Depressive symptoms (CES-D) and activities of daily living (ADL)\/instrumental ADL (IADL) limitations were measured at every wave. Complementary actor\u2013partner interdependence models (APIM) and random-intercept cross-lagged panel models (RI-CLPM) were applied, with multiplicity adjustment, full-information maximum likelihood (FIML), and 20-imputation triangulation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726105042_sec3\" sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Within-couple correlations of depressive symptoms were positive in every cohort (\n                      <jats:italic>r<\/jats:italic>\n                      \u00a0=\u00a00.34\u20130.43 in CHARLS, 0.14\u20130.20 in HRS, 0.23\u20130.29 in ELSA). APIM partner effects were robust in CHARLS but sparse elsewhere. After partialling out stable between-couple similarity, RI-CLPM within-person cross-spouse associations were attenuated, reaching consistent significance under FIML and multiple imputation only in ELSA. Four-variable RI-CLPMs showed bidirectional depression\u2013disability coupling, strongest in HRS and ELSA, with cross-spouse function-to-depression effects in Western cohorts but not in CHARLS. Sex distinguishability was not supported, and half-longitudinal mediation through ADL\/IADL did not survive multiplicity correction.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726105042_sec4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Concordance in late-life depressive symptoms replicates across three major aging cohorts; in CHARLS, it primarily reflects stable between-couple similarity, whereas modest within-person prospective coupling persists in ELSA and in the multiple-imputation HRS estimates.
