CFA findings were heterogeneous: 3 scales (nostrils, teeth, and jaws) met all predefined criteria; several scales showed partial fit; the Eating\/Drinking checklist showed consistently poor fit (root mean square error of approximation [RMSEA]\u2009=\u20090.123; standardized root mean square residual [SRMR]\u2009=\u20090.094). Clinically significant floor effects (\u226515%) were observed for nostrils and cleft lip scar; ceiling effects for speech distress, psychological function, school, and social function. Inter-scale correlations were broadly consistent with the conceptual structure of the instrument.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The Turkish CLEFT-Q demonstrated satisfactory internal consistency and good-to-excellent test\u2013retest reliability.
