Background: This study systematically located and appraised peer-reviewed evidence for the efficacy of strategies to increase organ donation decision communication among adults including an assessment of study quality to guide future research in this field. There is little room to move in strengthening unanimously positive public attitudes toward organ donation. Consequently, researchers have called for a focus on organ donation decision communication to understand modifiable factors to increase organ donation rates. Methods: Multiple databases were searched during September 2015, and 44 studies were selected for inclusion. Data concerning participants, design, and outcomes were extracted. Studies were rated for quality and levels of evidence. Findings: Although not amenable to meta-analysis, the literature indicates that approximately 50% of adults who are willing to become an organ donor have discussed this decision with family. The majority of research was conducted in a Western context with an overrepresentation of students. Strategies to increase communication include education, motivation, input from lived experience, efforts to address salient audience beliefs, and scheduled reminders or prompts. Intentions and willingness to discuss organ donation were consistently positively related to discussion behavior; however, formative research and experimental studies testing theoretically driven interventions were scarce. Conclusions: There is mixed evidence for the role of demographic and attitudinal characteristics in the success of organ donation communication interventions. Additional theoretically based research is recommended to establish boundary conditions and validate strategies to increase organ donation decision communication among adults.

Although convergent research demonstrates that well-designed graphics can facilitate readers’ understanding of text, there are select situations where graphics have been shown to have no effect on learners’ overall text comprehension. Therefore, the current meta-analytic study examined 39 experimental studies published between 1985 and 2018 measuring graphics’ effects on readers’ comprehension. We first quantified the overall effect on reading comprehension. Then, we considered interactions with learners’ characteristics, graphic types, and assessment formats. Our analysis revealed that the inclusion of graphics had a moderate overall positive effect (Hedges’s g = 0.39) on students’ reading comprehension, regardless of grade level. Regarding graphic type, we did not find a significant difference among pictures, pictorial diagrams, and flow diagrams. Only when compared to mixed graphics, pictures had a greater effect on comprehension. Additionally, compared with true and false assessments, graphics differentially benefited students’ comprehension on open-ended comprehension assessments and mixed format assessments. Implications for future research are presented.

This meta-analysis examined the effectiveness of supplemental Tier-2 mathematics interventions for students with mathematics difficulties (MD). We reviewed 39 experimental and quasi-experimental studies that included 40 independent samples, with 61 treatment groups. Utilizing robust variance estimation (RVE), results revealed a treatment effect of 0.41. Mixed-effects meta-regression analyses revealed that Tier-2 interventions were moderated by intervention model type, group size, and type of measure. We present recommendations for future research and implementation of mathematics practices.

This review presents a synthesis and a critique of the development of the existing workfamily (WF) literature during the last decade in order to highlight gaps and limitations in current research. The study revises 83 peer-reviewed articles, book chapters and conference presentations (2004-2014) related to WF in economics, management and psychology disciplines, and classifies the current research into three broad themes for future research paths: i) definitions and theories; ii) background and outcomes of wf conflict, balance and enrichment; and iii) methodological gaps. Advances have been made this decade on meta-analysis and the understanding of the positive side of WF interface. Future research opportunities in this field will include a deeper understanding of how to effectively cope with WF conflict, how to achieve WF enrichment, the use of different methods (qualitative, longitudinal and experimental studies) on samples of new occupations, and how researchers could address methodological problems (causality, endogeneity, simultaneity, effect size, and self-selection bias) to better handle the complexity of WF issues.

Review Protocol

Tobacco use is the leading cause of preventable death in Ireland with almost 6,000 smokers dying each year from smoking-related diseases. Amongst younger Irish women, smoking rates are considerably higher in those from socially disadvantaged areas compared to women from affluent areas. Women from poorer areas also experience higher rates of lung cancer. To our knowledge, there are no peer reviewed published systematic reviews on the effectiveness of interventions tailored to reduce smoking rates in women from disadvantaged areas. This systematic review protocol will aim to examine the effectiveness of such interventions and to describe trial processes such as recruitment, follow-up and dropout prevention strategies, as well as barriers and enablers of successful implementation.    A systematic review will be conducted of peer-reviewed randomised controlled trials and associated process evaluations of smoking cessation interventions designed for women living in socially disadvantaged areas. If the search returns, less than five studies are review criteria will expand to include quasi-experimental studies. A number of databases of scholarly literature will be searched from inception using a detailed search strategy. Two independent reviewers will screen titles, abstracts and full-text articles to identify relevant studies using a pre-defined checklist based on PICOS. In the case of disagreement, a third reviewer will be consulted. The quality of included studies will be assessed using the ‘Grading of Recommendations Assessment, Development and Evaluation’ (GRADE) criteria. Quantitative data will be extracted and, if comparable, will be assessed using meta-analysis. A narrative meta-synthesis of qualitative data will be conducted.   This review aims to synthesise information from relevant studies on smoking cessation interventions tailored for women from socially disadvantaged areas. The evidence obtained from studies and presented in this review will help guide future research in this area. Registration: This review will be registered with International Prospective Register of Systematic Reviews (PROSPERO).

Self Compassion

Poor sleep quality is highly prevalent in modern societies and negatively linked to various health outcomes. While previous research has demonstrated preliminary evidence for self-compassion as a tool for improving sleep quality, this review provides a meta-analysis of respective published and unpublished results of our own research group using German samples. A total of nine studies are included (N = 956 participants), consisting of both correlational and experimental data. Across these studies, there was a medium correlation between self-compassion and subjective sleep quality, r = 0.303, 95% CI (0.244; 0.360). In three experimental studies, a small increase in participants’ self-reported sleep quality emerged, in comparison to control conditions, Hedges’ s g = 0.484, 95% CI (0.148; 0.821). Limitations on study level concern both the small sample sizes and short-term analyses of intervention effects. As a conclusion, this review supports both the correlational and causal relationship between self-compassion and increased subjective sleep quality across diverse operationalizations and samples. Future research should focus on the moderating effects of intervention type, duration of intervention effects, and type of target population.

abstractConceptual metaphor theory and other important theories in metaphor research are often experimentally tested by studying the effects of metaphorical frames on individuals’ reasoning. Metaphorical frames can be identified by at least two levels of analysis: words vs. concepts. Previous overviews of metaphorical-framing effects have mostly focused on metaphorical framing through words (metaphorical-words frames) rather than through concepts (metaphorical-concepts frames). This means that these overviews included only experimental studies that looked at variations in individual words instead of at the broader logic of messages. For this reason, we conducted a meta-analysis (k = 91, N = 34,783) to compare the persuasive impact of both types of metaphorical frames. Given that patterns of metaphor usage differ across discourse domains, and that effects may differ across modalities and discourse domains, we focused on one mode of presentation and one discourse domain only: verbal metaphorical framing in political discourse. Results showed that, compared to non-metaphorical frames, both metaphorical-words and metaphorical-concepts frames positively influenced beliefs and attitudes. Yet, these effects were larger for metaphorical-concepts frames. We therefore argue that future research should more explicitly describe and justify which level of analysis is chosen to examine the nature and effects of metaphorical framing.

Meta Analyses

This review and meta-analysis explores the experimental effects of expansive and contractive motor displays on affective, hormonal, and behavioral responses. Experimental studies were located through systematic literature searches. Studies had to manipulate motor displays to either expansive or contractive displays and investigate the effect of the displays on affect, hormones, or overt behavior. Meta-analyses were conducted to determine the pooled, standardized mean differences between the effects of motor displays on affective, hormonal, and behavioral responses. From 5,819 unique records, 73 relevant studies were identified. Robust differences between expansive and contractive displays emerged for affective responses and overt behavioral responses across contexts, type of manipulation, and methods of measurement. The results suggest that the effects are driven by the absence of contractive motor displays (contractive vs. neutral displays: Hedges’s g = 0.45) rather than the presence of expansive displays (expansive vs. neutral displays: g = 0.06). The findings stand as a corrective to previous research, as they indicate that it is the absence of contractive displays rather than the presence of expansive displays that alters affective and behavioral responding. Future research should include neutral control groups, use different methods to assess hormonal change, and investigate these effects in the context of ideographic goals.

This meta-analysis summarizes the results of research on the relationships of majority group members’ endorsement of assimilation, colorblindness, multiculturalism, and the relative relationships of colorblindness and multiculturalism to ethnic prejudice. Random effects analyses found that assimilation was positively related to explicit prejudice ( g. = 0.80), multiculturalism was negatively related to both explicit ( g. = −0.26) and implicit prejudice ( g. = −0.19), and colorblindness was negatively related to explicit prejudice ( g. = −0.07). Multiculturalism was more closely associated with low prejudice than colorblindness ( g. = 0.15). Effect sizes varied as a function of methodology (experimental vs. correlational), country in which research was conducted (United States vs. other countries), and, in experimental studies of multiculturalism, type of prime used (abstract vs. concrete). Discussion points include methodological issues, groups used as targets of prejudice, national diversity norms, additional issues raised in the studies reviewed, and directions for future research.

The Relationship

Abstract To understand the mechanisms underlying narrative persuasion, a growing body of theoretical and empirical work suggests that narratives reduce audience resistance, possibly via narrative engagement. To synthesize this research, we performed a two-part meta-analysis using three-level random-effects models. Part I focused on experimental studies that directly compared narratives and non-narratives on resistance. Based on 15 effect sizes from nine experimental studies, the overall effect size was d = −.213 (equivalent r = −.107; p < .001), suggesting that narratives generated less resistance than non-narratives. Part II was a synthesis of studies of the relationship between narrative engagement and resistance, consisting of 63 effect sizes from 25 studies. Narrative engagement and resistance were negatively correlated (r = −.131; p < .001), and this relationship was moderated by narrative message characteristics, including genre, length, medium, and character unit. Implications of our findings and directions for future research are discussed.
