The Effect of the Imacoco Care Psychoeducation Website on Improving Psychological Distress Among Workers During the COVID-19 Pandemic: Randomized Controlled Trial

Effectiveness of a Smartphone-Based Stress Management Program for Depression in Hospital Nurses During COVID-19 in Vietnam and Thailand: 2-Arm Parallel-Group Randomized Controlled Trial

BACKGROUND

During the COVID-19 pandemic, health care professionals experienced high levels of depression. However, extant research has not highlighted effective internet-based psychological interventions to improve the mental health in this population during the pandemic. It remains unclear whether self-guided, internet-based cognitive behavioral therapy (iCBT) programs are effective in improving the mental health of health care workers during the COVID-19 pandemic.

OBJECTIVE

The aim of this study was to evaluate the effectiveness of a smartphone-based iCBT stress management program for reducing the depression experienced by nurses in Vietnam and Thailand.

METHODS

From March to April 2022, a 2-arm, parallel-group randomized controlled trial was implemented. One arm offered a 7-week self-guided iCBT program, and the other offered treatment as usual as a control arm. Full-time nurses were recruited from 6 hospitals: 2 hospitals in Vietnam and 4 hospitals in Thailand. The primary outcome of this program was the severity of depression measured by the Depression Anxiety Stress Scale-21 items. Follow-up surveys were conducted to measure the change in depression severity at 3 months (July-August 2022) and at 6 months (October-November 2022) after baseline. Mixed modeling for repeated measures was used to test the effects of the intervention compared with the control for the follow-up.

RESULTS

A total of 1203 nurses were included in this study: 602 in the intervention group and 601 in the control group. The follow-up rate at 3 and 6 months ranged from 85.7% (515/601) to 87.5% (527/602). The completion rate for the program was 68.1% (410/602). The group difference in depression was significant at the 3-month follow-up (coefficient=-0.92, 95% CI -1.66 to -0.18; P=.02) and nonsignificant at the 6-month follow-up (coefficient=-0.33, 95% CI -1.11 to 0.45; P=.41). The estimated effect sizes were -0.15 and -0.06 at the 3- and 6-month follow-ups, respectively.

CONCLUSIONS

Our study shows that the smartphone-based iCBT program was effective in reducing depression at the 3-month follow-up among hospital nurses in Vietnam and Thailand during the COVID-19 pandemic. However, the effect size was small, and therefore, these results may not be clinically meaningful.

Association between workplace interpersonal relationships and psychological distress among care workers at elder care facilities

BACKGROUND

As the number of older people requiring care continues to increase across the globe, maintaining care workers' mental health is an important task for all countries. This study examines the association between interpersonal relationships at work and psychological distress among care workers at elder care facilities in Japan.

METHODS

This study was a secondary data analysis of cross-sectional data. There were 406 participants who were analyzed. Questions consisted of demographic variables, psychological distress, interpersonal problems in the workplace, and intention to improve interpersonal relationships. Psychological distress was evaluated using the Japanese version of the K6 scale. Factors related to psychological distress were identified by logistic regression analysis.

RESULTS

Prevalence of psychological distress was 53.2%. Care workers experiencing interpersonal problems in the workplace were 5.95 (95% CI: 3.82-9.43) times more likely to experience psychological distress than care workers without such problems. Moreover, those who displayed an intention to improve their interpersonal relationships were 0.33 times (95% CI: 0.15-0.71) less likely to experience psychological distress than those who did not.

CONCLUSIONS

This study found there is a strong association between workplace interpersonal relationships and psychological distress among care workers at elder care facilities. Therefore, experiencing interpersonal problems in the workplace may be a risk factor for psychological distress, and displaying an intention to improve one's interpersonal relationships may attenuate psychological distress.

The Effectiveness of Internet-Based Cognitive Behavioral Therapy as a Preventive Intervention in the Workplace to Improve Work Engagement and Psychological Outcomes: Protocol for a Systematic Review and Meta-analysis

BACKGROUND

Mental health has become an increasingly significant issue in the workplace. Non-health care workers are experiencing increased levels of psychological symptoms in their workplaces, especially during the COVID-19 pandemic, which limited social interactions and health service access. These conditions have a negative effect on employees' mental health and may also be associated with work-related outcomes, such as reduced levels of work engagement. Cognitive behavioral therapy (CBT) is one of the most effective methods used for treating workers with mental illness and preventing work-related psychological outcomes. The delivery of internet-based CBT (iCBT) has been established as a result of both technological improvements that have influenced health promotion and prevention components, and limited social contact and health service access.

OBJECTIVE

The purpose of this systematic review is to synthesize the best available evidence concerning the preventive effect of iCBT on employees.

METHODS

A systematic search will be conducted across 12 electronic databases, including a hand search for main journals and reference lists. Randomized controlled trials testing the effects of iCBT on psychological outcomes and work engagement among employees will be eligible. Initial keywords will cover the concepts of employees, workers, non-health care personnel, internet-based, web-based, eHealth cognitive behavioral interventions, stress, depression, anxiety, and work engagement, and then a full search strategy will be developed. Following titles, abstracts and the full text will be screened for assessment against the inclusion criteria for the review. Search results will be fully reported and presented per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent reviewers will screen and extract data, appraise methodological quality using the Cochrane risk-of-bias assessment tool, and assess overall quality of evidence with the Grading of Recommendations Assessment, Development, and Evaluation approach. A random effects meta-analysis and standardized mean differences using review manager software will be applied to synthesize the effect of iCBT based on similar outcomes.

RESULTS

This protocol was registered in the International Prospective Register of Systematic Reviews in March 2022 and is now an ongoing process. The data will be analyzed in August 2022, and the review process should be completed by December 2022. All included studies will be synthesized and presented to demonstrate the effectiveness of iCBT in decreasing psychological distress and optimizing work engagement outcomes among employees.

CONCLUSIONS

According to the findings of this study, iCBT therapies will be used to promote mental health concerns such as depressive symptoms, anxiety, psychological distress, stress, insomnia, and resilience among non-health care professionals. In addition, the results will be used to ensure the policy related to reducing psychological distress and optimizing work engagement in the workplace.

Usefulness of Implementation Outcome Scales for Digital Mental Health (iOSDMH): Experiences from Six Randomized Controlled Trials

OBJECTIVES

Measuring implementation outcomes for digital mental health interventions is essential for examining the effective delivery of these interventions. The "Implementation Outcome Scale of Digital Mental Health" (iOSDMH) has been validated and used in several trials. This study aimed to compare the iOSDMH for participants in six randomized controlled trials (RCTs) involving web-based interventions and to discuss the implications of the iOSDMH for improving the interventions. Additionally, this study examined the associations between iOSDMH scores and program completion rate (adherence).

METHODS

Variations in total scores and subscales of the iOSDMH were compared in six RCTs of digital mental health interventions conducted in Japan. The web-based intervention programs were based on cognitive behavioral therapy (2 programs), behavioral activation (1 program), acceptance and commitment (1 program), a combination of mindfulness, behavioral activation, and physical activity (1 program), and government guidelines for suicide prevention (1 program). Participants were full-time employees (2 programs), perinatal women (2 programs), working mothers with children (1 program), and students (1 program). The total score and subscale scores were tested using analysis of variance for between-group differences.

RESULTS

Total score and subscale scores of the iOSDMH among six trials showed a significant group difference, reflecting users' perceptions of how each program was implemented, including aspects such as acceptability, appropriateness, feasibility, overall satisfaction, and harm. Subscale scores showed positive associations with completion rate, especially in terms of acceptability and satisfaction (R-squared = 0.93 and 0.89, respectively).

CONCLUSIONS

The iOSDMH may be a useful tool for evaluating participants' perceptions of features implemented in web-based interventions, which could contribute to improvements and further development of the intervention.
