This longitudinal study investigates the relation between recall memory and communication in infancy and later cognitive development. Twenty-six typically developing Swedish children were tested during infancy for deferred imitation (memory), joint attention (JA), and requesting (nonverbal communication); they also were tested during childhood for language and cognitive competence. Results showed that infants with low performance on both deferred imitation at 9 months and joint attention at 14 months obtained a significantly lower score on a test of cognitive abilities at 4 years of age. This long-term prediction from preverbal infancy to childhood cognition is of interest both to developmental theory and to practice.  相似文献

The prevalence of older adolescents' positive attitudes toward younger sexual partners was investigated through three measures of self-reported hypothetical likelihood of having sex with preadolescents and younger adolescents (LSA), using a school-based cluster sample of 710 Norwegian 18- to 19-year-olds attending nonvocational high schools in Oslo. Some likelihood of having sex with a preadolescent (less than 12 years of age) was reported by 5.9% of the males. The 19.1% of the males who indicated some likelihood of having sex with a 13- to 14-year old, compared to those who did not, reported more high-frequency drinking, more alcohol-related problems, earlier sexual initiation, more conduct problems, and poorer psychosocial adjustment. This subgroup also reported more high-frequency use of pornography, having more friends with an interest in child pornography and violent pornography, and greater use of coercion to obtain sexual favors.  相似文献

Clinical significance methods: a comparison of statistical techniques   总被引:6,自引:0,他引:6  
Clinically significant change refers to meaningful change in individual patient functioning during psychotherapy. Following the operational definition of clinically significant change offered by Jacobson, Follette, and Revenstorf (1984), several alternatives have been proposed because they were thought to be either more accurate or more sensitive to detecting meaningful change. In this study, we compared five methods using a sample of 386 outpatients who underwent treatment in routine clinical practice. Differences were found between methods, suggesting that the statistical method used to calculate clinical significance has an effect on estimates of meaningful change. The Jacobson method (Jacobson & Truax, 1991) provided a moderate estimate of treatment effects and was recommended for use in outcome studies and research on clinically significant change, but future research is needed to validate this statistical method.  相似文献

The aim of this multicenter study was to explore associations between psychosocial factors (general self-efficacy, perceived availability of social support, cancer-related distress) and health-related quality of life, among individuals at risk for hereditary cancer. One-hundred and twenty one participants with a family history of breast-cancer or colorectal cancer answered a questionnaire 2-4 weeks prior to genetic counseling. The two dimensions of the health-related quality of life measure, mental and physical health were both used as outcome variables. Multiple regression (linear) analyses revealed that increasing degrees of cancer-related distress was related to decreasing degrees of mental health whereas increasing degrees of self-efficacy and social support were related to increasing degrees of this outcome variable. Self-efficacy, self-esteem support and tangible aid seemed to moderate the relationship between cancer-related distress and mental health. These results suggest that self-efficacy and certain resources of social support buffer the negative association between cancer-related distress and mental health, and might be suitable for interventional efforts. Implications for genetic counseling practice are discussed.  相似文献

Sex differences in episodic memory: minimal influence of estradiol   总被引:4,自引:0,他引:4  
Sex differences exist for several cognitive tasks and estrogen has been suggested to influence these differences. Eighteen men and 18 women were matched on age and estradiol level. Potential sex differences were assessed in episodic memory, semantic memory, verbal fluency, problem solving, and visuospatial ability. Significant sex differences, favoring women, were found for tasks assessing episodic memory. Correlations between estradiol level and cognitive performance were significant for face recognition in females. Since sex differences remained in verbal episodic memory tasks and face recognition despite matched levels of estradiol, circulating estradiol does not appear to be of paramount consequence for observed sex differences in episodic memory.  相似文献

An instrument measuring attitudes toward suicide was developed through two postal questionnaire surveys, 1986 and 1996, approaching general population samples of 700 and 1,000 persons, respectively, and with response rates of 75% and 64%. A 10-factor model was obtained and comparisons between waves revealed an overall more permissive and pro-preventional attitude in 1996. The results implied complex relationships at the aggregated level between attitudes and suicidal behavior, depending on type of suicidal behavior, attitude factor, and subgroup. At the individual level, persons answering affirmative on own suicidal behavior, as compared to the nonsuicidal group, held a more permissive and understanding attitude toward suicide.  相似文献

This study investigated the effects of an internet-based self-help stress management program with a randomized controlled design. Of 85 participants, 26% dropped out, leaving a final sample of 63 participants with 23 in the treatment group and 40 in the waiting list control group. Treatment included applied relaxation, problem solving, time management and cognitive restructuring. All information and treatment interventions were provided via the internet. Results were evaluated with the Perceived Stress Scale and the Hospital Anxiety and Depression Scale. Improvements were seen in both groups, with greater improvements in the self-help treatment group. It is concluded that the internet can be used to provide stress management techniques and result in stress relief. However, spontaneous improvement, differential dropout rate and compliance need to be monitored in future studies.  相似文献
