PONE-D-21-38702I love the way you love me: Responding to partner’s love language preferences boosts satisfaction in romantic heterosexual couplesPLOS ONE

Dear Dr. Stolarski,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please provide the following information/changes:

Methods: Questionnaires:. Provide information about the dates on which the questionnaire was applied on the average time spent on responses (discuss whether there could have been condescending responses and other response biases), and whether there were several attention checks. Clarify if there were payments to participants as a way to encourage participation.

In research in which self-response questionnaires are used, there could have been condescending responses and other response biases related to the social desirability.  The results of online surveys may be affected by bias due for example to low response rates, to a self-selection linked to the salience of a topic, the length of time required to complete the survey, the presentation of the questionnaire, the contact delivery modes, the use of pre-notifications and the presence of incentives. Furthermore, in online surveys, subjects often have greater self-disclosure. The results of the web-based surveys must consider all these aspects to be considered valid and reliable.  Moreover, about bias in participation, note the possible self-selection bias and the nonprobability sampling used to select the participants. See for example Van de Mortel, T.F. Faking it: Social desirability response bias in self-report research. Aust. J. Adv. Nurs. 2008, 25,40. Please provide information about this topic on methods section.

Did you have any missing data or did everyone answer all the questions? If you did have missing data, how did you treat the "missingness"?

Please submit your revised manuscript by May 19 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.
