Table 3 Logistic regression predicting testing in the past 6 months

From: Predictors of Chlamydia Trachomatis testing: perceived norms, susceptibility, changes in partner status, and underestimation of own risk

Modela Predictors: Observed: Predicted β/SE/Wald

  1. aHere, only the significant predictors are displayed
  2. model 1: all social-cognitive determinants predicting of intention (i.e., susceptibility, attitude, outcome expectations, unrealistic optimism, and subjective, descriptive and moral norms at T0
  3. model 2: intention and susceptibility
  4. model 3: intention, multiple partners in the last six months, new partner in the last six months, and stereotypical beliefs about number of partners
  5. b,c,d,e; same letters refer to the predictor - β/SE/Wald-value combination
  6. Bold text: the overall percentage of correctly predicted cases per model
