Unveiling Adolescent Suicidality: Holistic Analysis of Protective and Risk Factors Using Multiple Machine Learning Algorithms.

Adolescent suicide attempts are on the rise, presenting a significant public health concern. Recent research aimed at improving risk assessment for adolescent suicide attempts has turned to machine learning. But no studies to date have examined the performance of stacked ensemble algorithms, which are more suitable for low-prevalence conditions. The existing machine learning-based research also lacks population-representative samples, overlooks protective factors and their interplay with risk factors, and neglects established theories on suicidal behavior in favor of purely algorithmic risk estimation. The present study overcomes these shortcomings by comparing the performance of a stacked ensemble algorithm with a diverse set of algorithms, performing a holistic item analysis to identify both risk and protective factors on a comprehensive data, and addressing the compatibility of these factors with two competing theories of suicide, namely, The Interpersonal Theory of Suicide and The Strain Theory of Suicide. A population-representative dataset of 173,664 Norwegian adolescents aged 13 to 18 years (mean = 15.14, SD = 1.58, 50.5% female) with a 4.65% rate of reported suicide attempt during the past 12 months was analyzed. Five machine learning algorithms were trained for suicide attempt risk assessment. The stacked ensemble model significantly outperformed other algorithms, achieving equal sensitivity and a specificity of 90.1%, AUC of 96.4%, and AUCPR of 67.5%. All algorithms found recent self-harm to be the most important indicator of adolescent suicide attempt. Exploratory factor analysis suggested five additional risk domains, which we labeled internalizing problems, sleep disturbance, disordered eating, lack of optimism regarding future education and career, and victimization. The identified factors provided stronger support for The Interpersonal Theory of Suicide than for The Strain Theory of Suicide. An enhancement to The Interpersonal Theory based on the risk and protective factors identified by holistic item analysis is presented.

'Everything turned upside down': A thematic analysis of adolescents' experiences of everyday life during COVID-19 restrictions.

BACKGROUND: At the beginning of the COVID-19 pandemic, people were encouraged to practice social distancing, and schools and leisure venues closed. AIMS: We aimed to explore the everyday experiences of Norwegian adolescents during COVID-19 restrictions, when in-person contact with peers was severely limited. METHODS: A total of 622 high-school students (16-18 years of age) replied to an online survey containing open-ended questions about the changes they experienced in everyday life during the first three months of the pandemic. RESULTS: Reflexive thematic analysis resulted in four themes: (a) 'Everyday life turned upside down - everything is on hold'; (b) 'Alone with my thoughts - new concerns'; (c) 'A loss of social life - a fear of wasting important time'; and (d) 'Gratitude - new perspectives in life'. The results are discussed according to mental-health concerns and psychological developmental challenges during adolescence, such as social exploration of roles with peers, autonomy and identity formation during a crisis. CONCLUSIONS: The results underline individual variations and positive experiences among adolescents during the COVID-19 pandemic, despite social restrictions. Still, the lack of in-person contact with friends is related to an increased experience of loneliness and mental-health concerns for many adolescents.

Avoidant and borderline personality disorder patients during the first Covid-19 wave in Norway - a survey-based comparison of therapy changes and patients' accommodations.

BACKGROUND: Patients with personality disorders (PDs) often have insecure attachment patterns and may be especially vulnerable to abrupt treatment changes. Patients with borderline PD (BPD) are often considered vulnerable to treatment interruption due to chronic fear of abandonment. Nonetheless, other PDs are poorly investigated. In the first Covid-19 wave in Norway, in-person treatment facilities and group treatments were strongly restricted from March 12th until May/June 2020. OBJECTIVES: To examine and compare changes in outpatient treatment for patients with avoidant (AvPD) and BPD during the first Covid-19 wave in Norway, and patients' reactions to these changes. METHODS: The study is based on a cross-sectional survey distributed to 1120 patients referred to 12 different PD treatment units on a specialist mental health service level within the Norwegian Network for Personality Disorders. The survey included questions on treatment situation, immediate reactions, and changes during the crisis. From 133 responders (response rate 12%), 40 patients reported BPD and 30 AvPD as diagnosis. RESULTS: All patients were followed up from their therapist after March 12th. Almost all patients in both groups expressed satisfaction under the new circumstances. Both groups experienced the same regularity as before, but more AvPD patients reported less than weekly consultations. AvPD patients reported more negative feelings about changes in therapy, and missed the therapy and group members more than the BPD group. CONCLUSION: After the lockdown, BPD patients received a closer follow-up than AvPD patients, and the latter reported more negative feelings related to change in their treatment situation.

Inter-Rater Reliability of the Structured Interview of DSM-IV Personality (SIDP-IV) in an Adolescent Outpatient Population.

Personality disorders (PDs) are a class of mental disorders which are associated with subjective distress, decreased quality of life and broad functional impairment. The presence of one or several PDs may also complicate the course and treatment of symptom disorders such as anxiety and depression. Accurate and reliable means of diagnosing personality disorders are thus crucial to ensuring efficient treatment planning and resource allocation, a fact which is widely acknowledged within the adult mental health field. In adolescents, on the other hand, the consensus view has been that the rapid and discontinuous processes of normal personality development render the construct of PD in adolescents clinically unhelpful and conceptually dubious. However, recent research has established the reliability and validity of the construct, heralding an increased interest in the field, with important conceptual and clinical implications. The present article presents reliability data for the Structured Interview of DSM-IV Personality (SIDP-IV) in an adolescent outpatient population. For this study, 25 interviews conducted by experienced clinicians were blindly re-scored based on sound recordings, which allowed for the calculation of intra-class correlation metrics. The intra-class correlation coefficient for categorical diagnosis of specific personality disorders was found to be 0.876 (95% CI 0.718-0.945); Cohen's kappa for presence/absence of personality diagnosis was found to be 0.896. The present study found excellent intra-rater reliability for the sample, which suggests that the SIDP-IV is a suitable instrument for assessing personality pathology in adolescent populations.

Vulnerability of personality disorder during the Covid-19 crises - a multicenter survey of treatment experiences among patients referred to treatment.

BACKGROUND: The societal shutdown due to the Covid-19 pandemic involved mental health services for personality disorder (PD) and was introduced from 12 March 2020 in Norway. Rapid implementation of treatment modifications was required for patients typically characterized by insecure attachment and vulnerability to separation. AIM: To investigate immediate reactions to the shutdown of services; alternative treatment received; and differences related to age in a clinical sample of patients with PD. DESIGN: A survey performed from June to October 2020 (after the first Covid-19 wave) among 1120 patients from 12 units offering comprehensive group-based PD programs. RESULTS: The response-rate was 12% (N = 133). Negative feelings of anxiety, sadness, and helplessness were noteworthy immediate reactions, but the dominating attitude was accommodation. Younger patients (<26 years) reported more skepticism and less relief. Modified treatment was mainly telephone therapy. Digital therapy was less available, but was more frequent among younger patients. A minority received digital group therapy. Most patients rated the frequency and quality of modified treatments as satisfactory in the given situation, but also worried about own treatment progress, lack of group therapy, and 47% missed seeing the therapist when having telephone consultations. CONCLUSION: The survey confirms a radical modification from comprehensive group-based PD programs to telephone consultations, low availability of digital consultations and group treatments. Taking a short-term, first wave perspective, the survey indicates a noteworthy capacity among poorly functioning patients for accommodating to a clearly challenging situation, as well as considerable concern about treatment progress.

Vulnerability of personality disorder during COVID-19 crises: a multicenter survey of mental and social distress among patients referred to treatment.

BACKGROUND: Relational and emotional problems, dysregulation, self-harming or substance abuse often characterize personality disorders (PD). In Norway, COVID-19 restrictions led to an abrupt shutdown of services from 12 March 2020 also including specialized PD treatments. AIMS: The objective of this study was to investigate social and mental distress among patients with PDs during the first COVID-19 wave. DESIGN: A survey was distributed after the first COVID-19 wave (June-October 2020) among 1120 patients from 12 PD treatment units. RESULTS: The response rate was 12% (N = 133). The survey reflected impairment of occupational activity (53% <50% activity last 6 months), life quality (EQ-5D-VAS: 56, SD 19), and personality functioning (LPFS-BF ≥12: 81%, 35% avoidant PD, 44% borderline PD) and high levels of depression and anxiety (PHQ-9 ≥ 10: 84%, GAD-7 ≥ 10: 68%), 49% with health-related anxiety. Problem increase was reported for anxiety (28%), depression (24%), aggression (23%), substance use (14%), and 70% of parents had more child-care difficulties. Self-destructive behaviors (26%) did not increase. The majority (78%) reported increased or unchanged social isolation and loneliness. Occupational activity declined with negative effects on part-time jobs/rehabilitation. Therapist contact was mainly telephone-based (63% ≥ weekly contact). More severe personality problems, current depressive symptoms, and self-harming before 12 March were associated with more frequent consultations. CONCLUSION: The survey confirms severe, enhanced levels of mental distress among patients receiving telephone-based consultations as the main alternative to specialized PD treatment during the COVID-19 shutdown. The most vulnerable patients received more frequent consultations and self-destructive actions did not increase.

The Punished Self, the Unknown Self, and the Harmed Self - Toward a More Nuanced Understanding of Self-Harm Among Adolescent Girls.

Self-harm among adolescents, mostly girls, has increased in the last years. Self-harm is associated with mental illness and the risk of suicide. This qualitative study aims to explore the lived experience of self-harm as it is related to everyday life and challenges among adolescents. Nineteen girls (13-18 years of age) in a clinical population (strategic selection) participated in personal interviews analyzed by Interpretative Phenomenological Analysis to capture how they made meaning of self-harm and essential features of experiencing self-harm. Adult persons with the first-hand experience of self-harm were included in the research analysis. Data-analysis resulted in three superordinate themes which all speak about ways to handle inner pain and vulnerability: 1. "I deserve pain," 2. "I don't want to feel anything," and 3. "I'm harmed, and no one cares." Each superordinate theme included four main themes characterizing essential features of difficult experiences during self-harm, the purpose of the action, self-descriptions, and the role of others during self-harm. The three superordinate themes are discussed as emerging self-representations - "the punished self," "the unknown self," and "the harmed self" - during the transitional age of adolescence. This article argues that subjective personal data on self-harm related to adolescents' everyday lives may indicate diversity in the capacity to integrate difficult needs, feelings, and traumatic experiences as part of the self. This knowledge may bring a nuanced understanding of self-harm in adolescence, enhance self-understanding and treatment motivation, and inform clinical adjustment.
