ADHD Symptoms in Post-Institutionalized Children Are Partially Mediated by Altered Frontal EEG Asymmetry

Individual differences in the propensity for left versus right frontal electroencephalogram (EEG) asymmetry may underlie differences in approach/withdrawal tendencies and mental health deficits. Growing evidence suggests that early life adversity may shape brain development and contribute to the emergence of mental health problems. The present study examined frontal EEG asymmetry (FEA) following the transition to family care in children adopted internationally from institutional care settings between 15 and 36 months of age (N = 82; 46 female, 36 male). Two comparison groups were included: an international adoption control consisting of children adopted from foster care with little to no institutional deprivation (N = 45; 17 female, 28 male) and a post-adoption condition control consisting of children reared in birth families of the same education and income as the adoptive families (N = 48; 23 female, 25 male). Consistent with evidence of greater approach and impulsivity-related behavior problems in post-institutionalized (PI) children, PI status was associated with greater left FEA than found in the other two groups. In addition, left FEA served as a mediator between institutionalization and age 5 ADHD symptoms for girls. Age at adoption and other preadoption factors were examined with results suggesting that earlier adoption into a supportive family resulted in a more typical pattern of brain functioning. Findings support the idea that the capacity of brain activity to evidence typical functioning following perturbation may differ in relation to the timing of intervention and suggest that the earlier the intervention of adoption, the better.     

Ethical Considerations for Clinicians Treating Victims and Perpetrators of Intimate Partner Violence

Intimate partner violence (IPV), a subcategory of domestic abuse, is a prevalent national health concern that many clinicians will face during their careers. It is important that clinicians become aware of the numerous ethical considerations that are relevant to this population. The existing literature has not yet examined the ethical issues faced by clinicians working with IPV clients through the lens of the most recent American Psychological Association ethics code. This article provides a brief overview of the historical context and the current state of the literature pertaining to IPV. Then it examines the unique ethical challenges associated with the treatment of IPV clients through the American Psychological Association ethics code. Recommendations are provided throughout this article to help clinicians make ethical decisions, maximize the benefits their clients receive from therapy, and minimize violence risk.     

The measurement of impairment due to eating disorder psychopathology

Eating disorders have a profound and highly specific impact on psychosocial functioning. The aim of this research was to develop a measure of such secondary impairment. A 16-item, self-report instrument was developed, the Clinical Impairment Assessment (CIA), which was designed to measure such impairment overall and in three specific domains (personal, cognitive, social). The psychometric properties of the instrument were evaluated using data collected in the context of a transdiagnostic treatment trial. The findings consistently supported the utility of the instrument with the CIA being shown to have high levels of internal consistency, construct and discriminant validity, test-retest reliability, and sensitivity to change. The CIA should be of value to clinicians when assessing patients with eating disorders and their response to treatment. It should also help inform epidemiological research.     

Baseline measurement of running away among youth in foster care

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e., single-subject vs. grouped data). Seven different baseline measures were calculated for 84 runaways, and a unit-size analysis was conducted by constructing groups of various sizes from the original sample. An expert panel evaluated the suitability of the baseline measures for treatment evaluation. Results demonstrate the utility of evaluating duration-based measures and correcting for occurrence opportunity. Results also indicate that single-subject baselines may often be unacceptable for treatment evaluations, regardless of the type of measure selected for use.     

The worker scale: Developing a measure to explain gender differences in behavioral self-handicapping

Research has consistently found that men engage in more behavioral self-handicapping than do women. We first review evidence suggesting that these gender differences result from women placing more importance on displaying effort than do men. We then present the results of two studies seeking to develop measures of beliefs about effort that might explain these gender differences in behavioral self-handicapping. Women, across a wide range of measures, placed more importance on effort than did men. However, only a new measure of more personalized effort beliefs, dubbed the Worker scale, uniquely explained gender differences in dispositional tendency to behaviorally self-handicap. The Worker scale also predicted academic performance, consistent with the notion that these effort beliefs would predict engagement in actual behavioral self-handicaps that undermine performance.     

Young children's knowledge about the influence of thoughts on emotions in rule situations

Four‐year‐olds, 5‐year‐olds, and adults (N = 48) listened to stories featuring characters that experienced one of four types of thoughts after deciding to transgress or comply with a rule: thoughts about desires, rules, future negative outcomes, or future punishment. Participants predicted and explained the characters’ emotions. Results showed that young children, as with adults, predicted positive emotions for willpower and negative emotions for transgression at low rates for the think‐desire trials, and at high rates for the think‐rule and think‐future trials. They also modified their emotion explanations in line with the focus of characters’ thoughts. These data provide unprecedented evidence that young children can reason flexibly about emotions in rule situations when provided explicit, salient information about people's thoughts.     

Taboo,emotionally valenced,and emotionally neutral word norms

Although taboo words are used to study emotional memory and attention, no easily accessible normative data are available that compare taboo, emotionally valenced, and emotionally neutral words on the same scales. Frequency, inappropriateness, valence, arousal, and imageability ratings for taboo, emotionally valenced, and emotionally neutral words were made by 78 native-English-speaking college students from a large metropolitan university. The valenced set comprised both positive and negative words, and the emotionally neutral set comprised category-related and category-unrelated words. To account for influences of demand characteristics and personality factors on the ratings, frequency and inappropriateness measures were decomposed into raters’ personal reactions to the words versus raters’ perceptions of societal reactions to the words (personal use vs. familiarity and offensiveness vs. tabooness, respectively). Although all word sets were rated higher in familiarity and tabooness than in personal use and offensiveness, these differences were most pronounced for the taboo set. In terms of valence, the taboo set was most similar to the negative set, although it yielded higher arousal ratings than did either valenced set. Imageability for the taboo set was comparable to that of both valenced sets. The ratings of each word are presented for all participants as well as for single-sex groups. The inadequacies of the application of normative data to research that uses emotional words and the conceptualization of taboo words as a coherent category are discussed.

Cognitive processing of body and appearance words as a function of thin-ideal internalization and schematic activation

To better understand how women at risk of body image disturbance respond when their body concerns are activated, we examined attentional and memory biases in undergraduate women with high thin-ideal internalization, an identified risk factor for eating disorders, following priming of body and appearance concerns. Female undergraduates (N = 186) viewed photos of either sports cars or attractive swimsuit models, then completed the Lexical Decision Test, a word recall test, and questionnaires assessing thin-ideal internalization and eating disorder symptomatology. High thin-ideal internalizers did not exhibit cognitive biases predicted by cognitive models of eating disorders, even when their body and appearance concerns were primed by exposure to attractive models. Converging evidence suggests that high-risk non-clinical samples rarely exhibit cognitive biases characteristic of individuals with eating disorders, and, in fact, may actually incorporate ideal appearance into their schemas and preferentially attend to attractive stimuli.     

An investigation of the effects of dog visits on depression,mood, and social interaction in elderly individuals living in a nursing home

The present study investigated the effects of weekly dog visits on depression scores, mood, and social interaction in elderly individuals living in a nursing home. Five elderly residents participated in baseline assessments for 4–8 weeks and then received weekly dog visits for 6 weeks. Assessments, consisting of weekly observations of social interaction and paper and pencil measures of mood and depression, continued during the dog visits. The effect of dog visits was evaluated in a multiple baseline across participants design. Dog visits did not improve depression scores, mood (with the exception of one resident), or social interaction (with the exception of one resident). Residents did interact with the dog during the visits, however, and reported that they enjoyed the visits. These results show that dog visits do not always have therapeutic effects and suggest the need for further research in the area before the beneficial effects of dog visits can be substantiated.
