Results A four-item automaticity subscale ( the ‘ Self-Report Behavioural Automaticity Index ’ ; ‘ SRBAI ’ ) was found to be reliable and sensitive to two hypothesised effects of habit on behaviour : a habit-behaviour correlation , and a moderating effect of habit on the intention-behaviour relationship .
Conclusion The SRBAI offers a parsimonious measure that adequately captures habitual behaviour patterns .
The SRBAI may be of particular utility in predicting future behaviour and in studies tracking habit formation or disruption
Background The twelve-item Self-Report Habit Index ( SRHI ) is the most popular measure of energy-balance related habits .
This measure characterises habit by automatic activation , behavioural frequency , and relevance to self-identity .
Previous empirical research suggests that the SRHI may be abbreviated with no losses in reliability or predictive utility .
Drawing on recent theorising suggesting that automaticity is the ‘ active ingredient ’ of habit-behaviour relationships , we tested whether an automaticity-specific SRHI subscale could capture habit-based behaviour patterns in self-report data .
When Planning is Not Enough: The Self-Regulatory Effect of Implementation Intentions on Changing Snacking Habits
Objective : This study examined whether matching implementation intentions to people ’s  regulatory orientation affects the effectiveness of changing unhealthy snacking habits .  Design : Participants ’ regulatory orientation  was either measured ( as a chronic trait ) or manipulated ( as a situational state ) , and participants were r and omly assigned to implementation intention conditions to eat more healthy snacks or avoid eating unhealthy ones . Main outcome measures : A self-reported online food diary of healthy and unhealthy snacks over a two-day period . Results : Participants with weak unhealthy snacking habits consumed more healthy snacks when forming implementation intentions ( regardless of match or mismatch with their regulatory orientation ) , while participants with strong unhealthy snacking habits consumed more healthy snacks only when forming implementation intentions that matched their regulatory orientations . Conclusion : Results suggest that implementation intentions that match regulatory orientation heighten motivation intensity and put snacking under intentional control for people with strong unhealthy snacking habits
