ADHD Symptoms in Middle Adolescence Predict Exposure to Person-Related Life Stressors in Late Adolescence in <Emphasis Type="Italic">5-HTTLPR</Emphasis> S-allele Homozygotes

Literature suggests that life stressors predict attention-deficit/hyperactivity disorder (ADHD) symptoms and that this relationship is moderated by the serotonin transporter polymorphism (5-HTTLPR). It is less clear whether, on reverse, ADHD symptoms may influence the risk of exposure to life stressors. Furthermore, the role of life stressors may vary across development depending on the type of life stressor. We used threewave longitudinal data of 1,306 adolescents from the general population and clinicreferred cohort of the TRacking Adolescents’ Individual Lives Survey. The 5-HTTLPR genotype (SS, LS, LL), parent-reported ADHD symptoms at three time points (T1: Mage?=?11.2; T2: Mage?=?13.5; T3: Mage?=?16.2 years), and the number of personrelated (‘dependent’) and environment-related (‘independent’) life stressors occurring between measurements (T1-T2, T2-T3) were assessed. Using path analyses, we examined bidirectional relations between exposure to these life stressors and ADHD symptoms between the separate waves moderated by 5-HTTLPR status. Exposure to life stressors did not predict ADHD symptoms. Rather, we found that in 5-HTTLPR Sallele homozygotes, ADHD symptoms in middle adolescence (T2) predicted exposure to the number of person-related life stressors later in adolescence (T2-T3, p?=?0.001). There was no relation with environment-related life stressors. Our study suggests that S-allele homozygotes with higher levels of ADHD symptoms in middle adolescence are more vulnerable to becoming exposed to person-related (‘dependent’) life stressors in late adolescence. Findings emphasize the need to be aware of social-emotional adversities that may occur in genetically vulnerable adolescents with ADHD symptoms in the transition into adulthood.     

Maternal Executive Functioning and Scaffolding in Families of Children with and without Parent-Reported ADHD

Parental scaffolding robustly predicts child developmental outcomes, including improved self-regulation and peer relationships and fewer externalizing behaviors. However, few studies have examined parental characteristics associated with a parent’s ability to scaffold. Executive functioning (EF) may be an important individual difference factor associated with maternal scaffolding that has yet to be examined empirically. Scaffolding may be particularly important for children with attention-deficit/hyperactivity disorder (ADHD) and disruptive behavior disorder (DBD) symptoms due to their core difficulties with inattention, disorganization, EF, and self-regulation, their need for greater parental structure, and higher-than-average rates of parental EF deficits. Yet, little research has examined child ADHD in relation to parental scaffolding. This cross-sectional study examined: (1) the association between maternal EF (as measured by the Hotel Test, Barkley’s Deficits in Executive Functioning Scale, and Digit Span) and observed scaffolding, (2) the association between parent-reported child ADHD/DBD symptoms and scaffolding, and (3) the interaction between child ADHD/DBD symptoms and maternal EF in predicting scaffolding. In a sample of 84 mothers and their 5–10 year-old biological children (62% male) with and without parent-reported ADHD, we found that maternal EF, as measured by Digit Span and the Hotel Test, predicted observed maternal scaffolding. However, child ADHD/DBD symptoms did not significantly predict maternal scaffolding controlling for child age, maternal education, and maternal EF, nor did the interaction of maternal EF and parent-reported child ADHD/DBD symptoms. Working memory and task shifting may be key components of parental EF that could be targeted in interventions to improve parental scaffolding.     

Psychopathic Personality Traits in Relation to Self-report Delinquency in Adolescence: Should We Mind About Interaction Effects?

The aim of the present study was to investigate if interaction effects among Youth Psychopathic Traits Inventory (YPI) Grandiose-Manipulative (GM), Callous-Unemotional (CU), and Impulsive-Irresponsible (II) may add significant information in predicting self-reports of juvenile delinquent behavior among adolescents. A sample of 558 Italian high school students were administered the YPI and the Self-Reports of Delinquency Scale (SRDS) in order to evaluate interaction effects among YPI GM, CU, and II dimensions. Results showed a significant effect for a three-way interaction among the three YPI dimensions in predicting the SRDS total score, β?=?.19, p?<?.01. In conclusion, the findings seem to underline that a three-factor model of psychopathy may help clinicians and researchers in predicting self-reported delinquency better than the individual factors.

A heterodox defense of the actualist higher-order thought theory

I defend the actualist higher-order thought theory against four objections. The first objection contends that the theory is circular. The second one contends that the theory is unable to account for the alleged epistemic position we are in with respect to our own conscious mental states. The third one contends that the theory is unable to account for the evidence we have for the proposition that all conscious mental states are represented. The fourth one contends that the theory does not accommodate the intimacy we have with our own conscious mental states. To some extent, my defense will be heterodox, in the sense that I will show that some objections are satisfactorily answerable even if we concede to the objectors a point that higher-order theorists do not seem to be willing to concede, that is, that the theory is the result of conceptual analysis.

     

Your Data are (Not) My Data: The Role of Social Value Orientation in Sharing Data About Others

The personal data consumers share with companies on a daily basis often also involves other people. However, prior research has focused almost exclusively on how consumers make decisions about their own data. In this research, we explore how consumers’ social value orientation impacts their decisions regarding data about others. In contrast to the notion of proselfs as “selfish” decision-makers, across four studies we find that proselfs are less likely than prosocials to share data about others with third parties. We show that this effect arises because proselfs feel less ownership over data they hold about others than prosocials, which in turn reduces their willingness to share it. Overall, this work contributes to literature on social value orientation as well as privacy decision-making and helps marketers and policy makers in designing interdependent privacy choice contexts.     

Adherence, body mass index, and depression in adults with type 2 diabetes: the mediational role of diabetes symptoms and self-efficacy.

OBJECTIVE: Evidence indicates that depression is linked to the development and worsening of diabetes, but the mechanisms underlying this link are not well understood. The authors examined the hypothesis that diabetes-related symptoms mediate the effect of both behavioral adherence and body mass index (BMI) on depression. In addition, they examined whether a prior finding that self-efficacy mediates the effect of behavioral adherence and BMI on depression would replicate with a larger sample size (W. P. Sacco, K. J. Wells, C. A. Vaughan, A. Friedman, S. Perez, & R. Morales, 2005). Also, the relative contributions of diabetes-related symptoms and self-efficacy to depression were evaluated. DESIGN AND PARTICIPANTS: Cross-sectional design involving adults diagnosed with Type 2 diabetes (N = 99). MAIN OUTCOME MEASURES: The primary outcome measure was depression (Patient Health Questionnaire: Nine Symptom Depression Checklist). Predictors of depression were diet and exercise adherence (Summary of Diabetes Self-Care Activities Questionnaire), diet and exercise self-efficacy (Multidimensional Diabetes Questionnaire), diabetes symptoms (Diabetes Symptom Checklist), and BMI (based on height and weight data from medical records). RESULTS: Path and mediation analyses indicated that adherence and BMI each contributed to depression indirectly, via their effects on self-efficacy and diabetes-related medical symptoms. CONCLUSION: Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms.     

Inclined Weight-Loaded Walking at Different Speeds: Pelvis-Shoulder Coordination,Trunk Movements and Cost of Transport

Although studied at level surface, the trunk kinematics and pelvis-shoulder coordination of incline walking are unknown. The aim of this study was to evaluate the speed effects on pelvis-shoulder coordination and trunk movement and the cost of transport (C) during unloaded and loaded (25% of body mass) 15% incline walking. We collected 3-dimensional kinematic and oxygen consumption data from 10 physically active young men. The movements were analyzed in the sagittal plane (inclination and range of trunk motion) and the transverse plane (range of shoulder and pelvic girdle motion and phase difference). The rotational amplitude of the shoulder girdle decreased with load at all speeds, and it was lower at the highest speeds. The rotational amplitude of the pelvic girdle did not change with the different speeds. The phase difference was greater at optimal speed (3 km.hr^?1, at the lowest C) in the loaded and the unloaded conditions. The trunk inclination was greater with load and increased with speed, whereas the range of trunk motion was lower in the loaded condition and decreased with increasing speed. In conclusion, the load decreased the range of girdles and trunk motion, and the pelvis-shoulder coordination seemed to be critical for the incline walking performance.
