ABSTRACT: Data from 17 adolescents who attempted suicide and came to the attention of the Payne Whitney Suicide Prevention Clinic during the years 1968–70 were analyzed for information regarding sex, birth order, sex of siblings, and family constellation. The results indicated that there was a significant trend for firstborn females to be overrepresented among adolescent suicide attempters. In addition, father loss was frequently noted in their histories. A theoretical rationale for the investigation is presented with the results of the study.  相似文献

Validation of psychosocial measures for use in mammography screening research has been given inadequate attention in the literature. The authors report on the validation of 5 measures examining 4 attitudinal constructs (i.e., pros, cons, outcome expectations, and cancer worries) and 1 social influence construct (i.e., subjective norms) in a 22-item inventory. The study participants consisted of a national, randomly sampled population of women veterans (n = 2,910). After minor revision of scales, the authors found independent measures for 4 constructs: pros, cons, cancer worries, and subjective norms. The authors concluded that these scales have acceptable psychometric properties; support construct validity; and provide brief, reliable, and valid measures of attitudes toward and norms regarding mammography screening. These scales may be useful for intervention research.  相似文献

Different theoretical contentions on gender differences in loneliness exist, often including the emergence of gender differences in particular developmental periods. To explain those ideas, the current meta‐analysis synthesizes the available evidence on gender differences in loneliness across the lifespan. Three‐level meta‐analyses were conducted with 751 effect sizes, covering 399,798 individuals (45.56% males). Results showed a close‐to‐zero overall effect (g = 0.07). Most examined moderators were non‐significant, except for age, the scope of the sampling area, and year of publication. Most importantly, all effects were small, suggesting that across the lifespan mean levels of loneliness are similar for males and females.  相似文献

The authors tested associations between glycated hemoglobin (HbA1c; an index of glucose homeostasis and an indicator of cardiovascular disease risk in nondiabetic populations) and socioeconomic status (defined by grade of employment) and psychosocial factors in 234 British civil servants. HbA1c concentration was inversely related to grade of employment. Higher HbA1c was associated with greater waist-hip ratio, lower control at work, lower internal locus of control, lower active coping, and lower social support. Control at work, internal and chance locus of control, and active coping were also related to socioeconomic status. The association of social support but not other psychosocial factors with HbA1c was independent of socioeconomic status. HbA1c may complement measures of the metabolic syndrome and insulin resistance in studies of psychosocial factors in cardiovascular disease risk.  相似文献

For youth raised in the Digital Age, online risks such as cyberbullying and sexting have become increasingly problematic. Since digital media is primarily consumed at home, parents play an important role in mitigating these risks; parents can teach children about online dangers, regulate the amount of time spent online, and, to some extent, curate the online content children see. The present study evaluated the psychometric properties of a four-factor media parenting measurement model introduced by Livingstone et al. (2011) across self-reports of a U.S. sample of parents (Mage?=?38.5) and children (ages 10–14; Mage?=?11.8). To identify meaningful group differences, latent mean comparisons were evaluated across youth age and gender. Confirmatory Factor Analysis results provided good fit to the data for the four-factor media parenting model based on both parent [χ2(201, n?=?306)?=?384.407; RMSEA(.046—.063)?=?.055; CFI?=?.958; TLI/NNFI?=?.951; SRMR?=?.050] and child report [χ2(203, n?=?306)?=?378.033; RMSEA(.045-.061)?=?.053; CFI?=?.942; TLI/NNFI?=?.934; SRMR?=?.060]. The final latent parenting factors included: Active Mediation, Monitoring, Technology Control, and Restrictive Mediation. Latent mean comparisons revealed that parents of girls reported higher levels of Monitoring than parents of boys, whereas girls reported higher levels of parental Restriction than boys. Similarly, older children and their parents reported lower Restriction than younger children and their parents. Overall, latent mean differences identified between media parenting domains may be important for youth outcomes and provide support for their inclusion as distinct factors in predictive models.
