Adolescent non-suicidal self-injury: The moderating influence of social support utilization on depression

Figure 2 Johnson-Neyman plot of the moderating effect of social support utilization on the relationship between depression and non-suicidal self-injury. This Johnson-Neyman plot illustrates the conditional effect of depression on non-suicidal self-injury (NSSI) across different levels of social support utilization. The red shaded area represents the region of significance (P < 0.05), while the blue area indicates non-significance. The narrowing of the confidence interval (shaded area around the line) from left to right suggests increased precision in the estimate at higher levels of social support utilization. The observed range of social support utilization in the study was 6 to 30. The effect of depression on NSSI remains significant but decreases as social support utilization increases, as indicated by the downward slope of the line. The Johnson-Neyman technique reveals that the relationship between depression and NSSI is significant for all observed values of social support utilization in this study. NSSI: Non-suicidal self-injury; NS: No significance.
