Model comparison of nonlinear structural equation models with fixed covariates

Recently, it has been recognized that the commonly used linear structural equation model is inadequate to deal with some complicated substantive theory. A new nonlinear structural equation model with fixed covariates is proposed in this article. A procedure, which utilizes the powerful path sampling for computing the Bayes factor, is developed for model comparison. In the implementation, the required random observations are simulated via a hybrid algorithm that combines the Gibbs sampler and the Metropolis-Hastings algorithm. It is shown that the proposed procedure is efficient and flexible; and it produces Bayesian estimates of the parameters, latent variables, and their highest posterior density intervals as by-products. Empirical performances of the proposed procedure such as sensitivity to prior inputs are illustrated by a simulation study and a real example.This research is fully supported by a grant from the Research Grant Council of the Hong Kong Special Administrative Region, China (Project No. CUHK 4346/01H).

The Relation Between Coordinated Interpersonal Timing and Maternal Sensitivity in Four-Month-Old Infants

The relation between mother–infant coordinated interpersonal timing, an automated microanalytic measure of dyadic vocal coordination, and maternal sensitivity was explored. Thirty-five mothers and their developmentally normal 4-month-old infants were audio-recorded during a 20-min laboratory vocal interaction session, that was later analyzed for degree of vocal coordination. Maternal Sensitivity ratings (Ainsworth & Bell, 1969) were based on a video-taped 45-min unstructured laboratory interaction period. A significant curvilinear relation between the degree to which mother coordinated her noninterruptive co-occurring speech to that of her infant was found and revealed that mothers highest in sensitivity were characterized by moderate levels of coordination. Examining mother-infant interaction at the specific behavioral level, while incorporating tests of nonlinear trends, may provide important information about the nature of sensitive parenting.     

Predictors of Self-Reported Anxiety and Panic Symptoms: An Evaluation of Anxiety Sensitivity, Suffocation Fear, Heart-Focused Anxiety, and Breath-Holding Duration

The purpose of this study was to examine the extent to which anxiety-related individual difference variables predict anxious responding when individuals experience aversive bodily sensations. Thus, we explore several psychological and behavioral predictors of response to a single 25-sec inhalation of 20% carbon dioxide-enriched air in 70 nonclinical participants. Predictor variables included anxiety sensitivity, suffocation fear, heart-focused anxiety, and breath-holding duration. Multiple regression analyses indicated that only anxiety sensitivity significantly predicted postchallenge panic symptoms, whereas both anxiety sensitivity and suffocation fear predicted postchallenge anxiety. These data are in accord with current models of panic disorder that emphasize the role of fear of fear in producing heightened anxiety and panic symptoms and help clarify specific predictors of anxiety-related responding to biological challenge.     

Assessment of Disgust Sensitivity in Children With an Age-Downward Version of the Disgust Emotion Scale

The present study examined the psychometric properties of the Disgust Emotion Scale for Children (DES-C). Principal components analysis of the DES-C data revealed five factors reflecting disgust toward (a) rotting foods, (b) injection and blood, (c) odors, (d) mutilation and death, and (e) animals, which were largely in keeping with the intended subscales. The DES-C showed good reliability, excellent convergent validity (as established by correlations with an alternative self-report index of disgust), fairly good predictive validity (as assessed by correlations with measures of fear/anxiety and a behavioral index of disgust), and acceptable parent–child agreement (in particular with the mothers). Importantly, the DES-C proved to perform better on some psychometric indicators than an age-downward version of the Disgust Scale. These findings indicate that the DES-C should be regarded as the preferred scale for measuring disgust sensitivity and its role in the etiology and maintenance of anxiety problems in children.     

Maternal sensitivity during distressing tasks: a unique predictor of attachment security

The extent to which maternal sensitivity during a non-arousing free play task and during distressing tasks at 6 months predicted infant-mother attachment security was examined. When considered simultaneously, only maternal sensitivity during distressing tasks predicted subsequent attachment security. Infant temperament was unrelated to attachment security.     

Specific and differential prediction of health anxiety by disgust sensitivity and propensity

Current models of health anxiety suggest that fear resulting from false alarms to perceived threats to one's health results in the development of hypochondriasis and related disorders. Disgust has been proposed as an affective response that may function as an etiological and maintenance mechanism in health anxiety. Moreover, the way in which an individual perceives the disgust response (disgust sensitivity) may affect health anxiety, separately from their likelihood of experiencing disgust (disgust propensity). The present study utilized multiple hierarchical regression analysis to investigate the degree to which self-reported disgust sensitivity and disgust propensity differentially predict elevated health anxiety in a sample of 620 non-treatment-seeking undergraduates. Further, this effect is tested in comparison to that of anxiety sensitivity, a construct demonstrated to be strongly related to health anxiety. Analyses indicate that disgust sensitivity, rather than disgust propensity, is primarily responsible for this relation. An additional analysis tested the specificity of disgust sensitivity relative to anxiety sensitivity. Disgust sensitivity was no longer significant after including anxiety sensitivity in the model. Suggestions for further evaluation of this relation are provided. These results suggest that although disgust sensitivity may appear related to health anxiety, this relation may be confounded by anxiety sensitivity.     

Gender variance in interreligious sensitivity among Finnish pupils

This paper examines gender variance in the interreligious sensitivity among Finnish children and youth using a non-probability sample of 1000 Finnish lower secondary school pupils representing the age group 12–16. The data were gathered in three geographical locations: the capital city of Helsinki area, and two smaller municipalities in other parts of the country. The pupils’ self-reported attitudes towards interreligious sensitivity were measured using the Interreligious Sensitivity Scale. The results showed significant variation between the genders in the pupils’ interreligious sensitivity. Also geographical variance (city of residence) and pupils’ religious affiliation influenced their interreligious sensitivity.     

The mediating role of disgust sensitivity and thought‐action fusion between religiosity and obsessive compulsive symptoms

Psychological theories of obsessions and compulsions have long recognised that strict religious codes and moral standards might promote thought‐action fusion (TAF) appraisals. These appraisals have been implicated in the transformation of normally occurring intrusions into clinically distressing obsessions. Furthermore, increased disgust sensitivity has also been reported to be associated with obsessive compulsive (OC) symptoms. No research, however, has investigated the mediating roles of TAF and disgust sensitivity between religiosity and OC symptoms. This study was composed of 244 undergraduate students who completed measures of OC symptoms, TAF, disgust sensitivity, religiosity and negative effect. Analyses revealed that the relationship between religiosity and OC symptoms was mediated by TAF and disgust sensitivity. More importantly, the mediating role of TAF was not different across OC symptom subtypes, whereas the mediating role of disgust sensitivity showed different patterns across OC symptom subtypes. These findings indicate that the tendency for highly religious Muslims to experience greater OC symptoms is related to their heightened beliefs about disgust sensitivity and the importance of thoughts.     

My mother is sensitive,but I am too tired to know: Infant sleep as a moderator of prospective relations between maternal sensitivity and infant outcomes

This study investigated the moderating role of infant sleep in the connections between maternal sensitivity and three indicators of infant functioning: attachment security, theory of mind, and executive functioning (EF). Maternal sensitivity was assessed when infants (27 girls and 36 boys) were 1 year of age. Infant sleep was assessed with actigraphy at age 2; attachment security, theory of mind, and EF were also assessed at age 2. Results indicated that maternal sensitivity was positively related to attachment security only among infants who got more sleep at night, and to conflict-EF and theory of mind only for infants who got greater proportions of their sleep during the night. These results suggest that sleep may enhance the benefits of maternal sensitivity for some aspects of infants’ functioning, providing further support for the importance of sleep maturation as a salient developmental task of infancy.
