Assessment of Computer Task Performance (ACTP): The Arabic Version

Research output: Contribution to journalArticle


The aim of this study was to assess the inter-rater reliability of the Arabic version of the
Assessment of Computer Task Performance (ACTP) when used for children with Intellectual
and Developmental Disabilities (IDD), and to determine its internal consistency and sensitivity
to differences in gender and type of disability. A stratified convenience sample of 30 boys and
girls, native speakers of Arabic, who ranged in age from 6 to 21 years and had moderate IDD
participated in the study. The ACTP was used to assess the participants’ performance while performing standard computer tasks, and was rated by two expert occupational therapists in order to evaluate its inter-rater reliability. Five out of twelve standardized timed tasks from the ACTP were measured. The sample in the current study performed slower than typically developing children and youth, and slower than participants with motor impairments, examined in previous studies. Differences were found in performance time between girls and boys, and between three diagnostic subgroups. Internal consistency between the 31 ACTP tasks was high (a=0.934). Inter-rater reliability between the scores of the two occupational therapists (Rs ranged between 0.665- 0.99). This study confirmed that the Arabic version of the ACTP-Child version is a reliable and valid assessment when used to examine the ability of children and youth with IDD to use adapted computer pointing devices (mouse).
