This systematic review aims to assess the methodological quality of cross\u2010sectional network analysis (NA) studies conducted on ED clinical populations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>PRISMA and PICOS criteria were used to retrieve NA studies on ED. Methodological quality was evaluated based on five criteria: variable\u2010selection procedure, network estimation method, stability checks, topological overlap checks, and handling of missing data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010three cross\u2010sectional NA studies were included. Most studies focused on populations that were female, white and, with an anorexia nervosa (AN) diagnosis. Depending on how many criteria were satisfied, 27.3% of studies (<jats:italic>n<\/jats:italic> =\u20099) were strictly adherent, 30.3% (<jats:italic>n<\/jats:italic> =\u200910) moderately adherent, 33.3% (<jats:italic>n<\/jats:italic> =\u200911) sufficiently adherent, and 9.1% (<jats:italic>n<\/jats:italic> =\u20093) poorly adherent. Missing topological overlap checks and not reporting missing data represented most unreported criteria, lacking, respectively, in 63.6% and 48.5% of studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Almost all reviewed cross\u2010sectional NA studies on ED report those methodological procedures (variable\u2010selection procedure, network estimation method, stability checks) necessary for a network study to provide reliable results. Nonetheless these minimum reporting data require further improvement. Moreover, elements closely related to the validity of an NA study (controls for topological overlap and management of missing data) are lacking in most studies. Recommendations to overcome such methodological weaknesses in future NA studies on ED are discussed together with the need to conduct NA studies with longitudinal design, to address diversity issues in study samples and heterogeneity of assessment tools.<\/jats:p><\/jats:sec><jats:sec><jats:title>Public Significance<\/jats:title><jats:p>The present work aims to evaluate the quality of ED NA studies to support applications of this approach in ED research. Results show that most studies adopted basic procedures to produce reliable results; however, other important procedures linked to NA study validity were mostly neglected. Network methodology in ED is extremely promising, but future studies should consistently include topological overlap control procedures and provide information on missing data.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23828","type":"journal-article","created":{"date-parts":[[2022,10,18]],"date-time":"2022-10-18T16:33:49Z","timestamp":1666110829000},"page":"1641-1669","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Network analysis studies in patients with eating disorders: A systematic review and methodological quality assessment"],"prefix":"10.1002","volume":"55","author":[{"given":"Giuliano","family":"Tomei","sequence":"first","affiliation":[{"name":"Department of Psychology University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Francesca","family":"Pieroni","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7178-1180","authenticated-orcid":false,"given":"Elena","family":"Tomba","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,10,18]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890423349"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphys2188"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13428-022-01839-y"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.4324\/9781003111238-9"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1159\/000495045"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/wps.20375"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s43586-021-00055-w"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/abn0000516"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1037\/met0000471"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23590"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23755"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23270"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.3390\/brainsci9100276"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/PSY.0b013e31820a1838"},{"key":"e_1_2_10_17_1","volume-title":"Systematic reviews: CRD's guidance for undertaking reviews in health care","author":"Centre for Reviews and Dissemination","year":"2006"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyt.2022.899757"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/per.2265"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jrp.2014.07.003"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.2832"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2017.2150"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2017.08.004"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1177\/2167702619865958"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13428-017-0862-1"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.1177\/2167702617744325"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.1177\/1745691612459059"},{"key":"e_1_2_10_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22871"},{"key":"e_1_2_10_29_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23070"},{"key":"e_1_2_10_30_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20455"},{"key":"e_1_2_10_31_1","doi-asserted-by":"publisher","DOI":"10.1177\/1745691617705892"},{"key":"e_1_2_10_32_1","doi-asserted-by":"publisher","DOI":"10.1093\/biostatistics\/kxm045"},{"key":"e_1_2_10_33_1","doi-asserted-by":"publisher","DOI":"10.1037\/abn0000327"},{"key":"e_1_2_10_34_1","doi-asserted-by":"publisher","DOI":"10.1017\/s0033291721001604"},{"key":"e_1_2_10_35_1","doi-asserted-by":"publisher","DOI":"10.1080\/00273171.2019.1677207"},{"key":"e_1_2_10_36_1","doi-asserted-by":"publisher","DOI":"10.1080\/21642850.2018.1521283"},{"key":"e_1_2_10_37_1","doi-asserted-by":"publisher","DOI":"10.1159\/000509458"},{"key":"e_1_2_10_38_1","unstructured":"Jones P.
