  Purpose

This study determines if there is a difference in dental students' attitudes, perceived barriers, subjective norms, perceived skills, self-efficacy, intentions to provide cessation treatment, and cessation knowledge in those students receiving a tobacco cessation lecture along with practice sessions using standardized patients and those students receiving only a tobacco cessation lecture. The study determines if dental students' use of tobacco affects their intent to provide cessation treatment to patients, and if the time between receiving the lecture and participating in the practice sessions using standardized patients makes a difference in dental students' attitudes, perceived barriers, subjective norms. perceived skills, self-efficacy, intentions to provide cessation treatment, and cessation knowledge.

Primary Outcome Measures:
  • Change From Baseline in Attitude Score [ Time Frame: Questionnaire 1 (baseline/pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    The attitude variable was computed by adding the values from two questionnaire items to assess the level agreement with statements: 1.) "It is important for members of the profession to discuss tobacco use with patients" and 2.) "A brief intervention (3 minutes) for tobacco cessation with my patients would be effective." The rating scale was: 0 = strongly disagree, 1 = moderately disagree, 2 = somewhat disagree, 3 = neither disagree or agree, 4 = somewhat agree, 5 = moderately agree, and 6 = strongly agree. A higher value represents participants' more positive attitude toward providing tobacco cessation treatment (Range:0-8). The difference in the attitude from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total value of the variable at Questionnaire 1 from the total value at Questionnaire 2.

  • Change From Baseline in Perceived Barriers Score [ Time Frame: Questionnaire 1(baseline/pre-lecture) to Questionnaire 2(post-lecture or post-lecture and counseling /debriefing sessions) ] [ Designated as safety issue: No ]
    The perceived barriers variable was computed by adding the total number of barriers reported by participants. Participants were asked to select all factors that may limit their ability to counsel tobacco users during every visit. The rating scale for reporting barriers was: 0 = no and 1 = yes. A higher value represents a higher number of barriers to providing tobacco cessation treatment reported by participants(Range: 0-11). The difference in perceived barriers from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total number of perceived barriers at Questionnaire 1 from the total number of perceived barriers at Questionnaire 2.

  • Change From Baseline in Subjective Norms Score [ Time Frame: Questionnaire 1 ( baseline/pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    Subjective norms are beliefs that people who influence your actions approve or disapprove of the behavior. The subjective norms variable was computed by adding the values of six questions to assess the participants' level of perceived social pressures to counsel patients in quitting tobacco use. Questions wer rated on a seven-point Likert scale; higher point values indicate a perceived social norm more supportive of counseling patients in quitting tobacco use(Range: 0-36). The difference in the subjective norms score from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total number of participants' subjective norms at Questionnaire 1 from the total number of participants' subjective norms at Questionnaire 2.

  • Change From Baseline in Perceived Skills Score [ Time Frame: Questionnaire 1(baseline/pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    The perceived skills variable was computed by adding the values of seven questions that assessed the participants' perceived level of tobacco cessation treatment skills from poor to excellent. The rating scale was: 0 = poor, 1 = fair, 2 = good, 3 = very good, and 4 = excellent. A higher value represents a higher level of tobacco cessation treatment skills perceived by participants (Range: 0-28). The difference in the participants' perceived skills from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total value of perceived skills at Questionnaire 1 from the total value of perceived skills at Questionnaire 2.

  • Change From Baseline in Self-efficacy Score [ Time Frame: Questionaire 1 (baseline/pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    Self-efficacy represents an individual's confidence in his/her ability to perform a behavior. The self-efficacy variable was computed by adding the values of ten questions to assess the participants' self-efficacy to counsel patients to quit tobacco use. The rating scale was: 0 = not at all confident, 1 = not very confident, 2 = moderately confident, 3 = very confident, and 4 = extremely confident. A higher value represents participants' higher level of confidence in providing tobacco cessation treatment (Range: 0-40). The difference in participants' self-efficacy from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total value of self-efficacy at Questionnaire 1 from the total value at Questionnaire 2.

  • Change From Baseline in Intentions Score [ Time Frame: Questionnaire 1 (baseline/pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    Participants' intentions to provide tobacco cessation treatment were computed by adding values from thirteen questions to assess dental students' intent to counsel patients to quit tobacco use. The rating scale was: 0 = never, 1 = rarely, 2 = sometimes, 3 = almost always, 4 = always (every visit). A higher value represents participants' stronger intentions to provide tobacco cessation treatment (Range: 0-52). The difference in participants' intentions to provide tobacco cessation treatment from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total value of participants' intentions at Questionnaire 1 from the total value of participants' intentions at Questionnaire 2.

  • Change From Baseline in Tobacco Cessation Knowledge Score [ Time Frame: Questionnaire 1 (pre-lecture) to Questionnaire 2 (post-lecture or post-lecture and counseling/debriefing sessions) ] [ Designated as safety issue: No ]
    The tobacco cessation knowledge variable was computed by adding the participants' total number of correct answers of the ten knowledge questions. The rating scale was: 0 = incorrect and 1 = correct. A higher value represents participants' higher level of tobacco cessation treatment knowledge (Range: 0-10). The difference in the tobacco cessation knowledge from Questionnaire 1 to Questionnaire 2 was computed by subtracting the total number of participants' correct answers at Questionnaire 1 from the total number of participants' correct answers at Questionnaire 2.

Detailed Description:

The experimental study has a pretest-posttest design. It evaluates the changes to dental students' attitudes, perceived barriers, subjective norms, perceived skills, self-efficacy, intentions to provide cessation treatment, and tobacco cessation knowledge between those students receiving a lecture along with practice sessions using standardized patients and those students receiving only a lecture. Dental students will be invited to complete two questionnaires. The control group of dental students will complete the first questionnaire before the lecture and the second questionnaire after the lecture. The experimental group of dental students will complete the first questionnaire before the lecture and the second questionnaire after the lecture and the practice and debriefing sessions. Subjects will include 120 first year dental students in an introductory course to clinical dentistry. The cessation training is a required activity in the course. Students are divided into small groups according to their bench or lab numbers. These numbers are assigned to the student based on the alphabetical order of their name. The eligibility criteria is: 1) Must be a first year dental student in Introduction to Clinical Dentistry 1 at the University of Louisville, and 2) Must be willing to volunteer to complete pre- and post-questionnaires about the cessation treatment educational program. The exclusion criteria is: Subject is not willing to give consent to complete the pre- and post- questionnaire.
