“…action self-efficacy), when compared with intenders and actors, are in line with both the theoretical expectations derived from 75 the HAPA model and results of previous studies showing that self-efficacy is one of the factors most strongly and consistently associated with actual FV intake [32]. Considering that self-efficacy may be promoted by verbal persuasion [33] and that 80 interventions in self-efficacy beliefs have proven to be successful in increasing FV intake [28], enhancing individuals' action self-efficacy towards FV consumption should also be a goal of health communications targeting non-intenders.…”

Theoretically driven health communications are needed to promote fruit and vegetable intake among people at different stages of change. The Health Action Process Approach, a clearly speci-15 fied model and good predictor of fruit and vegetable intake, was used as a framework to guide a formative research for the development of health messages targeting individuals at either a nonintentional or intentional stage of change. A 20 mixed-method approach was used, combining eight focus groups (n ¼ 45) and a questionnaire (n ¼ 390). Target beliefs for people at both stages were identified under five theoretical constructs (risk perception, outcome expectancies, action 25 planning, coping planning and self-efficacy). Highlighting health problems due to low fruit and vegetable consumption, health benefits, weight reduction and pleasure and enhancing self-efficacy to increase fruit and vegetable 30 intake are the main guidelines for designing messages to non-intenders. For intenders, messages should reassure them of their ability to maintain adequate fruit and vegetable consumption, outline specific plans for increased consumption, 35identify barriers such as preparation, forgetting or being tired and unwilling to eat fruits and vegetables and suggest strategies to overcome them, such as presenting some practical examples on how to include fruits and vegetables 40 when eating out.

“…wet hands, lather for at least 10 seconds, rinse and dry thoroughly). As well, interventions using implementation intentions have usually targeted a group that intended to change their behaviour (Luszczynska, Tryburcy, et al, 2007). Across all groups there was a high baseline percentage (48.7%) of participants indicating that they prepared food hygienically every time they cooked a meal, and on average participants reported that 17 they were preparing food hygienically 80% of the time in the previous week.…”

“…There is evidence that an individual's self-efficacy beliefs are positively related to the goals they set and their commitment to engage in the intended behaviour, even if failure occurs (Schwarzer, 1992). An intervention that targeted self-efficacy in increasing fruit and vegetable consumption showed that the group which increased self-efficacy alone benefited equally from the intervention compared to the group that also made plans to increase behaviour (Luszczynska, Tryburcy, & Schwarzer, 2007). Change in self-efficacy was able to predict change in behaviour at a 6 month follow-up, which indicates that enhancing perceptions of control may result in long term behaviour change.…”

Using the Theory of Planned Behaviour to design a food hygiene intervention

Twenty percent of food poisoning annually in Australia is believed to result from consumer food handling behaviour. Research advocates the use of social cognition theories in designing food hygiene interventions, however very few studies have actually done so. Thus, this study investigated the efficacy of a food hygiene intervention based on the Theory of Planned Behaviour (TPB). One hundred and eighty-four participants completed a TPB questionnaire, including questions regarding past behaviour and food hygiene knowledge, and then were randomly allocated to a knowledge and implementation intention group, a combined knowledge/implementation intention/PBC group, or a control group. Behaviour was measured four weeks later. The TPB predicted a high proportion of variance in both intentions and behaviour, but neither intervention improved participants' food hygiene behaviours. However, knowledge and PBC were significantly increased in the PBC group. The implications of this for future research are explored.

The objective of this study was to assess changes in adolescent girls' health-enhancing cognitions and behaviors targeted by the Go Girls! group-based mentorship lifestyle program. Three hundred and ten adolescent girls (nested within 40 Go Girls! groups) completed questionnaires that assessed cognitions (attitudes, self-regulatory efficacy, and intentions) and behaviors (physical activity and dietary) at four time points (two pre-program, one at the end of the program, and one at 7-week follow-up [5]. In response to these public health concerns, genderspecific lifestyle interventions have been developed for adolescent girls that target health behaviors, such as physical activity and dietary behaviors, and cognitions toward those behaviors.The majority of gender-specific lifestyle interventions for youth have tended to focus on the prevention or treatment of obesity [e.g., 6, 7]. For example, Neumark-Sztainer and colleagues [8] examined the effectiveness of a physical education program entitled "New Moves" to target health behaviors and body image among adolescent girls at risk of overweight and obesity. Results from this study [8] indicate that after completing the program, girls reported significant improvements in portion control, reductions in sedentary behavior, and increases in their physical activity self-efficacy and self-reported psychological "stage of change" for both dietary and physical activity behaviors. However, no significant changes were found for physical activity behavior or quality of dietary intake in terms of consumption of fruit and vegetables and sugar-sweetened beverages. Similarly, findings from another school-based lifestyle program for adolescent girls indicated improvements in girls' health behavior intentions and dietary knowledge, but no changes in physical activity or dietary behavior after completing the program [9].In light of the limited effectiveness of these programs, theory-based research is needed to target behavior change. Specifically, the social context has
