Trial results for an implementation intervention aimed at supporting the delivery of behavioral weight loss programs for Obesity were posted on ClinicalTrials.gov on 2025-08-20. The study reported an overall mean difference of 5.5 (95.0% confidence interval: 3.9 to 7.1) for a comparison of baseline and 6 months across both intervention groups.
Background
Obesity and overweight are significant public health challenges, often co-occurring with mental health conditions. Effective weight management programs are crucial, but their successful implementation in community mental health settings can be complex. This pilot randomized clinical trial investigated strategies to enhance the delivery of an evidence-based behavioral weight loss program, focusing on improving the capabilities of staff coaches within these programs.
Trial design
This pilot randomized clinical trial enrolled 92 participants and investigated strategies for implementing weight management interventions for Overweight and Obesity. The trial compared an "Enhanced Implementation Intervention- Staff Coach" group against a "Standard Implementation Intervention- Staff Coach" group. The study aimed to test strategies to increase the implementation of a behavioral weight loss program in community mental health programs.
Key results
The trial reported several key measurements related to staff coaches' knowledge and self-efficacy:
- Knowledge of ACHIEVE Intervention Topics:
- For the Enhanced Implementation Intervention- Staff Coach group, the mean score was 16.1 (Standard Deviation 2.8) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, the mean score was 13.3 (Standard Deviation 3.5) on a scale.
- In another measurement for the Enhanced Implementation Intervention- Staff Coach group, the mean score was 19.9 (Standard Deviation 1.7) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, this mean score was 20.5 (Standard Deviation 1.4) on a scale.
- Self-efficacy to Deliver ACHIEVE Intervention:
- For the Enhanced Implementation Intervention- Staff Coach group, the mean score was 8.9 (Standard Deviation 0.7) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, the mean score was 9.3 (Standard Deviation 1.1) on a scale.
- Another mean score for the Enhanced Implementation Intervention- Staff Coach group was 8.4 (Standard Deviation 1.4) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, this mean score was 8.9 (Standard Deviation 0.7) on a scale.
- A third mean score for the Enhanced Implementation Intervention- Staff Coach group was 9.0 (Standard Deviation 1.0) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, this mean score was 9.5 (Standard Deviation 1.0) on a scale.
- A fourth mean score for the Enhanced Implementation Intervention- Staff Coach group was 8.1 (Standard Deviation 1.6) on a scale.
- For the Standard Implementation Intervention- Staff Coach group, this mean score was 9.1 (Standard Deviation 0.6) on a scale.
Key analyses reported mean differences:
- A Mean Difference (Net) of 5.5 (95.0% confidence interval: 3.9 to 7.1) was observed for the comparison of baseline and 6 months across both groups.
- The between-groups differences of change between baseline and 6 months showed a Mean Difference (Net) of -0.6 (95.0% confidence interval: -2.3 to 1.1).
- For the leading behavioral weight loss group baseline to 6 months comparison, the Mean Difference (Net) was -0.5 (95.0% confidence interval: -1.4 to 0.4).
- The leading behavioral weight loss group between group comparison of change showed a Mean Difference (Net) of -0.05 (95.0% confidence interval: -2.0 to 1.0).
- For completing weigh-ins baseline to 6 month comparison, the Mean Difference (Net) was -0.6 (95.0% confidence interval: -1.4 to 0.2).
- Completing weigh-ins between groups comparison of change showed a Mean Difference (Net) of -1.0 (95.0% confidence interval: -2.5 to 0.5).
What this means
This pilot trial provides insights into the effectiveness of implementation strategies for behavioral weight loss programs in community mental health settings. The overall positive mean difference of 5.5 observed across both groups from baseline to 6 months suggests that staff coaches experienced some improvement in relevant metrics, such as knowledge or self-efficacy, over time. However, most of the reported between-group mean differences had 95.0% confidence intervals that crossed zero, indicating that the enhanced implementation intervention did not consistently demonstrate a statistically significant advantage over the standard approach in these specific comparisons. These findings can inform future efforts to optimize the delivery of crucial health interventions in integrated care settings.
