In western countries, smoking prevalence rates are high among smokers unmotivated to quit and those with a lower socioeconomic status (LSES). Multiple computer tailoring and the use of audio-visual aids may improve such interventions and increase cessation in LSES smokers. This study assessed the 12-month effectiveness of a video- and text-based computer-tailored intervention.
A randomized controlled trial in the Netherlands was used in which smokers were allocated to the video-based condition (VC) (N=670), the text-based condition (TC) (N=708) or the control condition (CC) (brief generic text advice) (N=721). After 12months, self-reported prolonged abstinence was assessed and biochemically verified in respondents indicating to have quit smoking. Three analysis strategies were used to assess the effects: (1) multiple imputation (MI); (2) intention-to-treat (ITT); (3) complete case analysis (CC).
VC was more effective in prolonged abstinence compared to CC (odds ratio (OR)=1.90, p=.005) and the text-based condition (OR=1.71, p=.01). VC was furthermore more effective than TC. No differences were found for SES and motivational levels. Results were similar when using ITT and CC. For our secondary outcome seven-day point prevalence abstinence; however, neither VC (OR=1.17, p=.34) or TC (OR=0.91, p=.52) outperformed the CC.
The video-based computer-tailored intervention was effective in obtaining substantial long-term abstinence compared to the text-based version and a brief generic text advice.
在西方国家，不愿戒烟的吸烟者以及社会经济地位较低者的吸烟率较高。多种计算机定制方式以及使用视听辅助工具可能会改善此类干预措施，并提高社会经济地位较低的吸烟者的戒烟率。本研究评估了基于视频和文本的计算机定制干预措施的12个月效果。
在荷兰进行了一项随机对照试验，将吸烟者分为视频组（VC）（N = 670）、文本组（TC）（N = 708）或对照组（CC）（简短的一般性文本建议）（N = 721）。12个月后，对报告已戒烟的受访者进行自我报告的长期戒烟情况评估，并进行生化验证。使用三种分析策略来评估效果：（1）多重插补（MI）；（2）意向性分析（ITT）；（3）完整病例分析（CC）。
与CC相比，VC在长期戒烟方面更有效（优势比（OR）= 1.90，p = 0.005），与文本组相比也更有效（OR = 1.71，p = 0.01）。此外，VC比TC更有效。在社会经济地位和动机水平方面未发现差异。使用ITT和CC时结果相似。对于我们的次要结局，即7天点患病率戒烟；然而，VC（OR = 1.17，p = 0.34）或TC（OR = 0.91，p = 0.52）均未优于CC。
与基于文本的版本和简短的一般性文本建议相比，基于视频的计算机定制干预措施在实现长期大量戒烟方面是有效的。
