The Relationship

Theoretical studies propose an association between family violence and low self-control in adolescence; however, empirical findings of this association are inconclusive. The aim of the present research was to systematically summarize available findings on the relation between family violence and self-control across adolescence. We included 28 studies with 143 effect sizes, representing more than 25,000 participants of eight countries from early to late adolescence. Applying a three-level meta-analysis, taking dependency between effect sizes into account while retaining statistical power, we examined the magnitude and direction of the overall effect size. Additionally, we investigated whether theoretical moderators (e.g., age, gender, country), and methodological moderators (e.g., time lag between family violence and self-control, informant) influenced the magnitude of the association between family violence and self-control. Our results revealed that family violence and self-control have a small to moderate significant negative association (r = −0.191). This association did not vary across gender, country, and informants. The strength of the association, however, decreased with age and in longitudinal studies. This finding provides evidence that researchers and clinicians may expect low self-control in the wake of family violence, especially in early adolescence. Recommendations for future research in the area are discussed.

Theoretical studies propose an association between family violence and low self-control in adolescence, yet empirical findings of this association are inconclusive. The aim of the present research was to systematically summarize available findings on the relation between family violence and self-control across adolescence. We included 27 studies with 143 effect sizes, representing more than 25,000 participants of eight countries from early to late adolescence. Applying a multi-level meta-analyses, taking dependency between effect sizes into account while retaining statistical power, we examined the magnitude and direction of the overall effect size. Additionally, we investigated whether theoretical moderators (e.g., age, gender, country), and methodological moderators (cross-sectional/longitudinal, informant) influenced the magnitude of the association between family violence and self-control. Our results revealed that family violence and self-control have a small to moderate significant negative association (r = -.191). This association did not vary across gender, country, and informants. The strength of the association, however, decreased with age and in longitudinal studies. This finding provides evidence that researchers and clinicians may expect low self-control in the wake of family violence, especially in early adolescence.

The Relationship

Reduced specificity of autobiographical memory has been well established in depression, but whether this ‘overgenerality’ extends to future thinking has not been the focus of a meta-analysis. Following a preregistered protocol, we searched six electronic databases, Google Scholar, personal libraries, and contacted authors in the field for studies matching search terms related to depression, future thinking, and specificity. We reduced an initial 7,332 results to 46 included studies, with 89 effect sizes and 4,813 total participants. Random effects meta-analytic modelling revealed a small but robust correlation between reduced future specificity and higher levels of depression (r = .13, p < .001). Of the 11 moderator variables examined, the most striking effects related to the emotional valence of future thinking (p < .001) and the sex of participants (p = .025). Namely, depression was linked to reduced specificity for positive (but not negative or neutral) future thinking, and the relationship was stronger in samples with a higher proportion of males. This meta-analysis contributes to our understanding of how prospection is altered in depression and dysphoria and, by revealing areas where current evidence is inconclusive, highlights key avenues for future research.

Attitude Toward Science

Science education is attracting increasing attention and many researchers focus on the issue about the attitude-achievement relationship in science, but there is still no consistent conclusion. By using a three-level meta-analytic approach, the aim of the current study was to investigate the relationship between attitude toward science and academic achievement in learning science among primary and secondary school students, and to explore if some study characteristics could have contributed to the inconsistent findings with regard to this relationship as observed in the research literature. A total of 37 studies with 132 effect sizes involving a total of 1,042,537 participants were identified. The meta-analytic results revealed that there was an overall positive and moderate relationship between attitude toward science and learning achievement in science (r = 0.248, p &lt; 0.001). The results further found that this association was moderated by the type of attitude and larger effect sizes were shown in self-efficacy than in interest, societal relevance of attitude toward science, and mixed attitude. Moreover, the effect sizes of studies with unstandardized measure to assess science achievement were larger than those with standardized measure. Possible explanations for these findings and its implications for future research directions were also discussed in this review.

A meta-analysis of research examining the relationships between multidimensional perfectionism and burnout is provided. In doing so, relationships before and after controlling for the relationship between dimensions of perfectionism were examined along with whether relationships were moderated by domain (work, sport, or education). A literature search yielded 43 studies (N = 9,838) and 663 effect sizes. Meta-analysis using random-effects models revealed that perfectionistic strivings had small negative or non-significant relationships with overall burnout and symptoms of burnout. By contrast, perfectionistic concerns displayed medium-to-large and medium positive relationships with overall burnout and symptoms of burnout. After controlling for the relationship between dimensions of perfectionism, "pure" perfectionistic strivings displayed notably larger negative relationships. In terms of moderation, in some cases, perfectionistic strivings were less adaptive and perfectionistic concerns more maladaptive in the work domain. Future research should examine explanatory mechanisms, adopt longitudinal designs, and develop interventions to reduce perfectionistic concerns fueled burnout.

AbstractBackground and aimsThis study examined the relationship between self-reported symptoms of morbid exercise behaviour (MEB) and eating disorders (ED) using meta-analytic techniques.MethodsWe systematically searched MEDLINE, PsycINFO, Web of Science, SciELO and Scopus. Random effects models were used to compute pooled effect sizes estimates (r). The robustness of the summarized estimates was examined through sensitivity analyses by removing studies one at a time.ResultsSixty-six studies comprising 135 effect-sizes (N = 21,816) were included. The results revealed: (a) small-sized relationship in the case of bulimic symptoms (r = 0.19), (b) small- (r = 0.28) to medium-sized relationships (r = 0.41) in the case of body/eating concerns, and (c) medium-sized relationships in the case of overall ED symptoms (r = 0.35) and dietary restraint (r = 0.42). Larger effect sizes were observed in the case of overall ED symptoms in clinical, younger, and thinner populations, as well as when employing a continuously-scored instrument for assessing ED or the Compulsive Exercise Test for assessing MEB. Larger effect sizes were also found in female samples when the ED outcome was dietary restraint.ConclusionsThe identified gaps in the literature suggest that future research on the topic may benefit from: (a) considering a range of clinical (in terms of diagnosed ED) and non-clinical populations from diverse exercise modalities, (b) addressing a wide range of ED symptomatology, and (c) employing longitudinal designs that clarify the temporal direction of the relationship under consideration.

A growing body of literature is exploring the link between social support and international students’ psychological adjustment. So far, however, there has been no systematic assessment of the overall relationship, and no indication which types and sources of social support may be most strongly associated with psychological adjustment. Our meta-analysis of 257 effect sizes across 76 studies fills this gap and assesses (a) the magnitude of the overall association between social support and international students’ psychological adjustment, (b) how different types (subjective, objective, and mixed) and sources (host, conational, international, mixed, and unspecified) of social support moderate the relationship between social support and psychological adjustment, and (c) whether the relationship between social support and psychological adjustment holds across different operationalizations of psychological adjustment. We find a positive overall association ( r = .20, 95% confidence interval [CI] = [0.16, 0.23]) between social support and international students’ psychological adjustment. Types and sources of social support matter as well: Subjective social support relates more strongly to psychological adjustment than objective social support. The data revealed that only support from mixed sources (i.e., not distinguishing between internationals, host, or conationals) is associated with a stronger effect of social support than support from conationals or from fellow international students (compared with support from host sources). We find no differences in the relation between social support and positive or negative adjustment. We outline recommendations for future research based on the meta-analysis.

This study investigates the stability of self-control by examining whether neighborhood composition conditions the effect of self-control on offending. Congruent with social learning perspectives, I argue that neighborhood behavioral models provide a conduit for the expression of one’s self-control. Using data from the Project of Human Development in Chicago Neighborhoods (PHDCN), I examine multi-level zero-inflated negative binomial models that include cross-level interactions between self-control and aggregate self-control. I found that for the frequency of delinquency, but not serious offending, the effect of low self-control is amplified in neighborhoods identified as having low aggregate self-control. These findings provide evidence that the effect of low self-control on offending is not always invariant across neighborhoods.

The Relationship

Purpose Though the effect of transformational leadership (TFL) on followers has been largely examined in hospitality, the findings are rather inconsistent. This paper aims to provide a quantitative review for the relationship between TFL and follower outcomes in hospitality and a detailed analysis of the moderating variables (cultural differences, measurement instrument, rating sources and time lag). Design/methodology/approach To explore the effect sizes of TFL on followers, this study conducted a quantitative meta-analysis based on 62 primary studies, including 66 independent samples (N = 23,037). The outcomes of TFL were categorized into subordinates’ attitudinal outcomes, relational perceptions and behavioral outcomes. Findings The results indicate that TFL has the strongest impact on relational perceptions, followed by subordinates’ attitudinal and behavioral outcomes. The results also show that cultural differences, rating sources and time lag partially moderate the relationships between TFL and follower outcomes. Research limitations/implications TFL generally has a high level of validity for explaining attitudinal, behavioral and relational perception outcomes of followers in the field of hospitality. Given that, there have been a large number of studies investigating TFL with follower attitudinal and behavioral outcomes, it might not be necessary to continue applying identical frameworks to investigate the effect of TFL. Instead, future research on TFL is expected to explore the relationship between TFL and followers’ relational perceptions and consider cultural and methodological factors. Originality/value To the best of authors’ knowledge, this is the first meta-analysis to clear theoretical links between TFL and its outcomes in the hospitality context. This study further investigates several moderators that can influence the effects of TFL and helps better understand the influence of TFL in the area of hospitality. The study also provides future research directions for leadership research in the hospitality context.
