Jacobson and Truax Method: evaluation of the clinical effectiveness of a home care program after prostatectomy

Abstract

Objective:to exemplify the applicability of the Jacobson and Truax Method in a nursing intervention study that analyzed the effectiveness of a home care teaching program after radical prostatectomy. Method:this is a descriptive study concerning the applicability of the Jacobson and Truax Method in the data analysis of a clinical trial. The intervention consisted of a teaching program for hospital discharge after radical prostatectomy through oral guidance, writing, and telephonic reinforcement. Thirty-four men participated in the intervention group and 34 men participated in the control group. A reliable index of change and clinical significance was calculated for the knowledge variable in both groups. Scatterplots were presented to demonstrate the effectiveness of the method. Results:for 30 individuals in the intervention group, the intervention presented clinically relevant change than in knowledge. In the control group, none of the 34 individuals presented clinical significance of the results related to this variable, that is, the statistical significance identified by the inferential tests did not have clinically relevant changes in the knowledge variable. Conclusion:the educational intervention carried out through the combination of oral, written and telephone counseling was shown to be clinically effective in improving knowledge about home care.

Relaxation intervention to improve diabetic foot ulcer healing: Results from a pilot randomized controlled study

“…As a complement to the analysis of statistical significance of differences over time and considering that the main aim of a pilot trial is to assess feasibility, the analysis of reliable and clinically significant change, according to Jacobson and Truax's method, was conducted in the sample of EG and ACG participants that completed the respective four sessions. This method proposes a comparative analysis between pre and post‐intervention scores in order to analyse whether the differences between participants represent reliable changes and are clinically relevant 51–54 . To calculate the reliable change index, standard deviation at baseline from the sample that completed the four sessions of EG/ACG was used, as well as the McDonald Omega of measures in the total sample ( N = 54), were used.…”

[51][52][53][54] To calculate the reliable change index, standard deviation at baseline from the sample that completed the four sessions of EG/ACG was used, as well as the McDonald Omega of measures in the total sample (N = 54), were used. Following Jacobson and Truax's method, in order to assess whether the changes were clinically meaningful, criterion A was adopted, which is used when normative data for the functional (non-clinical) population are not available.…”

“…Positive and negative values in this score indicate an increase and decrease. Therefore, a value that moves between +1.96 and -1.96 is interpreted as no significant change or no change (Mata et al, 2018;Morley, 2018).…”
