Judgments about estrogen replacement therapy: The role of age, cognitive abilities, and beliefs.

This study investigated age, cognitive abilities, health beliefs, and other factors in women's judgments about effective treatments for menopause. Women (N?=?102) ranging in age from 20 to 79 read a vignette about a woman facing a decision about Estrogen Replacement Therapy (ERT) and then made judgments about what should be done. Participants also completed a battery of questions pertaining to ERT and cognitive abilities. Path-analytic techniques were used to determine the role of specific cognitive abilities and the representation of menopause and its treatment in making judgments about ERT treatments. Cognitive abilities had direct effects on treatment decisions. Education affected the number of perceived options for treatment. Age and education indirectly affected treatment decisions, operating through cognitive abilities. Factors related to the mental representation of menopause had no direct effects and few indirect effects on treatment decisions. Potential mechanisms that can help older adults compensate for declines in cognitive abilities in medical decisions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing a public health approach to delay onset and progression of adolescent substance use: Latent transition and log-linear analyses of longitudinal family preventive intervention outcomes.

This study examined the effects of the Iowa Strengthening Families Program (ISFP) and the Preparing for the Drug-Free Years program (PDFY) on young adolescent transitions from nonuse of substances to initiation and progression of substance use. Analyses incorporated 3 waves of data collected over a 2.5-year period from 329 rural young adolescents. Outcomes were analyzed by using log-linear models that incorporated substance use status frequencies derived from latent transition analyses. Effects on delayed substance use initiation were shown for both the ISFP and the PDFY at a 2-year follow-up. Also at this follow-up, the PDFY showed effects on delayed progression of use among those previously reporting initiation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Analysis of Residential Irrigation Distribution Uniformity

Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricultural Engineers standard and Florida Mobile Irrigation Laboratory (MIL) procedures. The modified version included a larger sample size to ensure complete sample collection over the entire irrigated area. The standard MIL procedure may overestimate the uniformity for residential systems. From the tests on residential irrigation systems, the average low quarter distribution uniformity (DUlq) value was calculated as 0.45. Rotary sprinklers resulted in significantly higher DUlq compared to fixed pattern spray heads with 0.49 compared to 0.41, respectively. From uniformity tests performed on rotor and spray heads under ideal conditions, rotor heads had more uniform distributions than the spray heads of 0.55 compared to 0.49, respectively. Spray heads had better uniformity when fixed quarter circle nozzles were used as opposed to adjustable nozzles. Both residential irrigation system and controlled tests resulted in (DUlq) at the low end of industry guidelines. Residential irrigation system uniformity can be improved by minimizing the occurrence of low pressure in the irrigation system and by ensuring proper spacing is used in design and installation.     

Achievement goals and daily school experiences among adolescents with Asian, Latino, and European American backgrounds.

The current study examined the fit of a 2 × 2 achievement goal model among a diverse sample of nearly 700 10th-grade students, distinguishing between both mastery and performance goals and approach and avoidance orientations. Additionally, relationships between achievement goals and GPA and intrinsic value of school were examined, and adolescents' interpretations of daily school experiences and feelings were found to mediate these relationships. Together, these findings suggest that experiences in adolescents' daily lives help explain the relationship between goals and achievement outcomes.

Binding ties: Closeness and conflict in adult children's caregiving relationships.

The authors used a path model to test the hypothesis that emotional closeness and conflict between adult–child caregivers (N?=?90) and their impaired parents mediated the impact of the parents' functional and cognitive impairment on the caregivers' subjective stress, subjective effectiveness, and depression. Closeness mediated the relationship between cognitive impairment and both stress and effectiveness, whereas conflict mediated cognitive impairment for all 3 outcomes and generally accounted for more variance. There was limited evidence that functional impairment was mediated by the quality of the relationship. Results highlight the importance of both positive and negative ties as intervening mechanisms influencing caregivers' well-being, especially in the presence of cognitive dysfunction.

Impairment in category fluency in ischemic vascular dementia.

The underlying mechanisms for impaired output on letter (F, A, and S) and category (e.g., animal) word list generation (WLG) tasks in subcortical ischemic vascular dementia (IVD) were investigated. Normal control (NC) and Alzheimer's disease (AD) participants were also studied. IVD and NC participants performed better on category than letter WLG tasks, whereas the opposite was observed among AD participants. IVD participants produced fewer responses than AD participants on letter WLG tasks, but there was no difference between AD and IVD participants on the "animal" WLG task. AD participants scored lower than IVD and NC participants on animal WLG indexes measuring semantic knowledge. There were few differences between IVD and NC participants. The reduced output on the animal WLG task for IVD participants is consistent with search-retrieval deficits. The reduced output of AD participants may be caused by degraded semantic knowledge.

Elevated levels of impulsivity and reduced place conditioning with d-amphetamine: Two behavioral features of adolescence in mice.

Human adolescents may have experience with easily available psychoactive drugs. Impulsivity and/or peculiarities in reward systems may play a role. These variables were studied in adolescent (Postnatal Day [PND] 30-49) and adult (PND > 60) CD-1 mice. In Experiment 1 (impulsivity), food-restricted mice were tested in operant chambers with 2 nose-poking holes that delivered 1 food pellet immediately or 5 pellets after a delay, respectively. Delay length was increased over days (0-100 sec). Adolescent mice showed a shift to the left in the intolerance-delay curve, as well as enhanced demanding when nose-poking was not reinforced. In Experiment 2 (place conditioning with d-amphetamine at 0.0, 1.0, 2.0, 3.3, or 5.0 mg/kg for 3 days), adolescent mice showed no reliable evidence of place conditioning when compared with adults. Hence, 2 main features of adolescence were elevated impulsivity and restlessness, and low (or absent) rewarding efficacy of amphetamine.

The complexities of eliciting and assessing children's statements.

The authors agree with the main elements of M. Bruck and S. J. Ceci's (see record 1996-09956-001) amicus curiae brief for the case of State v. Michaels, but they believe that 4 specific aspects of child sexual abuse investigations deserve a more constructive emphasis. Research has tended to concentrate on the suggestibility of children and neglected other topics that may be of great utility to those who investigate suspected cases of child sexual abuse. More attention should have been paid in the brief to the complexities of assessment and the special characteristics of the Wee Care case. Too much emphasis has been placed on children and not nearly enough attention on remedial actions to minimize the problems associated with suggestion. Finally, research shows that it may be possible to develop reliable and valid techniques to assess child sexual abuse allegations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Remediation revisited.

This article replies to comments by J. C. Gonsiorek (see record 84-33291), P. Orr (see record 84-33300), and L. S. Brown (see record 84-33284 ) on M.J. Layman and J.R. McNamara's (see record 84-33293) work on remediation and ethics violations. The authors acknowledge various distinctions they have introduced but continue to argue that sexual violations are outstandingly egregious. They agree that making amends is important but wonder about the practicalities of working this into rehabilitation. Lack of empirical knowledge about what is prescribed for remediation is reemphasized. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
