Overall, n = 443 dentists responded, and of these, 410 (92.6%) were eligible and included in the final sample. N = 33 (7.4%) were excluded: 10 did not provide consent, 16 were pedodontists, 5 retirees, and 2 dentists residing outside of Israel.
Among the 410 eligible respondents, 251 (62.0%) were male. The mean age of the participants was 49.9 (SD 12.4). The majority never smoked cigarettes or used other nicotine or tobacco products (n = 258, 62.9%). Less than a fifth (n = 52, 12.8%) currently smoked cigarettes, with very few (6.1%, n = 25) currently using other products (primarily hookah, electronic cigarettes and cigars). Of the entire sample, only 1.7% (n = 7) reported currently using both cigarettes and other tobacco products. More than a third of the sample were specialists (n = 157, 38.3%). Most primarily worked in the private sector (n = 287, 70.3%) and had not participated in a SCC training workshop (n = 354, 86.3%). Sociodemographic, smoking characteristics and professional characteristics of the entire sample (n = 410) are presented in Table 1.

Knowledge and attitudes
The mean knowledge score was 2.58 (out of 10), SD = 1.51. The mean attitude score was 2.65 (out of 5), SD = 0.60. Rates of agreement for each TDF attitude are presented in Fig. 1 (n = 410). Overall, participants tended to display negative attitudes in most of the domains. However, 70.7% (n = 290) did not believe that providing SCC to their patients is frustrating and 69.8% (n = 286) agreed that providing SCC would not offend their patients.
Performance of all the 5A’s “Often and Always”:
Overall performance of all 5A’s was low with only 57/405 participants (14.1%) reporting completing all the 5A’s ‘often or always’ (Fig. 2). While 76.0% (n = 310/408) of dentists perform ‘Ask’ and 72.1% (n = 294/408) perform ‘Advise’, considerably less dentists performed the following three steps, with performance reduced with each step – 49.0% (n = 200/408) performed ‘Assess’, 36.7% (n = 150/408) performed ‘Assist’, and 21.5% (n = 88/408) performed ‘Arrange’.
Among those who performed all the 5A’s ‘often or always’, a higher rate of participants were specialist (n = 31/57, 54.4%), compared to the non-performers group, where only 36.2% (n = 126/348( were specialist, p = .012 (Table 1). Participants with fewer years as specialists demonstrated a statistically higher performance of the 5A’s (mean = 13.25, SD 8.94) compared to those with more years as specialists (mean = 17.65, SD 12.52; p = .049). Training workshop participants exhibited a statistically higher rate of 'often or always' performing all the 5A's (n = 15, 26.3%) compared to non-performers (n = 41, 11.8%; p = .006). The mean knowledge score (3.07, SD 1.64) and composite attitude score (3.13, SD 0.58) were higher among participants who ‘often or always’ performed all the 5A’s, compared to non-performers (p = .008 and p < .001, respectively).
Table 2 provides the results of the multivariate analyses for factors associated with ‘often and always’ performing all 5A’s. There was a significant interaction between workshop participation and the composite attitude score (pint = .018). Therefore, we present the full model with the interaction variable, and stratified by workshop participating in the workshop.

Specialists had better odds of ‘often or always’ performing the 5A’s (adjusted Odds Ratio (OR) = 2.01, p = .022). Knowledge score was not associated with performance in any of the adjusted models. Attitude score was significantly associated with performance in both workshop participants and non-participants. However, the association was stronger among workshop participants (OR = 12.89, 95% Confidence Intervals (CI) 2.06–80.69, p = .006) than among non-participants (OR = 5.64, 95% CI 2.92–10.89, p < .001).
Performance of Ask and Advise “Always”:
Overall, 34.1% (n = 139) of participants reported ‘always’ performing ‘Ask’ and ‘Advise’ (Table 1). Participants who never smoked exhibited a higher rate of 'always' performing 'Ask and Advise' (n = 107, 77%, p = .007). A similar association was observed for users of other smoking/tobacco products, with 89.2% (n = 124) of performers reporting never using them (p = .024), and 'ever users' displaying a significantly lower rate of 'always' performing 'Ask and Advise' (n = 37, 26.6%) compared to not performing (n = 115, 42.8%), p = .002. Specialists and workshop participants also demonstrated higher rates of ‘always’ performing 'Ask and Advise' (n = 66, 47.5%, p = .010, and n = 30, 21.6%, p = .001, respectively). Additionally, participants who 'always' performed 'Ask and Advise' exhibited a higher composite attitude score (mean = 2.83, SD 0.60) compared to non-performers (mean = 2.56, SD 0.57), p < .001.
Logistic regression results for ‘always’ performing ‘Ask and Advise’ is depicted in Table 3. Specialists had better odds of ‘always’ performing ‘Ask and Advise’ (adjusted OR = 1.71, p = .022). Participants with more positive attitudes also performed better (adjusted OR = 2.48, p < .001). The OR of ‘always’ performing ‘Ask and Advise’ was about half in ever smokers (or tobacco users) compared to never smokers (adjusted OR = 0.48, p = .004). Workshop participation was not significant in the adjusted regression (p = .07).
