Cultural differences in the relationship between parenting and children's behavior

Parent and teacher data for 14,990 children from the National Longitudinal Survey of Children and Youth were used in multilevel analyses to examine the relationship between ethnicity, children's aggression and emotional problems, and parenting. Using parent and teacher report, relationships between ethnicity and child behavior were present but modest. The association between parental harshness and child aggression differed between ethnic groups and across informants. Using teacher report of outcomes, parental harshness was positively related to child aggression in European Canadian families but negatively related in South Asian Canadian families. For all ethnic groups, parental harshness was positively related to children's aggression when parent report of outcomes was used, but relationships varied in strength across ethnic groups. The relationship of parental harshness with child emotional problems did not differ across groups, irrespective of informant. The results are discussed within the context of an ecological model of parenting.     

The relationship between short‐term memory and working memory: Complex span made simple?

This experiment addresses the question of what makes a working memory measure a good predictor of higher‐level abilities. Verbal and visuospatial processing episodes were interleaved with distinct verbal and visuospatial storage episodes to form four complex span tasks. Although these measures were reliable predictors of reading and mathematics ability in children, they were no more predictive of these abilities than corresponding simple span tasks involving storage alone. However, when individual differences in storage ability and processing capacity were controlled for, residual variance in complex span performance was related to academic ability in some cases. These findings indicate that complex span tasks are multiply determined, and that differences in task structure can dramatically influence the relative importance of these multiple constraints and the predictive power of a complex span measure.     

Testing improves true recall and protects against the build-up of proactive interference without increasing false recall

Retrieval practice has been shown to protect against the negative effects of previously learned information on the learning of subsequent information, while increasing retention of new information. We report three experiments investigating the impact of retrieval practice on false recall in a multiple list paradigm. In three different experimental designs participants studied blocks of interrelated words that converged on non-presented associates. Participants were tested either after every study block or only after the fifth study block, and both groups received a cumulative test on all five study blocks. Overall the results from all three different experimental designs point to a benefit of testing in increasing long-term veridical recall on the cumulative test. More importantly, this improvement in veridical recall did not come at a cost: False recall on the cumulative test did not increase from retrieval practice.     

Changes in health status after one year for persons at-risk for and with HIV infection

Abstract

Health status is an important component of the evaluation of patient outcome in HIV infection where disease is chronic, progressive, and debilitating. This paper compares patient self-report for 9 dimensions of health status for patients followed in ATHOS (AIDS Time-Oriented Health Outcome Study). We compared changes in functioning after 12 months for 1, 524 patients with varying HIV disease severity: 238 asymptomatic, 447 symptomatic, 441 AIDS, and 398 HIV-negative individuals who are at-risk for infection.

Declines in health status were observed for all HIV-infected persons, including also asymptomatic patients. Individuals with symptomatic disease or AIDS had significant declines (p < 0.001) in physical functioning, energy, global health, pain, and increased disease symptoms, but no significant declines in health distress, cognition, or mental health. Persons with AIDS had greater declines than those with symptomatic disease. All HIV-infected individuals reported significantly fewer hours at work and more disability days than HIV-negative patients from similar risk pools. The adverse impact that HIV infection has on the health status of HIV-positive asymptomatic individuals is striking; HIV-negative individuals are more similar to HIV-positive individuals than to the general population.     

The use of diabetes-specific perceived control and health belief measures to predict treatment choice and efficacy in a feasibility study of continuous subcutaneous insulin infusion pumps

Abstract

In the course of a feasibility study of continuous subcutaneous insulin infusion pumps, 382 insulin-requiring diabetic patients were offered a choice of CSII, intensified conventional treatment or conventional treatment. Two hundred and eighty-six (75%) patients completed newly developed diabetes-specific measures of health beliefs and attributions before any change of treatment regimen. The scales were useful predictors of patients' choice of treatment. Furthermore, they were useful in predicting efficacy of treatment in terms of glycosylated haemoglobin measures of diabetes control after one year of treatment in the study. The implications of the findings for introducing patients to new forms of treatment are discussed.     

Sleep Disturbances Among Combat Military Veterans: A Comparative Study Using Subjective and Objective Sleep Assessments

The sleep characteristics of 37 military veterans and active-duty service members (17 with PTSD and 20 without PTSD) of recent wars were analyzed to determine if combat deployment, with its associated sleep restriction, may be an alternative explanation for the sleep complaints found among combat veterans with PTSD (as determined by PTSD Checklist Military Version scores). Over a 1-week period, sleep data were collected using sleep actigraphy and self-report. Across the entire sample, subjective and objective assessment methods of sleep were strongly correlated, although there were some notable within-group differences. Specifically, although sleep duration between groups did not differ based on actigraphy, veterans without PTSD reported sleeping 1 h and 11 min (p = .002) longer than did veterans with PTSD. In an effort to determine why individuals without PTSD might be overreporting sleep, we found that symptoms of emotional arousal (anger, anxiety, and nightmares) were significantly correlated with self-reported sleep duration, suggesting a pattern of higher autonomic arousal found in veterans with PTSD. Thus, although sleeping for 6 h, the higher levels of emotional arousal reported by veterans with PTSD may mean that they do not perceive their sleep as restful. Further research is necessary to determine if the sleep architecture of veterans with PTSD is actually different from that of combat veterans without PTSD and if such differences are actually amenable to standard behavioral treatments for this disorder.     

Memory for Faces in Children with Autism

Previous research has established that children with Autistic Disorder have deficits in aspects of social cognition and in verbal memory, but research on social memory is limited. Twenty-four autistic boys aged 7 to 12 years and normal controls matched for verbal mental age were administered parallel social and nonsocial matching and memory tasks. Results showed that the children with autism were impaired relative to the normal children on the social (face) memory task only. Furthermore, of the four experimental tasks, the social memory task had the highest and most consistent correlations with measures of social development and adaptive skills. Whereas the normal children used the special status of faces to recall them more easily than objects, the children with autism showed equal recall of objects and faces.
