Early Play Behaviors of Infants at Elevated Likelihood for Autism Spectrum Disorder.

IMPORTANCE: Although research has examined early identification of autism spectrum disorder (ASD), few studies have found behavioral markers during midinfancy associated with later ASD diagnosis. OBJECTIVE: To examine infants' play behaviors and atypical positions at age 6 mo and later outcome classification among infants at elevated likelihood (EL) and typical likelihood (TL) for ASD. Atypical positions refer to movement patterns indicative of motor delays or deviations, including atypical extension and flexion, poor weight shift and rotation, hypertonicity or hypotonicity, and the presence of primitive reflex patterns. DESIGN: Observational cohort longitudinal design using blinded video analysis. PARTICIPANTS: Fifty-eight infants (41 EL infants and 17 TL infants) 6 mo of age. RESULTS: Infants later diagnosed with ASD needed more support to engage in play at age 6 mo compared with infants who did not receive an ASD diagnosis (U = 130, z = -2.29, p < .05, r = .31). Atypical positions at 6 mo of age were not associated with a later diagnosis of ASD. CONCLUSIONS AND RELEVANCE: Play behaviors may be early indicators of developmental differences for infants later diagnosed with ASD. The results of this pilot study suggest the need to observe the quality of interaction with a caregiver and objects during early play, which may serve as potential early indicators of ASD. Plain-Language Summary: Few studies have found behavioral markers during midinfancy that are associated with a later diagnosis of autism spectrum disorder (ASD). The results of this study showed that infants who were later diagnosed with ASD were found to have differences in play behaviors compared to infants who were not later diagnosed with ASD. Thus, early play behaviors may be an early indicator of developmental differences for infants who are later diagnosed with ASD.

Guidelines for supervision, roles, and responsibilities during the delivery of occupational therapy services.

These guidelines about supervision, roles, and responsibilities are to assist in the appropriate utilization of occupational therapists, occupational therapy assistants, and occupational therapy aides and in the appropriate and effective provision of occupational therapy services. It is expected that occupational therapy services are delivered in accordance with applicable state and federal regulations, relevant workplace policies, the Occupational Therapy Code of Ethics (AOTA, 2005), and continuing competency and professional development guidelines.

Guidelines for supervision, roles, and responsibilities during the delivery of occupational therapy services (2004).

These guidelines about supervision, roles, and responsibilities are to assist in the appropriate utilization of occupational therapy personnel and in the appropriate and effective provision of occupational therapy services. All personnel are expected to meet applicable state and federal regulations, adhere to relevant workplace policies and the Occupational Therapy Code of Ethics (AOTA, 2000), and participate in ongoing professional development activities to maintain continuing competency.
