E-cigarette support for smoking cessation: Identifying the effectiveness of intervention components in an on-line randomized optimization experiment.

ABSTRACT:

Aims, design and setting

The aim of this study was to determine which combination(s) of five e-cigarette-orientated intervention components, delivered on-line, affect smoking cessation. An on-line (UK) balanced five-factor (2 × 2 × 2 × 2 × 2 = 32 intervention combinations) randomized factorial design guided by the multi-phase optimization strategy (MOST) was used.

Participants

A total of 1214 eligible participants (61% female; 97% white) were recruited via social media.

Interventions

The five on-line intervention components designed to help smokers switch to exclusive e-cigarette use were: (1) tailored device selection advice; (2) tailored e-liquid nicotine strength advice; (3): tailored e-liquid flavour advice; (4) brief information on relative harms; and (5) text me
