Background

• The guidelines to Article 14 of the WHO FCTC encourages

the promotion of cessation through the implementation of

• ther demand reduction measures in the FCTC.
• Yet, only limited empirical data is available on the

mechanism linking these key policy interventions to one another with regards their contributions to promoting quit attempts.

• This study therefore sought to quantify the relative effects
• f three policy interventions namely health provider advice,

pricing policy and workplace smoking ban on quit attempt among a nationally representative sample of South African Adult smokers (n= 688).

Methods

• The a priori model was specified based on the theory of

planned behaviour and tested to see how well it fits our data using SEM (AMOS 19.0).

• Model was adjusted by removing non-significant pathways

(bootstrap standardized estimates) and modified further based on inspection of modification indices.

• Adequacy of model fit – chi-square statistics (>0.05),

Normed Fit Index (NFI) and Goodness of fit Index (GFI) of >0.9 and RMSEA ≤ 0.08.

Results & Conclusions:

• 58.8% reported having made recent quit attempt, but only 25%

reported having ever been advised by a health provider to quit.

• Health concerns (59.7%) and high cost of cigarettes (47.6%) were

cited as the most common reasons for wanting to quit.
