Manuscripts should be the appropriate length for the material being presented. Manuscripts can vary from a maximum of 4,500 words for a brief report to 10,500 words for a larger research report to 15,000 words for a report containing multiple studies or comprehensive longitudinal studies. Please note that the total length includes the cover page, abstract, main manuscript text, references section, tables, and figures. Editors will decide on the appropriate length and may return a manuscript for revision before reviews if they think the paper is too long. Please make manuscripts as brief as possible. We have a strong preference for shorter papers.

The APA Publication Manual (7th ed.opens in new window) stipulates that "authorship encompasses…not only persons who do the writing but also those who have made substantial scientific contributions to a study." In the spirit of transparency and openness, this journal has adopted the Contributor Roles Taxonomyopens in new window (CRediT) to describe each author's individual contributions to the work. CRediT offers authors the opportunity to share an accurate and detailed description of their diverse contributions to a manuscript.

Submitting authors will be prompted to select one or more contributor roles for each author at initial submission. All authors should have reviewed and agreed to their individual contribution(s) before submission. If the manuscript is accepted for publication, an Author Contributions Statement will be generated during the typesetting process and published in the author note of the final article. It is not necessary for authors to provide a written Author Contributions Statement upon submission.

CRediT includes 14 contributor roles, as described below:

• Conceptualization: Ideas; formulation or evolution of overarching research goals and aims.
• Data curation: Management activities to annotate (produce metadata), scrub data and maintain research data (including software code, where it is necessary for interpreting the data itself) for initial use and later reuse.
• Formal analysis: Application of statistical, mathematical, computational, or other formal techniques to analyze or synthesize study data.
• Funding acquisition: Acquisition of the financial support for the project leading to this publication.
• Investigation: Conducting a research and investigation process, specifically performing the experiments, or data/evidence collection.
• Methodology: Development or design of methodology; creation of models.
• Project administration: Management and coordination responsibility for the research activity planning and execution.
• Resources: Provision of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computing resources, or other analysis tools.
• Software: Programming, software development; designing computer programs; implementation of the computer code and supporting algorithms; testing of existing code components.
• Supervision: Oversight and leadership responsibility for the research activity planning and execution, including mentorship external to the core team.
• Validation: Verification, whether as a part of the activity or separate, of the overall replication/reproducibility of results/experiments and other research outputs.
• Visualization: Preparation, creation and/or presentation of the published work, specifically visualization/data presentation.
• Writing—original draft: Preparation, creation and/or presentation of the published work, specifically writing the initial draft (including substantive translation).
• Writing—review and editing: Preparation, creation and/or presentation of the published work by those from the original research group, specifically critical review, commentary or revision—including pre- or post-publication stages.

Authors can claim credit for more than one contributor role, and the same role can be attributed to more than one author. Not all roles will be applicable to any particular scholarly work.

Authors submitting manuscripts to the journal Developmental Psychology are now required to provide 2–3 brief sentences regarding the relevance or public health significance of their study or review described in their manuscript. This description should be included within the manuscript on the abstract/keywords page.

The public significance statement (similar to the Relevance section of NIH grant submissions) summarizes the significance of the study's findings for a public audience in one to three sentences (approximately 30–70 words long). It should be written in language that is easily understood by both professionals and members of the lay public. Please refer to the Guidance for Translational Abstracts and Public Significance Statements page to help you write these statements. This statement supports efforts to increase dissemination and usage of research findings by larger and more diverse audiences.

When an accepted paper is published, these sentences will be boxed beneath the abstract for easy accessibility. All such descriptions will also be published as part of the table of contents, as well as on the journal's web page. This policy is in keeping with efforts to increase dissemination and usage by larger and diverse audiences.

In addition to email addresses, please supply mailing addresses, phone numbers, and fax numbers. Most correspondence will be handled by email. Keep a copy of the manuscript to guard against loss.

This journal uses masked review for all submissions. Make every effort to see that the manuscript itself contains no clues to the authors' identity, including grant numbers, names of institutions providing IRB approval, self-citations, and links to online repositories for data, materials, code, or preregistrations (e.g., Create a View-only Link for a Projectopens in new window). The submission letter should indicate the title of the manuscript, the authors' names and institutional affiliations, and the date the manuscript is submitted.

The first page of the manuscript should omit the authors' names and affiliations but should include the title of the manuscript and the date it is submitted. Author notes, acknowledgments, and footnotes containing information pertaining to the authors' identity or affiliations may be added on acceptance.

Authors should be sure to report the procedures for sample selection and recruitment. Major demographic characteristics should be reported, such as sex, age, socioeconomic status, race/ethnicity, and, when possible and appropriate, disability status and sexual orientation. Even when such demographic characteristics are not analytic variables, they provide a more complete understanding of the sample and of the generalizability of the findings and are useful in future meta-analytic studies.

Authors should provide a justification that their sample size is appropriate beyond just citing convention in the literature. Justification could include a power analysis, a stopping rule, and/or some other type of valid justification.

For all study results, measures of both practical and statistical significance should be reported. The latter can involve either a standard error or an appropriate confidence interval. Practical significance can be reported using an effect size, a standardized regression coefficient, a factor loading, or an odds ratio.

Manuscripts should include information regarding the establishment of interrater reliability when relevant, including the mechanisms used to establish reliability and the statistical verification of rater agreement and excluding the names of the trainers and the amount of personal contact with such individuals.

Authors should review the APA Style Journal Article Reporting Standards (JARS) for quantitative, qualitative, and mixed methods. The standards offer ways to improve transparency in reporting to ensure that readers have the information necessary to evaluate the quality of the research and to facilitate collaboration and replication. The JARS: 

• recommend the division of hypotheses, analyses, and conclusions into primary, secondary, and exploratory groupings to allow for a full understanding of quantitative analyses presented in a manuscript and to enhance reproducibility; 
• offer modules for authors reporting on replications, clinical trials, longitudinal studies, and observational studies, as well as the analytic methods of structural equation modeling and Bayesian analysis; and 
• include guidelines on reporting on of study preregistration (including making protocols public); participant characteristics (including demographic characteristics; inclusion and exclusion criteria) psychometric characteristics of outcome measures and other variables, and planned data diagnostics and analytic strategy. 

JARS-Qual offers guidance to researchers using qualitative methods such as narrative data, grounded theory, phenomenological, critical, discursive, performative, ethnographic, consensual qualitative, case study, psychobiography, and thematic analysis approaches. 

The guidelines focus on transparency in methods reporting, recommending descriptions of how the researcher’s own perspective affected the study, as well as the contexts in which the research and analysis took place. 

Authors should also review the new Journal Article Reporting Standards for Race, Ethnicity, and Culture (JARS–REC). Meant for all authors, regardless of research topic, JARS–REC include standards for all stages of research and manuscript writing, on, for example: 

• Using the title, abstract, and keywords to identify race and ethnicity of participants without signaling Whiteness as default; 
• Discussing the applicability of the theoretical approach to populations for which it was not developed; 
• Addressing limits on generality, recognizing that generalizability is always constrained and is not the primary purpose of every study; and 
• Considering whether findings could be used or misused to cause harm.

APA endorses the Transparency and Openness Promotion (TOP) Guidelines developed by a community working group in conjunction with the Center for Open Science (Nosek et al. 2015opens in new window). Empirical research, including meta-analyses, submitted to Developmental Psychology must at least meet the “requirement” level for all aspects of research planning and reporting. Authors should include a subsection in the method section titled “Transparency and Openness.” This subsection should detail the efforts the authors have made to comply with the TOP Guidelines. 

For example:

• We report how we determined our sample size, all data exclusions (if any), all manipulations, and all measures in the study, and we follow JARS (Appelbaum et al., 2018). All data, analysis code, and research materials are available at [stable link to repository]. Data were analyzed using R, version 4.0.0 (R Core Team, 2020) and the package ggplot, version 3.2.1 (Wickham, 2016). This study’s design and its analysis were not pre-registered.

Authors must state whether data, code, and study materials are posted to a trusted repository and, if so, where to access them, including their location and any limitations on use. If they cannot be made available, authors must state the legal or ethical reasons why they are not available. Trusted repositories adhere to policies that make data discoverable, accessible, usable, and preserved for the long term. Trusted repositories also assign unique and persistent identifiers. Recommended repositories include APA’s repositoryopens in new window on the Open Science Framework (OSF), or authors can access a full list of other recommended repositoriesopens in new window.

In a subsection titled “Transparency and Openness” at the end of the method section, specify whether and where the data and material will be available or note the legal or ethical reasons for not doing so. For submissions with quantitative or simulation analytic methods, state whether the study analysis code is posted to a trusted repository, and, if so, how to access it (or the legal or ethical reason why it is not available).

For example:

• All data have been made publicly available at the [trusted repository name] and can be accessed at [persistent URL or DOI].
• Materials and analysis code for this study are not available because [legal or ethical reason].
• The code behind this analysis/simulation has been made publicly available at the [trusted repository name] and can be accessed at [persistent URL or DOI].

Preregistration of studies and specific hypotheses can be a useful tool for making strong theoretical claims. Likewise, preregistration of analysis plans can be useful for distinguishing confirmatory and exploratory analyses. Investigators are encouraged to preregister their studies and analysis plans prior to conducting the research via a publicly accessible registry system (e.g., OSFopens in new window, ClinicalTrials.gov, or other trial registries in the WHO Registry Network). There are many available templates; for example, APA, the British Psychological Society, and the German Psychological Society partnered with the Leibniz Institute for Psychology and Center for Open Science to create Preregistration Standards for Quantitative Research in Psychologyopens in new window (Bosnjak et al., 2022).

Articles must state whether or not any work was preregistered and, if so, where to access the preregistration. If any aspect of the study is preregistered, include the registry link in the method section. Preregistrations must be available to reviewers; authors may submit a masked copy via stable link or supplemental material. Links in the method section should be replaced with an identifiable copy on acceptance.

For example:

• This study’s design was preregistered; see [STABLE LINK OR DOI].
• This study’s design and hypotheses were preregistered; see [STABLE LINK OR DOI].
• This study’s analysis plan was preregistered; see [STABLE LINK OR DOI].
• This study was not preregistered.

Developmental Psychology publishes direct replications. Submissions should include “A Replication of XX Study” in the subtitle of the manuscript as well as in the abstract.

Developmental Psychology also publishes Registered Reports. Registered Reports require a two-step review process. The first step is the submission of the registration manuscript. This is a partial manuscript that includes hypotheses, rationale for the study, experimental design, and methods. The partial manuscript will be reviewed for rigor and methodological approach.

If the partial manuscript is accepted, this amounts to provisional acceptance of the full report regardless of the outcome of the study. The full manuscript will be reviewed for adherence to the preregistered design (deviations should be reported in the manuscript).

Prepare manuscripts according to the Publication Manual of the American Psychological Association using the 7th edition. Manuscripts may be copyedited for bias-free language (see Chapter 5 of the Publication Manual).

Review APA's Journal Manuscript Preparation Guidelines before submitting your article.

Double-space all copy. Other formatting instructions, as well as instructions on preparing tables, figures, references, metrics, and abstracts, appear in the Manual. Additional guidance on APA Style is available on the APA Style websiteopens in new window.

Below are additional instructions regarding the preparation of display equations, computer code, and tables.

We strongly encourage you to use MathType (third-party software) or Equation Editor 3.0 (built into pre-2007 versions of Word) to construct your equations, rather than the equation support that is built into Word 2007 and Word 2010. Equations composed with the built-in Word 2007/Word 2010 equation support are converted to low-resolution graphics when they enter the production process and must be rekeyed by the typesetter, which may introduce errors.

To construct your equations with MathType or Equation Editor 3.0:

• Go to the Text section of the Insert tab and select Object.
• Select MathType or Equation Editor 3.0 in the drop-down menu.

If you have an equation that has already been produced using Microsoft Word 2007 or 2010 and you have access to the full version of MathType 6.5 or later, you can convert this equation to MathType by clicking on MathType Insert Equation. Copy the equation from Microsoft Word and paste it into the MathType box. Verify that your equation is correct, click File, and then click Update. Your equation has now been inserted into your Word file as a MathType Equation.

Use Equation Editor 3.0 or MathType only for equations or for formulas that cannot be produced as Word text using the Times or Symbol font.

Because altering computer code in any way (e.g., indents, line spacing, line breaks, page breaks) during the typesetting process could alter its meaning, we treat computer code differently from the rest of your article in our production process. To that end, we request separate files for computer code.

In online supplemental material

We request that runnable source code be included as supplemental material to the article. For more information, visit Supplementing Your Article With Online Material.

In the text of the article

If you would like to include code in the text of your published manuscript, please submit a separate file with your code exactly as you want it to appear, using Courier New font with a type size of 8 points. We will make an image of each segment of code in your article that exceeds 40 characters in length. (Shorter snippets of code that appear in text will be typeset in Courier New and run in with the rest of the text.) If an appendix contains a mix of code and explanatory text, please submit a file that contains the entire appendix, with the code keyed in 8-point Courier New.

Use Word's insert table function when you create tables. Using spaces or tabs in your table will create problems when the table is typeset and may result in errors.

Academic writing and English language editing services

Authors who feel that their manuscript may benefit from additional academic writing or language editing support prior to submission are encouraged to seek out such services at their host institutions, engage with colleagues and subject matter experts, and/or consider several vendors that offer discounts to APA authors.

Please note that APA does not endorse or take responsibility for the service providers listed. It is strictly a referral service.

Use of such service is not mandatory for publication in an APA journal. Use of one or more of these services does not guarantee selection for peer review, manuscript acceptance, or preference for publication in any APA journal.

APA holds policies that apply to all journals published. These include policies on author contributorship and responsibilities of authors; author name changes after publication; the use of generative artificial intelligence; funder information and conflict-of-interest disclosures; duplicate publication; data publication and reuse; and preprints. Please also refer to individual journal submission guidance for specific practices and requirements for manuscript submission.

A key convention in the publication of research is the peer review process, in which the quality and potential contribution of each manuscript is evaluated by one's peers in the scientific community. Like other scientific journals, APA journals utilize a peer review process to guide manuscript selection and publication decisions.

In light of changing patterns of scientific knowledge dissemination, APA requires authors to provide information on prior dissemination of the data and narrative interpretations of the data/research appearing in the manuscript (e.g., if some or all were presented at a conference or meeting, posted on a listserv, shared on a website, including academic social networks like ResearchGate, etc.). This information (2–4 sentences) must be provided as part of the author note.

APA policy prohibits an author from submitting the same manuscript for concurrent consideration by two or more publications.

APA requires authors to reveal any possible conflict of interest in the conduct and reporting of research (e.g., financial interests in a test or procedure, funding by pharmaceutical companies for drug research).

APA Journals aims to address systemic inequities and bias, promote equitable opportunities for researchers, and foster an inclusive environment within the psychological research and scholarly publishing communities, representative of the wide array of people that psychology consists of and serves. Please refer to individual journal submission guidance for specific EDI practices and requirements for manuscript submission.

The APA Journals™ Program is committed to publishing transparent, rigorous research; improving reproducibility in science; and aiding research discovery. Open science practices vary across subfields and per editor discretion, and APA Publishing supports all efforts to improve openness and transparency, especially as they improve diversity, equity, and inclusion. Please refer to individual journal submission guidance for specific OS practices and requirements for manuscript submission.

The APA Journals Office supports authors’ choices on how to publish their work. We are committed to offering options that we believe comply with most funder and institutional requirements and support both self-archiving (“green”) and APC (paid for via an article processing charge and also known as “gold”) Open Access options. Submitting a manuscript for peer review is free of charge.

APA’s current policies on generative AI include:

• When a generative AI model is used in the drafting of a manuscript for an APA publication, the use of AI must be disclosed in the methods section and cited.
• AI cannot be named as an author on an APA scholarly publication.

APA policy prohibits an author from submitting the same manuscript for concurrent consideration by two or more publications. Preprints are allowed.

Authors of accepted papers must obtain and provide on final acceptance all necessary permissions to reproduce in print and electronic form any copyrighted work, including test materials (or portions thereof), photographs, and other graphic images (including those used as stimuli in experiments).

On advice of counsel, APA may decline to publish any image whose copyright status is unknown.

It is a violation of APA Ethical Principles to publish “as original data, data that have been previously published” (Standard 8.13).

APA Ethical Principles also state that “after research results are published, psychologists do not withhold the data on which their conclusions are based from other competent professionals who seek to verify the substantive claims through reanalysis and who intend to use such data only for that purpose, provided that the confidentiality of the participants can be protected and unless legal rights concerning proprietary data preclude their release” (Standard 8.14).

APA expects authors to make their data available if asked during the editorial process and for at least five years after the date of publication.

If the manuscript is accepted, the corresponding author is required to sign and submit a Certification of Compliance with APA Ethical Principles (PDF, 26KB).opens in new window
