Longitudinal direct and indirect pathways linking older sibling competence to the development of younger sibling competence

A 4-wave longitudinal model tested direct and indirect links between older sibling (OS; M = 11.7 years) and younger sibling (YS; M = 9.2 years) competence in 152 rural African American families. Data were collected at 1-year intervals. At each wave, different teachers assessed OS competence, YS competence, and YS self-regulation. Mothers reported their own psychological functioning; mothers and YSs reported parenting practices toward the YS. OS competence was stable across time and was linked with positive changes in mothers' psychological functioning from Wave 1 to Wave 2. Mothers' Wave 2 psychological functioning was associated with involved-supportive parenting of the YS at Wave 3. OS Wave 2 competence and Wave 3 parenting were indirectly linked with Wave 4 YS competence, through Wave 3 YS self-regulation. Structural equation modeling controlled for Wave 1 YS competence; thus, the model accounted for change in YS competence across 3 years.     

Self-reported reflective functioning and father–child interactions in a sample of fathers who have used intimate partner violence

Reflective functioning (RF) has been found to be associated with mother–child interactions, but less is known about the association of fathers’ self and child-focused RF and father–child relationships.  Fathers who have histories of intimate partner violence (IPV) are known to have poor RF, which may impact their father–child interactions.  The current study was designed to examine how types of RF are associated with father–child relationships.  Pretreatment assessments and recorded, coded father–child play interactions were used to examine associations among fathers’ history of adverse childhood experiences (ACES), RF and coded father-child play interactions in a sample of 47 fathers with a history of IPV use in the last 6 months with their coparent.  Fathers’ ACES and their child's mental states (CM) were associated with father-child dyadic play interactions.  Fathers with greater ACES and higher scores on CM had the most dyadic tension and constriction during play interactions.  Those with high ACES but low CM had scores similar to those with low ACES and low CM.  These results indicate that fathers who have used IPV and have a history of significant adversity may benefit from interventions to increase their child-focused RF and further improve their interactions with their children.     

Uncertainty and risk during the COVID-19 pandemic: A latent profile analysis

In the present study, we examine how subgroups of people are characterized by different profiles of uncertainty surrounding COVID-19, susceptibility, and recovery. Participants (N = 199) were U.S. residents recruited online for a longitudinal study during the summer of 2020. We first, identified groups using latent profile analysis (LPA) and then examined whether these profiles predicted differences in COVID-related risky and preventative behaviors. LPA identified five distinct profiles of people representing a combination of low and high uncertainty and low, moderate, and high risk perceptions. Results revealed that latent-profile group membership predicted intention to interact with others outside of the household, intention to engage in non-essential shopping, intention to attend an in-person religious gathering, intention to wear a mask in public, and self-reported physical distancing in the past week. Profile membership did not predict intentions to: dine out, go to the nail/hair salon, go to the gym, nor physically distance from others in the future, nor did it predict handwashing in the past week.     

Disorders of classificatory activity in aphasia

Two nonverbal tasks of classificatory activity ("class inclusion" and "class intersection") were administered to 46 aphasics, 28 normal controls, 19 nonaphasic left-brain-damaged and 17 right-hemisphere-damaged patients in order to study if aphasic patients are more impaired than nonaphasic brain-damaged patients on these two tasks of elementary logic and if a relationship exists within the aphasic patients between inability to perform the tasks of classifiactory activity and impairment of the semantic-lexical level of integration of language. Results were for the most part in line with expectations because aphasics scored worse than normal controls and nonaphasic brain-damaged patients (even if the difference reached the level of statistical significance only on the test of "class intersection") and within the aphasic patients the worst results were obtained by subjects presenting clear signs of semantic-lexical disintegration.     

Comparison of Informed Consent Preferences for Multiplex Genetic Carrier Screening among a Diverse Population

Multiplex genetic carrier screening is increasingly being integrated into reproductive care. Obtaining informed consent becomes more challenging as the number of screened conditions increases. Implementing a model of generic informed consent may facilitate informed decision-making. Current Wayne State University students and staff were invited to complete a web-based survey by blast email solicitation. Participants were asked to determine which of two generic informed consent scenarios they preferred: a brief versus a detailed consent. They were asked to rank the importance of different informational components in making an informed decision and to provide demographic information. Comparisons between informational preferences, demographic variables and scenario preferences were made. Six hundred ninety three participants completed the survey. When evaluating these generic consents, the majority preferred the more detailed consent (74.5 %), and agreed that it provided enough information to make an informed decision (89.5 %). Those who thought it would be more important to know the severity of the conditions being screened (p?=?.002) and range of symptoms (p?=?.000) were more likely to prefer the more detailed consent. There were no significant associations between scenario preferences and demographic variables. A generic consent was perceived to provide sufficient information for informed decision making regarding multiplex carrier screening with most preferring a more detailed version of the consent. Individual attitudes rather than demographic variables influenced preferences regarding the amount of information that should be included in the generic consent. The findings have implications for how clinicians approach providing tailored informed consent.     

Determinants of cognitive outcomes of perinatal and childhood stroke: A review

Our understanding of cognitive and behavioral outcomes of perinatal and childhood stroke is rapidly evolving. A current understanding of cognitive outcomes following pediatric stroke can inform prognosis and direct interventions and our understanding of plasticity in the developing brain. However, our understanding of these outcomes has been hampered by the notable heterogeneity that exists amongst the pediatric stroke population, as the influences of various demographic, cognitive, neurological, etiological, and psychosocial variables preclude broad generalizations about outcomes in any one cognitive domain. We therefore aimed to conduct a detailed overview of the published literature regarding the effects of age at stroke, time since stroke, sex, etiology, lesion characteristics (i.e., location, laterality, volume), neurologic impairment, and seizures on cognitive outcomes following pediatric stroke. A key theme arising from this review is the importance of interactive effects among variables on cognitive outcomes following pediatric stroke. Interactions particularly of note include the following: (a) age at Stroke x Lesion Location; (b) Lesion Characteristics (i.e., volume, location) x Neurologic Impairment; (c) Lesion Volume x Time Since Stroke; (d) Sex x Lesion Laterality; and (e) Seizures x Time Since Stroke. Further, it appears that these relationships do not always apply uniformly across cognitive domains but, rather, are contingent upon the cognitive ability in question. Implications for future research directions are discussed.     

The effect of semantic context on prospective memory performance

The current study provides evidence for spontaneous processing in prospective memory (PM) or memory for intentions. Discrepancy-plus-search is the spontaneous processing of PM cues via disruptions in processing fluency of ongoing task items. We tested whether this mechanism can be demonstrated in an ongoing rating task with a dominant semantic context. Ongoing task items were manipulated such that the PM cues were members of a semantic category (i.e., Body Parts) that was congruent or discrepant with the dominant semantic category in the ongoing task. Results showed that participants correctly responded to more PM cues when there was a category discrepancy between the PM cues and ongoing task items. Moreover, participants' identification of PM cues was accompanied by faster ongoing task reaction times when PM cues were discrepant with ongoing task items than when they were congruent. These results suggest that a discrepancy-plus-search process supports PM retrieval in certain contexts, and that some discrepancy-plus-search mechanisms may result from the violation of processing expectations within a semantic context.     

The Contribution of Hope and Affectivity to Diabetes-Related Disability: An Exploratory Study

This study examined the relationships of the dispositional variables of hope, positive affectivity (PA), and negative affectivity (NA) with disease status and illness-related psychosocial functioning in a sample of 45 young adults with insulin-dependent diabetes mellitus (IDDM). Canonical analyses revealed one significant canonical function between the dispositional and psychosocial outcome variables. Primary contributors to the relationship were higher NA and lower PA and maladaptive emotional behavior. A linear multiple regression analysis using hope and affectivity as predictors failed to account for a significant proportion of variance in objective disease status as measured by hemoglobin A _1C (HbA_1C). The results support previous findings that affectivity may relate to self-reported, disease-related outcome, but not necessarily to objective measures of health status. Future studies of adaptation to chronic illness should consider including measures of illness-related behaviors (e.g., adherence), as well as subjective and objective measures of health status.
