Correlates of aggressive and delinquent conduct problems in adolescence

The primary purpose of the study was to test a hypothetical model for aggressive and delinquent conduct problems in adolescence. A total of 168 adolescents from 121 families were studied using several questionnaires and a semi‐structured interview. The following factors were considered: obstetric complications, temperament (novelty‐seeking), self‐esteem, family influences (perceived parenting, alcohol abuse/dependence of parents, antisocial personality disorder of the father) and peer‐group characteristics (peer rejection and membership in a deviant peer group). The evaluation methods applied included correlation analyses and testing of two hypothetical models using structural equation modeling. The correlation analyses revealed significant relationships between adolescent aggressive and delinquent behavioral problems and parental antisocial behavior; perceived parental rejection and low emotional warmth; adolescent novelty‐seeking, self‐esteem, peer rejection and peer deviance. The two empirical models, separately for aggressive and delinquent behavior problems, revealed direct relationships between paternal antisocial behavior, parental rejection, adolescent novelty seeking, peer deviance, peer rejection, and offspring aggression and delinquency. There were, however, two differences with respect to the relationships between peer rejection, peer deviance, aggression and delinquency. First, peer rejection was more strongly associated with aggressive behavior and only moderately linked to delinquency. Second, deviance in the peer‐group was found to be closely related with delinquency but only moderately with aggression. Our findings suggest that several pathways for aggressive and delinquent conduct problems are comparable while others were not. Regarding the findings of the empirical models, we conclude that only intervention measures that include parents, peers and individual adolescents may help decrease the incidence of aggressive and delinquent conduct problems.

Temperament profiles from infancy to middle childhood: development and associations with behavior problems

The authors applied I-States as Objects Analysis (ISOA), a recently proposed person-oriented analytic approach, to the study of temperament development in 921 Norwegian children from a population-based sample. A 5-profile classification based on cluster analysis of standardized mother reports of activity, sociability, emotionality, and shyness at ages 18 months, 30 months, 4-5 years, and 8-9 years was interpretable and highly replicable. The prevalence of temperament profiles changed markedly with age, and individual stability in temperament profiles was significant. Specific typical and atypical developmental sequences of profiles were identified. Selective patterns of concurrent group differences in externalizing and internalizing problems by temperament profiles were remarkably similar across ages. The findings to some degree support the notion that individual temperament-variable values take on meaning in relation to the whole individual configuration and indicate some lawfulness in temperament changes over time. Future person-oriented studies of temperament development should replicate the current results using multiple data sources, rigorous tests of gender differences, and latent group modeling.

A randomized control trial to investigate the impact of the Lidcombe Program on early stuttering in German-speaking preschoolers

In order to investigate whether the Lidcombe Program effects a short-term reduction of stuttered speech beyond natural recovery, 46 German preschool children were randomly assigned to a wait-contrast group or to an experimental group which received the Lidcombe Program for 16 weeks. The children were between 3;0 and 5;11 years old, their and both of their parents’ native language was German, stuttering onset had been at least 6 months before, and their stuttering frequency was higher than 3% stuttered syllables. Spontaneous speech samples were recorded at home and in the clinic prior to treatment and after 4 months. Compared to the wait-contrast group, the treatment group showed a significantly higher decrease in stuttered syllables in home-measurements (6.9%SS vs. 1.6%SS) and clinic-measurements (6.8%SS vs. 3.6%SS), and the same increase in articulation rate. The program is considered an enrichment of currently applied early stuttering interventions in Germany.

Educational objectives: Readers will discuss and evaluate: (1) the short-term effects of the Lidcombe Program in comparison to natural recovery on stuttering; (2) the impact of the Lidcombe Program on early stuttering in German-speaking preschool children.     

Somatische und psychische Komorbidität

Studies indicate that chronic somatic diseases are often associated with psychological burden and manifest mental disorders. The interaction may be a complex one rather than a mere reaction to severe somatic illness. Early recognition of psychosomatic comorbidities has important implications for adequate diagnostic classification, therapy, and the course of the whole disease pattern. The timely treatment of depression in somatic illnesses can for example not only alleviate depressive symptoms but also raise quality of life and reduce the consequences concerning the course of the somatic disease. However, many questions still need to be answered relating to the concrete influence of a therapy of the mental disorder on the somatic prognosis.     

Lasting false beliefs and their behavioral consequences

False beliefs and memories can affect people's attitudes, at least in the short term. But can they produce real changes in behavior? This study explored whether falsely suggesting to subjects that they had experienced a food-related event in their childhood would lead to a change in their behavior shortly after the suggestion and up to 4 months later. We falsely suggested to 180 subjects that, as children, they had gotten ill after eating egg salad. Results showed that, after this manipulation, a significant minority of subjects came to believe they had experienced this childhood event even though they had initially denied having experienced it. This newfound autobiographical belief was accompanied by the intent to avoid egg salad, and also by significantly reduced consumption of egg-salad sandwiches, both immediately and 4 months after the false suggestion. The false suggestion of a childhood event can lead to persistent false beliefs that have lasting behavioral consequences.     

Linking thought suppression and recovered memories of childhood sexual abuse

There are two types of recovered memories: those that gradually return in recovered memory therapy and those that are spontaneously recovered outside the context of therapy. In the current study, we employed a thought suppression paradigm, with autobiographical experiences as target thoughts, to test whether individuals reporting spontaneously recovered memories of childhood sexual abuse (CSA) are more adept at suppressing positive and anxious autobiographical thoughts, relative to individuals reporting CSA memories recovered in therapy, relative to individuals with continuous abuse memories, and relative to controls reporting no history of abuse. Results showed that people reporting spontaneously recovered memories are superior in suppressing anxious autobiographical thoughts, both in the short term and long term (7 days). Our findings may partly explain why people with spontaneous CSA memories have the subjective impression that they have "repressed" their CSA memories for many years.     

Therapeutisches Gruppenprogramm für Stalking-Opfer

Stalking victims show a high level of psychological disturbance and frequently need professional help. Thus, stalking must be considered as a serious issue in the field of psychosocial care. However, specific intervention programs to support stalking victims are not available. This paper reports on a pilot project that offers therapeutic help to stalking victims via a structured outpatient group therapy approach. The program aims at setting up appropriate behavior patterns concerning contact with the stalker, strengthening the victims’ self-efficacy and developing coping strategies for stalking-related stress situations. To investigate the effectiveness of the group program, an evaluation study has been conducted using self-report inventories, interview data and biological parameters. Preliminary results from 4 completed groups with 13 participants, indicating that the approach is highly effective, are reported. The potential of the group approach to improve psychosocial care provision for stalking victims is discussed. The need to integrate psychotherapeutic approaches into a multi-professional support system for stalking victims, comprising legal counsel, police measures and psychosocial interventions, is emphasized.     

No Retrieval-Induced Forgetting Under Stress

ABSTRACT— Stress affects memory, yet no study has investigated the effects of stress on memory inhibition: Remembering not only facilitates later recall, but also inhibits retrieval of related material, a phenomenon known as retrieval-induced forgetting. We investigated the effects of stress on this mechanism, which is thought to adaptively guide memory selection. Participants learned categorized lists and were then exposed to either a psychosocial laboratory stressor or a cognitively challenging control treatment. They then actively retrieved parts of the previously learned material. Finally, memory for all initially learned items was tested. In the stress group, unlike in the control group, intervening retrieval practice did not impair final recall. Moreover, salivary cortisol levels increased and psychological well-being decreased in the stress group only. Thus, psychosocial stress abolishes retrieval-induced forgetting. This effect may result from stress-induced hormone release from the hypothalamic-pituitary-adrenal (HPA) axis and may have implications for educational, legal, and clinical issues.
