Figure 2
The horizontal axis is labeled “Measurement Point” and has markings labeled from left to right as follows: “T base”, “T post 1”, and “T post 2”. The vertical axis is labeled “Horizontal Leader Structure Schema” and ranges from 3 to 5 in increments of 0.5 units. A legend indicates that the graph plots two lines labeled “Intervention group A” and “Intervention group B”. The solid line for “Intervention group A” with square data markers starts at (T base, 3.60), rises sharply to (T post 1, 4.30), and remains nearly stable and terminates at (T post 2, 4.30). The dotted line with triangle data markers for “Intervention group B” starts at (T base, 3.62), increases slightly to (T post 1, 3.65), then rises sharply and terminates at (T post 2, 4.35). Note: All numerical data points are approximated.Non-equivalent pretest-posttest control group design. Note. Tbase = 2 weeks prior session, Tpost1 = post-intervetion for group A, pre intervention for group B; Tpost2 = 3 months after the intervention for both groups; scale ranges from 1 to 7
