Missing data techniques for structural equation modeling 总被引:2,自引:0,他引:2
Allison PD 《Journal of abnormal psychology》2003,112(4):545-557
As with other statistical methods, missing data often create major problems for the estimation of structural equation models (SEMs). Conventional methods such as listwise or pairwise deletion generally do a poor job of using all the available information. However, structural equation modelers are fortunate that many programs for estimating SEMs now have maximum likelihood methods for handling missing data in an optimal fashion. In addition to maximum likelihood, this article also discusses multiple imputation. This method has statistical properties that are almost as good as those for maximum likelihood and can be applied to a much wider array of models and estimation methods. 相似文献

This study examined the psychometric properties of the parent version of the Spence Children's Anxiety Scale (SCAS-P); 484 parents of anxiety disordered children and 261 parents in a normal control group participated in the study. Results of confirmatory factor analysis provided support for six intercorrelated factors, that corresponded with the child self-report as well as with the classification of anxiety disorders by DSM-IV (namely separation anxiety, generalized anxiety, social phobia, panic/agoraphobia, obsessive-compulsive disorder, and fear of physical injuries). A post-hoc model in which generalized anxiety functioned as the higher order factor for the other five factors described the data equally well. The reliability of the subscales was satisfactory to excellent. Evidence was found for both convergent and divergent validity: the measure correlated well with the parent report for internalizing symptoms, and lower with externalizing symptoms. Parent-child agreement ranged from 0.41 to 0.66 in the anxiety-disordered group, and from 0.23 to 0.60 in the control group. The measure differentiated significantly between anxiety-disordered children versus controls, and also between the different anxiety disorders except GAD. The SCAS-P is recommended as a screening instrument for normal children and as a diagnostic instrument in clinical settings. 相似文献

For certain crimes there is a tendency in the United States to blame individuals for their victimization. Previous work has shown that affective states can impact blame attribution. Drawing upon this work, the purpose of the current pre-registered research was to examine the relation between affective disgust and victim blame attribution. In Study 1, as participants’ (N = 203) level of implicit disgust associations with gay men increased, their tendency to blame a gay male homicide victim also increased, whereas their agreement that the homicide qualified as a hate crime decreased. In Study 2, disgust was experimentally induced by exposing participants (N = 431) to disgusting (e.g., vomit, insects) or neutral images (e.g., mug, stapler). Inducing disgust increased victim blame and decreased perceptions that the homicide constituted a hate crime. However, exploratory mediation analyses in both studies showed that the impact of disgust on hate crime applications is best explained as an indirect effect of victim blame. Taken together, these findings suggest that both individual differences in implicit gay-disgust and situational feelings of disgust may underlie people’s perceptions of how blameworthy a victim is for the crime committed against them. 相似文献

Stress- and trauma-related disorders, including posttraumatic stress disorder (PTSD), are characterized by an increased sensitivity to threat cues. Given that threat detection is a critical function of olfaction and that combat trauma is commonly associated with burning odors, we sought a better understanding of general olfactory function as well as response to specific trauma-related (i.e. burning) odors in combat-related PTSD. Trauma-exposed combat Veterans with (n = 22) and without (n = 25) PTSD were assessed for general and specific odor sensitivities using a variety of tools. Both groups had similar general odor detection thresholds. However, the combat Veterans with PTSD, compared to combat Veterans with comparable trauma exposure but without PTSD, had increased ratings of odor intensity, negative valence, and odor-triggered PTSD symptoms, along with a blunted heart rate in response to burning rubber odor. These findings are discussed within the context of healthy versus pathological changes in olfactory processing that occur over time after psychological trauma. 相似文献

The majority of intimate partner violence (IPV) research explores partner violence without considering the influence of contextual and psychosocial factors, such as trait aggression, psychopathology, gender, and provocation. Disparities in the general aggression literature further underscore the need to develop a better understanding of contextual and psychosocial factors. The present study sampled 720 (male = 365, female = 355) college students who completed measures of IPV perpetration and victimization, trait aggression, and psychopathology. Participants then completed a learning task, during which half were randomly selected to be provoked. The interactive effects of condition, gender, and perpetrator status on mood and aggressive responding were explored. Results indicated that perpetrators of both genders had similar emotional responses to provocation, but behavioral responses to provocation varied. Results were discussed in terms of their implication for future research and batterer intervention. 相似文献

A between-subjects experiment examined selective exposure to films in an imagined self-control scenario, and if exposure would be systematically related to perceptions of the film content as challenging, enjoyable, and a should versus a want choice. Across 3 measures of selective exposure—using open-ended choice, closed-ended choice, and prospective ratings—participants in the depletion condition were less likely to select films that were cognitively challenging, affectively challenging, or a should choice. In contrast to nondepleted participants, depleted participants were more likely to select films they expected being fun, suspenseful, and less appreciated. These results provide support for the proposition that users’ momentary self-control capacity and their perception of challenge provided by content predict media choice. 相似文献

In the past decade, cognitive biases and physiological arousal have each been proposed as mechanisms through which paediatric anxiety develops and is maintained over time. Preliminary studies have found associations between anxious interpretations of ambiguity, physiological arousal, and avoidance, supporting theories that link cognition, psychophysiology, and behaviour. However, little is known about the relationship between youths’ resolutions of ambiguity and physiological arousal during acute stress. Such information may have important clinical implications for use of verbal self-regulation strategies and cognitive restructuring during treatments for paediatric anxiety. In this brief report, we present findings suggesting that anxious, but not typically developing, youth select avoidant goals via non-threatening resolution of ambiguity during a stressor, and that this resolution of ambiguity is accompanied by physiological reactivity (heart rate, heart rate variability, and respiratory sinus arrhythmia). We propose future empirical research on the interplay between interpretation bias, psychophysiology, and child anxiety, as well as clinical implications. 相似文献

There is convincing evidence of the transmission of anxiety and depression from parents to children; however, mechanisms by which this vulnerability is passed on are unclear. Cognitive models and a small body of cross-sectional research suggest that parental attention biases (ABs) may be one mechanism involved in transmission. Longitudinal associations of maternal and offspring ABs with offspring symptoms have been scarcely studied. Forty-three mothers–child dyads were included. All children (7–12 years old) were diagnosis-free while 24 mothers had a lifetime emotional disorder (anxiety or depression) (high risk, HR) and 19 mothers had no psychiatric diagnoses (low risk, LR). This study examined cross-sectional and longitudinal associations of maternal and child AB and child anxiety symptomology at initial and 12-month assessments. ABs were assessed using a visual-probe task with emotional faces. There was a significant cross-sectional but not longitudinal association of increased child anxiety symptoms with increased maternal threat AB for HR but not LR dyads. At the cross-sectional level, increases in HR but not LR offspring anxiety symptomology were associated with maternal threat AB. Larger longitudinal studies are required that examine the interplay between parent–child variables and include multiple time-points of assessment and measures of AB. 相似文献

Attention-deficit hyperactivity disorder (ADHD) persists into adulthood in over 50% of cases, although its associated symptom profiles, comorbid problems, and neuropsychological deficits change substantially across development. Sluggish cognitive tempo (SCT) symptoms may contribute to associations between ADHD and comorbid problems and may partially explain the substantial heterogeneity observed in its correlates. 349 adults aged 18–38 years (M = 23.2, SD = 4.5, 54.7% male, 61.03% with ADHD) completed a multi-informant diagnostic procedure and a comprehensive neuropsychological battery. Adults with ADHD (n = 213) were retained for analyses. Latent class analyses (LCA) revealed three profiles of SCT symptoms among those with ADHD, which we classified as minimal, moderate, or severe SCT. Multiple analysis of covariance (MANCOVA) revealed significant differences among these profiles, which remained when controlling for persistence of ADHD symptoms and sex. In general, adults with ADHD combined with SCT symptoms (moderate and severe) had significantly more symptoms of anxiety, depression, and persistent inattention, and had more severe professional and relational impairment compared to ADHD adults without SCT. Compared to those with moderate or minimal SCT symptoms, the severe SCT group had the most symptoms of depression and internalizing disorders, and the most impairment in the domain of daily responsibility. No significant differences based on externalizing symptoms emerged when controlling for sex and persistence of inattention symptoms, suggesting the moderate and severe SCT groups do not simply reflect more symptoms. Moreover, follow-up mediation analyses revealed that SCT might at least partially explain the heterogeneity in ADHD. Findings have implications for refinement of etiological conceptualization, assessment methods, and intervention strategies. 相似文献
