Outcome Measures

Primary Outcomes (1)

• Oral Health Behavior Score

  The primary outcome measure is the Collegians' Adherence to Oral Health Behaviors and determining whether there is a change resulting from receiving the Expanded Health Belief Model-based intervention. Oral health behavior will be assessed using a structured, validated five Likert scale questionnaire (The Expanded Health Belief Model Scales for Oral Health-Preventive Behaviors) which consists of Perceived Benefits, Perceived Barriers, Self-Efficacy, Subjective Norms, Health Motivation, Cues-To-Action, and Behavioral Intention. The Adherence to Oral Health Behaviors Score (which is a better outcome if it be higher) will be compared between the intervention and control groups to determine the effectiveness of the intervention program in improving adherence of college students to oral health behavior.
