Introduction and aims: Childhood apraxia of speech (CAS) is a speech sound disorder (SSD) lacking a quantifiable measure discriminating all cases of CAS from other SSDs. This project aimed at exploring CAS using different perspectives when examining speech and language difficulties commonly seen in 5-year-old children with suspected CAS or children with repaired cleft palate (CP±L). Children with CP±L were added to broaden and differentiate the knowledge base on CAS and to search for factors explaining unfavorable speech outcome in this group.Material and methods: In study I, a questionnaire was constructed and used, anonymously surveying Swedish SLPs (n=178) knowledge and praxis about CAS features and assessment. Findings were compared to earlier survey findings from English contexts. Study II examined articulation proficiency and orofacial function of children with CP±L (n=52) based on SLP examination and parental interview. For measurement of intelligibility, both parent reports and SLP ratings were compared. Study III included children with CP±L and disordered speech (n=19) and children with suspected CAS (n=15). Phonetic transcription and CAS diagnostics were based on audio-recordings of single word naming. The diagnosis was built on judgement of presence or absence of speech features using a checklist constructed for English speakers. The cross-linguistic applicability of the operationalized features and checklist was tested. In study IV language competence of children with CAS and CP±L was directly assessed, and parental ratings of everyday life communication were added, and results compared.Results: Swedish SLP's views on typical speech characteristic of CAS, surveyed in study I, corresponded in large with reports of SLP's from English-speaking contexts. The top seven characteristics were inconsistent speech production, sequencing difficulties, oro-motor deficits, vowel errors, voicing errors, consonant cluster deletion and prosodic disturbance. In study II, 37% of children with CP±L were found to have orofacial dysfunction; however, this was not an explanatory factor for speech outcome for these children. A distinct CAS profile, found in study III, included the five features: phonemic speech inconsistency for consonants and vowels plus vowel error, voicing error, difficulty achieving initial articulatory configurations or transitionary movement gestures and stress errors. In study IV, expressive language disorder was found in 67% of children with CAS. Receptive language ability was significantly better than expressive language in all children with CAS. No such difference was observed in the group of children without CAS (non-CAS SSD). Parent ratings of communication skills reflected an increased burden on communication in everyday life when difficulties within both speech and language domains were present.Conclusions: Despite relevant theoretical and/or clinical knowledge about CAS, Swedish SLPs reported a need for further education. Swedish-speaking 5-year-olds with CAS shared a distinct speech profile including five features, with prosodic impairment almost exclusively seen in children with CAS. Findings supported cross-linguistic applicability of CAS speech feature operationalization between English and Swedish speakers. In children with CP±L and SSD, a heightened cooccurrence of CAS, compared to clinical prevalence, should be anticipated. Expressive language ability in children with CAS was worse than receptive language ability.

520 $a Introduktion och syfte: Taldyspraxi (TD) ar en talstorning som ar svar att diagnostisera eftersom det saknas ett kvantifierbart matt som sarskiljer alla barn med TD fran barn med andra typer av talstorningar. Syftet med detta projekt var att utforska tal- och sprakformagan hos 5-aringar med TD och hos barn med gomspalt. Barnen med gomspalt inkluderades for att bredda och nyansera kunskapen om TD men ocksa for att soka efter faktorer som kan forklara kvarstaende talstorning hos en andel 5-aringar behandlade for gomspalt. Material och metoder: I studie I utvecklades en enkat med fragor kring kunskap och praxis gallande sardrag och undersokning av TD som besvarades anonymt av svenska barnlogopeder (n=178). Svaren jamfordes med tidigare enkatstudiesvar av logopeder i engelsksprakiga kontexter. I studie II undersoktes tal och orofacial funktion hos 52 barn med gomspalt, direkt av logoped och indirekt genom fragor till barnets foraldrar, talforstaelighet skattades av bade logoped och foraldrar och skattningarna jamfordes. I studie III deltog 19 barn med gomspalt och talstorning samt 15 barn med formodad TD. Talet spelades in vid bildbenamning samt transkriberades. TD-diagnosen byggde pa logopedbedomning av olika sardrag i talet, utifran en checklista utformad for engelsksprakiga barn. Checklistan och validiteten i beskrivningen av sardragen undersoktes avseende anvandning pa svenska. I studie IV undersokte logoped den sprakliga formagan hos barn med TD eller gomspalt och kommunikationsformagan i det dagliga livet skattades av foraldrarna, varefter resultaten jamfordes. Resultat: Svenska logopeders kunskap om typiska sardrag i talet hos barn med TD, som undersoktes i studie I, overensstamde i stort med engelsksprakiga logopeders. De sju mest frekvent rapporterade dragen var inkonsekvent tal, svarigheter med sekvensering av talljud, oralmotoriska svarigheter, vokalfel, svarigheter med distinktionen tonande-tonlos, forenklingar av konsonantkluster samt avvikande prosodi. I studie II uppvisade 37 % av barnen med gomspalt en orofacial dysfunktion, som dock inte forklarade barnens talstorning. I studie III framkom en sarskild TD-profil med fem sardrag: inkonsekvent uttal av konsonanter och vokaler samt vokalfel, svarigheter med distinktionen tonandetonlos, svarigheter att hitta artikulatorisk rorelse for ordstart och koartikulation mellan sprakljud samt avvikande prosodi. Expressiv sprakstorning konstaterades hos 67 % av barnen med TD i studie IV. Sprakprofilen, med en signifikant battre receptiv an expressiv formaga, sags enbart hos barn med TD. Foraldraskattningen av kommunikationsformagan i det dagliga livet pekade pa storre svarigheter for barn med bade tal- och sprakstorning. Slutsatser: Trots relevant teoretisk/klinisk kunskap om TD uppgav de flesta svenska barnlogopeder ett utbildningsbehov. En specifik talprofil hos svensktalande femaringar med TD framkom. Talprofilen bestod av fem talkarakteristika och inkluderade prosodiska svarigheter noterades i princip uteslutande hos barn med TD. Resultaten stodjer anvandningen av beskrivna och operationaliserade talkaraktaristika for engelsktalande barn ocksa for svensktalande barn. Hos barn med gomspalt och talstorning borde en hogre andel barn forvantas ha TD, jamfort med kliniska prevalensuppgifter. Expressiv sprakformaga hos barn med TD var generellt samre an receptiv formaga. Avvikande artikulationsformaga hos barn med gomspalt forklarades inte av orofacial dysfunktion. Foraldraskattningar av vardaglig kommunikationsformaga visade att det fanns storre svarigheter hos barn med bade tal- och sprakstorning. Dessa foraldraskattningar tillforde information om kommunikationsformagan i det dagliga livet och starkte den ekologiska validiteten hos de kliniska bedomningsmetoderna for TD.
