Increasing evidence suggests that dyadic coping\u2014the joint process through which patient\u2013caregiver pairs manage illness-related stress\u2014plays a crucial role in emotional adjustment and relationship quality. Meanwhile, psychological capital (PsyCap), comprising optimism, hope, resilience, and self-efficacy, has been recognized as a key positive psychological resource that enhances adaptation to cancer-related challenges. However, research integrating these two constructs within the lung cancer context remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional study was conducted among 225 lung cancer patient\u2013caregiver dyads recruited from hospitals in Chengdu between January and September 2025. Participants completed the Positive Psychological Capital Questionnaire (PPQ) and the Dyadic Coping Inventory (DCI). Pearson correlation analysis was used to examine bivariate associations, and the Actor\u2013Partner Interdependence Model (APIM) was applied using AMOS 23.0 to explore actor and partner effects between PsyCap and dyadic coping.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant positive correlations were found between patients\u2019 and their caregivers\u2019 PsyCap and dyadic coping (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.01).

The caregiver\u2019s partner effect on the patient\u2019s coping was significant (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u202f=\u202f0.14,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.037), while the reverse effect was not significant.

In the APIM, caregivers\u2019 PsyCap showed a significant partner effect on patients\u2019 dyadic coping, whereas the reverse partner path was not significant. Given the cross-sectional design, these findings should be interpreted as associations rather than causal effects. Longitudinal and intervention studies are needed to determine whether enhancing PsyCap can improve dyadic coping and related psychosocial outcomes in lung cancer dyads.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1940535","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T05:31:03Z","timestamp":1789623063000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A study on the association between psychological capital and dyadic coping among lung cancer patients and their caregivers: an actor\u2013partner interdependence model approach"],"prefix":"10.3389","volume":"17","author":[{"given":"Yan","family":"Li","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Nursing, and Education, MAHSA University","place":["Jenjarom, Selangor, Malaysia"]},{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liu","family":"He","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vimala","family":"Ramoo","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Nursing, and Education, MAHSA University","place":["Jenjarom, Selangor, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingling","family":"Zeng","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gek Mui","family":"Lim","sequence":"additional","affiliation":[{"name":"Faculty of Medical and Life Sciences, Sunway University, Jalan University","place":["Bandar Sunway, Selangor, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Du","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Nursing, and Education, MAHSA University","place":["Jenjarom, Selangor, Malaysia"]},{"name":"School of Nursing, Jiangsu Food & Pharmaceutical Science College","place":["Huai\u2019an, Jiangsu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoya","family":"Liu","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinjing","family":"Xiang","sequence":"additional","affiliation":[{"name":"The Second Affiliated Hospital of Chengdu Medical College, Nuclear Industry 416 Hospital","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1064","DOI":"10.3969\/j.issn.1672-1756.2019.07.022","article-title":"Research progress on dyadic coping.
