how do researchers calculate aggregate or composite scores for the AIHQ (ambiguous intention hostility questionnaire)

To understand how researchers calculate aggregate or composite scores for the Ambiguous Intentions Hostility Questionnaire (AIHQ), we need to explore the specific methodologies and scoring techniques involved in its implementation. The AIHQ is a psychometric tool designed to measure hostile social-cognitive biases, particularly in contexts related to paranoid thinking and social interpretations. Below, I provide a detailed overview of the scoring process.

Overview of the AIHQ

The AIHQ primarily assesses how individuals attribute intentions to ambiguous situations—often used in psychological evaluations related to paranoia and hostility. Researchers use various approaches to derive meaningful data from the responses.

Structure of the AIHQ

The AIHQ consists of several items where participants respond to scenarios that imply social interactions with ambiguous intentions. Typically, participants provide responses to items that can be categorized as follows:

• Self-report Questions: These questions directly gauge the participant's perceptions and biases regarding others' intentions.
• Open-Ended Questions: These require participants to articulate their thoughts about the ambiguous situations presented.

Scoring Methodology

Researchers primarily utilize two scoring systems when analyzing AIHQ responses:

1. Blame Index Calculation

This involves quantifying responses from self-report items. The aim is to create a “blame index” by summing the scores derived from three designated self-report questions. Each question is typically rated on a scale, and the total can indicate the level of hostility attributed by the respondent.

• Example Calculation:
  • Participant 1: Scores 2, 3, and 1 on the three questions.
  • Blame Index = 2 + 3 + 1 = 6.

2. Expert Rating of Open-Ended Responses

For the open-ended questions, researchers often employ independent judges to rate the responses on predetermined criteria, typically involving hostility or negativity in the participants' interpretations. Each response might be scored using a Likert scale (e.g., 1-5) that reflects the perceived hostility in the interpretation of the ambiguous intention expressed in the answer.

• Scores from these ratings may be averaged to contribute to the composite score of hostility attributed to others.

Composite Scores

Researchers may combine these two scoring methods to form an overall aggregate score that reflects the respondents' overall hostility bias. Here’s how this might look in practice:

• Total Composite Score = (Blame Index) + (Average Rating from Open-Ended Responses)

Considerations for Validity

To ensure the reliability and validity of the scoring process, researchers may also employ statistical analyses, including confirmatory factor analysis (CFA), to validate the constructs being measured. This process typically involves evaluating the factor structure of the questionnaire and ensuring that the scoring aligns with theoretical expectations.

Conclusion

The calculation of aggregate or composite scores for the AIHQ involves a blend of quantitative self-report metrics and qualitative assessments from open-ended responses. By summing self-reported blame indices and averaging expert ratings of open-ended responses, researchers can derive comprehensive scores that reflect the underlying hostile attribution bias. This methodological rigor is crucial for accurately interpreting social-cognitive biases, particularly in populations vulnerable to paranoia.
