Influence of item sequence on transient mood assessment

Area of Science:

• Psychological assessment
• Psychometrics
• Mood research

Background:

• Accurate transient mood assessment is crucial in psychological research.
• Standard mood scales often present items randomly, potentially affecting administration efficiency.
• Investigating alternative item sequencing for mood scales is warranted.

Purpose of the Study:

• To compare the psychometric validity of a standard mood scale presentation with an experimental version.
• To determine if grouping items by subscale affects mood assessment accuracy.
• To evaluate the time-effectiveness of an experimental mood scale for large groups.

Main Methods:

• Two groups of adults (N=300 and N=292) completed the Brunel Mood Scale.
• One group received the standard scale, while the other received an experimental version with items grouped by subscale.
• A distraction task was administered between scale presentations for one group.

Main Results:

• No significant differences in response patterns were observed between the standard and experimental mood scale presentations.
• Item sequencing according to mood subscales did not alter the accuracy of transient mood assessment.
• The experimental version demonstrated comparable psychometric validity to the standard version.

Conclusions:

• Grouping mood scale items by subscale is a valid method for transient mood assessment.
• The experimental version offers a time-effective scoring advantage for large-scale administration without compromising validity.
• Findings support the use of the experimental mood scale presentation in research settings.
