Problematic Internet Use Among Adolescent Male and Female Psychiatric Inpatients: A Gender Perspective

Problematic internet use (PIU) is of treatment interest in adolescent clinical samples. Gender specific differences in terms of personality traits and psychopathological symptoms remain unclear. In an adolescent clinical sample (n = 104; 69 girls) PIU, psychopathology, temperament and character traits as well as emotional and behavioral problems were assessed. 62% of the sample showed subthreshold PIU and 34% full PIU (fPIU). Boys reported more gaming whereas girls social networking. Sex specific analyses revealed gender differences: Girls with fPIU scored significantly higher on internalizing/externalizing problems/behavior, novelty seeking and transcendence, and lower on persistence, self-directedness, and cooperativeness than girls without fPIU. Boys with fPIU scored significantly higher on internalizing problems and self-transcendence and lower on harm avoidance than boys without fPIU. Gender plays an important role in PIU. Gender specific differences in both application use as well as symptomatic, temperament and character traits call for a gender specific approach in prevention and treatment integration.

What Kind of Therapy Works With Juveniles Who Have Sexually Offended? A Randomized-Controlled Trial of Two Versions of a Specialized Cognitive Behavioral Outpatient Treatment Program

There is ongoing debate about whether specialized treatment is effective to reduce sexual recidivism in juveniles who have sexually offended (JSOs). Although most treatment programs are based on cognitive behavioral therapy principles for preventing sexual offending, accordant scientific evidence is poor. Following CONSORT guidelines, the present study aimed to evaluate two versions of a short-term outpatient treatment program for JSOs in Switzerland: (a) the Therapy Program for Adequate Sexual Behaviors Version 1 (ThePaS-I), which included offending-specific skills training; (b) the ThePaS-II, which included general socioemotional skills training. Based on changes in self-reported mental health, sexual behaviors, victim empathy, and therapist-rated risk, as well as comprehensive data on sexual and general recidivism, we found some similarities regarding the effects of the two treatments. ThePaS-II showed better short-term changes in self-reported mental health than the ThePaS-I. However, JSOs in the ThePaS-I showed lower rates of sexual reoffending (but not general reoffending) after treatment than those in the ThePaS-II. Despite some methodological limitations, the current findings favor offending-specific skills-based therapy over general skills-based ones for preventing sexual reoffenses. The findings may encourage further methodologically sound studies to examine different treatment approaches for juveniles and adults who have committed criminal offenses.

Sexualized Behavior Among Adolescents Who Sexually Offended

Early or excessive sexualized behaviors and preoccupations with sexuality (SB) exhibited by juveniles who have sexually offended (JSO) are considered risk factors for sexual recidivism. However, research into SB among JSO is scarce. The present study retrospectively examined prevalence rates and patterns of SB among JSO prior to sexual offending and their relation to psychopathology and sexual recidivism. We systematically assessed information from psychiatric and psychological expert reports in case files of 230 JSO aged 12-18 years (M = 14.46, SD = 1.49) from a population sample of JSO with contact sexual offenses. A total of 93 (40.4%) JSO exhibited SB prior to the index sexual offense. Latent class analysis revealed three SB profiles: (1) "low/no SB" (n = 188), (2) "preoccupied SB" (preoccupation with sexuality, e.g., early pornography consumption, excessive masturbation; n = 29), and (3) "dysregulated SB" (exhibiting inappropriate sexualized behaviors toward others, e.g., sexualized speech, touching others inappropriately; n = 13). The preoccupied SB and the dysregulated SB groups showed higher prevalence of psychiatric disorders than the low/no SB. However, none of the JSO of the preoccupied SB or dysregulated SB groups reoffended sexually within 365 days after conviction for the sexual index offense (low/no SB: 12.8%). Overall, our findings do not support a general notion of the presence of SB as an indicator of high risk for persistent sexual offending among JSO. Instead, JSO with SB appear particularly burdened regarding a range of psychiatric disorders that should be treated accordingly.

Temperament and Offending Behaviors in Male Adolescents

The aim of the current paper was to examine temperament profiles and temperament dimensions as risk factors for persistent criminal behavior in juveniles who offended (JOs). A sample of 137 male adolescents from a Swiss detention center and 137 age and sex matched community controls were included in the present study. Temperament was measured with the Junior Temperament and Character Inventory (JTCI). Using Latent Profile Analysis (LPA), three temperament profiles were found, a "moderate," an "adventurous-disinhibited" (higher levels of novelty seeking, lower levels of harm avoidance, reward dependence, and persistence), and a "worried-passive" profile (higher levels of harm avoidance, low persistence). None of the profiles and dimensions were associated with detention sample (i.e., JO) status. In JOs, the "novelty seeking" scale predicted recidivism after release from detention even when controlling for other covariates. Further research should address temperament profiles and temperament dimensions in larger samples of JOs to elaborate their relation to previous and future offending behavior.

Stability and change in a predictive model of emotional and behavioural problems from early adolescence to middle adulthood

The impact of negative life events, self-esteem, and coping behaviour are considered to be contributing factors in the development of emotional and behavioural problems. Differences in the predictive value of these three factors on emotional and behavioural problems from adolescence to adulthood have not yet been studied. Multiple linear regressions separate for the two sexes were used to assess whether the impact of negative life-events, self-esteem, and coping behaviour predicted emotional and behavioural problems at four discrete measurement points from early adolescence to middle adulthood in a cohort of N = 366 participants from a Swiss longitudinal community study. Mostly irrespective of sex, negative life-events and low self-esteem were significant predictors of internalizing problems, externalizing problems and total problem scores in adolescence as well as in adulthood. The explained variance in the model increased steadily from early adolescence to middle adulthood. While the impact of negative life-events was on the same level across all measurements until adulthood, the contribution of self-esteem increased steadily. There was a significant association, particularly in adolescent males, between avoidant coping and emotional and behavioural problems. The cross-sectional findings from this community study reflect long-term robust patterns in the associations of negative life-events, self-esteem, and avoidant coping with emotional and behavioural problems from adolescence to adulthood. Clinically, the three constructs represent actionable targets for optimizing assessment and intervention strategies across the adolescent life-span.

Associations of interpersonal trust with juvenile offending/conduct disorder, callous-unemotional traits, and criminal recidivism

Interpersonal trust has been described as a core dimension of cooperative, mutually beneficial interpersonal relationships but it is unclear if it is related to antisocial behaviours in youth. The present study aimed at analysing a subsample of male juveniles who committed serious violent offenses and met criteria of conduct disorder (JO/CD), and a subsample of healthy controls (HC) using a series of trust games (TGs). Twenty-four male JO/CD and 24 age matched male HC performed a series of eight one-shot TGs against different unknown human respectively computer opponents. Mixed model analyses found a non-significant trend that JO/CD invested less points than HC during TGs. In the subsample of JO/CD, the overall investment in TGs was found to be negatively associated with self-reported uncaring behaviours and officially reported general re-offenses. Our findings suggest some indication of an impaired ability of JO/CD to initiate mutually trusting relationships to others that should be addressed in further research. Trust is a promising factor to predict general criminal recidivism and can be a target for treatment of juveniles who committed violent offenses, for example through the building of stable relationships to care givers. This study encourages future studies to investigate the effects of trust-increasing psychosocial interventions.

Adverse Childhood Experiences, Personality, and Crime: Distinct Associations among a High-Risk Sample of Institutionalized Youth

Despite high rates of adverse childhood experiences (ACEs) and personality-related disturbances among delinquent juveniles, associations among ACEs, youth personality, and juvenile crime involvement are still unclear. High-risk samples of institutionalized youth are in specific need of a comprehensive assessment of ACEs and personality features in order to broaden the current knowledge on the occurrence and persistence of juvenile crime and to derive implications for prevention and intervention. We examined a heterogeneous high-risk sample of 342 adolescents (35.1% females, 64.9% males) aged between 12 and 18 years (M = 15.74, SD = 1.61 years) living in child-welfare or juvenile justice institutions regarding cumulative ACEs, psychopathic traits, temperament, and clinical personality disorder ratings, and criminal involvement before and up to 10 years after assessment. We found considerable rates of ACEs, although cumulative ACEs did not predict future crime. Latent Profile Analysis based on dimensional measures of psychopathy, temperament, and personality disorders derived six distinct personality profiles, which were differently related to ACEs, personality disturbances, clinical psychopathology, and future delinquency. A socially difficult personality profile was associated with increased risk of future crime, whereas avoidant personality traits appeared protective. Findings indicate that the role of ACEs in the prediction of juvenile delinquency is still not sufficiently clear and that relying on single personality traits alone is insufficient in the explanation of juvenile crime.

Validity of Risk Assessment Instruments Among Juveniles Who Sexually Offended: Victim Age Matters

Research has identified meaningful subtypes among the heterogeneous population of juveniles who sexually offended (JSO). However, studies that test the validity of risk assessment tools with JSO subtypes are limited. This study compared JSO who offended against a child victim (JSO-C) and JSO who offended against an adolescent/adult victim (JSO-A) with regard to rates of recidivism and the predictive validity of two risk assessment tools (Estimate of Risk of Adolescent Sexual Offense Recidivism [ERASOR] and Juvenile Sexual Offender Assessment Protocol-II [J-SOAP-II]). Data were analyzed from case files of 185 JSO-C and 297 JSO-A aged 12 to 18 years (M = 14.11, SD = 1.44) from a consecutive sample of JSO with contact sexual offenses. A total of 34 (7.1%) juveniles reoffended sexually, with no significant difference between the subtypes. The present results suggest that the ERASOR, particularly the structured professional judgment, and to a lesser degree the J-SOAP-II are better suited to predicting sexual recidivism in JSO-A than in JSO-C.

Predictors and outcomes of self-reported dysregulation profiles in youth from age 11 to 21 years

Understanding the dysregulation profile (DP) consisting of high scores in aggression, attention problems, and anxious/depressed problems is still limited. The aims of the present study were threefold: (a) to analyze developmental trajectories of DP (b) to identify predictors of these trajectories, and (c) to study the outcome of DP in terms of mental disorders and criminal offenses in young adulthood. A sample of 402 individuals aged 11-14 years at baseline was followed up during adolescence and young adulthood. Latent class growth analysis was used to identify DP based on the youth self-report and the young adult self-report. Self-related cognitions, perceived parental behavior, life events and coping served as predictors, psychiatric diagnoses and criminal convictions in young adulthood as outcomes. There were three developmental trajectories representing high, moderate, and low DP subgroups with 9.2% of participants represented by the high DP subgroup. Among predictors, self-esteem (negative), self-awareness (positive), and high numbers of life events had the most consistent effect on high DP. Affective and anxiety disorders and any mental disorder were significant outcomes of the high DP subgroup in both sexes at the time of young adulthood. This first report on DP based on longitudinal self-reports shows that DP is stable for a sizeable proportion of youth during adolescence and young adulthood. The predictors for DP share some similarity with those predicting psychopathology in general. However, so far there seems to be no heightened risk for the development of crime in the concerned individuals.

Selective attrition does not affect cross-sectional estimates of associations with emotional and behavioral problems in a longitudinal study with onset in adolescence

The present examination raises the question whether attrition in a longitudinal study leads to biased findings. The Zurich Adolescent Psychology and Psychopathology Study (ZAPPS) originated in 1994 by following a sample of 1239 adolescents with follow-ups after three, six, and 22 years. The study collected data on life-events, self-esteem, and coping behavior as independent and mental problems as dependent variables. The baseline sample was partitioned according to follow-up status for the three subsequent waves of assessment. Baseline measures of associations between independent and dependent variables were compared for those retained in the study (group A) and those lost to follow-up (group B) at each phase of cross-sectional data collection by use of multiple linear regression analyses. There were significant differences for some baseline independent variables between the two groups with small effect sizes. Males and migrants dropped out more frequently. The main findings indicated that the strength of the associations between independent and dependent variables at baseline in the total sample and in each of the two groups as defined by sample sizes at the three follow-ups was close to equal. Thus, one may conclude from the current study that attrition in longitudinal studies rarely affects cross-sectional estimates of associations.

Psychische Störungen und kriminelle Rückfälle bei männlichen jugendlichen Gefängnisinsassen

Zusammenfassung. Fragestellung: Die Prävalenz psychischer Störungen unter inhaftierten Jugendlichen ist hoch. Offen ist die Frage, ob damit eine erhöhte kriminelle Rückfälligkeit einhergeht. Methodik: Zwischen dem 01.08.2010 und 31.10.2012 wurden im kantonalen Jugendgefängnis Zürich alle inhaftierten männlichen Jugendlichen bei Eintritt psychiatrisch untersucht (N = 122). Die psychischen Störungen wurden anhand eines standardisierten Interviews erfasst. Nach der Haftentlassung wurden die Probanden im Kantonalen Rechtsinformationssystem betreffend Rückfälligkeit während eines Jahres nachkontrolliert. Ergebnisse: 90.2 % der Insassen litten unter mindestens einer psychiatrischen Störung. Über 70 % der Jugendlichen waren zum Zeitpunkt ihrer Inhaftierung von mehreren psychiatrischen Erkrankungen betroffen. Es konnten vier voneinander unabhängige Störungskategorien unterschieden werden: affektive Störungen, Angststörungen, Verhaltensstörungen und Abhängigkeitserkrankungen. Betreffend Rückfälligkeit fand sich, dass Jugendliche mit Verhaltensstörungen und/oder einer Abhängigkeitserkrankung häufiger mit einer Gewaltstraftat rückfällig wurden als aus dem Gefängnis entlassene Jugendliche ohne psychische Erkrankungen. Zudem zeigte sich, dass je jünger die inhaftierten Jugendlichen waren, desto kürzer war die Zeit nach ihrer Entlassung, bis sie eine Gewaltstraftat verübten. Schlussfolgerungen: Aufgrund der hohen Prävalenz von psychischen Störungen unter inhaftierten Jugendlichen ist es notwendig, dass diese Minderjährigen auch jugendpsychiatrisch-psychologisch untersucht und adäquat behandelt werden. Neben der psychiatrischen Versorgung der minderjährigen Gefängnisinsassen kann so auch den Anforderungen eines effektiven Opferschutzes und dem Sicherheitsbedürfnis unserer Gesellschaft entsprochen werden.

Patterns of Adverse Childhood Experiences in Juveniles Who Sexually Offended

Juveniles who sexually offended (JSOs) are differentially burdened with adverse childhood experiences (ACEs). The present study used Latent Class Analysis (LCA) to derive subtypes of JSOs according to their patterns of 10 different ACEs. An extensive file analysis of 322 male JSOs ( M = 14.14, SD = 1.94) revealed five subtypes with (a) multiple (9.0%), (b) mainly family related (17.1%), (c) mainly peer related (21.7%), (d) mainly neglectful (18.6%), and (e) little/no (33.5%) ACEs. Differences among ACE subtypes with regard to several offense and victim characteristics (e.g., the use of penetration or violence, the choice of a child, a male, a stranger, or multiple victims) were examined. Whereas no differences were found for the use of physical violence or the choice of male, stranger, or multiple victims, binary logistic regressions revealed associations of the multiple-ACE subtype with the choice of a child victim, the family-ACE subtype with the use of penetration as well as further nonsexual delinquency, the peer-ACE subtype with the use of penetration and the choice of a child victim, and the neglect-subtype with the choice of a child victim. Additional analyses including single ACE categories instead of LCA-derived subtypes supported these results. Findings highlight the need for a comprehensive consideration of ACEs in research and clinical work to understand developmental pathways to juvenile sexual offending.

Interferon regulatory factor-1 (IRF-1) activates the synthetic IRF-1-responsive sequence (GAAAGT)4 in Saccharomyces cerevisiae

In appropriate mammalian cells, interferon regulatory factor-1 (IRF-1) can activate the virus-responsive element of the IFN-beta promoter (VRE beta") or the synthetic oligonucleotide (GAAAGT)4. The latter contains two copies of the functional equivalent of PRDI, one of the regulatory domains of VRE beta". We prepared yeast strains containing an IRF-1 expression plasmid under the control of the galactose-inducible Gal1 promoter and a reporter plasmid with either (GAAAGT)4, VRE beta", or other test sequences placed upstream of a minimal promoter linked to the beta-galactosidase coding sequence. Upon induction of IRF-1 expression, the (GAAAGT)4-containing promoter was activated, but VRE beta" and all other sequences tested were inactive. Our results showed that IRF-1 belongs to a class of higher eukaryotic transcription factors that can interact with the yeast transcriptional machinery. Our findings also raised the question why the duplicate PRDI-like sequences in (GAAAGT)4 can be activated by IRF-1 synthesized in yeast, but not VRE beta", which also contains at least two PRDI-like sequences.

Testing the validity of criminal risk assessment tools in sexually abusive youth

Although accurate risk appraisals are mandatory to provide effective treatment to juveniles who have sexually offended (JSOs), the current knowledge on the validity of risk assessment instruments for JSOs is inconclusive. We compared the predictive validities of the Juvenile Sex Offender Assessment Protocol II (J-SOAP II), the Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR), and the Violence Risk Appraisal Guide-Revised (VRAG-R) scores concerning sexual, nonsexual-violent, and general criminal recidivism (based on both official and nonregistered reoffenses) in a consecutive sample of 597 male JSOs (Mage = 14.47 years, SDage = 1.57 years) while accounting for different recidivism periods, offense severities, and cumulative burden of adverse childhood experiences (ACEs). Receiver Operator Characteristic (ROC) curves and Cox regression analyses indicated that the tools allowed valid predictions of recidivism according to their intended purposes: The ERASOR was best suited to predict sexual recidivism within 0.5 and 3 years, the J-SOAP II was valid for predictions of sexual and nonsexual-violent recidivism within these recidivism periods, and the VRAG-R showed potential strengths in predicting nonsexual-violent recidivism, especially when committed above age 18. Elevated offense severity and burden of ACEs impeded predictive accuracies of the J-SOAP II and the VRAG-R, particularly in case of sexual recidivism. Our findings emphasize that risk assessment for JSOs must not rely solely on scores derived from risk assessment instruments, but a comprehensive consideration of a JSOs offense severity and psychosocial adversities is additionally necessary to approach accurate risk appraisals.

Type and timing of maltreatment influence criminal persistence in sexually abusive adolescents

The development of sexuality is a major goal in the normative course of puberty. However, some adolescents start and maintain sexually coercive behaviors. Maltreatment appears as a contributing factor in juvenile criminal persistence, although its role regarding reoffenses in juveniles convicted of sexual offenses (JSOs) is unclear. We examined time-dependent associations of maltreatment categories and subtypes with criminal persistence in JSOs. Files of 278 male JSOs (M = 14.64 years, SD = 1.58 years) were analyzed for experiences of emotional abuse, physical abuse, sexual victimization, emotional neglect, and physical neglect. We found 3 subtypes reflecting severe maltreatment, neglectful experiences, and low maltreatment. Severe maltreatment proved to be a consistent predictor of nonsexual criminal persistence, whereas overall neglectful experiences were related to sexual criminal persistence. More specifically, physical neglect (including lack of parental supervision) appeared of major importance for criminal persistence. Results indicate that maltreatment is a contributing factor in criminal persistence in JSOs and emphasize the potential gain of applying family oriented interventions to reduce criminal persistence in JSOs.

The contribution of parent and youth information to identify mental health disorders or problems in adolescents

BACKGROUND

Discrepancies between multiple informants often create considerable uncertainties in delivering services to youth. The present study assessed the ability of the parent and youth scales of the Strength and Difficulties Questionnaire (SDQ) to predict mental health problems/disorders across several mental health domains as validated against two contrasting indices of validity for psychopathology derived from the Development and Well Being Assessment (DAWBA): (1) an empirically derived computer algorithm and (2) expert based ICD-10 diagnoses.

METHODS

Ordinal and logistic regressions were used to predict any problems/disorders, emotional problems/disorders and behavioural problems/disorders in a community sample (n = 252) and in a clinic sample (n = 95).

RESULTS

The findings were strikingly similar in both samples. Parent and youth SDQ scales were related to any problem/disorder. Youth SDQ symptom and impact had the strongest association with emotional problems/disorder and parent SDQ symptom score were most strongly related to behavioural problems/disorders. Both the SDQ total and the impact scores significantly predicted emotional problems/disorders in males whereas this was the case only for the total SDQ score in females.

CONCLUSION

The present study confirms and expands previous findings on parent and youth informant validity. Clinicians should include both parent and youth for identifying any mental health problems/disorders, youth information for detecting emotional problems/disorders, and parent information to detect behavioural problems/disorders. Not only symptom scores but also impact measures may be useful to detect emotional problems/disorders, particularly in male youth.

Motivation to change, coping, and self-esteem in adolescent anorexia nervosa: a validation study of the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ)

BACKGROUND

Understanding motivation to change is a key issue in both the assessment and the treatment of eating disorders. Therefore, sound instruments assessing this construct are of great help to clinicians. Accordingly, the present study analysed the psychometric properties of the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), including its relation to coping style and self-esteem.

METHODS

N = 92 adolescents referred to an eating disorders outpatient clinic meeting criteria for anorexia nervosa gave written informed consent to participate in this study and completed the ANSOCQ, the Eating Disorder Inventory, the Eating Attitudes Test, the Body Image Questionnaire, two questionnaires measuring Self-Related Cognitions and the Coping Across Situations Questionnaire. After a treatment period of nine months, clinical anorexia nervosa diagnosis and the body mass index were re-assessed. In addition to exploratory factor analysis, correlational analysis was used to test for the convergent validity of the ANSOCQ and logistic regression analysis was used to test its predictive validity.

RESULTS

The ANSOCQ had good psychometric properties. Factor analysis yielded two meaningful factors labelled as 'weight gain and control' and 'attitudes and feelings'. Internal consistencies of the two factors amounted to Cronbach's alpha = .87 and .76, respectively. Significant correlations with other scales measuring eating disorder psychopathology were indicative of meaningful construct validity. Higher motivation to change was related to higher self-esteem and a more active coping style. Higher (positive) ANSOCQ total scores predicted remission of anorexia nervosa after nine months of treatment. A higher score on 'attitudes and feelings' was a protective factor against drop-out from intervention.

CONCLUSIONS

The ANSOCQ is a clinically useful instrument for measuring motivation to change in adolescents with AN. Two factorial dimensions explain most of the variation. Self-esteem and coping style are relevant additional constructs for the understanding of the motivation to change in anorexia nervosa.

The associations of cumulative adverse childhood experiences and irritability with mental disorders in detained male adolescent offenders

BACKGROUND

Adverse childhood experiences (ACEs) and psychiatric disorders are common in juvenile detainees. Emotional dysregulation resulting from cumulated ACEs may be characterized by symptoms of irritability. The present study examined whether the accumulation of ACEs, irritability, or both predicted mental disorders in incarcerated adolescents with and without controlling for one another and for socio-demographic factors.

METHODS

One hundred thirty male detained juvenile offenders (aged 13.8-19.5 years) were assessed by structured clinical interviews and a self-reporting scale for irritability. Univariate and multivariate regression models were used to examine the shared and distinct associations of ACEs and irritability with psychiatric diagnoses.

RESULTS

A total of 75 % of the participants reported more than one ACE. The ACE total score was positively related to self-reported irritability. The ACE total score predicted depressive disorders, suicidality, post-traumatic stress disorder (PTSD), and anxiety disorders. Irritability was positively related to depressive disorders, suicidality, disruptive behavior disorder (DBD), substance use disorder (SUD), and attention deficit hyperactivity disorder (ADHD). These associations remained significant in multivariate models.

CONCLUSIONS

This study provides evidence for the predictive impact of self-reported ACEs and irritability with regard to adolescent psychiatric disorders in young male inmates. Both variables differed in their predictive power for PTSD, internalizing, and externalizing disorders indicating the need for specific therapeutic interventions. Taking a close look at their trauma history seems to be of special importance for juveniles suffering from PTSD and anxiety disorders. For delinquent adolescents with DBD, ADHD and SUD, the training of emotion regulation techniques appears most promising. Approaches focusing on both, ACEs and emotion-focused contents may be implemented in the treatment of depressive disorders and suicidality.

[Inherited thrombopathia in Simmental cattle]

During the years 2012 to 2014, a total of 5 affected Simmental cattle showing persistent bleeding after minor or unknown trauma, were presented at the Clinic for Ruminants or at the Institute for Genetics of the Vetsuisse-Faculty, University of Berne. The homozygous mutation RASGRP2, initially reported in 2007, was present in all these cases and all available parents were heterozygous carriers thus confirming the recessive mode of inheritance. Three affected animals died as a result of persistent bleeding. One animal was stabilized at the Clinic for Ruminants and was slaughtered one month later. Another case showing persistent bleeding and several hematomas was euthanized after genotyping. A frequency of 10% carriers for the associated mutation was detected in a sample of 145 Simmental sires which were used 2013 for artificial insemination in Switzerland. These bulls are designated as TP carriers and should not be used uncontrolled. Breeding organizations in Switzerland make use of the gene test to select bulls which do not carry the mutation.

Stochastic Discounting, Aggregate Claims, and the Bootstrap

Obtaining good estimates for the distribution function of random variables like (‘perpetuity’) and (‘aggregate claim amount’), where the (Yi), (Zi) are independent i.i.d. sequences and (N(t)) is a general point process, is a key question in insurance mathematics. In this paper, we show how suitably chosen metrics provide a theoretical justification for bootstrap estimation in these cases. In the perpetuity case, we also give a detailed discussion of how the method works in practice.

Genome-wide analyses of aggressiveness in attention-deficit hyperactivity disorder

Aggressiveness is a behavioral trait that has the potential to be harmful to individuals and society. With an estimated heritability of about 40%, genetics is important in its development. We performed an exploratory genome-wide association (GWA) analysis of childhood aggressiveness in attention deficit hyperactivity disorder (ADHD) to gain insight into the underlying biological processes associated with this trait. Our primary sample consisted of 1,060 adult ADHD patients (aADHD). To further explore the genetic architecture of childhood aggressiveness, we performed enrichment analyses of suggestive genome-wide associations observed in aADHD among GWA signals of dimensions of oppositionality (defiant/vindictive and irritable dimensions) in childhood ADHD (cADHD). No single polymorphism reached genome-wide significance (P < 5.00E-08). The strongest signal in aADHD was observed at rs10826548, within a long noncoding RNA gene (beta = -1.66, standard error (SE) = 0.34, P = 1.07E-06), closely followed by rs35974940 in the neurotrimin gene (beta = 3.23, SE = 0.67, P = 1.26E-06). The top GWA SNPs observed in aADHD showed significant enrichment of signals from both the defiant/vindictive dimension (Fisher's P-value = 2.28E-06) and the irritable dimension in cADHD (Fisher's P-value = 0.0061). In sum, our results identify a number of biologically interesting markers possibly underlying childhood aggressiveness and provide targets for further genetic exploration of aggressiveness across psychiatric disorders. © 2016 The Authors.

Gene-set and multivariate genome-wide association analysis of oppositional defiant behavior subtypes in attention-deficit/hyperactivity disorder

Oppositional defiant disorder (ODD) is a frequent psychiatric disorder seen in children and adolescents with attention-deficit-hyperactivity disorder (ADHD). ODD is also a common antecedent to both affective disorders and aggressive behaviors. Although the heritability of ODD has been estimated to be around 0.60, there has been little research into the molecular genetics of ODD. The present study examined the association of irritable and defiant/vindictive dimensions and categorical subtypes of ODD (based on latent class analyses) with previously described specific polymorphisms (DRD4 exon3 VNTR, 5-HTTLPR, and seven OXTR SNPs) as well as with dopamine, serotonin, and oxytocin genes and pathways in a clinical sample of children and adolescents with ADHD. In addition, we performed a multivariate genome-wide association study (GWAS) of the aforementioned ODD dimensions and subtypes. Apart from adjusting the analyses for age and sex, we controlled for "parental ability to cope with disruptive behavior." None of the hypothesis-driven analyses revealed a significant association with ODD dimensions and subtypes. Inadequate parenting behavior was significantly associated with all ODD dimensions and subtypes, most strongly with defiant/vindictive behaviors. In addition, the GWAS did not result in genome-wide significant findings but bioinformatics and literature analyses revealed that the proteins encoded by 28 of the 53 top-ranked genes functionally interact in a molecular landscape centered around Beta-catenin signaling and involved in the regulation of neurite outgrowth. Our findings provide new insights into the molecular basis of ODD and inform future genetic studies of oppositional behavior. © 2015 The Authors.

Oppositional defiant disorder dimensions and subtypes among detained male adolescent offenders

BACKGROUND

In adolescent offenders, oppositional defiant disorder (ODD) and its dimensions/subtypes have been frequently ignored due to the stronger focus on criminal behaviours. The revised criteria of the DSM-5 now allow diagnosing ODD in older youths independent of conduct disorder (CD). This study aimed at analysing ODD dimensions/subtypes and their relation to suicidality, comorbid psychiatric disorders, and criminal behaviours after release from detention in a sample of detained male adolescents.

METHODS

Suicidality and psychiatric disorders (including ODD symptoms) were assessed in a consecutive sample of 158 male adolescents (Mage  = 16.89 years) from the Zurich Juvenile Detention Centre. Based on previous research findings, an irritable ODD dimension and a defiant/vindictive ODD dimension based on ODD symptoms were defined. Latent Class Analysis (LCA) was used to identify distinct subtypes of adolescent offenders according to their ODD symptom profiles. Logistic regression and Cox regression were used to analyse the relations of ODD dimensions/ODD subtypes to comorbid psychopathology and criminal reoffenses from official data.

RESULTS

The ODD-irritable dimension, but not the ODD defiant/vindictive dimension predicted comorbid anxiety, suicidality and violent reoffending. LCA identified four subtypes, namely, a no-ODD subtype, a severe ODD subtype and two moderate ODD subtypes with either defiant or irritable symptoms. The irritable ODD subtype and the severe ODD subtype were related to suicidality and comorbid affective/anxiety disorders. The irritable ODD subtype was the strongest predictor of criminal (violent) reoffending even when controlling for CD.

CONCLUSIONS

The present findings confirm the presence of ODD dimensions/subtypes in a highly disturbed adolescent offender sample. Irritable youths were at risk of suicide and persistent criminal behaviours. Due to the severe consequences of irritability, a standardized assessment approach and a specific treatment is needed in prison to prevent suicide among the detainees and further harm to the society. As defined in the DSM-5, the present findings confirm the validity of ODD and ODD dimensions/subtypes as a diagnostic category among older youths.

[Pilot study on the effectiveness of a multimodal group treatment for children with oppositional defiant disorder in clinical primary care]

Aim

Pilot study on the effectiveness of a multimodal group treatment for children with oppositional defiant disorder in clinical primary care.

Objective

Oppositional defiant disorder (ODD) is a frequent disorder in children and a common cause for referral to child psychiatric services. ODD consists of irritability, headstrongness and hurtful behaviours. The aim of the pilot study was to assess the effectiveness of combined cognitive-behavioural group interventions – the Baghira group training for the children and the Positive Parenting Program Triple P – in an outpatient child psychiatric service.

Method

42 children with ODD who attended the combined interventions were compared to 26 untreated probands in a waiting list control group. Externalizing problem behaviour, aggression and delinquency were assessed at treatment begin, treatment end and at the 6-month follow-up with questionnaires for the children, parents and teachers.

Results

In comparison to the waiting list control group in the treatment group parent-reported externalizing problems decreased significantly between pre- and posttreatment assessment. A trend to significance was found for the decrease of teacher reported delinquency. Medium effect sizes were found and all effects were stable at follow-up.

Conclusions

In this pilot study the combined interventions have shown to be effective in clinical primary care for the treatment of ODD and beneficial for the children and their families. For the assessment of the specific effectiveness of the Baghira group training further and larger studies are required.

[Psychosocial disadvantages in incarcerated girls and boys]

OBJECTIVE

Longitudinal studies found that criminal behavior in juveniles often concurs with neighborhood disadvantage and family dysfunction, especially in girls. In this study we assessed the psychosocial background in incarcerated juveniles and analyzed the data for each gender separately.

METHOD

The Multidimensional Clinical Screening Inventory for delinquent juveniles (MCSI) was used to assess school history, psychiatric history, family background, abuse and neglect and motive for crime. The sample consisted of 294 juveniles (46 females and 248 males).

RESULTS

Innerfamilial abuse/neglect was reported by 91% (girls) and 79% (boys). 76% (girls) and 88% (boys) reported school-problems. 57% (girls) and 29% (boys) reported to have recieved psychiatric pretreatment. In girls we found significantly higher prevalence rates for parental divorce, incarceration of mother, abuse/neglect and psychiatric pretreatment. Significantly more girls reported a co-occurrence of school-problems and experiences of separation and loss and abuse (65.2% vs. 46.4%, χ²=5.51, df=1, p<.05).

CONCLUSION

Incarcerated juveniles, especially females, are and have been exposed to multiple psychosocial burdens. Therefore it is necessary to implement prevention programs for psychosocially stressed families. Forensic intervention in and after detention has to include a family centered approach.

Testing the "Sexually Abused-Abuser Hypothesis" in Adolescents: A Population-Based Study

A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths.

Criminal history and future offending of juveniles convicted of the possession of child pornography

Most child pornography is distributed online. It is estimated that 3% to 15% of child pornography consumers are juveniles. The present study analyzed a consecutive sample of 54 male juveniles convicted of the possession of child pornography. Demographic characteristics, criminal history, and subsequent offending were assessed from criminal files and official reports. Juvenile possessors of child pornography were compared to three different groups of juveniles: Juvenile possessors of other illegal pornography (n = 42), juveniles who committed a sexual contact offense against a child (n = 64), and juveniles who committed a sexual contact offense against a peer or adult (n = 104). Juvenile possessors of child pornography were found to have downloaded the illegal material more frequently and over a longer time period than juvenile possessors of other illegal pornography. Furthermore, juvenile possessors of child pornography differed from juveniles who had committed a sexual contact offense in terms of demographics and showed fewer previous and subsequent offending than juveniles who sexually offended against a peer or adult. We conclude that juvenile possessors of child pornography need a specific target intervention focusing on dysfunctional Internet use and sexually deviant arousal.

Problem coping skills, psychosocial adversities and mental health problems in children and adolescents as predictors of criminal outcomes in young adulthood

The purpose of this study was to test child and adolescent psychosocial and psychopathological risk factors as predictors of adult criminal outcomes in a Swiss community sample. In particular, the role of active and avoidant problem coping in youths was analysed. Prevalence rates of young adult crime convictions based on register data were calculated. Univariate and multivariate logistic regressions were used to analyse the prediction of adult criminal convictions 15 years after assessment in a large Swiss community sample of children and adolescents (n = 1,086). Risk factors assessed in childhood and adolescence included socio-economic status (SES), migration background, perceived parental behaviour, familial and other social stressors, coping styles, externalizing and internalizing problems and drug abuse including problematic alcohol consumption. The rate of any young adult conviction was 10.1 %. Besides externalizing problems and problematic alcohol consumption, the presence of any criminal conviction in young adulthood was predicted by low SES and avoidant coping even after controlling for the effects of externalizing problems and problematic alcohol use. The other predictors were significant only when externalizing behaviours and problematic alcohol use were not controlled. In addition to child and adolescent externalizing behaviour problems and substance use, low SES and inadequate problem-solving skills, in terms of avoidant coping, are major risk factors of young adult criminal outcomes and need to be considered in forensic research and criminal prevention programs.

Parent- and self-reported dimensions of oppositionality in youth: construct validity, concurrent validity, and the prediction of criminal outcomes in adulthood

BACKGROUND

Different dimensions of oppositional defiant disorder (ODD) have been found as valid predictors of further mental health problems and antisocial behaviors in youth. The present study aimed at testing the construct, concurrent, and predictive validity of ODD dimensions derived from parent- and self-report measures.

METHOD

Confirmatory factor analyses were performed to test a three-dimensional model (ODD-irritability, ODD-headstrong, and ODD-hurtful) and a two-dimensional model (ODD-irritability, ODD-headstrong/hurtful) based on items of the Child Behavior Checklist (CBCL) and the Youth Self Report (YSR) collected in a Swiss community study of 1,031 adolescents (519 boys, 512 girls) aged between 10.7 and 17.9 (M = 13.85, SD = 1.63) years. Logistic regression analyses were applied to predict scores in the clinical range of concurrent CBCL/YSR-anxiety/depression, CBCL/YSR-attention problems, and CBCL/YSR-delinquent behavior and depression as measured by the Center for Epidemiological Studies Depression Scale (CES-D) as well as to predict the presence of adult criminal convictions.

RESULTS

CFA findings were in favor of a three-dimensional model rather than a two-dimensional model of ODD. The CBCL/YSR-ODD-irritability scale was related to concurrent self-reported depression, but also to attention problems and delinquent behavior. CBCL/YSR-ODD-hurtful and less strongly also the combined YSR-headstrong/hurtful scale predicted adult criminal outcomes.

CONCLUSIONS

As proposed by the DSM-5 workgroup, different ODD-dimensions were confirmed by the present study. ODD-irritability predicts psychiatric comorbidity and ODD-hurtful symptoms should be specifically considered in youth at risk for criminal outcomes.

Spine Tango annual report 2012

PURPOSE

Since the Spine Tango registry was founded over a decade ago it has become established internationally. An annual report has been produced using the same format as the SWEspine group to allow for first data comparisons between the two registries.

METHODS

Data was captured with the latest generation of surgery and follow-up forms. Also, the Core Outcome Measures Index (COMI) from interventions performed in the year 2012 with follow-up to June 2013 was analyzed. Groups of patients with the most common degenerative lumbar spine diseases and a single group of patients with degenerative cervical spine diseases were created. The demographics, risk factors, previous treatments, current treatment, short-term outcomes, patient satisfaction and complications were analyzed. Pre- and postoperative pain and function scores were derived from the COMI.

RESULTS

About 6,500 procedures were captured with Spine Tango in 2012. The definitions and composition of all the degenerative groups could not completely be matched between the two registries with the consequence that the age and sex distributions were partially different. Preoperative pain levels were similar. The short-term outcomes available did not allow for evaluation of the final result of surgical intervention. This will be possible with the longer term data in the next annual report. There was a distinct disparity in reported complication rates between surgeons and patients.

CONCLUSIONS

This is a valuable first step in creating comparable reports for SWEspine and Spine Tango. The German spine registry may be able to collaborate in the future because of similar items and data structure as Spine Tango. There needs to be more work on understanding the harmonization of the different degenerative subgroups. The Spine Tango report is weakened by the short and incomplete follow-up. The visual presentation of data may be a useful model for aiding decision making for surgeons and patients in the future.

Internalizing and externalizing problems, depression, and self-esteem in non-detained male juvenile offenders

BACKGROUND

High rates of mental disorders have been found in detained juvenile offenders, whereas the role of psychopathology in non-detained offenders is less clear. Therefore, the present study compared psychopathology in male non-detained delinquent juveniles and two matched samples from the community and an adolescent psychiatric clinic.

METHODS

125 male adolescents aged 11 to 19 years (m = 16.2 years, SD = 1.5 years) from an outpatient adolescent forensic clinic were compared to a community sample from the Zurich Adolescent Psychology and Psychopathology Study (ZAPPS) and a referred sample from a psychiatric clinic matched for age and nationality. All subjects responded to questionnaires measuring internalizing and externalizing problems, depressive symptoms and self-esteem.

RESULTS

The sample of non-detained juvenile offenders showed similar rates of self-reported internalizing and externalizing problems when compared to the community sample, whereas the clinic sample displayed an increased rate of various disturbances. Similar results were found also for self-esteem. In agreement with these findings, non-detained juvenile offenders less frequently had a psychiatric diagnosis after full clinical assessment when compared to the clinical sample. However, a diagnosis of conduct disorders and a lower IQ range was found more frequently in non-detained juvenile offenders. Offenders with serious delinquent acts and involving weapons showed higher depression scores than the rest of the offenders.

CONCLUSION

In non-detained assessment situations before court examination, juvenile offenders present rather normal behaviour. Their lack of awareness of potential behavioural problems should be considered during assessment and treatment of this group of offenders.

The use of the development and well-being assessment (DAWBA) in clinical practice: a randomized trial

The development and well-being assessment (DAWBA) has been used in various epidemiological studies, whereas the clinical value of the instrument needs support from further studies. In particular, it is important to document how the use of the DAWBA influences clinical decision-making. The present study employed the DAWBA in a consecutive series of 270 new referrals to a large public child and adolescent psychiatric service in Zurich, Switzerland. ICD-10 based diagnoses were obtained from clinicians for all patients and reliability of DAWBA expert raters was calculated. The DAWBA diagnoses were randomly disclosed (n = 144) or not disclosed (n = 126) before clinical decision-making. The reliability of DAWBA expert diagnoses was very satisfactory and the agreement under the disclosed versus the non-disclosed condition amounted to 77 versus 68% for internalizing disorders and to 63 versus 71% for externalizing disorders. The increment in agreement due to disclosure of the DAWBA diagnosis was significant for internalizing disorders. Access to DAWBA information was more likely to prompt clinicians to add an extra diagnosis. Professional background and degree of clinical experience did not affect diagnostic agreement. Overall, diagnostic agreements between DAWBA expert diagnoses and clinical diagnoses were in the fair to moderate range and comparable to previous studies with other structured diagnostic interviews. The inclusion of the DAWBA into the clinical assessment process had an impact on diagnostic decision-making regarding internalizing disorders but not regarding externalizing disorders.

Minimally invasive management of thoraco-lumbar fractures: combined percutaneous fixation and balloon kyphoplasty

STUDY DESIGN

Retrospective review of prospectively collected data.

BACKGROUND

There is no consensus regarding the ideal treatment of thoraco-lumbar spine fractures without neurological compromise. Many surgical techniques have been described but none has proved its definite superiority. The main drawback of these procedures is directly related to the morbidity of the approach. As minimally invasive fixation combined with balloon kyphoplasty for treatment of thoraco-lumbar fractures is gaining popularity, its efficacy has yet to be established.

PURPOSE

The purpose of this study is to report operative data, clinical and radiological outcomes of patients undergoing minimally invasive management of thoraco-lumbar fracture at our institutions.

METHODS

Forty-one patients underwent percutaneous kyphoplasty and stabilization for treatment of single-level fracture of the thoracic or lumbar spine. All patients were neurologically intact. There were 20 males and 21 females with an average age of 50 years.

RESULTS

The mean follow-up was 15 months (3-90 months). The mean operative time was 102 minutes (range 35-240 minutes) and the mean blood loss was <100mL. VAS was significantly improved from 6.7 to 0.7 at last follow-up. Vertebral kyphosis decreased by 16° to 7.8° postoperatively (P<0.001). Local kyphosis and percentage of collapse were also significantly improved from 8° to 5.6° and from 35% to 16% at last follow-up. Fifteen leaks have been identified, three of which were posterior; all remained asymptomatic. No patient worsened his or her neurological condition postoperatively.

CONCLUSION

Percutaneous stabilization plus balloon kyphoplasty seems to be a safe and effective technique to manage thoraco-lumbar fractures without neurological impairment.

Psychopathology and offense types in detained male juveniles

A substantial proportion of violent crime is committed by juveniles. In detained juveniles, high rates of psychopathology have been found. The objective of this study was to determine psychopathology associated with offense characteristics in detained male adolescents. The Mini International Neuropsychiatric Interview was used to assess juvenile detainees. The final sample included 275 males (mean age=16.45, S.D.=1.27 years). Multivariate logistic regressions yielded significant associations between psychopathology and specific offense types: The presence of substance use disorders (without alcohol) (SUD) was found to predict drug-related crimes, and the presence of alcohol use disorders (AUD) without further SUD were a predictor of violent crime, especially in older juveniles. The absence of anxiety disorder, especially in younger juveniles, was found to be relevant for the prediction of robbery. The results of the study suggest that the use and abuse of legal and illegal substances might be a trigger for serious violent and drug-related crimes in juveniles. In particular, the presence of AUD is presumed to have a pivotal role in the development of impulsive aggression. These findings are important when considering the serious social impact of violent behaviors in adolescents.

Offender types and criminality dimensions in male juveniles convicted of sexual offenses

Previous studies have described juveniles who sexually offended (JSO) as a rather heterogeneous population. In consequence, different typologies of JSO have been proposed for a better understanding of the causes and interventional needs of JSO. Three previously described types have received support in previous studies, namely, the victim age type (JSO offending against children vs. adolescents or adults), the co-offender status type (JSO offending as singles vs. in groups), and the crime history type (JSO with vs. without a previous history of crime). The validity of these types is tested in a consecutive sample of 223 criminal male adolescents, who had been convicted of a sexual offense between 2000 and 2008 in the Canton of Zurich (Switzerland). By analyzing nine offender characteristics, four victim characteristics and six offense characteristics, the best evidence is found for the victim age-based type. The co-offender status and the crime history types are less well supported. However, all three types are related to each other and do not provide a comprehensive characterization of JSO. Therefore, an additional principal component analyses is performed searching for basic dimensions of juvenile sexual delinquency and leading to the following factors: "single offender with severe molestation of a related child," "persistent general delinquent with migrant background," "older offender with alcohol use and familial constraints," "multiple and aggressive offender with social adversities," and "offender with unselected and multiple victims." These five dimensions reflect different relevant factors of sexual offending behavior in male juveniles and may have further impact on forensic and clinical practice.

Predicting sexual and nonsexual recidivism in a consecutive sample of juveniles convicted of sexual offences

Reliable and valid risk assessments are essential for responding adequately to juveniles who have sexually offended (JSO). Given the lack of specific research focusing on the JSO population, the present study aims at confirming and expanding previous findings based on clinical samples dealing with risk assessments of JSO. The predictive power of the Juvenile Sex Offender Assessment Protocol (J-SOAP-II) and the Sexual Offence Severity (SOS) Scale are evaluated retrospectively by analyzing forensic, police, and judicial files in a consecutive sample of 223 adolescents (mean age of 15.7 years, SD=2.1 years) who had been convicted of a sexual crime in the Canton of Zurich, Switzerland, between 2000 and 2008. Based on local official recidivism data (mean follow-up period=4.3 years; SD=2.5 years), univariate and multivariate predictions of sexual and nonsexual recidivism are tested by use of the J-SOAP-II and the SOS Scale in logistic regression and receiver operating characteristics (ROC) analyses. Sexual recidivism (n=7, 3.1%) is best predicted by a multivariate model, including the J-SOAP-II Adjustment Scale and the SOS Scale (ROC: Area under the curve [AUC]=.818). Nonsexual violent (n=37, 16.6%) and general recidivism (n=100, 44.8%) are only moderately predicted by the J-SOAP-II impulsive/antisocial behavior scale (AUC=.677 and .662, respectively). In conclusion, the J-SOAP-II adjustment scale, the J-SOAP-II impulsive/antisocial behavior scale, and the SOS Scale may be helpful for screening purposes in JSO, but additional risk assessment seems necessary. Overall, further research is necessary for a comprehensive understanding of risk factors in JSO.

Psychopathologische und komorbide Störungen inhaftierter Jugendlicher in Österreich

Fragestellung: Inhaftierte Jugendliche zeigen hohe Prävalenzraten an psychiatrischen Störungen und gehäuft psychiatrische Komorbidität. Im Strafvollzug tätige Kinder- und JugendpsychiaterInnen stehen vor der Versorgungsaufgabe und der Notwendigkeit, störungsspezifische Behandlungsansätze auszuarbeiten. Die in dieser Studie erhobenen psychiatrischen Störungen bei inhaftierten Jugendlichen wurden im Hinblick auf störungsspezifische Behandlungsaspekte geschlechtsspezifisch ausgewertet. Methodik: Das Mini International Neuropsychiatric Interview für Kinder und Jugendliche wurde angewandt, um die Psychopathologie bei in Österreich inhaftierten Jugendlichen zu erheben. Die endgültige Stichprobe umfasste 333 Jugendliche (58 Mädchen und 275 Jungen). Ergebnisse: 90 % der inhaftierten Jugendlichen litten an mindestens einer psychiatrischen Störung, über 60 % zeigten zwei oder mehr koexistierende Störungsbilder. Mittels Faktorenanalyse wurden für männliche Jugendliche drei klinisch relevante Störungsmuster anhand von psychopathologischen Merkmalen ausgearbeitet: ADHS/Störung des Sozialverhaltens und Drogenmissbrauch; Angst und Depression; Trennungsangst/PTBS und Alkoholmissbrauch. Für weibliche Jugendliche ergaben sich vier Störungsmuster: Trennungsangst/Sozialphobie/Dysthymie; PTBS und Drogenmissbrauch in Kombination mit entweder ADHS oder Störung des Sozialverhaltens; Depression und Alkoholmissbrauch. Schlussfolgerungen: Aufgrund der hohen Raten an Psychopathologien bei inhaftierten Jugendlichen ist eine umfassende und strukturierte Diagnostik unerlässlich für die weitere Behandlungsentscheidung, da bei inhaftierten Jugendlichen verschiedene Störungsmuster berücksichtigt werden müssen. Die gefundenen Störungsmuster könnten im Zusammenhang mit der Entstehung delinquenten Verhaltens, mit unterschiedlichen Behandlungsbedürfnissen und mit dem Risiko für erneute Delikte wichtig sein.

A lectin-mediated resistance of higher fungi against predators and parasites

Fruiting body lectins are ubiquitous in higher fungi and characterized by being synthesized in the cytoplasm and up-regulated during sexual development. The function of these lectins is unclear. A lack of phenotype in sexual development upon inactivation of the respective genes argues against a function in this process. We tested a series of characterized fruiting body lectins from different fungi for toxicity towards the nematode Caenorhabditis elegans, the mosquito Aedes aegypti and the amoeba Acanthamoeba castellanii. Most of the fungal lectins were found to be toxic towards at least one of the three target organisms. By altering either the fungal lectin or the glycans of the target organisms, or by including soluble carbohydrate ligands as competitors, we demonstrate that the observed toxicity is dependent on the interaction between the fungal lectins and specific glycans in the target organisms. The toxicity was found to be dose-dependent such that low levels of lectin were no longer toxic but still led to food avoidance by C. elegans. Finally, we show, in an ecologically more relevant scenario, that challenging the vegetative mycelium of Coprinopsis cinerea with the fungal-feeding nematode Aphelenchus avenae induces the expression of the nematotoxic fruiting body lectins CGL1 and CGL2. Based on these findings, we propose that filamentous fungi possess an inducible resistance against predators and parasites mediated by lectins that are specific for glycans of these antagonists.

Predictability of oppositional defiant disorder and symptom dimensions in children and adolescents with ADHD combined type

BACKGROUND

Oppositional defiant disorder (ODD) is frequently co-occurring with attention deficit hyperactivity disorder (ADHD) in children and adolescents. Because ODD is a precursor of later conduct disorder (CD) and affective disorders, early diagnostic identification is warranted. Furthermore, the predictability of three recently confirmed ODD dimensions (ODD-irritable, ODD-headstrong and ODD-hurtful) may assist clinical decision making.

METHOD

Receiver-operating characteristic (ROC) analysis was used in order to test the diagnostic accuracy of the Conners' Parent Rating Scale revised (CPRS-R) and the parent version of the Strength and Difficulties Questionnaire (PSDQ) in the prediction of ODD in a transnational sample of 1093 subjects aged 5-17 years from the International Multicentre ADHD Genetics study. In a second step, the prediction of three ODD dimensions by the same parent rating scales was assessed by backward linear regression analyses.

RESULTS

ROC analyses showed adequate diagnostic accuracy of the CPRS-R and the PSDQ in predicting ODD in this ADHD sample. Furthermore, the three-dimensional structure of ODD was confirmed by confirmatory factor analysis and the CPRS-R emotional lability scale significantly predicted the ODD irritable dimension.

CONCLUSIONS

The PSDQ and the CPRS-R are both suitable screening instruments in the identification of ODD. The emotional lability scale of the CPRS-R is an adequate predictor of irritability in youth referred for ADHD.

Accuracy of the DSM-oriented attention problem scale of the child behavior checklist in diagnosing attention-deficit hyperactivity disorder

OBJECTIVE

The present study aimed at testing the Child Behavior Checklist (CBCL) including an adapted five-item DSM-Oriented Attention Problem Scale for predicting attention deficit hyperactivity disorders (ADHD).

METHODS

CBCL ratings were made both in a community sample (N = 390) and an outpatient child psychiatric sample (N = 392). Four different prediction models were analyzed in a community subsample (n = 195) and an outpatient subsample (n = 196) and cross-validated in two further subsamples of the same size.

RESULTS

The adapted DSM-Oriented Attention Problem Scale was superior to the original Attention Problem Scale in the identification of ADHD participants. A raw score of 5 to 6 on the reduced DSM-Oriented Attention Problem Scale was the best discriminator between cases and noncases.

CONCLUSIONS

The adapted DSM-Oriented Attention Problem Scale of the CBCL is a useful screening instrument for ADHD with adequate diagnostic accuracy in community and outpatient samples. (J. of Att. Dis. 2010; 13(5) 454-463).
