Participants completed assessments of sleep quality (Pittsburgh Sleep Quality Index) and diet quality (Starting the Conversation on Diet) at baseline, 1-month, and 3-month follow-ups.

Similarly, there were actor and partner effects of sleep quality on self-regulatory effort and self-efficacy. There were significant indirect effects of partners\u2019 sleep quality on the actor\u2019s diet quality through the actor\u2019s self-regulatory effort and self-efficacy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Poor sleep quality has both individual and dyadic associations with diet quality in couples.
