Serial Mediation Analysis of Psychological Inflexibility and Daytime Insomnia Rumination in the Relationship Between Dysfunctional Beliefs About Sleep and Insomnia in College Students.

Emerging research suggests that psychological inflexibility may be a factor contributing to the development and maintenance of insomnia. However, less is known about the potential cognitive pathways that may explain this relationship. In this study, we investigated the serial mediating effects of psychological inflexibility and daytime insomnia-related rumination on the association between dysfunctional beliefs and attitudes about sleep (DBAS) and insomnia symptoms. The sample included 490 college students who underwent assessments at two time points over a 1-month period. The results of our mediational tests yielded significant indirect effects, supporting the prediction that psychological inflexibility and daytime insomnia rumination serially mediate the relationship between DBAS and insomnia. The study provides insights into potential mechanisms for insomnia, emphasizing the role of psychological inflexibility in perpetuating maladaptive cognitive processes associated with insomnia. Future researchers should explore other maladaptive responses to insomnia-related concerns and distress, such as worry and safety behaviors, and replicate findings in clinically elevated insomnia samples.

Rethinking Unacceptable Thoughts: Validation of an Expanded Version of the Dimensional Obsessive-Compulsive Scale.

The Dimensional Obsessive-Compulsive Scale (DOCS) is widely used to measure obsessive-compulsive disorder (OCD) severity across four broad symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, symmetry). Despite its proven utility, there is reason to suspect that the unacceptable thoughts subscale conflates different types of unacceptable thoughts that are meaningfully distinct from one another. In the current study, we first evaluated the psychometric properties of a newly developed DOCS violent and/or aggressive thoughts subscale. We then examined the factor structure, psychometric properties, and diagnostic sensitivity of a seven-factor version of the DOCS that includes the four original DOCS subscales and three more-specific versions of the unacceptable thoughts scale (i.e., sexually intrusive thoughts, violent and/or aggressive thoughts, and scrupulous or religious thoughts). The sample included 329 residential and intensive outpatients, the majority of which had a diagnosis of OCD (75.2%). The new unacceptable thoughts subscales demonstrated convergent and discriminant validity with unique associations between the subscales and depression, suicide, and perceived threat from emotions that were not present in the broader unacceptable thoughts subscale. The seven-factor version of the DOCS demonstrated slightly lower levels of diagnostic sensitivity than the original DOCS. Thus, the four-factor version of the DOCS is recommended for screening purposes. A score of 40 or higher on the seven-factor version of the DOCS best predicted a diagnosis of OCD. Overall, the three additional unacceptable thoughts subscales appear to be distinct factors that have potential value in research and clinical settings.

Sociodemographic representation in randomized controlled trials for anxiety-related disorders in the U.S.: A systematic review (1993-2023).

Cognitive behavioral therapies have been identified as evidence-based treatments for anxiety-related disorders. However, data supporting the effectiveness of these treatments have been largely collected from participants with majoritized identities, potentially limiting the extent to which they can be considered "evidence-based" for clients from minoritized groups. The current review examined sociodemographic representation and quality of sociodemographic reporting in randomized controlled trials for anxiety-related disorders in the U.S. between 1993 and 2023. We conducted a systematic literature review of U.S.-based randomized controlled trials of cognitive behavioral therapies for anxiety-related disorders, extracted data on sociodemographic variables, and rated quality of reporting. Data from 55 eligible studies (N = 4492) indicated that white and female identities were overrepresented relative to the U.S. population, with variables like disability status, sexual orientation, and religious identification consistently ignored. In addition, quality of reporting was generally poor (mean = 3.6 out of 10), with many studies failing to account for demographic variables in their analyses or description of study limitations. Publication year, sample size, and NIH funding status did not significantly predict gender representation (% women), ethnoracial representation (% white), or quality of reporting. These findings underscore the importance of critically evaluating to whom "evidence-based" treatments apply and increasing diversity of clinical samples, to ensure that evidence-based treatments are inclusive. Recommendations for future research, clinical implications, and limitations are discussed.

Online process-based training for perfectionism: A randomized trial.

Process-based therapy (PBT) is model of psychotherapy designed to improve people's ability to use a variety of skills from evidence-based treatments to match environmental needs and personal goals in the moment. This randomized trial tested the effect of an online self-help intervention modeled after PBT principles for participants with perfectionism (N = 77). The intervention comprised two four-session trainings teaching skills from different evidence-based treatments (e.g., cognitive-behavioral therapy, acceptance and commitment therapy) and targeting cognitive and motivational processes: (1) cognitive training and (2) motivational training respectively. Participants completed 17 assessments throughout the intervention and at 3- and 6-month follow-up. Results indicated that the full intervention led to improvement in perfectionism, self-compassion, psychological distress, and cognitive skills targeted by the cognitive intervention (e.g., cognitive defusion; absolute ßs = 0.02 to 0.66). In addition, the second four-session training (i.e., training after first four-session training) was associated with improvements in perfectionism, self-compassion, quality of life, and psychological distress (absolute ßs = 0.09 to 2.90), suggesting it had incremental benefit. Whereas the cognitive training appeared to specifically impact cognitive processes, the motivational training increased both cognitive and motivational processes. These findings provide initial support for the feasibility and efficacy of a process-based approach, because they show that participants can benefit from learning skills from different orientations and applying them with reference to their goals. However, specific aspects of the PBT model, including whether interventions can precisely improve targeted skills, still need to be empirically tested in larger and more diverse clinical samples.

A systematic review of self-report measures of generalized shame.

OBJECTIVE: Shame is a transdiagnostic emotion of strong clinical and research interest. Yet, there is a lack of consensus on the definition and varying methods employed across self-report measures, potentially affecting our ability to accurately study shame and examine whether clinical interventions to alter shame are effective. This paper offers a systematic review of self-report measures of generalized shame. METHODS: PubMed, PsycInfo, and Web of Science were searched. Studies were included when they were available in English and the primary aim was to evaluate measurement properties of scales or subscales designed to measure generalized shame in adults. RESULTS: Thirty-six papers examining 19 scales were identified, with measures of trait shame more common than state shame. Construct validity, internal consistency, and structural validity were relative strengths. Development and content validity studies were lacking and suffered from low methodological quality. CONCLUSIONS: All measures evaluated needed additional research to meet criteria for recommended use.

The Association among Blood Pressure, Blood Pressure Medications, and Glaucoma in a Nationwide Electronic Health Records Database.

PURPOSE: To measure the association among blood pressure (BP), BP medications, and glaucoma using the All of Us Research Program database. DESIGN: A retrospective, longitudinal cohort study leveraging a national electronic health record (EHR) database administered by the National Institutes of Health. PARTICIPANTS: Eye patients in the All of Us Research Program database with at least 15 months of follow-up and 1 BP measurement. METHODS: Univariable and multivariable Cox regression models predicted the risk of developing incident open-angle glaucoma (OAG). Mean arterial pressure (MAP) and the number of BP medication classes were entered as time-varying predictors to account for changes over time. MAIN OUTCOME MEASURES: The risk of developing incident OAG, as defined by billing diagnosis codes. RESULTS: Of 20 815 eligible eye patients who qualified for this study, 462 developed OAG. Low BP (MAP < 83.0 mmHg) was associated with increased risk of developing OAG (hazard ratio [HR], 1.32; 95% confidence interval [CI], 1.04-1.67). High BP (MAP > 101.3 mmHg) and the number of BP medication classes were not associated with OAG after adjustment for covariates. Other risk factors associated with OAG included being Black (HR, 3.31, 95% CI, 2.63-4.17), Hispanic or Latino (HR, 2.53, 95% CI, 1.94-3.28), Asian (HR, 2.22, 95% CI, 1.24-3.97), older in age (80+ years, HR, 20.1, 95% CI, 9.10-44.5), and diabetic (HR, 1.32, 95% CI, 1.04-1.67). Female gender was associated with decreased hazard of developing OAG (HR, 0.66, 95% CI, 0.55-0.80). No significant interaction was observed between MAP and the number of BP medications on the risk of developing OAG. CONCLUSIONS: We found that low BP is associated with increased risk of developing OAG in a national longitudinal EHR database. We did not find evidence supporting a differential effect of medically treated and untreated low BP. This study adds to the body of literature implicating vascular dysregulation as a potential etiology for the development of OAG, particularly emphasizing the lack of influence of BP medications on this relationship.

Impact of Early COVID-19 Pandemic on Common Ophthalmic Procedures Volumes: A US Claims-Based Analysis.

PURPOSE: The COVID-19 pandemic has had a profound effect on the delivery of healthcare in the United States and globally. The aim of this study was to evaluate the impact of COVID-19 on common ophthalmic procedure utilization and normalization to pre-pandemic daily rates. METHODS: Leveraging a national database, Clinformatics™ DataMart (OptumInsight, Eden Prairie, MN), procedure frequencies and daily averages, defined by Current Procedural Terminology codes, of common elective and non-elective procedures within multiple ophthalmology sub-specialties were calculated. Interrupted time-series analysis with a Poisson regression model and smooth spline functions was used to model trends in pre-COVID-19 (January 1, 2018-February 29, 2020) and COVID-19 (March 1, 2020-June 30, 2020) periods. RESULTS: Of 3,583,231 procedures in the study period, 339,607 occurred during the early COVID-19 time period. Anti-vascular endothelial growth factor injections (44,412 to 39,774, RR 1.01, CI 0.99-1.02; p = .212), retinal detachment repairs (1,290 to 1,086, RR 1.07, CI 0.99-1.15; p = .103), and glaucoma drainage implants/trabeculectomies (706 to 487, RR 0.93, CI 0.83-1.04; p = .200) remained stable. Cataract surgery (61,421 to 33,054, RR 0.77; CI 0.76-0.78; p < .001), laser peripheral iridotomy (1,875 to 890, RR 0.82, CI 0.76-0.88; p < .001), laser trabeculoplasty (2,680 to 1,753, RR 0.79, CI 0.74-0.84; p < .001), and blepharoplasty (1,522 to 797, RR 0.71, CI 0.66-0.77; p < .001) all declined significantly. All procedures except laser iridotomy returned to pre-COVID19 rates by June 2020. CONCLUSION: Most ophthalmic procedures that significantly declined during the COVID-19 pandemic were elective procedures. Among these, the majority returned to 2019 daily averages by June 2020.

The insulo-opercular cortex encodes food-specific content under controlled and naturalistic conditions.

The insulo-opercular network functions critically not only in encoding taste, but also in guiding behavior based on anticipated food availability. However, there remains no direct measurement of insulo-opercular activity when humans anticipate taste. Here, we collect direct, intracranial recordings during a food task that elicits anticipatory and consummatory taste responses, and during ad libitum consumption of meals. While cue-specific high-frequency broadband (70-170 Hz) activity predominant in the left posterior insula is selective for taste-neutral cues, sparse cue-specific regions in the anterior insula are selective for palatable cues. Latency analysis reveals this insular activity is preceded by non-discriminatory activity in the frontal operculum. During ad libitum meal consumption, time-locked high-frequency broadband activity at the time of food intake discriminates food types and is associated with cue-specific activity during the task. These findings reveal spatiotemporally-specific activity in the human insulo-opercular cortex that underlies anticipatory evaluation of food across both controlled and naturalistic settings.

Is perfectionism always unhealthy? Examining the moderating effects of psychological flexibility and self-compassion.

OBJECTIVE: Perfectionism is generally associated with worse mental health outcomes, though evidence suggests elements of it may be helpful. In light of these findings, we examined whether psychological skills like psychological flexibility and self-compassion moderated the relationship between perfectionism and wellbeing (i.e., quality of life, symptom impairment, and psychological distress). METHODS: Undergraduate students (N = 677) completed self-report measures. RESULTS: A latent profile analysis identified three perfectionism groups (low, average, and high) based on four perfectionism subscales: concern over mistakes, need for approval, rumination, and striving for excellence. Generally, we found that psychological flexibility and/or self-compassion buffered the impact of average and high perfectionism on quality of life and symptom impairment. CONCLUSION: Our results support the utility of practicing psychological flexibility and/or self-compassion for people with average and high levels of perfectionism. Limitations include using a cross-sectional design and nonclinical sample.

Anticipatory human subthalamic area beta-band power responses to dissociable tastes correlate with weight gain.

The availability of enticing sweet, fatty tastes is prevalent in the modern diet and contribute to overeating and obesity. In animal models, the subthalamic area plays a role in mediating appetitive and consummatory feeding behaviors, however, its role in human feeding is unknown. We used intraoperative, subthalamic field potential recordings while participants (n = 5) engaged in a task designed to provoke responses of taste anticipation and receipt. Decreased subthalamic beta-band (15-30 Hz) power responses were observed for both sweet-fat and neutral tastes. Anticipatory responses to taste-neutral cues started with an immediate decrease in beta-band power from baseline followed by an early beta-band rebound above baseline. On the contrary, anticipatory responses to sweet-fat were characterized by a greater and sustained decrease in beta-band power. These activity patterns were topographically specific to the subthalamic nucleus and substantia nigra. Further, a neural network trained on this beta-band power signal accurately predicted (AUC ≥ 74%) single trials corresponding to either taste. Finally, the magnitude of the beta-band rebound for a neutral taste was associated with increased body mass index after starting deep brain stimulation therapy. We provide preliminary evidence of discriminatory taste encoding within the subthalamic area associated with control mechanisms that mediate appetitive and consummatory behaviors.

Family accommodation in Chinese individuals with obsessive-compulsive disorder.

Family accommodation is a common, treatment-relevant construct related to obsessive-compulsive disorder (OCD) severity and treatment outcome. This initial study examined the nature, incidence, and clinical correlates of family accommodation in Chinese adults with OCD and their relative or person in a close relationship. One hundred four outpatients diagnosed with OCD completed self-report measures of obsessive-compulsive, anxiety, and depression symptoms. Additionally, the individuals with OCD and a relative completed a measure of family accommodation and impairment. Patient-reports of family accommodation were significantly correlated with OCD symptomology and severity. A multiple linear regression indicated that OCD symptomology was a significant predictor of family accommodation, but anxiety, stress, and depression were not. In addition, the current Chinese sample demonstrated greater levels of family accommodation than previous English-speaking samples. Potential explanations and implications of the high levels of reported family accommodation are discussed. Family accommodation could play a significant role in OCD development and/or maintenance in China. Future research considerations are discussed.

The Obsessive-Compulsive Inventory-Revised: Replication of the psychometric properties in China.

The aim of this study is to replicate the findings from previous research about the psychometric properties of the Mandarin Chinese version of the Obsessive-Compulsive Inventory-Revised (OCI-R), which assesses the presence of symptoms obsessive-compulsive disorder and the distress associated with those symptoms. The final clinical sample included 80 participants from multiple psychiatric outpatient clinics in China. Participants completed the following questionnaires: the OCI-R, the Depression, Anxiety, and Stress Scale (DASS-21), the Yale-Brown Obsessive-Compulsive Scale-II (Y-BOCS-II), and the Clinical Global Impressions Scale, Severity (CGI-S). The Mandarin Chinese version of the OCI-R demonstrated good internal consistency for the total scale and each subscale. Good convergent and divergent validity was established. The Mandarin Chinese version of the OCI-R demonstrated good psychometric properties. Further research is needed to examine the factor structure of the Chinese version of the OCI-R and the extent to which it aligns with the original version.

Obsessive compulsive disorder and thought action fusion: Relationships with eating disorder outcomes.

Obsessive Compulsive Disorder (OCD) is among the most common psychiatric comorbidities with eating disorders (EDs) and most studies have only examined this relationship at a diagnostic level. More research is needed to determine whether specific symptom domains and cognitive patterns commonly observed in OCD are most salient among individuals with clinically significant EDs, and whether these symptoms appear to change and/or influence treatment outcomes. Thought Action Fusion (TAF) is one cognitive pattern that may underlie OCD-ED comorbidity. The current study assessed 112 adolescent and adult female patients at a residential ED treatment facility on levels of ED severity, OCD symptom severity, and TAF at pre- and post-treatment. All OCD symptom dimensions were positively correlated with ED severity at pretreatment, with Obsessing, Neutralizing and Ordering OCD symptoms being most elevated. TAF was also positively correlated with ED severity at pre-treatment, and higher levels of TAF at pretreatment significantly predicted greater ED severity at post-treatment after controlling for all other OCD symptoms. Improvements in TAF specific to thoughts about others also predicted improvements in ED severity after controlling for changes in OCD symptoms. Clinically, these results indicate that efforts targeting specific OCD symptom dimensions and TAF in addition to ED-focused treatment as usual may be beneficial for enhancing overall treatment outcomes.

Parent-led Behavioral Intervention for a Treatment-refusing Adult With Obsessive-Compulsive Disorder With Poor Insight and Extreme Family Accommodation.

Obsessive-compulsive disorder (OCD) with poor insight can contribute to the refusal to receive treatment, leaving the burden of care on parents or other caregivers. The case presented here involved a young adult with OCD with delusional levels of insight paired with extreme family-accommodating behaviors that had resulted in impaired quality of life and functioning for the young adult and his parents. A parent-led behavioral intervention [The Supportive Parenting for Anxious Childhood Emotions (SPACE)] that was developed for children with anxiety was adapted and utilized for a young adult with severe OCD. The case presents a treatment option for parents and caregivers of individuals with OCD who refuse treatment.

Effects of Acceptance and Commitment Therapy on Impulsive Decision-Making.

This study examined the transdiagnostic effect of acceptance and commitment therapy (ACT) on impulsive decision-making in a community sample. A total of 40 adults were randomized to eight individual sessions of ACT or an inactive control. Participants completed pre-, mid-, and post-assessments for psychological symptoms; overall behavior change; valued living; delay discounting; psychological flexibility; and distress tolerance. Data were analyzed with multilevel modeling of growth curves. Significant interaction effects of time and condition were observed for psychological flexibility, distress tolerance, psychological symptoms, and the obstruction subscale of valued living. No significant interaction effect was found for two delay discounting tasks nor the progress subscale of valued living. The ACT condition had a significantly larger reduction of problem behavior at post-assessment. The results support use of ACT as a transdiagnostic treatment for impulsive behaviors. The lack of change in delay discounting contrasts previous research.

Acceptance and Commitment Therapy for Trichotillomania: A Randomized Controlled Trial of Adults and Adolescents.

The purpose of this study was to examine acceptance and commitment therapy (ACT) as a standalone treatment for trichotillomania in a randomized controlled trial of adults and adolescents. Participants consisted of a community sample of treatment seeking adults and adolescents with trichotillomania. Of the eligible 39 participants randomized into treatment and waitlist groups, 25 completed treatment and were included in the final analysis. Treatment consisted of a 10-session ACT protocol. Multiple mixed models repeated measures analyses were utilized to evaluate changes in trichotillomania symptom severity, daily number of hairs pulled and urges experienced, and experiential avoidance from pretreatment to posttreatment. Findings indicated significant changes in symptom severity and daily hairs pulled, but not daily urges experienced or psychological flexibility. However, psychological flexibility saw a 24.5% decrease in the treatment group and reduced from clinical to subclinical levels on average. This study suggests that ACT alone is an effective treatment for adults and adolescents with trichotillomania. Outcomes appear to be similar to trials that combined ACT and habit reversal training (HRT).

Acceptance and commitment therapy for a case of scrupulosity-related obsessive-compulsive disorder.

Acceptance and commitment therapy (ACT) is a modern form of cognitive behavior therapy (CBT) with growing support for treating obsessive-compulsive disorder (OCD). We present a case wherein a client presented with scrupulosity-related OCD. We briefly review scrupulosity, explain the theory behind ACT, and present a case, the treatment process, and desired outcomes. Exposure and response prevention (ERP) is described from an ACT perspective and discussed as an option for people with OCD who may be reluctant to engage in more traditional forms of ERP.

A meta-analysis of dropout rates in acceptance and commitment therapy.

Many psychotherapies, including cognitive behavioral therapy and acceptance and commitment therapy (ACT), have been found to be effective interventions for a range of psychological and behavioral health concerns. Another aspect of treatment utility to consider is dropout, as interventions only work if clients are engaged in them. To date, no research has used meta-analytic methods to examine dropout in ACT. Thus, the objectives of the present meta-analysis were to (1) determine the aggregate dropout rate for ACT in randomized controlled trials, (2) compare dropout rates in ACT to those in other psychotherapies, and (3) identify potential moderators of dropout in ACT. Our literature search yielded 68 studies, representing 4,729 participants. The weighted mean dropout rates in ACT exclusive conditions and ACT inclusive conditions (i.e., those that included an ACT intervention) were 15.8% (95% CI: 11.9%, 20.1%) and 16.0% (95% CI: 12.5%, 19.8%), respectively. ACT dropout rates were not significantly different from those of established psychological treatments. In addition, dropout rates did not vary by client characteristics or study methodological quality. However, master's-level clinicians/therapists (weighted mean = 29.9%, CI: 17.6%, 43.8%) were associated with higher dropout than psychologists (weighted mean = 12.4%, 95% CI: 6.7%, 19.4%). More research on manipulable, process variables that influence dropout is needed.

Increasing body image flexibility in a residential eating disorder facility: Correlates with symptom improvement.

OBJECTIVE: The purpose of this study was to examine the effects of changes in body image psychological flexibility over the course of treatment on various outcome variables. METHOD: Participants included 103 female, residential patients diagnosed with an eating disorder. Pretreatment and posttreatment data were collected that examined body image psychological flexibility, general psychological flexibility, symptom severity, and other outcome variables. RESULTS: Changes in body image psychological flexibility significantly predicted changes in all outcome measures except for obsessive-compulsive symptoms after controlling for body mass index, depression, and anxiety. Additionally, these results were maintained after controlling for general psychological flexibility, contributing to the incremental validity of the BI-AAQ. DISCUSSION: This study suggests that changes in body image psychological flexibility meaningfully predict changes in various treatment outcomes of interest, including eating disorder risk, quality of life, and general mental health. Findings indicate that body image psychological flexibility might be a viable target for eating disorder treatment.

Need to screen for clinical levels of OCD? Four questions are the key.

The aim of this study was to investigate a new measure, the Wetterneck-Hart OCD Screener (WHOS), as a self-report screening tool for obsessive-compulsive disorder (OCD). The authors examined relationships between the WHOS and severity scores of OCD measures taken via three methods of data collection: online, at OCD consumer conferences, and from an intensive, residential OCD program. Severity measures included the Yale-Brown Obsessive-Compulsive Scale-Self Report (Y-BOCS-SR), the Dimensional Obsessive-Compulsive Scale (DOCS), and the Obsessive-Compulsive Inventory-Revised (OCI-R). A total of 525 participants took the measures: 298 from online websites, 100 from OCD conferences, and 127 from a residential OCD program. Significant differences were found between the OCD and non-OCD groups classified by the WHOS for each of the OCD severity measures. The authors conclude that the WHOS is useful in predicting the presence of clinically severe OCD symptoms and could be employed in clinical and research endeavors.
