As past studies of self-control and Internet addiction showed mixed results, this meta-analysis of 83 primary studies with 80,681 participants determined whether (a) these students with less self-control had greater Internet addiction, and (b) age, culture, gender, Internet addiction measures, or year moderated these relations. We used a random-effects meta-analysis of Pearson product-moment coefficients r with Fisher’s z-transformation and tested for moderation with the homogeneity tests. The results showed a positive link between impulsivity and Internet addiction (r = 0.371, 95% CI = [0.311, 0.427]) and a negative link between restraint and Internet addiction (r = −0.362, 95% CI = [−0.414, −0.307]). The moderation analysis indicated that the correlation between impulsivity indicators and greater Internet addiction was stronger among undergraduates (18–22 years old) than among adolescents (10–17 years old). Furthermore, the negative link between a restraint indicator and Internet addiction was greater (a) among students in East Asia than those in Western Europe/North America, (b) among males than females and (c) when using the Internet addiction measures GPIUS or IAT rather than CIAS. Hence, these results indicate a negative link between self-control and Internet addiction, and this link is moderated by age, culture, gender, and Internet addiction measure.

AbstractObjectivesThe results of existing studies on bisphenol A (BPA) and puberty timing did not reach a consensus. Thereby we performed this meta-analytic study to explore the association between BPA exposure in urine and puberty timing.MethodsMeta-analysis of the pooled odds ratios (OR), prevalence ratios (PR) or hazards ratios (HR) with 95% confidence intervals (CI) were calculated and estimated using fixed-effects or random-effects models based on between-study heterogeneity.ResultsA total of 10 studies involving 5621 subjects were finally included. The meta-analysis showed that BPA exposure was weakly associated with thelarche (PR: 0.96, 95% CI: 0.93–0.99), while no association was found between BPA exposure and menarche (HR: 0.99, 95% CI: 0.89–1.12; OR: 1.02, 95% CI: 0.73–1.43), and pubarche (OR: 1.00, 95% CI: 0.79–1.26; PR: 1.00, 95% CI: 0.95–1.05).ConclusionsThere was no strong correlation between BPA exposure and puberty timing. Further studies with large sample sizes are needed to verify the relationship between BPA and puberty timing.

The Relationship

Context Infant colic is a common and distressing disorder of early infancy. Its etiology is unknown, making treatment challenging. Several articles have suggested a link to migraine. Objective The objective of this article was to perform a systematic review and, if appropriate, a meta-analysis of the studies on the relationship between infant colic and migraine. Data sources Studies were identified by searching PubMed and ScienceDirect and by hand-searching references and conference proceedings. Study selection For the primary analysis, studies specifically designed to measure the association between colic and migraine were included. For the secondary analysis, studies that collected data on colic and migraine but were designed for another primary research question were also included. Data extraction Data were abstracted from the original studies, through communication with study authors, or both. Two authors independently abstracted data. Main outcomes and measures The main outcome measure was the association between infant colic and migraine using both a fixed-effects model and a more conservative random-effects model. Results Three studies were included in the primary analysis; the odds ratio for the association between migraine and infant colic was 6.5 (4.6–8.9, p < 0.001) for the fixed-effects model and 5.6 (3.3–9.5, p = 0.004) for the random-effects model. In a sensitivity analysis wherein the study with the largest effect size was removed, the odds ratio was 3.6 (95% CI 1.7–7.6, p = 0.001) for both the fixed-effects model and random-effects model. Conclusions In this meta-analysis, infant colic was associated with increased odds of migraine. If infant colic is a migrainous disorder, this would have important implications for treatment. The main limitation of this meta-analysis was the relatively small number of studies included.

The Relationship

There are three hypotheses regarding the relationship between Self-Concept Clarity (SCC) and Internet use. It was argued that Internet use: 1) decreases SCC, 2) increases SCC, 3) does not relate with SCC. The present study, in the form of a systematic and meta-analytic synthesis, aimed to explore: a) the extent empirical evidence can support each hypothesis; b) how Internet use-SCC relationship was addressed across studies; c) the intensity of the Internet use –SCC relationship; d) potential moderators. Twenty-one studies (N = 8,910) met the inclusion criteria for the systematic review (i.e., being quantitative, written in English, concerned with Internet use -SCC relationship) and 11 studies (N = 3,298) met the additional criteria for meta-analysis (i.e., being correlational, using self-evaluation instruments, quantifying general Internet use and including the information needed to calculate the meta-analysis specific indicators). Results emphasized that all three hypotheses are plausible, as distinct dimensions of Internet use related differently with SCC. However, the conclusions were limited by the extensive use of cross-sectional design. For general Internet use and SCC relationship the overall effect was -0.350, p < .01. Some moderators were significant: cultural background, Internet operationalization, age homogeneity, participants rewarding. This paper outlines the complexity of SCC – Internet relationship and underlines some of the gaps that should be further addressed. Implications and limits of the study (e.g., publication bias, excluded outcomes in the meta-analysis or possible omission of moderators) are discussed.

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 &lt; .001). Of the 11 moderator variables examined, the most striking effects related to the emotional valence of future thinking (p &lt; .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.

The Relationship

This study evaluates the relationship between Internet addiction and academic performance among students of eight Afghan universities. The differences between internet addiction in terms of gender was also identified. The survey/research method adopted the Internet Addiction Test (IAT) based on Young’s survey applied with some modifications. From 1000 distributed questionnaires only 976 participants (358 females, and 618 males) were responded completely. The descriptive analysis was used to identify the demographic characteristics of student’s Internet usage profile. The independents sample t-test was performed to determine the differences in the level of Internet addiction in terms of gender. Statistical significance was set at a value of p <0.01. Likewise, the correlation test was implemented to identify the relationship between Internet addiction and academic performance, with referencing of sample. The results indicated that statistically there is a significant correlation among Internet addiction and academic performance. Results also indicated that statistically there were significant differences between Internet addictions in terms of demographic characteristics. This study suggests that future researchers need to work on large sample while conducting the related research. It emphasizes that students should concentrate more on their academic activities than spending time on unnecessary Internet surfing. Findings also revealed that, in Afghanistan the problem of Internet addiction is not a serious challenge, but this information should be disseminated among undergraduate university students to stop the indulgent in using the Internet.

Smartphones are a fundamental part of emerging adults' life. The aim of this chapter is to determine which factors play a role in “phubbing” during emerging adulthood as well as to propose and test a model of this phenomenon. We tested a model of relations between phubbing, self-esteem, self-control, well-being, and internet addiction. The following measures were used: the Rosenberg Self Esteem Scale, the Brief Self-Control Scale (BSCS), the Flourishing Scale, the Internet Addiction Scale, and the Phubbing Scale. The participants in the online study were 640 Italian emerging adults (526 females and 114 males), ranging in age from 18 to 29 (M = 21.7, SD = 2.18). The results showed that the model was well fitted, particularly in postulating that a decrease in the level of self-control is related to an increase in Internet addiction, that an increase in Internet addiction increases the probability of phubbing behavior, and that the level of self-esteem and well-being do not affect Internet addiction. Gender differences, in favor of males, occurred only in self-esteem.

Sex And Age Differences

Background and aim The diagnosis of embolic stroke of undetermined source (ESUS) is based on excluding other more likely stroke etiologies, and therefore diagnostic testing plays an especially crucial role. Our objective was to compare the diagnostic testing by region, sex, and age among the participants of NAVIGATE-ESUS trial. Methods Participants were grouped according to five global regions (North America, Latin America, Western Europe, Eastern Europe and East Asia), age (<60, 60–74, and >75 years), and sex. Frequencies of each diagnostic test within areas of echocardiography, cardiac rhythm monitoring, and arterial imaging were described and compared across groups. A multivariable logistic regression model for each diagnostic test was fit to assess the independent influence of each of region, age, and sex and likelihood of testing. Results We included 6985 patients in the analysis (918 from North America; 746 from Latin America; 2853 from Western Europe; 1118 from Eastern Europe; 1350 from East Asia). Average age (highest in Western Europe (69 years), lowest in Eastern Europe (65 years)), % females (highest in Latin America (44%) and lowest in East Asia (31%)), and use of each diagnostic test varied significantly across regions. Region, but not sex, was independently associated with use of each diagnostic test examined. Transesophageal echocardiography and either CT or MR angiogram were more often used in younger patients. Conclusion Diagnostic testing differed by region, and less frequently by age, but not by sex. Our findings reflect the existing variations in global practice in diagnostic testing in ESUS patients.

The relationship between emotion management skills and the use of the Internet was examined in this study to determine whether or not the emotion management skills of university students are a predictor of Internet addiction. The study was conducted in the 2008/2009 academic year with 345 students from different departments of a university in Turkey. Data were collected using the Emotion Management Skills Inventory (Çeçen, 2006) and the Problematic Internet Usage Scale (Ceyhan, Ceyhan, & Gürcan, 2007). Results of regression analysis showed that the total measure of emotion management skills predicted the levels of Internet addiction.

The Relationship

Purpose The purpose of this paper is to investigate whether the effectiveness of transformational leadership behaviors are moderated by a country’s cultural values and cultural practices. Design/methodology/approach The authors describe a meta-analytic review of the relationship between transformational leadership and employee performance (task performance and OCBs) using data from over 57,000 individuals, 215 samples and 34 countries. The authors examine whether this relationship is moderated by the cultural values and practices of the country in which the study was located – after first controlling for methodological factors. Findings The authors find that cultural values and practices moderate the transformational leadership – employee performance relationship such that the relationship is much stronger in countries whose culture is incongruent with transformational leadership. Research limitations/implications Data were only available for 34 countries and it is unclear what role industry type and job type play in determining transformational leadership effectiveness or if these situational variables are confounded with culture. The findings call into question the generalizability of transformational leadership across countries and cultures. Practical implications The findings suggest that the value of transformational leadership behaviors may be limited in developed economies such as Western Europe and North America, while transformational leadership is most effective in Africa, the Middle East, South America and parts of Southeast Asia. Originality/value This is the first paper to examine the generalizability of transformational leadership across 34 countries and is by far the largest review ever conducted into the relationship between transformational leadership and subordinate performance.
