Evaluating Open-Ended Parent Reports and Direct Preference Assessments to Identify Reinforcers for Young Children With Autism

Little research has evaluated open-ended parent reports to identify reinforcers for children with autism. This study evaluated open-ended parent reports and direct preference assessments for six young children with autism in home-based therapy. Results indicated little correspondence between parent reports and direct assessment assessments for all but one child. However, a follow-up reinforcer assessment with two children showed that the top ranked stimulus from both assessments functioned as reinforcers, with one child demonstrating higher levels of responding for the top ranked stimulus from the parent report. Results tentatively support open-ended parent reports to identify reinforcers for young children with autism.     

Rumination is independently associated with poor psychological health: Comparing emotion regulation strategies

Objective: Emotion regulation (ER) strategies are related to psychological health, with most work examining reappraisal and suppression. Yet, emerging findings suggest that rumination may have stronger relationships with psychological health, namely depression, than other ER strategies. This paper replicated and extended this work by testing whether rumination was independently associated with a range of poor psychological health risk indicators and outcomes. In addition, it explored whether the reason why rumination is so deleterious to health is because it underlies the stress–health relationship.

Design: Participants (n = 218) completed measures online.

Main outcome measures: Surveys assessed ER strategies (reappraisal, suppression, proactive coping, emotion support seeking, and rumination), health risk indicators (hostility, optimism, self-esteem), health outcomes (depression, poor sleep quality, anxiety) and perceived chronic stress.

Results: Multivariate regression analyses revealed rumination as the only ER strategy with a consistent independent effect on all the health risk indicators and outcomes. Bootstrapping analyses revealed indirect effects of perceived chronic stress on all the health variables via rumination.

Conclusion: Rumination had a deleterious relationship with psychological health, perhaps because rumination underlies the relationship between stress and psychological health. Results have implications for interventions, particularly emphasizing the need to target ruminative thinking after stressful experiences.     

Beliefs about surgery: Development and validation of an instrument to assess cognitive representations about surgery,in the context of a chronic illness

Objectives: Within a trial of medical and surgical treatments for gastro-esophageal reflux disease (GORD), involving randomised arms and preference arms, we tested the applicability of the Beliefs about Medicines Questionnaire (BMQ) and developed and tested the validity of a new Beliefs about Surgery Questionnaire (BSQ). Methods: Patients with GORD (N = 43) were interviewed to elicit their beliefs about medical and surgical treatments. These contributed to the development of BSQ items. The BMQ and BSQ were completed by trial participants at baseline (randomised trial: N = 325; preference trial: N = 414). Factor analysis and discriminant function analysis were used to assess validity. Results: Principal components analysis (PCA) largely replicated the four-factor BMQ structure. PCA of the combined BMQ/BSQ yielded six factors explaining 54.5% variance. BSQ items loaded onto distinct factors, demonstrating divergence from BMQ. As predicted, BMQ/BSQ scores enabled correct classification of 78.5% of participants to medication and surgery groups in the preference trial (χ²(6) = 205.9, p < 0.001) but only 54.5% (no better than chance) in the randomised trial (χ²(6) = 9.4, p = 0.154). Conclusions: The BSQ is a valid measure of perceptions about surgical treatments for GORD. With the BMQ, it provides information that may guide patients’ choices about treatment. This measure may be applicable to other conditions.     

Emotional competence and quality of life of children with asthma: The mediating effect of coping strategies

This study explored the mediating effect of coping strategies on the relationship between emotional competence (EC) and quality of life (QOL) among children with asthma. Participants were 87 children (M age?=?11.72, SD?=?2.58) with controlled and partially controlled asthma, undergoing everyday treatment. They filled in questionnaires assessing EC, coping strategies and QOL. Results showed that the association between some ECs and the QOL of children with asthma was fully mediated by two maladaptive cognitive coping strategies. Among children with asthma, a greater ability to differentiate their emotions, a reduced attention to bodily signals of emotions and a reduced analysis of their current emotional state were related to decreased engagement in two coping strategies (‘Ignoring Asthma’ and ‘Worrying about Asthma’), which in turn increased their QOL. These findings show that EC has an indirect effect on QOL through very specific coping strategies. They also emphasise the importance of screening EC in children with asthma and the importance of developing and using multidisciplinary interventions for them.     

Emotional (Non-)Expression and Health: Data,Questions, and Challenges

The available evidence on the relationship between expression and non-expression of emotions (E/NE) and health is selectively and critically reviewed. It is concluded that research in this field still lacks conceptual lucidity with regard to the many existing E/NE concepts. Despite the fact that few studies adopted appropriate designs for examining causal relationships, some intriguing results have been reported showing promise for the future. These results involve prospective associations between E/NE and chronic disease, such as cardiovascular disease and HIV infection related outcomes. Future studies have to better discriminate between (i) various forms of E/NE, (ii) different (social) contexts of E/NE as well as different cognitive decision processes underlying E/NE, and (iii) individuals for whom different forms of E/NE may be adaptive. We recommend that besides (quasi)experimental studies on the potential mechanisms involved, more prospective studies are conducted in this field in order to allow for causal inferences.     

Methylphenidate,Interstimulus Interval,and Reaction Time Performance of Children with Attention Deficit/Hyperactivity Disorder: A Pilot Study

Thirteen children with attention deficit/hyperactivity disorder (ADHD: DSM-IV-TR) participated in the pilot study. They carried out a Go/No-Go test with a short (2 seconds) and long (6 seconds) interstimulus interval (ISI) when on placebo and a therapeutic dose of methylphenidate (MPH). For the long-ISI placebo condition the responses were slow and inaccurate. This pattern of response may be due to underactivation of the readiness-to-respond state that is not fully controlled by effort allocation. Speed of response and accuracy were enhanced during the short-ISI placebo condition and the long-ISI MPH condition. However, the combined effect (short ISI and MPH) resulted in a fast but inaccurate response style. This pattern of response may be due to overactivation of the readiness-to-respond state. The data of the pilot study support the stimulus shift hypothesis: MPH administration result in deterioration on tests on which children had previously done well (short ISI plus placebo versus short ISI plus MPH). In addition, the data support the idea that ADHD is associated with poor state regulation rather than motivational (delay aversion) theories or temporal-processing/time-estimation theories of ADHD. The pilot study defined empirically an issue for further study with the larger controlled sample.     

Site preference of refractory elements in γ′-Ni3Al alloyed with Ru

The influence of ruthenium (Ru) on the partitioning behavior of W, Re and Cr in γ′-Ni₃Al has been studied using the Dmol3 method based on the density functional theory. The calculated results show that W, Re and Cr have a preference for the Ni site in γ′-Ni₃Al alloyed with Ru. When Ru substitutes the central Ni atom, the site preference for W, Re and Cr varies. Furthermore, an electronic structure analysis of the alloy in terms of the Mulliken population and partial density of states was performed to elucidate the alloying mechanism of Ru in γ′-Ni₃Al. The results show that the strengthening effect of Ru in the alloy arises from a reduction in the binding energy of Ru as well as p-orbital hybridization between Ru and the host atoms.     

Regulating Biopharming: The Prism of Farmer Knowledge

Farmers have local knowledge relevant to the prospective assessment of biopharming—the farming of transgenic plants and animals genetically modified to produce pharmaceutical substances for use in humans or animals. However, biopharming regulatory regimes are being constructed in ways that render farmers' knowledge irrelevant. The exclusion of farmer knowledge is traceable to what we call its politico-epistemic unworkability as regulatory knowledge in regulatory regimes characterised not only by a focus on risk but also by pre-commitments to market-driven innovation and individual freedom of choice. Such innovation requires predictability in the regulatory environment, which is supplied in part through regulatory authorities' adoption of risk-assessment methodologies that both assume predictability (of natural and social worlds) and generate predictable decision outcomes. These regulatory approaches are co-constituted with scientific knowledge of gene flow developed through studies that can demonstrate a reliable and readily modellable decline of undesirable effect across space or time and therefore make possible the setting of clear and workable parameters for risk management. The farmers' knowledge discussed here highlights the extent to which this is a process of co-production. Moreover, it suggests that the claimed economic advantages of outdoor biopharming, achieved through the substitution of agronomic practice for laboratory infrastructure, depend both on natural processes that always also threaten to undermine confinement and on the habitus of successful farmers, which may in fact be incompatible with the kind of risk management that biopharming requires.     

The eACS: Attentional control in the presence of emotion

We present a questionnaire – The Emotional Attentional Control Scale (eACS) – An adaptation of the original Attentional Control Scale (ACS) that assesses the voluntary control of attention. A low score on the ACS has been associated with high levels of anxiety and depression. As the ACS items are affectively neutral, some people scoring high on the ACS may still show low levels of attentional control (AC) in more emotionally-demanding situations. We propose that the eACS, which focuses on the emotional modulation of AC, may explain additional variance in AC deficits associated with psychopathology.     

Remember me? Psychopathic traits and emotional memory in an undergraduate sample

We investigated the effects of psychopathy on emotional memory among a predominantly female undergraduate sample. Undergraduates (N = 153, mean age = 20.1; 80.1% female; 57.1% Caucasian) completed a facial memory task. Participants were presented with a series of faces (sad, scared, angry, happy, neutral), completed a self-report measure of psychopathy, and were presented with another series of faces (with some from the first phase, and some new). Participants were asked whether they recognized each face from the first set, and reaction time (RT) was measured. Although memory for emotional faces did not differ from neutral faces, there were main effects of emotion, gender and psychopathy on RT. A significant 3-way interaction revealed that males who were higher in psychopathy had slower RTs; they were slow to remember sad, angry and neutral faces. In conclusion, psychopathy may affect emotional memory differently across gender. Specifically, undergraduate men, but not women, with higher psychopathy levels may show impaired memory for emotional faces. Implications for future studies of emotional memory and psychopathy are discussed.
