*4.2. User Instructions TEA-CIFunciona*

To facilitate adoption and implementation of TEA-CIFunciona in clinical practice, we propose simple user instructions (Figure 3). Briefly, (1) to apply TEA-CIFunciona children and youth have to have a confirmed diagnosis of ASD, using validated diagnostic tools; (2) a multi-disciplinary team with active collaboration with parents and/or caregivers and children with ASD—when possible should participate in the assessment process, a proposed toolbox of items is suggested to address each ICF category contained in TEA-CIFunciona version 1.0; then (3) build a profile of functioning to summarize the findings of the assessment and highlights functional strengths and needs, along with environmental barriers and facilitators; finally (4) develop a functional comprehensive collaborative plan of intervention.
