Emotionality and Anxiety in Institutionalized Seniors: Pretest–Retest–Retest II Dataset

This dataset was created as part of a study investigating short‑term and long‑term affectivity and the dynamics of emotional change in seniors living in social care facilities. Data were collected across three measurement points (pretest, retest, and retest II) in two experimental groups and one control group. The aim of the study was to examine the effects of Snoezelen intervention and reminiscence therapy on emotionality and anxiety among institutionalized seniors. Each row in the dataset represents one respondent.Each column represents a specific measurement of a specific variable.
