Modeling effects of risk and social distance on vaccination choice

Despite vaccines' consistently demonstrated effectiveness, vaccination rates remain suboptimal due to vaccine refusal. Low vaccination rates are particularly problematic for individuals who cannot be vaccinated for medical reasons and thus must rely on herd immunity (i.e., protection of vulnerable individuals due to the high rate of vaccination of other—often socially distant—individuals). The current study uses a novel decision‐making task to examine how three variables impacted participants' highest acceptable probability of side effects to their children: 1) the severity of the side effects their children experience, 2) the social distance to the beneficiary of the vaccination, and 3) the probability that the vaccine will prevent disease for that designated beneficiary. Participants' willingness to risk potential side effects of vaccination systematically decreased as the 1) effectiveness of the vaccination decreased, 2) the beneficiary of the vaccination became more socially distant, and 3) the severity of side effects increased. These data were well‐described by behavioral economic models used to examine the discounting of other health behavior.     

A Method for Universal Screening of Elementary School Students: Development of the Social Challenges Screening Questionnaire

Schools regularly screen students for hearing and vision impairments because they present impediments to academic progress. For the same reason, schools should consider adding a universal screening for social challenges, which may also impede the learning process. This study reports on the development of the Social Challenges Screening Questionnaire (SCSQ), an efficient teacher-report screening questionnaire that identifies students with challenges who may benefit from a psychological evaluation. Further, the questionnaire may help identify students with Autism Spectrum Disorder who were previously undiagnosed. The SCSQ was administered to 549 general education students in the third and fourth grades. Internal consistency was.85. A smaller sample of students (n = 50) was selected for additional follow up assessment using the Social Responsiveness Questionnaire, Second Edition. Scores on the two instruments were strongly correlated (r =.87, p <.01), and sensitivity (.94) and specificity (.88) indicate the SCSQ can efficiently detect students with social challenges in need of a formal evaluation.     

Longitudinal Impact of a Family Critical Time Intervention on Children in High-Risk Families Experiencing Homelessness: A Randomized Trial

A randomized trial compared effects of a Family Critical Time Intervention (FCTI) to usual care for children in 200 newly homeless families in which mothers had diagnosable mental illness or substance problems. Adapted from an evidence‐based practice to prevent chronic homelessness for adults with mental illnesses, FCTI combines housing and structured, time‐limited case management to connect families leaving shelter with community services. Families were followed at five time points over 24 months. Data on 311 children—99 ages 1.5–5 years, 113 ages 6–10 years, and 99 ages 11–16 years—included mother‐, teacher‐, and child‐reports of mental health, school experiences, and psychosocial well‐being. Analyses used hierarchical linear modeling to investigate intervention effects and changes in child functioning over time. Referral to FCTI reduced internalizing and externalizing problems in preschool‐aged children and externalizing for adolescents 11–16. The intervention led to declines in self‐reported school troubles for children 6–10 and 11–16. Both experimental and control children in all age groups showed reductions in symptoms over time. Although experimental results were scattered, they suggest that FCTI has the potential to improve mental health and school outcomes for children experiencing homelessness.     

Meta-Analysis of the Effects of Peer-Administered Psychosocial Interventions on Symptoms of Depression

Many community mental health centers have implemented peer treatment models that employ recovered former clients as cost‐efficient adjunct providers. The effectiveness of these and other peer‐administered interventions (PAIs) for treating depression symptoms has not been well‐established. The current study is a meta‐analysis of PAIs’ effects on depression symptoms. Twenty‐three eligible studies were identified. Study characteristics were coded by multiple raters, random‐effects models were used to compare mean effect sizes, and mixed‐effects models were used to test for moderation. PAIs produced significant pre‐post reductions in depression symptoms (d = .5043 [95 % CI .3675–.6412]). In direct comparisons, PAIs performed as well as non‐peer‐administered interventions (.0848 [?.1455–.3151]), and significantly better than no‐treatment conditions (.2011 [.0104–.3918]). PAIs that involved a professional in a secondary treatment role were significantly less effective than those that were purely peer‐administered, and educational/skills‐based PAIs produced better outcomes than those that were mainly supportive. Follow‐up data, when available, indicated that PAIs’ benefits were maintained. PAIs reduce depression symptoms and warrant further study. The clinical significance of PAIs’ benefits, and whether they are better suited as stand‐alone or adjunct treatments, remain to be established. Implications for the roles of mental health professionals are discussed.     

Mobile Internet Testing: An analysis of equivalence,individual differences,and reactions

Mobile internet testing (MIT) is the latest cost effective technological push in employment testing. The ability to access assessments via the internet using mobile devices provides increased speed and convenience for both administrators and respondents. In this article, we examine the equivalence of MIT compared with testing on personal computers (PCs) and whether attitudes and other individual differences influence responses and reactions to MIT. Results demonstrated equivalence for a supervisory situational judgment test across testing modes, but not for a cognitive ability test. Significant relationships were found between anxiety and both performance and reactions to mobile assessment. Respondents also reported significantly more positive reactions when tested on a PC versus a mobile device. Future research and practical implications are discussed.     

A bilateral advantage for maintaining objects in visual short term memory

Research has shown that attentional pre-cues can subsequently influence the transfer of information into visual short term memory (VSTM) (Schmidt, B., Vogel, E., Woodman, G., & Luck, S. (2002). Voluntary and automatic attentional control of visual working memory. Perception & Psychophysics, 64(5), 754–763). However, studies also suggest that those effects are constrained by the hemifield alignment of the pre-cues (Holt, J. L., & Delvenne, J.-F. (2014). A bilateral advantage in controlling access to visual short-term memory. Experimental Psychology, 61(2), 127–133), revealing better recall when distributed across hemifields relative to within a single hemifield (otherwise known as a bilateral field advantage). By manipulating the duration of the retention interval in a colour change detection task (1 s, 3 s), we investigated whether selective pre-cues can also influence how information is later maintained in VSTM. The results revealed that the pre-cues influenced the maintenance of the colours in VSTM, promoting consistent performance across retention intervals (Experiments 1 & 4). However, those effects were only shown when the pre-cues were directed to stimuli displayed across hemifields relative to stimuli within a single hemifield. Importantly, the results were not replicated when participants were required to memorise colours (Experiment 2) or locations (Experiment 3) in the absence of spatial pre-cues. Those findings strongly suggest that attentional pre-cues have a strong influence on both the transfer of information in VSTM and its subsequent maintenance, allowing bilateral items to better survive decay.     

The effectiveness of three strategies to reduce the influence of bias in evaluations of female leaders

This study tests the effectiveness of three strategies [structured free recall (SFR), source monitoring, and error management] to reduce the impact of raters' stereotypes on evaluations of female leaders. Results reveal several three‐way interactions indicating that that the strategies became more effective as raters' implicit bias decreased. Findings show that the source monitoring and SFR methods were more effective than the error management strategy. The results have implications for improving opportunities for women to advance through the leadership ranks. This study adds to the literature by comparing multiple strategies to reduce the influence of individuals' biases in evaluations of women in leadership positions and revealing the importance of considering raters' implicit gender biases in evaluations.
