Title: Examining the Efficacy of a Digitalized PECS Intervention on Social Communication in Children with Autism Spectrum Disorder

Introduction and Literature Review

Autism Spectrum Disorder (ASD) is characterized by deficits in social communication and interaction, alongside restricted and repetitive behaviors (American Psychiatric Association, 2013). Effective interventions aiming to improve social skills are critical for enhancing quality of life and integration for children with ASD (Locke et al., 2016). The Picture Exchange Communication System (PECS) has been recognized as an evidence-based intervention that facilitates functional communication in ASD children (Bondy & Frost, 1994). Recently, digital adaptations of PECS have emerged, leveraging technology to promote engagement and accessibility (Lemon et al., 2019). This study aims to evaluate whether a web-based PECS intervention enhances social motivation and communication skills in children with ASD, building upon previous empirical research indicating the potential of digital tools to augment traditional interventions (Tincani, 2014).

Existing literature demonstrates that PECS effectively increases communicative behavior; however, the transition to digital platforms warrants further investigation (Ganz & Simpson, 2007). Studies by Flippin et al. (2010) suggest digital interventions can improve motivation and spontaneous communication, but empirical evidence remains limited regarding their impact on social engagement. Furthermore, parental perceptions of digital tools' utility can influence adherence and outcomes (Field et al., 2011). This review underscores the necessity of a methodologically rigorous investigation into the efficacy and acceptability of web-based PECS programs specifically targeting social motivation in ASD children.

Research Question, Rationale, Aims, and Hypotheses

The primary research question probes whether the digitalized PECS intervention improves social motivation and communication skills among children with ASD. The rationale stems from the need to adapt evidence-based interventions for digital platforms to enhance accessibility and engagement. The study hypothesizes that children using the web-based PECS will demonstrate increased social motivation, as measured by observational metrics, and improved communication frequency compared to baseline measurements.

Research Methodology and Method

Design: A mixed-methods, within-subjects experimental design will be employed, combining quantitative measures of social motivation with qualitative parental feedback.

Participants: Forty children aged 3-6 diagnosed with ASD will be recruited via local clinics and support groups. Participants will be stratified by age and severity to ensure balanced groups.

Materials: The web-based PECS program developed by the research team, standardized observational assessment tools (e.g., Social Communication Questionnaire), and semi-structured parent interviews will be used.

Procedure: Participants will engage with the digital PECS for four weeks at home, with weekly therapist assessments. Data collection involves pre- and post-intervention measures of social motivation, communication frequency, and parental satisfaction.

Ethical considerations: Ethical approval will be obtained from the university ethics board. Informed consent will be secured from parents, with assurances of confidentiality and procedures to address any adverse effects.

Analysing and Reporting Findings

Quantitative data on social motivation and communication will be analyzed using paired t-tests to compare pre- and post-intervention scores. Effect sizes will be calculated to interpret clinical significance. Qualitative data from parental interviews will undergo thematic analysis to identify perceived benefits and barriers. Data visualization through bar graphs and line charts will illustrate changes over time. The combination of statistical and thematic analysis will provide a comprehensive understanding of intervention efficacy and acceptability.

Presentation & Referencing

The report will adhere to APA guidelines, ensuring proper citation and referencing of peer-reviewed sources such as related empirical studies on PECS, digital interventions, and ASD communication outcomes (Ganz & Simpson, 2004; Locke et al., 2017; Tincani, 2014; Lemon et al., 2019; Field et al., 2011). The document will be formatted with 12-point Arial font, double spacing, numbered pages, and 1-inch margins. Appendices will include detailed intervention protocols and assessment tools.
