Multilevel cultural evolution: From new theory to practical applications.

Evolutionary science has led to many practical applications of genetic evolution but few practical uses of cultural evolution. This is because the entire study of evolution was gene centric for most of the 20th century, relegating the study and application of human cultural change to other disciplines. The formal study of human cultural evolution began in the 1970s and has matured to the point of deriving practical applications. We provide an overview of these developments and examples for the topic areas of complex systems science and engineering, economics and business, mental health and well-being, and global change efforts.

Relationship between outcomes and processes in patients with chronic low back pain plus depressive symptoms: idiographic analyses within a randomized controlled trial.

OBJECTIVE: This study explored the extent to which within-patient changes in processes targeted in Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD) are associated with changes within-patient in pain intensity and depressed mood and evaluated the extent that process-outcome relationships differed between patients. METHODS: An idiographic analysis embedded within a randomized controlled trial comparing ACT, BATD, and treatment-as-usual (TAU) was conducted to examine the strength of the relationship between outcomes and process variables in patients with chronic low back pain (CLBP) plus depressive symptoms. Based on data from ecological momentary assessment in patients (n = 82), the level of heterogeneity and the pooled effects of these relationships during the intervention period (70 days) were explored. RESULTS: Overall, a high level of heterogeneity was identified in the relationship between pain intensity or depressed mood and psychological inflexibility or behavioral activation. Individual differences in the relationships between outcomes and process variables were identified in individual people during the intervention period. These individual differences appear independent of the group (ACT, BATD, and TAU) and other definable differences (responders/non-responders, completers/non-completers, and clinical depression/non-clinical depression). CONCLUSIONS: These findings suggest the potential utility of personalizing psychological interventions according to the therapeutic needs of these patients.

A method for increasing 3D body scanning's precision: Gryphon and consecutive scanning.

The fashion industry cannot use 3 D Body Scanning to create custom garment patterns because its measurements fail to meet ISO 20685:2010's tolerances. To advance 3 D Body Scanning's precision, we present Gryphon: an algorithm that removes the two most extreme measurements from five body scans; removing potentially erroneous data. We assess Gryphon's precision against current industry practice, determine if consecutive and non-consecutive data capture influences precision, and determine 3 D Body Scanning's inherent imprecision inherent. We analyse 97 participants over 121 industry-standard measurements for consecutive and non-consecutive data-capture through MANOVA statistical analysis. Under current industry practice, only one measurement meets ISO 20685. However, under Gryphon and consecutive scanning, 97.5% of measurements meet ISO 20685. We also prove that the body's in-scan movement does not affect reliability. Ultimately, we offer the fashion industry, ergonomists, and practitioners an accessible method to increase 3 D Body Scanning's precision at a level unavailable under previous methods. Practitioner Summary: Ergonomists need precise data, yet we prove 0% of 3 D Body Scanning's measurements meet ISO 20685's tolerances. Our analysis of 97 participants scans, shows consecutive scanning is necessary to achieve data suitable for anthropometric applications. We develop the Gryphon process with consecutive scanning, making 97.3% of measurements meet ISO 20685.

Assessing the female figure identification technique's reliability as a body shape classification system.

This paper demonstrates the effects of slight differences in measurement definitions on resultant body shape classification. Ergonomic researchers consider the Female Figure Identification Technique (FFIT) a 'gold standard' body shape classification system to describe variation in a population's 3 D profile. Nevertheless, researchers use FFIT without a scientific basis or considering their ergonomic suitability. This paper rigorously evaluates FFIT, focussing on ergonomics, garment construction, and scientific research applications. Through analysing 1,679 3 D Body Scans, we assess the level of agreement between the FFIT's body shape classification when measurements placed following FFIT's or SizeUK's guidance. We establish how different interpretations of FFIT's measurement placement cause the same body to be categorised into different shapes - in up to 40% of cases. FFIT omits shoulder measurements that have little relationship to body shape yet are vital in garment construction. Using FFIT with different datasets and definitions, therefore, leads to inconsistent conclusions about shape differences.

Acceptance and commitment therapy for psychosis: randomised controlled trial.

BACKGROUND: The efficacy of acceptance and commitment therapy (ACT) in psychosis has been reported but not for medication-resistant psychosis. AIMS: To test the efficacy of ACT in a sample of community-residing patients with persisting psychotic symptoms. (Australian New Zealand Clinical Trials Registry: ACTRN12608000210370.) METHOD: The primary outcome was overall mental state at post-therapy (Positive and Negative Syndrome Scale - total); secondary outcomes were psychotic symptom dimensions and functioning. In total, 96 patients were randomised to ACT (n = 49) or befriending (n = 47). Symptom, functioning and process measures were administered at baseline, post-therapy and 6 months later. RESULTS: There was no group difference on overall mental state. In secondary analyses the ACT group showed greater improvement in positive symptoms and hallucination distress at follow-up: Cohen's d = 0.52 (95% CI 0.07-0.98) and 0.65 (95% CI 0.24-1.06), respectively. CONCLUSIONS: Improvements reflected the treatment focus on positive symptoms; however, absence of process-measure changes suggests that the ACT intervention used did not manipulate targeted processes beyond befriending. Symptom-specific therapy refinements, improved investigation of process and attention to cognitive functioning and dose are warranted in future research.

Web-Based Self-Help for Preventing Mental Health Problems in Universities: Comparing Acceptance and Commitment Training to Mental Health Education.

OBJECTIVE: This study sought to test the feasibility of a web-based Acceptance and Commitment Training (ACT) prototype prevention program called ACT on College Life (ACT-CL). METHOD: A sample of 234 university students was randomized to either the ACT-CL website or a mental health education (MHE) website. RESULTS: Findings indicated a lower level of user engagement and satisfaction ratings with the prototype of ACT-CL than the MHE website. There were no significant differences between conditions on outcome measures at post or follow-up. However, statistical trends suggested the MHE condition actually led to greater remission of severe symptoms than the ACT-CL condition among those with severe symptoms at baseline. There were no differences between conditions on ACT process of change measures. Changes in psychological flexibility were predictive of changes in mental health across conditions, but relations dissipated over time. Furthermore, greater engagement in some components of ACT-CL predicted improvements in psychological flexibility, though not on mental health outcomes. CONCLUSIONS: The effects of the ACT-CL program on mental health outcomes and ACT process measures were largely equivalent to those of an education website, although there was a lower level of program engagement with ACT-CL. Findings are discussed in the context of feasibility issues and lessons learned for program revisions.

Examining the role of psychological inflexibility, perspective taking, and empathic concern in generalized prejudice.

Research to-date on generalized prejudice has focused primarily on personality factors. Further work is needed identifying manipulable variables that directly inform antiprejudice interventions. This study examined three such variables: empathic concern, perspective taking, and psychological inflexibility/flexibility with prejudiced thoughts, as a test of the flexible connectedness model. A sample of 604 undergraduate students completed online surveys. A model indicated prejudice measures loaded onto a latent variable of generalized prejudice. In a second model, psychological inflexibility, flexibility, empathic concern, and perspective taking were all significant, independent predictors of generalized prejudice. Psychological inflexibility also predicted prejudice above and beyond personality and general inflexibility variables. Results suggest the three components of the flexible connectedness model may be important targets for prejudice interventions.

The Origin and Evolution of the Behavior Analysis Program at the University of Nevada, Reno.

The origins of the Behavior Analysis program at the University of Nevada, Reno by way of a self-capitalized model through its transition to a more typical graduate program is described. Details of the original proposal to establish the program and the funding model are described. Some of the unusual features of the program executed in this way are discussed, along with problems engendered by the model. Also included is the diversification of faculty interests over time. The status of the program, now, after 25 years of operation, is presented.

Feasibility of an acceptance and commitment therapy adjunctive web-based program for counseling centers.

Web-based adjunctive tools provide a promising method for addressing the challenges college counseling centers face in meeting the mental health needs of students. The current study tested an initial adjunctive prototype based on acceptance and commitment therapy (ACT) in a pre-post open trial with 30 counselors and 82 student clients across 4 counseling centers. Results indicated high ratings of program satisfaction and usability with counselors and students. The majority of students completed at least part of the program. Significant improvements were found across almost all outcome and ACT process measures with student clients. Improvements in student outcomes were predicted by both changes in psychological inflexibility and how often counselors discussed the program with students. Results are discussed in relation to support for and future development of a flexible, adjunctive ACT program for counseling centers.

A randomised controlled trial of acceptance and commitment therapy (ACT) for psychosis: study protocol.

BACKGROUND: Cognitive behavior therapy for psychosis has been a prominent intervention in the psychological treatment of psychosis. It is, however, a challenging therapy to deliver and, in the context of increasingly rigorous trials, recent reviews have tempered initial enthusiasm about its effectiveness in improving clinical outcomes. Acceptance and commitment therapy shows promise as a briefer, more easily implemented therapy but has not yet been rigorously evaluated in the context of psychosis. The purpose of this trial is to evaluate whether Acceptance and Commitment Therapy could reduce the distress and disability associated with psychotic symptoms in a sample of community-residing patients with chronic medication-resistant symptoms. METHODS/DESIGN: This is a single (rater)-blind multi-centre randomised controlled trial comparing Acceptance and Commitment Therapy with an active comparison condition, Befriending. Eligible participants have current residual hallucinations or delusions with associated distress or disability which have been present continuously over the past six months despite therapeutic doses of antipsychotic medication. Following baseline assessment, participants are randomly allocated to treatment condition with blinded, post-treatment assessments conducted at the end of treatment and at 6 months follow-up. The primary outcome is overall mental state as measured using the Positive and Negative Syndrome Scale. Secondary outcomes include preoccupation, conviction, distress and disruption to life associated with symptoms as measured by the Psychotic Symptom Rating Scales, as well as social functioning and service utilisation. The main analyses will be by intention-to-treat using mixed-model repeated measures with non-parametric methods employed if required. The model of change underpinning ACT will be tested using mediation analyses. DISCUSSION: This protocol describes the first randomised controlled trial of Acceptance and commitment therapy in chronic medication-resistant psychosis with an active comparison condition. The rigor of the design will provide an important test of its action and efficacy in this population. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry: ACTRN12608000210370.

Stigma predicts residential treatment length for substance use disorder.

BACKGROUND: Stigma has been suggested as a possible contributor to the high rates of treatment attrition in substance-dependent individuals, but no published empirical studies have examined this association. OBJECTIVES: The present paper assessed the relationship between baseline stigma variables and length of treatment stay in a sample of patients in a residential addictions treatment unit. METHODS: The relationship between baseline stigma variables (self-stigma, enacted stigma, and shame) and length of stay for participants (n=103) in a residential addictions treatment unit was examined. RESULTS: Higher self-stigma predicted longer stay in residential addictions treatment, even after controlling for age, marital status, race, overall mental health, social support, enacted stigma, and internalized shame. However, other stigma variables (i.e. internalized shame, stigma-related rejection) did not reliably predict length of treatment stay. CONCLUSION: These results are consistent with other findings suggesting that people with higher self-stigma may have a lowered sense of self-efficacy and heightened fear of being stigmatized and therefore retreat into more protected settings such as residential treatment, potentially resulting in higher treatment costs. Specialized clinical interventions may be necessary to help participants cope with reduced self-efficacy and fear of being stigmatized.

Evolving the future: toward a science of intentional change.

Humans possess great capacity for behavioral and cultural change, but our ability to manage change is still limited. This article has two major objectives: first, to sketch a basic science of intentional change centered on evolution; second, to provide examples of intentional behavioral and cultural change from the applied behavioral sciences, which are largely unknown to the basic sciences community. All species have evolved mechanisms of phenotypic plasticity that enable them to respond adaptively to their environments. Some mechanisms of phenotypic plasticity count as evolutionary processes in their own right. The human capacity for symbolic thought provides an inheritance system having the same kind of combinatorial diversity as does genetic recombination and antibody formation. Taking these propositions seriously allows an integration of major traditions within the basic behavioral sciences, such as behaviorism, social constructivism, social psychology, cognitive psychology, and evolutionary psychology, which are often isolated and even conceptualized as opposed to one another. The applied behavioral sciences include well-validated examples of successfully managing behavioral and cultural change at scales ranging from individuals to small groups to large populations. However, these examples are largely unknown beyond their disciplinary boundaries, for lack of a unifying theoretical framework. Viewed from an evolutionary perspective, they are examples of managing evolved mechanisms of phenotypic plasticity, including open-ended processes of variation and selection. Once the many branches of the basic and applied behavioral sciences become conceptually unified, we are closer to a science of intentional change than one might think.

A Process-Based Approach to Transtheoretical Clinical Research and Training.

Background: The science and practice of psychopathology and psychological intervention of today is more like an island archipelago than it is a single land mass, and connections between different traditions are both limited and fraught with misunderstanding. Method: Our analysis and solution to the problem is process-based therapy (PBT). PBT defines psychopathology as failed adaptation processes to a given context. Therapy involves adaptation through context-dependent or context-altering applications of biopsychosocial strategies that allows a goal to be met. Results: This coherent approach to more transtheoretical and integrative concepts of clinical training and practice provides a firm foundation by targeting biopsychosocial processes of change, analyzing these processes using an idiographic complex network analytic approach, and organizing findings on the intellectual agora of multi-dimensional and multi-level evolutionary science. Conclusion: PBT is a new empirical form of functional analysis, resulting in interventions and trainings that are built on elements or kernels of direct relevance to client's specific needs. In PBT, case formulation continues as long as treatment persists.

Psychological flexibility and cognitive-affective processes in young adults' daily lives.

Psychological flexibility plays a crucial role in how young adults adapt to their evolving cognitive and emotional landscapes. Our study investigated a core aspect of psychological flexibility in young adults: adaptive variability and maladaptive rigidity in the capacity for behavior change. We examined the interplay of these elements with cognitive-affective processes within a dynamic network, uncovering their manifestation in everyday life. Through an Ecological Momentary Assessment design, we collected intensive longitudinal data over 3 weeks from 114 young adults ages 19 to 32. Using a dynamic network approach, we assessed the temporal dynamics and individual variability in flexibility in relation to cognitive-affective processes in this sample. Rigidity exhibited the strongest directed association with other variables in the temporal network as well as highest strength centrality, demonstrating particularly strong associations to other variables in the contemporaneous network. In conclusion, the results of this study suggest that rigidity in young adults is associated with negative affect and cognitions at the same time point and the immediate future.

When Average Isn't Good Enough: Identifying Meaningful Subgroups in Clinical Data.

Background: Clinical data are usually analyzed with the assumption that knowledge gathered from group averages applies to the individual. Doing so potentially obscures patients with meaningfully different trajectories of therapeutic change. Needed are "idionomic" methods that first examine idiographic patterns before nomothetic generalizations are made. The objective of this paper is to test whether such an idionomic method leads to different clinical conclusions. Methods: 51 patients completed weekly process measures and symptom severity over a period of eight weeks. Change trajectories were analyzed using a nomothetic approach and an idiographic approach with bottom-up clustering of similar individuals. The outcome was patients' well-being at post-treatment. Results: Individuals differed in the extent that underlying processes were linked to symptoms. Average trend lines did not represent the intraindividual changes well. The idionomic approach readily identified subgroups of patients that differentially predicted distal outcomes (well-being). Conclusions: Relying exclusively on average results may lead to an oversight of intraindividual pathways. Characterizing data first using idiographic approaches led to more refined conclusions, which is clinically useful, scientifically rigorous, and may help advance individualized psychotherapy approaches.

Development and preliminary randomized controlled trial of a distress tolerance treatment for smokers with a history of early lapse.

INTRODUCTION: An inability to tolerate distress is a significant predictor of early smoking lapse following a cessation attempt. We conducted a preliminary randomized controlled trial to compare a distress tolerance (DT) treatment that incorporated elements of exposure-based therapies and Acceptance and Commitment Therapy to standard smoking cessation treatment (ST). METHODS: Smokers with a history of early lapse in prior quit attempts received either DT (N = 27; 9 2-hr group and 6 50-min individual sessions) or ST (N = 22; 6 90-min group and 1 20-min individual session), plus 8 weeks of transdermal nicotine patch. RESULTS: At the end of behavioral treatment, odds of abstinence among participants receiving DT were 6.46 times greater than among participants receiving ST (66.7% vs. 31.8%), equivalent to a medium- to large-effect size. Odds of abstinence for DT were still 1.73 times greater at 8 weeks, corresponding to a small- to medium-effect size, although neither this difference nor those at 13 and 26 weeks were statistically significant. Furthermore, of those who lapsed to smoking during the first week postquit, DT participants had more than 4 times greater odds of abstinence than ST participants at the end of treatment. Relative to ST, DT participants also reported a larger decrease in experiential avoidance, a hypothesized DT treatment mediator, prior to quit day. The trajectory of negative mood and withdrawal symptoms in DT differed from ST and was largely consistent with hypotheses. CONCLUSIONS: Reasons for the decrease in abstinence in DT after treatment discontinuation and suggestions for future research are discussed.

A biphasic relational approach to the evolution of human consciousness: Un enfoque relacional bifásico para la evolución de la conciencia humana.

Background/objective: Human consciousness is arguably unique, and its features are hard to explain. Continuous and discrete accounts of consciousness are commonly viewed as incompatible, but both have limitations. Continuous accounts cannot readily account for what appears to be unique about human consciousness; discrete accounts have a hard time explaining how human consciousness could have evolved. The present position paper shows how both continuous and discontinuously elements can be combined. Method: A biphasic model is constructed by unifying complex systems theory, the evolution of symbolic reasoning as a relational extension of human cooperation, and evolutionary science. The application of this approach to modern views of consciousness is then explored. Results: Our analysis suggests that human consciousness may be viewed as a discontinuous event, that emerged from continuous foundations. This biphasic account contains processes that can be targeted clinically. For example, developmentally delayed children with problems in consciousness may be helped by targeting the processes the present account suggests are important at different levels of complexity. Conclusions: This biphasic relational approach fits with the evolutionary record and with data on human cognitive development. It may be useful in guiding clinical intervention.

The Idionomic Future of Cognitive Behavioral Therapy: What Stands Out From Criticisms of ACT Development.

The present special section critical of Acceptance and Commitment Therapy or Training (ACT in either case) and its basis in psychological flexibility, relational frame theory, functional contextualism, and contextual behavioral science (CBS) contains both worthwhile criticisms and fundamental misunderstandings. Noting the important historical role that behavior analysis has played in the cognitive behavioral therapy (CBT) tradition, we argue that CBS as a modern face of behavior analytic thinking has a potentially important positive role to play in CBT going forward. We clarify functional contextualism and its link to ethical behavior, attempting to clear up misunderstandings that could seriously undermine genuine scientific conversations. We then examine the limits of using syndromes and protocols as a basis for further developing models and methods; the role of measurement and processes of change in driving progress toward more personalized interventions; how pragmatically useful concepts can help basic science inform practice; how both small- and large-scale studies can contribute to scientific progress; and how all these strands can be pulled together to benefit humanity. In each area, we argue that further progress will require major modifications in our traditional approaches to such areas as psychometrics, the conduct of randomized trials, the analysis of findings using traditional normative statistics, and the use of data from diverse cultures and marginalized populations. There have been multiple generational shifts in our field's history, and a similar shift appears to be taking place once again.

An Open-Source Relational Network Derivation Script in R for Modeling and Visualizing Complex Behavior for Scientists and Practitioners.

Relational models of cognition provide parsimonious and actionable models of generative behavior witnessed in humans. They also inform many current computational analogs of cognition including Deep Neural Networks, Reinforcement Learning algorithms, Self-Organizing Maps, as well as blended architectures that are outperforming traditional semantic models. The black box nature of these computer models artificially limits scientific and applied progress and human computer interaction. This paper presents a first in the field attempt to model relational processes using logical derivation scripts and network graph visualizations written in the open-source R language. These tools are presented as a way for researchers and practitioners to begin to explore more complex relational models in a manner that can advance the theory and empirical science, as well as prepare the field for future collaborations with advanced computational models of cognition.

A process-based approach to cognitive behavioral therapy: A theory-based case illustration.

Despite the significant contribution of cognitive-behavioral therapy to effective treatment options for specific syndromes, treatment progress has been stagnating, with response rates plateauing over the past several years. This stagnation has led clinical researchers to call for an approach that instead focuses on processes of change and the individual in their particular context. Process-based therapy (PBT) is a general approach representing a model of models, grounded in evolution science, with an emphasis on idiographic methods, network models of case conceptualization, and enhancing wellbeing. In this paper, we describe the theory underlying PBT and present a case study for how to apply PBT tools and principles to deliver process-informed and person-centered evidence-based treatment. In addition, we discuss lessons learned from our case and provide suggestions for future considerations when implementing PBT in clinical settings.
