Stages and processes of self-change of smoking: Toward an integrative model of change.
An integrative model of change was applied to the study of 872 Ss (mean age 40 yrs) who were changing their smoking habits on their own. Ss represented the following 5 stages of change: precontemplation, contemplation, action, maintenance, and relapse. 10 processes of change were expected to receive differential emphases during particular stages of change. Results indicate that Ss (a) used the fewest processes of change during precontemplation; (b) emphasized consciousness raising during the contemplation stage; (c) emphasized self-reevaluation in both contemplation and action stages; (d) emphasized self-liberation, a helping relationship, and reinforcement management during the action stage; and (e) used counterconditioning and stimulus control the most in both action and maintenance stages. Relapsers responded as a combination of contemplaters and people in action would. Results are discussed in terms of developing a model of self-change of smoking and enhancing a more integrative general model of change.

The Transtheoretical Model of Health Behavior Change
The transtheoretical model posits that health behavior change involves progress through six stages of change: precontemplation, contemplation, preparation, action, maintenance, and termination. Ten processes of change have been identified for producing progress along with decisional balance, self-efficacy, and temptations. Basic research has generated a rule of thumb for at-risk populations: 40% in precontemplation, 40% in contemplation, and 20% in preparation. Across 12 health behaviors, consistent patterns have been found between the pros and cons of changing and the stages of change. Applied research has demonstrated dramatic improvements in recruitment, retention, and progress using stage-matched interventions and proactive recruitment procedures. The most promising outcomes to data have been found with computer-based individualized and interactive interventions. The most promising enhancement to the computer-based programs are personalized counselors. One of the most striking results to date for stage-matched programs is the similarity between participants reactively recruited who reached us for help and those proactively recruited who we reached out to help. If results with stage-matched interventions continue to be replicated, health promotion programs will be able to produce unprecedented impacts on entire at-risk populations.

A conceptual map of invasion biology: Integrating hypotheses into a consensus network
Abstract Background and aims Since its emergence in the mid‐20th century, invasion biology has matured into a productive research field addressing questions of fundamental and applied importance. Not only has the number of empirical studies increased through time, but also has the number of competing, overlapping and, in some cases, contradictory hypotheses about biological invasions. To make these contradictions and redundancies explicit, and to gain insight into the field’s current theoretical structure, we developed and applied a Delphi approach to create a consensus network of 39 existing invasion hypotheses. Results The resulting network was analysed with a link‐clustering algorithm that revealed five concept clusters (resource availability, biotic interaction, propagule, trait and Darwin’s clusters) representing complementary areas in the theory of invasion biology. The network also displays hypotheses that link two or more clusters, called connecting hypotheses , which are important in determining network structure. The network indicates hypotheses that are logically linked either positively (77 connections of support) or negatively (that is, they contradict each other; 6 connections). Significance The network visually synthesizes how invasion biology’s predominant hypotheses are conceptually related to each other, and thus, reveals an emergent structure – a conceptual map – that can serve as a navigation tool for scholars, practitioners and students, both inside and outside of the field of invasion biology, and guide the development of a more coherent foundation of theory. Additionally, the outlined approach can be more widely applied to create a conceptual map for the larger fields of ecology and biogeography.
