Parent vs. Self-Report: Contributions Toward Diagnosis of Adolescent Psychopathology

Assessment of psychopathology in adolescents can be complicated due to uncertainties about who should be considered the primary informant. While a multimethod, multiinformant approach to assessment allows for a thorough assessment, it can also result in contradictory findings. The purpose of this study was to use a sample of 121 adolescents to investigate issues of parent-adolescent agreement on behavior rating scales and a structured diagnostic interview. Additionally, this study evaluated whether adolescent report offers unique information to the assessment beyond the parent's report. The sample included both normal controls and adolescents who met criteria for diagnosis of an Internalizing or Externalizing disorder based on the DSM-IV criteria. Agreement between parents and adolescents on the Diagnostic Interview for Children and Adolescents—Revised (DICA-R) was low for ADHD (39.4%) and Externalizing Disorders (41.1%) and moderate for Internalizing Disorders (56.6%). A significant difference was found between the number of ADHD symptoms reported, with parents reporting more symptoms (M = 9.42) than adolescents (M = 8.34). Regression analysis indicated that the adolescent completed Youth Self-report (YSR) contributed unique information beyond the parent completed measures in predicting both the adolescent and the parent interviews for Internalizing Disorders. This finding emphasizes the need to continue to collect self-report information, especially when assessing Internalizing disorders, which inherently contain symptoms indicating high-risk behaviors such as suicide ideation.     

Selective peripheral fading: evidence for inhibitory sensory effect of attention

A circular array of six discs, three green and three orange in alternate positions, was presented against a uniform grey background. Sixteen observers maintained steady fixation at the centre of the array, and were instructed to direct their attention to three discs of one colour and to ignore the three discs of the other colour. In about 10 s (mean = 11.35 s), some discs started to fade away from awareness. Of those starting to fade, most (mean = 81.3%) were those selected for attention. The faded discs remained out of awareness for up to a few seconds (mean = 1.55 s) during which other discs were clearly visible. The fading increased with eccentricity, a defining characteristic of Troxler fading. However, the selectivity of the fading strongly suggests that voluntary attention can have an inhibitory effect on early sensory processing. Were the fading entirely due to local sensory adaptation, the unattended stimuli would have to be equally adapted and yet somehow remain visible for seconds, which is not plausible.     

Manualized Treatment of Panic Disorder in a Medical Setting: Two Illustrative Case Studies

People who experience panic attacks (PAs) typically present to medical settings, concerned that their symptoms signify a life-threatening condition. Despite the efficacy of cognitive-behavioral therapy (CBT) for panic disorder (PD), medical practitioners seldom provide this type of treatment. Physicians may lack the time or expertise to impart such behavioral medicine interventions, while patients may find group or individual CBT too costly even when available. Researchers have begun investigating manualized CBT as a cost-effective alternative when traditional forms of this intervention are prohibited. This article describes two case studies in which women presenting to a medical clinic with PD were treated with 6 weeks of manualized CBT after pharmacotherapy was unsuccessful or unpalatable. Both patients exhibited reductions in panic and depressive symptomatology over baseline levels, along with increases in self-efficacy regarding their ability to manage future PAs. Improvements were maintained over 12 months, supporting continued use of manualized CBT as a supplement or alternative to pharmacological methods of treating PD in the medical setting.     

Primary and secondary reinforcers as distinctive cues which acquire information value in partial-reinforcement discrimination training

To assess the cue as opposed to incentive effect of reward, rats were trained on an easy visual discrimination with food contingent on 50 or 100% of the correct responses, and white-noise contingent on 0, 50 or 100% of these responses. Additionally, the 50% food and noise schedules were structured for different groups to produce positive, zero, or negative correlations of the two events. Although the addition of noise did not affect learning with 100% food, the slower learning observed with 50% food was increasingly offset by greater percentages of noise, with the 50% groups showing faster learning under the negative than zero correlation and faster under the zero than positive correlation. Together with supporting speed data, these results indicate that a “neutral” stimulus can be substituted for food with little loss in performance. Consequently, the reinforcing effect of food is attributed in part to its function as a cue which, like noise, can increase the discriminability of the alternatives and provide information about the correctness of the response.

Residual effects of lead poisoning on denver Developmental Screening Test scores

Subtest and Total scores on the Denver Developmental Screening Test were examined for a group of 22 preschool- aged low-income children who had been lead-poisoned, then medically deleaded. Pretest scores were obtained before blood lead elevations occurred;posttest scores were obtained an average of 4.5 months after deleading. Pretest scores were comparable to those of a matched Control group, but posttest scores on the Fine Motor-Adaptive subtest declined, indicating significant residual effects of lead poisoning.The authors wish to acknowledge the support of Shirley Nelson of the Tulane University School of Social Work, and Catherine Kitchens and Percy Rosenbaum of the Lead Poisoning Prevention Program of the New Orleans Health Department.     

Psychometric properties of the Social Problem Solving Inventory (SPSI) with normal and emotionally disturbed adolescents

The factor structure of the Social Problem Solving Inventory (SPSI; D'Zurilla & Nezu, 1990) was evaluated with a sample of 708 normal adolescents. Confirmatory factor analysis supported the empirically derived five-factor model reported by D'Zurilla and Maydeu-Olivares (1994) using an adult sample, but not the theoretically derived seven-factor structure of the original SPSI. The psychometric properties of the original and revised inventories are reported for normal adolescents and psychiatrically hospitalized adolescents (n=63). Internal consistency and reliability estimates were adequate. Support for the validity of the revised SPSI was demonstrated by examining the relationship between social skills, depression, and social problem solving; in addition, differences between normal and inpatient adolescent samples were examined. The findings are discussed in terms of the utility of the inventories with adolescents.     

Air pollution, cognitive deficits and brain abnormalities: a pilot study with children and dogs

Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance imaging MRI. Seven healthy young dogs with similar exposure to Mexico City air pollution had brain MRI, measurement of mRNA abundance of two inflammatory genes cyclooxygenase-2, and interleukin 1 beta in target brain areas, and histopathological evaluation of brain tissue. Children with no known risk factors for neurological or cognitive disorders residing in a polluted urban environment exhibited significant deficits in a combination of fluid and crystallized cognition tasks. Fifty-six percent of Mexico City children tested showed prefrontal white matter hyperintense lesions and similar lesions were observed in dogs (57%). Exposed dogs had frontal lesions with vascular subcortical pathology associated with neuroinflammation, enlarged Virchow-Robin spaces, gliosis, and ultrafine particulate matter deposition. Based on the MRI findings, the prefrontal cortex was a target anatomical region in Mexico City children and its damage could have contributed to their cognitive dysfunction. The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children.     

Incorporating family therapy into asthma group intervention: a randomized waitlist-controlled trial

Asthma psychoeducational programs have been found to be effective in terms of symptom-related outcome. They are mostly illness-focused, and pay minimal attention to systemic/familial factors. This study evaluated a novel asthma psychoeducation program that adopted a parallel group design and incorporated family therapy. A randomized waitlist-controlled crossover clinical trial design was adopted. Children with stable asthma and their parents were recruited from a pediatric chest clinic. Outcome measures included, for the patients: exhaled nitric oxide (eNO), spirometry, and adjustment to asthma; and for the parents: perceived efficacy in asthma management, Hospital Anxiety and Depression Scale anxiety subscale, Body Mind Spirit Well-being Inventory emotion subscale, and Short Form 12 health-related quality of life scale. Forty-six patients participated in the study. Attrition rates were 13.0% and 26.0% for the active and control groups, respectively. Repeated-measures ANOVA revealed a significant decrease in airway inflammation, as indicated by eNO levels, and an increase in patient's adjustment to asthma and parents' perceived efficacy in asthma management. Serial trend analysis revealed that most psychosocial measures continued to progress steadily after intervention. Significant improvements in both symptom-related measures and mental health and relationship measures were observed. The findings supported the value of incorporating family therapy into asthma psychoeducation programs.
