Latent transition analysis to the stages of change for smoking cessation

Article Abstract:

A study applying Latent Transition Analysis (LTA) to assess the movement through the stages of change for smoking cessation indicates that the method of data analysis can be suitable for testing of alternate models of movement. LTA allows comparison of alternative theoretical models by depicting the pattern of change. It shows that the movement through the stages is not linear. The assessment of latent status membership on each occasion and transition probabilities between occasions is possible. It also helps in diagnosing the stability of individual stage membership.

Current issues in behavioral and pharmacological approaches to smoking cessation

Article Abstract:

Research in behavioral treatments (BTs) has not been getting the attention it deserves, while research in nicotine replacement treatments has been active. The apparently unfavorable record of BTs is attributed to a host of factors. These include the facts that BTs have not been sufficiently evaluated and that methodological problems plague BT research. Logistical setbacks such as cost, large samples, long follow-ups and biochemical validation also hamper research efforts. Overall success rates also remain low, even with NRT as complement treatment.

Levels of cotinine associated with long-term ad-libitum nicotine polacrilex use in a clinical trial

Article Abstract:

The magnitude of nicotine replacement among previous smokers was examined among the special intervention group in the Lung Health Study by measuring the ad-libitum levels of nicotine polacrilex gum (NG) usage over a span of five-years of free access. Approximately two-thirds of the subjects initially quit smoking using NG during the first four months. The results revealed that successful quitters used an average of eight NG per day and that those using NG while still smoking consumed an average of six to seven pieces per day.
