Brief Smartphone Treatment Study for Generalized Anxiety Disorder
This study is looking into whether a short smartphone-based mindfulness program can help people with Generalized Anxiety Disorder (GAD). You would use a smartphone app called PACO. One group will get a mindfulness program that regularly prompts them to practice mindfulness skills, while another group will use a self-monitoring version of the app. Researchers want to see if the mindfulness program can reduce anxiety symptoms and repetitive negative thoughts. To join, you need to be an adult with GAD, either a student at Penn State University or an adult who expressed interest through the PSU StudyFinder portal, and interested in seeking treatment. The study is currently unclear about its recruitment status and plans to enroll 300 people.
- Study design
- This is an interventional study planning to enroll 300 participants. It compares a mindfulness intervention to a placebo, both delivered via a smartphone app.
- What's involved
- You would use a smartphone app that prompts you to practice skills or self-monitor 5 times a day for 14 days.
- Compensation
- Not stated in the trial record.
- Follow-up
- Researchers will check your anxiety symptoms and repetitive thoughts at 14 days after treatment and again at 6 weeks after you are assigned to a group.

What this trial measures
- Change from Baseline Generalized Anxiety Disorder Symptoms at 14-Day Post-TreatmentBaseline to 14-Day Post-Treatment
Generalized Anxiety Disorder Questionnaire-IV (GAD-Q-IV) with categorical ('Yes' for presence and 'No' for absence) and continuous response formats (0 = not at all to 8 = very severely) (Newman et al., 2002) (Item 1 to Item 14 self-report; possible range = 0-12). Generalized Anxiety Disorder Questionnaire-Dimensional (Item 15 to Item 30) with consistent continuous 8-point Likert scale response formats that measures the frequency, intensity, uncontrollability, and degree of excessive worry (e.g., 0 = Always in control to 8 = Never in control) (Newman et al.) (possible range = 0-128). Larger reduction in score denote better outcome.
- Change from Baseline Generalized Anxiety Disorder Symptoms at 6-Week Post-RandomizationBaseline to 6-Week Post-Randomization
Generalized Anxiety Disorder Questionnaire-IV (GAD-Q-IV) with categorical ('Yes' for presence and 'No' for absence) and continuous response formats (0 = not at all to 8 = very severely) (Newman et al., 2002) (Item 1 to Item 14 self-report; possible range = 0-12). Generalized Anxiety Disorder Questionnaire-Dimensional (Item 15 to Item 30) with consistent continuous 8-point Likert scale response formats that measures the frequency, intensity, uncontrollability, and degree of excessive worry (e.g., 0 = Always in control to 8 = Never in control) (Newman et al.) (possible range = 0-128). Larger reduction in score denote better outcome.
- Change from Baseline Perseverative Cognitions at 14-Day Post-TreatmentBaseline to 14-Day Post-Treatment
The 45-item PCQ assessed perseverative cognitive traits linked to anxiety, depressive, and obsessive-compulsive symptoms. Respondents endorsed on a 6-point Likert scale (0 = strongly disagree to 5 = strongly agree). Further, the PCQ-45 comprised six factors: dwelling on the past; expecting the worst; lack of controllability; thoughts discrepant with ideal self; preparing for the future; searching for causes and meanings. Additionally, the PCQ had strong two-week retest reliability, discriminant validity, and convergent validity (Szkodny \& Newman, 2019). A total score for PCQ was computed by summing the mean scores from each subscale (total possible score = 0-30). Larger reduction in score denote better outcome.
