Mindfulness Intervention Theory of Change (Longitudinal Design)

Designed a 12-year evaluation framework for a daily mindfulness intervention targeting middle-school students.

Problem
Can a brief, structured mindfulness practice produce measurable long-term improvements in well-being?

Program Structure

  • 10-minute daily app-based meditation delivered post-lunch
  • Intervention and comparison schools within the same district
  • Longitudinal measurement from 6th grade through 5 years post–high school

Outcome Measure
Comprehensive Inventory of Thriving (CIT), a multi-dimensional well-being instrument.

Evaluation Design

  • Difference-in-differences (DiD) model
  • Parallel trends validation
  • Explicit internal validity threat analysis

PHQ-2 / PHQ-9 Screening Workflow Assessment

Human factors and workflow analysis of a depression screening and follow-up process in primary care.

Problem
Identify reliability breakdown points in screening completion and follow-up adherence.

Approach

  • Workflow mapping
  • Hierarchical Task Analysis (HTA)
  • Structured evaluation plan for usability and process risk

Program Evaluation Design

Developed a full evaluation framework for a policy/program intervention.

Problem
Translate program goals into measurable indicators under operational constraints.

Approach

  • Logic model development
  • Indicator selection
  • Data source identification
  • Internal validity and bias assessment
