Testing the Effectiveness of Cognitive Behavioral Therapy in Relieving Nurses' Ageism Toward Older Adults: A Randomized Controlled Trial

Background

Although cognitive-behavioral therapy (CBT) techniques are well known for targeting psychological distresses, to date, no study has investigated their effectiveness in relieving death anxiety and ageism among nurses.

Methods

A parallel randomized controlled trial was conducted according to the CONSORT guidelines during October 2019 at the university hospital. A total of 110 nurses were selected through proportional stratified sampling and randomly assigned to the experimental and control groups. The intervention consisted of six two-hour training sessions delivered over five modules with the integration of different CBT exercises. The effect of CBT was assessed by measuring the differences in the students’ responses to a series of validated questionnaires of study variables pre-test (before the training sessions) and post-test (after the training sessions). Clinical registration was completed at ClinicalTrial.gov (ID: NCT04319393).

Results

Overall, using CBT techniques led to significant improvements in the study outcomes. At postintervention, the nurses who had received CBT training had significantly better self-esteem and interpersonal relationships, a greater sense of symbolic immortality, and less death anxiety and ageism than the nurses in the control group.

Conclusions

CBT is an effective evidence-based psychological intervention for relieving nurses’ ageism towards older adults. The psychological well-being of nurses caring for older adults is crucial, and new techniques should be adopted to relieve nurses’ accumulated stress and decrease their death anxiety. Future studies which investigate the effectiveness of CBT on other forms of discrimination, such as racism and sexism in healthcare settings, are recommended.

Effect of Cognitive Behavioral Therapy Versus Interpersonal Psychotherapy in Patients with Major Depressive Disorder: A Meta-analysis of Randomized Controlled Trials

BACKGROUND

Practice guidelines have recommended cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT) as the treatment of choice for major depression disorder (MDD). However, whether one therapy is better than the other remains inconclusive. The aim of this study was to compare the treatment efficacy of the two treatment approaches for MDD.

METHODS

Using the terms "cognitive behavior therapy or cognitive therapy or CBT or CT or cognitive behavioral therapy" and "interpersonal psychotherapy or IPT," we systematically searched PubMed, Psyclnfo and Chinese National Knowledge Infrastructure databases up to February 2017. The language was restricted to be English and Chinese. Therapeutic outcomes, characteristics, and research quality were then extracted and analyzed independently. In accessing the included studies, we followed the criteria suggested by the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

Data for 946 patients from 10 randomized controlled trials were included in the study. Methodological quality was not optimal in most trials. Meta-analysis showed a mean difference (MD) of -1.31, 95% confidence interval (CI) (-2.49, -0.12) (P < 0.05) in favor of CBT according to the Beck Depression Inventory (BDI), and however, we did not found any statistically significant difference between CBT and IPT on the Hamilton Rating Scale for depression (HRSD) (MD -0.90, 95% CI [-2.18, 0.38]). Subgroup analyses for the studies in which patients were treated only by psychotherapy (MD -1.26, 95% CI [-2.78, 0.35]) and for those which offered more sessions of therapies (MD -0.82, 95% CI [-2.23, 0.59]) showed there was no significant difference between CBT and IPT according to BDI.

CONCLUSIONS

Differences in treatment efficacy seem to vary according to different outcome measures. CBT shows an advantage over IPT for MDD according to BDI, and there is no significant difference between the two according to HRSD. These results should be interpreted with caution.
