Two theoretical approaches to smoking cessation were compared. Participants were randomly assigned either to (a) a traditional treatment program that used contingency contracting and that emphasized the necessity for absolute abstinence (AA) or to (b) a relapse-prevention (RP) treatment that focused on gradual acquisition of nonsmoking skills. It was hypothesized that participants in the RP treatment would be less successful initially but would have better maintenance skills and thus would relapse less during a 1-year follow-up period. Each program was evaluated in two formats: group-based treatment and self-help materials. Results indicated comparable 1-year abstinence rates for all treatments, although more participants dropped out of the self-help formats. Participants in the RP intervention were more likely to lapse sooner after quitting and were more likely to quit again during the 1-year maintenance period. Exploratory analyses of successful participants suggested that women were more successful in the RP program and that men had greater success with the AA approach.  相似文献

Love and Lust Revisited: intentionality, homosexuality and moral education   总被引:1,自引:0,他引:1  
ABSTRACT In his book Sexual Desire , Roger Scruton wrongly maintains that human sexual experience is essentially intentional. His thesis depends on his highly revisionary definitions of 'sexual arousal' and 'sexual desire', the artificial nature of which I expose and criticise.
He admits that homosexual desire is capable of the same kind of intentionality as heterosexual desire, and is therefore not intrinsically obscene or perverted, but he advances reasons why homosexuality is morally different from heterosexuality and is therefore an object of disapproval. His arguments presuppose 'an impassable moral divide' between the sexes and are, on his own admission, not very cogent.
Since he allows that homosexual desire is a natural and spontaneous phenomenon and also proposes that moral education should guide us towards a state in which our sexuality is entirely integrated within a life of personal affection and responsibility, consistency requires that he adopt a sexual ideology which does not discriminate against homosexuality. For homosexuals are unlikely to achieve the 'sexual integrity' which Scruton advocates (and which I endorse) if they are constantly encouraged to disparage their own sexual nature and if social institutions make no positive provision for them.  相似文献
