Psychological bulletin 20090701 4
Perceived discrimination has been studied with regard to its impact on several types of health effects. This meta-analysis provides a comprehensive account of the relationships between multiple forms of perceived discrimination and both mental and physical health outcomes. In addition, this meta-analysis examines potential mechanisms by which perceiving discrimination may affect health, including through psychological and physiological stress responses and health behaviors. Analysis of 134 sampl ...[more]

Project description:This meta-analytic study systematically investigates the relations between perceived racial/ethnic discrimination and socioemotional distress, academics, and risky health behaviors during adolescence, and potential variation in these relations. The study included 214 peer-reviewed articles, theses, and dissertations, with 489 unique effect sizes on 91,338 unique adolescents. Random-effects meta-analyses across 11 separate indicators of well-being identified significant detrimental effects. Greater perceptions of racial/ethnic discrimination were linked to more depressive and internalizing symptoms; greater psychological distress; poorer self-esteem; lower academic achievement and engagement; less academic motivation; greater engagement in externalizing behaviors, risky sexual behaviors, and substance use; and more associations with deviant peers. Metaregression and subgroup analyses indicated differences by race/ethnicity, Gender × Race/Ethnicity interactions, developmental stage, timing of retrospective measurement of discrimination, and country. Overall, this study highlights the pernicious effects of racial/ethnic discrimination for adolescents across developmental domains and suggests who is potentially at greater risk.

Project description:BACKGROUND:As mobile technology continues expanding, researchers have been using mobile phones to conduct health interventions (mobile health-mHealth-interventions). The multiple features of mobile phones offer great opportunities to disseminate large-scale, cost-efficient, and tailored messages to participants. However, the interventions to date have shown mixed results, with a large variance of effect sizes (Cohen d=-0.62 to 1.65). OBJECTIVE:The study aimed to generate cumulative knowledge that informs mHealth intervention research. The aims were twofold: (1) to calculate an overall effect magnitude for mHealth interventions compared with alternative interventions or conditions, and (2) to analyze potential moderators of mHealth interventions' comparative efficacy. METHODS:Comprehensive searches of the Communication & Mass Media Complete, PsycINFO, Web of Knowledge, Academic Search Premier, PubMed and MEDLINE databases were conducted to identify potentially eligible studies in peer-reviewed journals, conference proceedings, and dissertations and theses. Search queries were formulated using a combination of search terms: "intervention" (Title or Abstract) AND "health" (Title or Abstract) AND "*phone*" OR "black-berr*" (OR mHealth OR "application*" OR app* OR mobile OR cellular OR "short messag*" OR palm* OR iPhone* OR MP3* OR MP4* OR iPod*) (Title or Abstract). Cohen d was computed as the basic unit of analysis, and the variance-weighted analysis was implemented to compute the overall effect size under a random-effects model. Analysis of variance-like and meta-regression models were conducted to analyze categorical and continuous moderators, respectively. RESULTS:The search resulted in 3424 potential studies, the abstracts (and full text, as necessary) of which were reviewed for relevance. Studies were screened in multiple stages using explicit inclusion and exclusion criteria, and citations were evaluated for inclusion of qualified studies. A total of 64 studies were included in the current meta-analysis. Results showed that mHealth interventions are relatively more effective than comparison interventions or conditions, with a small but significant overall weighted effect size (Cohen d=0.31). In addition, the effects of interventions are moderated by theoretical paradigm, 3 engagement types (ie, changing personal environment, reinforcement tracking, social presentation), mobile use type, intervention channel, and length of follow-up. CONCLUSIONS:To the best of our knowledge, this is the most comprehensive meta-analysis to date that examined the overall effectiveness of mHealth interventions across health topics and is the first study that statistically tested moderators. Our findings not only shed light on intervention design using mobile phones, but also provide new directions for research in health communication and promotion using new media. Future research scholarship is needed to examine the effectiveness of mHealth interventions across various health issues, especially those that have not yet been investigated (eg, substance use, sexual health), engaging participants using social features on mobile phones, and designing tailored mHealth interventions for diverse subpopulations to maximize effects.

Project description:Identity concealment affects all sexual minority individuals, with potentially complex mental health implications. Concealing a sexual minority identity can simultaneously generate the stress of hiding, protect against the stress of discrimination, and keep one apart from sexual minority communities and their norms and supports. Not surprisingly, existing studies of the association between sexual orientation concealment and mental health problems show contradictory associations-from positive to negative to null. This meta-analysis attempts to resolve these contradictions. Across 193 studies (n = 92,236) we find a small positive association between sexual orientation concealment and internalizing mental health problems (i.e., depression, anxiety, distress, problematic eating; ESr = 0.126; 95% CI [0.102, 0.151]) and a small negative association between concealment and substance use problems (ESr = -0.061; 95% CI [-0.096, -0.026]). The association between concealment and internalizing mental health problems was larger for those studies that assessed concealment as lack of open behavior, those conducted recently, and those with younger samples; it was smaller in exclusively bisexual samples. Year of data collection, study location, and sample gender, education, and racial/ethnic composition did not explain between-study heterogeneity. Results extend existing theories of stigma and sexual minority mental health, suggesting potentially distinct stress processes for internalizing problems versus substance use problems, life course fluctuations in the experience of concealment, distinct experiences of concealment for bisexual individuals, and measurement recommendations for future studies. Small overall effects, heavy reliance on cross-sectional designs, relatively few effects for substance use problems, and the necessarily coarse classification of effect moderators in this meta-analysis suggest future needed methodological advances to further understand the mental health of this still-increasingly visible population.

Project description:BACKGROUND:Public health guidelines suggest that physical activity can be accumulated in multiple short bouts dispersed through the day. A synthesis of the evidence for this approach is lacking. OBJECTIVE:Our objective was to undertake a systematic review and meta-analysis to examine if exercise interventions consisting of a single bout of exercise compared with interventions comprising the same total duration, mode, and intensity of exercise accumulated over the course of the day have different effects on health outcomes in adults. METHODS:Six electronic databases were searched (Jan 1970-29 August 2018). Two authors identified studies that evaluated the effects of a single bout of exercise compared with the same intensity, total duration, and mode of exercise accumulated in multiple bouts over the course of a day, in community-dwelling adults. Risk of bias was assessed using the Cochrane Collaboration tool. Pooled effects were reported as standardised mean differences (MDs) and 95% confidence intervals (CIs) using a random effects model. RESULTS:A total of 19 studies involving 1080 participants met the inclusion criteria. There were no differences between accumulated and continuous groups for any cardiorespiratory fitness or blood pressure outcomes. A difference was found in body mass changes from baseline to post-intervention in favour of accumulated exercise compared with continuous (MD -?0.92 kg, 95% CI -?1.59 to -?0.25, I2?=?0%; five studies, 211 participants). In subgroup analyses, accumulating >?150 min of weekly exercise in multiple bouts per day resulted in small effects on body fat percentage (combined post-intervention and change from baseline values: MD -?0.87%, 95% CI -?1.71 to -?0.04, I2?=?0%; three studies, 166 participants) compared with 150 min of exercise amassed via single continuous bouts per day. There was a decrease in low-density lipoprotein (LDL) cholesterol with accumulated versus continuous exercise (MD -?0.39 mmol/l, 95% CI -?0.73 to -?0.06, I2?=?23%; two studies, 41 participants). No differences were observed for any other blood biomarker (total cholesterol, high-density lipoprotein cholesterol, triglycerides, fasting blood glucose, and fasting insulin). CONCLUSIONS:There is no difference between continuous and accumulated patterns of exercise in terms of effects on fitness, blood pressure, lipids, insulin and glucose. There is some evidence from a small number of studies that changes in body mass and LDL cholesterol are more favourable following the accumulated condition. Collectively our findings suggest that adults are likely to accrue similar health benefits from exercising in a single bout or accumulating activity from shorter bouts throughout the day. This review will inform public health guidelines for physical activity at the global and national levels (PROSPERO 2016 CRD42016044122).

Project description:Discrimination in healthcare is associated with fetal growth restriction, preterm birth, and postpartum depression. A community-based participatory research study was designed to measure perceived discrimination and healthcare quality during prenatal care and delivery by a community health center, where the majority of patients served belong to historically marginalized ethnic and racial groups. A 34-question phone survey was administered to women 18 years and older who received prenatal care at the study site during 2020-2021. The primary outcome was perceived discrimination during obstetric care, measured by the 7-question Discrimination in the Medical Setting (DMS) survey. Secondary outcomes included the association of race with perceived discrimination, quality of care, trust of healthcare providers, and perceived control over medical choices. Ninety-seven women completed the survey, 95 of whom were women of color. The sample was dichotomized into Black (n = 49) and non-Black (n = 46). Perceived discrimination for all participants was 21% (20/95), with 31% (15/49) of Black women reporting any discrimination during prenatal care and delivery. Compared to other women of color, Black women reported higher rates of perceived discrimination (31% vs 11%, aOR 3.9 [1.2-12.1], p < 0.05), lower control over health choices (84% vs 98%, aOR 0.1 [0.0-0.8], p < 0.05), and were more likely to perceive lack of respect (12% vs 2%, p = 0.045). Although perceived discrimination at this community health center was low compared to prior studies, Black women experienced higher rates of discrimination than other women of color.

Project description:The increasing prevalence of problematic internet use has heightened concerns about its adverse impact on internet users' mental health. Despite reviews investigating the associations between problematic internet use and mental health outcomes, there is a lack of understanding of various aspects of students' mental health. This study aimed to bridge this gap by providing a more comprehensive overall picture of this issue through a quantitative synthesis based on three-level random-effects meta-analytic models. In total, 223 studies with a cumulative total of 498,167 participants and 512 effect sizes were included in this synthesis. The results showed that problematic internet use was moderately and positively associated with depressive symptoms, anxiety, loneliness, and other mental health outcomes, and negatively related to subjective well-being. Moderator analyses revealed that several study features (i.e., school grade, region, measure of problematic internet use, publication year, and gender) could explain the variations in the findings across individual studies. These research results provide solid evidence for the link between problematic internet use and different mental health outcomes and have implications for future research and interventions on students' problematic internet use.Supplementary informationThe online version contains supplementary material available at 10.1007/s40894-022-00201-9.

Project description:Religion and spirituality (R/S) play an important role in the daily lives of many cancer patients. There has been great interest in determining whether R/S factors are related to clinically relevant health outcomes. In this meta-analytic review, the authors examined associations between dimensions of R/S and social health (eg, social roles and relationships). A systematic search of the PubMed, PsycINFO, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature databases was conducted, and data were extracted by 4 pairs of investigators. Bivariate associations between specific R/S dimensions and social health outcomes were examined in a meta-analysis using a generalized estimating equation approach. In total, 78 independent samples encompassing 14,277 patients were included in the meta-analysis. Social health was significantly associated with overall R/S (Fisher z effect size = .20; P < .001) and with each of the R/S dimensions (affective R/S effect size = 0.31 [P < .001]; cognitive R/S effect size = .10 [P < .01]; behavioral R/S effect size = .08 [P < .05]; and 'other' R/S effect size = .13 [P < .001]). Within these dimensions, specific variables tied to social health included spiritual well being, spiritual struggle, images of God, R/S beliefs, and composite R/S measures (all P values < .05). None of the demographic or clinical moderating variables examined were significant. Results suggest that several R/S dimensions are modestly associated with patients' capacity to maintain satisfying social roles and relationships in the context of cancer. Further research is needed to examine the temporal nature of these associations and the mechanisms that underlie them.

Project description:Neophobia, the fear of novel stimuli, plays a major role in animal ecology. Here, we review studies on predator neophobia and explore its underlying patterns within an ecological framework. Predator neophobia is typically assessed by observing behaviours in novel areas that bring potential risk from unknown predators, or by observing behaviours towards certain kinds of objects and odours that are novel. We conducted a literature review across taxa, surveying research on baseline and induced neophobia versus controls. We calculated effect sizes for the intensity of neophobic responses, and categorized data according to six factors (taxa, age class, background type, trophic position, test cue type and experimental treatment type). While accounting for each of the other factors, we found that baseline neophobia was stronger among birds and mammals, and towards novel areas, relative to other taxa and cue types. Baseline neophobia was lower for wild-caught animals and for those that were higher in trophic position, compared with those reared in captivity and from lower trophic levels. By contrast, induced neophobia was similar in intensity across taxa, background types and testing cue types, while again being lower among upper trophic-level members and among juvenile animals. Although induced neophobia occurred across all treatment types, brain lesions induced stronger neophobia than predation risk or social isolation. We discuss potential mechanisms underlying these results and highlight gaps in the literature.

Project description:Workplace ostracism, which is regarded as "social death," is rampant in organizations and has attracted significant research attention. We extend the understanding of workplace ostracism by conducting a meta-analysis of studies of the relationships between workplace ostracism and its consequences. We also explore the moderating effects of national culture (i.e., collectivism vs. individualism) and the mediating effects of organization-based self-esteem (OBSE). The results of a meta-analysis of 95 independent samples (N = 26,767) reveal that exposure to workplace ostracism is significantly related to individuals' attitudes, well-beings, and behaviors. Moreover, the effects of workplace ostracism on belongingness, job satisfaction, emotional exhaustion, organizational citizenship behavior (OCB) toward individuals (OCBI), organizational deviance, and interpersonal deviance are stronger in individualist contexts than in collectivist contexts. However, the relationships between workplace ostracism and organizational identification and OCB are stronger in collectivist contexts than in individualist contexts. Our meta-analytical structural equation modeling also provides evidence of the mediating effects of OBSE on the relationships between workplace ostracism and organizational commitment, job satisfaction, and job performance. The implications and limitations of our study and future research directions are also discussed.

Project description:Through long-term training, music experts acquire complex and specialized sensorimotor skills, which are paralleled by continuous neuro-anatomical and -functional adaptations. The underlying neuroplasticity mechanisms have been extensively explored in decades of research in music, cognitive, and translational neuroscience. However, the absence of a comprehensive review and quantitative meta-analysis prevents the plethora of variegated findings to ultimately converge into a unified picture of the neuroanatomy of musical expertise. Here, we performed a comprehensive neuroimaging meta-analysis of publications investigating neuro-anatomical and -functional differences between musicians (M) and non-musicians (NM). Eighty-four studies were included in the qualitative synthesis. From these, 58 publications were included in coordinate-based meta-analyses using the anatomic/activation likelihood estimation (ALE) method. This comprehensive approach delivers a coherent cortico-subcortical network encompassing sensorimotor and limbic regions bilaterally. Particularly, M exhibited higher volume/activity in auditory, sensorimotor, interoceptive, and limbic brain areas and lower volume/activity in parietal areas as opposed to NM. Notably, we reveal topographical (dis-)similarities between the identified functional and anatomical networks and characterize their link to various cognitive functions by means of meta-analytic connectivity modelling. Overall, we effectively synthesized decades of research in the field and provide a consistent and controversies-free picture of the neuroanatomy of musical expertise.
