Objectives
A reason for the lack of interest in physical fitness testing in mental healthcare is limited time among existing staff. This cross‐sectional study investigated the test–retest reliability of the 2‐min walk test (2MWT) and its concurrent validity with the 6‐min walk test (6MWT) in Ugandan patients with depression. We also explored practice effects and assessed the minimal detectable change (MDC) and clinical correlates with the 2MWT.
Methods
This is a cross‐sectional study executed in Butabika National Referral Hospital in Kampala, Uganda. Fifty Ugandan patients with depression (15 women; median age = 29.0 years) performed twice a 2MWT, once a 6MWT, and completed the Simple Physical Activity Questionnaire (SIMPAQ), and Brief Symptoms Inventory‐18 (BSI‐18).
Results
The median (interquartile) 2MWT score on the first and second test were 125.5 (59.2) meters and 131.0 (57.0) meters (p = .28). The intraclass correlation was.96 (95% confidence interval [0.94, 0.98]). The MDC was 23.5 m for men and 23.4 m for women. There was no evidence of a practice effect. Scores on BSI‐18 depression, SIMPAQ walking, and SIMPAQ incidental physical activity explained 66.3% of 2MWT score variance.
Conclusion
The 2MWT is a reliable test, which can be conducted without any special equipment or substantial time demands, to provide a valid assessment of the functional exercise capacity in outpatients with depression.
