Subtyping female adolescent psychiatric inpatients with features of eating disorders along dietary restraint and negative affect dimensions

Cluster-analytic studies of eating disorders in adult patients have yielded two subtypes (pure dietary and mixed dietary-negative affect). This study aimed to replicate the subtyping in female adolescent psychiatric inpatients with features of eating disorders. Cluster analyses of 137 patients with eating-disordered features revealed a dietary-negative affect subtype (43%) and a pure dietary subtype (57%). The dietary-negative affect subtype was characterized by greater likelihood of binge eating, greater eating-related psychopathology, and greater body image dissatisfaction. The two subtypes did not differ significantly in scores reflective of clinical syndromes (other than the significantly higher depressive affect in the negative affect subtype), but the dietary-negative affect subtype was characterized by greater personality disturbance and higher reported concerns in clinical areas, including suicidality and childhood abuse. The cluster analysis produced different results from an alternative approach to subtyping by vomiting. These findings provide further support for the reliability and validity of this subtyping scheme for eating pathology. Clinically, the findings suggest that the combination of dieting and negative affect signals a more disturbed variant of eating-disorder related psychopathology in female adolescent psychiatric inpatients.     

Negative Emotions and Alcohol Use Initiation in High-Risk Boys: The Moderating Effect of Good Inhibitory Control

Studies on the relation between negative affect and later alcohol use have provided mixed results. Because definitions of negative affect often include diverse emotions, researchers have begun to dismantle this higher-order construct in an attempt to explain these inconsistent findings. More recent evidence also indicates that good inhibitory control may moderate the relation between negative emotions and alcohol use. The current longitudinal investigation examined the independent relation between three components of negative affect (i.e., depressed mood, fear, and anger) and alcohol use initiation in a sample of aggressive boys. The moderating effect of good inhibitory control was also examined. Results indicated that increased anger and decreased fearfulness are associated with an increased risk for alcohol use initiation only for boys with moderate to low levels of inhibitory control. However, depressed mood predicted alcohol use initiation for boys with good inhibitory control. The potential implications for substance use prevention efforts are discussed.     

Dismissing-avoidant pattern of attachment and mimicry reactions at different levels of information processing

Individuals with a dismissing-avoidant pattern of attachment are assumed to repress anxiety-related signals, a disposition hypothesized to interfere with facial mimicry and emotional contagion. Further, they are assumed to have one internal working model associated with anxiety, operating out of awareness at early, automatic stages of information processing, and another positive model operating at later, cognitively controlled stages of processing. The main aim of the present investigation was to compare facial mimicry in dismissing-avoidant and non-dismissing subjects at different levels of information processing. Pictures of happy and angry faces were exposed to 61 subjects at three different exposure times (17, 56, and 2,350 ms) in order to elicit facial muscle reactions, first at automatic levels and then at a more controlled levels. Corrugator activity ("frowning muscles") represented negative emotions and zygomaticus activity ("smiling muscles") positive emotions. The dismissing-avoidant subjects scored significantly lower on emotional empathy than the non-dismissing subjects. At the automatic level the dismissing-avoidant subjects showed "normal" corrugator responses (negative emotions) upon exposure to angry faces. At the cognitively controlled level of processing (2,350 ms) a significant interaction effect was shown between Faces x Muscles x Attachment pattern. The dismissing-avoidant subjects showed no corrugator response and an increased zygomaticus response ("smiling reaction") to the angry face, whereas the non-dismissing subjects reacted with a significant mimicking reaction. The dismissing-avoidant subjects' tendency to "smiling" in response to the angry face at the controlled level (2,350 ms) may be interpreted as a repression of their earlier, automatically evoked (56 ms) negative emotional reaction.     

Affect consciousness or mentalization? A comparison of two concepts with regard to affect development and affect regulation

Affect consciousness refers to the ability to adequately perceive, reflect upon and express affect. The concept is used in clinical work with adults, but lacks an equivalent for children's experience of affect. This paper examines the developmental prerequisites for affect consciousness, as well as the concept's applicability to work with children. The main focus is on the development of affect regulation throughout the first 6 years of life. Special emphasis is put on the role of attachment and the unfolding of mentalization ability in this development. The role of play as an organizing factor for affective experience is discussed. Observation of play is highlighted as a strong indicator of affect consciousness in children.     

Trauma and defences: their roots in relationship. An overview

In this paper the differing psychodynamic models of defences are outlined and compared with an attachment theory perspective in which affect regulation plays a central role. Behavioural and intrapsychic distance regulation (defensive exclusion) are seen as the main strategies for affect regulation and are the manifestations of the habitual pattern of emotional regulation in the relationship between the child and the primary caregiver. A new perspective on unconscious fantasy is offered, in which fantasies are seen to be actively created as defensive narratives to protect the development of healthy narcissism and to become integrated into a person's internal working models. Archetypal defences are explored from a developmental perspective and some neurobiological issues relevant to defences are highlighted.     

Affect and peer context interactively impact adolescent substance use

Risk factors, such as emotional distress and peer substance involvement, are often tested as competing influences on adolescent substance use. However, the current study examined how affect (both positive and negative) and peers (both in terms of relationship quality and substance involvement) are interactive influences on adolescent substance use. A sample of 398 high school juniors and seniors completed surveys assessing each of these domains. Results of hierarchical regression analyses showed strong associations between an adolescent's and his or her best friend's substance use. Complex interactions supported the study hypothesis in that relations between affect and adolescent substance use were context dependent, with some peer contexts enhancing risk for substance use and others dampening this risk. Implications of these findings for interventions and preventions concerning adolescent substance use are discussed.     

Self-objectification and compliment type: Effects on negative mood

The effects of trait self-objectification and compliment type (Neutral/Character/Appearance) on women's negative mood was examined. One hundred and eighty-five undergraduate women participated in mock appearance evaluations and interviews before completing questionnaires. As in previous research, women high on trait self-objectification displayed substantially greater body shame and appearance anxiety than women low on trait self-objectification. Women high on trait self-objectification who received character or appearance compliments expressed less negative mood than those receiving neutral compliments. A supplementary study (N = 53) suggested that the effect of positive compliments may be due, in part, to the fact that the self-esteem of high trait self-objectified participants was largely contingent on others’ approval. Offering highly trait self-objectified women positive statements concerning either their characters or their appearance temporarily assuages negative mood.     

Hoarding and its relation to obsessive-compulsive disorder

Although hoarding is observed in some patients with obsessive-compulsive disorder (OCD), it has not been shown to share a specific relation with OCD. Across two studies, we found that (a) whereas the classic OCD symptoms of checking, rituals, and contamination intercorrelated consistently strongly with one another, hoarding related only moderately to both these OCD symptoms and to depression; (b) OCD patients were distinguished from both other patients and non-patients by classic OCD symptoms, but not by hoarding; and (c) whereas OCD symptoms showed consistent relations with Negative Affect, hoarding largely was uncorrelated with this dimension. These results do not support a specific OCD-hoarding relation but rather call into question the trend of considering it a specific symptom of OCD.     

The Influence of Positive Affect on Intrinsic and Extrinsic Motivation: Facilitating Enjoyment of Play,Responsible Work Behavior,and Self-Control

Two experiments demonstrated that positive affect fosters intrinsic motivation, as reflected by choice of activity in a free-choice situation and by rated amount of enjoyment of a novel and challenging task, but also promotes responsible work behavior in a situation where the work needs to be done. Where there was work that needed to be done, people in the positive-affect condition reduced their time on the enjoyable task, successfully completed the work task, but also spent time on the more enjoyable task. These results indicate that positive affect does foster intrinsic motivation, and enjoyment and performance of enjoyable tasks, but not at the cost of responsible work behavior on an uninteresting task that needs to be done. Implications for the relationship between positive affect and such aspects of self-regulation as forward-looking thinking and self-control are discussed.

Reactive aggression in boys with disruptive behavior disorders: behavior,physiology, and affect

This study examined responses to peer provocation in boys ages 9–13 years who met symptomatic criteria for ADHD-only, ODD/CD-only, comorbid ADHD/ODD/CD, or no diagnosis. Boys participated in a reaction-time game that included standardized verbal and behavioral provocation. Their behavioral, physiological, and affective responses to this task were measured. Results showed that groups did not differ following high levels of provocation because all boys behaved aggressively. However, following low provocation boys with comorbid ADHD/ODD/CD had higher levels of behavioral aggression, had greater heart rate acceleration, and were rated as angrier than all other boys. In addition, boys with comorbid ADHD/ODD/CD held a grudge longer than other children. Results suggest that boys with comorbid ADHD/ODD/CD are especially reactive to provocation from their peers.
