The formative role of social class in the United States has long been a focus of fields such as economics, history, and political science. Yet, little psychological theory or data are available to guide our understanding of what messages regarding social class are transmitted within and across generations and how those transmissions are most likely to occur. As a launching point for such work, we focus this initial contextual and largely theoretical review on parent-adolescent socialization of social class in low-income, White families of adolescents in particular. To this end, our goal was to raise potential hypotheses about the implicit and explicit ways that White low-income parents may shape adolescent views of class, as well as the meaning and implications of status socialization for adolescent health and well-being.

UNLABELLED:The risk for diabetes risk is significantly elevated in persons who are older, overweight and have serious mental illness. However, primary care practitioners (PCP) tend to underestimate this risk. Although there are few opportunities for early detection of diabetes, blood exuded during routine oral exams in dental settings can be used to assess glycated hemoglobin (HbA1c) levels. The current study sought to understand how primary care practitioners would react to patients who screened positive for elevated HbA1c, how they estimated risk, and whether they provided treatment recommendations or counseling. METHOD/UNASSIGNED:Semi-structured telephone interviews were conducted on 61 subjects three months after demonstrating elevated HbA1c levels from dental screenings. Data were transcribed and analyzed using content analysis. RESULTS/UNASSIGNED:Qualitative analyses revealed four themes according to patients: (1) "Being told I needed to make lifestyle changes" (41%); (2) Realizing I needed a new health care provider or medication change" (10%); (3) "Being told of the need for monitoring but no counseling/treatment change" (16%); and (4) "Being told everything is fine and there is nothing to worry about" (31%). CONCLUSIONS/UNASSIGNED:Only half of the 61 cases reporting elevated HbA1C levels at screening experienced their PCP's as responding with counseling or medication changes. Almost a third of cases perceived that their PCP's dismissed the results, making no recommendations, and the rest perceived no counseling or interventions being proposed. Based on subjects' perceptions of their PCP's responses to their elevated HbA1c values, the impact of this intervention is substantially reduced over expectations.

Interpreting iconic gestures can be challenging for children. Here, we explore the features and functions of iconic gestures that make them more challenging for young children to interpret than instrumental actions. In Study 1, we show that 2.5-year-olds are able to glean size information from handshape in a simple gesture, although their performance is significantly worse than 4-year-olds'. Studies 2 to 4 explore the boundary conditions of 2.5-year-olds' gesture understanding. In Study 2, 2.5-year-old children have an easier time interpreting size information in hands that reach than in hands that gesture. In Study 3, we tease apart the perceptual features and functional objectives of reaches and gestures. We created a context in which an action has the perceptual features of a reach (extending the hand toward an object) but serves the function of a gesture (the object is behind a barrier and not obtainable; the hand thus functions to represent, rather than reach for, the object). In this context, children struggle to interpret size information in the hand, suggesting that gesture's representational function (rather than its perceptual features) is what makes it hard for young children to interpret. A distance control (Study 4) in which a person holds a box in gesture space (close to the body) demonstrates that children's difficulty interpreting static gesture cannot be attributed to the physical distance between a gesture and its referent. Together, these studies provide evidence that children's struggle to interpret iconic gesture may stem from its status as representational action. (PsycINFO Database Record

Chronic pain (CP) and opioid use disorder (OUD) remain challenging complex public health concerns. This is an updated review on the relationship between CP and OUD and the use of stepped care models for assessment and management of this vulnerable population. A literature search was conducted from 2008 to the present in PubMed, Embase, and PsycInfo using the terms pain or chronic pain and opioid-related disorders, opiate, methadone, buprenorphine, naltrexone, opioid abuse, opioid misuse, opioid dependen*, heroin addict, heroin abuse, heroin misuse, heroin dependen*, or analgesic opioids, and stepped care, integrated services, multidisciplinary treatment, or reinforcement-based treatment. Evidenced-based data exists on the feasibility, implementation, and efficacy of stepped care models in primary care settings for the management of CP and opioid use. Although these studies did not enroll participants with OUD, they included a sub-set of patients at risk for the development of OUD. There remains a dearth of treatment options for those with comorbid CP and OUD. Future research is needed to explore the aetiology and impact of CP and OUD, and greater emphasis is needed to improve access to comprehensive pain and substance use programmes for high-risk individuals.

Background:The declining transition rate to psychotic disorder and the increasing rate of nonpsychotic poor outcomes among subjects at clinical high risk (CHR) for psychosis have increased the need for biomarkers to predict remission regardless of transition. This study investigated whether mismatch negativity (MMN) predicts the prognosis of CHR individuals during a 6-year follow-up period. Methods:A total of 47 healthy control (HC) subjects and 48 subjects at CHR for psychosis participated in the MMN assessment. The clinical statuses of the CHR subjects were examined at baseline and regularly for up to 6 years. The CHR subjects were divided into remitter and nonremitter groups, and the baseline MMN amplitudes and latencies were compared across the remitter, nonremitter, and HC groups. Regression analyses were performed to identify the predictive factors of remission, the improvement of attenuated positive symptoms, and functional recovery. Results:CHR nonremitters showed reduced MMN amplitudes at baseline compared to CHR remitters and HC subjects. A logistic regression analysis revealed that the baseline MMN amplitude at the frontal electrode site was the only significant predictor of remission. In a multiple regression analysis, the MMN amplitude, antipsychotic use, and years of education predicted an improvement in attenuated positive symptoms. The MMN amplitude at baseline predicted functional recovery. Conclusions:These results suggest that MMN is a putative predictor of prognosis regardless of the transition to psychotic disorder in subjects at CHR. Early prognosis prediction and the provision of appropriate interventions based on the initial CHR status might be aided using MMN.

OBJECTIVE:Early-onset obsessive-compulsive disorder (EOCD) and late-onset obsessive-compulsive disorder (LOCD) are distinct subtypes of obsessive-compulsive disorder (OCD). OCD patients are treated with serotonin reuptake inhibitors, but the difference in serotonin transporter (SERT) availability between medicated EOCD and LOCD is unexplored yet. METHODS:C]DASB positron emission tomography scans during maintenance therapy with escitalopram, and their plasma concentration of escitalopram was measured simultaneously with the scan. Then, the drug-free binding potential of SERT was calculated by pharmacokinetic-pharmacodynamic modelling. RESULTS:In comparison with LOCD patients, SERT availability was significantly higher in the putamen of EOCD patients (U = 4, p = .026), but not in the caudate nucleus (U = 14, p = .589), thalamus (U = 16, p = .818), and dorsal raphe nucleus (U = 7, p = .093). Binding potential of putamen showed a negative correlation (r = -.580, p = .048) with age of onset of the disease, but not with the Yale-Brown Obsessive Compulsive Scale scores. CONCLUSIONS:These findings indicate that the earlier the age of onset of OCD, the less serotonergic pathology there is and that this difference remains even after long-term serotonin reuptake inhibitor treatment. Clinically, it might suggest that nonserotonergic treatments would be a better option for EOCD patients.
