Age Neutrality of Categorically and Dimensionally Measured DSM–5 Section II Personality Disorder Symptoms

Studies on the face validity of DSM–5 Section II categorical personality disorder (PD) symptoms indicate a bias against older adults. To extend these results, this article explores whether categorically and dimensionally scored PD symptoms of DSM–5 Section II, as measured in the Assessment of DSM–IV Personality Disorders (ADP–IV; Schotte & de Doncker, 1994), corroborate potential age bias across younger (aged 18–34), middle-aged (35–59 years), and older adults (aged 60–75). Differential item functioning (DIF) analyses, following a classical test theory approach, showed that 2 of the 79 symptoms were measured differently across 3 age groups when categorically assessed, and 4 when dimensionally measured. Nevertheless, subsequent differential test functioning analyses supported a low aggregated impact of DIF on the dimensional scales, justifying mean-level comparisons across age groups. Generalizability of the results is discussed in light of methodological issues concerning the research of age neutrality of PD symptoms, including the employed measurement instrument, PD symptom measurement approach, and sample and age range used to describe older adults.     

The Scientist and the Artist: adaptive dissociation within the HIV-positive population

This paper reports on the findings of two independent qualitative studies which were conducted with HIV-positive cohort over a period of 2010–2012. Although the original studies used different qualitative designs (IPA and Grounded Theory), the authors have nevertheless sought to explore the combined utility of their findings by using a broad stance of phenomenological enquiry. The authors argue that evidence of a particular dissociative pattern in their accounts of an HIV-related experience is present in the contributors' narrative. Dissociation in this context occurred not in personality but between different or discrete mental faculties such as memory, emotions, perceptions and thought. It was suggested that it serves adaptive function and therefore could be utilised in clinical work when appropriate.     

The mental health of children of migrant workers in Beijing: The protective role of public school attendance

The present study aims to understand the mental health status of an understudied group of migrant children – children of migrant workers in China. A total of 1,466 children from Beijing participated in the study that compared migrant children (n = 1,019) to their local peers (n = 447) in public and private school settings. Results showed that overall, migrant children reported more internalizing and externalizing mental health problems and lower life satisfaction than local peers. However, public school attendance served as a protective factor for migrant children's mental health. The mental health status of migrant children attending public schools, including externalizing problems as well as friend and school satisfaction, was not different from local children. In addition, our data indicates that the protective effect of public school attendance for migrant children may be even more salient among girls than boys, and for younger children than older children.     

Adolescent mice,unlike adults,consume more alcohol in the presence of peers than alone

One hallmark of adolescent risk‐taking is that it typically occurs when adolescents are with peers. It has been hypothesized that the presence of peers primes a reward‐sensitive motivational state that overwhelms adolescents' immature capacity for inhibitory control. We examined this hypothesis using a rodent model. A sample of mice were raised in same‐sex triads and were tested for alcohol consumption either as juveniles or as adults, with half in each age group tested alone and half tested with their cagemates. The presence of ‘peers’ increased alcohol consumption among adolescent mice, but not adults. The peer effect on human adolescent reward‐seeking may reflect a hard‐wired, evolutionarily conserved process through which the presence of agemates increases individuals' sensitivity to potential rewards in their immediate environment.     

The Cross-Temporal Associations between Rumination Subtypes and Substance Use in Adolescence: Exploring the Moderating Role of Gender

Several studies have linked rumination to substance use. However, only one study thus far has focused on the differential associations between the subtypes of rumination (brooding and reflection) and substance use. This previous study was cross-sectional in nature, so less is known about how these variables are related across time. To address this issue, the present three-wave longitudinal study investigated the cross-temporal associations between subtypes of rumination, alcohol consumption, drug consumption and substance use problems, using cross-lagged path analyses. In addition, the study investigated whether the cross-lagged paths of interest were moderated by gender. The sample consisted of 309 adolescents (62.1 % boys) between the ages of 13 to 20 years old (M _age at T1?=?16.82 years, SD?=?1.32). Results indicated that substance use problems predicted increases in levels of brooding and reflection over time. These effects were moderated by gender so that substance use problems only predicted increases in levels of brooding and reflection in girls. In contrast to our expectations, higher levels of brooding predicted a decrease in alcohol consumption over time, and this effect was not moderated by gender. Cross-lagged analyses also showed that alcohol consumption predicted an increase in substance use problems. All results emerged independently of depressive symptoms. The findings of the present study add to the growing body of literature on the associations between rumination subtypes and substance use in adolescence, and highlight the importance of using longitudinal designs to address the issue of directionality.     

The execution of planned detours by spider‐eating predators

Many spiders from the salticid subfamily Spartaeinae specialize at preying on other spiders and they adopt complex strategies when targeting these dangerous prey. We tested 15 of these spider‐eating spartaeine species for the capacity to plan detours ahead of time. Each trial began with the test subject on top of a tower from which it could view two boxes: one containing prey and the other not containing prey. The distance between the tower and the boxes was too far to reach by leaping and the tower sat on a platform surrounded by water. As the species studied are known to avoid water, the only way they could reach the prey without getting wet was by taking one of two circuitous walkways from the platform: one leading to the prey (‘correct’) and one not leading to the prey (‘incorrect’). After leaving the tower, the test subject could not see the prey and sometimes it had to walk past the incorrect walkway before reaching the correct walkway. Yet all 15 species chose the correct walkway significantly more often than the incorrect walkway. We propose that these findings exemplify genuine cognition based on representation.
