Intolerance of uncertainty moderates the relations among religiosity and motives for religion, depression, and social evaluation fears.

OBJECTIVES: Intolerance of uncertainty (IU) underlies several psychological disorders, and religion may help some individuals cope with IU and/or protect against psychological symptoms. It was hypothesized that IU would moderate the relations between coping motives for being religious, as well as religiosity, and common psychological disorder symptoms: Depression and social evaluation fears. METHODS: Study 1 included 473 self-reporting community members (M age = 48, 48% female, 80% Protestant/Catholic). Study 2 included 412 self-reporting undergraduates ( M age = 19, 71% female, 76% Protestant/Catholic). RESULTS: For Study 1, coping-based motives related to greater depression for young adults with above-average IU and to lower depression for young adults with below-average IU. For Study 2, religiosity related to lower depression and fear of negative evaluation for individuals with above-average IU and to greater fear of positive evaluation for individuals with below-average IU. CONCLUSION: IU may be an important mechanism between aspects of religion and psychological disorder symptoms.

A psychometric evaluation of hierarchical and oblique versions of five variants of the Posttraumatic Growth Inventory.

The Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996) is the most commonly used measure of posttraumatic growth. Although the original five factor structure has extensive psychometric support, evidence exists for alternate PTGI models. The current study assessed the validity of oblique and hierarchical factor structures of five PTGI models. Confirmatory factor analyses were performed among a heterogeneous community sample with a diverse trauma history. The oblique models provided a better fit to the data compared with their respective hierarchical models. Three oblique variants provided good fit to the data on two fit indices and all five oblique variants met the recommended criteria for at least one fit index. The 10-item model demonstrated the lowest Expected Cross-Validation Index (ECVI) values and is a brief and useful measure when examining PTGI total scores; however, current results suggest that consideration of the specific subscales may be more meaningful than total scores. Researchers and clinicians interested in subscale scores should consider using the 18- or 21-item variants due to a higher number of items per factor and, therefore, greater factor stability. Future directions in refining and measuring posttraumatic growth are discussed.

Trauma-Exposed Community-Dwelling Women and Men Respond Similarly to the DAR-5 Anger Scale: Factor Structure Invariance and Differential Item Functioning.

Anger is associated with the development of posttraumatic stress disorder (PTSD) and with poor treatment outcomes. The Dimensions of Anger Reactions Scale-5 (DAR-5) has demonstrated preliminary evidence of unitary factor structure and sound psychometric properties. Gender-based differences in psychometric properties have not been explored. The current study examined gender-based factor structure invariance and differential item functioning of the DAR-5 and gender differences in PTSD symptoms as a function of anger severity using a community sample of adults who had been exposed to trauma. Data were collected from 512 trauma-exposed community-dwelling adults (47.9% women). Confirmatory factor analyses, Mantel-Haenszel χ(2) tests and a comparison of characteristic curves, and 2-way analyses of variance, respectively, were used to assess gender-based factor structure invariance, gender-based response patterns to DAR-5 items, and gender differences in PTSD symptoms as a function of anger. The unitary DAR-5 factor structure did not differ between men and women. Significant gender differences in the response pattern to the DAR-5 items were not present. Trauma-exposed individuals with high anger reported greater overall PTSD symptoms (p < .001), regardless of gender. The DAR-5 can be used to assess anger in trauma-exposed individuals without concern of gender biases influencing factor structure or item functioning. Findings further suggested that the established relationship between anger and PTSD severity did not differ by gender.

A randomized controlled trial of attention modification for social anxiety disorder.

Social Anxiety Disorder (SAD) models implicate social threat cue vigilance (i.e., attentional biases) in symptom development and maintenance. A modified dot-probe protocol has been shown to reduce SAD symptoms, in some but not all studies, presumably by modifying an attentional bias. The current randomized controlled trial was designed to replicate and extend such research. Participants included treatment-seeking adults (n = 108; 58% women) who met diagnostic criteria for SAD. Participants were randomly assigned to a standard (i.e., control) or modified (i.e., active) dot-probe protocol condition and to participate in-lab or at home. The protocol involved twice-weekly 15-min sessions, for 4 weeks, with questionnaires completed at baseline, post-treatment, 4-month follow-up, and 8-month follow-up. Symptom reports were assessed with repeated measures mixed hierarchical modeling. There was a main effect of time from baseline to post-treatment wherein social anxiety symptoms declined significantly (p < .05) but depression and trait anxiety did not (p > .05). There were no significant interactions based on condition or participation location (ps > .05). Reductions were maintained at 8-month follow-up. Symptom reductions were not correlated with threat biases as indexed by the dot-probe task. The modified and standard protocol both produced significant sustained symptom reductions, whether administered in-lab or at home. There were no robust differences based on protocol type. As such, the mechanisms for benefits associated with modified dot-probe protocols warrant additional research.

Comparing short forms of the Social Interaction Anxiety Scale and the Social Phobia Scale.

The Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS; Mattick & Clarke, 1998) are companion scales developed to measure anxiety in social interaction and performance situations, respectively. The measures have strong discriminant and convergent validity; however, their factor structures remain debated, and furthermore, the combined administration length (i.e., 39 items) can be prohibitive for some settings. There have been 4 attempts to assess the factor structures of the scales and reduce the item content: the 14-item Social Interaction Phobia Scale (SIPS; Carleton et al., 2009), the 12-item SIAS-6/SPS-6 (Peters, Sunderland, Andrews, Rapee, & Mattick, 2012), the 21-item abbreviated SIAS/SPS (ASIAS/ASPS; Kupper & Denollet, 2012), and the 12-item Readability SIAS and SPS (RSIAS/RSPS; Fergus, Valentiner, McGrath, Gier-Lonsway, & Kim, 2012). The current study compared the short forms on (a) factor structure, (b) ability to distinguish between clinical and non-clinical populations, (c) sensitivity to change following therapy, and (d) convergent validity with related measures. Participants included 3,607 undergraduate students (55% women) and 283 patients with social anxiety disorder (43% women). Results of confirmatory factor analyses, sensitivity analyses, and correlation analyses support the robust utility of items in the SIPS and the SPS-6 and SIAS-6 relative to the other short forms; furthermore, the SIPS and the SPS-6 and SIAS-6 were also supported by convergent validity analyses within the undergraduate sample. The RSIAS/RSPS and the ASIAS/ASPS were least supported, based on the current results and the principle of parsimony. Accordingly, researchers and clinicians should consider carefully which of the short forms will best suit their needs.
