Intention is theorized as the proximal determinant of behavior in some theories of motivation, but the need to understand predictors of action control (i.e., translating an intention into behavior) is warranted to tailor physical activity intervention efforts. The purpose of this study was to examine constructs of the transtheoretical model of behavior change (TTM) as predictors of physical activity intention-behavior profiles across 6 months in a large Canadian sample (N = 1,192). Results showed that 5 of the 8 possible intention-behavior profiles had a substantial number of participants: nonintenders, unsuccessful adopters, successful adopters, unsuccessful maintainers, and successful maintainers. Constructs of the TTM distinguished (p < .01) intention-behavior profiles. Self-efficacy and the behavioral processes of change were particularly good predictors of action control (p < .01), but disaggregated beliefs and processes identified specific intervention targets for successful physical activity adoption and maintenance. The results validate that both action planning and action control are important when understanding physical activity behavior. 相似文献

CAUCASIAN LESBIANS' USE OF PSYCHOTHERAPY: A Matter of Attitude? 总被引:1,自引:0,他引:1
Kris S. Morgan 《Psychology of women quarterly》1992,16(1):127-130
Evidence suggests that a high proportion of lesbians seek psychological counseling. This study represents an empirical investigation of the disproportionate use of mental health services by lesbians, focusing on the hypothesis that lesbians place a greater value on psychotherapy than do nonlesbian women. Participants (100 lesbians and 309 nonlesbian women, 97% Caucasian) completed Surgenor's revision of the Attitudes Toward Seeking Professional Psychological Help Scale. Results indicate that the lesbian group had a significantly more positive attitude toward seeking psychological counseling than did the nonlesbian sample, regardless of whether or not they had experienced psychological counseling. 相似文献

The Sentencing Reform Act of 1984, which created the U.S. Sentencing Commission, required that the commisson consider prison capacity in drafting sentencing guidelines. As part of the commission's efforts to meet this requirement, we developed a computer simulation capable of projecting the impact of the commission's guidelines on future sentences and prison populations. According to our projections, “straight” probation sentences will be reduced significantly under the guidelines. However, reducing the use of probation will generate only modest demands on the prisons, and then mostly for community corrections phased in over the course of 5 years. We also project that, while average time served for violent offenses will increase substantially, average time served for most property crimes will remain largely the same. Finally, while we forecast that federal prison populations will grow markedly by the end of this century, this is more a result of the Anti-Drug Abuse Act of 1986 and the career offender provision of the Comprehensive Crime Control Act of 1984 than a result of the guidelines. 相似文献

Mentor relationships and the career development of pregnant and parenting African-American teenagers 总被引:2,自引:0,他引:2
The influence of natural mentor relationships on the career outlook of African-American pregnant and parenting teenagers was examined. More than half of the participants nominated adults they considered to be mentors. A path model indicated that mentor support was associated with increased life optimism, beyond its indirect effects on career activities and beliefs about the opportunity structure. These findings suggest that natural mentors are an important resource in the career developmnent of pregnant and parenting African-American adolescents. 相似文献
