The study is guided by the following research question: To what extent is a therapeutic program based on psychosocial support strategies effective in reducing feelings of loneliness among kidney disease patients? To achieve the objectives of the study, a quasi-experimental design was used alongside a case study approach, by applying a therapeutic program to a sample of 04 cases (02 males and 02 females) suffering from renal failure. The UCLA Loneliness Scale (Russell) was also used. The results showed statistically significant differences between the pre-test and post-test measurements in favor of the post-test, indicating the effectiveness of the program in reducing feelings of loneliness. The findings also revealed no significant differences between the post-test and follow-up measurements, which reflects the sustainability of the program’s effect. In addition, a high effect size was recorded, confirming the strength and effectiveness of the applied intervention. Accordingly, the study concluded that the therapeutic program based on psychosocial support strategies is an effective intervention in reducing loneliness among patients with renal failure and contributes to improving their psychological and social well-being.otherTherapeutic programPsychosocial supportLonelinessRenal failureThesis
