Cognitive Assessment Questionnaire Dataset
Description
This dataset contains anonymized participant responses collected using a 25-item Cognitive Assessment Questionnaire designed to assess the frequency of everyday cognitive failures. The questionnaire evaluates common minor mistakes and failures involving memory, attention, perception, and everyday actions. Participants reported how frequently they experienced each situation during the previous six months using a five-point response scale ranging from 0 (Never) to 4 (Very often). The dataset was collected through an online Google Forms questionnaire and subsequently exported to Microsoft Excel for data organization, cleaning, and processing. The final dataset contains 1,399 participant records and includes the questionnaire responses along with selected demographic variables. For each participant, responses to the 25 questionnaire items are provided in numerical form. The questionnaire documentation specifies that the individual item scores can be summed to obtain an overall cognitive failures score ranging from 0 to 100. The dataset also includes processed categorical information corresponding to three dimensions described in the questionnaire documentation: Forgetfulness, Distractibility, and False Triggering. These dimensions represent different aspects of everyday cognitive failures, including difficulties in remembering information or intentions, maintaining focused attention, and interruptions in sequences of cognitive or motor actions. The repository package includes anonymized questionnaire responses in CSV and Excel formats, a processed dataset, a data dictionary, and documentation describing the dataset structure, response coding, scoring, and reproducibility procedure. This dataset is intended to support research and analysis in cognitive assessment, behavioral research, psychology, cognitive science, data analytics, and machine-learning-based classification of cognitive assessment responses. The anonymized data can be used for statistical analysis, exploratory research, predictive modeling, classification, and reproducibility studies. Direct identifying information has been excluded from the publication dataset. Researchers intending to reuse the data should consider the applicable ethical, consent, privacy, and institutional requirements before secondary use.

Steps to reproduce
1. Questionnaire preparation A 25-item Cognitive Assessment Questionnaire was designed and administered to collect information about the frequency of everyday cognitive failures. Each item uses a five-point response scale ranging from 0 (Never) to 4 (Very often). The questionnaire document describes the assessment as measuring everyday slips and errors involving perception, memory, and motor functioning. 2. Online data collection The questionnaire was implemented using Google Forms and distributed to participants through an online survey. Participant responses were automatically recorded in the associated response spreadsheet. 3. Response data export The collected responses were exported from the Google Forms response sheet into Microsoft Excel format for data organization and further processing. 4. Data cleaning and preparation The collected response data were reviewed and organized. Direct identifying information and unnecessary fields were excluded from the public dataset to produce an anonymized version suitable for data sharing. 5. Questionnaire response coding Responses to the 25 questionnaire items were represented using the numerical scale: 0 = Never 1 = Very rarely 2 = Occasionally 3 = Quite often 4 = Very often 6. **Cognitive assessment scoring** The questionnaire documentation specifies that the ratings of the 25 individual items can be summed to obtain an overall score ranging from **0 to 100**. 7. **Subscale processing** The processed dataset contains categorical outputs associated with the three dimensions described in the questionnaire documentation: **Forgetfulness, Distractibility, and False Triggering**. The documented item groupings are used to represent these dimensions. 8. **Dataset organization** The final dataset was organized into: * anonymized participant responses; * processed/filtered data; * a data dictionary describing variables and coding; and * a README file containing dataset documentation. 9. **Reproducibility** Researchers can reproduce the dataset preparation by using the questionnaire, collecting responses through the online form, exporting the response spreadsheet, applying the same data-cleaning and anonymization procedure, coding the 25 questionnaire responses on the 0–4 scale, and applying the documented scoring/subscale procedure. 10. **Data sharing** The resulting anonymized files are provided in CSV and Excel formats to facilitate reuse, analysis, and reproducibility. The original questionnaire is provided as supporting documentation for interpretation of the variables and scoring procedure.
