Anxiety Symptoms as Predictors of Nursing Home Placement in Patients with Alzheimer's Disease

Anxiety symptoms are fairly common among patients with Alzheimer's Disease (AD). Such symptoms are likely to make patient care more problematic and, therefore, increase the risk of nursing home placement. Anxiety symptoms were evaluated on the basis of physician examinations, in conjunction with caregiver interviews, in 372 community-dwelling AD patients. Patients received annual follow-up for 1–12 years (M = 4.4). Patients who exhibited anxiety symptoms at baseline assessment were significantly more likely to enter nursing homes, regardless of initial cognitive status or other risks for institutionalization. There was a 15% increase in risk for each point on a 0–5 scale. This study supports the hypothesis that anxiety symptoms increase the risk of nursing home placement in patients with AD. Consequently, there is a need for better understanding of the causes of anxiety in AD and for the development of effective methods of assessment and treatment.     

Frontal brain asymmetry in restrained eaters

It is well known that the eating patterns that restrain chronic dieters (restrained eaters) can be disinhibited by anxiety, which in turn has been associated with relative right frontal brain activity in independent electroencephalographic (EEG) studies. Combining these two lines of evidence, the authors tested the hypothesis that chronic restrained eating is associated with relative right frontal asymmetry. Resting anterior brain asymmetry and self-reported measures of anxiety and depression were collected in 23 restrained and 32 unrestrained eaters. As hypothesized, groups differed in tonic frontal activity, with restrained eaters showing more relative right frontal activity. Furthermore, relative right frontal activity was associated with greater self-reported restraint. Right-sided prefrontal asymmetry may thus represent a diathesis associated with increased vulnerability toward restrained eating.     

Gender, neuroticism and speed-accuracy tradeoffs on a choice reaction-time task

The Eysenck Personality Questionnaire and Personality Inventory were administered to 96 college students, along with a choice reaction-time (RT)/movement-time task. The results show that females and Ss high on neuroticism made significantly fewer ballistic errors on the RT. The implications for RT research are discussed.     

Visual capture and human error

We investigated relationships between everyday error rates, susceptibility to stimulus‐driven (i.e. external) capture of visual attention and working memory. Using an eye‐tracking task called the antisaccade paradigm, we found that relatively error‐prone subjects made significantly more unintended, stimulus‐driven eye movements. This finding suggests a link between error‐proneness and a tendency towards environmental (versus volitional) control of behaviour. No evidence was found for a connection between working memory capacity and error proneness or eye movements, though range restriction may have affected the working memory results. The findings are compatible with the view that some mishaps stem from environmental capture and triggering of inappropriate actions, and that individuals vary in their susceptibility to capture. Some implications are that: (1) mishaps might be reduced by redesigning tasks to reduce capture errors, e.g. by restructuring critical tasks to eliminate action sequences with common initial stages; (2) the antisaccade task may be a useful dependent measure in research on how stressors (e.g. fatigue, noise, temperature) increase the likelihood of mishaps. Specifically, since antisaccade performance was correlated with reports of real‐world mistakes in the current study, antisaccade scores may allow useful predictions about how accident probability varies as a function of different conditions.

How U.S. Children and Adolescents Spend Time: What It Does (and Doesn't) Tell Us About Their Development

Young people develop as "the sum of past experiences," and data on their time use are one means of quantifying those experiences. U.S. children and adolescents spend dramatically less time than in the agrarian past in household and income-generating labor. Because such labor is usually repetitive and unchallenging, this reduction has probably not deprived youths of crucial developmental experience. The schoolwork replacing this time has a clearer relationship to developmental outcomes. American teens, however, spend less time on schoolwork than teens in other industrialized countries. American teenagers have more discretionary time, much spent watching television or interacting with friends; spending large amounts of time in these activities is related to negative developmental outcomes. Increasing amounts of young people's discretionary time, however, appear to be spent in structured voluntary activities, like arts, sports, and organizations, which may foster initiative, identity, and other positive developmental outcomes.     

Teaching social‐learning procedures to paraprofessionals working with individuals with severe mental illness in a maximum‐security forensic hospital

This study describes an integrated technical method for teaching learning‐based interventions to paraprofessionals working in a maximum‐security psychiatric facility as a social‐learning program was implemented. This training approach combines brief didactic instruction with live demonstration and guided practice in specific procedures. Comparisons between baseline and post‐training functioning of staff were made using ongoing direct observational assessment data. Results revealed that following training and program implementation staff were much more active overall, interacted with clients far more often, and engaged in much lower rates of job‐irrelevant activity. Moreover, following training direct observational data of the patterns of staff–client interactions showed that staff were much more likely to demonstrate interactions reflective of learning‐based interventions than at baseline. These results have important implications for clinicians and administrators attempting to implement behavioral rehabilitation programs. Copyright © 2001 John Wiley & Sons, Ltd.     

Religious involvement and mortality: a meta-analytic review.

A meta-analysis of data from 42 independent samples examining the association of a measure of religious involvement and all-cause mortality is reported. Religious involvement was significantly associated with lower mortality (odds ratio = 1.29; 95% confidence interval: 1.20-1.39), indicating that people high in religious involvement were more likely to be alive at follow-up than people lower in religious involvement. Although the strength of the religious involvement-mortality association varied as a function of several moderator variables, the association of religious involvement and mortality was robust and on the order of magnitude that has come to be expected for psychosocial factors. Conclusions did not appear to be due to publication bias.
