Section 1

Question Answer
Webb 2006: overviewThe present meta-analysis provides the first estimate of the overall impact of changing behavioral intentions on subsequent behavior change in experiments to date. An integration of 47 tests showed that a medium-to-large sized change in intention engenders only a small-to-medium change in behavior.
Webb 2006: resultsFindings also showed that intentions have less impact on behavior when participants lack control over the behavior, when there is potential for social reaction, and when circumstances of the performance are conducive to habit formation. Thus, this review suggests that intentional control of behavior is a great deal more limited than previous meta-analyses of correlational studies have indicated.
Webb 2006: futureFuture behavior change interventions should aim not only to identify more effective methods of changing intentions but also to facilitate the translation of intentions into action by promoting intention stability and implementation intention formation. The present findings also suggest, however, that future behavior change efforts might do well to give greater consideration to nonintentional routes to action such as prototype perceptions (e.g., Gibbons et al., 2003) and automotives

Section 2

Question Answer
Hill 2007: overviewRCT evaluate the effectiveness of a theory based persuasive leaflet, for students to take up at least one additional PA session/week. 503 secondary school students.
Hill 2007: leafletbased on TPB - 1. raise awareness of exercise types 2. promote positive attitudes 3. target normative beliefs 4. enhance behavioural control. 5. prompt exercise intentions.
Hill 2007: groups leaflet, leaflet and implementation intentions prompt, and control.
Hill 2007: results The results showed that all three-leaflet interventions significantly increased reported exercise, intention to exercise and related cognitions, compared to the control condition, but did not differ in their impact. Mediation analysis showed that intervention effects on exercise were partially mediated by intentions and perceived behavioural control
Hill 2007: limitationsself-report measures, which was brief. no longer term follow up.
Hill 2007: summarycost-effective leaflet, good for promoting exercise in youth settings. formative research is needed to elicit admired sports personalities and other issues related to the persuasiveness of messages (Elaboration Likelihood model)
