Salad = success and fries = failure? Conceptualizing and assessing self‐control outcome measures in food decision‐making research

Researchers studying decisions about food utilize a wide variety of measures to assess self‐control outcomes in experimental studies. However, it is often unclear whether or not the chosen dependent variables truly implicate self‐regulatory mechanisms in decision making. In the present research, we provide a conceptual framework for evaluating self‐control outcome measures, concentrating specifically on the domain of food and eating self‐control decisions. We propose and empirically examine the essential characteristics [i.e., (i) recognized as self‐control relevant by study population, (ii) related to individual differences in self‐control, and (iii) recognized as self‐control relevant by individual] of good self‐control outcome measures and provide specific methodological recommendations (including the “rank‐then‐choose” method) for capturing exhibited self‐control in the domain of food decision making. Our conceptual developments and recommendations seek to enhance the consistency, efficiency, and effectiveness of food‐related decision research. Copyright © 2015 John Wiley & Sons, Ltd.     

Propositional Reasoning that Tracks Probabilistic Reasoning

This paper concerns the extent to which uncertain propositional reasoning can track probabilistic reasoning, and addresses kinematic problems that extend the familiar Lottery paradox. An acceptance rule assigns to each Bayesian credal state p a propositional belief revision method ${\sf B}_{p}$ , which specifies an initial belief state ${\sf B}_{p}(\top)$ that is revised to the new propositional belief state ${\sf B}(E)$ upon receipt of information E. An acceptance rule tracks Bayesian conditioning when ${\sf B}_{p}(E) = {\sf B}_{p|_{E}}(\top)$ , for every E such that p(E)?>?0; namely, when acceptance by propositional belief revision equals Bayesian conditioning followed by acceptance. Standard proposals for uncertain acceptance and belief revision do not track Bayesian conditioning. The ??Lockean?? rule that accepts propositions above a probability threshold is subject to the familiar lottery paradox (Kyburg 1961), and we show that it is also subject to new and more stubborn paradoxes when the tracking property is taken into account. Moreover, we show that the familiar AGM approach to belief revision (Harper, Synthese 30(1?C2):221?C262, 1975; Alchourrón et al., J Symb Log 50:510?C530, 1985) cannot be realized in a sensible way by any uncertain acceptance rule that tracks Bayesian conditioning. Finally, we present a plausible, alternative approach that tracks Bayesian conditioning and avoids all of the paradoxes. It combines an odds-based acceptance rule proposed originally by Levi (1996) with a non-AGM belief revision method proposed originally by Shoham (1987).     

Role of identity integration on the relationship between perceived racial discrimination and psychological adjustment of multiracial people

This study examined relations between perceived racial discrimination, multiracial identity integration (i.e., racial distance and racial conflict), and psychological adjustment (i.e., distress symptoms, positive affect, and negative affect) of 263 multiracial adults, using an online cross-sectional survey design. As hypothesized, higher levels of perceived racial discrimination was related to lower levels of psychological adjustment (i.e., higher distress symptoms and negative affect). Also, higher levels of multiracial identity integration with low racial conflict was related to higher levels of psychological adjustment (i.e., lower distress symptoms and negative affect), whereas higher levels of multiracial identity integration with low racial distance was related to higher levels of psychological adjustment (i.e., lower negative affect). Finally, multiracial identity integration (i.e., lower racial conflict) moderated the relationship between perceived racial discrimination and psychological adjustment (i.e., negative affect) with results suggesting multiracial identity integration related to low racial conflict buffers the negative effects of perceived racial discrimination on psychological adjustment. Findings from this study are discussed in terms of future research on the psychological well-being of multiracial individuals and implications for clinical practice with multiracial adults.     

Religious Coping and Psychological Distress in Military Veteran Cancer Survivors

Research on the relationship between religious coping and psychological well-being in cancer survivors is limited. Forty-eight veteran cancer survivors completed measures of psychological distress, posttraumatic growth, and positive and negative religious coping. Negative religious coping was associated with greater distress and growth. Positive religious coping was associated with greater growth. Gender, race, and religious affiliation were significant predictors of positive and negative religious coping. Veteran cancer survivors who utilize negative religious coping may benefit from referral to clergy or a mental health professional. Assessment of religious coping may be particularly important for female, non-White, and Christian cancer survivors.     

Youth Appraisals of Inter-parental Conflict and Genetic and Environmental Contributions to Attention-Deficit Hyperactivity Disorder: Examination of GxE Effects in a Twin Sample

Identification of gene x environment interactions (GxE) for attention-deficit hyperactivity disorder (ADHD) is a crucial component to understanding the mechanisms underpinning the disorder, as prior work indicates large genetic influences and numerous environmental risk factors. Building on prior research, children’s appraisals of self-blame were examined as a psychosocial moderator of latent etiological influences on ADHD via biometric twin models, which provide an omnibus test of GxE while managing the potential confound of gene-environment correlation. Participants were 246 twin pairs (total n = 492) ages 6–16 years. ADHD behaviors were assessed via mother report on the Child Behavior Checklist. To assess level of self-blame, each twin completed the Children’s Perception of Inter-parental Conflict scale. Two biometric GxE models were fit to the data. The first model revealed a significant decrease in genetic effects and a significant increase in unique environmental influences on ADHD with increasing levels of self-blame. These results generally persisted even after controlling for confounding effects due to gene-environment correlation in the second model. Results suggest that appraisals of self-blame in relation to inter-parental conflict may act as a key moderator of etiological contributions to ADHD.     

Chinese Christians in America: Attachment to God,Stress, and Well‐Being

This study examined whether attachment to God moderated the relation between perceived stress and well‐being (i.e., life satisfaction and positive affect) among 183 Chinese Christian international students and immigrants. Results showed significant main effects of (a) perceived stress on life satisfaction and (b) secure attachment to God and avoidant attachment to God on life satisfaction and positive affect. There was a significant interaction of perceived stress and avoidant attachment to God on life satisfaction. Specifically, high avoidant attachment to God exacerbated the association between perceived stress and life satisfaction, whereas low avoidant attachment to God buffered the association between perceived stress and life satisfaction.     

Letters of Gratitude: Further Evidence for Author Benefits

This study examined the effects of writing letters of gratitude on three primary qualities of well-being; happiness (positive affect), life-satisfaction (cognitive evaluation), and depression (negative affect). Gratitude was also assessed. Participants included 219 men and women who wrote three letters of gratitude over a 3 week period. A two-way mixed method ANOVA with a between factor (writers vs. non-writers) and within subject factor (time of testing) analysis was conducted. Results indicated that writing letters of gratitude increased participants’ happiness and life satisfaction, while decreasing depressive symptoms. The implications of this approach for intervention are discussed.     

Executive functioning and psychological adjustment in children and youth with spina bifida

Children and adolescents with spina bifida are at risk for poor neuropsychological functioning and psychological outcomes. The relationship between executive functioning and psychological adjustment is an area worthy of investigation in this population. The current study assessed executive functioning and psychological outcomes in a group of children and adolescents with spina bifida (SBM) (n = 51) and nondisabled controls (n = 45). A mediation model was hypothesized, such that Metacognition, as measured by the Behavior Rating Inventory of Executive Function (BRIEF), mediated the relationship between group status (spina bifida versus nondisabled controls) and psychological outcomes. Results indicated that metacognitive skills fully explained the relationship between group and internalizing and depressive symptoms as reported by mothers. In particular, specific components of the BRIEF Metacognition composite were most responsible for this relationship, including Initiate, Working Memory, and Plan/Organize. The study limitations include its cross-sectional nature that precludes drawing conclusions about causality. The results have implications for treatment interventions for children and adolescents with spina bifida and typically developing individuals.
