Aim: To explore direct and indirect actor and partner effects among parents\u2019 instrumental family support, diet quality, and satisfaction with food-related life (SWFoL) in dual-earner families with adolescents. Methods: Online surveys were conducted with 860 dual-earner parent dyads and one adolescent child (mean age 12.7 \u00b1 1.8 years; 49.8% female) in Chile. Family members completed the Adapted Healthy Eating Index and the SWFoL Scale; parents also answered an Instrumental Support subscale. Analyses were conducted using a mediation Actor\u2013Partner Interdependence Model via structural equation modeling. Results: Mothers\u2019 and fathers\u2019 instrumental support was positively associated with their own SWFoL, both directly and indirectly via their diet quality. Parents\u2019 support was also positively related to adolescents\u2019 SWFoL directly and indirectly via adolescents\u2019 diet quality. Symmetrical crossover effects between instrumental support and SWFoL emerged for both parents. Mothers\u2019 support was additionally associated with fathers\u2019 SWFoL indirectly through fathers\u2019 diet quality. Conclusions: Instrumental support operates as a vital systemic resource within dual-earner households. By enhancing diet quality, tangible support protects family food-related well-being and embeds adolescents\u2019 nutritional health within the parental resource ecosystem.<\/jats:p>","DOI":"10.3390\/nu18162646","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T08:06:16Z","timestamp":1786608376000},"page":"2646","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Parents\u2019 Instrumental Family Support, Diet Quality, and Satisfaction with Food-Related Life: A Dyadic Approach in Dual-Earner Parents and Their Adolescent Children"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4438-3379","authenticated-orcid":false,"given":"Berta","family":"Schnettler","sequence":"first","affiliation":[{"name":"Facultad de Ciencias Agropecuarias y Medioambiente, Universidad de La Frontera, Temuco 4811230, Chile"},{"name":"Centro de Excelencia en Psicolog\u00eda Econ\u00f3mica y del Consumo, Universidad de La Frontera, Temuco 4811230, Chile"},{"name":"Scientific and Technological Bioresource Nucleus (BIOREN-UFRO), Universidad de La Frontera, Temuco 4811230, Chile"},{"name":"Facultad de Econom\u00eda y Empresa, Universidad Cat\u00f3lica de Santiago de Guayaquil, Guayaquil 090150, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9374-7095","authenticated-orcid":false,"given":"Andr\u00e9s","family":"Concha-Salgado","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda, Universidad de La Frontera, Temuco 4811230, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2575-3047","authenticated-orcid":false,"given":"Ligia","family":"Orellana-Calder\u00f3n","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Psicolog\u00eda Econ\u00f3mica y del Consumo, Universidad de La Frontera, Temuco 4811230, Chile"},{"name":"Departamento de Psicolog\u00eda, Universidad de La Frontera, Temuco 4811230, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9673-5727","authenticated-orcid":false,"given":"Mahia","family":"Saracostti","sequence":"additional","affiliation":[{"name":"Departamento de Trabajo Social, Universidad de Chile, Santiago 8330014, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2664-1386","authenticated-orcid":false,"given":"Katherine","family":"Bero\u00edza","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Psicolog\u00eda Econ\u00f3mica y del Consumo, Universidad de La Frontera, Temuco 4811230, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5267-6086","authenticated-orcid":false,"given":"H\u00e9ctor","family":"Poblete","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Psicolog\u00eda Econ\u00f3mica y del Consumo, Universidad de La Frontera, Temuco 4811230, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6154-5141","authenticated-orcid":false,"given":"Leonor","family":"Riquelme-Segura","sequence":"additional","affiliation":[{"name":"Departamento de Trabajo Social, Universidad de La Frontera, Temuco 4811230, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6155-4870","authenticated-orcid":false,"given":"Germ\u00e1n","family":"Lobos","sequence":"additional","affiliation":[{"name":"Facultad de Econom\u00eda y Negocios, Universidad de Talca, Talca 3460000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1466-6420","authenticated-orcid":false,"given":"Cristian","family":"Adasme-Berr\u00edos","sequence":"additional","affiliation":[{"name":"Departamento de Econom\u00eda y Administraci\u00f3n, Universidad Cat\u00f3lica del Maule, Talca 3466132, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1509-7242","authenticated-orcid":false,"given":"Mar\u00eda","family":"Lapo","sequence":"additional","affiliation":[{"name":"Facultad de Econom\u00eda y Empresa, Universidad Cat\u00f3lica de Santiago de Guayaquil, Guayaquil 090150, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"162","DOI":"10.1037\/str0000288","article-title":"Do work stressors relate to social support provision?
