A Scoping Review of dating behaviours in typically developing adults

Reviewers will use Covidence to organize their work. Two reviewers will independently screen the titles/abstracts for 20% of studies for inclusion.

If Kappa scores are 0.8 or above, one author will continue to review.

If Kappa scores are below 0.8, all articles will be reviewed by a second team member, with disagreements resolved through consensus.

If consensus is not achieved, a third reviewer will act as moderator. The same process will then be repeated for full-text appraisal.

An extraction tool will be developed with all authors based on the research questions.

The tool will be piloted on several articles and discussed with the team and any revisions to the tool completed at that time.

A single reviewer will extract study data, with a second reviewer appraising 20% of the studies to ensure reliability.

Disagreements will be discussed to reach consensus, with a third reviewer acting as moderator if consensus is not achieved.

Data extraction will include:

• Author/s
• Year of publication
• Study aims/purpose
• Country
• Number of participants (and sample)
• Number of males and females
• Ethnicity
• Study design
• Theories underpinning study
• Identify nonverbal and verbal behaviours
• Any associations or predictive models explaining the links between behaviours
• Outcome measures (name of)

Missing details will be coded as “not present”.

The data obtained from eligible papers will be summarized descriptively. We will count and compare them directly.
