Treatment of covert food stealing in an individual with Prader-Willi syndrome

Covert food stealing is common among individuals with Prader-Willi syndrome. We found that verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decrease the food stealing of a girl with Prader-Willi syndrome. Warning stimuli were then used to help her discriminate between permitted and prohibited foods during sessions in which food stealing was not directly observed. This procedure resulted in decreases in food stealing from containers labeled with the warning stimuli.     

Determinants of stress-related growth: Gender,stressfulness of the event,and coping strategies

The present study aimed to investigate the determinants of stress-related growth. For this aim the associations of gender, stressfulness of the event, and three coping strategies (problem-oriented, fatalistic, and helplessness) with stress-related growth were tested by multiple regression analysis. Participants were 132 undergraduate students. Results revealed that females reported higher levels of stress-related growth than males, and as expected, higher levels of the stressfulness of the event associated with more stress-related growth. Furthermore, frequent utilization of problem-oriented and fatalistic coping strategies was associated with higher stress-related growth. These findings were discussed in the light of relevant literature and culture-specific features. This work has been supported by the Turkish Academy of Sciences, in the framework of the Young Scientist Award Program (TG-TUBA-GEB>P/2002-l-l 1).     

Short report: correlates of functional disability with disease activity in elderly patients with rheumatoid arthritis

Rheumatoid arthritis (RA) prevalence increases with age and old people are special patient population. The recognition of functional disability related to RA could be challenging in elderly patients because aging itself and potential co-morbid disease may also cause functional disability. In this study, we aimed to look at the correlation between disease activity and functional disability in elderly RA patients. Elderly RA patients, ≥65 years old at their routine visits were included in the study. The composite ‘disease activity score’ in 28 joints (DAS-28) was used to determine disease activity groups. Health assessment questionnaire (HAQ) scores were calculated to describe the functional disability and compared across the disease activity groups. Two hundred and fifty-eight RA patients with the mean age of 71 ± 5 (65–90) and a total disease duration of 8.4 ± 8.5 (.5–50) years were recruited. The proportion of patients with high and moderate disease activity was 70%. HAQ scores were significantly correlated with disease activity (p < .05). Functional disability estimated by HAQ was correlated with disease activity in elderly patients with RA     

Psychometric properties of the Miranda Rights Comprehension Instruments with a juvenile justice sample

This article describes the psychometric properties of the Miranda Rights Comprehension Instruments, the revised version of Grisso's Miranda instruments. The original instruments demonstrated good reliability and validity in a normative sample. The revised instruments updated the content of the original instruments and were administered to a sample of 183 youth in pre- and postadjudication facilities. Analyses were conducted to establish the psychometric properties of the revised instruments and included similar analyses to those conducted by Grisso, as well as additional calculations (e.g., standard errors of measurement, intraclass correlation coefficients, Kappa coefficients). Results revealed sound psychometric properties, similar to those observed for the original instruments.     

Assessing the "evolving standards of decency:" perceptions of capital punishment for juveniles

This study examines whether public opinion parallels recent judicial and statutory changes limiting the applicability of capital sentences to offenders younger than 18 years old. Two hundred and thirty-five undergraduate students were administered a vignette of a capital case and asked to render a sentence of death or life in prison without parole. Results revealed that age of the defendant was not a significant predictor of sentence type; participants sentenced 16- and 17-year-old defendants similarly to 18- and 25-year-old defendants. Therefore, public opinion appears inconsistent with legal and legislative changes to abandon the practice of executing juveniles. Findings also suggested that perceived level of the defendant's responsibility and general opinion about capital sentences significantly predicted sentence type; perceptions of greater responsibility were associated with an increased likelihood of a death sentence. However, participants did not perceive differences in responsibility between juvenile and adult defendants. In addition, participants were more comfortable sentencing defendants to death compared with life in prison.     

On the relative contributions of positive reinforcement and escape extinction in the treatment of food refusal

We compared the effects of positive reinforcement alone, escape extinction alone, and positive reinforcement with escape extinction in the treatment of the food and fluid refusal of 4 children who had been diagnosed with a pediatric feeding disorder. Consumption did not increase when positive reinforcement was implemented alone. By contrast, consumption increased for all participants when escape extinction was implemented, independent of the presence or absence of positive reinforcement. However, the addition of positive reinforcement to escape extinction was associated with beneficial effects (e.g., greater decreases in negative vocalizations and inappropriate behavior) for some participants.     

AN EVALUATION OF TWO METHODS FOR INCREASING SELF-INITIATED VERBALIZATIONS IN AUTISTIC CHILDREN

Three children with autism and mental retardation were treated for deficits in self-initiated speech. A novel treatment package employing visual cue fading was compared with a graduated time-delay procedure previously shown to be effective for increasing self-initiated language. Both treatments included training multiple self-initiated verbalizations using multiple therapists and settings. Both treatments were efffective, with no differences in measures of acquisition of target phrases, maintenance of behavioral gains, acquisition with additional therapists and settings, and social validity.     

Analysis of response covariationamong multiple topographies of food refusal

This study examined the effects of sequentially introducing treatment across multiple topographies of food refusal. Treatment with nonremoval of the spoon produced an increase in food acceptance and a decrease in disruption, but expulsion of food increased. When expulsion was treated, packing of food increased. Finally, when packing was treated, all refusal behaviors remained low, and acceptance continued to occur at high and stable levels.     

Juvenile offenders' Miranda rights comprehension and self-reported likelihood of offering false confessions

This study examined whether age, IQ, and history of special education predicted Miranda rights comprehension and the self-reported tendency to falsely confess to a crime among 55 delinquent boys. The Miranda Rights Comprehension Instruments-II, a revised version of Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights, were developed for this study and are described in detail in this article. Results revealed that age, IQ, and special education were related to comprehension of Miranda rights. When Miranda comprehension, age, and IQ were simultaneously tested as predictor variables of the self-reported likelihood of false confessions, only age served as an independent predictor. Research and policy implications of this study are presented, and recommendations for use of the original and revised instruments are reviewed.
