I get High with a Little Help from my Friends (and Family): Close Relationships, Distress Tolerance, and Risk-Taking in Adolescence
Despite substantial efforts to educate adolescents about the consequences of their risky decisions, adolescent risk behavior remains a significant social and public health problem. The goal of this research was to examine the role of individual and contextual predictors of adolescent health risk behavior and risk-taking measured in the laboratory. Specifically, I examined parent-adolescent relationships and friendships as two contextual predictors of risk, and I measured adolescent distress tolerance as an individual predictor of risk behavior in a longitudinal study of adolescents and their families. In Aim 1, I used a variable-centered approach to examine concurrent and prospective predictors of adolescent risk-taking. In Aim 2, I took a person-oriented statistical approach to the study of adolescent risk-taking by examining whether there are particular groups of adolescents with particular relationship characteristics who were most likely to engage in risky behavior, and whether these groups of adolescents would be more likely to take risks if they had low distress tolerance. Aim 1 analyses revealed that adolescents were most likely to engage in health risk behaviors when they had negative parent-adolescent relationships or positive friendships, but distress tolerance was unrelated to risk-taking. None of the predictors was related to laboratory risk behavior. Aim 2 analyses revealed that the influence of adolescents' relationships on their risk-taking behaviors depended on their ability to tolerate and manage their emotions. Among adolescents with high levels of friendship conflict, distress tolerance served as a protective factor against health risk behavior. Among high distress tolerant adolescents, those who had high parent-adolescent conflict engaged in greater risk-taking than adolescents who had high friendship conflict. Across all analyses, none of the predictors accounted for Time 2 risk behavior after accounting for Time 1 risk-taking in the models. Overall, these findings suggest that adolescents' relationship experiences and distress tolerance relate to risk-taking behaviors, even at an age when adolescents are engaging in relatively low levels of risk behavior. Future research should continue investigating predictors of risk behavior across multiple levels of analysis, with an emphasis on biological, individual, relational, and environmental factors that contribute to risk-taking
Experience of Violence and Socioeconomic Position in South Africa: A National Study
BACKGROUND: Violence is a leading cause of morbidity and mortality in South Africa and needs to be researched from a public health perspective. Typically in violence research, socioeconomic position is used in the analysis to control for confounding. Social epidemiology approaches this variable as a primary determinant of interest and is used in this research to better understand the aetiology of violence in South Africa. We hypothesised that measures of socioeconomic position (employment, education and household wealth) would be inversely related to violence at the individual and household levels. METHODOLOGY/PRINCIPAL FINDINGS: Data came from the1998 South African Demographic and Health Survey (SADHS). Measures of socioeconomic position used were employment, education and household wealth. Eighty-eight people (0.2%) received treatment for a violent injury in the previous 30 days and 103 households (0.9%) experienced a violent death in the previous year. Risk factors for violence at the individual level included employment (41% of those who experienced violence were employed vs. 27% of those who did not, p = 0.02), and education (those who experienced violence had on average, one year more education than those who did not, p = 0.04). Belonging to a household in the wealthiest quintile was protective against violence (OR: 0.32; 95% CI: 0.12-0.89). In contrast, at the household level all three measures of socioeconomic position were protective against the experience of a violent death. The only association to persist in the multivariate analysis was that between the wealth of the household and violence at the individual level. Conclusions/Significance Our hypothesis was supported if household wealth was used as the measure of socioeconomic position at the individual level. While more research is needed to inform the conflicting results observed between the individual and household levels, this analysis has begun to identify the disparities across the socioeconomic structure with respect to violent outcomes
Conflict at home and problems with peers: Family-peer linkages and the role of adolescent depressive symptoms and gender
Peer relationships have a significant impact on developmental outcomes throughout the lifespan. One variable that has been identified extensively as a contributor to peer outcomes is children's family environment. In the present investigation, I examine the relation between adolescents' family environment and peer relationships. Specifically, I study how family conflict, including both parent-child conflict and marital conflict, is linked to social acceptance and social behavior. I examine whether adolescents' depressive symptoms act as a mediator of the links between family conflict and social acceptance and behavior. Finally, I examine the moderating role of gender
Hypervigilance to rejecting stimuli in high rejection sensitive individuals : behavioral and neurocognitive evidence
This research was supported by a grant from the National Institute of Child Health and Human Development (HD17899) and a NARSAD Distinguished Investigator Award to Nathan A. Fox and by DA027365 and HD076563 to Katherine B. Ehrlich. Date of acceptance: 10/04/2015Individuals who are high in rejection sensitivity are vigilant toward social cues that signal rejection, and they exhibit attention biases towards information that confirms expectations of rejection. Little is known, however, about the neural correlates of rejection sensitivity. The present study examined whether rejection sensitivity is associated with individuals’ neural responses to rejection-relevant information. Female participants, classified as high or average in rejection sensitivity, completed a modified dot-probe task in which a neutral face was paired with either another neutral face or a gaze-averted (“rejecting”) face while EEG was collected and ERP components were computed. Behavioral results indicated that average rejection sensitive participants showed an attention bias away from rejecting faces, while high rejection sensitive participants were equally vigilant to neutral and rejecting faces. High rejection sensitivity was associated with ERP components signaling elevated attention and arousal to faces. These findings suggest that rejection sensitivity shapes behavioral and neurocognitive responses to faces.PostprintPeer reviewe
Functioning and Vision-Related Quality of Life in Severe Peripheral Field Loss due to Retinitis Pigmentosa: A Qualitative Study
Vision impairment and blindness are associated with disability and decreased social participation and independence. While vision rehabilitation may improve patients’ functional abilities, there is scarce data regarding the effectiveness of rehabilitation for patients with severe peripheral field loss (PFL). In order to evaluate rehabilitation strategies for individuals with severe PFL, a valid and reliable instrument to measure vision-dependent functioning and vision-related quality of life is needed. Accordingly, this qualitative study was the first phase in developing a patient-reported outcome (PRO) measure tailored to this population. Individuals with retinitis pigmentosa (RP) were recruited from the Kellogg Eye Center and the Association for the Blind and Visually Impaired. The study sample included 17 participants (53% female, mean age 48); median presenting visual acuity and Pelli-Robson contrast sensitivity were 20/40 and 1.2 log contrast sensitivity, respectively. The maximum horizontal extent of the Goldmann visual field was 11° in the better-seeing eye. Study participants completed a semi-structured qualitative interview, and two quality of life questionnaires. Interviews were recorded, transcribed and coded by two independent coders. Thematic analysis of the interview codes identified six vision-related quality of life themes across all RP participants: activity limitations, driving, emotional well-being, reading, mobility and social function. These themes will serve in the development of a PRO specific to severe PFL, which will facilitate evaluation and eventual evolution of low vision rehabilitation for patients with severe PFL
Trends in silicosis prevalence and the healthy worker effect among gold miners in South Africa: a prevalence study with follow up of employment status.
BACKGROUND: Given the intimate association between silicosis and tuberculosis, understanding the epidemiology of the South African gold mining industry silicosis epidemic is essential to current initiatives to control both silicosis and tuberculosis in this population, one of the most heavily affected globally. The study's objectives were to compare the prevalence of silicosis among working black gold miners in South Africa during 2004-2009 to that of previous studies, including autopsy series, and to analyse the influence of silicosis and/or tuberculosis on exiting employment. METHODS: Routine chest radiographs from a cohort of gold miners were read for silicosis by an experienced reader (I), and a subset re-read by a B-trained reader (II). Two methods of presenting the readings were used. Additionally, with baseline status of silicosis and previous or active tuberculosis as predictors, survival analysis examined the probability of exiting the workforce for any reason during 2006-2011. RESULTS: Reader I read 11 557 chest radiographs and reader II re-read 841. Overall, silicosis prevalence (ILO ≥ 1/0: 5.7 and 6.2% depending on reader method) was similar to the age adjusted prevalence found in a large study in 1984 (5.0%). When comparison was restricted to a single mine shaft previously studied in 2000, a decline in prevalence (ILO ≥ 1/1) was suggested for one of the reading methods (duration adjusted 20.5% vs. 13.0% in the current study). These findings are discordant with a long-term rising autopsy prevalence of silicosis over this period. Overall, relative to miners with neither disease, the adjusted hazard ratio for exiting employment during the follow-up period was 1.54 for baseline silicosis [95% confidence interval (CI) 1.17, 2.04], 1.71 for tuberculosis (95% CI 1.51, 1.94) and 1.53 for combined disease (95% CI 1.20, 1.96). CONCLUSIONS: This study found, a) there was no significant decline in overall silicosis prevalence among working black miners in the South African gold mining industry between 1984 and 2004-2009, and b) a possible decline at one mine shaft more recently. In the absence of evidence of declining respirable silica concentrations between the 1980s and 2000s, the trends found are plausibly due to a healthy worker survivor effect, which may be accelerating
Predictors of silicosis and variation in prevalence across mines among employed gold miners in South Africa
Background
The stated intention to eliminate silicosis from the South African goldmining industry as well as current programmes to find and compensate ex-miners with silicosis require an understanding of variation in silicosis prevalence across the industry. We aimed to identify the predictors of radiological silicosis in a large sample of working miners across gold mines in South Africa.
Methods
Routine surveillance chest radiographs were collected from 15 goldmine “clusters” in a baseline survey undertaken in preparation for a separate tuberculosis isoniazid prophylaxis trial. All images were read for silicosis by a health professional experienced in using the International Labour Organisation (ILO) classification. Profusion thresholds of > 1/0 and > 1/1 were used. Demographic and occupational information was obtained by questionnaire. Predictors of silicosis were examined in a multivariable logistic regression model, including age, gender, racial ascription, country of origin, years since starting mine employment, mine shaft, skill category, underground work status and tuberculosis.
Results
The crude silicosis prevalence at ILO > 1/1 was 3.8% [95% confidence interval (CI) 3.5–4.1%]. The range across mine shafts was 0.8–6.9%. After adjustment for covariates, the interquartile range across shafts was reduced from 2.4 to 1.2%. Black miners [adjusted odds ratio (aOR) 2.8; 95% CI 1.1–7.2] and miners in full-time underground work (aOR 2.1; 95% CI 1.3–3.4) had substantially elevated odds of silicosis, while workers from Mozambique had lower odds (aOR 0.54; 95% CI 0.38–0.77). Silicosis odds rose sharply with both age and years since starting in the industry (p for linear trend 15 years since first exposure and 2.2% < 10 years.
Conclusions
In surveillance of silicosis in working gold miners time since first exposure remains a powerful predictor. Age appears to be an independent predictor, while the detection of radiological silicosis in short-service miners requires attention. Public risk reporting by mines should include factors bearing on silicosis prevalence, specifically dust concentrations, with independent verification. Studies of silicosis and tuberculosis in ex-miners are needed, supported by an accessible electronic database of the relevant medical and dust exposure records of all gold miners
Quality of Relationships with Parents and Friends in Adolescence Predicts Metabolic Risk in Young Adulthood
Objective:
This study was designed to examine whether family and peer relationships in adolescence predict the emergence of metabolic risk factors in young adulthood. Method:
Participants from a large, nationally representative cohort study (N = 11,617 for these analyses) reported on their relationship experiences with parents and close friends during adolescence. Fourteen years later, interviewers collected blood samples, as well as anthropometric and blood pressure measurements. Blood samples were analyzed for HbA1c.
Results:
Ordered logistic regressions revealed that for females, supportive parent–child relationships and close male friendships in adolescence were associated with reduced odds of having elevated metabolic risk markers in young adulthood. These effects remained significant even after controlling for baseline measures of body mass index (BMI) and health and demographic covariates. The protective effects of close relationships were not significant for males, however. Exploratory analyses with 2-parent families revealed that supportive father–child relationships were especially protective for females.
Conclusions:
These findings suggest that, for females, close and supportive relationships with parents and male friends in adolescence may reduce the risk of metabolic dysregulation in adulthood

Adolescent attachment and informant depressive symptoms were examined as 2 explanations for absolute and directional discrepancies about adolescent symptoms, relationships, and social behavior in a sample of 189 eleventh-grade students (mean age = 16.5 years). Adolescent attachment predicted absolute discrepancies, with greater attachment coherence associated with fewer discrepancies in reports of adolescent depressive symptoms, parent–adolescent conflict, and adolescent externalizing behavior. Parents’ but not adolescents’ depressive symptoms sometimes predicted absolute discrepancies. Mothers’ depressive symptoms and adolescent attachment predicted the direction of discrepancies for mother–peer reports only.https://doi.org/10.1111/j.1467-8624.2010.01530.
Tipping Points in Adolescent Adjustment: Predicting Social Functioning from Adolescents’ Conflict with Parents and Friends
©American Psychological Association, 2012. This paper is not the copy of record and may not exactly replicate the authoritative document published in the APA journal. The final article is available, upon publication, at: https://doi.org/10.1037/a0029868Despite widespread interest in examining the role of conflict for adolescent development, researchers only rarely have examined adolescents' experiences of conflict across relationships. The present study examined how adolescents' experiences of conflict with parents and friends were linked to their social functioning. Adolescents (n = 189) and their mothers and fathers participated in semistructured discussions about areas of parent-adolescent conflict in the laboratory. In addition, adolescents reported about conflict in their best friendships, and peers reported about adolescents' social acceptance and behavior in social settings. Parent–adolescent conflict was associated with peer-reported aggression and delinquency, and friendship conflict was associated with delinquency and prosocial behavior. In addition, significant Parent–Adolescent Conflict × Friend–Adolescent Conflict interactions revealed that parent–adolescent conflict was associated with poor social functioning only when conflict with best friends was also high. The findings suggest that consideration of conflict across relationships may yield insight into the specific contexts in which conflict is associated with negative outcomes for adolescents.
