Ethical Considerations for Assessing Parent Mental Health during Child Assessment Services

Parents play an integral role in the mental health service provision of children and adolescents, and they can have significant effects on the outcomes of youth. A growing body of research has linked parents’ own mental health status to numerous outcomes for their children, and recent guidelines have emerged recommending the assessment of parent psychopathology when treating child patients. However, these recommendations present a range of ethical considerations. Mental health professionals must determine if the assessment of a parent is empirically supported and that an assessment procedure appropriate for parents can be feasibly implemented. They must also respect the autonomy and confidentiality of parents while ensuring that assessment findings can be translated to meaningful benefits for child patients. This article details and discusses each of these concerns within the context of the relevant principles and standards of the 2016 American Psychological Association’s Code of Ethics. Further, it provides guidelines, relevant clinical examples, and an applied model for mental health professionals to consider the ethical implications of assessing parent mental health when serving child patients.     

Bidirectional,Longitudinal Associations Between Math Ability and Approximate Number System Precision in Childhood

Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math ability longitudinally in 3- to 5-year-old children. Children were observed at three time points roughly six months apart; they completed a nonsymbolic numerical comparison task that measured ANS precision and a standardized math assessment. A series of cross-lagged panel models was then estimated to explore the associations between ANS precision and math ability over time. Bidirectional associations between ANS precision and math ability emerged: Early ANS precision was related to children’s later math skills, and early math ability also significantly predicted children’s later ANS precision. Evidence for mutual enhancement over time between the ANS and symbolic math ability adds to our growing understanding of the ANS and how the ANS and math knowledge interact.     

Daily School Context of Adolescents' Single Best Friendship and Adjustment

Research on adolescent best friendships typically focuses on school-based friendships, ignoring important differences between classroom-based and out-of-school friendships. With data from 156 ninth-grade students, many of whom named more than 1 best friend across the 14-day period, the authors examined associations between the daily school context of one's best friendship and adjustment. Benefits of in-grade best friendships were found in academic engagement when a composite was assessed across the 2-week period. Daily findings were more complex and were different between weekends and school days. Out-of-grade best friends were named more frequently on weekends, and on weekend days in which they named an out-of-school best friend participants spent more time with that friend but felt like less of a good student. Implications for our understanding of friendship context and for the measurement of friendship itself are discussed.     

She Got Herself There: Narrative Resistance in the Drug Discourse of Strippers

There has been ample literature on strip clubs regarding interactions between strippers and patrons, power and social control, and how dancers manage their identities as stigmatized workers. Few studies have explored how dancers grapple with their doubly deviant identities as dancers and as drug and alcohol users. Through interviews and fieldwork, I explore how dancers frame their drug use. At times, dancers stigmatize other dancers by using damaging stereotypes to “other” sister workers for drug abuse. At other times, strippers do not malign other dancers for drug and alcohol use. Instrumental or recreational drug use is relatively unstigmatized.     

Discomfort and avoidance of touch: new insights on the emotional deficits of social anxiety

Physical touch is central to the emotional intimacy that separates romantic relationships from other social contexts. In this study of 256 adults (128 heterosexual couples, mean relationship length?=?20.5 months), we examined whether individual differences in social anxiety influenced comfort with and avoidance of physical touch. Because of prior work on sex difference in touch use, touch comfort, and social anxiety symptoms and impairment, we explored sex-specific findings. We found evidence that women with greater social anxiety were less comfortable with touch and more avoidant of touch in same-sex friendships. Additionally, a woman’s social anxiety had a bigger effect on a man’s comfort with touch and avoidance of touch in the romantic relationship than a man’s social anxiety had on the woman’s endorsement of touch-related problems. These effects were uninfluenced by the length of romantic relationships. Touch is a neglected emotional experience that offers new insights into the difficulties of individuals suffering from social anxiety problems, and their romantic partners.     

The Effects of Expertise on the Hindsight Bias

We present data from three experiments examining the effects of objective and subjective expertise on the hindsight bias. In Experiment 1, participants read an essay about baseball or dogs and then answered questions about the baseball essay to the best of their ability, as if they had not read the essay, or to the best of their ability, although they read about dogs. Participants also completed a quiz about baseball rules and terminology, which was an objective measure of expertise. Results demonstrated that as participants' baseball expertise increased, their inability to act as if they never read the essay also increased; expertise exacerbated the hindsight bias. To test the effects of subjective expertise on hindsight bias and investigate factors underlying the relationship, participants in Experiment 2 ranked five topics in order of expertise and gave feeling‐of‐knowing (FOK) ratings for questions from these topics. Foresight participants then saw each question again and answered the questions; hindsight participants saw the questions and answers and gave the probability they would have known the answers had they not been provided. Hindsight bias increased with subjective expertise as did average FOK ratings. In Experiment 3, we experimentally manipulated perceived expertise but found that neither average FOK ratings nor hindsight bias was affected by experimentally induced expertise. Taken together, the results demonstrate that expertise exacerbates both objective and subjective hindsight bias but that an FOK, which likely exists only when expertise is naturally acquired, is necessary to engender the detrimental effect of expertise on the hindsight bias.

Attempts to prime intellectual virtues for understanding of science: Failures to inspire intellectual effort

Strategies for effectively communicating scientific findings to the public are an important and growing area of study. Recognizing that some complex subjects require recipients of information to take a more active role in constructing an understanding, we sought to determine whether it was possible to increase subjects’ intellectual effort via “priming” methodologies. In particular, we asked whether subconsciously priming “intellectual virtues” (IVs), such as curiosity, perseverance, patience, and diligence might improve participants’ effort and performance on various cognitive tasks. In the first experiment, we found no significant differences in either effort or understanding between IV-primed and neutrally-primed individuals across two different priming techniques. The second experiment measured the effect of IV-priming on intellectual effort in simpler, shorter-duration puzzles and exploration activities; here, we observed an effect, but given its low strength and short duration, we do not believe that priming of IVs is a promising strategy for science communication.     

Moderating Effects of Mathematics Anxiety on the Effectiveness of Explicit Timing

Explicit timing is an empirically validated intervention to increase problem completion rates by exposing individuals to a stopwatch and explicitly telling them of the time limit for the assignment. Though explicit timing has proven to be effective for groups of students, some students may not respond well to explicit timing based on factors such as mathematics anxiety. The present study examined the effects of explicit timing on mathematics performance for 81 fourth and fifth graders with differing levels of mathematics anxiety. Students completed more digits correct during explicit timing as compared to baseline and control. Additionally, results indicated there was a significant linear relationship between mathematics anxiety and mathematics performance. Students with low and medium mathematics anxiety completed more digits correct with higher accuracy than students with high mathematics anxiety. Lastly, digits correct and accuracy remained consistent during baseline, control, and explicit timing when condition and anxiety level were both considered. Educational professionals must be cognizant not only of academic variables impacting students learning, but also mental health variables, such as mathematics anxiety, in order to provide a comprehensive treatment package capable of ameliorating academic difficulties.     

Associations between childhood adversity and daily suppression and avoidance in response to stress in adulthood: can neurobiological sensitivity help explain this relationship?

Background and objectives: Although it has been postulated that psychological responses to stress in adulthood are grounded in childhood experiences in the family environment, evidence has been inconsistent. This study tested whether two putative measures of neurobiological sensitivity (vagal flexibility and attentional capacity) moderated the relation between women’s reported exposure to a risky childhood environment and current engagement in suppressive or avoidant coping in response to daily stress.

Design and methods: Adult women (N?=?158) recruited for a study of stress, coping, and aging reported on early adversity (EA) in their childhood family environment and completed a week-long daily diary in which they described their most stressful event of the day and indicated the degree to which they used suppression or avoidance in response to that event. In addition, women completed a visual tracking task during which heart rate variability and attentional capacity were assessed.

Results: Multilevel mixed modeling analyses revealed that greater EA predicted greater suppression and avoidance only among women with higher attentional capacity. Similarly, greater EA predicted greater use of suppression, but only among women with greater vagal flexibility.

Conclusion: Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.
