From: Psychographic predictors of intention to use cervical cancer screening services among women attending maternal and child health services in Southern Ethiopia: the theory of planned behavior (TPB) perspective

   Items Scale Scoring Outcome
Dimension (Direct measures)
 1. Intention (Ii) 4 Likert scale \( \sum \limits_1^4 Ii \) Intention score

 3. Subjective norms (SN) 4 Likert scale \( \sum \limits_{i=1}^4 SNi \) “SN” score
 4. Perceived behavioral control (PBC) 4 SDS \( \sum \limits_{i=1}^4 PBCi \) “PBC” score
Beliefs based (Indirect measures)
 1. Behavioral beliefs (bbi) 6 Likert scale \( \sum \limits_{i=1}^6 bbi\ast ebbi \) “IA” score
 2. Evaluation of the beliefs (ebbi) 6 Likert scale

Power of control (pci)
6 Likert scale \( \sum \limits_{i=1}^6 cbi\ast pci \) “IPBC” score
