Problematic Internet use (PIU) can lead to dysfunction and undesired consequences, especially in adolescents and youths. Preventive interventions can reduce them, but should be built on sound evidence. This review synthesizes the available evidence on the effectiveness of primary prevention programs for PIU in adolescents and youths. It adds to previous reviews by broadening the search to general and specific problematic behavior. Two independent reviewers performed a systematic search for published studies on PIU and internet addiction in English, French and Spanish using PubMed, PsycINFO, Cochrane Register of Controlled Trials, and Scopus. Published experimental and quasi-experimental studies that assessed the effectiveness of primary prevention programs targeting PIU behaviors were considered for inclusion. Full texts for eligible studies were retrieved and assessed for quality. Five studies were retained for narrative synthesis. Three of them based the intervention strategy on an underlying theory, one on media literacy, and one used an educational-based approach. A meta-analysis showed that all five interventions were effective in preventing internet addiction separately. However, when using the Hartung-Knapp-Sidik-Jonkman (HKSJ) estimator and removing one of the studies because of a disproportionate Hedges’ g, combined effects were no longer significant. Although PIU is a popular topic, little is known about ways to prevent it. This review demonstrates that prevention programs can be based on different theoretical approaches, but that the available evidence is too heterogeneous to derive generalizable conclusions concerning their effectiveness.

The problematic Internet use (PIU) has become a topic of special relevance since it is a problem that affects the whole world. It has been detected that the population at greatest risk is university students along with adolescents. At the same time, Spain is one of the countries with the highest PIU rate. The purposes of this article were to analyze the presence and degree of Internet addiction among university students and to check the sociodemographic factors that influence the PIU. To this end, 13 hypotheses were put forward and contrasted using a structural equation model. The study adopted a cross-sectional approach by applying the Internet addiction test to a sample of undergraduate students in southern Spain ( n = 1,013). The results indicated a prevalence of PIU among students of almost 12.5% and with a moderate degree of addiction. In turn, the following hypotheses that had a significant effect on the PIU were supported: gender; field of knowledge; living in the parents’ home; Internet daily use for leisure; Internet daily use for academic purposes; number of social networks; sexual orientation; marital status. Finally, the main findings of the study were reviewed, and the main recommendations and implications for mitigating the negative effects of technology and enhancing the positive ones were established.

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.

Mental Well Being

Objective: Psychological well-being has been associated with desirable individual and organisational outcomes. This systematic review aims to assess the effectiveness of digital interventions for the improvement of psychological well-being and/or the prevention/management of poor mental well-being in the workplace. Methods: This review protocol is registered in PROSPERO (CRD42019142428). Scientific databases including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials (CENTRAL) and EMBASE will be searched for relevant studies published between January 1990 and July 2019. Studies will be included if they report specific primary and secondary outcomes of digital interventions delivered to adults in the workplace for the improvement of their psychological wellbeing and/or the prevention/management of poor mental well-being and were published in English. Following screening of titles and abstracts, full texts of potentially eligible papers will be screened in duplicate to identify studies that assess the effectiveness of those digital interventions. Discrepancies will be resolved through consensus or by consulting a third reviewer. An integrated narrative synthesis will assess included studies’ findings, and a meta-analysis will be performed if included studies appear to be homogeneous. The “Cochrane Collaboration’s Risk of Bias” tool and the JBI (Joanna Briggs Institute) Critical Appraisal Checklist for Quasi-Experimental Studies will be used to appraise included studies. Conclusion: The results of this work will provide recommendations on the use of digital interventions for the promotion of psychological well-being at work. It will also guide the development of future workplace digital interventions and subsequent primary research in this field.

During the practicum, pre-service teachers (PSTs) practice instructional skills such as lesson planning and clarity of instruction. Different approaches to assisting PSTs with coaching, mentoring, or supervision have been developed to improve PSTs’ instructional skills during the practicum. We conducted a meta-analysis based on quasi-experimental and experimental control group design studies. The results showed a small and significant overall effect on instructional skills (d = .41). Cooperating teachers’ or supervisors’ cognitive modeling (i.e., making cognitive processes explicit in demonstrating teaching-related practices) of lesson planning and teaching practices based on the cognitive apprenticeship framework was a significant moderator (d = .89).

Objective The aim of this study was to investigate the effectiveness of occupational therapist-/physiotherapist-guided fatigue self-management for individuals with chronic conditions. Methods Eight databases, including MEDLINE and EMBASE, were searched until September 2019 to identify relevant studies. Randomised controlled trials and quasi-experimental studies of self-management interventions specifically developed or delivered by occupational therapists/physiotherapists to improve fatigue symptoms of individuals with chronic conditions were included. A narrative synthesis and meta-analysis were conducted to determine the effectiveness of fatigue self-management. Results Thirty-eight studies were included, and fatigue self-management approaches led by occupational therapists/physiotherapists were divided into six categories based on the intervention focus: exercise, energy conservation, multimodal programmes, activity pacing, cognitive-behavioural therapy, and comprehensive fatigue management. While all exercise programmes reported significant improvement in fatigue, other categories showed both significant improvement and no improvement in fatigue. Meta-analysis yielded a standardised mean difference of the overall 13 studies: 0.42 (95% confidence interval:−0.62 to − 0.21); standardised mean difference of the seven exercise studies was −0.55 (95% confidence interval: −0.78 to −0.31). Discussion Physical exercises inspired by the self-management principles may have positive impacts on fatigue symptoms, quality of life, and other functional abilities.

Positive Effect

Stratified teaching is an effective method and means to implement teaching students per their aptitude. Domestic and foreign scholars have carried out many experimental and quasi-experimental studies to observe the impact of stratified teaching on students’ academic performance, but the results are quite different. So, can stratified teaching effectively help Chinese students improve their academic performance? How big is its impact? Which model is more suitable for Chinese students? To answer these questions, this article uses meta-analysis to quantitatively analyze 22 Chinese studies on the impact of Stratified teaching on student academic performance. We found that (i) stratified teaching has a positive effect on students’ academic performance, and the overall combined effect size is 0.53; (ii) among the seven subjects of mathematics, English, physics, chemistry, biology, geography, and information technology, stratified teaching has had a positive effect on their learning. Stratified teaching’s order of effect on different subjects was English > Physics > Geography > Information Technology > Mathematics > Biology > Chemistry; (iii) stratified teaching is suitable for students of different sizes of classrooms. However, the smaller the number of students in the classroom, the better the learning effect, and (iv) stratified teaching is more suitable for improving their learning in the mobile learning system.
