Background: The environmental enrichment (EE) framework has inspired several early intervention (EI) approaches. This study evaluated the feasibility, safety, caregiver acceptance, and satisfaction of implementing the HEP Approach intervention, a novel EI model based on the EE paradigm. Outcome measures for motor development, individual functional goals, sensory functions, caregiver-provided environmental affordances, and motivation for movement were examined. Methods: A pre-post-study design examined 18 premature infants (<33 weeks six days gestation) with a corrected age of 4–10 months. A 21-item Likert scale survey assessed the feasibility, safety, acceptability, and satisfaction of implementing the HEP Approach intervention. The Peabody Developmental Motor Scales-2, Test of Sensory Functions in Infants, Affordances in the Home Environment for Motor Development, and Infant Movement Motivation Questionnaire were used for outcomes. The goal attainment scale measured progress toward parent goals. The HEP Approach consisted of 12 one-hour sessions implemented over three months. Results: Most participating parents found the HEP Approach intervention feasible, safe, acceptable, and satisfactory. GAS scores demonstrated significant gains with a mean t-score of 67.75 (SD = 2.00). Results found significant improvement (p ≤ 0.05) in all outcome measures. Conclusions: Results suggest that the HEP Approach intervention is safe, feasible, and acceptable to implement. Outcome measures were meaningful and sensitive in identifying improved motor development, individualized parental goals, sensory functions, caregivers’ use of environmental opportunities, and movement motivation in premature at-risk infants. Results suggest further studies on the HEP Approach are feasible, and highlight the potential of this intervention to inspire and guide future research in this field.

The Evaluation in Ayres Sensory Integration (EASI) is a performance-based assessment tool designed to evaluate sensory reactivity, sensory perception, postural-ocular control, bilateral integration, and praxis abilities in children aged 3 to 12 years. There is no standardized performance assessment to evaluate sensory integration functions with Turkish children. The objective of this study is to develop a translated and culturally adapted Turkish version of the EASI for use in clinical practice and research. A seven-step process for translation and cross-cultural adaptation was implemented based on current recommendations identified in the litterature. The process includes forward and backward translations, expert syntesis, linguistic review, cognitive interviews, and pilot testing. The seven-step procedure for translating and culturally adapting the EASI resulted in a Turkish version of the 20 subtests of the EASI. Although revisions were required in the synthesis and linguistic analysis phase, there were no semantic or conceptual inconsistencies in the forward translations. Some discrepancies between the backward translation and the original form were identified and resolved; none of the discrpencies were directly linked to the administration or scoring of the tests. A Turkish version of the EASI has been developed through a research-guided seven-step method, incorporating translation and cultural adaptation. The Turkish translation and cultural adaptation of the EASI will support evidence based practice and research in the field of sensory integration within the Turkish population.
