The authors tested whether adherence to simultaneous health behavior changes was unitary or domain specific among 76 women who modified smoking, eating, and physical activity to accomplish smoking cessation plus weight control. Random-effects regression analyses showed that adherence to both smoking and diet plans declined linearly and covaried positively; their association tended to grow stronger over time. In contrast, physical activity plan adherence did not change over time and was unrelated to other domains. At the end of treatment, 65%, 30.5%, and 25% adhered well or excellently to smoking, diet, and activity treatments, respectively. Findings support both unitary and domain-specific aspects of adherence and suggest that among smokers, smoking and eating behaviors may have similarities unshared by physical activity. 相似文献

An experimental components analysis of brief HIV risk-reduction counseling based on the information-motivation-behavioral skills (IMB) model was conducted with 432 men and 193 women receiving sexually transmitted infection (STI) clinic services. Following baseline assessments, participants were randomly assigned to 1 of 4 90-min risk-reduction counseling sessions that deconstructed the IMB model within a full factorial design. Participants were followed for 9 months, with STI diagnoses monitored over 12 months. Men who received the full IMB session evidenced relatively greater use of risk-reduction behavioral skills and relatively lower rates of unprotected intercourse over 6-months follow-up and had fewer new STIs. For women, however, the motivational counseling demonstrated the most positive outcomes. Results suggest that brief single-exposure HIV prevention counseling can reduce HIV transmission risks. 相似文献

Nonsuicidal self‐injury (NSSI) prior to age 18 was evaluated as a risk factor for adulthood suicide attempt (SA). Archival data from 222 mood‐disordered participants were analyzed using multivariate Cox proportional hazards analysis. Participants with a youth SA were excluded. The hazards of SA among adult participants with a history of youth NSSI were twice than those of mood‐disordered participants without youth NSSI (hazard ratio = 2.00, 95% confidence interval = 1.16–3.44, p = .01). Moreover, participants who had both youth and adult NSSI attempted suicide significantly earlier than participants who began NSSI as an adult. Youth NSSI is associated with persistent, elevated SA risk in adulthood. 相似文献
