Anchoring effect in legal decision-making: A meta-analysis.

The prevalence of gaming disorder is assumed to be between 2%−5%. The treatment effect of different therapeutic interventions of gaming disorder has not been studied extensively. This systematic review and meta-analysis sought to identify all intervention studies on gaming disorder with a control group, determine the effect of the interventions, and examine moderators. Studies applying a therapeutic intervention and using an appropriate comparison group were identified by searching electronic databases, previous reviews, and reference lists. Data on type of treatment, name of outcome measurement, symptom level and other study characteristics were extracted and analyzed using meta-analysis and meta-regression. A total of 38 studies and 76 effect sizes, originating from 9524 participants were included. RoB2 and ROBINS-I risk of bias tools were used to assess within-study risk of bias. Correlational hierarchical models with robust variance estimation were fitted to effect size data and yielded a moderate summary estimate. Egger’s sandwich test, funnel plot inspections, and other tests were conducted to assess risk of bias between studies. Results indicate that there may be an overall effect of therapeutic interventions for gaming disorder, but confidence in these findings is compromised by small-study effects, possible publication bias, a limited study pool, and a lack of standardization. The field needs more higher quality studies before the evidence-base can support reliable meta-analytic estimates.

BackgroundRemote ischemic preconditioning (RIPC) is a promising approach to preventing acute kidney injury (AKI), but its efficacy is controversial.MethodsA systematic review of 30 randomized controlled trials was conducted to investigate the effects of RIPC on the incidence and outcomes of AKI. Random effects model meta-analyses and meta-regressions were used to generate summary estimates and explore sources of heterogeneity. The primary outcome was incidence of AKI and hospital mortality.ResultsThe total pooled incidence of AKI in the RIPC group was 11.5 %, significantly less than the 23.3 % incidence in the control group (P = 0.009). Subgroup analyses indicated that RIPC significantly reduced the incidence of AKI in the contrast-induced AKI (CI-AKI) subgroup from 13.5 % to 6.5 % (P = 0.000), but not in the ischemia/reperfusion-induced AKI (IR-AKI) subgroup (from 29.5 % to 24.7 %, P = 0.173). Random effects meta-regression indicated that RIPC tended to strengthen its renoprotective effect (q = 3.95, df = 1, P = 0.047) in these trials with a higher percentage of diabetes mellitus. RIPC had no significant effect on the incidence of stages 1–3 AKI or renal replacement therapy, change in serum creatinine and estimated glomerular filtration rate (eGFR), hospital or 30-day mortality, or length of hospital stay. But RIPC significantly increased the minimum eGFR in the IR-AKI subgroup (P = 0.006) compared with the control group. In addition, the length of ICU stay in the RIPC group was significantly shorter than in the control group (2.6 vs 2.0 days, P = 0.003).ConclusionsWe found strong evidence to support the application of RIPC to prevent CI-AKI, but not IR-AKI.Electronic supplementary materialThe online version of this article (doi:10.1186/s13054-016-1272-y) contains supplementary material, which is available to authorized users.

Primary studies increasingly report information that can be used to provide multiple effect sizes. Of interest in this study, primary studies might compare a treatment and a control group on multiple related outcomes that result in multiple dependent effect sizes to be synthesized. There are a number of ways to handle the resulting within-study "multiple-outcome" dependency. The present study focuses on use of the multilevel meta-analysis model (Van den Noortgate, López-López, Marín-Martínez, & Sánchez-Meca, 2013) and robust variance estimation (Hedges, Tipton, & Johnson, 2010) for handling this dependency, as well as for estimating outcome-specific mean effect sizes. We assessed these two approaches under various conditions that differed from each other in within-study sample size; the number of effect sizes per outcome; the number of outcomes per study; the number of studies per meta-analysis; the ratio of variances at Levels 1, 2, and 3; and the true correlation between pairs of effect sizes at the between-study level. Limitations and directions for future research are discussed.

Postanesthesia Care Unit Visitation, Anxiety, and Experimental Design

Physical cleansing is a human universal. It serves health and survival functions. It also carries rich psychological meanings that interest scholars across disciplines. What psychological effects result from cleansing? What psychological states trigger cleansing? The present meta-analysis takes stock of all experimental studies examining the psychological consequences and antecedents of cleansing-related thoughts, feelings, and behaviors (e.g., feeling less guilty after cleansing; spontaneously cleansing oneself after thinking of unwelcomed sexual encounter). It includes 129 records, 230 experiments, and 551 effects from 42,793 participants. Effect sizes were synthesized in random-effects models using robust variance estimates with small-sample corrections, supplemented by other techniques. Outliers were excluded using leave-one-out diagnostics and sensitivity analysis. Publication bias was assessed and corrected for using eight methods. Theoretical, methodological, sample, and report moderators were coded. After excluding outliers, without bias correction, the synthesized effect size estimate was g = 0.315, 95% CI [0.277, 0.354]. Using various bias correction methods, the estimate ranged from g = 0.103 to 0.331 and always exhibited considerable heterogeneity. Effect sizes were especially large for behavioral measures and varied significantly between sample types, sample regions, and report types. Meanwhile, effects were domain-general (observed in the moral domain and beyond), bidirectional (physical cleansing ↔ psychological variables), and robust across theoretical types, manipulation operationalizations, and study designs. Limitations included mixed replicability, suboptimal methodological rigor, and restricted sample diversity. We recommend future studies to (a) incorporate power analysis, preregistration, and replication; (b) investigate generalizability across samples; (c) strengthen discriminant validity; and (d) test competing theoretical accounts.

We conducted a meta-analysis of randomized controlled trials designed to promote smoking cessation among cancer survivors to (a) assess how effective interventions are at increasing quit rates, and (b) determine which intervention strategies are associated with effect sizes. Out of 10,848 records that were located using computerized searches and informal sources, 21 interventions met the inclusion criteria for the review. We developed a bespoke taxonomy of 36 categories of techniques designed to change smoking behavior, and coded sample, intervention, and methodological characteristics. Random effects meta-analysis and metaregressions were conducted. The sample-weighted average effect size for smoking cessation was d+ = .030, and was not significantly different from zero (95%CI = -.042 to .101). Effect sizes exhibited both publication bias and small sample bias. Metaregressions indicated that, out of the many potential moderators that were tested, just a single intervention feature was associated with effect sizes. Interventions delivered solely by nurses exhibited larger effects compared to interventions from other sources. The present review indicates that current smoking cessation interventions for cancer survivors are ineffective. High-quality and effective interventions are needed. We offer suggestions regarding promising intervention strategies. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Visual Analogue Scale has higher assay sensitivity than WOMAC pain in detecting between-group differences in treatment effects: a meta-epidemiological study

Legal experts can reliably ascertain which legal norms are valid, and therefore which legal propositions are true. Legal experts are in this position because they have a grasp of the deep cognitive structure of law: the habits, commitments, and values that characterize the practice of legal argument in a specific jurisdiction. Legal expertise, thus understood, determines the content of the law, which is therefore not reducible to an aggregation of authoritative legal texts. Because social facts about legal experts’ values and commitments can determine the content of the law, references to moral considerations and principles of justice as valid legal reasons, in legal argument, are not a problem for (at least some forms of) legal positivism. Legal expertise thus shows that non-positivists might be right about (as they would put it) the irreducibility of legal content to communicative content without being right about the claims that moral facts determine the content of the law or that the validity of legal norms turns on moral considerations. Legal expertise also plays an important causal role in legal decision-making and is not, as some of the literature on judicial decision-making might suggest, epiphenomenal. From a moral perspective, while the existence of a class of legal experts is not necessarily valuable, it does have certain benefits, particularly in conditions of moral disagreement.

To our knowledge, no previous meta-analysis has attempted to compare the efficacy of pharmacological, psychological and combined treatments for the three main anxiety disorders (panic disorder, generalized anxiety disorder and social phobia). Pre-post and treated versus control effect sizes (ES) were calculated for all evaluable randomized-controlled studies (n = 234), involving 37,333 patients. Medications were associated with a significantly higher average pre-post ES [Cohen's d = 2.02 (1.90-2.15); 28,051 patients] than psychotherapies [1.22 (1.14-1.30); 6992 patients; P < 0.0001]. ES were 2.25 for serotonin-noradrenaline reuptake inhibitors (n = 23 study arms), 2.15 for benzodiazepines (n = 42), 2.09 for selective serotonin reuptake inhibitors (n = 62) and 1.83 for tricyclic antidepressants (n = 15). ES for psychotherapies were mindfulness therapies, 1.56 (n = 4); relaxation, 1.36 (n = 17); individual cognitive behavioural/exposure therapy (CBT), 1.30 (n = 93); group CBT, 1.22 (n = 18); psychodynamic therapy 1.17 (n = 5); therapies without face-to-face contact (e.g. Internet therapies), 1.11 (n = 34); eye movement desensitization reprocessing, 1.03 (n = 3); and interpersonal therapy 0.78 (n = 4). The ES was 2.12 (n = 16) for CBT/drug combinations. Exercise had an ES of 1.23 (n = 3). For control groups, ES were 1.29 for placebo pills (n = 111), 0.83 for psychological placebos (n = 16) and 0.20 for waitlists (n = 50). In direct comparisons with control groups, all investigated drugs, except for citalopram, opipramol and moclobemide, were significantly more effective than placebo. Individual CBT was more effective than waiting list, psychological placebo and pill placebo. When looking at the average pre-post ES, medications were more effective than psychotherapies. Pre-post ES for psychotherapies did not differ from pill placebos; this finding cannot be explained by heterogeneity, publication bias or allegiance effects. However, the decision on whether to choose psychotherapy, medications or a combination of the two should be left to the patient as drugs may have side effects, interactions and contraindications.

PurposeThis study aims to use institutional and upper echelons theories to comprehensively investigate the intricate interplay between TMT legal expertise and firms' adaptive strategies in legal contexts, notably within emerging economies. It explores how upper echelons experiences shape opportunistic compliance strategies, impacting value and risk perceptions. Drawing on upper echelons theory, the research probes how TMT legal expertise molds firms’ involvement in significant lawsuits, accounting for influential roles. It scrutinizes TMT’s impact on legal strategies, positing that managerial discretion emerges from environmental factors, organizational attributes and executive traits. The study underscores TMT’s internal incentives and external factors’ interplay, molding strategic legal engagement.Design/methodology/approachTo validate this framework, statistical analysis is performed on data from 2,584 Chinese-listed firms. The data set spans 2010–2015, with 5,713 material lawsuits. Chosen due to reliable institutional-level incentives data from the China Market Index Database, years 2016–2019 are excluded for methodological disparities. Moreover, 2007–2009 is omitted to mitigate the potential financial crisis impact. This study’s 11,272 observations ensure robust empirical exploration, offering insights into the interplay of TMT legal expertise, institutional factors and firms’ legal strategies.FindingsThe study reveals that firms led by executives with legal expertise are more prone to engage in significant lawsuits, indicating strategic use of legal skills. TMT age moderates this, with older teams less likely to engage. TMT tenure’s effect remains unclear due to tenure-risk preference complexity. Institutional factors matter; less legally mature regions reduce managers’ legal risk intention. Results confirm hypotheses and highlight executive human capital’s impact on firms’ legal strategies.Research limitations/implicationsThis study acknowledges contributions while highlighting limitations, including the need for detailed distinctions in lawsuit roles and exploration of heterogeneous TMT power dynamics. Further research is proposed for nuanced power dynamics and comprehensive TMT legal background data. The study advances upper echelons theory by introducing TMT legal expertise as a factor influencing strategic lawsuit behavior. It challenges institutional theory by showing the adaptable legal context, beyond fixed constraints. Moderating factors – group risk attitude and external knowledge – deepen understanding of upper echelons’ impact. Enhanced data collection is encouraged to address limitations and refine findings.Practical implicationsThis study’s implications extend to managerial practices. Firms should acknowledge the dynamic legal system, using TMT legal expertise for strategic legal challenges. Executives should pragmatically approach regulations. While legal professionals enhance compliance, caution is needed in selecting TMT members with legal expertise due to the risk of misusing it for unnecessary litigation, potentially misaligned with financial performance goals.Originality/valueThis study combines institutional and upper echelons theories to explore TMT legal expertise’s impact on firms’ adaptive strategies in emerging economies. It challenges the idea of a universally constraining legal environment and highlights how TMT legal expertise enhances firms’ management of complex legal risks. The research introduces TMT legal expertise as an influencing factor in strategic lawsuits, revealing nuanced relationships between legal contexts and strategic decisions. The findings enrich upper echelons theory, challenge conventional institutional views and identify moderating factors that deepen the understanding of upper echelons’ influence in legal landscapes.

BackgroundDementia is assumed to alter mental capacity, which may necessitate legal guardianship. However, only limited research exists on how dementia affects mental capacity, and most studies have focused solely on a medical perspective and concentrate on memory functions. The aim of this qualitative study was to investigate physicians' and legal experts' perceptions on a broad range of cognitive and neuropsychiatric domains potentially affecting mental capacity and the need for guardianship in people with dementia.MethodsPhysicians (N = 30) and legal experts (N = 20) participated in semi‐structured individual interviews. The data were analyzed by using content analysis and further semi‐quantified according to the cognitive and neuropsychiatric domains.ResultsPhysicians considered neuropsychiatric symptoms and executive dysfunction to be the most important deficits in the legal context, while legal experts highlighted episodic memory impairment and dyscalculia. Perceptions regarding the importance of several cognitive and neuropsychiatric symptoms varied between and within the professional groups.ConclusionsPhysicians and legal experts diverged in their perceptions of cognitive and neuropsychiatric domains affecting mental capacity and the need for guardianship. The evaluation and influence of medical evidence among legal experts heavily rely on subjective opinions. Given the substantial potential impact on patients' equal access to their rights, developing standardized guidelines is essential.

The last three decades have witnessed significant advances in psychotherapy. Numerous scholarly articles and books have been devoted to pertinent topics in the field, making it difficult for the practicing clinician to keep up with this rapidly growing area. The purpose of this article is to provide some guidelines on how to evaluate the empirical literature in psychotherapy and then to explore three key areas: evidence-based psychotherapies for patients with psychiatric disorders, individual variables that predict differential outcome to treatment, and the therapeutic alliance. Finally, two case examples will be presented to illustrate how knowledge of the empirical literature can facilitate an evidence-based approach to the daily practice of psychotherapy in general psychiatry.

Objective: The aim of the study was to conduct a meta-analysis of research examining the early speech and language functioning of young children, birth to age 8;11 (years;months), with nonsyndromic cleft lip and/or palate (NSCL/P) compared to their peers without NSCL/P.Method: We conducted a random-effects metaregression using 241 effect sizes from 31 studies comparing 955 young children with NSCL/P to 938 typically developing peers on measures of speech and language functioning. Moderators were sample characteristics (i.e., age, cleft type, publication year, and study location) and measurement characteristics (i.e., speech sample material, language modality and domain, and assessment type).Results: Young children with NSCL/P scored significantly lower on measures of speech and language compared to children without NSCL/P. Children with NSCL/P had smaller consonant inventories (standardized mean difference effect size [ESg] = −1.24), less accurate articulation (ESg = −1.13), and more speech errors (ESg = 0.93) than their peers. Additionally, children with NSCL/P had poorer expressive (ESg = −0.57) and receptive (ESg = −0.59) language skills than their peers. Age and assessment type moderated effect sizes for expressive language. As children with NSCL/P aged, their expressive language performance became more similar to their peers. Expressive language effect sizes from parent reports and observational language measures (estimated effect size = −0.74) were significantly lower than those from standardized norm-referenced tests (estimated effect size = −0.45).Conclusions: These findings suggest that young children with NSCL/P experience delays relative to their peers across multiple speech and language constructs. Differences between children with NSCL/P and their typically developing peers appear to decrease with age.Supplemental Material S1. PRISMA 2009 Checklist.Supplemental Material S2.

What does the facial dot-probe task tell us about attentional processes in social anxiety? A systematic review

The objective of the study was to review current literature to determine whether the topical application of platelet-rich plasma (PRP) promotes healing in experimentally-induced full-thickness skin wounds in animals. The hypothesis was that the adjunct of PRP has a positive effect on wound healing. An electronic search was carried out on the following databases: Web of Science, Cochrane Library, PubMed, Research Gate, Cochrane Wounds Group, Veterinary Information Network. No publication date nor language restrictions were applied. Randomised and not randomised controlled clinical trials comparing PRP with placebo or with other treatments were included. The reduction of open wound area in PRP-treated (test) wounds compared to control wounds was the primary outcome. Secondary outcomes were healing time and number of healed cases in test group compared to control. The following effect sizes were calculated: the Hedges’ g for continuous variables; the odds ratio for binary data. Eighteen controlled clinical trials were included in the qualitative and quantitative synthesis, with a total of 661 wounds. All studies were published in the period 2007–2016. Eight studies were carried out on rodent/lagomorph mammals and 10 on non-rodent/lagomorph mammals. In all included studies, control wounds underwent placebo or were left untreated. The PRP group showed a better healing performance than the control group in each outcome. The effect size was statistically significant considering the primary outcome and the overall aggregation of the three outcomes. The effect size, although in favour of the treatment with PRP, was not significant considering the healing time and the number of healings. The overall heterogeneity was mild or moderate. Five studies reported a high risk of selection bias. The publication bias was always mild or absent. The results support the hypothesis of the positive effects of the PRP when compared to control groups in the treatment of experimentally-induced full-thickness skin wounds in animals. PRP can therefore be considered an effective adjunctive therapy in stimulating second intention healing of acute wounds in healthy animals.
