Affective temperaments and self-harm in adolescents: a cross-sectional study from a community sample

Weekly links among irritability and suicidal thoughts and behaviors in high-risk youth

BACKGROUND

Previous studies demonstrate a link between irritability and suicidal thoughts and behaviors (STBs) in youth samples. However, they have mostly assessed irritability in community samples and as a largely dispositional (i.e. trait-like) construct. Thus, it remains unclear to what extent links between irritability and STBs reflect within-person processes of elevated risk in clinically meaningful time periods.

METHODS

The present study used clinical data from 689 adolescents aged 12-19 years attending a total of 6,128 visits at a specialty Intensive Outpatient Program for depressed and suicidal youth to examine patterns in weekly assessments of irritability and STBs throughout treatment, including associations among trends and fluctuations departing from these trends via multilevel structural equation modeling. Youth completed self-report measures of irritability, depression, and STBs weekly as part of standard IOP clinical care.

RESULTS

Overall, two-thirds of variance in weekly irritable mood was accounted for by between-person differences and the remaining portion by weekly fluctuations. After controlling for depression, during weeks when youth were more irritable they experienced increased STBs. Rates of change in irritability and STBs tended to track together at early stages of treatment, but these effects were generally accounted for by depression severity.

CONCLUSIONS

Our results suggest that although changes in STBs are best accounted for by depression, irritability can be understood as a specific, proximal risk factor for youth STBs that exacerbates youth STBs in clinically informative timeframes above and beyond depression.

The Impact of Affective Temperaments on Suicidal Ideation and Behaviors: Results from an Observational Multicentric Study on Patients with Mood Disorders

Suicide ideation and behaviors are major health issues in the field of mental health. Several psychological and psychosocial factors have been taken into account as possible predictors of suicidality. Only recently affective temperaments have been considered as possible factors linked to suicide. This study aims to investigate the relationship between affective temperaments and suicidality, including the lifetime onset of suicide ideation, lifetime presence of suicide attempts and the total number of lifetime suicide attempts. This is a naturalistic multicentric observational study, involving outpatient units of seven University sites in Italy. Patients were administered with the short version of TEMPS-M and the Columbia Suicide Severity Rating Scale. A total of 653 participants were recruited, with a diagnosis of bipolar (55.7%), unipolar (35.8%) and cyclothymic disorder (8.4%). Regression models showed that the presence of lifetime suicide behaviors was increased in patients presenting trait related impulsivity (p < 0.0001), poor free-interval functioning (p < 0.05), higher number of affective episodes (p < 0.01), higher number of hospitalizations (p < 0.0001), cyclothymic and irritable affective temperaments (p < 0.05 and p < 0.05, respectively). Conversely, the presence of hyperthymic affective disposition reduced the likelihood of having suicidal behaviors (p < 0.01). Lifetime suicidal ideation was associated with trait-related impulsivity (p < 0.001), poor free-interval functioning (p < 0.05), higher number of affective episodes (p < 0.001) and of hospitalizations (p < 0.001). Depressive temperaments increased the likelihood of presenting suicidal ideation (p < 0.05), along with irritable temperaments (p < 0.01), contrary to hyperthymic affective (p < 0.05). Results of the present study confirm that affective disposition has a significant impact on the onset of suicidal ideation and behaviors, and that affective dispositions should be assessed in clinical settings to identify people at risk of suicide. Moreover, a wider clinical evaluation, including different clinical psychopathological dimensions, should be taken into consideration to develop effective preventive interventions.

Relationship Between Affective Temperaments and Suicide Risk in Patients With First-Onset Major Depressive Disorder

Background

People may endorse suicidal behavior during a major depressive episode. Affective temperaments may play a role in this risk. We explored the relationship between affective temperaments and suicide and identified some traits that can predict suicide risk in depression.

Materials and Methods

We analyzed the results of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A) in 284 participants recruited from a psychiatric clinic and the community in Beijing and compared the subscale scores (temperaments of cyclothymic, dysthymic, anxious, irritable, and hyperthymic) among major depressive disorders (MDDs) vs. the general population as well as depressive patients with vs. without suicide risk, using Student's test, chi-square test, rank-sum test, and multivariable regression modeling.

Results

The incidence of suicidal risk in depressive subjects was 47.62% (80/168). Being unmarried (p < 0.001), unemployed (p = 0.007), and temperaments of dysthymic, cyclothymic, anxious, and irritable scores (all p < 0.001) were significantly more prevalent in patients with depression than in the general population. Young age (p < 0.001), female sex (p = 0.037), unmarried (p = 0.001), more severe depression (p < 0.001), and dysthymic, anxious, and cyclothymic temperament (all p < 0.05) were significantly more prevalent in patients with depressive disorder than those without suicide risk. The logistic regression analysis showed that younger age (odds ratio [OR] = 0.937, 95% CI 0.905∼0.970), female sex (OR = 2.606, 95% CI 1.142∼5.948), more severe depression (OR = 1.145, 95% CI 1.063∼1.234), cyclothymic temperament (OR = 1.275, 95% CI 1.102∼1.475), and dysthymic temperament (OR = 1.265, 95% CI 1.037∼1.542) were all independently associated with high suicidal risk in patients with first-onset major depression (p < 0.05).

Conclusion

Temperament traits differ between the general population and people suffering from MDD. Subjects with MDD who have much more severe depressive symptoms and a cyclothymic or dysthymic temperament were at a high risk of suicide.

The assessment of cyclothymic-hypersensitive temperament in youth with mood disorders and attention deficit hyperactivity disorder

BACKGROUND

Cyclothymic-hypersensitive temperament (CHT) has been related to both depression and bipolarity, as well as to suicidality. Recently, a psychometrically sound way of assessment has been validated in youth (Cyclothymic-Hypersensitive Temperament Questionnaire, CHTQ), but data on clinical populations are still scant. Aim of our study is to further explore the structure and other psychometric properties of the revised version of CHTQ and its clinical implications in clinical samples.

METHODS

The study is based on a dataset of patients with unipolar depression, bipolar disorder and attention deficit and hyperactivity disorder (ADHD) (243 patients, 135 males, mean age 14.22 ± 2.16 years, age range 9-18 years), compared to a community sample of adolescents (398 subjects, 95 boys, mean age 15.47 ± 1.96 years, age range 10-18 years) RESULTS: The two-correlated factor structure of CHT has been confirmed, with a moodiness/hypersensitiveness factor, correlated with internalizing symptoms, and an impulsiveness/emotional dysregulation factor, correlated with externalizing symptoms. All CHTQ scores correlate with global functioning. CHTQ total scores discriminate patients from healthy controls. Only CHTQ impulsiveness/emotional dysregulation subscale score is higher in bipolar patients, compared to unipolar depression and ADHD, whereas neither CHTQ moodiness/hypersensitiveness subscale score nor CHTQ total score discriminate between clinical groups.

LIMITATION

Data on current mood states are unavailable. Patients were recruited in a third level clinic. The unipolar depression group is relatively small.

CONCLUSION

CHT may be a rapid and reliable screening and diagnostic tool in the clinical practice with youth, exploring the cyclothymic dimension in different psychiatric disorders.

Cyclothymic-hypersensitive temperament in youths: Refining the structure, the way of assessment and the clinical significance in the youth population

BACKGROUND

Although a better understanding of the prodromes of affective disorders in youth has important clinical and research implications, empirical data are still unconclusive. Cyclothymic-hypersensitive temperament (CHT) has been linked to both depression and bipolarity, as well as to suicidality. Its conceptualization is still debated, as well as a comprehensive, psychometrically sound way of assessment.

METHODS

factor structure, reliability, measurement invariance, convergent and divergent validity of the previously published CHT questionnaire (a youth version derived from Temperament Evaluation in Memphis Pisa and San Diego (TEMPS) was assessed in a school-based sample of 2959 students aged from 10 to 14 years (mean age = 11.8 ± 0.97 years). Furthermore, accuracy, sensitivity and specificity were calculated for a new cut-off score related to the presence of general psychopathology symptoms.

RESULTS

CHT is better conceptualized in a two-correlated factors model, a moodiness/hypersensitiveness factor, more associated with internalizing symptoms, and an impulsiveness/emotional dysregulation factor, more associated with externalizing symptoms. The revised 22-items version of the CHT questionnaire with a cut-off score of 15 for females and 17 for males results accurate, sensitive and specific enough for the recognition of cyclothymic adolescents with clinical symptoms.

LIMITATION

the cross sectional design and the self-report nature of the measures limit the findings.

DISCUSSION

Cyclothymic-hypersensitive temperament is a relevant concept in the realm of affective disorder and can be reliably assessed in youths. It may describe youths with the coexistence of both internalizing and externalizing symptoms that can be difficult to diagnose with a DSM perspective.

Suicidal Risk and Affective Temperaments, Evaluated with the TEMPS-A Scale: A Systematic Review

BACKGROUND

Among risk factors for suicidal behavior, there is growing interest in associations with stable affective temperament types, particularly based on assessment with the TEMPS-A self-rating scale.

AIM

As research on this topic has not been reviewed systematically, we synthesized relevant, reported research findings.

METHODS

Systematic searching identified peer-reviewed reports pertaining to associations of suicidal behavior or ideation with affective temperament types evaluated with TEMPS-A. We summarized available findings and applied quantitative meta-analytic methods to compare scale scores in suicidal versus nonsuicidal subjects.

RESULTS

In 21 of 23 TEMPS-A studies meeting inclusion criteria, anxious, cyclothymic, depressive, or irritable temperament scores were significantly higher with previous or recent suicide attempts or ideation in both psychiatric and general population samples compared to nonsuicidal controls, whereas hyperthymic temperament scores were lower in 9 of 11 reports. These findings were synthesized by random-effects meta-analyses of standardized mean differences in TEMPS-A temperament scores in suicidal versus nonsuicidal subjects. Associations ranked: depressive ≥ irritable > cyclothymic > anxious > hyperthymic (negative).

CONCLUSIONS

Affective temperaments, especially depressive and irritable, were strongly associated with suicidal risk, whereas hyperthymic temperament appeared to be protective.

Association between irritability and suicide-related outcomes across the life-course. Systematic review of both community and clinical studies

BACKGROUND

Irritability is gaining considerable attention as a risk factor for suicide-related outcomes (suicide mortality, attempt, and ideation). However, the evidence of this association is scant. We conducted a systematic review of the evidence regarding the associations between irritability and suicide-related outcomes across the life-course.

METHODS

We conducted a systematic search on Medline and PsycINFO (up to January 2018) for original articles published in English investigating the association between irritability and suicide-related outcomes. Two researchers independently screened the articles, assessed the quality of the evidence (New-Castle-Ottawa Scale) and extracted study characteristics.

RESULTS

Thirty-nine studies were retrieved, most were of low/medium quality. Twelve assessed irritability in childhood/adolescence (6 in community samples, 6 in clinical samples) and 27 in adulthood (7 in community samples, 20 in clinical samples). In both childhood/adolescence and adult samples, most community-based studies reported a positive association between irritability and suicidal ideation and/or attempt, while clinical studies reported mixed findings. More specifically, in clinical studies, the association of irritability with suicide-related outcomes (i) was not supported among adult depressed patients, (ii) findings were inconsistent in adult bipolar patients, (iii) for inpatients/outpatients with various psychiatric disorders/conditions, association was observed in adulthood but not in childhood/adolescence.

LIMITATIONS

Differences in methodology and definition/measurement of irritability limited the comparability of included studies.

CONCLUSIONS

Although irritability has been proposed as a promising transdiagnostic factor associated with suicide-related outcomes, the absence of consensus in the definition of irritability (vs anger or reactive/impulsive aggression), the poor methodological quality, and the lack of developmental considerations mitigate the conclusions.

Non suicidal self-injury in referred adolescents with mood disorders and its association with cyclothymic-hypersensitive temperament

BACKGROUND

Non suicidal self-injuries (NSSIs) are deliberate self-harm behaviors without suicidal intent, usually starting in adolescence, with increasing rates of occurrence both in epidemiological and clinical samples. Several studies associated cyclothymic-hypersensitive temperament (CHT) with self-harm behaviors and suicidal risk. Aim of this study is to explore the association between NSSIs and CHT in a clinical sample of adolescents. We hypothesized that CHT may differentiate NSSI from non-NSSI adolescents with mood disorders, when other psychopathological features are controlled for.

METHODS

A consecutive sample of 89 adolescents with mood disorders were assessed for presence and phenomenology of NSSIs, CHT, demographics, comorbid categorical psychiatric diagnoses, dimensional psychopathology, impairment and previous suicide attempts.

RESULTS

NSSIs were reported in 52% of the sample, with higher rates in females and in bipolar disorder. Regression analyses showed that CHT, but not age, gender, bipolar vs depression diagnosis, functional impairment, was associated with NSSIs.

DISCUSSION

CHT may be in close association with NSSIs in adolescents with mood disorders. An assessment of CHT in adolescents referred for mood disorder may help to detect specific psychological features of NSSIs, which may improve diagnostic and treatment strategies.

LIMITATIONS

Given the cross-sectional design, a developmental relation between CHT and NSSIs cannot be determined. The small sample size and the selection bias of severely impaired patients limit the generalization of the results. More sophisticated measures of CHT may consent to explore other dimensions of the cyclothymic construct (i.e., emotional intensity, emotional reactivity, emotional stability, positive vs. negative emotions, interpersonal sensitivity, impulsivity).

Association between suicide-related ideations and affective temperaments in the Japanese general adult population

BACKGROUND

Suicide rates are vastly higher in Japan than in many other countries, although the associations between affective temperaments and suicide-related ideations in the general adult population remain unclear. Therefore, we aimed to elucidate these associations in the present study.

METHODS

We analyzed data from 638 Japanese volunteers who completed both the Patient Health Questionnaire (PHQ-9) and the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A). Participants were then divided into three groups based on PHQ-9 summary scores and responses to the suicide-related ideation item: non-depressive control group (NC; N = 469), depressive symptoms without suicide-related ideations group (non-SI; N = 135), and depressive symptoms with suicide-related ideations group (SI; N = 34). The depressive symptoms were defined for PHQ-9 summary scores ≥5, and the suicide-related ideations were defined for PHQ-9 #9 score ≥1. We then compared TEMPS-A scores among the groups using Kruskal-Wallis tests. Then the 95% confidence intervals of differences in TEMPS-A subscale scores between the NC and non-SI groups, or between NC and SI groups, were calculated.

RESULTS

Participants of the SI group exhibited significantly higher scores on the depressive, irritable, and anxious temperament subscales than those of the non-SI group. Similarly, women of the SI group exhibited significantly higher scores of the depressive and irritable temperament subscales than women of the non-SI group, while men of the SI group exhibited significantly higher depressive temperament scores than those of the non-SI group. Among all participants and only men, cyclothymic subscale scores were higher in those of the SI group than the non-SI group (not significant), although the 95% confidence intervals did not overlap.

LIMITATIONS

The cross-sectional study design was the main limitation.

CONCLUSIONS

Depressive, irritable, and anxious temperaments are significant risk factors for suicide-related ideations in the Japanese general adult population. Furthermore, irritable temperament in women and depressive temperament in men are associated with suicide-related ideations.

Affective temperaments, as measured by TEMPS-A, among self-poisoning nonlethal suicide attempters

Suicidal behaviors are serious public health problems. The prominent association of mood disorders with suicide, along with the renaissance of the spectrum concept of psychiatric disorders in the recent decades, prioritizes the investigation of temperament variants in suicidal individuals. This study aimed to explore the relationship between affective temperaments and nonviolent suicide attempts. We administered Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto questionnaire (TEMPS-A) to 141 (27 males and 114 females) consecutive self-poisoning non-lethal suicide attempters at a Medical Toxicology Center and a sex and age matched group of healthy individuals (28 males, 112 females). Female suicide attempters scored significantly higher in depressive, cyclothymic, irritable, and anxious temperaments compared with female controls, whereas male cases' scores were significantly higher in depressive and anxious subscales compared with control males. Except for hyperthymic temperament which did not reveal any significant effects, depressive (OR: 11.5), cyclothymic (OR: 3.8), irritable (OR: 2.3), and anxious (OR: 8.8) temperaments were predictors for nonviolent suicide attempts. Therefore, this study replicated the evidence for the strong association of depressive temperament with suicide attempts. The hyperthymic temperament appeared to have neither protective nor predisposing influence. Further studies are needed to identify the role of this independent temperament.

Affective temperaments and suicidal ideation and behavior in mood and anxiety disorder patients

BACKGROUND

Clinical characteristics proposed to be associated with suicidal risk include affective temperament types. We tested this proposal with two methods in a large sample of subjects with mood and anxiety disorders.

METHODS

We assessed consecutive, consenting subjects clinically for affective temperament types and by TEMPS-A self-ratings for associations of temperament with suicidal ideation and acts, using standard bivariate methods, and multivariate logistic regression models.

RESULTS

Among 2561 subjects (major depressive, 1171; bipolar, 919, anxiety disorders, 471), temperament-types and TEMPS-A (39-item Italian version) subscale scores differed by risk of suicidal acts or ideation. Suicidal acts and ideation were most associated with cyclothymic and dysthymic, and less with hyperthymic temperaments. These associations were sustained by multivariate modeling that included diagnosis, age, sex, and diagnosis.

LIMITATIONS

Not all subjects completed TEMPS-A self-ratings; clinical assessments of temperaments were not standardized, and long-term stability of temperament assessments was not tested.

CONCLUSIONS

The findings support and extend associations of cyclothymic-dysthymic temperaments with suicidal acts and ideation, whereas hyperthymic temperament may be protective.

Temperaments in completed suicides: Are they different from those in suicide attempters and controls?

BACKGROUND

Temperaments in completed suicides have never been assessed whereas there is substantial research on temperaments in attempted suicides and psychiatric patients.

METHODS

The significant others of 18 completed suicides participated in this study in order to provide an assessment of temperaments, hopelessness, depression and the suicide risk of their loved ones. The data were compared with data from 244 psychiatric patients of whom 83 had attempted suicide in the previous month. The following instruments were used: the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A), the Beck Hopelessness Scale (BHS), the Gotland Scale for Male Depression (GSMD), and the Mini International Neuropsychiatric Interview (MINI) module for assessing suicide risk.

RESULTS

Individuals who died by suicide more frequently had scores of 9 or higher on the BHS and higher MINI suicide risk scores compared with patients with mood disorders who had not attempted suicide in the previous month. Completed suicides also had lower scores on the TEMPS-A Cyclothymia and Anxiety scales and on the MINI suicide risk scale than mood disorder patients with a recent suicide attempt.

LIMITATIONS

Proxy assessment of variables through survivors can result in underestimation of psychiatric morbidity and other parameters investigated, and limits the generalization of our results

CONCLUSIONS

Our study adds information about temperamental subtypes and other variables in completed suicides and points to their difference from attempted suicides and non-suicidal psychiatric patients.

Temperament and suicide: A national study

BACKGROUND

Several studies have shown temperament variants in suicidality. Yet, to our knowledge, the association between temperaments and suicide attempts has not been studied on a nationally representative level nor systematically in subjects with no mental disorders. Also, although hyperthymic temperament is recognized as protective of most mental disorders, its role in the protection from self-harm remains inconclusive.

METHODS

The study is based on nationally representative data of all Lebanese adults. Mental disorders were assessed using the Composite International Diagnostic Interview, whereas the five affective temperaments were assessed using the TEMPS-A.

RESULTS

Anxious temperament is a solid and strong risk factor for suicide attempts in subjects with (OR: 10.1) and without (OR: 9.0) mental disorders. Depressive (OR: 4.3) and irritable (OR: 5.1) temperaments are risk factors for suicide attempt among subjects with mental disorders. Hyperthymic temperament plays a dual role in females with mental disorders: while the hyperthymic trait "having self-confidence" is strongly protective of suicide attempts, "liking to be the boss", "getting into heated arguments", and "the right and privilege to do as I please" are hyperthymic risk traits for suicide attempts reflecting the "dark side" of the hyperthymic temperament. Interestingly, these three hyperthymic risk traits--in the absence of "having self-confidence"--are a universal risk for suicide attempt in females with mental disorder.

LIMITATIONS

Social desirability could have led to the under-reporting of suicide attempts and mental disorders.

CONCLUSIONS

The anxious temperament plays a strong role in predicting suicide attempts in the community, in the presence and absence of diagnosable mental disorders. The irritable and the depressive temperaments are additional risks in subjects with mental disorders. The dual role of the hyperthymic temperament is quite interesting: while it is protective of suicidal behavior, it also has a dark side in subjects with mental disorders.

Digital comparison of healthy young adults and borderline patients engaged in non-suicidal self-injury

BACKGROUND

It still remains unclear whether non-suicidal self-injury (NSSI) in young adult populations represents an actual symptom leading to psychiatric illness, constitutes a disorder itself or is rather a cultural peer influence. The purpose of this web-based qualitative cross-sectional study was to characterize NSSI (type of injury, frequency, tools, body parts, circumstances) in 50 patients with borderline personality disorder (NSSI + BPD) in direct comparison with 50 age and gender matched non-clinical young adults (NSSI - BPD), all of them currently or previously engaged in NSSI.

METHODS

Self-harming participants completed an open-access, anonymous 75-items questionnaire including the temperament questionnaire briefTEMPS-M.

RESULTS

The mean age of NSSI onset was 20.56 ± 6.36 (NSSI + BPD) and 17.5 ± 9.28 years (NSSI - BPD), respectively (p = 0.261). NSSI - BPD participants (1) rarely sought out medical treatment (p < 0.001) and differed significantly from BPD patients; They (2) reported more often fear and disappointment as feelings preceding their self-harm (p < 0.001 each); (3) cut themselves in more locations (p = 0.005) and (4) in rather hidden areas (lower limb, proximal) (p = 0.002); (5) had lower depressive temperament scores (p = 0.007); and (6) scored generally fewer character traits "at risk" (p = 0.043) with a lower total score (p = 0.018). NSSI tended to onset slightly earlier in life and in different shape when BPD was absent.

CONCLUSIONS

Our findings support current approaches of early NSSI recognition and identification of risk profiles. Further prospective studies, which have to be sufficiently large and longitudinal, are needed and of great importance.
