Competing stimulus assessments (CSA) have been used to identify stimuli that are associated with reduced levels of problem behavior, presumably as a function of reinforcer competition. Following a standard CSA in which stimuli simply were made available, 2 more CSAs were conducted with additional components designed to enhance reinforcer competition: re-presentation of stimuli and response blocking for self-injury. The results obtained from each CSA were validated in an extended treatment analysis. The study illustrates how the effects of additional components designed to enhance reinforcer competition can be evaluated efficiently in the context of a CSA. 相似文献

Use of Gilliam Asperger's disorder scale in differentiating high and low functioning autism and ADHD
Mayes SD Calhoun SL Murray MJ Morrow JD Yurich KK Cothren S Purichia H Bouder JN 《Psychological reports》2011,108(1):3-13
Little is known about the validity of Gilliam Asperger's Disorder Scale (GADS), although it is widely used. This study of 199 children with high functioning autism or Asperger's disorder, 195 with low functioning autism, and 83 with attention deficit hyperactivity disorder (ADHD) showed high classification accuracy (autism vs. ADHD) for clinicians' GADS Quotients (92%), and somewhat lower accuracy (77%) for parents' Quotients. Both children with high and low functioning autism had clinicians' Quotients (M=99 and 101, respectively) similar to the Asperger's Disorder mean of 100 for the GADS normative sample. Children with high functioning autism scored significantly higher on the cognitive patterns subscale than children with low functioning autism, and the latter had higher scores on the remaining subscales: social interaction, restricted patterns of behavior, and pragmatic skills. Using the clinicians' Quotient and Cognitive Patterns score, 70% of children were correctly identified as having high or low functioning autism or ADHD. 相似文献

This article describes the development and validation of the Internalized Racial Oppression Scale (IROS) for Black individuals in 2 studies using a total sample of 468 Black college students. The IROS is intended to measure the degree to which racial oppression is internalized and replicated by Black individuals in the United States. An exploratory factor analysis suggested a five-factor solution: Belief in the Biased Representation of History (BRH), Devaluation of the African Worldview and Motifs (DAW), Alteration of Physical Appearance (APA), Internalization of Negative Stereotypes (INS), and Hair Change (HC). Confirmatory factory analysis supported an adequate model fit of a four-factor model: BRH, APA, INS, and HC. All factors of the IROS were positively correlated with the Pre-Encounter subscale of the Racial Identity Attitude Scale (RIAS-B; J. E. Helms & T. A. Parham, 1996), and 4 of the factors were negatively correlated with the Immersion/Emersion subscale of the RIAS-B. Four factors of the IROS were negatively correlated with all subscales and total scores of the African Self-Consciousness Scale (J. A. Baldwin & Y. R. Bell, 1985). These results provide some support of the validity of the IROS. 相似文献

Delay discounting occurs when individuals are increasingly willing to accept less than the full amount of something to receive it immediately as the delay to the full amount increases. Previous research has reported different "domains" of commodities, with discounting in one domain not being informative about discounting in another. In the present study, 283 participants completed a delay-discounting task with 1 of 2 sets of 5 commodities identical to those used in previous research (Weatherly, Terrell, & Derenne, 2010). Confirmatory factor analyses determined that the observed discounting conformed to previously reported domains. Also replicated was finding that discounting differs both as a function of commodity and how the commodity is framed. These results provide strong support for the idea that temporal decisions made about certain consequences may not necessarily be informative about how an individual will make decisions about other consequences. Also, the framing of the decision can significantly influence observed levels of discounting, potentially clouding interpretation. 相似文献

This study examined the extent to which maternal attention-deficit/hyperactivity disorder (ADHD) symptoms predict improvement
in child behavior following brief behavioral parent training. Change in parenting was examined as a potential mediator of
the negative relationship between maternal ADHD symptoms and improvement in child behavior. Seventy mothers of 6–10 year old
children with ADHD underwent a comprehensive assessment of adult ADHD prior to participating in an abbreviated parent training
program. Before and after treatment, parenting was assessed via maternal reports and observations and child disruptive behavior
was measured via maternal report. Controlling for pre-treatment levels, maternal ADHD symptomatology predicted post-treatment
child disruptive behavior problems. The relation between maternal ADHD symptomatology and improvement in child behavior was
mediated by change in observed maternal negative parenting. This study replicated findings linking maternal ADHD symptoms
with attenuated child improvement following parent training, and is the first to demonstrate that negative parenting at least
partially explains this relationship. Innovative approaches combining evidence-based treatment for adult ADHD with parent
training may therefore be necessary for families in which both the mother and child have ADHD. Larger-scale studies using
a full evidence-based parent training program are needed to replicate these findings. 相似文献

Objective
To explore the interplay of maternal depressive symptoms on the infant limbic-hypothalamic-pituitary axis (LHPA) and neurological development.Design
Pregnant women were monitored for depressive symptoms using the Beck Depression Inventory (BDI) at 28, 32, and 37 weeks of gestation and at delivery. A mixture growth curve analysis divided the women into three risk groups: low/stable, intermediate, and high/increasing depression based on BDI scores. The infant neuroendocrine system was examined using cord blood for adrenocorticotrophic hormone (ACTH) and cortisol measurements. Two-week-old infants were examined using Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS).Results
Infants born to women of the high/increasing depression group had significant ACTH elevation at birth. On NNNS examination, these infants were more hypotonic and habituated to auditory and visual stimuli.Conclusion
When compared to non-depressed women, maternal depressive symptoms, even in the absence of major depressive disorder, appeared to facilitate a different developmental pathway for the infant LHPA and early neurological development. 相似文献968.

Responses to threat occur via two known independent processing routes. We propose that early, reflexive processing is predominantly tuned to the detection of congruent combinations of facial cues that signal threat, whereas later, reflective processing is predominantly tuned to incongruent combinations of threat. To test this prediction, we examined responses to threat-gaze expression pairs (anger versus fear expression by direct versus averted gaze). We report on two functional magnetic resonance imaging (fMRI) studies, one employing prolonged presentations (2 s) of threat-gaze pairs to allow for reflective processing (Study 1), and one employing severely restricted (33 ms), backward masked presentations of threat-gaze pairs to isolate reflexive neural responding (Study 2). Our findings offer initial support for the conclusion that early, reflexive responses to threat are predominantly tuned to congruent threat-gaze pairings, whereas later reflective responses are predominantly tuned to ambiguous threat-gaze pairings. These findings highlight a distinct dual function in threat perception. 相似文献

Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival. 相似文献

Experiential avoidance and distress intolerance play a central role in novel behavior therapies, yet they appear to overlap
considerably the REBT concept of low frustration tolerance. Using baseline data from 100 adult cigarette smokers enrolled
in a clinical trial of smoking cessation therapies, the present study evaluated the convergent validity of common questionnaire
measures of experiential avoidance (Acceptance and Action Questionnaire; AAQ; Hayes et al. 2004, and Avoidance and Inflexibility Scale: AIS; Gifford et al. 2004) and behavioral measures of distress tolerance (computerized Mirror Tracing Persistence Task: MTPT-C: Strong et al. 2003; computerized Paced Auditory Serial Addition Task; PASAT-C; Lejuez et al. 2003). The distress tolerance measures correlated significantly (r = .29) with one another. However, the questionnaire measures of experiential avoidance did not correlate with each other,
nor with the behavioral measures. Further research is needed on the validity of measuring experiential avoidance by self-report
and of the overlap versus distinctiveness of seemingly similar constructs such as experiential avoidance, distress tolerance,
and frustration tolerance. 相似文献
