Table 3 Factors Extracted in Systematic Reviewa
From: Systematic review of control groups in nutrition education intervention research
Description of… |
1. … overall intervention content (i.e., content provided) |
2. … how intervention was tailored to participants |
3. … how intervention was delivered (e.g., individual or group) |
4. … intervention material type used to provide content (e.g., curriculum, website, brochure, etc.) |
5. … total duration of intervention: (e.g., 6 weeks) |
6. … intervention setting (e.g., WIC office, home) |
7. … individual sessions |
a. number of individual sessions or # of interactions (e.g., newsletters) |
b. duration of individual sessions or length of materials (e.g., #pages) |
c. frequency of individual sessions (e.g., 1 session weekly for 6Â weeks) |
d. content of each session/interaction (e.g., week 1: carbohydrates; week 2: protein, etc.) |
e. duration of each main component of each individual session (e.g., 10 min on food safety lecture, 30 min on food preparation activities; 1 page on dairy products, ½ page on fruits) |
8. … procedures for standardization of intervention across centers/researcher staff/practitioners/implementers (e.g., personnel guided by manuals, guidelines, standard operating procedures, training; participants used standardized materials such as newsletters, videos, websites, curricula) |
9. … procedures for assessing intervention implementation with fidelity to that planned (e.g., staff supervised during implementation or videotaped/observed to ensure implementation was as planned; staff surveys to describe what they did during the intervention) |
10. … procedures for blinding participant and researcher to treatment group assignment. If researchers were not blind, procedures for preventing differential treatment. |
11. …rationale for selection of control group type. |
