Dataset: Longitudinal Effects of a Nurse-Led Self-Management Intervention on Quality of Life and Psychosocial Outcomes in Inflammatory Bowel Disease

This dataset supports a single-centre, longitudinal, repeated-measures study evaluating the psychosocial effects of a structured nurse-led psychoeducational intervention in adults with inflammatory bowel disease (IBD) in clinical remission. Sixty patients (38 with Crohn's disease, 22 with ulcerative colitis) were recruited from a tertiary IBD unit in Spain between September and December 2019 and followed over 12 months. Assessments were conducted at five time points: baseline prior to the intervention (V1), immediately post-intervention (V2), and at 3 (V3), 6 (V4), and 12 (V5) months.

The intervention consisted of four weekly 180-minute sessions coordinated by a specialist IBD nurse alongside a gastroenterologist and a clinical psychologist, covering pathology and disease management, coping strategies, intrapersonal emotional regulation, and interpersonal and relapse-prevention skills.

Instruments included:

CCVEII-9 – 9-item Short Quality of Life Questionnaire in Inflammatory Bowel Disease (scores 9–63; higher = better HRQoL)

PSS-14 – 14-item Perceived Stress Scale (scores 0–56; higher = greater stress)

HADS – Hospital Anxiety and Depression Scale (two 7-item subscales; scores 0–21 each; higher = worse)

Family APGAR – 5-item family functioning questionnaire (scores 0–10; higher = better functioning)

Dataset structure (4 sheets):

General Information: item-level questionnaire responses at baseline (n = 60; 54 variables)

Question-Variable Mapping: codebook linking variable codes to full questionnaire item text

Workshop: attendance records for each of the four psychoeducational sessions

Assessment V1–V5: coded responses across all five assessment time points (n = 263 observations; 49 variables)

The study protocol was approved by the Regional Clinical Research Ethics Committee of the Andalusian Public Health System (Seville, Spain; protocol code 2013PI/082) and conducted in accordance with the Declaration of Helsinki (2024 revision). Written informed consent was obtained from all participants. The study was designed and reported following the TREND statement for non-randomized intervention studies.
