...The TPB seems to be most predictive amongst the young, fit and affluent and when predicting selfreported behaviour over a short term (McEachan et al., 2011; Sniehotta et al., 2013), which is less compatible with populations in which behaviour change theory is most needed....
[...]
...We have also learned that intention and PBC are quite consistent psychological predictors of behaviour (McEachan et al., 2011) and that interventions resulting in large changes in intention are likely to also change behaviour (Webb & Sheeran, 2006)....
[...]
...Moreover, the static explanatory nature of the TPB does not help to understand the evidenced effects of behaviour on cognitions and future behaviour (McEachan et al., 2011; Sutton, 1994)....

...First, many of them include both cross-sectional and prospective measures of behaviour (Ajzen, 1991; Godin & Kok, 1996; Hagger et al., 2002; Hausenblas et al., 1997; Notani, 1998; Sheeran, Abraham, & Orbell, 1999; Sheppard, Hartwick, & Warshaw, 1988; Trafimow et al., 2002; van den Putte, 1993)....

...Overall, the TPB has been shown to be an adequate predictor of intention and behaviour explaining 40 49% of the variance in intention and 26 36% of the variance in behaviour (Ajzen, 1991; Armitage & Conner, 2001; Godin & Kok, 1996;...

...…to be a limiting condition of the TPB (i.e., TPB variables should only predict behaviour to the extent that they remain stable between the point at which they are measured and the point at which the behaviour occurs and this should be less likely as the time interval increases; Ajzen, 1985, 1991)....

...Although the explained variances might suggest the value of examining addition predictors of behaviour within the TPB (Ajzen, 1991), the present data would suggest this to be particularly the case in relation to these latter behaviours....

...The Theory of Planned Behaviour (TPB: Ajzen, 1988, 1991; an extension of the earlier Theory of Reasoned Action, TRA: Ajzen & Fishbein, 1980) has been one of the most widely tested models of the factors influencing health-related behaviour....

...However, the prediction of intention from TPB variables was similar to levels identified by past reviews of between 42% and 45% variance explained (Armitage & Conner, 2001; Hagger et al., 2002; Rivis & Sheeran, 2003a; Schulze & Whittmann, 2003; Sheeran & Taylor, 1999; Trafimow et al., 2002)....

...Indeed, the attitude intention correlation (0.57 vs. 0.49), the SN intention (0.40 vs. 0.34) and the PBC intention correlation (0.54 vs. 0.43) were stronger in the present study compared to Armitage and Conner (2001)....

...The TPB is a parsimonious model that has been applied to a wide range of behaviours (for reviews see Albarracin, Johnson, Fishbein, & Muellerleile, 2001; Albarracin, Kumkale, & Johnson, 2004; Armitage & Conner, 2001; Cooke & French, 2008; *Corresponding author....

...Previous work has noted that SN are the weakest predictor in the TPB (e.g., Armitage & Conner, 2001; Godin, Savard, Kok, Fortin, & Boyer, 1996; Hagger et al., 2002; Hausenblas et al., 1997)....

...In relation to measures of behaviour, current evidence exists to suggest that self-report measures of behaviour are better explained than objective measures of behaviour (Armitage & Conner, 2001)....
