Social Interaction Behavior Inventory (SIBI)

Abstract

The Social Interactions Behavior Inventory (SIBI) is a specialized psychological scale developed to assess the frequency and quality of social behaviors in children, particularly those diagnosed with High-Functioning Autism (HFA) or Asperger’s Syndrome. Developed by Winnie Wing Sum Chung in 2012, the SIBI utilizes a multi-informant approach, featuring both a Parent Version and a Child Version. The instrument is designed to capture social functioning across three primary ecological contexts: school, community, and home. Its comprehensive item structure examines crucial areas such as initiating play, maintaining friendships, conflict resolution skills, and engagement in organized activities, providing a detailed profile of the child’s real-world social engagement.

Purpose

The primary purpose of the Social Interactions Behavior Inventory (SIBI) is to offer a standardized, ecologically valid method for quantifying the social behaviors and interaction patterns of school-aged children, specifically targeting the unique social challenges faced by individuals with Autism Spectrum Disorder (ASD), particularly HFA or Asperger’s Syndrome.

Unlike measures focused solely on deficits, the SIBI aims to capture the frequency of both successful and challenging social engagements within a recent two-week period. This allows clinicians and researchers to monitor progress during interventions and accurately map the child’s functional social skills across diverse settings, including structured school environments and unstructured community settings.

Construct

The SIBI measures the overarching construct of Social Interactions, broken down into specific behavioral domains relevant to peer relations and family dynamics. The inventory operationalizes social functioning through several key sub-constructs, which include:

• Peer Engagement and Reciprocity: Items assessing initiation of play, participation in group games, and being chosen by peers.
• Friendship Maintenance: Items focused on establishing and maintaining specific friendships both inside and outside of school, including communication methods (e.g., calling or texting).
• Conflict and Bullying: Measures of experiencing teasing or bullying, as well as the ability to successfully resolve conflicts or arguments.
• Contextual Behavior: Specific assessment of social behavior across three distinct ecological domains: school/recess, community activities (e.g., clubs, sports), and interactions within the home environment.
• Preference and Motivation: Items capturing the child’s comfort level in social situations and expressed desire for more or better social interactions.

Validity

The psychometric investigation into the SIBI, detailed in the originating thesis, established foundational validity evidence. Content validity was ensured through the systematic development of items derived from clinical observations and literature reviews relevant to the social phenotype of High-Functioning Autism.

While specific statistical measures like convergent and discriminant validity require reference to the full academic document, the SIBI’s structure suggests strong ecological validity by segmenting behaviors based on real-world settings (school, community, home) and using dual perspectives (parent and child report), which is critical for measuring complex, contextual social constructs.

Reliability

Reliability analyses for the SIBI were conducted as part of its initial development, typically including measures of internal consistency (e.g., Cronbach’s alpha) for the overall scale and its respective subscales, as well as test-retest reliability to confirm stability over time.

The multi-informant structure inherently addresses reliability concerns by comparing the parent’s observation of the child’s behavior with the child’s own self-perception, offering a richer and more reliable assessment profile than a single-source inventory might provide. Specific reliability coefficients are documented in the complete thesis manuscript.

Factor Analysis

The SIBI was likely subjected to exploratory or confirmatory factor analysis during its development to determine the underlying dimensional structure of the scale and confirm that the items cluster into meaningful subscales that align with the theoretical constructs of social behavior (e.g., Peer Engagement, Solitary Play, Family Interaction).

The clear thematic grouping of items within the instrument (At School, In the Community, At Home) strongly suggests a multi-factorial structure designed to assess social functioning across these distinct environments. The results of the factor analysis are crucial for determining how scores should be aggregated and interpreted, and these details are contained within the original research document.

Instrument

Test Type: Behavioral Rating Scale; Multi-Informant (Parent Report and Child Self-Report)

Format: Paper-and-pencil questionnaire using modified Likert-type scales (ranging typically from “Not at all” to “Very often” or “A lot”) and dichotomous (Yes/No) questions, often referencing behavior within the previous two weeks.

Language Available: English (Original development language)

Population Group: Children with developmental differences, specifically those with Autism Spectrum Disorder (HFA/Asperger’s Syndrome).

Age Group: School-aged children (Specific age range determined by the developmental stage of the original thesis population, typically elementary to early middle school).

Population Details: Developed specifically for children whose primary challenge is social interaction rather than cognitive impairment, such as those historically classified as having High-Functioning Autism or Asperger’s Syndrome.

Test Methodology: Retrospective self-report (child) and observational report (parent) covering recent social activities and behaviors in various settings. The inventory includes open-ended questions to specify activities and friends’ names, adding qualitative depth.

Permissions & Fee and Test Year

The SIBI was developed in 2012 as part of a Master’s thesis at The Ohio State University.

Permissions: The instrument is available for academic review via the institutional repository of The Ohio State University. Researchers interested in using the SIBI should generally cite the original thesis and may need to contact the author or the university for commercial or large-scale clinical use, although academic use is often permitted upon citation.

Fee: Typically, instruments developed within academic theses are available for non-commercial research purposes without an associated fee.
