The purpose of this study was to examine the psychometric properties of a new rating scale, the Limited Prosocial Emotions Questionnaire (LPEQ). Caregivers ( n = 1,050) of children ( M\n                    <jats:sub>age<\/jats:sub>\n                    = 8.42, SD = 2.31) completed the LPEQ and other measures. Results provide support for a single factor model of the LPEQ, with measurement invariance supported across child and informant sex. Both the reliability and validity of the LPEQ as a measure of LPEs were also well supported. Children identified with LPE had significantly greater average impairment and need for treatment relative to children without LPE. Children with conduct problems (i.e., conduct disorder or oppositional defiant disorder), as well those without conduct problems, had significantly more impairment if they were identified as having LPE. Our findings fit with the mounting evidence of the clinical utility of assessing LPEs in children. Future research should look to replicate our findings in clinical samples of youth.\n                  <\/jats:p>","DOI":"10.1177\/1073191120927782","type":"journal-article","created":{"date-parts":[[2020,6,4]],"date-time":"2020-06-04T05:09:22Z","timestamp":1591247362000},"page":"1882-1896","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Initial Investigation of the Psychometric Properties of the Limited Prosocial Emotions Questionnaire (LPEQ)"],"prefix":"10.1177","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4137-7096","authenticated-orcid":false,"given":"Peter J.","family":"Castagna","sequence":"first","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dara E.","family":"Babinski","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanda M.","family":"Pearl","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James G.","family":"Waxmonsky","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel A.","family":"Waschbusch","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,4]]},"reference":[{"key":"bibr1-1073191120927782","doi-asserted-by":"crossref","unstructured":"Achenbach T.
