Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to investigate the factor structure of coping in mothers with high levels of life stress. In Study 1, EFA of the Coping Orientation to Problems Experienced (C. S. Carver, M. F. Scheier, & J. K. Weintraub, 1989) in a sample of mothers of full-term or very low birth weight 2-year-old children yielded 7 reliable coping factors. Each factor accounted for significant variance in at least 1 of 6 outcomes measuring maternal-child well-being. In Study 2, CFA was used to cross-validate the EFA model on the basis of the responses of mothers of 2-year-old children with prenatal polysubstance exposure. CFA results revealed a moderately good fit, confirming the factor structure in a 2nd, independent sample of mothers with high levels of life stress. 相似文献

224 suicides from the Golden Gate Bridge in 1999-2009 were younger than other suicides handled by the Marin County Coroner but did not differ by sex or race. Those witnessed did not differ from those not witnessed. Compared to suicides from the bridge in the 1970s, recent suicides were older, more often male, and more often nonwhite. 相似文献

Merenda (1987) presented an interesting view of the prevalence of Galen's (cited in Kant, 1978) four temperaments in modern psychological theories of personality and of the different ways in which psychological theorists have attempted to account for Galen's four types. However, Merenda drew a parallel between Galen's four types and modern four-factor theories of personality. This is an error, as I explain herein. 相似文献

The U.S. Army developed the Global Assessment Tool (GAT) to monitor psychosocial fitness and well-being among soldiers and provide a means to objectively gauge the success of newly implemented resilience training programs. Despite its widespread use (taken over 5.2 million times) and stated utility for program evaluation, there is relatively little published evidence regarding the GAT’s reliability and validity. We used exploratory structural equation modeling (ESEM) with 4 random samples of soldiers (n = 10,000 each) to examine the factorial validity and reliability of the GAT. An 11-factor solution (Self-Management, Positive Affect, Meaning, Work Engagement, Organizational Trust, Loneliness, Negative Cognitions, Hostility, Negative Emotions, Depressive Symptoms, and Emotion-Focused Coping), with 4 additional factors assessing character strengths (Intellect, Warmth, Civic Strengths, and Temperance), fit well and replicated in a second random sample. A higher order, 2-factor model using composites scores and positing positive and negative psychosocial competencies also fit well. Tests of measurement invariance using a third random sample reinforced consistent measurement properties across gender, age, and rank, with the exception of character strengths, which produced different factor structures for males and females. Further validity tests using a fourth random sample underscored a modicum of divergence among the resilience factors and convergence among the character strengths factors. We conclude with recommendations for enhancing and refining the GAT and discuss the GAT’s utility as a reliable, multidimensional psychosocial assessment that can be used to evaluate the efficacy of military resilience training programs. 相似文献

To explore the associations between religiosity, health, and psychopathology, samples of 460 Kuwaiti and 274 American college students were recruited. Religiosity, pessimism, anxiety, obsession-compulsion, death obsession, and ego-grasping were significantly higher among the Kuwaitis than among their American counterparts. On the other hand, self-ratings of mental health and optimism were significantly higher among the Americans than their Kuwaiti counterparts. Religiosity was significantly and positively associated with ratings of physical health, mental health, and optimism (both countries), and negatively with pessimism, anxiety, suicidal ideation, and ego-grasping (Kuwaitis), and pessimism and suicidal ideation (Americans). A factor analysis of the correlational matrix yielded in both countries two independent factors labeled “Normality vs. psychopathology”, and “Religiosity, health, and optimism”. Backward multiple regressions revealed that the main predictors of religiosity were mental health, optimism and physical health positively, and obsession-compulsion and ego-grasping negatively in Kuwaitis; and optimism positively and anxiety, and suicidal ideation negatively in Americans. By and large, those who consider themselves as religious were more healthy and optimistic, and obtained lower scores on psychopathology in both countries. 相似文献

In this study, we investigated when visual perception begins in fixations. During picture viewing, the picture was degraded at the beginning of selected saccades and changed back to the original after varying intervals. Participants manually responded whenever they detected changes. The change-backs were undetected when they occurred <6 msec after the end of the saccade, marked by the peak of the overshoot in dual Purkinje image eyetracker data, and detection reached asymptote 32 msec after that marker. Eye velocity at the change-backtime also affected detection likelihood. Apparently, perception begins around the time at which the eyes stop rotating at the end of a saccade, giving a psychological justification for measuring fixation durations from then. This also specifies the deadline for gaze-contingent display changes to occur without detectable image motion. Investigators using the dual PurMnje image eyetracker should consider the peak of the overshoot as the fixation onset time and measure intrafixational presentation times from then. 相似文献
