The present study is the first to investigate the ACA+\u2019s content validity and factor structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>ACA+ and ACA-SF scores were obtained for 220 adolescents (50.9% boys), aged 12-18 years, living in residential out-of-home care (OOHC) in the UK. Item validity was estimated from item score distributions (item means and prevalence), and correlations with ACA+ total and ACA-SF scale scores. Factor structure was investigated using principal components factor analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      As anticipated, all item-rest correlations were positive (\n                      <jats:italic toggle=\"yes\">r<\/jats:italic>\n                      = .20 to .58), while correlations with the ACA-SF total score were all negative. However, items measuring emotion sharing and relational intimacy were positively correlated with several ACA-SF sub-scale scores, suggesting that among some adolescents these items measure maladaptive dysregulated emotion and relational difficulties. To maximise clinical utility, two sets of factor analyses were performed, yielding: a 21-item four-factor solution that can be safely interpreted by children\u2019s agencies; and a 29-item six-factor solution that requires skilled interpretation by mental health clinicians. Factor analyses explained 53.9% and 75.1% of the score variance respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The present analyses suggest the ACA+ has strong content and factorial validity for assessment of adolescents in residential OOHC.
