the Information Systems Trust–Measurement Model

Description

The Information Systems Trust–Measurement Model (Müller & Hertel, 2025) explores the influence of trusting information systems in routine work events on cognitive resources, performance, and well-being. The instrument was developed for a study involving a German sample of employed users of information systems. The constructs were assessed using 37 items adapted from prior research (e.g., Cacioppo et al., 1996; de Rijk et al., 1998). The authors reported factor analysis, reliability, and validity results for these items.

Purpose

The measurement model aims to assess event-specific trust in information systems, work outcomes, and context conditions.

Validity

For convergent validity, the average variance extracted (AVE) was calculated. The AVE exceeded the recommended threshold of 0.50 for each scale, except for the need for control scale (AVE=0.47).
For discriminant validity, results indicated that all heterotrait-monotrait ratio (HTMT) values were below the recommended threshold of 0.85.
Test Methodology:
The test validity was assessed using convergent validity and discriminant validity methods.

Reliability

Internal consistency was assessed by computing Cronbach’s alpha (for scales with three items or more) or Spearman-Brown correlations (for two-item scales). The values ranged from .55 to .93.
Test Methodology:
The test reliability was assessed using internal consistency.

Factor Analysis

Confirmatory factor analysis was conducted to evaluate the goodness of fit of the saturated model using the standardized least square residuals (SRMR), unweighted least squares discrepancy (dULS), and geodesic discrepancy (dG). The SRMR value was 0.075, which is below the recommended threshold of 0.080 (Hu, Bentler, & Kano, 1992). Both discrepancy indicators were below their corresponding 95% quantile reference distribution, providing empirical support for the latent variables.
Test Methodology:
The factor analysis was assessed using confirmatory factor analysis.

Test Methodology

Test Methodology:
The measurement model was examined for test validity, convergent validity, discriminant validity, test reliability, internal consistency, and factor analysis.
