Does the Cognitive Fusion Questionnaire Measure More than Frequency of Negative Thoughts?

Cognitive fusion is a psychopathological process that appears to be relevant to a wide range of disorders. This process is frequently measured with the Cognitive Fusion Questionnaire (CFQ). However, the construct validity of similar measures has been criticized for substantial overlap with distress. It is possible the CFQ may excessively measure the presence of unwanted thoughts, rather than fusion per se. Therefore, this study examined the discriminant validity of the CFQ relative to a measure of automatic negative thoughts (the Automatic Thoughts Questionnaire) in a college student sample (n = 389). While the two measures were highly correlated (ρ = .74), exploratory factor analysis demonstrated that they consistently loaded onto separate factors. The CFQ also demonstrated incremental validity in predicting distress and anxiety over four weeks when controlling for baseline automatic negative thoughts. Overall findings are consistent with the CFQ measuring its intended construct, rather than the mere presence of negative thoughts. Major limitations to generalizability include the use of a college student sample with minimal racial and ethnic diversity, and the lack of additional comparator measures

A Proposed Beam-Beam Test Facility COMBINE

The COmpact Machine for Beam-beam Interactions in Non-Equilibrium systems (COMBINE) is a proposed, dedicated, beam-beam test facility. The base design would make use of a pair of identical octagonal rings (2.5 meters per side) one rotated 180 degrees from the other, meeting at their common interaction point. These would be fed by an electron gun producing up to 125 keV electrons. The low energy will allow for beam-beam tune shifts commensurate with existing colliders, some linac-ring type systems, and will also allow for an exploration of the predicted effects of gear-changing, which would be performed using a variable pathlength scheme. The low energy, and small size will allow for cost effective research, simulation code benchmarking, as well as training opportunities for students

A scanning tunneling microscopy based potentiometry technique and its application to the local sensing of the spin Hall effect

A scanning tunneling microscopy based potentiometry technique for the measurements of the local surface electric potential is presented and illustrated by experiments performed on current-carrying thin tungsten films. The obtained results demonstrate a sub-millivolt resolution in the measured surface potential. The application of this potentiometry technique to the local sensing of the spin Hall effect is outlined and some experimental results are reported.Comment: 9 pages and 4 figure

The Interaction of Mindful Awareness and Acceptance in Couples Satisfaction

Past studies indicate that the awareness and acceptance facets of trait mindfulness both independently predict relationship satisfaction. However, this study hypothesized that the combination of awareness and acceptance might be a stronger contributor to relationship functioning than either in isolation. Regression analyses were used to test whether mindful awareness and acceptance interact in predicting couples satisfaction in a sample of dating or married college students (n = 138). Acceptance was positively associated with couples satisfaction, while awareness was unrelated. These two mindfulness facets interacted such that greater awareness was related to poorer satisfaction when acceptance was low, but was unrelated when acceptance was high. Conversely, greater acceptance was only related to greater satisfaction when awareness was moderate or high. These results suggest the combination of high awareness and low acceptance can be problematic for relationships, while at least moderate mindful awareness is needed for acceptance to be beneficial

Longitudinal phase space manipulation in energy recovering linac-driven free-electron lasers

Energy recovering an electron beam after it has participated in a free-electron laser (FEL) interaction can be quite challenging because of the substantial FEL-induced energy spread and the energy anti-damping that occurs during deceleration. In the Jefferson Lab infrared FEL driver-accelerator, such an energy recovery scheme was implemented by properly matching the longitudinal phase space throughout the recirculation transport by employing the so-called energy compression scheme. In the present paper,after presenting a single-particle dynamics approach of the method used to energy-recover the electron beam, we report on experimental validation of the method obtained by measurements of the so-called "compression efficiency" and "momentum compaction" lattice transfer maps at different locations in the recirculation transport line. We also compare these measurements with numerical tracking simulations.Comment: 31 pages, 13 figures, submitted to Phys. Rev. Special Topics A&

Comparing Cognitive Fusion and Cognitive Reappraisal as Predictors of College Student Mental Health

Transdiagnostic cognitive behavioral interventions target different cognitive processes to promote mental health, including cognitive fusion and cognitive reappraisal. Determining the relative impact of cognitive fusion and reappraisal on a range of student mental health concerns could help interventions target psychopathological cognitive processes more effectively. Therefore, this study examined the longitudinal impact of cognitive fusion and reappraisal on mental health and functioning outcomes. A series of hierarchical regression models tested the effects of cognitive fusion and reappraisal in a sample of college students (n = 339). When controlling for reappraisal and baseline symptoms, fusion predicted distress, depression, generalized anxiety, social anxiety, hostility, academic distress, and student role problems 1 month later. Reappraisal predicted only student role problems longitudinally when controlling for fusion. These results suggest that cognitive fusion is a stronger predictor than reappraisal for a range of student mental health concerns and may be a particularly important target for improving student mental health

Examining Processes of Change in an Online Acceptance and Commitment Therapy Dismantling Trial with Distressed College Students

This secondary analysis examined the processes of change from a randomized dismantling trial evaluating the Open (i.e., cognitive defusion, acceptance) and Engaged (i.e., values, committed action) components of acceptance and commitment therapy (ACT). Analyses were conducted with 161 distressed college students randomly assigned to a full online ACT program (Full n=40), online ACT targeting the Open components (Open n=41) or targeting the Engaged components (Engaged n=39), or a waitlist condition (Waitlist n=41). The intervention occurred over six weeks followed by a post-treatment assessment with mental health symptoms as the primary outcome. Consistent with predictions, pre- to post-treatment improvements in global psychological inflexibility, cognitive fusion, acceptance, values, and committed action all predicted pre- to post-treatment improvements in mental health, with most processes continuing to independently predict improvements when included in a single model. The relations between changes in psychological flexibility and mental health were generally equivalent between conditions. Each psychological flexibility process separately mediated improvements in mental health for Engaged versus waitlist and Full versus waitlist conditions. However, global inflexibility, committed action, and values progress did not mediate effects for Open versus waitlist. Overall, results indicate a range of acceptance, defusion, values, and committed action processes are functionally relevant for outcomes with the Engaged components of ACT and Full ACT, but values, committed action, and global psychological inflexibility processes may be more weakly related to the effects of the Open components of ACT alone

A Randomized Trial of Acceptance and Commitment Therapy and Traditional Cognitive-Behavioral Therapy Self-Help Books for Social Anxiety

Background: Self-help resources such as books may help meet critical mental health needs in college students, but there is insufficient evidence on whether and how such books work. This randomized trial compared acceptance and commitment therapy (ACT) and traditional cognitive behavior therapy (tCBT) self-help books for social anxiety, a common concern with notable barriers to treatment seeking. Methods: A sample of college students (n = 102) with social anxiety was randomly assigned to use one of the two self-help books over eight weeks. Results: Improvements were observed in both conditions across all outcomes (social anxiety, general well-being, and social functioning) as well as potential processes of change (cognitive fusion, appraisals of social concerns, and progress toward personal values). Few differences were observed between conditions. Changes in general cognitive fusion consistently predicted outcomes at posttreatment, and anxiety-specific cognitive fusion and concern about negative social interactions also predicted some later outcomes. Conclusions: Use of self-help books to address social anxiety in college students is promising, and addressing cognitive fusion appears to be important

Pilot Evaluation of the Stop, Breathe & Think Mindfulness App for Student Clients on a College Counseling Center Waitlist

Objectives: College counseling centers face significant challenges meeting the mental health needs of their students and waitlists are common. Mobile apps offer a promising solution to increase access to resources while students wait for services. Methods: This pilot randomized controlled trial evaluated the feasibility and acceptability of a publicly available mindfulness app. Students on a counseling center waitlist (n=23) were randomized to use the app or not, with assessments completed over four weeks. Results: Recruitment over three semesters was slow, leading to an underpowered trial. Participants reported high satisfaction and moderate app usage. Very preliminary support was found for potential app efficacy relative to the control condition, particularly for depression, anxiety, and overall distress. Weaker, mixed effects were found for mindfulness and values processes. Conclusions: Overall, these results provide mixed findings suggesting the potential benefits, but also challenges in using a mindfulness app for students waiting to receive counseling services

Effects of Cognitive Restructuring and Defusion for Coping with Difficult Thoughts in a Predominantly White Female College Student Sample

Background: Understanding how cognitive processes are naturally used by untrained individuals in the moment to cope with difficult thoughts may help inform effective and efficient interventions. Methods: This study investigated self-reported naturalistic use of two evidence-based processes, cognitive restructuring and cognitive defusion, in an untrained, predominantly White female college student sample (n = 194) through ecological momentary assessments over seven days. Results: Cognitive restructuring and defusion had a large positive relationship. Both processes were also positively associated with increased momentary use of suppression and distraction. Only momentary defusion was associated with decreased rumination and negative affect at the same timepoint, while both defusion and restructuring were associated with positive affect and increased values progress at the same timepoint. Momentary defusion predicted later values progress, but only among those with low distress. Conclusions: Overall, results suggest that both cognitive restructuring and cognitive defusion are used in a nonclinical, untrained population, that both processes are overall beneficial when used in the moment, and that defusion may be particularly relevant to certain aims such as lower rumination or values progress across time points. Replication among clinical and more diverse populations is needed
