perspectives : client, parents, school and other professionals in order to get to know a child’s profile : ability, strengths and needs , in order to provide suitable and appropriate interventions
• Evaluation :Clinical & Formal • Assessment: Diagnostic & Follow up– Developmental & Behavioral– Psychoeducational– Neurodevelopmental / Neuropsychological – Speech& Language – Physio/Occupational
Case Vignette: JK 5-yr boy
• Clinical assessment: parent clinical interview, play-based developmental evaluation /MSE
• Diagnostic evaluation:ADI-R, ADOS,Mullen Scales, NEPSY-II (AT/EF, SP:ToM,AR)School vdo, school visitQuestionnaires: SDQ, SNAP-IV,PDDSQ
Case Vignette: JK 5-yr boy
• Assessment results• Clinical Diagnosis based on
DSM-IV TR (2000) &DSM-5 (2013)
• Recommendations : Ix, Rx, F/U
• Feedback / Collaborations

So, Does Diagnosis Matter?Why?
• Universal Language among professionals• Practice Guidelines/Road map: for
Intervention , Counseling, Prognosis• Strengths & Needs• Future Research : etiology , specific treatment, course, prognosis
