Worry has been described as a core feature of several disorders, particularly generalized anxiety disorder (GAD). The present study examined the latent structure of worry by applying 3 taxometric procedures (MAXEIG, MAMBAC, and L-Mode) to data collected from 2 large samples. Worry in the first sample (Study 1) of community participants (n = 1,355)…

This study compared low-income Mexican American parents of young children referred for behavior problems to their nonreferred counterparts on an observational measure of parent-child interactions. Referred Mexican American parents demonstrated more negative behaviors than their nonreferred counterparts in both nondirective and highly directive…

Selective mutism is a severe childhood disorder involving failure to speak in public situations in which speaking is expected. The present study examined 9 youths with selective mutism treated with child-focused, exposure-based practices and parent-focused contingency management via an alternating treatments design. Broadband measures of…

Alcohol expectancies have been associated with drinking behaviors among college students. Few studies, however, have focused on researcher-labeled ''positive'' and ''negative'' expectancies as well as the valuations (i.e., desirability) of these expectancies. Moreover, research on the correlates of heavy drinking among female college athletes…

Discomfort intolerance, defined as an individual difference in the capacity to tolerate unpleasant bodily sensations, is a construct recently posited as a risk factor for panic and anxiety psychopathology. The present report used a biological challenge procedure to evaluate whether discomfort intolerance predicts fearful responding beyond the…

We examined whether social anxiety resulted in different levels of perceived impairment in first- and second-generation students of Chinese heritage (ns=65 and 47) compared to their European-heritage counterparts (n=60). We also used a modified version of the Anxiety Disorders Interview Schedule (ADIS-IV) to determine whether the 3 groups…

The present study evaluated sex differences in observational fear conditioning using modeled ''mock'' panic attacks as an unconditioned stimulus (UCS). Fifty-nine carefully prescreened healthy undergraduate participants (30 women) underwent 3 consecutive differential conditioning phases: habituation, acquisition, and extinction. It was expected…

Over the past 3 decades we have witnessed an increase in the complexity of theoretical models that attempt to explain development in a number of behavioral domains. The conceptual movement to examine behavior from both developmental and contextual perspectives parallels recent methodological advances in the analysis of change. These new analysis…

A latent variable modeling approach to reliability and measurement invariance evaluation for multiple-component measuring instruments is outlined. An initial discussion deals with the limitations of coefficient alpha, a frequently used index of composite reliability. A widely and readily applicable structural modeling framework is next described…
