Clinical Characteristics Associated with Suicidal Attempt and Non-Suicidal Self-Injury in Korean Adolescents

ObjectiveThis study evaluated the association between mood and anxiety symptoms and suicidal attempt (SA) and/or non-suicidal self-injury (NSSI) in adolescents seeking mental health services. We also tested predictors of SA and NSSI. MethodsWe retrospectively reviewed the medical records of 220 adolescents who completed psychological assessment in clinical sample. Participants did the Adolescent General Behavior Inventory (A-GBI) and Children’s Depression Inventory (CDI). SA and NSSI were assessed retrospectively by interview. The caregiver of participants completed the Beck Depression Inventory (BDI) for themselves. Results17% of total participants had a history of SA, and 24% experienced NSSI. Both SA and NSSI were more common in girls. The score of depressive subscale on A-GBI was higher in adolescents with SA than those without. The participants with NSSI showed higher scores on CDI and depressive subscale on A-GBI than those without. SA was associated with maternal BDI and history of NSSI; female sex, depressive subscale on A-GBI, and history of SA with NSSI. ConclusionOur study found that NSSI and SA are strongly associated in adolescents. Female sex and depressive symptoms of the adolescents were also significantly associated with NSSI in Korean adolescent. Findings are consistent with patterns in other countries.     

Depression as a mediator between frequent nightmares and non-suicidal self-injury among adolescents: a 3-wave longitudinal model

BackgroundFrequent nightmares and depression are associated with non-suicidal self-injury (NSSI) in adolescents. Little is known about the mediating role of depression in the nightmare-NSSI link. This study explores the longitudinal mediating effect of depression on the relationship between frequent nightmares and NSSI as well as the moderating effect of gender using a three-wave longitudinal design.MethodsParticipants were adolescents from the Shandong Adolescent Behavior and Health Cohort who were surveyed at baseline, 1 year later, and 2 years later. A self-administered questionnaire was used to measure nightmare frequency, depression, and NSSI. Structural equation modeling and multiple-group analysis were used to test the mediating effect of depression and the moderating effect of gender. Covariates included demographics and earlier measures of depression and NSSI.ResultsAmong 6995 participants, 3399 (48.6%) were females, mean age was 14.86 (SD = 1.50) years at baseline. Frequent nightmares had a significant mediation effect on NSSI through depression (B_ab = 0.06, 95% CI = 0.02–0.10) after controlling for demographics and earlier measures of depression and NSSI. Gender had no significant moderating effect on the nightmare-NSSI association.LimitationsAll data were collected by self-report.ConclusionsThe association between frequent nightmares and NSSI in adolescents was partially mediated by depression. Frequent nightmares and depression should be assessed and treated to prevent self-harm in adolescents.     

The influence of personality traits and emotional and behavioral problems on repetitive nonsuicidal self-injury in a school sample

BackgroundNonsuicidal self-injury (NSSI) is highly prevalent among adolescents and associated with various mental health problems and suicidality. Previous studies have found that certain personality traits are related to NSSI behavior, however only few studies examined personality traits in adolescents with NSSI. Our study aimed to assess the relationship between personality traits and emotional and behavioral problems in predicting repetitive NSSI among adolescents from a school sample.MethodsFour hundred and forty-seven students (M = 14.95 years, SD = 0.74, 52% male) completed self-report measures on NSSI, personality traits, and emotional and behavioral problems.ResultsThe past year prevalence of occasional and repetitive NSSI was 4.9% and 6.3% respectively. Repetitive NSSI was significantly associated with female gender, higher levels of age, novelty seeking, harm avoidance, self-transcendence, antisocial behavior, and positive self and lower levels of persistence and self-directedness in univariate analyses. However, multivariate logistic regression analyses indicated that only high levels of antisocial behavior and low levels of self-directedness significantly predicted repetitive NSSI.ConclusionsThe association between a lack of self-directedness and NSSI emphasizes the significance of targeting self-directedness in psychotherapy by strengthening self-awareness, affect tolerance and emotion regulation, as well as establishing and pursuing long-term goals.     

Differences in psychological symptoms and self-competencies in non-suicidal self-injurious Flemish adolescents

The aim of the present study was to examine differences in psychological symptoms and sense of self-competence between adolescents with and without non-suicidal self-injurious behavior. We collected data in a sample of 281 Flemish adolescents. Psychological symptoms and self-competencies were assessed by means of the Youth Self-Report (YSR) and NSSI was assessed using the Self-Harm Inventory (SHI-22). Results showed significant differences between adolescents with and without NSSI on all psychopathological subscales. Furthermore, adolescents engaging in NSSI reported significantly lower scores on social competence, but equal levels on other competencies. Results revealed that externalizing problems and attention/thought/social problems are significantly associated with NSSI. Results also showed that having a higher score on aggressive behavior or thought problems increases the chance of belonging to the NSSI group; whereas a higher score on the social competence scale decreases the chance of belonging to the NSSI group. Clinical implications of these findings are discussed.     

The relationship between the biogenetic temperament and character and psychopathology in adolescents

BACKGROUND: This study was conducted to investigate the relationship between patterns of temperament and character and self-reported psychopathology in adolescents from the community. SAMPLING AND METHODS: The Junior Temperament and Character Inventory (JTCI) and Youth Self-Report (YSR) instruments were administered to 623 Korean middle school students (boys/girls = 331/292; age = 13.3 +/- 0.9 years old). Multiple linear regression analyses were used to evaluate the relationship between temperament and character based on Cloninger's biogenetic theory of personality and youth psychopathology of internalizing and externalizing problems. RESULTS: Internalizing problems of the YSR (withdrawn, somatic complaint and anxious/depressed scales) were significantly related to high Harm Avoidance and low Reward Dependence (JTCI temperament) and low Self-Directedness and high Self-Transcendence (JTCI character). Externalizing problems of the YSR (delinquency and aggression) were significantly associated with high Novelty Seeking and high Harm Avoidance (JTCI temperament) and low Self-Directedness, low Cooperativeness and high Self-Transcendence (JTCI character). CONCLUSIONS: Findings of the current study suggest that specific patterns of temperament and character potentially influence adolescents' psychopathology in the community.     

Non-suicidal self-injury in adolescence: A longitudinal study of the relationship between NSSI,psychological distress and perceived parenting

ObjectiveThe present study investigates whether either adolescents' psychological distress and/or perceived parenting predicted the occurrence of NSSI. Furthermore, the consequences of NSSI are examined in a three-wave longitudinal study.DesignThe sample at time 1 (age 12) consisted of 1396 adolescent reports and 1438 parent reports. At time 2 (age 13), 827 adolescent reports and 936 parent reports were obtained. Time 3 (age 14) included 754 adolescent reports and 790 parent reports. Psychological distress of adolescents was measured using the Strengths and Difficulties Questionnaire. Perceived parenting behaviors were examined by the Parental Behavior Scale and the Psychological Control Scale.ResultsA total of 10% of the adolescents engaged in NSSI at least once before age 15. Higher psychological distress of adolescents at time 1 was associated with the presence of NSSI at time 2 or 3. The association between psychological distress at time 1 and perception of decreased parental rule setting at time 3 was mediated by the presence of NSSI at time 2.ConclusionsThe present study showed that psychological distress at age 12 predicts NSSI over time and that parental awareness of NSSI changes the perception of parenting behaviors.     

Adolescent Anorexia Nervosa: Cognitive performance after weight recovery

Objective

Although there is no definitive consensus on the impairment of neuropsychological functions, most studies of adults with Anorexia Nervosa (AN) find impaired functioning in cognitive domains such as visual–spatial abilities. The objective of this study is to assess the cognitive functions in adolescents with AN before and after weight recovery and to explore the relationship between cognitive performance and menstruation.

Methods

Twenty-five female adolescents with AN were assessed by a neuropsychological battery while underweight and then following six months of treatment and weight recovery. Twenty-six healthy female subjects of a similar age were also evaluated at both time points.

Results

Underweight patients with AN showed worse cognitive performance than control subjects in immediate recall, organization and time taken to copy the Rey's Complex Figure Test (RCFT). After weight recovery, AN patients presented significant improvements in all tests, and differences between patients and controls disappeared. Patients with AN and persistence of amenorrhea at follow-up (n = 8) performed worse on Block Design, delayed recall of Visual Reproduction and Stroop Test than patients with resumed menstruation (n = 14) and the control group, though the two AN groups were similar in body mass index, age and psychopathological scale scores.

Conclusion

Weight recovery improves cognitive functioning in adolescents with AN. The normalization of neuropsychological performance is better in patients who have recovered at least one menstrual cycle. The normalization of hormonal function seems to be essential for the normalization of cognitive performance, even in adolescents with a very short recovery time.     

Age of onset of non-suicidal self-injury in Dutch-speaking adolescents and emerging adults: An event history analysis of pooled data

ObjectiveNon-Suicidal Self-Injury (NSSI) has emerged as an important mental-health concern. However, epidemiological features like age of onset of NSSI have remained understudied. Therefore, the current study investigated the distribution of age of onset of NSSI in pooled sample of Dutch-speaking adolescents and emerging adults using event history analysis.MethodEleven datasets measuring age at first NSSI in community and clinical participants collected by researchers in the Dutch-speaking part of Belgium were pooled together. The final dataset consisted of 1973 community males, 1901 community females, and 505 clinical females. Discrete-time event history analysis was used to model the effect of gender and psychiatric disorders on the age of onset of NSSI.ResultsTwenty-one percent of adolescents from the community samples engaged in at least one episode of NSSI by the age of 25 years. Irrespective of the type of sample (community or psychiatric disorder), the probability of age of onset peaked around the age of 14–15 years. A second peak was observed around the age of 20 and 24 years in the community and psychiatric samples respectively.ConclusionsPsychosocial interventions for prevention of NSSI should not only target adolescence through school mental health programs but also target emerging adults at the university level.     

Self-reports on mental health problems of youth with moderate to borderline intellectual disabilities

OBJECTIVE: To determine the extent to which the Youth Self-Report (YSR) can be used to assess emotional and behavioral problems in adolescents with intellectual disabilities (IDs). METHOD: In 2003, 281 11- to 18-year-olds with IDs (IQ > or =48) completed the YSR in an interview, and in 1993, 1,047 non-ID adolescents completed the YSR themselves. Parents completed the Child Behavior Checklist (CBCL). The ID sample was split into lower (IQ 48-69) and higher (IQ > or =70) IQ groups. Cronbach's alpha values of the YSR scales and (intraclass) correlation coefficients between and within YSR and CBCL scale scores were calculated to determine parent-adolescent agreement and YSR construct validity, which were compared between samples. Mean YSR scale scores were compared between adolescents with ID with and without psychiatric symptoms. RESULTS: Cronbach's alpha, parent-adolescent agreement, and indications of construct validity were about similar in all samples, although discriminant validity was somewhat weaker in the lower IQ group. Mean scale scores were 1.5 to 2.0 times higher for ID adolescents with psychiatric symptoms. CONCLUSIONS: The YSR seems applicable in youth with an IQ > or =48. Further research is needed to refine and confirm these findings and the factor structure of the YSR in adolescents with ID and to differentiate between adolescents with moderate and mild IDs.     

Temperament and character in women with anorexia nervosa

The present study examined temperament differences among anorexia nervosa (AN) subtypes and community controls, as well as the effect of body weight on personality traits in women with AN. Temperament and Character Inventory (TCI) scores were compared between 146 women with restrictor-type AN (RAN), 117 women with purging-type AN (PAN), 60 women with binge/purge-type AN (BAN), and 827 community control women (CW) obtained from an archival normative database. Women with AN scored significantly higher on harm avoidance and significantly lower on cooperativeness than CW. Subtype analyses revealed that women with RAN and PAN reported the lowest novelty seeking, RAN women the highest persistence and self-directedness, and PAN women the highest harm avoidance. Body mass index had a nominal effect on subgroup differences, suggesting that personality disturbances are independent of body weight. Findings suggest that certain facets of temperament differ markedly between women with AN, regardless of diagnostic subtype, and controls. More subtle temperament and character differences that were independent of body weight emerged that distinguish among subtypes of AN.     

Patterns of agreement among parent, teacher and youth ratings in a referred sample

ObjectiveThe purpose of this study was to investigate the degree of agreement among parents, teachers and adolescents with respect to the Child Behavior Checklist (CBCL), the Teacher's Report Form (TRF), and the Youth Self Report (YSR). In addition we evaluated the suitability of these three forms (CBCL, TRF and YSR) in terms of their contribution to understanding internalizing and externalizing disorders in youths being referred to a child and adolescent unit of a psychiatric care facility.MethodsA total of 611 patients aged 11–18 years (mean age 13.0, SD 1.6) were assessed using the CBCL, the TRF and the YSR.ResultsIntraclass coefficients (ICC) showed low to moderate agreement among informants. Furthermore, the level of agreement was generally less among patients suffering from internalizing disorders than for young patients who displayed externalizing disorders. Logistic regression revealed that the TRF internalizing syndrome scale, the CBCL internalizing syndrome scale and gender were relevant prognostic factors for the occurrence of internalizing disorders in youth. The YSR internalizing syndrome scale, on the other hand, was not a relevant factor among adolescents of a clinical target population. Likewise, only the TRF externalizing syndrome scale, the CBCL externalizing syndrome scale and gender were relevant prognostic factors for the occurrence of externalizing disorders in youth.ConclusionsParticularly the CBCL and TRF are useful instruments in assessing internalizing and externalizing disorders in adolescents referred to a mental health setting.     

Clinical characteristics and functions of non-suicide self-injury in youth

PurposeLittle is known about the clinical characteristics and motivations for engaging in non-suicide self-injury (NSSI) behaviors in adolescence. The aim of this study was to examine the prevalence, characteristics and functions of NSSI among adolescents in community settings, and to explore risk factors related to this behavior.Subjects and methodsTwo hundred and seventy-five adolescents aged 12 to 17 were recruited randomly from different High Schools in Israel. They completed self-report questionnaires assessing NSSI (Ottawa Self-Injury Inventory), depression (Children's Depression Inventory – CDI) and impulsivity (Barratt Impulsiveness Scale – BIS-II).ResultsIn the past year, 20.7% of the participants reported engaging NSSI at least once. Among them, 42.1% declared they are still engaging in NSSI at the present. Motives for NSSI were internal emotion regulation reasons, external emotion regulation reasons for social influences. In addition, the NSSI group reported significantly higher levels of depressive, impulsivity and suicidal ideations. Depressive symptoms were found as significant predictors of NSSI in the future.Discussion and conclusionsHigh rates of NSSI among community adolescents were found. Depression, impulsivity and suicidal ideation were found significantly related to NSSI. Mental health professionals in schools and in primary care should routinely assess NSSI among adolescents.     

Denial of symptoms and psychopathology in adolescent anorexia nervosa

OBJECTIVE: To evaluate the psychopathological status and denial of symptoms in a sample of 38 consecutively admitted adolescents with anorexia nervosa (AN). METHOD: The Schedule for Affective Disorders and Schizophrenia for School-Aged Children was used to determine the categorical diagnosis of eating disorder. The anorexic adolescents completed the EAT-40 (Eating Attitude Test) and, on the basis of its score, the sample was dichotomized in a false-negative group (FNG) scoring under 30 and a positive group (PG) scoring over 30. We compared these two subgroups in terms of clinical variables (age of onset and admission, duration of illness prior to admission, diagnosis, BMI) and psychopathology assessed by the CBCL (Child Behaviour Checklist) and the YSR (Youth Self-Report). In order to evaluate the possible role of diagnosis and BMI on the EAT score we also dichotomized the sample with respect to the diagnosis (full vs. partial AN) and to the mean female BMI (< or = 15 vs. > 15). RESULTS: A significant difference was found in terms of duration of illness prior to admission, which was briefer in the FNG. Higher CBCL and YSR values were found in the PG with significant differences in terms of YSR internalizing symptoms. A large amount of significantly positive Pearson's correlations were found between the CBCL and YSR values in the FNG. No significant Pearson's correlations were found between EAT, BMI and diagnosis. CONCLUSIONS: The lower CBCL and YSR values in the FNG seem to point out a tendency of this group to deny anxiety and depression as well as an eating pathology; the longer duration of illness prior to admission in the PG seems to support the hypothesis that the PG may be considered to be not so much more disturbed as more aware of its eating attitudes and psychopathology. The nature of denial in anorexic adolescents is discussed.     

Comparison of self-reported emotional and behavioral problems in Turkish immigrant,Dutch and Turkish adolescents

Abstract.Objective: The aim of this study was to compare self-reported emotional and behavioral problems for Turkish immigrant, native Dutch and native Turkish adolescents.Method: A total of 379 Turkish immigrant adolescents living in the Netherlands, and 1,039 Dutch adolescents from the general population completed the Dutch translation of the Youth Self-Report (YSR); 2,151 Turkish adolescents from the general population completed the Turkish translation of the YSR; parents of Turkish immigrant adolescents filled in the Turkish translation of the Child Behavior Checklist (CBCL/4–18).Results: Turkish immigrant adolescents scored themselves significantly higher than Dutch adolescents on five of the 11 YSR syndromes, most markedly on the Anxious/Depressed, Withdrawn and Internalizing scales. Dutch adolescents scored themselves higher than immigrant adolescents on the Somatic Complaints and Delinquent Behavior scales. Turkish immigrant adolescents scored themselves higher than Turkish adolescents on five of the 11 scales, most markedly on the Delinquent Behavior scale. Total problems scores for Turkish immigrant adolescents were higher than for Dutch and Turkish adolescents. Turkish immigrant adolescents scored themselves higher than their parents assessed them on seven of the 11 scales.Conclusion: Turkish immigrant adolescents reported more problems in comparison to their Dutch and native Turkish peers. Different patterns of parent-child interaction, family values and delay of Dutch language skills are considered to be responsible for these differences in scores.     

Reading the Mind in the Eyes: A Population-Based Study of Social Cognition in Older Adults

BackgroundSocial cognition indicates the cognitive processes involved in perceiving, interpreting, and processing social information. Although it is one of the six core DSM-5 cognitive domains for diagnosing neurocognitive disorders, it is not routinely assessed in older adults. The Reading the Mind in the Eyes Test assesses Theory of Mind, the social cognition mechanism which forms the root of empathy.ObjectivesTo describe the distribution of, and factors associated with, scores on a 10-item version of Reading the Mind in the Eyes Test (RMET-10) in older adults.DesignPopulation-based cross-sectional study.SettingSmall-town communities in Pennsylvania.ParticipantsAdults aged 66–105 years (N = 902, mean age = 76.6).MeasurementsThe assessment included RMET-10, demographics, cognitive screening, literacy, depression symptoms, anxiety symptoms, cognitive composites derived from a neuropsychological test battery, Social Norms Questionnaire, and Clinical Dementia Rating (CDR).ResultsRMET-10 score was normally distributed in our overall study sample. Normative RMET-10 scores among those rated as CDR = 0 were calculated by age, sex, and education. RMET-10 score was significantly higher with younger age, higher education, white race, higher cognitive screening scores, literacy, social norms scores, higher scores in all five domains in cognitive composites, and lower CDR. RMET-10 score was also significantly higher with fewer depression and anxiety symptoms after adjusting for demographics.ConclusionsThe RMET is a potentially useful measure of social cognition for use in the research assessment of older adults. With appropriate calibration it should also have utility in the clinical setting.     

Are there temperament differences between major depression and dysthymic disorder in adolescent clinical outpatients?

AimsThe aim of the study was to explore possible differences in temperament and character dimensions between 2 monodiagnostic adolescent groups of depression, namely, one with a present episode of major depression and subjects with the other being their dysthymic peers.SampleFrom a multisite Western Hungarian sample of consecutively referred 14- to 18-year-old new psychiatric adolescent outpatients, 2 groups were compared: group I, n = 56 (9 males, 47 females), with major depressive disorder (MDD) and group II, n = 27 (6 males, 21 females), with a diagnosis of dysthymic disorder (DD). All other comorbid diagnoses including bipolar and double depression (MDD + DD) cases were excluded. Present suicide events, if the attempter had an underlying diagnosis of depression, were not causes for exclusion. Assessment methods used were the adapted Hungarian versions of the Mini International Neuropsychiatric Interview and the Junior Temperament (Cloninger) Character Inventory.ResultsThe only difference between the major depressive and dysthymic adolescents was harm avoidance, adolescents with major depression having a higher level practice of harm avoidance, whereas the temperament type of MDD vs DD seems to differ only in the aspect of avoiding painful stress. Expectations regarding a worse degree of self-directedness and lower levels of persistence and cooperativeness in the MDD sample were not proved.ConclusionsNo essential temperament differences were found between the 2 adolescent depressive groups. Scarce differences between temperament qualities of MDD and DD may support Akiskal's continuum theory of depressive disorders. More research and the use of closer clinical personality typologies are warranted to explore possible personality trait differences (if they exist) between clinical diagnostic groups of adolescent patients.     

Temperament and character profiles are associated with depression outcome in psychiatric secondary care patients with harmful drinking

BackgroundTemperament and character profiles have been associated with depression outcome and alcohol abuse comorbidity in depressed patients. How harmful alcohol use modifies the effects of temperament and character on depression outcome is not well known. Knowledge of these associations could provide a method for enhancing more individualized treatment strategies for these patients.MethodsWe screened 242 depressed patients with at least moderate level of depressive symptoms. The Alcohol Use Disorders Identification Test (AUDIT) was used for identifying patients with marked alcohol use problems (AUP, AUDIT≥11). After 6 weeks of antidepressive treatment 173 patients were assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Temperament and Character Inventory (TCI-R). Outcome of depression (MADRS scores across three follow-up points at 6 weeks, 6 months and 24 months) was predicted with AUP, gender, and AUP x Gender and AUP x Time interactions together with temperament and character dimension scores in a linear mixed effects model.ResultsPoorer outcome of depression (MADRS scores at 6 weeks, 6 months and 24 months) was predicted by AUP × Time interaction (p = 0.0002) together with low Reward Dependence (p = 0.003). Gender and all other temperament and character traits were non-significant predictors of the depression outcome in the mixed effects model.ConclusionsPossibly due to the modifying effect of alcohol use problems, high Reward Dependence was associated with better depression treatment outcome at 6 months. Harm Avoidance and Self-Directedness did not predict depression outcome when alcohol use problems were controlled.     

Longitudinal covariance of resting-state cardiac function and borderline personality disorder symptoms in adolescent non-suicidal self-injury

Objectives: Cardiac function is altered in borderline personality disorder (BPD). In adolescents with non-suicidal self-injury (NSSI) resting heart rate (HR) and vagally mediated heart rate variability (vmHRV) are associated with BPD symptoms. The study aimed to investigate longitudinal covariance of BPD symptoms and cardiac function in adolescent NSSI.

Methods: HR and vmHRV were recorded in female adolescents with NSSI (n?=?17) completing a baseline and 1-year follow-up assessment. Physiological data, structured clinical interviews and self-reports were obtained at both time points. Predictors of change in clinical outcomes and cardiac function were assessed.

Results: Patients showed a reduction of NSSI (z_(34;17)?=?–3.79, P?z_(34;17)?=?–3.74, P?z_(34;17)?=?2.87, P?=?0.004). Symptoms of BPD and frequency of BPD diagnosis did not significantly change. No significant differences on HR or vmHRV were observed. Changes in BPD symptoms were associated with changes in HR (r₍₁₇₎= 0.532, P?=?0.028) and vmHRV (r₍₁₇₎?=?–0.516, P?=?0.033).

Conclusions: Longitudinal changes in BPD symptomatology in adolescents engaging in NSSI are associated with changes in resting cardiac function. Clinical studies are needed to investigate the utility of cardiac markers to track treatment outcome in adolescents with BPD.     

Harm avoidance and self-directedness as essential features of panic disorder patients

ObjectiveThe purpose of the study is to compare the personality traits assessed with the Temperament and Character Inventory (TCI) between patients with panic disorder (PD) and a control group in a Brazilian sample.MethodsOne hundred thirty-five patients with PD paired according to sex and age with 135 controls without any psychiatric disorders were assessed with the Mini International Neuropsychiatric Interview (MINI), a structured interview. Temperament and character were assessed with the TCI.ResultsConsistently, patients with PD presented higher scores on the harm avoidance (HA) temperament scale (23.20 ± 5.41 vs 15.21 ± 4.92; P < .001) and lower scores on the self-directedness (SD) (27.81 ± 7.25 vs 35.16 ± 5.47; P < .001) if compared to the control group and has been associated independently from other TCI scales and confounders with PD. The multivariate logistic model containing HA and SD explains 38.6% to 51.4% of the differences between PD and controls.ConclusionsHarm avoidance could be a good candidate to be heritable because it appears to be a consistent finding across current literature in anxious and depressed patients independent of their cultural context. Also, SD seems to be a key character characteristic of PD patients. The dimensional assessment is an interesting alternative for understanding the relationship between the psychobiologic bases of temperament and character and is highly related to the development of psychiatric syndromes.     

Personality Networks and Emotional and Behavioral Problems: Integrating Temperament and Character Using Latent Profile and Latent Class Analyses

Recent research indicates that adaptive functioning and well-being depends on the integration of three dissociable systems of learning and memory that regulate associative conditioning, intentionality and self-awareness. Our study objective was to describe how different integrated configurations of these systems (i.e. different expressions of personality) relate to the presence of internalizing, externalizing and total problems. In total, 699 adolescents completed the JTCI and Achenbach’s YSR. Latent profile analyses revealed two temperament profiles and six character profiles. Adolescents with a steady temperament, and those with healthy characters, were significantly less likely to present clinical levels of problems. The integration of a steady temperament and healthy character profiles in a Mature-Steady joint temperament-character network was also associated with significantly less clinical problems. In sum, our person-centered study indicates that adaptive expressions of associative conditioning, intentionality, and self-awareness (i.e. integrated personalities) are critical for mental health.
