OBJECTIVE: The Resources for Health trial evaluates a social-ecologically based lifestyle (physical activity and diet) intervention targeting low-income, largely Spanish-speaking patients with multiple chronic conditions. DESIGN: A randomized controlled trial was conducted with 200 patients recruited from an urban community health center and assigned to intervention and usual care conditions. Intervention involved 2 face-to-face, self-management support and community linkage sessions with a health educator, 3 follow-up phone calls, and 3 tailored newsletters. MAIN OUTCOME MEASURES: Primary outcomes measured at 6-months were changes in dietary behavior and physical activity. Changes in multilevel support for healthy living were evaluated as a secondary outcome. RESULTS: After adjustment for age, sex, language, and number of chronic conditions, significant intervention effects were observed for dietary behavior and multilevel support for healthy lifestyles but not for physical activity. CONCLUSION: The Resources for Health intervention provides an effective and practical model for improving health behavior among low-income, Spanish-speaking patients with multiple chronic conditions. 相似文献

When neural events are analyzed as stimuli and responses, functional relations among them and among overt stimuli and responses can be unveiled. The integration of neuroscience and the experimental analysis of behavior is beginning to provide empirical evidence of involvement of neural events in the three-term contingency relating discriminative stimuli, responses, and consequences. This paper is aimed at highlighting exemplar instances in the development of this issue. It has long been known that the electrical stimulation of certain cerebral areas can have a reinforcing function. Extraordinary technological advances in recent years show that neural activity can be selected by consequences. For example, the activity of in vitro isolated neurons that receive dopamine as a reinforcer functions as a cellular analogue of operant conditioning. The in vivo activity of populations of neurons of rats and monkeys can be recorded on an instant-to-instant basis and can then be used to move mechanical arms or track a target as a function of consequences. Neural stimulation acts as a discriminative stimulus for operant responses that are in turn maintained by neural consequences. Together with investigations on the molecular basis of classical conditioning, those studies are examples of possibilities that are being created for the study of behavior-environment interactions within the organism. More important, they show that, as an element in the three-term contingency, neural activity follows the same laws as other events. 相似文献

Two studies were conducted to examine the psychometric properties and correlates of the Perfectionism Cognitions Inventory
(PCI) when administered to clinical samples. The PCI is a 25-item measure of automatic thoughts with themes involving perfectionism
and beliefs that perfection should be attained. Analyses indicated that the PCI is unidimensional and it has adequate internal
consistency. Correlational analyses confirmed that the PCI is associated with psychological distress and deficits in cognitive
self-management, including lack of self-reinforcement, lack of a positive self-focus, and perfectionistic inflexibility. Moreover,
tests of incremental validity revealed that the PCI accounts for unique variance in levels of anxiety and depression symptoms
after removing variance attributable to trait perfectionism dimensions. Overall, the findings suggest that automatic thoughts
involving perfectionistic themes can be assessed in a reliable and valid manner in clinical samples. Moreover, it is important
to assess perfectionism cognitions as a supplement to trait perfectionism measures when evaluating the role of perfectionism
in psychological distress and associated deficits in cognitive self-control.

We evaluated the relationship between motor and neuropsychological deficits in subjects affected by amnestic Mild Cognitive Impairment (aMCI) and early Alzheimer's Disease (AD). Kinematics of goal-directed movement of aMCI and AD subjects were compared to those of age-matched control subjects. AD showed a slowing down of motor performance compared to aMCI and controls. No relationships were found between motor and cognitive performances in both AD and aMCI. Our results suggest that the different motor behaviour between AD and aMCI cannot be related to memory deficits, probably reflecting the initial degeneration of parietal-frontal circuits for movement planning. The onset of motor dysfunction in early AD could represent the transition from aMCI to AD. 相似文献

The present research examines the semantic priming effects of a centrally presented single prime word to which participants were instructed to either "attend and remember" or "ignore". The prime word was followed by a central probe target on which the participants made a lexical decision task. The main variables manipulated across experiments were prime duration (50 or 100 ms), the presence or absence of a mask following the prime, and the presence (or absence) and type of distractor stimulus (random set of consonants or pseudowords) on the probe display. There was a consistent interaction between the instructions and the semantic priming effects. Relative to the "attend and remember" instruction, an "ignore" instruction produced reduced positive priming from single primes presented for 100 ms, irrespective of the presence or absence of a prime mask, and regardless of whether the probe target was presented with or without distractors. Additionally, reliable negative priming was found from ignored primes presented for briefer durations (50 ms) and immediately followed by a mask. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed. 相似文献

Despite overwhelming evidence that gender plays a significant role in the course of numerous psychological disorders, researchers have historically neglected to address gender similarities and differences in their research. Previous reviews of the psychological literature have indicated that personality, psychotherapy, and behavioral psychology journals have published few studies that focus on gender comparisons. The current review examined published articles in three prominent behavioral psychology journals—Behavior Therapy, Behavior Modification, and Behaviour Research and Therapy—from their inception through 2001. Raters coded each article (N = 4,635) for gender content in the title or abstract, analyses of gender differences, and discussion of gender. Overall, very few articles focused on gender content in the title, abstract, or discussion or analyzed data by gender. Implications of these results and suggestions for enhancing attention to gender comparisons are discussed. 相似文献

The results of an exploratory national study carried out in Italy using Osgood's Semantic Differential Scales (Osgood, Suci, & Tannenbaum, 1957) with parents of 100 normal 6- to 11-yr.-old children in mainstream classrooms are reported. The aim was to devise a simple tool to be used to explore parents' perceptions of their children in this age group. Parents were asked to rate "my child" using some of Osgood's Semantic Differential Scales especially adapted for this study. Participants were 97 fathers and 100 mothers. Fathers were 32 to 57 years of age (M = 43.2, SD = 5.4), mothers were 29 to 49 years of age (M = 39.7, SD =4.4). In factor analysis four factors were identified: Activity, Evaluation, Emotions evoked by the child, Personality/Physical contact. Average factor scores were significantly different. There were no significant differences between fathers and mothers on the four factor scores. Children were more positively evaluated the younger they were. 相似文献

Despite a general consensus in the United States that overtly racist acts are unacceptable, many ambiguous situations in everyday life raise questions of whether racism has influenced a person's behavior in an interracial encounter. The authors of the present study sought to (a) examine simultaneously an array of variables thought to be related to perceived racism and (b) investigate how the contribution of these variables may differ with respect to the asymmetry hypothesis, which suggests that acts of discrimination from a dominant person toward a subordinate person will be viewed as more biased than if the situation were reversed. The authors used a dual structural equation modeling approach. Results indicated that ethnic identity significantly predicted perceived racism. In addition, the extent to which cognitive interpretation style significantly predicted perceived racism depended on the ethnicity of participants involved in the interaction. 相似文献

This project provides information on how nonpatient children perform on the Rorschach test, administered and scored following Exner's guidelines (1995). Lis, Parolin, Zennaro, and Mazzeschi (2001) previously reported initial data for 70 nonpatient children living in Italy who were administered this instrument by graduate and postgraduate students in a 2-year research course at the Psychotherapy School of the University of Padua between July 1998 and February 2001. The current study is an extension of that work and includes information on an additional 153 participants gathered between November 2002 and December 2006. The total number of participants includes 223 individuals, 75 5-7-year-old children in the first level of elementary school, and 148 8-11-year-old children in the second level of elementary school. Exclusion criteria are described, and interrater reliability statistics at the response level for scoring segments are reported using percent agreement and iota. Rorschach Comprehensive System (CS) findings are presented. 相似文献

While depression is a significant worldwide health problem, fewer than half of individuals seek care. Faith-based communities
may play an important role in improving the knowledge of and linkage to depression care. Focus groups of Caucasian and African-American
clergy were conducted to explore these issues. Using a grounded theory approach five themes emerged, including explanatory
models of depression, barriers and facilitators to care, and recommendations for involving religious communities. A model
of depression care pathways was constructed that integrates secular and spiritual approaches. The findings highlight the need
for targeted interventions to build trust between clergy and mental health professionals.
