The acceptance and commitment therapy matrix mobile app: A pilot randomized trial on health behaviors

Mobile apps provide a promising format for delivering acceptance and commitment therapy (ACT) to improve diet/exercise. This pilot trial evaluated a novel ACT-based app for health behaviors based on the matrix approach. A sample of 23 community adults were randomly assigned to use the app for two weeks or to a waitlist condition. Findings indicated a high degree of satisfaction with the app and acceptable adherence. Although the intent-to-treat sample indicated few intervention effects, when focusing on program engagers only, health behaviors significantly improved in the app condition relative to waitlist. There were no differences between conditions on valued action or experiential avoidance. However, the rate of valued actions increased over days using the app. This was moderated by baseline values and experiential avoidance, suggesting those more psychologically flexible benefit more from the matrix app. An ACT matrix app appears promising for improving health behaviors, but additional revisions and research is needed

Experiential Avoidance and Negative Affect as Predictors of Daily Drinking

People who drink alcohol to cope with negative affect tend to drink more and experience more frequent negative alcohol-related consequences. Experiential avoidance, the tendency to avoid, suppress, or otherwise attempt to control unwanted inner experiences, is a largely pathological process that may help account for how negative affect is linked to increased alcohol consumption. However, research to-date has typically used global, trait-like measures, which limit our understanding of the conditions under which experiential avoidance is problematic. The current study tested both between-person (trait) and within-person (daily) variation in experiential avoidance and negative affect as predictors of solitary and social drinking in a sample of 206 adult drinkers who completed daily diaries for 21 days. Participants higher in trait experiential avoidance drank alone more often, while those higher in trait negative affect consumed greater quantities when drinking alone. Although daily fluctuations in experiential avoidance did not predict solitary drinking, there was a significant interaction between daily experiential avoidance and trait negative affect. For participants high in trait negative affect, greater experiential avoidance on a given day predicted consuming more when drinking alone. For participants low in trait negative affect, greater experiential avoidance on a given day predicted drinking alone more often, but consuming fewer drinks on these occasions. Experiential avoidance did not predict social drinking in any model. Overall, results suggest that a broader tendency to experience negative affect sets the context for experiential avoidance to be linked to more harmful patterns of drinking

Do college students use online self-help? A survey of intentions and use of mental health resources

Online self-help may help increase the reach of mental health services for college students, but little research has examined students’ actual interest/use of these resources. An online survey of 389 college students examined intentions and use of online mental health resources as compared with other support options. Findings indicated the highest intentions/use of informal supports (e.g., parents, friends) for mental health problems and lowest intentions/use for online self-help. However, a subset of students showed a preference for online self-help over other forms of support. Participants were also more likely to request online self-help resources (21%) than in-person therapy resources (9%) when offered these options. Reported barriers were also identified for using mobile apps specifically (e.g., stigma, credibility, privacy). Overall, results suggest mixed findings and relatively low interest for use of online self-help among college students, while highlighting potential barriers that might be addressed to increase engagement

Evaluating an adjunctive mobile app to enhance psychological flexibility in acceptance and commitment therapy

The primary aims of this study were to evaluate the feasibility and potential efficacy of a novel adjunctive mobile app designed to enhance the acquisition, strengthening, and generalization of acceptance and commitment therapy (ACT) skills being taught in therapy. A sample of 14 depressed/anxious clients receiving ACT used the ACT Daily app for two weeks in a pre-post, open trial design. Participants reported a high degree of program satisfaction. Clients significantly improved over the two-week period on depression and anxiety symptoms as well as a range of psychological inflexibility measures. Analyses of mobile app data indicated effects of ACT Daily skill coaching on in-the-moment measures of inflexibility and symptoms, with unique effects found for acceptance and mindfulness. Adjunctive ACT mobile apps appear promising in enhancing therapy effects on psychological inflexibility and outcomes. A tailored skill coaching approach like ACT Daily based on randomly prompted assessments may be especially promising

Examining the feasibility of acceptance and commitment therapy self-help for problematic pornography viewing: Results from a pilot open trial

This pilot study evaluated the feasibility of an acceptance and commitment therapy (ACT) self-help program for problematic pornography viewing (PV). A sample of 19 adults seeking help for problematic PV was recruited in an open trial. Participants reported adequate program acceptability, although only 45% of those completing post-assessment read at least half of the self-help book. Significant improvements on problematic PV and cognitive fusion were found over the 8-week intervention period, with effects sustaining at 8-week follow-up. Participants who read more improved more on PV problems and psychological inflexibility. Overall, an ACT self-help approach appears feasible and potentially efficacious for PV

A Randomized Dismantling Trial of the Open and Engaged Components of Acceptance and Commitment Therapy in an Online Intervention for Distressed College Students

This dismantling trial compared the effects of a full online Acceptance and Commitment Therapy (ACT) intervention to the isolated effects of the Open (i.e., acceptance, cognitive defusion) and Engaged (i.e., values, committed action) components of ACT. A sample of 181 distressed college students were randomized to one of four conditions: a 12-session full ACT website (Full), a version targeting the Open components (Open), a version targeting the Engaged components (Engaged), or waitlist. Participants in active conditions were also randomized to receive phone coaching or just email prompts to increase program adherence. All three ACT conditions significantly improved over time relative to the waitlist condition on the primary outcome of mental health symptoms. The Engaged and Full conditions had greater rates of reliable change on the primary outcome relative to waitlist, but not the Open condition. Similarly, only Engaged and Full conditions improved on positive mental health relative to waitlist. The Full condition had greater improvements on a few ACT process measures relative to Engaged and Open conditions, particularly cognitive fusion. Overall, results indicate targeting only the Open components of ACT was somewhat less effective, and that including both the Open and Engaged components led to greater decreases in cognitive fusion

When Is Experiential Avoidance Harmful in the Moment? Examining Global Experiential Avoidance as a Moderator

Background and Objectives: Although experiential avoidance has been shown to predict a wide range of mental health problems, there has been minimal research to-date on the more immediate effects of engaging in experiential avoidance in the moment or the moderators that predict when it is more or less harmful. Methods: An ecological momentary assessment (EMA) study was conducted with 70 undergraduate students who completed assessments three times a day, over seven days as well as a baseline assessment of global questionnaires. Results: Both greater global experiential avoidance and momentary experiential avoidance independently predicted greater momentary negative affect, lower positive affect, and lower valued action. Global experiential avoidance was also a significant moderator of momentary experiential avoidance such that experiential avoidance in the moment was more strongly related to negative effects among those high in global experiential avoidance. Limitations: Study limitations include a non-clinical student sample and use of unvalidated EMA items. Conclusions: Overall, these results suggest engaging in experiential avoidance in the moment has more negative, immediate effects particularly among those who engage in global, inflexible patterns of experiential avoidance

Web-based Acceptance and Commitment Therapy for Mental Health Problems in College Students: A Randomized Controlled Trial

There are significant challenges in addressing the mental health needs of college students. The current study tested an acceptance and commitment therapy (ACT) web-based self-help program to treat a broad range of psychological problems students struggle with. A sample of 79 college students were randomized to web-based ACT or a waitlist condition, with assessments at baseline and posttreatment. Results indicated adequate acceptability and program engagement for the ACT website. Relative to waitlist, participants receiving ACT improved on overall distress, general anxiety, social anxiety, depression, academic concerns, and positive mental health. There were no between group effects on eating concerns, alcohol use, or hostility or on some key ACT process of change measures. ACT participants improved more on mindful acceptance and obstruction to valued living, both of which mediated treatment outcomes. Results are discussed in the context of lessons learned with the website prototype, and areas for further research are presented

A Psychometric Comparison of Psychological Inflexibility Measures: Discriminant Validity and Item Performance

Psychological inflexibility is a rigid behavioral pattern that interferes with engagement in personally meaningful activities; it is the hypothesized root of suffering in acceptance and commitment therapy (ACT). Thus, the quality of its measurement affects the research, theory, and practice of ACT. The current study aimed to evaluate the discriminant validity and item performance of four measures of psychological inflexibility: the Acceptance and Action Questionnaire—II (AAQ-II), a revised version of the AAC-II (AAQ-3), the Brief Experiential Avoidance Questionnaire (BEAQ), and the Comprehensive assessment of Acceptance and Commitment Therapy processes (CompACT). We analyzed data from community (n = 253), student (n = 261), and treatment-seeking samples (n = 140) using exploratory factor analysis and multigroup graded-response models. The CompACT had the strongest discriminant validity followed by the AAQ-3, whereas items in the CompACT Behavioral Awareness and Valued Action subscales performed most consistently across groups. No single measure emerged as clearly superior to others; rather, appropriate selection of measures depends on the goals and context of assessment. Scientific and clinical implications are discussed

Theoretical uncertainties in sparticle mass predictions from computational tools

We estimate the current theoretical uncertainty in sparticle mass predictions by comparing several state-of-the-art computations within the minimal supersymmetric standard model (MSSM). We find that the theoretical uncertainty is comparable to the expected statistical errors from the Large Hadron Collider (LHC), and significantly larger than those expected from a future e+e- Linear Collider (LC). We quantify the theoretical uncertainty on relevant sparticle observables for both LHC and LC, and show that the value of the error is significantly dependent upon the supersymmetry (SUSY) breaking parameters. We also present the theoretical uncertainty induced in fundamental-scale SUSY breaking parameters when they are fitted from LHC measurements. Two regions of the SUSY parameter space where accurate predictions are particularly difficult are examined in detail: the large tan(beta) and focus point regimes.Comment: 22 pages, 6 figures; comment added pointing out that 2-loop QCD corrections to mt are incorrect in some of the programs investigated.
