Perspectives on Implementing the Patient Health Questionnaire-4 in Low-Vision Service Organizations to Screen for Depression and Anxiety

Longitudinal measurement invariance and psychometric properties of the Patient Health Questionnaire-Four in China

BACKGROUND

Depression and anxiety symptoms among medical students are often a concern. The Patient Health Questionnaire-Four (PHQ-4), an important tool for depression and anxiety screening, is commonly used and easy to administer. This study aimed to assess and update the longitudinal measurement invariance and psychometric properties of the simplified Chinese version.

METHODS

A three-wave longitudinal survey was conducted among healthcare students using the PHQ-4. Structural validity was based on one-factor, two-factor, and second-order factor models, construct validity was based on the Self-Rated Health Questionnaire (SRHQ), Sleep Quality Questionnaire (SQQ), and Rosenberg Self-Esteem Scale (RSES), and longitudinal measurement invariance (LMI), internal consistency, and test-retest reliability were based on structural consistency across three time points.

RESULTS

The results of the confirmatory factor analysis indicated that two-factor model was the best fit, and LMI was supported at three time points. Inter-factor, factor-total, and construct validity correlations of the PHQ-4 were acceptable. Additionally, Cronbach's alpha, McDonald's omega, and the intraclass correlation coefficient demonstrated acceptable/moderate to excellent reliability of the PHQ-4.

CONCLUSIONS

This study adds new longitudinal evidence that the Chinese version of the PHQ-4 has promising LMI and psychometric properties. Such data lends confidence to the routine and the expanded use of the PHQ-4 for routine screening of depression and anxiety in Chinese healthcare students.

Patient Perspectives on Portal-Based Anxiety and Depression Screening in HIV Care: A Qualitative Study Using the Consolidated Framework for Implementation Research

Electronic patient portals represent a promising means of integrating mental health assessments into HIV care where anxiety and depression are highly prevalent. Patient attitudes toward portal-based mental health screening within HIV clinics have not been well described. The aim of this formative qualitative study is to characterize the patient-perceived facilitators and barriers to portal-based anxiety and depression screening within HIV care in order to inform implementation strategies for mental health screening. Twelve adult HIV clinic patients participated in semi-structured interviews that were audio recorded and transcribed. The transcripts were coded using constructs from the Consolidated Framework for Implementation Research and analyzed thematically to identify the barriers to and facilitators of portal-based anxiety and depression screening. Facilitators included an absence of alternative screening methods, an approachable design, perceived adaptability, high compatibility with HIV care, the potential for linkage to treatment, an increased self-awareness of mental health conditions, the ability to bundle screening with clinic visits, and communicating an action plan for results. The barriers included difficulty navigating the patient portal system, a lack of technical support, stigmatization from the healthcare system, care team response times, and the novelty of using patient portals for communication. The patients in the HIV clinic viewed the use of a portal-based anxiety and depression screening tool as highly compatible with routine HIV care. Technical difficulties, follow-up concerns, and a fear of stigmatization were commonly perceived as barriers to portal use. The results of this study can be used to inform implementation strategies when designing or incorporating portal-based mental health screening into other HIV care settings.

Feasibility and potential effectiveness of the IdentifEYE training programmes to address mental health problems in adults with vision impairment

PURPOSE

Two training programmes about depression and anxiety in adults with vision impairment were developed to support eye care practitioners (ECPs) and low vision service (LVS) workers in identifying and discussing mental health problems. The purpose of this study was to evaluate the training programmes' potential effectiveness and feasibility.

METHODS

The training programmes were offered to ECPs (n = 9) and LVS workers (n = 17). All participants completed surveys pre-, mid- and post-training, and at a 4 week follow-up about the training programmes' content, effectiveness, feasibility and implementation. The Kirkpatrick model was used as a theoretical framework; linear mixed models were used to determine the potential effectiveness, and outcomes were explored during three focus group meetings.

RESULTS

Expectations were met in the majority of the participants (84.6%). Post-training, both ECPs and LVS workers reported increased confidence (β = 3.67, confidence interval (CI): 0.53-6.80; β = 4.35, CI: 1.57 to 7.14, respectively) and less barriers (β = -3.67, CI: -6.45 to -0.89; β = -1.82, CI: -4.56 to 0.91). Mental health problems were more likely addressed in both the groups (ECP β = 2.22, CI: -0.17 to 4.62; LVS β = 4.18, CI: 2.67 to 5.68), but these effects did not last in ECPs (β = -3.22, CI: -7.37 to 0.92). Variations of these learning effects between individual participants were found within both the groups, and LVS workers indicated a need to focus on their own profession. Participants provided information on how to improve the training programmes' feasibility, effectiveness and implementation.

CONCLUSION

The training programmes seemed feasible and potentially effective. Transfer of the lessons learned into daily practice could be enhanced by, for example, specifying the training programmes for healthcare providers with the same profession, introducing microlearning and incorporating mental health management into organisation policies.

Discussing depression in patients with visual impairment differs across countries: Validation of a prediction model in healthcare providers

PURPOSE

Healthcare providers often experience difficulties in discussing depression with adults with visual impairment (VI), obstructing timely referral. The purpose of this study was to examine predictors of routine discussions of depression with adults with VI from the perspective of different healthcare providers from different countries.

METHODS

Cross-sectional survey data from Welsh (N = 122), Australian (N = 94) and Dutch (N = 100) healthcare providers, that is eye care practitioners (ECPs) and low-vision care providers (LVCPs), were analysed. Multivariable logistic regression analysis was performed in the Welsh sample to determine predictors for discussing depression. Internal validation was conducted by using a bootstrap method, and the recalibrated model was externally validated in the Australian and Dutch sample.

RESULTS

Work experience in eye care services (OR 0.95; 95% confidence interval (CI) 0.92 to 0.99) and perceived barriers (OR 0.95; 95% CI 0.92 to 0.98) was found to predict discussing depression with patients. The area under the curve (AUC) of 0.73 reflected good discrimination of the model. The model showed a slightly better fit in the Australian sample (AUC = 0.77), but a poor fit in the Dutch sample.

CONCLUSION

The final prediction model was not generalizable to Dutch healthcare providers. They perceived less barriers in depression management than Welsh and Australian healthcare providers. This could be explained by differences in ECPs and LVCPs roles and responsibilities, increased attention on mental health and differences in organizing health care. Differences between healthcare providers' responsibilities and support needs should be taken into account while creating a facilitating environment to discuss depression.

Improved intention, self-efficacy and social influence in the workspace may help low vision service workers to discuss depression and anxiety with visually impaired and blind adults

Background

Depression and anxiety are common in visually impaired and blind adults, but often remain untreated in those who receive support from low vision service (LVS) organizations. This study aims to determine factors associated with discussing mental health by LVS workers.

Methods

A self-administered cross-sectional survey in one hundred LVS workers was performed. Data on current practice, symptom attribution, and determinants of the Integrated Change Model (i.e. predisposing and environmental factors, awareness, attitude, self-efficacy, social influence, confidence and barriers) were investigated. Multivariable logistic regression analysis was performed to determine predictors of discussing mental health problems in this population. Subsequently, internal validation was conducted using a bootstrapping method.

Results

Around 80% of the participants often discussed mental health with clients. Five factors were found to predict discussion of mental health: female gender (OR = 4.51; 95% confidence interval (CI) 0.98 to 21.61), higher education (OR = 3.39; CI 1.19 to 9.66), intention to discuss mental health problems (OR = 3.49; CI 1.20 to 10.15), higher self-efficacy (OR = 1.11; CI 1.02 to 1.20), and higher perceived social influence (OR = 1.15; CI 1.05 to 1.27). Good discrimination after internal validation was reflected by the area under the curve (0.850).

Conclusions

Previous studies indicate clients want healthcare providers to initiate discussions about mental health. However, still 20% of LVS workers do not discuss suspected depression or anxiety. In order to improve this, LVS organizations could address mental health as part of their care and provide training to ensure intention to discuss mental health problems, improve self-efficacy and create a supportive environment between colleagues.
