In a previous paper (1928) the senior author stated that addiction to purified alkaloids of opium was a rare occurrence in India. In western countries morphine and of late years codeine and heroin also have been extensivelyused. In view of the fact that habitual use of alkaloids, such as cocaine, is being gradually introduced into India from these countries and from the Far East, the Drug Addic...

BACKGROUND Despite strong support for predictive validity of the theory of planned behavior (TPB) substantial variance in both intention and behavior is unaccounted for by the model's predictors. The present study tested the extent to which habit strength augments the predictive validity of the TPB in relation to a currently under-researched behavior that has important health implications, name...

Wepropose a utility-theoretic brand-choice model that accounts for four different sources of state dependence: 1. effects of lagged choices (structural state dependence), 2. effects of serially correlated error terms in the random utility function (habit persistence type 1), 3. effects of serial correlations between utility-maximizing alternatives on successive purchase occasions of a household...

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 t...
