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.     

Faking psychopathy? An examination of response styles with antisocial youth

Psychopaths frequently con and manipulate others in an attempt to achieve their own objectives. In the current literature, correlational research has generally found that psychopathy has (a) an inverse relation with social desirability and (b) a positive relation with malingering. Although instructive, these correlational data do not address whether the assessment of psychopathy is vulnerable to specific response styles. This study examined 2 response styles among adolescent offenders in the context of pending adjudication: social desirability and social nonconformity. On 3 measures of psychopathy (i.e., Psychopathy Checklist: Youth Version, Psychopathy Screening Device, and Self-Report of Psychopathy-Second Edition), a simulation design was employed with a realistic scenario, incentives for successful deception, and appropriate manipulation checks. Results indicated moderate to large effect sizes for social desirability and large effect sizes for social nonconformity. The implications of these results for the clinical assessment of psychopathy are discussed.     

A developmental perspective on personality in emerging adulthood: childhood antecedents and concurrent adaptation

Personality and competence were examined in a community sample of 205 children ages 8-12 who were followed up 10 years later in emerging adulthood (ages 17-23). Adult Positive Emotionality (PEM), Negative Emotionality (NEM), and Constraint (CON) were presaged by childhood personality. PEM was associated with current success in social and romantic relationships. Low CON was associated with childhood and current antisocial conduct. NEM was broadly linked to childhood and current maladaptation, consistent with the possibility that failure in major developmental tasks increases NEM. Findings highlight the pervasive linkage of NEM to maladaptation and suggest that adult personality may develop from processes embedded in childhood adaptation as well as childhood personality.     

Religion and emotional compensation: results from a prospective study of widowhood

Based on recent applications of attachment theory to religion, the authors predicted that the loss of a spouse would cause widowed individuals to increase the importance of their religious/spiritual beliefs. This hypothesis was examined using the Changing Lives of Older Couples sample from which preloss measures of religiosity were available for widowed individuals and matched controls. A total of 103 widowed individuals provided follow-up data, including reports of religious beliefs and grief, at 6 months, 24 months, and 48 months after the loss. Results indicated that widowed individuals were more likely than controls to increase their religious/spiritual beliefs. This increase was associated with decreased grief but did not influence other indicators of adjustment such as depression. Finally, insecure individuals were most likely to benefit from increasing the importance of their beliefs. Results are discussed in terms of the potential value of applying psychological theory to the study of religion.     

The influence of object size and surface shape on shape constancy from stereo

The failure of shape constancy from stereoscopic information is widely reported in the literature. In this study we investigate how shape constancy is influenced by the size of the object and by the shape of the object's surface. Participants performed a shape-judgment task on objects of five sizes with three different surface shapes. The shapes used were: a frontoparallel rectangle, a triangular ridge surface, and a cylindrical surface, all of which contained the same maximum depth information, but different variations in depth across the surface. The results showed that, generally, small objects appear stretched and large objects appear squashed along the depth dimension. We also found a larger variance in shape judgments for rectangular stimuli than for cylindrical and ridge-shaped stimuli, suggesting that, when performing shape judgments with cylindrical and ridge-shaped stimuli, observers rely on a higher-order shape representation.     

Effects of gender and sex role orientation on help-seeking attitudes

This study investigated the effects of gender and sex role orientation (masculinity and femininity) on attitudes toward seeking professional psychological help in a sample of 163 student trainee teachers (52 males and 111 females) in Singapore. The mean age of students was 25.39 years (SD = 3.80). ANOVAs revealed statistically significant main effects for gender and femininity on attitudes toward help-seeking. Specifically, females were reported to have more positive overall attitudes toward professional help-seeking and were more willing to recognize a personal need for professional help compared to males. Femininity significantly influenced students’ level of stigma tolerance. These findings suggest that both gender and sex role orientation play an independent role in influencing help-seeking attitudes. In addition, these variables appear to have a differential impact on different aspects of helpseeking.     

View sensitivity increases for same-shape matches if mismatches show pairs of more similar shapes

Lawson, Bülthoff, and Dumbell (2003) found increased view sensitivity when more similar shapes had to be discriminated. Their sequential picture-picture matching studies showed depth-rotated views of novel, complex, 3-D objects. However, with a similar task and stimuli, Hayward and Williams (2000) found no variation in view sensitivity on same-shape match trials depending on whether similar or dissimilar pairs of shapes were shown on mismatch trials. Thus view sensitivity increases from dissimilarshape mismatches to similar-shape mismatches to same-shape matches (Lawson et al., 2003). However, view sensitivity may not increase on same-shape matches if those trials are combined with similarrather than dissimilar-shape mismatches (Hayward & Williams, 2000). The latter result was reexamined here. Matches were view sensitive given even the dissimilar-shape mismatch context. This view sensitivity increased in the medium and especially the hard contexts that showed similar shapes on mismatches. Thus, indirectly increasing shape similarity via mismatch context modulated view-change effects (cf. Hayward & Williams, 2000).     

Predictors of treatment outcome in dually-diagnosed antisocial youth: an initial study of forensic inpatients

The safe and effective management of adolescent offenders is a top priority for inpatient forensic programs. Treatment successes were examined for adolescent offenders on four parameters, specifically hospital course, level of improvement, time to discharge, and rapidity of improvement. Hospital course was predicted primarily by the breadth of polysubstance abuse with modest but independent contributions by psychopathic characteristics, and aggressive conduct-disorder symptoms. An important finding for treatment was that level of improvement at discharge was only marginally affected by psychopathic traits. In addition, rapidity of improvement was predicted only by decreased polysubstance abuse. Approximately one-fourth of the adolescent offenders experienced a substantial decrease in psychopathic characteristics. This finding was unexpected because the generic treatment program did not target the core elements of psychopathy. Even in the absence of nontreatment controls, this diminution of psychopathic traits in 25% of adolescent offenders raises important questions about the temporal stability of these traits and their potential amenability to generic interventions.     

Posttraining increases in REM sleep intensity implicate REM sleep in memory processing and provide a biological marker of learning potential

Posttraining rapid eye movement (REM) sleep has been reported to be important for efficient memory consolidation. The present results demonstrate increases in the intensity of REM sleep during the night of sleep following cognitive procedural/implicit task acquisition. These REM increases manifest as increases in total number of rapid eye movements (REMs) and REM densities, whereas the actual time spent in REM sleep did not change. Further, the participants with the higher intelligence (IQ) scores showed superior task acquisition scores as well as larger posttraining increases in number of REMs and REM density. No other sleep state changes were observed. None of the pretraining baseline measures of REM sleep were correlated with either measured IQ or task performance. Posttraining increases in REM sleep intensity implicate REM sleep mechanisms in further off-line memory processing, and provide a biological marker of learning potential.
