Questionnaire-Based Implicit Association Test

The Questionnaire-based Implicit Association Test (qIAT) applies the widely-used Implicit Association Test to questionnaire items. Instead of one-word associations (e.g., Love/Hate > Self/Other), it utilizes items from validated questionnaires (e.g., "I start conversations" > True/False). Dr Iftah Yovel's Personality Cognition and Psychopathology Lab at The Hebrew University of Jerusalem continues to validate the qIAT with a range of individual difference constructs and is developing a program for other researchers to integrate the qIAT in their own research as well.

Validated constructs:

State Emotion Regulation Inventory (SERI) 

While there are many high-quality measures for how people tend to regulate their emotions in general (i.e., trait emotion regulation), there are far fewer validated measures for how people regulate their emotions in the moment (i.e., state emotion regulation). The SERI is a brief, validated measure of state emotion regulation that measures state use of distraction, reappraisal, brooding and acceptance.

Automated HLM Interaction Report Generator

Hierarchical LInear Modeling often requires lengthy, sophisticated programming, particularly when estimating interactions between Level 1 (i.e., individual) and Level 2 (i.e., group) variables. This publicly available R code automates such calculations.
