Özet
Considering autism as a spectrum, dimensional measures such as the Adult Autism Subthreshold Spectrum (AdAS Spectrum) have been increasingly emphasized. The AdAS Spectrum is a self-report questionnaire designed to characterize autistic traits and subthreshold manifestations rather than establish an autism diagnosis. This study aimed to culturally adapt the AdAS Spectrum for the Turkish population and evaluate its validity and reliability. A total of 99 individuals with autism spectrum disorder and 348 typically developing participants were enrolled in the study. Participants completed the AdAS Spectrum, Autism Spectrum Quotient (AQ), and Empathy Quotient (EQ) scales. Confirmatory factor analysis supported the seven-domain structure of the original AdAS Spectrum (chi 2/df = 2.058, root mean square error of approximation [RMSEA] = 0.048, comparative fit index [CFI] = 0.952, Tucker-Lewis index [TLI] = 0.946, standardized root mean square residual [SRMR] = 0.038). The scale showed high internal consistency (Kuder-Richardson coefficient [KR-20] = 0.964), good-to-excellent test-retest reliability (intraclass correlation coefficient [ICC] = 0.800 through 0.961), and expected associations with another dimensional measure of autistic traits. These findings support the Turkish AdAS Spectrum as a self-report measure for the dimensional characterization of autistic traits in research. L'autisme & eacute;tant conceptualis & eacute; comme un spectre, les mesures dimensionnelles telles que l'& eacute;valuation du spectre autistique subclinique chez l'adulte (Adult Autism Subthreshold Spectrum; AdAS Spectrum) suscitent un int & eacute;r & ecirc;t scientifique croissant. L'AdAS Spectrum est un questionnaire d'auto-& eacute;valuation con & ccedil;u pour caract & eacute;riser les traits autistiques et les manifestations sous-cliniques plut & ocirc;t que pour & eacute;tablir un diagnostic d'autisme. Cette & eacute;tude visait & agrave; adapter culturellement l'AdAS Spectrum & agrave; la population turque et & agrave; en & eacute;valuer sa validit & eacute; et sa fiabilit & eacute;. Au total, 99 personnes pr & eacute;sentant un trouble du spectre de l'autisme et 348 participants au d & eacute;veloppement typique ont & eacute;t & eacute; recrut & eacute;s pour cette & eacute;tude. Les participants ont r & eacute;pondu & agrave; l'AdAS Spectrum, au Quotient du spectre de l'autisme (Autism Spectrum Quotient; AQ) et au Quotient d'empathie (Empathy Quotient; EQ). L'analyse factorielle confirmatoire a valid & eacute; la structure en sept domaines de l'AdAS Spectrum original (chi 2/df = 2,058 ; RMSEA = 0,048 ; CFI = 0,952 ; TLI = 0,946 ; SRMR = 0,038). L'& eacute;chelle a d & eacute;montr & eacute; une coh & eacute;rence interne & eacute;lev & eacute;e (KR-20 = 0.964), une fiabilit & eacute; test-retest allant de bonne & agrave; excellente (ICC = 0.800-0,961) et des associations attendues avec une autre mesure dimensionnelle des traits autistiques. Ces r & eacute;sultats valident la version turque de l'AdAS Spectrum comme un outil d'auto-& eacute;valuation permettant la caract & eacute;risation dimensionnelle des traits autistiques en contexte de recherche. Al considerar el autismo como un espectro, se ha puesto un & eacute;nfasis creciente en las medidas dimensionales, tales como la Escala del Espectro Subumbral de Autismo en Adultos (AdAS Spectrum). El AdAS Spectrum es un cuestionario de autoinforme dise & ntilde;ado para caracterizar los rasgos autistas y las manifestaciones subumbrales, m & aacute;s que para establecer un diagn & oacute;stico de autismo. Este estudio tuvo como objetivo adaptar culturalmente el AdAS Spectrum a la poblaci & oacute;n turca y evaluar su validez y fiabilidad. En el estudio participaron un total de 99 personas con trastorno del espectro autista y 348 participantes con desarrollo t & iacute;pico. Los participantes completaron las escalas AdAS Spectrum, Cociente del Espectro Autista (AQ) y Cociente de Empat & iacute;a (EQ). El an & aacute;lisis factorial confirmatorio respald & oacute; la estructura de siete dominios del AdAS Spectrum original (chi 2/gl = 2,058; RMSEA = 0,048; CFI = 0,952; TLI = 0,946; SRMR = 0,038). La escala mostr & oacute; una elevada consistencia interna (KR-20 = 0,964), una fiabilidad test-retest de buena a excelente (CCI = 0,800-0,961) y las asociaciones esperadas con otra medida dimensional de rasgos autistas. Estos hallazgos respaldan el uso del AdAS Spectrum en turco como medida de autoinforme para la caracterizaci & oacute;n dimensional de los rasgos autistas en el & aacute;mbito de la investigaci & oacute;n.
