Traditionally, the magnitude of alpha is calculated by taking the average over a nomothetic fixed frequency window (e.g., 8 to 13\u2009Hz). Alternatively, methods have been proposed to extract individualized alpha frequency (IAF) peaks and windows in hopes of improving the reliability and validity of signal detection. However, no study has compared the nomothetic to IAF approaches to examine the reliability and validity of resting FAA in a large well\u2010characterized data set. In this study, we assessed the psychometric performance of the standard fixed window approach, a PZ\u2010alpha based IAF approach and a global\u2010alpha based IAF windows detection approach on a previously collected EEG data set (8 recordings per subject collected on four occasions across two weeks). Our results revealed that resting FAA calculated with these three different methods are highly correlated at all frontal regions (mean\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u00a0.98). The stability across the 8 recordings over the two weeks also showed no substantial difference between approaches as indicated by intraclass correlations. Moreover, internal\u2010consistency reliability, validity with respect to measures of emotion and emotion\u2010related psychopathology and state\u2013trait Structure equation model (SEM) fitting were evaluated and yielded no significant differences across methods. Our results supported the overall reliability and validity of two different IAF approaches to assessing resting FAA but fail to find any incremental advantage over nomothetic approaches to defining alpha bands. Guidelines for methods selection for future research are provided.\n                  <\/jats:p>","DOI":"10.1111\/psyp.14149","type":"journal-article","created":{"date-parts":[[2022,7,17]],"date-time":"2022-07-17T23:00:33Z","timestamp":1658098833000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A comparison of nomothetic and individualized alpha frequency approaches to measuring frontal\n                    <scp>EEG<\/scp>\n                    alpha asymmetry"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8878-8952","authenticated-orcid":false,"given":"Diheng","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Psychology University of Arizona  Tucson Arizona USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John J.
