Traditionally smoking cessation studies use smoker and nonsmoker categories almost exclusively to represent individuals quitting smoking. This study tested the transtheoretical model of change that posits a series stages through which smokers move as they successfully habit. Subjects in precontemplation (n = 166), contemplation 794), preparation 506) were compared on history, 10 processes change, pretest self-efficacy, decisional balance, well 1-month 6-month activity. Results strongly...
Subjects (A' = 970) representing five stages of smoking cessation (precontemplation, contemplation,action, maintenance, and relapse) were given a 65-item test measuring 10 basic processes change.Subjects recorded the last time they quit smoking, their current use, frequency occurrence,and degree item helpfulness. A 40-item questionnaire provided highly reliable measures 10processes change, labeled (a)consciousness raising, (b) dramatic relief, (c) self-liberation, (d)socialliberation, (e)...
The Decisional Balance Sheet of Incentives has been proposed by Janis and Mann (1977) as a general schema for representing both the cognitive motivational aspects human decision making. In this study, brief 24-item paper pencil measure was constructed to study decision-making process in smoking cessation. Two scales were identified labeled Pros Smoking Cons Smoking. These successful differentiating between five groups stages change quitting process. two also when employed predictors status...
Smokers (N = 756) were randomly assigned by stage of change to (a) standardized self-help manuals (ALA+ condition), (b) individualized matched (TTT (c) interactive expert-system computer reports plus (ITT or (d) a personalized condition with 4 counselor calls, manuals, and (PITT condition). Over 18 months, the ITT group's results more than doubled those ALA+ group on abstinence measures. The TTT conditions equivalent over 12 but at months was effective. best comparable treatment all...

Should one do a component analysis or factor analysis? The choice is not obvious, because the two broad classes of procedures serve similar purpose, and share many important mathematical characteristics. Despite textbooks describing common as preferred procedure, principal has been most widely applied. Here we summarize relevant information for prospective factor/component analyst. First, discuss key algebraic similarities differences. Next, analyze number theoretical practical issues. more...
The stages of change have already been well established with nonclinical populations. present study was designed to cross–validate the Stages Change Scales using a new clinical sample (N = 327). principal component, internal consistency, and cluster profile analyses demonstrated replica
The performance of four rules for determining the number components to retain (Kaiser's eigenvalue greater than unity, Cattell's SCREE, Bartlett's test, and Velicer's MAP) was investigated across systematically varied factors (sample size, variables, components, component saturation). Ten sample correlation matrices were generated from each 48 known population representing combinations conditions. SCREE MAP generally best all situations. test adequate except when variables close size....
