Manuscripts Submission Guidelines:
Length: Regular articles are limited to 30 pages, meta-analyses to 35 pages, and brief reports to 12 pages. The page limit includes all parts of the manuscript, including the title page, abstract, text, references, tables, and figures. Use a sans serif font such as 11-point Calibri or 11-point Arial, or a serif font such as 12-point Times New Roman, and double-space the text. Authors may request permission to exceed the page limit, but the journal operates under a contractual page budget, so overages are allowed only when necessary. Please write succinctly and place nonessential materials in a supplement, not in the manuscript. Title Page: The title page should adhere to APA Style and include an APA-style Author Note. The manuscript’s title should be no more than 12 words long, and it should not state an assertion or conclusion. The title should include “a randomized controlled trial,” “a meta-analysis,” “a systematic review,” or “systematic review and meta-analysis,” if appropriate.APA-Style Author Notes include the following information:• Paragraph 1: All authors should have reviewed and agreed to their individual contribution(s) before submission. Authors may claim credit for more than one role, and the same role can be attributed to more than one author.• Paragraph 2: Changes, if any, in author affiliations that occurred after the study ended.• Paragraph 3: Disclosures and acknowledgements, if any.• Paragraph 4: Corresponding author’s contact information, including an email address. Abstract: Empirical reports must include a structured abstract with < 250 words and these headings:• Objective: Brief statement of the purpose or aims of the study.• Methods: Essential information about the study design, procedures, and measures.• Results: Primary findings; include sample size and primary statistical results, if possible.• Conclusions: Main conclusions based on the primary findings. Keywords: List up to five keywords below the abstract. Body of the Manuscript: Empirical reports should include:• a clear statement of the research question, hypothesis, specific aims, or purpose of the study;• essential information about the methods even if a separate methods or protocol paper is cited;• descriptive statistics to characterize the sample, the sample size, and the measures;• a CONSORT-style participant flow diagram, if appropriate;• disclosure of the study’s limitations; and• conclusions that are consistent with the findings. The methods section of reports of research involving human participants must provide information about institutional review board or ethics board approval, including the name(s) of the institution(s) that approved the study, or an explanation of why the study was exempt from approval and oversight. Informed consent and assent procedures should also be briefly described.Reports should explain the significance or novel contribution of original research without overstating the study’s translational, clinical, or public health significance.If the purpose of the work is to attempt to replicate or extend previous studies, this should be disclosed, and minor innovations or superficially novel features should not be overstated.The statistical methods should adhere to the APA Task Force on Statistical Inference guidelines.
