Beery-Buktenica Developmental Test of Visual-Motor Integration performance in children with traumatic brain injury and attention-deficit/hyperactivity disorder

Evaluation of visuoconstructional abilities is a common part of clinical neuropsychological assessment, and the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI; K. E. Beery & N. A. Beery, 2004) is often used for this purpose. However, few studies have examined its psychometric properties when used to assess children and adolescents with traumatic brain injury (TBI) or attention-deficit/hyperactivity disorder (ADHD), even though these are among the most common acquired and neurodevelopmental forms of brain dysfunction in children. This study examined the validity of VMI scores in 123 children with TBI and 65 with ADHD. The TBI and ADHD groups performed significantly worse than the standardization sample, obtaining VMI mean scores of 87.2 (SD = 13.7) and 93.5 (SD = 11.27). Previous research has noted decrements in visuoconstructional abilities in TBI but relative sparing in ADHD. To examine the criterion validity of VMI scores, the authors therefore compared these 2 groups. As anticipated, the TBI group performed significantly worse than the ADHD group, but receiver operator characteristic analysis indicated that VMI scores were poor at discriminating between groups. Nonetheless, convergent validity evidence supported interpretation of VMI scores as measuring perceptual organization in both groups. In particular, principal components analysis indicated that VMI total scores loaded with perceptual organization tests from the Wechsler Intelligence Scale for Children, 3rd ed. (WISC-III; D. Wechsler, 1997), and its highest correlation was with the WISC-III Perceptual Organization Index. Also, the VMI correlated significantly with the Grooved Pegboard test for the group with TBI. These findings suggest that VMI scores are sensitive to visuoconstructional and motor deficits in children with developmental and acquired brain dysfunction.     

Dreaming and hallucinations - continuity or discontinuity? Perspectives from dementia with Lewy bodies

Comparing the phenomenology, neurochemical pathology, and psychopharmacology of hallucinations and dreaming is limited by the available data. Evidence to date reveals no simple correspondence between the two states. Differences in the phenomenology of visual hallucinations and the visual component of dreams may reflect variations in visual context acting on the same underlying mechanism – the minimal visual input during dreaming contrasts with the more substantial perceived context in hallucinations. Variations in cholinergic, dopaminergic and serotonergic neurotransmitter function during sleep and during hallucinations in Lewy body dementias, together with relevant drug effects suggest that, on the whole, different, potentially opposite, changes characterise the two states. A similar analysis of other psychotic features in Lewy body dementia and other disorders suggests that, in contrast to hallucinations, there may be more convincing parallels between dreaming and delusional states.     

Domain-specific conflict adaptation without feature repetitions

An influential account of how cognitive control deals with conflicting sources of information holds that conflict is monitored by a module that automatically recruits attention to resolve the conflict. This leads to reduced effects of conflict on the subsequent trial, a phenomenon termed conflict adaptation. A prominent question is whether control processes are domain specific—that is, recruited only by the particular type of conflict they resolve. Previous studies that have examined this question used two-choice tasks in which feature repetition effects could be responsible for domain-specific adaptation effects. We report two experiments using four-choice (Experiment 1) and five-choice (Experiment 2) tasks that contain two types of irrelevant sources of potentially conflicting information: stimulus location (Simon conflict) and distractors (flanker conflict). In both experiments, we found within-type conflict adaptation for both types of conflict after eliminating trials on which stimulus features were repeated from one trial to the next. Across-type conflict adaptation, however, was not significant. Thus, conflict adaptation was due to domain-specific recruitment of cognitive control. Our results add converging evidence to the idea that multiple independent control processes are involved in reactive cognitive control, although whether control is always local remains to be determined.     

The Impact of Perceptions of Health Control and Coping Modes on Negative Affect Among Individuals with Spinal Cord Injuries

A wide range of demographic, medical, and personality and coping variables have been implicated as predictors of psychosocial outcomes following the onset of spinal cord injuries (SCI). The primary purpose of this study was to examine the role that perceptions of health control (internality, chance-determined, and other persons-determined) and coping strategies play in predicting respondents’ negative affect, namely, reactions of depression and anxiety [i.e., posttraumatic stress disorder (PTSD)], as outcomes of psychosocial adaptation to disability. A second purpose was to investigate the potential role that time since injury (TSI) plays in moderating the influence of coping on psychosocial outcomes related to SCI. Ninety five survivors of SCI participated in the study by completing a battery of self-report measures. Two sets of multiple regression analyses were employed to address the study’s goals. Findings indicated that after controlling the influence of gender, age, time since injury, and number of prior life traumas: (a) the use of disengagement coping successfully predicted both respondents’ levels of depression and PTSD; (b) none of the perceptions of control of one’s health significantly influenced psychosocial reactions to SCI, as indicated by depression and PTSD, although perceptions of chance control showed a moderate positive trend; and (c) time since injury did not moderate the relationships between coping and negative affect related to the onset of SCI. The implications of these findings to rehabilitation professionals are discussed.     

Napping promotes inter-session habituation to emotional stimuli

The effects of a daytime nap on inter-session habituation to aversive visual stimuli were investigated. Healthy young adult volunteers viewed repeated presentations of highly negative and emotionally neutral (but equally arousing) International Affective Picture System (IAPS) photographs during two afternoon sessions separated by 2.5h. Half of the photographs were shown at both sessions (Repeated Sets) and half differed between sessions (Novel Sets). For each stimulus presentation, evoked skin conductance response (SCR), heart-rate deceleration (HRD) and corrugator supercilii EMG response (EMG), were computed and range corrected using respective maximum session-1 responses. Following each presentation, subjects rated each photograph on dimensions of pleasantness and arousability. During the inter-session interval, Nap subjects had a 120-min polysomnographically monitored sleep opportunity, whereas Wake subjects watched a non-stimulating video. Nap and Wake subjects did not differ in their subjective ratings of photographs. However, for Repeated-Set photographs, Nap subjects demonstrated greater inter-session habituation in SCR and EMG but a trend toward lesser inter-session habituation in HRD. These group differences were absent for Novel-Set photographs. Group differences across all measures were greater for negative stimuli. Occurrence of SWS during the nap was associated with greater inter-session habituation of EMG whereas occurrence of REM was associated with lesser inter-session habituation of SCR to negative stimuli. Sleep may therefore promote emotional adjustment at the level of somatic responses. Physiological but not subjective inter-session habituation to aversive images was enhanced by a daytime nap.     

Psychometric properties of the five facet mindfulness questionnaire in depressed adults and development of a short form

In recent years, there has been a growing interest in therapies that include the learning of mindfulness skills. The 39-item Five Facet Mindfulness Questionnaire (FFMQ) has been developed as a reliable and valid comprehensive instrument for assessing different aspects of mindfulness in community and student samples. In this study, the psychometric properties of the Dutch FFMQ were assessed in a sample of 376 adults with clinically relevant symptoms of depression and anxiety. Construct validity was examined with confirmatory factor analyses and by relating the FFMQ to measures of psychological symptoms, well-being, experiential avoidance, and the personality factors neuroticism and openness to experience. In addition, a 24-item short form of the FFMQ (FFMQ-SF) was developed and assessed in the same sample and cross-validated in an independent sample of patients with fibromyalgia. Confirmatory factor analyses showed acceptable model fit for a correlated five-factor structure of the FFMQ and good model fit for the structure of the FFMQ-SF. The replicability of the five-factor structure of the FFMQ-SF was confirmed in the fibromyalgia sample. Both instruments proved highly sensitive to change. It is concluded that both the FFMQ and the FFMQ-SF are reliable and valid instruments for use in adults with clinically relevant symptoms of depression and anxiety.     

The impact of mental health problems and religiosity on African-American girls' HIV-risk

We investigated the relationship between religiosity, mental health problems, and two sexual risk behaviors-condom use and number of partners. Participants were 80 sexually active African American girls in psychiatric care and their caregivers. Results indicated differential relationships, depending on parent versus youth report. Mother's religiosity was positively related to girls' condom use and not to girls' number of partners. Controlling for other predictors in the models, mother's religiosity explained as much as 15% of the variance in girls' condom use. Whereas parent and adolescent reports of girls' depression/anxiety and rule-breaking were positively associated with number of partners, reports of aggression were associated with having fewer partners. Neither parent nor youth reports of girls' mental health problems were associated with condom use. Controlling for other predictors in the models, girls' mental health problems accounted for as much as 31% of the variance in number of partners. Findings underscore the importance of adopting an ecological framework to understand both the risk and promotive factors for sexual risk taking among troubled girls. The roles of specific aspects of psychopathology and religiosity in relation to sexual risk behavior among African American girls in psychiatric care are discussed.     

Feasibility of telephone-based cognitive behavioral therapy targeting major depression among urban dwelling African-American people with co-occurring HIV

Given the burden of depression among those with HIV, and the impact of HIV on urban minority communities there is an urgent need to assess innovative treatment interventions that not only treat depression but do so in a way that allows for increased access to mental health care. This single site, uncontrolled, pilot study sought to determine the feasibility and depression outcomes of an 11-session telephone-based cognitive behavioral therapy intervention delivered over 14 weeks targeting low-income, urban-dwelling, HIV-infected African-American people with major depression. The diagnosis of major depression was made using the Mini International Neuropsychiatric Interview. The primary outcome was the Hamilton Depression Rating Scale (HAM-D) and the secondary outcome was the Quick Inventory of Depression Symptomatology-Self Report (QIDS-SR). Feasibility and satisfaction were also assessed. Assessments occurred at baseline, midpoint and at study conclusion (14 weeks). Fifteen people were screened for the study. Six HIV-infected, low-income, African-American people individuals (five females and one male) were eligible and participated in the study. All patients finished the study. On average, participants completed nine sessions. The sessions lasted for an average of 48 min (SD = 11.5). Compared to mean HAM-D score at baseline (HAM-D = 22.8 (SD = 3.1), the mean HAM-D score was significantly reduced at study conclusion (HAM-D = 9.8 (SD = 7.4); (t (5) = 4.6, p = 0.006); (Cohen d = 1.9)). Compared to the mean QIDS-SR score at baseline (QIDS-SR = 15.5 (SD = 4.2) the mean QIDS score was significantly reduced at study conclusion (QIDS = 7.0 (SD = 5.4);(t (5) = 3.2, p = 0.02); (Cohen d = 1.3)).The mean satisfaction scores across all participants at post-treatment was 5.7 (SD = 0.3) with of a maximum score of 6. Telephone-based CBT can be delivered to low-income, urban-dwelling ethnic minority HIV-infected people resulting in significant reductions in depression symptoms with high satisfaction. The efficacy of this intervention will be assessed in a planned randomized control trial.
