Angstzustände bei Patienten mit schweren Persönlichkeitsstörungen

States of anxiety are very common problems in patients with severe personality disorders. All phenomena of anxiety can be observed. In this connection a continuum of the severity of impairment of structural personality organisation can be postulated. In many cases proper anxiety disorders exist as comorbid disorders. Anxiety is esteemed to be the central affective problem of borderline patients. In spite of these relations, states of anxiety in patients with personality disorders are often underdiagnosed or misdiagnosed. For the treatment of neurotic anxiety disorders (for example panic disorders), there exist disorder-specific therapy manuals that proceed from behavioural as well as psychodynamic perspectives. Nevertheless, for the treatment of anxiety states in personality disordered patients, the techniques that focus heavily on symptomatology appear often contraindicated. In our opinion, treatment of these typically severe anxieties must be contained within a therapeutic framework, which essentially takes into account the personality organisation of this group of patients. Such treatment makes special demands on the therapist for working with transference and countertransference processes. From a disorder-specific psychodynamic perspective recommendations are given for psychotherapy.     

Mentoring support and power: A three year predictive field study on protégé networking and career success

Career success of early employees was analyzed from a power perspective and a developmental network perspective. In a predictive field study with 112 employees mentoring support and mentors’ power were assessed in the first wave, employees’ networking was assessed after two years, and career success (i.e. income and hierarchical position) and career satisfaction were assessed after three years. Networking was the most robust predictor of career success. Mentoring received predicted career satisfaction and its effects on objective career success were mediated by networking. Further, mentoring by a powerful mentor predicted objective career success beyond networking. Based on previous findings we argue that these findings underscore the critical relationship between early career employees’ networking behaviors and mentoring received.     

Emotional states preceding and following acts of non-suicidal self-injury in bulimia nervosa patients

Bulimia nervosa and non-suicidal self-injury (NSSI) co-occur at high rates, and both have been conceptualized as maladaptive emotion regulation strategies. Treatments focusing on emotion regulation have been designed for both problem behaviors, yet, there exists very little research examining the temporal emotional states surrounding acts of NSSI. Using ecological momentary assessment (EMA) methodology, the current study examined the temporal association between positive and negative emotional states prior to and consequent to acts of NSSI within a subset of bulimia nervosa patients. Results indicate significant increases in negative affect, and decreases in positive affect, prior to an NSSI act. Post-NSSI, positive affect significantly increased while negative affect remained unchanged. The findings offer partial support for an emotion regulation paradigm to understanding NSSI within bulimic populations and implications for treatment are discussed.     

Long-term outcome of Internet-delivered cognitive-behavioural therapy for social phobia: A 30-month follow-up

Internet-delivered guided cognitive behaviour therapy for social anxiety disorder has been found to generate promising short-term results, up to one year posttreatment. No study has however documented longer follow-up periods. In this 30-month follow-up we contacted 57 participants from the original study of which 77.2% (44/57) responded to the Internet-administered outcome measures and 66.7% (38/57) completed a telephone interview. Results showed large pretreatment to follow-up within-group effect sizes for the primary outcome measures (Cohen's d 1.10-1.71), and a majority (68.4%; 26/38) reported improvements in the interview. The findings suggest that the long-term effects seen in previous live treatment CBT trials can occur in Internet-delivered treatment as well.     

Mental representation of length and weight series and transitive inferences in young children

Forty-eight second graders (8 years of age) were trained on length or weight relationships between adjacent members of a five-term series of colored objects. Feedback was visual and of either minimal or strong salience. Differences in weight were assessed by either a balance scale or a spring scale. Results showed that more salient visual feedback reduced the learning effort for length but not for weight comparisons. After training children were tested on all possible object pairs. Children's comparisons of items by length were very accurate in contrast to their comparisons by weight. An explanation for these findings is suggested by the data from a group of 6-year-olds who were trained on two independent pairs of a four-term series. Test results showed that subjects spontaneously encoded absolute lengths but tended to ignore information about the absolute weight of objects. It is suggested that high test accuracy depends on stimulus material for which the absolute values of the relevant dimension are encoded. The implications for taking test performance as an indicator of “transitive reasoning” ability are discussed.     

Mixtures of conditional mean- and covariance-structure models

Models and parameters of finite mixtures of multivariate normal densities conditional on regressor variables are specified and estimated. We consider mixtures of multivariate normals where the expected value for each component depends on possibly nonnormal regressor variables. The expected values and covariance matrices of the mixture components are parameterized using conditional mean- and covariance-structures. We discuss the construction of the likelihood function, estimation of the mixture model with regressors using three different EM algorithms, estimation of the asymptotic covariance matrix of parameters and testing for the number of mixture components. In addition to simulation studies, data on food preferences are analyzed.The authors are grateful to Donald B. Rubin and Michael E.
