A survey of South African secondary school students aged 12–17 years (n = 893) included measures designed to investigate relationships between beliefs about HIV/AIDS, condom use, interpersonal relationships, and two dependent measures: motivation to use condoms and reported condom use. We predicted that motivation would be an important correlate of reported condom use and that traditional cultural beliefs included in social cognition models would predict condom use motivation. Hierarchical multiple regression showed that 10% of the variance in reported condom use was accounted for by condom use motivation and age. Condom self‐efficacy, beliefs about condoms and injunctive norms accounted for much of the variance. Other beliefs included susceptibility to HIV and attribution of HIV to asexual sources such as witchcraft indicating that an expanded model of modifiable cognitions may be optimal when designing HIV interventions among young South Africans.  相似文献

In a cross-sectional study of 164 participants aged 21 to 91, the authors examined age differences on two implicit tests, fragmented object identification (FOI) and category exemplar generation (CEG), and on tests of explicit memory, attention, and verbal fluency. FOI results revealed impaired perceptual skill learning in those over 60 and a decrease in perceptual priming across young, middle-aged, and older groups. CEG priming was impaired in those over 80. Regression analysis revealed explicit contamination of priming on both the FOI and CEG tests. Across the three implicit measures, age accounted for 4 to 13% of the variance when explicit memory was controlled. Semantic fluency predicted CEG priming, suggesting possible frontal lobe involvement on the test. Altogether, results indicate that age has a small but reliable influence on implicit memory.  相似文献

In a study of the developmental significance of certain perceptual activities, the Rorschach and four structured tests of perception were administered to five groups of children at various CA, MA, and IQ levels. All three Rorschach measures were significantly related to MA, as were all four of the structured tests. The Childrens' Embedded Figures Test was the best predictor of MA; it accounted for 52% of the variance, while the six remaining measures yielded nonsignificant increments to a multiple regression equation. In a factor analysis the four structured tests loaded on one factor (51% of total variance), while the three Rorschach variables loaded on a second (17%); MA loaded on both (.669 and .447, respectively). In an additional finding, Zigler's “developmental” hypothesis that level of development and not IQ determines cognitive competence, received partial support from 13 of 14 statistical tests.  相似文献

Prison inmates have high prevalence rates for both HIV and AIDS, creating a great need for HIV prevention efforts. We tested the theory of planned behavior (TPB) in 3 domains: intention to engage in condom use when released, intention to not share tattoo equipment in prison, and intention to not share needles or tattoo equipment when released. A total of 478 inmates (87% male) completed TPB and sexual and needle‐use risk behavior measures. TPB constructs accounted for a significant variance in intention to use condoms among African American, Hispanic, and Caucasian inmates, though the strength of the relationships differed by ethnicity. The TPB was less successful for intention to share tattooing equipment and not to share needles or tattoo equipment after release.  相似文献

The psychosocial determinants of health-impairing physical inactivity among Hispanic populations have not been well explored nor have systematic comparisons been made with White populations using Social Cognitive Theory (SCT) measures. Three exercise-relevant efficacy measures (task, scheduling, and response efficacy), three exercise-relevant expectancy measures (physical health, psychological health, and self-evaluative), and self reports of activity levels were obtained from 20-year-old male and female Hispanics (n?=?94) and Whites (n?=?94). Activity levels for the two groups were analyzed in separate regression analyses that included the six SCT measures and gender as predictors. The set of seven predictors accounted for 51% of the variance in self-reported activity levels in each analysis. For young adult Hispanics, task efficacy, response efficacy, mental-health expectancies, and self-evaluative expectancies predicted activity level. For young adult Whites, scheduling efficacy and self-evaluative expectancies predicted activity level. Gender was not a significant predictor of activity level for either group. A multivariate analysis of variance indicated that the only SCT predictor on which Hispanics and Whites significantly differed was mental-health expectancies. The results of this study indicate that the psychosocial determinants of exercise are qualitatively different for the two groups and that the determinants of physical activity levels for young adult Hispanics may not be as effective as those of young adult Whites in sustaining lifelong exercise habits. Thus the present study offers a promising strategy for detecting inactivity-related physical- and mental-health risks at an age when lifelong habits of physical activity are still being formed.  相似文献

Parental involvement in school-related tasks is associated with a number of positive outcomes across ethnic groups. However, a growing literature suggests that unique forms of involvement and barriers exist among linguistic minority Latino families. The Parental Schoolwork Support Measure-Youth (PSSM-Y) is introduced in this study along with the psychometric properties found with a sample of 133 Latino youth in Grades 5 through 7 from a public school in a low-income urban neighborhood. Exploratory factor analyses indicated the presence of three factors called direct support, language and support, and indirect support, which together accounted for 66.3% of the common variance in the 16-item version. Strong internal consistency and test-retest coefficients were found for the PSSM-Y in this sample. In addition, schoolwork support was correlated with youth depression, economic pressure, loneliness, and familism in the expected directions. The findings are discussed in terms of the potential utility of this measure for future school-based studies of Latino students and youth of immigrant backgrounds in the United States.  相似文献

The World Health Organization stressed that compliance with the use of safety helmet could significantly reduce the risk of injury by 72% and the probability of death by 39%. In Malaysia, the enforcement of the safety helmet legislation significantly reduced 30% of motorcycle crash fatalities in Malaysia. The aim of this study is to explore the use of motorcycle helmets and the determinants of standard helmet usage among child pillion riders. A cross-sectional survey of 200 adult riders accompanied by the child pillion riders aged 6–12 years old from Klang, Selangor, was conducted. The proper use of the helmet among the respondents and the child pillion riders was observed and recorded. A questionnaire was used to assess socio-demographic background and awareness of the use of child safety helmets. The data was analyzed using SPSS version 23. Only 3% of child pillion riders use standard child safety helmets, while 37% wear standard adult motorcycle helmets. Adult riders who were married, female, always wear helmets, have a higher household income and travel a long distance, are more likely to use a standard motorcycle helmet for their child pillion riders. Knowledge on Standard Certification (SIRIM) label and its importance, awareness of the campaign on child safety helmets, police enforcement, understanding the safety of toy/game helmet use have been identified as additional determinants of standard helmet use among child pillion riders. This study recommends prospective studies with continuous road safety educations programs that integrate behavioural change approaches to enhance the use of standard motorcycle helmets among the child pillion riders in Malaysia.  相似文献

Poythress, Edens, and Lilienfeld (1998) recently reported a moderately strong correlation between Hare's (1991) Psychopathy Checklist-Revised (PCL-R) and a newly developed self-report measure of psychopathy, the Psychopathic Personality Inventory (PPI) of Lilienfeld and Andrews (1996), in an ethnically diverse sample of 50 inmates from a youthful offender prison. The present study reports follow-up data regarding disciplinary infractions in this sample and examines the utility of the PCL-R and PPI for identifying those at risk for institutional misbehavior. Generally modest, but statistically significant, correlations were obtained between both measures and indices of aggressive institutional behavior. Multiple regression analyses revealed that both measures accounted for common variance in the criterion but that neither accounted for significant unique variance. Results are discussed in terms of the clinical utility of these measures in populations of young offenders.  相似文献

This study investigated the relations between various developmental factors and performance in remedial courses. The Iowa Developing Autonomy Inventory, Iowa Managing Emotions Inventory, and Iowa Developing Competency Inventory were administered to 231 students enrolled in a developmental studies program at a large state university (enrollment about 25,000). Regression analyses indicated that various developmental measures accounted for a small effect (amount of variance accounted for ranged from 2% to 7%) on performance in remedial courses. The percentage of variance accounted for by the three inventories was similar to what could be accounted for by more traditional measures of SAT scores and high-school grade point averages. The percentage of variance accounted for by traditional measures ranged from 2% to 10%.  相似文献

This study presents two sets of analyses designed to evaluate the relation between a 12-item form of the Washington University Sentence Completion Test of ego development (Short Form; SCT-S) and socioeconomic status (SES). The subjects were a large national random sample of adolescent and young adult men and women who were stratified into three artificial age cohorts. The first set of hierarchical multiple regression analyses indicated that SES accounted for 8% to 13% of the variance in SCT-S scores. Incremental validity of the SCT-S in predicting social attitudes, beyond that predicted by SES, was generally supported for authoritarian aggression and partially supported in predicting masculine sex role expectations. Findings suggest that research on ego development with subjects over age 18 might use level of education as a rough index of SES. For younger subjects, parental factors and education are both important. This study also provides revised age-specific national norms for the SCT-S.  相似文献

This study examined the relative contributions of parental reports of child-related and parent-related stress to their estimates of expressive and receptive language skills on the Minnesota Child Development Inventory in 152 children referred to a communicative disorders clinic. Correlational analysis showed moderately high agreement between parental estimates and objective measures of expressive and receptive language ability. Multiple-regression analyses revealed that independent measures of language acquisition accounted for the greatest amount of variance in parental estimates of expressive and receptive language skills. Stressful child behavior accounted for a small but statistically significant proportion of the variance in estimates of expressive and receptive language skills. Parental stress, in contrast, did not contribute significantly to language estimates. These findings suggest that parents are able to formulate estimates of language development which are relatively independent of personal or child-related stressors.  相似文献

OBJECTIVE: In Attention Deficit Hyperactivity Disorder (ADHD) agreement between parents and teachers is often low. Parental depressed mood and parenting stress are considered to decrease informant agreement. This study examined informant agreement in children with ADHD and the association between parental depressed mood, parenting stress and agreement in the ratings of ADHD, ODD and CD symptoms. METHOD: 65 parents completed questionnaires on ADHD behavior of their child, parenting stress and depressed mood, teachers reported on ADHD behavior. RESULTS: Low agreement was found for hyperactive and moderate agreement for inattentive, ODD and CD symptoms. Stepwise regression analyses showed that parenting stress, and not parental depressed mood accounted for 12% of the variance in inattention symptoms disagreement, 14% of the variance in hyperactive symptoms disagreement and 9% in oppositional behavior disagreement. No significant predictors were found for CD disagreement. The found effect was independent of stimulant medication use. CONCLUSION: Parenting stress, but not parental depressed mood, was associated with the disagreement between parents and teachers on both ADHD and ODD symptoms. These results emphasize the importance of considering parenting stress in diagnosing ADHD and comorbid ODD.  相似文献

This longitudinal study separated resource demand effects from those of retention interval in a counting span task among 100 children tested in grade 2 and again in grades 3 and 4. A last card large counting span condition had an equivalent memory load to a last card small, but the last card large required holding the count over a longer retention interval. In all three waves of assessment, the last card large condition was found to be less accurate than the last card small. A model predicting reading comprehension showed that age was a significant predictor when entered first accounting for 26% of the variance, but counting span accounted for a further 22% of the variance. Span at Wave 1 accounted for significant unique variance at Wave 2 and at Wave 3. Results were similar for math calculation with age accounting for 31% of the variance and counting span accounting for a further 34% of the variance. Span at Wave 1 explained unique variance in math at Wave 2 and at Wave 3.  相似文献

Unrestrained and unhelmeted occupants are at increased risk of severe injury or death in the event of a crash, and there is evidence that children, particularly in low and middle income countries, have low restraint and helmet wearing rates.Roadside observations of occupants of passing vehicles (7247 cars, vans and taxis and 2897 motorcycles) in nearside lanes were made at seven selected road sites located around the Klang Valley (greater Kuala Lumpur) area representing a variety of demographic locations.The findings revealed an overall low rate of seat-belt wearing in vehicles (front seat drivers: 44.6%; front seat adult passengers: 33.8%; front seat child passengers: 11.8%; rear seat adult passengers: 5.2%; and, rear seat child passengers: 5.8%). For motorcyclists, the majority of adult riders and pillions wore helmets (93.4% and 85.8%, respectively), however a substantial proportion (40%) did not fasten their helmet properly. Of children observed on motorcycles, only 30.5% wore helmets.This study shows low seat-belt and helmet wearing rates, despite enactment of legislation that requires all vehicle passengers to be restrained and for all motorcyclists to wear helmets. This was particularly evident for children (front and rear seating positions) and rear seat adult passengers. It is suggested there is a general lack of awareness of safety and the benefits of restraint/helmet use, and lack of adequate and appropriate enforcement. The implications of the findings are discussed in terms of promoting restraint/helmets use, enforcement of legislation and implementation of technologies to increase appropriate restraint/helmet use.  相似文献

The associations between celebrity, parental attachment, and adult adjustment were examined among 74 famous, former young performers in television and film. As adults, former young performers whose parents served as their professional managers viewed their mothers as less caring and more overcontrolling than did performers whose parents were not their managers. Other factors affecting the quality of the parent-child relationship included dissatisfaction with money management, poor peer support, the perception that involvement in acting was determined by others, and the specific nature of professional experience. Together, these variables accounted for 59% of the variance in perceived caring and 40% of the variance in perceived autonomy support. The relation could not be attributed to a generalized response bias, as attachment was unrelated to degree of positive thinking. A Celebrity times Parental Attachment interaction indicated that the quality of the parent-child relationship moderated the effects of celebrity on adult adjustment: Among participants with good parental attachment, there was no relation between professional experience and adjustment; however, among participants with poor attachment, this relation was strong. Possible implications for parenting child actors and analogous populations of talented children in high-stress arenas are discussed.  相似文献

ABSTRACT In this article we studied relations between self-rated emotional experience and the five-factor model of personality. Replicating previous findings we found that two dominant dimensions of emotional experience, Negative Affect and Positive Affect (that accounted for three to five times more total variance among Estonian emotion-related terms than any other factors) are selectively related to Neuroticism and Extraversion. Data supported the hierarchical taxonomy scheme proposed by Watson and Clark (1992) in which two broad higher order affective states were each composed of several correlated but still clearly distinguishable moods with their specific content. The content of specific emotions mapped systematically onto measures of personality: Affect scales explained 40% to 50% of the total variance of Neuroticism, Extraversion, and Conscientiousness, approximately 20% of the total variance of Agreeableness, and only 13% of Openness to Experience. Besides the replication of the hierarchical bipartite structure of emotion terms itself in a non-Indo-European language, our data demonstrated that the general pattern of associations between affect and personality domains is also generalizable across languages and cultures.  相似文献

This study investigates the long-term effects of parental divorce on adolescent psychological adjustment and well-being, and to what extent the effects are accounted for by parental psychological distress. Data were collected among 8,984 Norwegian adolescents (13-19 years) and their parents. Outcome variables were symptoms of anxiety and depression, subjective well-being, and three areas of school problems. Parental divorce was found to be associated with both higher mean levels and larger variances in adolescent problems. Divorce and parental distress contributed independently to adolescent distress, supporting the notion of "double exposure" effects. The prevalence of adolescents with substantial distress symptoms was 14% among those with non-distressed non-divorced parents and 30% among those with divorced and distressed parents. In general effects remained when controlling for demographic factors. Long-term effects of divorce on symptoms of anxiety and depression were stronger among girls than among boys.  相似文献

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) is a 478-item test that represents a substantial revision of the original form of the MMPI. This investigation sought to identify the item-level factor structure of the MMPI-A and also examined the scale-level factor structure of the 69 scales and subscales of this instrument. The study utilized the 1,620 normal adolescents (805 boys and 815 girls) of the normative sample for the MMPI-A. These adolescents ranged in age from 14 to 18 inclusive, with a mean age of 15.54 for boys and 15.60 for girls. A principal factor analysis of item-level responses resulted in extraction of 14 factors that were subjected to promax (oblique) rotation procedures. These 14 factors incorporated 81% of the total MMPI-A item pool and accounted for 44% of the total item-level response variance. For the scale-level analysis, 8 factors were selected for extraction and submitted to promax rotation procedures. These eight factors accounted for a total of 93.5% of the total variance in MMPI-A scale and subscale raw scores, Item-level results were discussed in terms of areas of congruence and dissimilarities from previously reported MMPI factor analyses in adolescent and adult samples, and scale-level factor results were presented in terms of clinical implications for the interpretation of MMPI-A scales and subscales.  相似文献

In a study of relationships between locus of control and perceived parental acceptance-rejection as they vary by age, 271 boys and girls from 9 through 11 years of age were administered the Nowicki-Strickland Locus of Control Scale, short form, and the Parental Acceptance-Rejection Questionnaire. A multiple regression/correlation analysis revealed that internality increased significantly with children's age and with children's perceptions of increased parental acceptance. Moreover, age and parenting jointly accounted for 22% of the variance in children's locus of control scores.  相似文献

This study examined the extent to which individual differences in alcohol and marijuana use among 167 Black university students could be accounted for by degree of ethnic identity. After controlling for year in school, sex, and friends' substance use, higher levels of ethnic identity indeed were found to be significantly related to lower beer/hard liquor use, wine use, and marijuana use, accounting for approximately 31%, 6%, and 4% of the variance, respectively. For marijuana use, however, friends' substance use accounted for more of the variance (13%) than did ethnic identity (4%).  相似文献
