Title: Random-Effect Models for Smoking Cessation with Change Patterns

Abstract:

The TransTheoretical Model (TTM) has played an important role in the area of behavior change in the past 20 years. Stages of change of problem behavior are promoted through intervening on temptation, decisional balance (DB), and (experiential and behavioral) processes of change (POC). All subjects were divided in to groups of stable nonchanger (SN), stable changer (SC), and relapser and recycler (RR) according to stages. Random effect model was applied to model the relationship between Temptation/DB/POCs and time, intervention group and change patterns. There were 16.0% SCs, 76.9% SNs, and 7.1% RRs in control group, while 18.3%, 75.3% and 6.4% in intervention group, respectively. Compared with control group, temptation and DB of intervention group were about 0.1-0.2 SD less; the intervention increased both experiential and behavioral POC of SCs and SNs, while decreased those of RRs. In both groups, RR's experiential and behavioral POC were higher than those of SC and SN across time, which suggests the nonlinear relationship between stages of change and POCs. At last, the impact of missing data was briefly discussed.
