Psychological Treatment Symptom Data for Predicting Outcomes Using Latent Trait Scores

Data Sheet 1_Latent trait or sum score: addressing measurement challenges in the prediction of self-rated symptom outcomes in psychological treatment.csv is a 3.4 KB dataset shared by Nils Hentati Isacsson on figshare in March 2026. It contains self-rated symptom data from three questionnaires for 6,464 patients over the first 4 weeks of a 12-week psychological treatment program. The data is used to compare the predictive performance of traditional sum scores versus psychometrically optimized latent trait scores for post-treatment outcomes.

Use Cases

• Comparing predictive model performance (e.g., linear regression, random forest) based on latent trait scores versus traditional sum scores.
• Evaluating the impact of psychometric optimization (Rasch Measurement Theory) on prediction accuracy for symptom outcomes.
• Analyzing the relationship between early-treatment symptom data and post-treatment outcomes based on the described 4-week and 12-week timeframes.
• Investigating the effect of using a shorter questionnaire (23% of the full scale) on predictive performance in a clinical setting.

Strengths

• Data from a large cohort of 6,464 patients undergoing psychological treatment.
• Includes self-rated symptom data from three different questionnaires collected over a defined 4-week period.
• Dataset is licensed under CC-BY-4.0, permitting open sharing and adaptation.
• Analysis employed nested cross-validation and multiple imputations, suggesting a rigorous methodological approach.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small at 3.4 KB, indicating limited scope or a highly summarized format.
• Description metadata is limited; actual data structure and quality require manual inspection after download.
