NCT06053307

Brief Summary

In this study, using three phases, the investigators will use an iterative development approach to refine a behavioral intervention for managing concomitant psychosocial distress in glaucoma. Phase 1: The investigators will begin by developing a baseline intervention using strategies from Acceptance and Commitment Therapy (ACT), and delivered using a mobile application. Phase 2: The investigators will refine the baseline intervention for glaucoma patients using qualitative interviews conducted with primary open-angle glaucoma (POAG) patients with psychosocial distress (N=20), and health professionals (N=5). Phase 3: Finally, the investigators will measure acceptability and feasibility of the refined intervention through a single-armed pilot study (N=25). The investigators hypothesize that the refined intervention will yield an acceptable and feasible intervention in a POAG patient population, setting the stage for a future efficacy study.

Outcome Measures

Primary Outcomes (4)

  • Change in psychosocial distress

    Measured using the Hospital Anxiety and Depression Scale (HADS). The scale ranges from 0-42 with higher values indicating higher distress.

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in psychosocial distress

    Measured using the Subjective Unit of Distress (SUDS) scale. The scale ranges from 0-10 with higher values indicating higher distress.

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in vision-related quality-of-life (QoL)

    Measured using the National Eye Institute (NEI)- Visual Functioning Questionnaire (VFQ) 9. The scale ranges from 0-100 with higher values indicating higher vision-related QoL.

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in health-related QoL

    Measured using the CDC Health-Related Quality-of-Life 4-Item Scale. For our outcome we will use the self-rated scale from Poor to Excellent, which has a scale from 1-5, with higher values indicating higher QoL.

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

Secondary Outcomes (5)

  • Change in psychological flexibility

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in disease acceptance

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in self-efficacy

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in mindfulness

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

  • Change in perceived social support

    Measures will be administered at baseline (A1), immediately post-intervention (A2), and 1-month post treatment assessment (A3).

Other Outcomes (4)

  • Study feasibility

    Collected within a one-year period from the beginning of recruitment.

  • Study feasibility

    Collected at the post-intervention assessment (A2), six-weeks after the initial assessment.

  • Study acceptability

    Collected at the post-intervention assessment (A2), six-weeks after the initial assessment.

  • +1 more other outcomes

Study Arms (1)

VISION-ACT: Acceptance commitment therapy via a mobile-application

EXPERIMENTAL

The arm will pilot a behavioral intervention to treat psychosocial distress in patients with glaucoma using acceptance commitment therapy (ACT) delivered via a mobile-application, called VISION-ACT. The intervention will be developed and refined using qualitative feedback from glaucoma patients and healthcare stakeholders.

Behavioral: Acceptance commitment therapy

Interventions

The baseline intervention will use ACT, a psychological intervention based on modern behavioral psychology, including relational frame theory, that uses acceptance and mindfulness strategies, along with commitment and behavior-change strategies to increase psychological flexibility. The proposed intervention will be delivered over a 6-week period, with each week including content related to one of the six tenets of ACT: cognitive defusion, acceptance, contact with the present moment, the observing self, values, and committed action. Each week will include educational material, skills work, and homework. The intervention will be delivered via a mobile application.
