Evaluating the Effectiveness of the Picture Exchange Communication System (PECS) for Enhancing Communication Skills in Children with Autism: Perspective of Speech Therapists in Lahore, Pakistan

Abstract

This study examined the effectiveness of the Picture Exchange Communication System (PECS) in enhancing communication skills among children with Autism Spectrum Disorder (ASD) from the perspectives of speech therapists in Lahore, Pakistan. A mixed-methods descriptive research design was employed, involving 53 speech therapists working in clinical, school, and home-based settings. Quantitative data were collected through a structured questionnaire and analyzed using descriptive statistics to assess perceived effectiveness, communication outcomes, and the relationship between duration of PECS use and communication improvement. Qualitative data from open-ended responses were analyzed thematically to explore factors influencing PECS implementation and effectiveness. Findings revealed that PECS was perceived as highly effective in improving expressive and receptive language, promoting social interaction, and reducing challenging behaviors, with greater improvements associated with longer and consistent use across settings. Qualitative insights highlighted the importance of professional training, parental involvement, and consistency in implementation. Ethical principles were strictly observed, including informed consent, confidentiality, and voluntary participation. The study underscores the value of PECS as an effective communication intervention while emphasizing the need for systemic support to maximize its impact in Pakistan
