Description

The Subject Impressions Questionnaire (SIQ) is a tool designed to assess participants’ impressions and reactions regarding a specific experience, event, or intervention. The SIQ is commonly used in research settings to capture the subjective experience of participants and to understand how they perceive and respond to different stimuli or situations.

Purpose

The main goal of the SIQ is to provide both a quantitative and qualitative evaluation of participants’ impressions. Specifically, the SIQ aims to measure:
Emotional Reactions: How participants feel about their experience.
Cognitive Impressions: How participants perceive and evaluate the experience.
Behavioral Intentions: How participants intend to act or respond after the experience.
Overall Satisfaction: The level of satisfaction participants derive from the experience.

Analysis

The analysis of data collected through the SIQ includes various statistical and qualitative methods to ensure the tool’s reliability and validity:
Factor Analysis: Used to examine the internal structure of the SIQ and confirm that the questions are appropriately grouped into corresponding dimensions.
Reliability: Assessed through the internal consistency of SIQ subscales, usually using Cronbach’s alpha.
Validity: Checked by correlating SIQ results with other validated measures of impressions and reactions, ensuring the tool measures what it is intended to.
Qualitative Analysis: Open-ended responses can be analyzed thematically to uncover common patterns and themes in participants’ subjective impressions.

Scoring

Scoring for the SIQ includes the following steps:
Data Collection from Representative Samples: Data is gathered from diverse participant samples to ensure generalizability of results.
Distribution Analysis: Score distributions are examined to confirm they are normally distributed and representative of participants’ impressions.
Establishing Normative Values: Norms and percentiles are developed to interpret results, enabling comparison across different participant groups and situations.
