Little research has been conducted to assess which specific databases should be searched when performing a systematic review (SR) on acupuncture. The current study aimed to identify key databases and the optimal database combination to retrieve randomized controlled trials (RCTs) on acupuncture for inclusion in SRs. A systematic search for SRs in…

Behavioral and social sciences randomized controlled trials (BSSTs) have a significant role in life sciences. Choosing an appropriate control or comparator group for BSSTs is critical, to provide true intervention effects. The objective of this study was to determine the types of control groups used in BSSTs, and the rationale provided to justify…

Albanese, Emiliano; Bütikofer, Lukas; Armijo-Olivo, Susan; Ha, Christine; Egger, Matthias – Research Synthesis Methods, 2020
Background: There is an agreement that the methodological quality of randomized trials should be assessed in systematic reviews, but there is a debate on how this should be done. We conducted a construct validation study of the Physiotherapy Evidence Database (PEDro) scale, which is widely used to assess the quality of trials in physical therapy…

Lohr, Sharon L.; Zhu, Xiaoshu – Sociological Methods & Research, 2017
Many randomized experiments in the social sciences allocate subjects to treatment arms at the time the subjects enroll. Desirable features of the mechanism used to assign subjects to treatment arms are often (1) equal numbers of subjects in intervention and control arms, (2) balanced allocation for population subgroups and across covariates, (3)…

Hassan, N. M.; Landorf, K. B.; Shields, N.; Munteanu, S. E. – Journal of Intellectual Disability Research, 2019
Background: People with intellectual disabilities (ID) often do not meet recommended guidelines for physical activity. The aim of this study was to systematically review available evidence that evaluated the effectiveness of interventions to increase physical activity in individuals with ID. Method: Five electronic databases (MEDLINE, CINAHL,…

Clunie, Lauren; Morris, Neil P.; Joynes, Viktoria C. T.; Pickering, James D. – Anatomical Sciences Education, 2018
Anatomy education is at the forefront of integrating innovative technologies into its curricula. However, despite this rise in technology numerous authors have commented on the shortfall in efficacy studies to assess the impact such technology-enhanced learning (TEL) resources have on learning. To assess the range of evaluation approaches to TEL…

Social cognitive theory (SCT) is a well-known theory for designing nutrition education and physical activity programs for adolescents. This systematic review aimed to evaluate the efficacy of intervention studies based on SCT in reducing or preventing overweight and obesity in adolescents. An electronic literature search in PubMed-Medline, Web of…

Waffenschmidt, Siw; Guddat, Charlotte – Research Synthesis Methods, 2015
Background: It is unclear which terms should be included in bibliographic searches for randomized controlled trials (RCTs) of drugs, and identifying relevant drug terms can be extremely laborious. The aim of our analysis was to determine whether a bibliographic search using only the generic drug name produces sufficient results for the generation…

Castleman, Benjamin L.; Page, Lindsay C. – Society for Research on Educational Effectiveness, 2013
Research has shown that low-income students especially struggle with evaluating financial aid offers and completing all necessary requirements to enroll after paying a deposit to a particular college in the spring (Authors, 2009). Motivated by these empirical results, the authors conducted three studies that showed students who were explicitly…
