes were not significantly related to abstinence status, gender, cigarettes per day, and treatment-seeking status. CONCLUSIONS: The results underscored the strength of self-reported craving as an index of cue reactivity across studies, which support theories that posit cue reactivity is core to the addictive process for daily tobacco cigarette smokers. The present research further elucidates the variables that alter the cue reactivity effects across studies and provides recommendations for future cue reactivity research. IMPLICATIONS: A core feature of addiction is that drug-related cues can have a major impact on motivational responses across multiple substance use disorders, including tobacco cigarettes. This paper describes a meta-analysis updating and synthesizing cue reactivity research with tobacco cigarette smokers over the last 20 years, a time of rapid growth for this literature. The study leads to a better understanding of the cue reactivity paradigm across different self-report and physiological variables and identifies factors that may modulate addictive motivation for tobacco cigarettes.

Diagnosis and Treatment of Borderline Personality Disorder in Young People.

PURPOSE OF REVIEW: We review recent research concerning the diagnosis and treatment of borderline personality disorder (BPD) in young people. We examine evidence for the need to define an appropriate age for detection, and the suitability of current classification methods and treatment. RECENT FINDINGS: Evidence supports early detection and intervention for subsyndromal borderline pathology or categorical BPD across an extended developmental period. A range of structured treatments are effective for BPD in young people, although the role of treatment components in successful outcomes is unclear. Substantial evidence suggests that a stronger focus on functional outcomes, especially social and vocational outcomes, is warranted. Effective treatments for BPD are rarely available internationally. There is a need to assess whether less complex interventions might be developed that are scalable across health systems. A clinical staging model should be considered, addressing clinical distress and co-occurring psychopathology, as well as diagnosis.

Testing the Interpersonal-Cognitive Model of Auditory Verbal Hallucinations in Youths with Either Early-Stage Borderline Personality Disorder or First-Episode Schizophrenia Spectrum Disorder.

This is the first study to explore interpersonal schemata in outpatient youths (age 15-25 years) with early-stage borderline personality disorder (BPD) and auditory verbal hallucinations (AVH). It also aimed to replicate, in a transdiagnostic youth sample, the finding from studies of adults with AVH that negative beliefs about the self and others lead to negative appraisals of voices, which in turn elicits depression. The following 3 groups were compared: youth with BPD+AVH (n = 23), youth with schizophrenia spectrum disorder (SZ) with AVH (SZ+AVH, n = 20), and youths with BPD who did not experience AVH (BPD no AVH, n = 23). The BPD+AVH group reported more negative and fewer positive self schemata than the SZ+AVH group. They also saw themselves as being more socially inferior to others than did the SZ+AVH group, but they did not differ in appraisals of self or others, compared with the BPD no AVH group. In youths with AVH (BPD+AVH, SZ+AVH combined), the indirect effect of beliefs about self or others, via negative appraisals of voices on depression, was not significant. Instead, a significant indirect effect of negative appraisals of voices on depression, via negative beliefs about self, was found. The experience of AVH during adolescence and young adulthood, when the identity is still being formed, might have a more profound effect on the developing self than during later adulthood, when the self is more stable and resilient. Negative self-appraisals might constitute a treatment target for early intervention for youths with distressing voices, including those with BPD.

Does a Therapist's World View Matter?

While past research indicates that mental health professionals are less religious than the public they serve, little is known about the implications of therapists' world views for their practice. In this study, approximately 50 therapists completed surveys that assessed self-identification in relation to spirituality, religion, and/or world view; how relevant they considered their patients' and their own world views; and responses to clinical vignettes involving issues arising in treatment. While a minority considered themselves religious, a majority indicated that they considered themselves moderately or very spiritual. When asked how they would respond to a series of clinical vignettes involving topics such as assisted suicide and encouraging the use of spiritual resources, responses varied significantly by world view. Respondents endorsed several factors limiting the integration of religion/spiritualities/world views into their clinical work. These data raise questions about how to further explore the clinical relevance of the therapist's world view.

The predictive validity of bipolar at-risk (prodromal) criteria in help-seeking adolescents and young adults: a prospective study.

OBJECTIVES: There are no established tools to identify individuals at risk for developing bipolar disorder. We developed a set of ultra-high-risk criteria for bipolar disorder [bipolar at-risk (BAR)]. The primary aim of the present study was to determine the predictive validity of the BAR criteria. METHODS: This was a 12-month prospective study that was conducted at Orygen Youth Health Clinical Program, a public mental health program for young people aged 15-24 years in metropolitan Melbourne, Australia. At intake, BAR screen-positive individuals and a matched group of individuals who did not meet BAR criteria were observed over a period of 12 months. The BAR criteria include general criteria such as being in the peak age range for the onset of the disorder, as well as sub-threshold mania, depression plus cyclothymic features, and depression plus genetic risk. Conversion to first-episode mania/hypomania was defined by the presence of DSM-IV manic symptoms for more than four days, in line with the DSM-IV definition of hypomania/mania. RESULTS: A total of 559 help-seeking patients were screened. Of the eligible participants, 59 (10.6%) met BAR criteria. Thirty-five participants were included in the BAR group and 35 matched participants were selected to be in the control group. During the follow-up, five BAR patients out of 35 (14.3%) converted to first-episode hypomania/mania as opposed to none in the non-BAR group [χ(2) (1) = 5.38, p = 0.020]. Four out of these five converters had a DSM-IV diagnosis of bipolar I or bipolar II disorder. CONCLUSIONS: These findings support the possibility of identification of persons prior to the onset of mania/hypomania. The proposed criteria need further evaluation in larger, prospective studies with longer follow-up periods.

An analysis of real-time suicidal ideation and its relationship with retrospective reports among young people with borderline personality disorder.

INTRODUCTION: This study aimed to analyze the real-time variability of suicidal ideation intensity and the relationship between real-time and retrospective reports of suicidal ideation made on the Beck Scale for Suicidal Ideation (BSS), among young people with borderline personality disorder (BPD). METHODS: Young people (15-25-year olds) with BPD (N = 46), recruited from two government-funded mental health services, rated the intensity of their suicidal ideation six times per day for 7 days before completing the BSS. RESULTS: For 70% of participants, suicidal ideation changed in intensity approximately five times across the week, both within and between days. BSS ratings were most highly correlated with the highest real-time ratings of suicidal ideation. However, this was not significantly different from the relationship between the BSS and both the average and most recent ratings. Median ratings of suicidal ideation intensity were higher on the BSS compared with an equivalent question asked in real time. CONCLUSION: Findings suggest that young people with BPD experience high levels of fluctuation in their intensity of suicidal ideation across a week and that retrospective reports of suicidal ideation might be more reflective of the most intense experience of suicidal ideation across the week.

Psychopathology and psychosocial functioning among young people with first-episode psychosis and/or first-presentation borderline personality disorder.

BACKGROUND: One in five young people with first-episode psychosis (FEP) also presents with borderline personality disorder (BPD) features. Among people diagnosed with BPD, auditory verbal hallucinations occur in 29-50 % and delusions in 10-100 %. Co-occurrence of psychotic symptoms and BPD is associated with greater clinical severity and greater difficulty accessing evidence based FEP care. This study aimed to investigate psychotic symptoms and psychosocial functioning among young people presenting to an early intervention mental health service. METHOD: According to the presence or absence of either FEP or BPD, 141 participants, aged 15-25 years, were assigned to one of four groups: FEP, BPD, combined FEP + BPD, or clinical comparison (CC) participants with neither FEP nor BPD. Participants completed semi-structured diagnostic interviews and interviewer and self-report measures of psychopathology and psychosocial functioning. RESULTS: The FEP + BPD group had significantly more severe psychopathology and poorer psychosocial functioning than the FEP group on every measure, apart from intensity of hallucinations. Comparing the FEP or BPD groups, the BPD group had greater psychopathology, apart from intensity of psychotic symptoms, which was significantly greater in the FEP group. These two groups did not significantly differ in their overall psychosocial functioning. Compared with CC young people, both the FEP + BPD and BPD groups differed significantly on every measure, with medium to large effect sizes. CONCLUSIONS: Young people with co-occurring FEP and BPD experience more severe difficulties than young people with either diagnosis alone. This combination of psychosis and severe personality pathology has been longitudinally associated with poorer outcomes among adults and requires specific clinical attention.

Associations of state or trait dissociation with severity of psychopathology in young people with borderline personality disorder.

BACKGROUND: State and trait dissociation are associated with borderline personality disorder (BPD) severity and severity of commonly co-occurring mental health symptoms. Although these distinct constructs do not consistently co-occur in experimental settings, they are frequently reported as the same construct, namely dissociation. This study aimed to investigate the co-occurrence of state and trait dissociation among young people with BPD and to examine whether state or trait dissociation were associated with symptom severity in this population. METHODS: State dissociation was induced using a stressful behavioural task in a clinical sample of 51 young people (aged 15-25 years) with three or more BPD features. Diagnoses, state and trait dissociation, BPD severity and severity of posttraumatic stress disorder (PTSD), depressive, and stress symptoms were assessed by self-report or research interview. RESULTS: A chi-square test of independence showed a strong association between state and trait dissociation. Bonferroni corrected t-tests showed that state dissociation was significantly associated with PTSD symptom severity and likely associated with BPD severity and severity of depressive and stress symptoms. Trait dissociation was not associated with symptom severity or severity of BPD features. CONCLUSIONS: These findings highlight the need to distinguish between state and trait dissociation in personality disorder research. They suggest that state dissociation might be an indicator of higher severity of psychopathology in young people with BPD.

Emotion dysregulation in young people with borderline personality disorder: One pattern or distinct subgroups?

Emotion dysregulation is a key feature of borderline personality disorder (BPD). Given the heterogeneity of BPD and emotion regulation, this study sought to define subgroups among a sample of young people with BPD based on their pattern of emotion regulation abilities. Baseline data from the Monitoring Outcomes of BPD in Youth (MOBY) clinical trial were used, in which 137 young people (Mage = 19.1, SDage = 2.8; 81% female) completed the self-report Difficulties in Emotion Regulation Scale (DERS), as a measure of emotion regulation abilities. Latent profile analysis (LPA) was conducted to identify subgroups, based upon response patterns on the six DERS subscales. Subsequent analysis of variance and logistic regression models were used to characterize the identified subgroups. LPA revealed three subgroups. A "low and unaware" (n = 22) subgroup, reporting the least emotion dysregulation, apart from high emotional unawareness. A "moderate and accepting" subgroup (n = 59), reporting high emotional acceptance within its own pattern, and moderate emotion dysregulation compared with the other subgroups. A "high and aware" subgroup (n = 56), reporting the highest level of emotion dysregulation, but with high emotional awareness. Some demographic, psychopathology, and functioning characteristics were associated with subgroup membership. The identification of distinct subgroups highlights the importance of considering the level of emotional awareness in the context of other regulatory abilities and suggests that therapies should not take a "one-size-fits-all" approach to emotion dysregulation. Future research should seek to replicate the identified subgroups given the relatively small sample size in the current study. In addition, examining the stability of subgroup membership and the influence upon treatment outcome will be interesting avenues for further exploration.

Bipolar At-Risk Criteria and Risk of Bipolar Disorder Over 10 or More Years.

Importance: Predicting the onset of bipolar disorder (BD) could facilitate preventive treatments. Among risk measures, bipolar at-risk (BAR) criteria have shown promise in predicting onset of bipolar disorder in the first year in clinical cohorts; however, it is not known whether BAR criteria are associated with the onset of BD in the longer term. Objective: To assess the association of BAR criteria with onset of BD over 10 to 13 years follow-up. Design, Setting, and Participants: This prospective cohort study, completed between May 1, 2020, and November 7, 2022, included consenting people seeking help for nonpsychotic major mental health difficulties, including mood, personality, and substance use disorders, who were originally recruited at ages 15 to 25 years from a tertiary youth mental health setting in metropolitan Melbourne, Victoria, Australia, from May 1, 2008, to September 30, 2010. Exposure: Meeting BAR criteria at baseline. Criteria included subthreshold mania, cyclothymic features, subthreshold depression, and family history of BD. A matched clinical comparison group was recruited from the same help-seeking population. Main Outcomes and Measures: The primary outcome was expert consensus diagnosis of BD I or II based on the Mini International Neuropsychiatric Interview, self-reported information collected through online assessments, and linked data on mental health service utilization in Victoria over 10 to 13 years of follow-up. Results: Among 69 eligible participants, follow-up data were available for 60 (88.2%). The mean (SD) age at the end of follow-up was 32.9 (2.8) years, and 49 (81.7%) were women. A total of 28 participants met BAR criteria, and 32 were in the comparison group. In the BAR group, 8 patients (28.6%) developed BD over a mean (SD) of 11.1 (0.7) years of follow-up, and no patients in the comparison group developed BD. The risk of developing BD was higher in the BAR group than in the non-BAR group (χ21 = 70.0; P < .001). The proportions of transitions to BD were equal in the first and second halves of the follow-up period. Conclusions and relevance: In this cohort study of participants seeking care for mental health difficulties, patients meeting the BAR criteria were significantly more likely to transition to BD over a decade after ascertainment compared with patients not meeting the BAR criteria. The findings suggest that those meeting BAR criteria may benefit from longer-term monitoring and support. Evaluation of predictive properties in longer-term studies using a risk measure will help with implementation of BAR criteria in clinical settings.

Young People With Borderline Personality Disorder Have an Increased Lifetime Risk of Being the Victim of Interpersonal Violence.

This study aimed to examine the lifetime risk of being the victim of criminal or violent offenses among young people with borderline personality disorder (BPD) features (1-9 DSM-IV criteria). Demographic and diagnostic data from 492 outpatients who attended a specialist public mental health service for 15- to 25-year-olds between January 1998 and March 2008 were linked with offending data from a state-wide police database, collected between March 1993 and June 2017, in order to establish victimization history. This included information on criminal offenses perpetrated against these young people and intervention orders implemented to protect them from being victimized by another person's violent behavior. Logistic regression analyses, adjusted for sex and co-occurring mental state disorders, were conducted on n = 378 who had complete data (76.5% females). As hypothesized, BPD diagnosis and number of BPD criteria were both significantly associated with an increased risk of being the victim of a violent offense and the complainant of a family violence intervention order. Anger and impulsivity independently predicted a higher risk of being the victim of a violent offense, while unstable relationships, impulsivity, and affective instability independently predicted a higher risk of being the complainant of a family violence intervention order. No significant association was found between BPD and the risk of being the victim of a nonviolent offense. These findings indicate that young people with any BPD features (even below the DSM diagnostic threshold) are at increased risk for victimization by interpersonal violence. Moreover, this risk increases according to the number of BPD criteria. This issue needs to be addressed by prevention and early intervention programs (e.g., by working on self-assertion and interpersonal skills, taking into account the possible influence of previous traumatizing relationship experiences).

Characteristics and Predictors of Educational and Occupational Disengagement Among Outpatient Youth With Borderline Personality Disorder.

This study aimed to investigate predictors of vocational disengagement (referred to as Not in Employment, Education, or Training [NEET]) in young people with borderline personality disorder (BPD). The sample comprised 112 outpatients with a BPD diagnosis, aged 15-25 years, who participated in a randomized controlled trial (ANZCTR12610000100099). The proportion of participants who were NEET (39.3%) at study entry did not improve after 18 months and NEET status frequently changed. Therefore, multinomial regression analyses were used to study three groups: Non-NEET, NEET, and Unstable NEET status. NEET status was predicted by not achieving expected age-appropriate educational milestones, greater instability in identity, and emptiness. Greater instability in interpersonal relationships and identity predicted Unstable NEET status. The findings suggest that specific vocational interventions, that also incorporate a focus on interpersonal functioning, emptiness, and identity disturbance, are needed to improve functioning in youth with BPD, especially when educational milestones are not achieved.

Analyzing Impact of Mouthpiece-based Puff Topography Devices on Smoking Behavior using Wearable Sensors.

Detailed assessment of smoking topography (puffing and post-puffing metrics) can lead to a better understanding of factors that influence tobacco use. Research suggests that portable mouthpiece-based devices used for puff topography measurement may alter natural smoking behavior. This paper evaluated the impact of a portable puff topography device (CReSS Pocket) on puffing & post-puffing topography using a wearable system, the Personal Automatic Cigarette Tracker v2 (PACT 2.0) as a reference measurement. Data from 45 smokers who smoked one cigarette in the lab and an unrestricted number of cigarettes under free-living conditions over 4 consecutive days were used for analysis. PACT 2.0 was worn on all four days. A puff topography instrument (CReSS pocket) was used for cigarette smoking on two random days during the four days of study in the laboratory and free-living conditions. Smoke inhalations were automatically detected using PACT2.0 signals. Respiratory smoke exposure metrics (i.e., puff count, duration of cigarette, puff duration, inhale-exhale duration, inhale-exhale volume, volume over time, smoke hold duration, inter-puff interval) were computed for each puff/smoke inhalation. Analysis comparing respiratory smoke exposure metrics during CReSS days and days without CReSS revealed a significant difference in puff duration, inhale-exhale duration and volume, smoke hold duration, inter-puff interval, and volume over time. However, the number of cigarettes per day and number of puffs per cigarette were statistically the same irrespective of the use of the CReSS device. The results suggested that the use of mouthpiece-based puff topography devices may influence measures of smoking topography with corresponding changes in smoking behavior and smoke exposure.
