Context-specificity of relapse: effects of therapist and environmental context on return of fear.

Context-specificity of fear extinction was tested among 65 participants who were fearful of spiders by manipulating the contexts used for exposure treatment and two-week follow-up assessment. Context was defined by both meaningful (presence of a particular therapist) and incidental (room location and furnishings) environmental cues. Distinct phobic stimuli were used to examine interactions of context with stimulus. Physiological, behavioral and verbal indices of fear were measured. Results provided modest support for context-specific return of fear. With one stimulus, participants assessed in a non-treatment context at follow-up exhibited greater returns in heart rate levels. In addition, three of four participants who could not touch the stimulus at follow-up had been tested in a non-treatment context. Future investigations may benefit from greater distinctions between contexts or manipulation of contextual features more directly relevant to fear. Finally, post hoc analyses identified high trait anxiety, slow treatment response, recovery of phobic cognitions and long duration/high intensity phobic encounters post-treatment as significant predictors of increased return of fear.     

Path analytic examination of a cognitive model of PTSD

Ehlers and Clark (2000) developed a cognitive model of posttraumatic stress disorder (PTSD) symptom maintenance which implicated the role of posttraumatic cognitions and aspects of the trauma memory in maintaining symptoms via an increased sense of current threat. The aim of the current study was to empirically test a variant of this model using path analysis. Participants in the current study were 514 undergraduates at a midwestern university who reported experiencing at least one traumatic event. Path analyses examined various models of the possible relationships between one’s posttraumatic cognitions and the centrality of the traumatic event to the sense of self (considered an aspect of memory integration) in predicting current level of PTSD symptoms. Results indicate that both event centrality and posttraumatic cognitions are unique and independent predictors of current symptom level. Overall, the results of this study support aspects of Ehlers and Clark’s cognitive model of PTSD; cognitive appraisals of the self and centrality of the event were highly related to levels of distress. However, the current study suggests that overly integrated trauma memories may lead to greater distress and not poorly integrated ones as suggested by Ehlers and Clark.     

Psychometric properties of the mobility inventory for agoraphobia: convergent, discriminant, and criterion-related validity

Aims of this study were (a) to summarize the psychometric literature on the Mobility Inventory for Agoraphobia (MIA), (b) to examine the convergent and discriminant validity of the MIA's Avoidance Alone and Avoidance Accompanied rating scales relative to clinical severity ratings of anxiety disorders from the Anxiety Disorders Interview Schedule (ADIS), and (c) to establish a cutoff score indicative of interviewers’ diagnosis of agoraphobia for the Avoidance Alone scale. A meta-analytic synthesis of 10 published studies yielded positive evidence for internal consistency and convergent and discriminant validity of the scales. Participants in the present study were 129 people with a diagnosis of panic disorder. Internal consistency was excellent for this sample, α = .95 for AAC and .96 for AAL. When the MIA scales were correlated with interviewer ratings, evidence for convergent and discriminant validity for AAL was strong (convergent r with agoraphobia severity ratings = .63 vs. discriminant rs of .10–.29 for other anxiety disorders) and more modest but still positive for AAC (.54 vs. .01–.37). Receiver operating curve analysis indicated that the optimal operating point for AAL as an indicator of ADIS agoraphobia diagnosis was 1.61, which yielded sensitivity of .87 and specificity of .73.     

An Exploratory and Confirmatory Factor Analysis of the Affective Control Scale in an Undergraduate Sample

A considerable amount of clinical research interest has recently developed regarding emotion dysregulation and psychopathology. Many have suggested that distinct affective management deficits may characterize anxiety and mood pathology. Despite increased research attention, efforts to validate and sufficiently investigate the psychometric properties of many self-report measures of affect regulation have been lacking. The current study examined the response behavior of 1566 undergraduate participants who completed the Affective Control Scale (ACS). The ACS assesses fear of intense emotion, and it is frequently used in empirical research. The present investigation examined the structural qualities of the measure using exploratory and confirmatory factor analytic techniques. Findings suggest the original four rationally-derived subscales do not adequately fit the observed response patterns. Rather, results indicated that a five-factor solution that included a subscale measuring emotion mismanagement better represented response behavior. Additional normative data and bivariate correlations with other measures of emotion regulation and affect are presented.     

Siblings of Military Servicemembers: A Qualitative Exploration of Individual and Family Systems Reactions

How does having a sibling in the military affect young adults? Despite increasing attention to the challenges faced by spouses and children of servicemembers, the siblings of servicemembers have been largely ignored. This qualitative investigation uses unstructured narratives to explore siblings' perceptions of changes in their lives and changes in the family of origin associated with having a family member enlist in the United States military. Thematic analyses revealed an acute period of conflict followed by reorganization, awareness of the parents' distress, changes in the emotional climate of the family, shifts in family roles, admiration for the military sibling, and increased meaning and purpose for the family following the servicemember's enlistment. Computer-assisted text analyses revealed both positive and negative emotional content associated with the siblings' military service. For professional psychologists who come into contact with siblings of servicemembers, it is important to recognize that military enlistment can have ripple effects and complicate other common individual and family stresses. More generally, it is important to provide siblings and the family of origin with information about what to expect during and after the servicemember's enlistment, especially since these families may lack support and contact from others going through similar transitions.     

Emotion Regulation in Relation to Emerging Adults’ Mental Health and Delinquency: A Multi-informant Approach

Relative to the merits of authoritative parenting, potential adverse outcomes are well documented for authoritarian and permissive parenting. However, conclusions are typically drawn from single informants. The ability of youths’ emotion regulation skills to mediate outcomes in emerging adults has also not been fully explored. This study investigated whether emotion regulation mediated parenting style history and potential outcomes of mental health and delinquency. Parenting style history and emerging adults’ emotion regulation ability were reported by 110 youth and their caregivers; youth reported on mental health functioning and delinquency. Emerging adults’ emotion regulation ability partially mediated the association between authoritative parenting history and mental health functioning and authoritative parenting history was indirectly related to delinquency through emotion regulation; however, based on all reporters, emotion regulation ability was not associated with authoritarian or permissive parenting style history. Results support that the merits of authoritative parenting may lie in fostering better emotion regulation skills.     

Sensitizing Potential Jurors to Variations in Eyewitness Evidence Quality Using Counterfactual Thinking

Jurors often have difficulty evaluating eyewitness testimony. Counterfactual thinking is a type of mental simulation that informs causal inference. Encouraging jurors to think counterfactually about eyewitness factors may sensitize them to these factors' causal influence on eyewitness identification and testimony accuracy, improving their overall judgments (such as verdicts). One hundred twenty‐one undergraduate participants were randomly assigned to read a scenario containing either high‐quality or low‐quality eyewitness evidence and to evaluate eyewitness factors adopting either their default or a counterfactual mindset via a question‐order manipulation. Logistic regressions and analyses of variance revealed that a counterfactual mindset lowered perceptions of eyewitness accuracy and guilty verdicts (compared with the default mindset) when the evidence was poor; a counterfactual mindset, however, did not increase perceptions of accuracy and guilty verdicts when evidence was strong. We discuss possible mechanisms underlying these effects and identify several potential avenues for future research.Copyright © 2016 John Wiley & Sons, Ltd.     

Applying Bifactor Statistical Indices in the Evaluation of Psychological Measures

The purpose of this study was to apply a set of rarely reported psychometric indices that, nevertheless, are important to consider when evaluating psychological measures. All can be derived from a standardized loading matrix in a confirmatory bifactor model: omega reliability coefficients, factor determinacy, construct replicability, explained common variance, and percentage of uncontaminated correlations. We calculated these indices and extended the findings of 50 recent bifactor model estimation studies published in psychopathology, personality, and assessment journals. These bifactor derived indices (most not presented in the articles) provided a clearer and more complete picture of the psychometric properties of the assessment instruments. We reached 2 firm conclusions. First, although all measures had been tagged “multidimensional,” unit-weighted total scores overwhelmingly reflected variance due to a single latent variable. Second, unit-weighted subscale scores often have ambiguous interpretations because their variance mostly reflects the general, not the specific, trait. Finally, we review the implications of our evaluations and consider the limits of inferences drawn from a bifactor modeling approach.
