The Effect of Guided İmagery Applied Before and After Surgery on Surgical Anxiety, Pain and Analgesic 
Consumption in Patients Undergoing Total Joint Arthroplasty: A Randomized Controlled Trial Study Protocol 
and Statistical Analysis of a Randomized Controlled Trial 
 
 
 
 
Without intervention, anxiety level measurement 
using the “Surgical Anxiety Scale” and “Surgical- 
Specific Anxiety Scale” at the end of the 
intervention group's application (70 minutes after 
the first application, 60 minutes after subsequent 
applications) 
Measure pain intensity using the “NRS” at 48 and 
72 hours post-surgery and re-measure 60 minutes 
after the measurements. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Intervention and Control Group 
Working Protocol and Statistical Analysis 
 
 
Obtaining consent from patients using the 
“Participant Consent Form” 
Implementation of the “Patient Identification 
Information Form” 
Implementation of the “Surgical Anxiety Scale” 
and the “Surgical-Specific Anxiety Scale 
Intervention Group 
Control Group 
 
 
Guided imagery with the Relaxation Exercises CD 
one day before surgery (midday-evening) 
Measurement of anxiety levels using the “Surgical 
Anxiety Scale” and “Surgery-Specific Anxiety Scale” 
at the end of the session 
Pain intensity measurement using the “NRS” 48 
hours after surgery before the intervention, 
immediately after the intervention (at 60 minutes), 
and 72 hours after surgery before the intervention and 
immediately after the intervention (at 60 minutes) 
Intervention and Control Group 
Evaluate analgesic consumption on 
the 2nd and 3rd days after surgery 
using the “Analgesic Consumption 
Tracking Form” 
 
The statistical analyses of the study will be performed using the SPSS 29.0 and R-Studio software 
packages. Descriptive statistics for the qualitative variables included in the study will be presented as 
frequencies and percentages, while quantitative variables will be presented as means, standard 
deviations, medians, minimum, and maximum values. The normality of quantitative variables will be 
examined using the Shapiro Wilk test. Independent sample t-tests and Mann Whitney U tests will be 
used for independent group comparisons of variables, while dependent sample t-tests and Wilcoxon 
tests will be used for dependent group comparisons. Relationships between quantitative variables will 
be evaluated using Pearson and Spearman correlation coefficients. Relationships between quantitative 
variables will be evaluated using Pearson and Spearman correlation coefficients. In all statistical 
comparisons in the study, results with a p-value below 0.05 will be considered statistically significant.
