Detailed Description
This study was conducted with individuals who agreed to participate voluntarily. Face-to-face
interviews were carried out under pandemic precautions, participants were informed about the
study, and written informed consent was obtained.
Control Group
Participants in the control group completed baseline assessments including the Sociodemographic
Characteristics Form, BBÜRDÖ, and the Pressure Injury Knowledge Test for Wheelchair Users via
online forms administered simultaneously with telephone interviews. For participants with existing
pressure injuries, home visits were conducted under pandemic precautions, and the Pressure Ulcer
Scale for Healing (PUSH) was applied during baseline, follow-up, and post-test assessments.
After completion of the intervention group’s training sessions, the control group was followed
weekly for 12 weeks. During follow-up, the BBÜRDÖ and Pressure Injury Follow-up Form were
administered via telephone interviews. No preventive pressure injury interventions were applied to
the control group to avoid influencing knowledge outcomes. Routine counseling was not provided;
participants were referred to healthcare services only upon request.
At the end of the 12-week follow-up period, post-test assessments were conducted using the
BBÜRDÖ, Pressure Injury Knowledge Test for Wheelchair Users, and Pressure Injury Follow-up
Form. Home visits were performed for participants with existing or newly developed pressure
injuries, and the PUSH scale was applied. After completion of post-tests, educational sessions were
offered to the control group.
Intervention Group
Baseline assessments in the intervention group included the Sociodemographic Characteristics
Form, BBÜRDÖ, Pressure Injury Knowledge Test for Wheelchair Users, and Pressure Injury
Follow-up Form, administered online with concurrent telephone interviews. Home visits were
conducted for participants with existing pressure injuries, and the PUSH scale was applied.
Participants attended structured educational sessions delivered online via Zoom. Four training
groups (9–10 participants per group) completed three interactive sessions over two weeks. Each
session lasted 60 minutes and covered pressure injury definition, etiology, risk factors, prevention
strategies, and care practices. Educational materials were shared prior to the sessions, and a
WhatsApp group was created to facilitate communication and interaction.
Following the training sessions, participants received weekly follow-up for 12 weeks with
individualized counseling based on their needs. During follow-up, the BBÜRDÖ and Pressure Injury
Follow-up Form were administered via telephone interviews. Participants who implemented at least
one pressure injury prevention intervention were considered compliant. Home visits were
conducted for participants with existing or newly developed pressure injuries, and the PUSH scale
was applied.
Statistical Analysis
The study included 78 participants. Data were analyzed using IBM SPSS Statistics version 23.
Descriptive statistics were used for categorical and numerical variables. Independent samples t-test
and Mann–Whitney U test were used for between-group comparisons. Changes over time were
analyzed using paired samples t-test, repeated measures analysis of variance, Cochran’s Q test,
and Wilcoxon test. Chi-square test was used for categorical comparisons. Statistical significance
was set at p < 0.05.
