Classifying Patients with Chronic Pelvic Pain into Levels of Biopsychosocial Dysfunction Using Latent Class Modeling of Patient Reported Outcome Measures

Figure 1

Standardized scores in biopsychosocial superdomains for the four latent classes’ model. The PROMIS domains are t score adjusted so that the population mean is 50 and 10 points represents one standard deviation. All domains are scored so that higher scores indicate more of what is being measured. For pain, negative affect, and fatigue high scores are worse. For social function low scores are worse. Pain and social function provide the clearest distinction and categorical progression of the latent classes.
