Abstract
BACKGROUND Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by heterogeneous symptoms and genetic underpinnings. Recent advancements in genetic and epigenetic research have provided insights into the intricate mechanisms contributing to ASD, influencing both diagnosis and therapeutic strategies.
AIM To explore the genetic architecture of ASD, elucidate mechanistic insights into genetic mutations, and examine gene-environment interactions.
METHODS A comprehensive systematic review was conducted, integrating findings from studies on genetic variations, epigenetic mechanisms (such as DNA methylation and histone modifications), and emerging technologies [including Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9 and single-cell RNA sequencing]. Relevant articles were identified through systematic searches of databases such as PubMed and Google Scholar.
RESULTS Genetic studies have identified numerous risk genes and mutations associated with ASD, yet many cases remain unexplained by known factors, suggesting undiscovered genetic components. Mechanistic insights into how these genetic mutations impact neural development and brain connectivity are still evolving. Epigenetic modifications, particularly DNA methylation and non-coding RNAs, also play significant roles in ASD pathogenesis. Emerging technologies like CRISPR-Cas9 and advanced bioinformatics are advancing our understanding by enabling precise genetic editing and analysis of complex genomic data.
CONCLUSION Continued research into the genetic and epigenetic underpinnings of ASD is crucial for developing personalized and effective treatments. Collaborative efforts integrating multidisciplinary expertise and international collaborations are essential to address the complexity of ASD and translate genetic discoveries into clinical practice. Addressing unresolved questions and ethical considerations surrounding genetic research will pave the way for improved diagnostic tools and targeted therapies, ultimately enhancing outcomes for individuals affected by ASD.

An imagery rescripting based intervention in children and adolescents who endured a negative life event: A pilot study, satisfaction and feasibility survey. J Behav Ther Exp Psychiatry 2024; 84:101957.

Abstract
BACKGROUND AND OBJECTIVES ImRs, a technique targeting distressing mental images, has shown promise in adult psychiatric treatment. Initial research indicates positive outcomes in children, with potential for reducing mental health care burden. This pilot study examined the use of Imagery Rescripting (ImRs) as an intervention for children who have experienced negative life events. We aimed to assess short-term emotional changes, participant satisfaction, and the feasibility of a larger-scale ImRs intervention for children. METHODS We employed a pre-posttest within-group design, and included 35 children (ages 5-18) who experienced negative life events, as well as 12 coaches. ImRs targeted distressing images related to negative events. Measurement tools included Visual Analogue Scales for distress and emotions, along with satisfaction surveys for both children and coaches. The feasibility of a larger-scale study was also explored through a coach questionnaire. RESULTS We found significant short-term improvements for all emotional states, with large effects for anxiety, sadness, and happiness, and a moderate effect for anger. Children reported fair levels of satisfaction with the intervention's acceptability and complexity. Coaches expressed high levels of satisfaction with the intervention as a whole and with its characteristics. Coaches were also strongly motivation for future, more in-depth research. An important limitation of this pilot study was the lack of a control group. In light of the promising results, more extensive studies with diagnostic information, multiple measures, and follow-up assessments are warranted. CONCLUSION Altogether, imagery rescripting based interventions seem a promising venue for children who experienced negative events.

Perceived stress and associations between physical activity, sedentary time, and interstitial glucose in healthy adolescents. Physiol Behav 2024; 283:114617. [PMID: 38889810 PMCID: PMC11246823 DOI: 10.1016/j.physbeh.2024.114617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 05/09/2024] [Accepted: 06/15/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Less moderate to vigorous physical activity (MVPA), more sedentary time (ST), and higher perceived stress are related to type 2 diabetes mellitus (T2DM) occurrence, but observational evidence addressing the interaction of these factors is lacking in youth. This pilot study investigated momentary stress as a moderator in the acute associations of MVPA and ST with subsequent glucose in healthy adolescents. METHODS Participants (N=15, Mage=13.1±1.0 years, 10 girls, 5 with overweight/obesity) simultaneously wore a continuous glucose monitor (CGM), thigh-mounted accelerometer, and reported momentary stress via random ecological momentary assessments (EMA; Time T) for 7-14 days. MVPA and ST (min) were calculated for 60- and 120-minute time windows before each EMA prompt (Time T-1). Mean CGM-measured interstitial glucose (mg/dL) was calculated after each prompt (Mmin=120.0±25.4; Time T+1). Multilevel models assessed whether within-subject MVPA and ST (Time T-1) predicted mean glucose (Time T+1), with momentary stress as a moderator (Time T). RESULTS There were 513 time-matched EMA reports of stress, accelerometer, and CGM data. Momentary stress moderated the effects of MVPA 60 (β=-0.22, p=.001) and 120 min (β=-0.08, p=.02) before the prompt on subsequent glucose levels. When youth spent more time in MVPA than their average and when momentary stress was higher than their average, subsequent glucose was lower. Stress did not moderate associations of ST with glucose (p>.05). CONCLUSIONS Higher momentary stress may interact with higher MVPA to lower subsequent glucose in youth. Accelerometers, EMA, and CGMs can be integrated in future studies to further understand these associations in free-living environments.

Abstract
To provide deeper insights into the relationships between psychopathic traits and utilitarian moral judgment, we studied N = 702 adults using three psychopathy scales: (a) the Levenson's Self-report Psychopathy Scale; (b) the Psychopathic Personality Inventory; and (c) the Triarchic Psychopathy Measure; and three measures of utilitarian moral judgment: (a) trolley dilemmas; (b) the Consequences, Norms, and Inaction (CNI) model of moral decision-making; and (c) the Oxford Utilitarianism Scale. When using the traditional approach to moral judgment (i.e., trolley dilemmas, instrumental harm, traditional score from the CNI model), we found that higher levels of psychopathic traits were associated with a higher utilitarian tendency. When using the modeling approach, we found that a higher level of psychopathic traits was related to weaker sensitivity to moral norms and less action averse in morally problematic situations. In addition, we found negative associations between impartial beneficence and all psychopathy scores.

Abstract
OBJECTIVE Anorexia nervosa (AN) is characterised by dysfunctional cognitive biases but these have rarely been investigated in adolescents with AN. The present study systematically assessed cognitive biases in adolescents with AN and addressed the questions of content-specificity (i.e., do biases occur only for eating disorder-related information?) and disorder-specificity (i.e., are biases unique to individuals with AN?). METHODS Cognitive biases on three information processing levels (attention, interpretation, memory) and for two types of information content (eating disorder-related, non-eating disorder-related) were assessed within a single experimental paradigm based on the Scrambled Sentences Task. 12-18-year-old adolescents with AN (n = 40) were compared to a healthy (HC; n = 40) and a clinical (girls with depression and/or anxiety disorders; CC; n = 34) control group. RESULTS Both clinical groups (AN and CC) showed pronounced negative interpretation and memory biases compared to the HC group, for both disorder-related and non-disorder-related information. Attention biases could not be analysed. CONCLUSION The results support the hypothesis that adolescents with AN show negative cognitive biases but these were not limited to disorder-related information. Adolescents with depression and/or anxiety disorders showed similar biases, suggesting them to be transdiagnostic phenomena. Important implications for cognitive-behavioural theories of AN, subsequent cognitive bias modification studies in AN, as well as clinical practice are discussed.

Abstract
PURPOSE OF REVIEW Major Depressive Disorder (MDD) is characterized by persistent symptoms such as fatigue, loss of interest in activities, feelings of sadness and worthlessness. MDD often coexist with cardiovascular disease (CVD), yet the precise link between these conditions remains unclear. This review explores factors underlying the development of MDD and CVD, including genetic, epigenetic, platelet activation, inflammation, hypothalamic-pituitary-adrenal (HPA) axis activation, endothelial cell (EC) dysfunction, and blood-brain barrier (BBB) disruption. RECENT FINDINGS Single nucleotide polymorphisms (SNPs) in the membrane-associated guanylate kinase WW and PDZ domain-containing protein 1 (MAGI-1) are associated with neuroticism and psychiatric disorders including MDD. SNPs in MAGI-1 are also linked to chronic inflammatory disorders such as spontaneous glomerulosclerosis, celiac disease, ulcerative colitis, and Crohn's disease. Increased MAGI-1 expression has been observed in colonic epithelial samples from Crohn's disease and ulcerative colitis patients. MAGI-1 also plays a role in regulating EC activation and atherogenesis in mice and is essential for Influenza A virus (IAV) infection, endoplasmic reticulum stress-induced EC apoptosis, and thrombin-induced EC permeability. Despite being understudied in human disease; evidence suggests that MAGI-1 may play a role in linking CVD and MDD. Therefore, further investigation of MAG-1 could be warranted to elucidate its potential involvement in these conditions.

Abstract
Most theories of suicide propose within-person changes in psychological states cause suicidal thoughts/behaviors; however, most studies use between-person analyses. Thus, there are little empirical data exploring current theories in the way they are hypothesized to occur. We used a form of statistical modeling called group iterative multiple model estimation (GIMME) to explore one theory of suicide: The Interpersonal Theory of Suicide (IPTS). GIMME estimates personalized statistical models for each individual and associations shared across individuals. Data were from a real-time monitoring study of individuals with a history of suicidal thoughts/behavior (adult sample: participants = 111, observations = 25,242; adolescent sample: participants = 145, observations = 26,182). Across both samples, none of theorized IPTS effects (i.e., contemporaneous effect from hopeless to suicidal thinking) were shared at the group level. There was significant heterogeneity in the personalized models, suggesting there are different pathways through which different people come to experience suicidal thoughts/behaviors. These findings highlight the complexity of suicide risk and the need for more personalized approaches to assessment and prediction.

Abstract
Objective Physical activity (PA) and sedentary behavior (SB) include several domains, whether the association of PA and SB with perceived stress is domain-specific is not clear. This study aims to identify associations of physical activity (exercise and housework) and leisure-time sedentary behavior (LTSB) with perceived stress among Chinese adults. Methods The data were collected from the 2015 China Health and Nutrition Survey (CHNS). Respondents completed multiple questionnaires developed by the CHNS team, from which we extracted and sorted PA and LTSB data. Perceived stress was measured using the 14-item Perceived Stress Scale. PA was measured using a questionnaire covering 7 types of commonly practiced exercises and 4 types of housework activities among Chinese individuals. Consecutive questions were used to inquire about the time spent on each type of PA. The measurement of LTSB was conducted in the same manner. Data analysis involved Chi-square test and logistic regression. Results 11,471 adults were included, with an average age of 52.3 years, and 48.3 % were male. 69.9 % (8,019) of respondents reported high perceived stress. Following adjustment for age, gender and other factors, perceived stress was lower for adults reporting medium exercise time (1-2 h) compared with excessively (≥2 h) (OR=1.314 [95 %CI 1.071, 1.612], P<0.001) and least (<1 h) (OR=1.273 [95 %CI 1.115, 1.413], P<0.001) active adults. Perceived stress was higher for adults reporting less housework time (<1 h) compared with adults spending medium (1-2 h) (OR=0.860 [0.744, 0.993], P<0.05) and long (≥2 h) (OR=0.725 [95 %CI 0.628, 0.838], P<0.001) time on housework. Low-level LTSB (<2 h) was associated with higher perceived stress than medium- (2-4 h) (OR=0.817 [0.718, 0.930], P<0.01) and high-level LTSB (≥4 h) (OR=0.668 [0.577, 0.773], P<0.001). Conclusions The association of PA and SB with perceived stress is domain-specific. Medium exercise time and extended housework time are associated with reduced perceived stress. Additionally, our findings suggesting that increasing the time spent on LTSB is linked to lower perceived stress levels.

Abstract
Prospective memory (PM) is the ability to remember an intention in the future. Individuals with depression are candidates for PM failures, resulting in detrimental consequences, such as forgetting to take a medication or implement therapeutic techniques; inaccurate assessments of one's PM abilities can exacerbate these issues. The current study examined if appraisals about one's prospective memory (meta-PM) performance differs between healthy and depressed adults. Data were gathered from 137 adults and included self-reported depression, PM beliefs, objective PM, and assessment of executive functions (EFs). Participants were separated into depressed/healthy categories based on a self-report measure. There was a non-significant correlation between self-reported PM and objective PM for both depressed (r = .06, p = .61) and healthy (r = .08, p = .52) groups, suggesting both groups had inaccurate meta-PM. There were non-significant differences in meta-PM between these groups (Fisher's Z = -0.09, p = .93), but exploratory gender analyses revealed women's meta-PM was significantly less accurate than men's. Women had higher reports of depression and PM complaints compared to men. This study lends evidence that depression is not necessarily related to worse meta-PM accuracy, despite depression's association with memory complaints, and that women are at greater risk for inaccurate meta-PM.

Abstract
AIM Non-suicidal self-injury (NSSI) is a highly prevalent phenomenon during adolescence. Nonetheless, research on predictors of the clinical course of NSSI over time is still scarce. The present study aimed at investigating the impact of adverse childhood experiences (ACE) and hypothalamus-pituitary-adrenal (HPA) axis functioning on the longitudinal course of NSSI. METHODS In a sample of n = 51 help-seeking adolescents engaging in NSSI, diurnal cortisol secretion (CAR, cortisol awakening response; DSL, diurnal slope), hair cortisol concentrations and ACE were assessed at baseline. Clinical outcome was defined by change in the frequency of NSSI in the past 6 months measured 12 and 24 months after the baseline assessments. Mixed-effects linear regression models were used to test for effects of ACE and HPA axis functioning on the course of NSSI. RESULTS ACE and HPA axis functioning did not show main but interaction effects in the prediction of NSSI frequency over time: Adolescents with a low severity of ACE and either an increased CAR or a flattened DSL showed a steep decline of NSSI frequency in the first year followed by a subsequent increase of NSSI frequency in the second year. CONCLUSIONS Our findings could be interpreted in the sense of high diurnal cortisol concentrations in the absence of ACE being favorable for clinical improvement on the short-term but bearing a risk of allostatic load and subsequent increase of NSSI frequency. In contrast, adolescents with severe ACE may benefit from elevated cortisol concentrations leading to slower but lasting decreases of NSSI frequency.

Abstract
OBJECTIVES The study compared the utility of two approaches for collecting real-world listening experiences to predict hearing-aid preference: a retrospective questionnaire (Speech, Spatial, and Qualities of Hearing Scale [SSQ]) and in-situ Ecological Momentary Assessment (EMA). The rationale being that each approach likely provides different and yet complementary information. In addition, it was examined how self-reported listening activity and hearing-aid data-logging can augment EMAs for individualized and contextualized hearing outcome assessments. DESIGN Experienced hearing-aid users (N = 40) with mild-to-moderate symmetrical sensorineural hearing loss completed the SSQ questionnaire and gave repeated EMAs for two wear periods of 2-weeks each with two different hearing-aid models that differed mainly in their noise reduction technology. The EMAs were linked to a self-reported listening activity and sound environment parameters (from hearing-aid data-logging) recorded at the time of EMA completion. Wear order was randomized by hearing-aid model. Linear mixed-effects models and Random Forest models with five-fold cross-validation were used to assess the statistical associations between listening experiences and end-of-trial preferences, and to evaluate how accurately EMAs predicted preference within individuals. RESULTS Only 6 of the 49 SSQ items significantly discriminated between responses made for the end-of-trial preferred versus nonpreferred hearing-aid model. For the EMAs, questions related to perception of the sound from the hearing aids were all significantly associated with preference, and these associations were strongest in EMAs completed in sound environments with predominantly low SNR and listening activities related to television, people talking, nonspecific listening, and music listening. Mean differences in listening experiences from SSQ and EMA correctly predicted preference in 71.8% and 72.5% of included participants, respectively. However, a prognostic classification of single EMAs into end-of-trial preference with a Random Forest model achieved a 93.8% accuracy when contextual information was included. CONCLUSIONS SSQ and EMA predicted preference equally well when considering mean differences, however, EMAs had a high prognostic classifications accuracy due to the repeated-measures nature, which make them ideal for individualized hearing outcome investigations, especially when responses are combined with contextual information about the sound environment.

Abstract
Due to its reliance on heterogeneous symptomatology, the accurate diagnosis of psychotic disorders remains a challenging task in clinical practice. Precise and early diagnosis of psychotic disorders facilitates early intervention, which has been shown to have substantial benefits for long-term outcomes. Still, the lack of specific biomarkers is an important limitation in early diagnosis and intervention. Exosomes, which act as messengers between cells, including brain cells, contain a vast array of molecules that hold promise for unveiling disorder-specific abnormalities. In this review, we discuss recent evidence highlighting the potential of circulating exosomes and brain-derived exosomes as valuable tools for the identification of accessible, non-invasive, and blood-based biomarkers of psychotic symptomatology and risk. We discuss current limitations in biomarker discovery studies focusing on exosomes. To enhance diagnosis specificity and treatment response, we also provide guidance for future investigations that need to target biomarkers of risk and relapse, as well as consider duration of untreated psychosis, biological sex, and other factors in the multifactorial biosignature of psychosis.

Abstract
Parental incarceration is an adverse childhood experience that inequitably burdens families of color and affects millions of U.S. children and adolescents. Although racialized disparities in exposure to parental incarceration are often acknowledged, researchers have yet to examine whether manifestations of racism may affect the link between parental incarceration and youth outcomes. This study provides a first look at how parental incarceration relates to health vulnerabilities in the Adolescent Brain Cognitive Development (ABCD) study, an ongoing, population-based study of U.S. children born between 2006 and 2008. We start by describing exposure to parental incarceration and then examine how parental incarceration, state-level racial prejudice, and discrimination relate to health risks among 9191 White (66%), Black (19%), or Hispanic (15%) youth. Consistent with what we know about pervasive racialized disparities in the U.S. criminal legal system, we find that 19.3% of Black children in our sample have experienced parental incarceration, followed by 7.8% of Hispanic children, and 4.8% of White children. Results of multilevel mixed models further indicate that parental incarceration was associated with increased health risks among White children whereas family economic hardship and discrimination experiences were more robustly associated with health vulnerabilities among Black and Hispanic children. Additional analyses explored whether parental incarceration was associated with other outcomes among Black and Hispanic children, revealing increased risk for behavior problems contingent upon parental incarceration and discrimination for Black children and Hispanic boys. Among Hispanic girls, parental incarceration was associated with increased risk of behavior problems in states with higher levels of racism. Results suggest that parental incarceration contributes to risk among early adolescents across racialized groups, but that the specific toll it takes depends on outcomes assessed and the context in which it occurs.

Abstract
Background Internet exclusion and depressive symptoms are prevalent phenomena among older adults; however, the association between internet exclusion and depressive symptoms remains limited. This study aims to investigate the association between internet exclusion and depressive symptoms among older adults from high-income countries (HICs) and low- and middle-income countries (LMICs). Methods We conducted a comprehensive longitudinal, cross-cultural analysis, and the participants were adults aged 60 years and older from 32 countries participating in five nationally representative longitudinal cohort studies: the Health and Retirement Study (HRS), the English Longitudinal Study of Ageing (ELSA), the Survey of Health, Ageing and Retirement in Europe (SHARE), the China Health and Retirement Longitudinal Study (CHARLS), and the Mexican Health and Ageing Study (MHAS). Internet exclusion was defined as the self-reported absence from internet use. Depressive symptoms were evaluated using the Centre for Epidemiologic Studies of Depression scale (CES-D) or the Euro-Depression scale (Euro-D). These five cohorts, being heterogeneous, were respectively conducted with panel data analysis. Logistic regression, implemented within the generalized estimating equations framework, was used to examine the association between internet exclusion and the likelihood of experiencing depressive symptoms, adjusting for the causal-directed-acyclic-graph (DAG) minimal sufficient adjustment set (MSAS), including gender, age, education, labour force status, household wealth level, marital status, co-residence with children, residence status, cognitive impairment, and functional ability. Findings Our study included a total of 129,847 older adults during the period from 2010 to 2020, with a median follow-up of 5 (2, 7) years. The pooled proportion of internet exclusion was 46.0% in HRS, 32.6% in ELSA, 54.8% in SHARE, 92.3% in CHARLS, and 65.3% in MHAS. Internet exclusion was significantly associated with depressive symptoms across all cohort studies: HRS (OR = 1.13, 95% CI 1.07-1.20), ELSA (OR = 1.22, 95% CI 1.11-1.34), SHARE (OR = 1.55, 95% CI 1.47-1.62), CHARLS (OR = 1.49, 95% CI 1.26-1.77), and MHAS (OR = 1.48, 95% CI 1.39-1.58). Moreover, internet exclusion was found to be associated with all dimensions of depression in the SHARE, MHAS, and ELSA cohorts (except for sleep and felt sad) cohorts. Interpretation A considerable proportion of older adults experienced internet exclusion, particularly those in LMICs. Internet exclusion among older adults, irrespective of their geographic location in HICs or LMICs, was associated with a higher likelihood of experiencing depressive symptoms, which demonstrated the importance of addressing barriers to internet access and promoting active participation in the internet society among older adults.

A pilot study of the role of the BDNF Val66Met polymorphism in response to exercise-augmented exposure therapy for posttraumatic stress disorder. Psychoneuroendocrinology 2024; 167:107106.

Abstract
Brain-Derived Neurotrophic Factor (BDNF) is implicated in extinction learning, which is a primary mechanism of exposure therapy for posttraumatic stress disorder (PTSD). Brief aerobic exercise has been shown to promote BDNF release and augment extinction learning. On the premise that the Val allele of the BDNF Val66Met polymorphism facilitates greater release of BDNF, this study examined the extent to which the Val allele of the BDNF polymorphism predicted treatment response in PTSD patients who underwent exposure therapy combined with aerobic exercise or passive stretching. PTSD patients (N = 85) provided saliva samples in order to extract genomic DNA to identify Val/Val and Met carriers of the BDNF Val66Met genotype, and were assessed for PTSD severity prior to and following a 9-week course of exposure therapy combined with aerobic exercise or stretching. The sample comprised 52 Val/Val carriers and 33 Met carriers. Patients with the BDNF high-expression Val allele display greater reduction of PTSD symptoms at posttreatment than Met carriers. Hierarchical regression analysis indicated that greater PTSD reduction was specifically observed in Val/Val carriers who received exposure therapy in combination with the aerobic exercise. This finding accords with animal and human evidence that the BDNF Val allele promotes greater extinction learning, and that these individuals may benefit more from exercise-augmented extinction. Although preliminary, this result represents a possible avenue for augmented exposure therapy in patients with the BDNF Val allele.

Abstract
OBJECTIVE To explore the association between insomnia symptoms and cognitive flexibility among undergraduates, along with its potential neural mechanisms. METHOD A total of 102 participants were divided into insomnia (n = 55) and control (n = 47) groups based on sleep status. Cognitive flexibility was assessed using the Cognitive Flexibility Inventory (CFI) and the Number-Letter Task (N-L task). EEG data were recorded during the N-L task. RESULTS The insomnia group exhibited lower CFI scores and higher switch costs in reaction time and accuracy compared to the control group. ERP analysis showed differences in P2, N2, and P3 component amplitudes between the two groups, with reduced N2 amplitude in the insomnia group under repeat trials. Time-frequency analysis revealed larger theta band event related synchronization in the frontal region and smaller theta band ERS in the parietal region under switch trials in the control group; the alpha band event-related desynchronization in the parietal region under repeat trials was significantly smaller in the control group compared to switch trials. CONCLUSION Compared to undergraduates with normal sleep, those with insomnia symptoms exhibited reduced cognitive flexibility, which may be associated with some alterations in brain electrophysiological activities.

Abstract
Our intricate social brain is implicated in a range of brain disorders, where social dysfunction emerges as a common neuropsychiatric feature cutting across diagnostic boundaries. Understanding the neurocircuitry underlying social dysfunction and exploring avenues for its restoration could present a transformative and transdiagnostic approach to overcoming therapeutic challenges in these disorders. The brain's default mode network (DMN) plays a crucial role in social functioning and is implicated in various neuropsychiatric conditions. By thoroughly examining the current understanding of DMN functionality, we propose that the DMN integrates diverse social processes, and disruptions in brain communication at regional and network levels due to disease hinder the seamless integration of these social functionalities. Consequently, this leads to an altered balance between self-referential and attentional processes, alongside a compromised ability to adapt to social contexts and anticipate future social interactions. Looking ahead, we explore how adopting an integrated neurocircuitry perspective on social dysfunction could pave the way for innovative therapeutic approaches to address brain disorders.

Abstract
Psychological stress is generally accepted to be associated with an increased risk of cardiovascular disease (CVD), but results have varied in terms of how stress is measured and the strength of the association. Additionally, the mechanisms and potential causal links have remained speculative despite decades of research. The physiological responses to stress are well characterized, but their contribution to the development and progression of CVD has received little attention in empirical studies. Evidence suggests that physiological responses to stress have a fundamental role in the risk of CVD and that haemodynamic, vascular and immune perturbations triggered by stress are especially implicated. Stress response physiology is regulated by the corticolimbic regions of the brain, which have outputs to the autonomic nervous system. Variation in these regulatory pathways might explain interindividual differences in vulnerability to stress. Dynamic perturbations in autonomic, immune and vascular functions are probably also implicated as CVD risk mechanisms of chronic, recurring and cumulative stressful exposures, but more data are needed from prospective studies and from assessments in real-life situations. Psychological assessment remains insufficiently recognized in clinical care and prevention. Although stress-reduction interventions might mitigate perceived stress levels and potentially reduce cardiovascular risk, more data from randomized trials are needed.

Abstract
We propose a psychologically-informed concept of social health to join physical and mental components in a more comprehensive assessment of human health. Although there is an extensive literature on the importance of social relationships to health, a theoretical framework is needed to coalesce this work into a codified conceptualisation of social health, defined here as adequate quantity and quality of relationships in a particular context to meet an individual's need for meaningful human connection. Informing this novel conceptualisation, we outline eight key propositions to guide future research and theory on social health, including five propositions focused on the conceptualisation of social health and three focused on its population patterning. The former five propositions include that social health is an outcome in its own right, that health interventions can have divergent effects on social versus physical and mental aspects of health, that social health has independent effects on quality of life, that it is a dynamic and contextual construct, and that it is embedded and encoded in the human body (and mind). The utility of the social health concept is further revealed in its significance for understanding and addressing population health concerns, such as health inequalities experienced by marginalised groups.

Abstract
INTRODUCTION Preventing nicotine use among youth is a public health priority. Nicotine use emerges from complex relationships between numerous factors. This project used network analysis to model behavioral precursors of nicotine use (knowledge, attitudes, perceptions, intentions) among youth who had never used nicotine and determine which predicted future trajectories of use across multiple nicotine products. METHODS Data were from the Population Assessment of Tobacco and Health study (2013-2018; analyzed 2023-2024), youth ages 12-17, who reported never using nicotine at Wave 1. Network structure was determined for behavioral precursors at Wave 1 and central network nodes were identified (N=5,087). Central nodes were then tested as predictors of trajectories of use across multiple nicotine products during Waves 1-4 (N=3,851). RESULTS Central nodes of the Wave 1 network were harm perception, expectancy that tobacco would calm anger/reduce stress, and intention to try. Those with lower intent to try at Wave 1 had lower odds of being in an Experimentation or Use class versus a Nonuse class during Waves 1-4 (p<0.0001). Those with more accurate harm perception had lower odds of being in an Experimentation versus Nonuse class (p=0.004). Those with positive expectancies had higher odds of being in an Experimentation versus Nonuse or Use class (p=0.04, 0.02). CONCLUSIONS Findings suggest a network model of behavioral precursors of nicotine use that can be tested, including central nodes that predicted trajectories of use across multiple nicotine products, and therefore may be priority intervention targets.

[PMID: 39094382 PMCID: PMC11338517 DOI: 10.1016/j.drugalcdep.2024.111396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 06/02/2024] [Accepted: 06/24/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Cannabis demand (i.e., relative value) is usually assessed as a trait-level risk-factor for cannabis use and consequences. This study examined within-person variability in day-level intensity (i.e., amount consumed at zero cost) and Omax (i.e., maximum cannabis expenditure) and tested hypotheses that demand would be positively associated with day-level cannabis use. METHODS Young adults (n=85) reporting past-month simultaneous alcohol and cannabis use completed two daily surveys for 30 days. Morning surveys assessed prior-day cannabis use and evening surveys assessed day-level demand (i.e., intensity, Omax). Multilevel models tested day-level effects of intensity and Omax on any cannabis use and flower use frequency and quantity (i.e., grams). RESULTS Approximately 52 % and 46 % of variability in intensity and Omax, respectively, was due to within-person change. At the day-level, higher intensity and Omax were associated with higher likelihood of any cannabis use, regardless of formulation; Omax was associated with use of flower in particular; and intensity was associated with the highest quantity of use. At the person-level, only Omax was associated with flower use likelihood, and only intensity was associated with flower quantity across days. CONCLUSIONS Cannabis demand demonstrated day-to-day variability, conceivably in response to various internal states and external factors. Intensity and Omax were related to elevated likelihood of using any cannabis, particularly flower, at the day-level. Overall, these data illustrate the validity and utility of brief cannabis demand measures, which might be used to further understand cannabis' reinforcing value at a fine-grained level.

Abstract
Objective This study investigated the reasons why pedohebephilic clients disclose their sexual attraction to children in therapy and the experiences associated with this decision among English-speaking samples. Method: The pre-registered online survey combined (1) quantitative correlational data of self-reported improvement, alliance, therapist reaction to disclosure, and the belief that mandatory reporting laws were in place, and (2) qualitative data about reasons for disclosure or no disclosure as well as perceived consequences. The sample consisted of pedohebephilic people who have been clients in therapy and have disclosed (n = 96) or not disclosed (n = 40). Results: While the disclosure and no disclosure groups did not differ in improvement or beliefs about mandatory reporting, those who had disclosed reported a stronger alliance. Clients who did not perceive the therapist's reaction as supportive reported less improvement than the no disclosure group. Thematic analysis of qualitative data identified three themes concerning motives for disclosing or not disclosing and a fourth regarding differential impacts of disclosure. Discussion: This study indicates that disclosing pedohebephilia does not in and of itself lead to improvement but is contingent on a therapist's reaction.

Abstract
BACKGROUND Internationally, over one-third of women experience birth trauma, leading to adverse mental health outcomes. Poor communication with healthcare professionals is a primary contributing factor. Paramedics attend various clinical presentations, including childbirth, yet their potential impact on women's birth experiences has been largely overlooked. METHODS A systematic literature search was conducted following the Joanna Briggs Institute methodological framework. The search identified 1015 potentially suitable articles, and 5 articles met the inclusion criteria. Data was analysed using reflexive thematic analysis from a feminist standpoint. RESULTS Three themes were generated: 1. First Impressions Count: paramedic demeanour impacted the woman's sense of safety and perception of paramedic clinical competence. 2. Choice as a Pathway to Control: when paramedics involved women in decision-making, it led to empowerment, while non-involvement led to women becoming passive participants. 3. Exposed, Violated and Disempowered: some paramedics disrespected and abused women, treating them solely as objects for the purpose of producing a baby. CONCLUSIONS This review highlights the influence of paramedic communication on women's birth experiences. While some paramedics communicated respectfully, other paramedics were the perpetrators of Obstetric Violence. Future research should inform paramedic education and improve outcomes for birthing women.

Abstract
Pyroptosis is an inflammatory programed cell death process that plays a crucial role in cancer therapeutic, while Gasdermin-D is a critical effector protein for pyroptosis execution. This review discusses the intricate interactions between Gasdermin-D and some non-coding RNAs (lncRNA, miRNA, siRNA) and their potential application in the regulation of pyroptosis as an anticancer therapy. Correspondingly, these ncRNAs significantly implicate in Gasdermin-D expression and function regarding the pyroptosis pathway. Functioning as competing endogenous RNAs (ceRNAs), these ncRNAs might regulate Gasdermin-D at the molecular level, underlying fatal cell death caused by cancer and tumor propagation. Therefore, these interactions appeal to therapeutics, offering new avenues for cancer treatment. It address this research gap by discussing the possible roles of ncRNAs as mediators of gasdermin-D regulation. It suggest therapeutic strategies based on the current research findings to ensure the interchange between the ideal pyroptosis and cancer cell death.

It's a balancing act: The ratio of maladaptive (vs. All) emotion regulation strategies is associated with depression. Behav Res Ther 2024; 180:104600.

Abstract
Research on emotion regulation (ER) has increasingly recognized that people use multiple strategies simultaneously, often referred to as ER repertoire. Prior research found that ER repertoire is associated with psychopathology, but results have been mixed. Indeed, research from recent years suggests that it is the quality of ERs, more than their quantity, that needs to be considered. Based on the combination of the literatures on ER repertoire, polyregulation, and ER flexibility, we propose a novel metric: the ratio of using putatively maladaptive (vs. all) ER strategies. Using this metric, we examine (1) maladaptive ER ratio changes during the transition to adolescence, a developmental period in which the prevalence of depression sharply increases, and (2) whether changes in maladaptive ER ratio are associated with depressive symptoms. One-hundred and thirty-nine youths (baseline age: 8-15) reported ER strategies and depression daily for 21 days. One year later, 115 completed another 28-day daily-diary (Nassessments = 5631). Our results show that almost all youth use at least some maladaptive ERs. Importantly, maladaptive ER ratio decreases over a year of adolescence for most youths. Conversely, an increased maladaptive ER ratio predicted depression increases on the daily and on the yearly level. These results shed light on typical and atypical development of ER flexibility and emphasize the need to consider the balance between ERs in relation to psychopathology.

Abstract
OBJECTIVES The network approach to psychopathology posits that mental disorders emerge from dynamic interactions among psychopathology-relevant variables. Ecological Momentary Assessment (EMA) is frequently used to assess these variables in daily life. Considering the transdiagnostic nature of the network approach to psychopathology, this study describes the development of a transdiagnostic EMA protocol for psychopathology. METHODS First, 96 clinicians completed an online survey, providing three EMA constructs for up to three disorders they specialize in, and three EMA constructs relevant across disorders (transdiagnostic constructs). Second, 12 focus groups were conducted with clinical experts for specific types of diagnoses (e.g., mood disorders, anxiety disorders). Finally, a selection of items was reached by consensus. Two raters independently coded the online survey responses with an inter-rater agreement of 87.3%. RESULTS Jaccard indices showed up to 52.6% overlap in EMA items across types of diagnoses. The most frequently reported transdiagnostic constructs were mood, sleep quality, and stress. A final set of EMA items is created based on items' frequency and informativeness, ensuring completeness across diagnoses and minimizing burden. CONCLUSIONS The described procedure resulted in a feasible EMA protocol to examine psychopathology transdiagnostically. Feasibility was helped by the overlap in mentioned symptoms across disorders. Such overlap raises questions about the validity of DSM categories.

Abstract
Mating represents a suite of fundamental adaptive problems for humans. Yet a community of men, called incels (involuntary celibates), forge their identity around their perceived inability to solve these problems. Many incels engage in misogynistic online hostility, and there are concerns about violence stemming from the community. Despite significant media speculation about the potential mating psychology of incels, this has yet to be formally investigated in the scientific literature. In the first formal investigation of incel mating psychology, we compared a sample (n = 151) of self-identified male incels with non-incel single males (n = 149). Findings revealed that incels have a lower sense of self-perceived mate-value and a greater external locus of control regarding their singlehood. Contrary to mainstream media narratives, incels also reported lower minimum standards for mate preferences than non-incels. Incels (and non-incel single men) significantly overestimated the importance of physical attractiveness and financial prospects to women, and underestimated the importance of intelligence, kindness, and humor. Furthermore, incels underestimated women's overall minimum mate preference standards. Our findings suggest that incels should be targeted for interventions to challenge cognitive distortions around female mate preferences. Implications for incels' mental health and misogynistic attitudes are discussed, as well as directions for future research.

Abstract
BACKGROUND AND AIMS Alcohol use and anxiety often co-occur, causing increased severity impairment. This protocol describes a randomized controlled trial (RCT) that aims to test the efficacy and cost-effectiveness of a web-based, self-guided alcohol and anxiety-focused program, compared with a web-based brief alcohol-focused program, for young adults who drink at hazardous levels and experience anxiety. It will also test moderators and mechanisms of change underlying the intervention effects. DESIGN This RCT will be conducted with a 1:1 parallel group. SETTING The study will be a web-based trial in Australia. PARTICIPANTS Individuals aged 17-30 years who drink alcohol at hazardous or greater levels and experience at least mild anxiety (n = 500) will be recruited through social media, media (TV, print) and community networks. INTERVENTION AND COMPARATOR Participants will be randomly allocated to receive a web-based, integrated alcohol-anxiety program plus technical and motivational telephone/e-mail support (intervention) or a web-based brief alcohol-feedback program (control). MEASUREMENTS Clinical measures will be assessed at baseline, post-intervention (2 months), 6 months (primary end-point), 12 months and 18 months. Co-primary outcomes are hazardous alcohol consumption and anxiety symptom severity. Secondary outcomes are binge-drinking frequency; alcohol-related consequences; depression symptoms; clinical diagnoses of alcohol use or anxiety disorder (at 6 months post-intervention), health-care service use, educational and employment outcomes; and quality of life. Mediators and moderators will also be assessed. Efficacy will be tested using mixed models for repeated measures within an intention-to-treat framework. The economic evaluation will analyze individual-level health and societal costs and outcomes of participants between each trial arm, while mediation models will test for mechanisms of change. COMMENTS This will be the first trial to test whether a developmentally targeted, web-based, integrated alcohol-anxiety intervention is effective in reducing hazardous alcohol use and anxiety severity among young adults. If successful, the integrated alcohol-anxiety program will provide an accessible intervention that can be widely disseminated to improve wellbeing of young adults, at minimal cost.

Abstract
This paper provides a summary of the role of nitric oxide (NO) and hormones in the development of chronic stress, anxiety, depression, and post-traumatic stress disorder (PTSD). These mental health conditions are prevalent globally and involve complex molecular interactions. Although there is a significant amount of research and therapeutic options available, the underlying mechanisms of these disorders are still not fully understood. The primary pathophysiologic processes involved in chronic stress, anxiety, depression, and PTSD include dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, the intracellular influence of neuronal nitric oxide synthase (nNOS) on transcription factors, an inflammatory response with the formation of nitrergic oxidative species, and reduced serotonergic transmission in the dorsal raphe nucleus. Despite the extensive literature on this topic, there is a great need for further research to clarify the complexities inherent in these pathways, with the primary aim of improving psychiatric care.

Abstract
Ambulatory assessment (AA) studies are frequently used to study emotions, cognitions, and behavior in daily life. But does the measurement itself produce reactivity, that is, are the constructs that are measured influenced by participation? We investigated individual differences in intraindividual change in momentary emotional clarity and momentary pleasant-unpleasant mood over the course of an AA study. Specifically, we experimentally manipulated sampling frequency and hypothesized that the intraindividual change over time would be stronger when sampling frequency was high (vs. low). Moreover, we assumed that individual differences in dispositional mood regulation would moderate the direction of intraindividual change in momentary pleasant-unpleasant mood over time. Students (n = 313) were prompted either three or nine times a day for 1 week (data collection took place in 2019 and 2020). Multilevel growth curve models showed that momentary emotional clarity increased within participants over the course of the AA phase, but this increase did not differ between the two sampling frequency groups. Pleasant-unpleasant mood did not show a systematic trend over the course of the study, and mood regulation did not predict individual differences in mood change over time. Again, results were not moderated by the sampling frequency group. We discuss limitations of our study (e.g., WEIRD sample) and potential practical implications regarding sampling frequency in AA studies. Future studies should further systematically investigate the circumstances under which measurement reactivity is more likely to occur.

Abstract
Background Colorectal cancer is major public health concern in China. This study seeks to explore the role of online cancer information seeking in influencing colorectal cancer screening, by taking into account one's coping appraisals (i.e., self-efficacy, response efficacy), threat appraisals (i.e., perceived severity, cancer worry) and cancer fatalism. Methods A cross-sectional survey was conducted with 730 participants in China recruited from a Chinese survey company's online panels. Path analysis was performed to investigate the relationships between the key constructs. Results First, online cancer information seeking increased both coping appraisals and threat appraisals. Second, threat appraisal did not significantly influence cancer fatalism, but coping appraisal reduced cancer fatalism. Third, cancer fatalism had no effects on colorectal cancer screening. Lastly, online cancer information also had a direct and positive relationship with cancer screening. Conclusions This research emphasises the need for health organisations to offer timely cancer information to people, and educate them about the importance of cancer screening. Health authorities may also regulate online cancer information to ensure that the information is accurate and appropriate in improving people's cancer prevention and cancer screening knowledge.

Abstract
The traits of the dark triad (narcissism, psychopathy, and Machiavellianism) capture the individual differences in the aversive personality. The dark triad has shown significant relations with behaviors that affect people's lives. One of the best-known instruments to assess the dark triad is the Dirty Dozen. However, controversy continues over the use of one general dark triad score or, conversely, three different scores. This study aimed to investigate the factor structure of the Dirty Dozen across eight global regions. There were 11,477 participants in 49 countries grouped into eight regions. Different factor structures were studied using confirmatory factor analyses. Both the three-dimensional models and the bifactor models (symmetrical or traditional and non-symmetrical or bifactor-[S - 1]) showed a good fit to the data. The bifactor-(S - 1) models (with psychopathy or Machiavellianism as the reference factors) show adequate fit to the data, supported by the coherence of the factorial loadings and the bifactor indices. Regarding measurement invariance for both models, configural, metric, and scalar invariance were satisfied. The results indicate that it is not clear whether a psychopathy or Machiavellianism reference factor predominates in the Dirty Dozen. For both models, templates are provided to obtain standardized scores for applied researchers in the eight studied world regions until future studies offer a greater amount of validity evidence for this instrument.

Abstract
We used item response theory (IRT) analysis to examine Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) item performance using data from three large samples of veterans (total N = 808) using both binary and ordinal rating methods. Relative to binary ratings, ordinal ratings provided good coverage from well below to well above average within each symptom cluster. However, coverage varied by cluster, and item difficulties were unevenly distributed within each cluster, with numerous instances of redundancy. For both binary and ordinal scores, flashbacks, dissociative amnesia, and self-destructive behavior items showed a pattern of high difficulty but relatively poor discrimination. Results indicate that CAPS-5 ordinal ratings provide good severity coverage and that most items accurately differentiated between participants by severity. Observed uneven distribution and redundancy in item difficulty suggest there is opportunity to create an abbreviated version of the CAPS-5 for determining PTSD symptom severity, but not DSM-5 PTSD diagnosis, without sacrificing precision.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) is an effective biological option for HIV prevention yet persistent disparities in PrEP uptake and retention exist among Hispanic/Latino men who have sex with men (MSM). We evaluated barriers and facilitators to PrEP care among Hispanic/Latino MSM at risk for and living with HIV. SETTING A small urban setting in the Northeastern United States. METHODS This was a mixed-methods, exploratory, sequential, qualitative and quantitative pilot study among Latino MSM at-risk and/or living with HIV across (1) semistructured qualitative interviews (N = 15) and (2) cross-sectional survey (N = 98). RESULTS Participants reported a diverse range of sexual identities, HIV statuses, and PrEP statuses. Qualitative participants described feelings of isolation in both Hispanic/Latino and queer communities that made it challenging to learn about HIV prevention or PrEP from peers. Participants in the survey indicated that they would be more inclined to uptake PrEP if PrEP were offered in primary care settings (n = 61; 62.2%); there were specific LGBTQ+ affirming medical settings (n = 36; 36.7%); and/or they could meet other people who are currently on PrEP and sharing experiences online (n = 46; 46.9%) or in person (n = 38; 38.8%). Findings were organized to reflect determinants and implementation strategies that could be used to improve PrEP uptake among this population. CONCLUSIONS This mixed-methods study identified several challenges and opportunities for increasing the reach of PrEP to Hispanic/Latino MSM. These findings should be used to inform tailored implementation strategies to promote PrEP uptake among this at-risk yet currently underserved population.

Abstract
BACKGROUND Post-marketing surveillance found montelukast use was associated with an increased risk of depression. However, results of observational studies are inconsistent. OBJECTIVE This study aimed to assess whether montelukast exposure is associated with depression and elucidate the possible molecular mechanism. METHOD We conducted a cross-sectional study of 9508 adults from the National Health and Nutrition Examination Survey (NHANES) 2007-2016. Multivariable regression was used to evaluate the association between montelukast exposure and depression. Network pharmacology was conducted to identify the mechanisms of montelukast on depression. RESULTS Montelukast exposure had a higher prevalence of depression (37.4 %). In a multivariable logistic regression model adjusted for sociodemographic, behavioural, and health characteristics, montelukast exposure was associated with depression (odds ratio [OR]: 1.61; confidence interval [CI]: 1.18-2.19). Network pharmacology was identified 69 key targets of montelukast on depression. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis suggested montelukast mainly works through multiple pathways in endocrine resistance, chemical carcinogenesis-receptor activation, estrogen signaling pathway, etc. LIMITATIONS: Cross-sectional data. CONCLUSIONS The study implies a potential positive association between long-term montelukast exposure and depression through multi-faceted mechanisms. It is suggested that attention be given to the possibility of depression in patients undergoing prolonged montelukast therapy.

Abstract
Previous research has shown that there are distinct types of children's shyness within eastern and western cultures, with different origins, developmental courses, and outcomes. However, the measures used to examine children's shyness in eastern contexts have been developed almost exclusively in the North American context. Whether shyness subtypes and their predictive associations are conserved between western and eastern cultures on a children's shyness measure developed in an eastern context is an empirical question. Here we examined (a) whether two subtypes from the Chinese Shyness Scale (i.e., anxious and regulated) were identified in a western context, and (b) whether cultural context moderated the relation between the two subtypes of shy behavior and a widely used western characterized social anxiety measure. The participants were children aged 3-5 years from China (Mage = 4.46 years, SD = 0.64, n = 182, 53.8% boys) and Canada (Mage = 3.99 years, SD = 0.82, n = 201, 42.3% boys). The results indicated that the two shyness subtypes and the one-factor social anxiety construct were identified in both cultures. Subsequently, latent moderation structural equation modelling revealed that anxious shyness was significantly and positively related to social anxiety in children from both countries, but more strongly in Canada. Conversely, regulated shyness was significantly and positively related to social anxiety in Canadian children, but not in Chinese children. Findings are discussed regarding possible cultural explanations for why the relations between two Chinese shyness subtypes and social anxiety are different in Chinese and Canadian contexts and their implications to understanding cross-cultural differences in developmental shyness. RESEARCH HIGHLIGHTS: Two subtypes of shyness (anxious and regulated shyness) reported in China were identified in both China and Canada Country/culture moderated the relation between shyness subtypes and social anxiety Anxious shyness was positively related to social anxiety in both countries Regulated shyness was positively related to social anxiety in Canadian children, but not in Chinese children.

Abstract
The error-related negativity (ERN) is an event-related potential that is observed after the commission of an error and is hypothesized to index threat sensitivity. The ERN is associated with multiple psychiatric disorders, but it is unclear if similar results are due to higher-order dimensions of psychopathology. When errors are punished, the ERN is further enhanced, which might better isolate threat sensitivity. However, few studies have examined whether psychopathology is associated with punishment enhancement of the ERN. In a clinical sample of 170 adults, the present study examined the association between pathological personality domains and predictable vs. unpredictable punishment-enhanced ERN. Results indicated that the ERN was enhanced when errors were punished compared to not punished. Greater negative emotionality was associated with a greater predictable punishment-enhanced ERN, while greater disinhibition was associated with smaller predictable punishment-enhanced ERN. The study suggests that higher-order pathological personality domains demonstrate discriminate relationships with punishment-enhanced error-related brain activity.

Abstract
IMPORTANCE The study highlights the potential and limitations of the Large Language Models (LLMs) in recognizing different states of motivation to provide appropriate information for behavior change. Following the Transtheoretical Model (TTM), we identified the major gap of LLMs in responding to certain states of motivation through validated scenario studies, suggesting future directions of LLMs research for health promotion. OBJECTIVES The LLMs-based generative conversational agents (GAs) have shown success in identifying user intents semantically. Little is known about its capabilities to identify motivation states and provide appropriate information to facilitate behavior change progression. MATERIALS AND METHODS We evaluated 3 GAs, ChatGPT, Google Bard, and Llama 2 in identifying motivation states following the TTM stages of change. GAs were evaluated using 25 validated scenarios with 5 health topics across 5 TTM stages. The relevance and completeness of the responses to cover the TTM processes to proceed to the next stage of change were assessed. RESULTS 3 GAs identified the motivation states in the preparation stage providing sufficient information to proceed to the action stage. The responses to the motivation states in the action and maintenance stages were good enough covering partial processes for individuals to initiate and maintain their changes in behavior. However, the GAs were not able to identify users' motivation states in the precontemplation and contemplation stages providing irrelevant information, covering about 20%-30% of the processes. DISCUSSION GAs are able to identify users' motivation states and provide relevant information when individuals have established goals and commitments to take and maintain an action. However, individuals who are hesitant or ambivalent about behavior change are unlikely to receive sufficient and relevant guidance to proceed to the next stage of change. CONCLUSION The current GAs effectively identify motivation states of individuals with established goals but may lack support for those ambivalent towards behavior change.

Abstract
PURPOSE A pervasive and deeply entrenched stigma of personality disorders exists. For other mental disorders, a large body of research suggests that continuum beliefs (i.e., the endorsement of continuum perspectives on mental health and psychopathology) stimulate more favorable attitudes toward affected persons. Additionally, mental disorder classification systems increasingly incorporate continuous personality disorder models. Yet, it is unclear how continuum beliefs are related to personality disorder stigma. This study evaluated the link of continuum beliefs with personality disorder stigma based on correlational and experimental data. METHODS A large general population sample (N = 848) completed self-report measures of continuum beliefs regarding personality disorders, desired social distance, and prejudice toward persons with personality disorders. Additionally, participants were randomly presented with information supporting a continuous or a dichotomous view of personality disorders. RESULTS Continuum beliefs were associated with lower desired social distance (r = - 0.19) and prejudice (r = - 0.22). Additionally, the brief continuum intervention was associated with increased continuum beliefs (d = 0.99) and decreased desired social distance (d = - 0.14) and prejudice (d = - 0.17). Finally, the intervention effects on desired social distance and prejudice were mediated by continuum beliefs. CONCLUSION This study suggests that highlighting continuum views on personality disorders in public communication and interventions might reduce personality disorder stigma.

Abstract
OBJECTIVE The Suicidal Ideation Questionnaire (SIQ) and the Suicidal Ideation Questionnaire-Junior (SIQ-Jr) were designed to capture suicidal ideation in adolescents and are often used in clinical trials. Our aim was to identify and appraise the published literature with respect to the validity, reliability, responsiveness, and interpretability of the SIQ and SIQ-Jr. METHOD We conducted a systematic review following COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines to identify, appraise, and synthesize published literature on measurement properties and interpretability of the SIQ and SIQ-Jr. We searched MEDLINE, Embase, APA PsycINFO, CINAHL, Web of Science, and Scopus from inception to May 16, 2023, to identify sources relevant to our aim. RESULTS We identified 15 sources meeting our eligibility criteria. The body of literature did not meet COSMIN standards to make recommendations for use with regard to these measurement instruments. CONCLUSION Further research is needed, with a focus on content validity and structural validity, prior to recommending the SIQ and SIQ-Jr for use in clinical practice and in clinical trials. No specific grant funding was used for this review. PLAIN LANGUAGE SUMMARY In this systematic review, authors analyzed 15 sources examining measurement properties of the Suicidal Ideation Questionnaire and Suicidal Ideation Questionnaire-Jr. Both measures are designed to capture suicidal ideation in adolescents and are used in clinical practice and clinical trials. The authors identified sufficient evidence for convergent validity for both measures. Authors concluded that further research is needed to support content validity, structural validity as a unidimensional scale (as they are often used) as well as their internal consistency, test-retest reliability, discriminative validity, predictive validity, and interpretability of these measures. The authors also emphasize the need to consider the limitations of these measures for researchers studying suicidal ideation and clinicians using these measures in their assessments of young people.

Abstract
Motivation in general, and social motivation in particular are important for interpersonal functioning in individuals with schizophrenia. Still, their roles after accounting for social cognition, are not well understood. The sample consisted of 147 patients with schizophrenia. General motivation was measured using the Behavioral inhibition/activation scale (BIS/BAS). Social motivation was measured by Passive social withdrawal and Active social avoidance items from PANSS. Interpersonal functioning was evaluated with Birchwood's Social Functioning Scale (SFS). We used Exploratory Graph Analysis for network estimation and community detection. Active social avoidance, passive social withdrawal, and social withdrawal/engagement (from SFS) were the most important nodes. In addition, three distinct communities were identified: Social cognition, Social motivation, and Interpersonal functioning. Notably, the BIS and BAS measures of general motivation were not part of any community. BAS showed stronger links to functioning than BIS. Passive social withdrawal was more strongly linked to interpersonal functioning than social cognitive abilities. Results suggest that social motivation, especially social approach, is more closely related to interpersonal functioning in schizophrenia than general motivation. In contrast, we found that general motivation was largely unrelated to social motivation. This pattern highlights the importance of type of motivation for understanding variability in interpersonal difficulties in schizophrenia.

Abstract
Neuropsychiatric symptoms (NPS) and mood disorders are common in individuals with mild cognitive impairment (MCI) and increase the risk of progression to dementia. Wearable devices collecting physiological and behavioral data can help in remote, passive, and continuous monitoring of moods and NPS, overcoming limitations and inconveniences of current assessment methods. In this longitudinal study, we examined the predictive ability of digital biomarkers based on sensor data from a wrist-worn wearable to determine the severity of NPS and mood disorders on a daily basis in older adults with predominant MCI. In addition to conventional physiological biomarkers, such as heart rate variability and skin conductance levels, we leveraged deep-learning features derived from physiological data using a self-supervised convolutional autoencoder. Models combining common digital biomarkers and deep features predicted depression severity scores with a correlation of r = 0.73 on average, total severity of mood disorder symptoms with r = 0.67, and mild behavioral impairment scores with r = 0.69 in the study population. Our findings demonstrated the potential of physiological biomarkers collected from wearables and deep learning methods to be used for the continuous and unobtrusive assessments of mental health symptoms in older adults, including those with MCI. TRIAL REGISTRATION: This trial was registered with ClinicalTrials.gov (NCT05059353) on September 28, 2021, titled "Effectiveness and Safety of a Digitally Based Multidomain Intervention for Mild Cognitive Impairment".

Can pre-visit exposure to virtual tours of healthcare facilities help reduce child and parent anxiety during outpatient surgical procedures? APPLIED ERGONOMICS 2024; 119:104308. [PMID: 38761553 DOI: 10.1016/j.apergo.2024.104308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/11/2024] [Accepted: 05/03/2024] [Indexed: 05/20/2024]
Abstract
AIM The study aims to evaluate the impact of exposure to a highly realistic virtual facility tour prior to the on-site visit on patients and their parent/care partner's self-reported anxiety and physiological measures on the day of the procedure. BACKGROUND Preoperative anxiety impacts pediatric surgical outcomes; therefore, it is important for healthcare providers to address and manage preoperative anxiety in pediatric patients to promote better outcomes and overall wellbeing. Providing patients with a preview of the care setting before the actual procedure can be highly beneficial in mitigating preoperative anxiety. METHODOLOGY In this pilot randomized experimental study, sixteen patient-care partner dyads scheduled to undergo a gastrointestinal procedure either received a virtual tour identical to the places experienced on the day of the procedure (experimental group) or received no virtual tour (control group). Self-reported measures of anxiety were collected from participants before and on the day of the procedure. Physiological measures of heart rate variability and skin conductance were collected on the day of the procedure from both groups. RESULTS There were no significant differences between the self-reported and physiological measures of anxiety between the child groups. However, parents in the control group reported lower levels of anxiety and demonstrated lower levels of stress based on their physiological measures. CONCLUSION Exposure to virtual facility tours days before the surgery was not helpful in positively impacting the psychological measures related to preoperative anxiety levels for the participants.

Abstract
BACKGROUND Devaluation of alcohol leads to reductions in alcohol choice and consumption; however, the cognitive mechanisms that underpin this relationship are not well-understood. In this study we applied a computational model of value-based decision-making (VBDM) to decisions made about alcohol and alcohol-unrelated cues following experimental manipulation of alcohol value. METHOD Using a pre-registered within-subject design, thirty-six regular alcohol consumers (≥14 UK units per week) completed a two-alternative forced choice task where they chose between two alcohol images (in one block) or two soft drink images (in a different block) after watching videos that emphasised the positive (alcohol value), and separately, the negative (alcohol devalue) consequences of alcohol. On each block, participants pressed a key to select the image depicting the drink they would rather consume. A drift-diffusion model (DDM) was fitted to reaction time and choice data to estimate evidence accumulation (EA) processes and response thresholds during the different blocks in each experimental condition. FINDINGS In the alcohol devalue condition, soft drink EA rates were significantly higher compared to alcohol EA rates (p = 0.04, d = 0.31), and compared to soft drink EA rates in the alcohol value condition (p = 0.01, d = 0.38). However, EA rates for alcoholic drinks and response thresholds (for either drink type) were unaffected by the experimental manipulation. CONCLUSIONS In line with behavioural economic models of addiction that emphasise the important role of alternative reinforcement, experimentally manipulating alcohol value is associated with changes in the internal cognitive processes that precede soft drink choice.

Abstract
The current study sought to provide evidence for a measure of schizoid personality disorder (SZD PD) traits using the Five-Factor Model framework of personality. In the first study, undergraduate participants (n = 496) completed the Five-Factor Schizoid Inventory (FFZI) and other self-report measures. The first half of the sample was used to develop the FFZI, while the second half was used to validate it. The FFZI demonstrated excellent internal consistency, convergent validity with measures of SZD PD and hypothesized IPIP-NEO facets, and discriminant validity with other PDs and non-hypothesized IPIP-NEO facets. The second study recruited MTurk participants (n = 181) and demonstrated preliminary support for the reliability and validity of the FFZI in an online, community sample. Ultimately, these data suggest that the FFZI is a useful measure of SZD PD and provide further evidence that SZD PD can be conceptualized as a maladaptive extension of introversion traits.

Abstract
Ecological momentary assessment (EMA) can be used to examine the dynamics of suicidal ideation in daily life. While the general acceptability and feasibility of EMA in suicide research has been established, further examination of potential iatrogenic effects (i.e., negative reactivity) and identifying those more likely to react negatively is needed. Participants (N = 82) with current suicidal ideation completed 21 days of EMA (4×/day) and filled in M = 78% (Med = 84%) of the EMA. No positive or negative affect reactivity was observed in EMA ratings over the study period. Retrospectively, most participants rated their experience as positive (69%); 22% indicated mood worsening, and 18% suicidal ideation reactivity. Those with more borderline personality traits, posttraumatic stress disorder (PTSD), and higher depressive, anxiety, and suicidal ideation symptoms, were more likely to report iatrogenic effects. In conclusion, while high compliance rates and lack of affect reactivity during EMA indicate that EMA is well tolerated in suicide research, a minority of participants may report subjective mood effects in retrospect.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155829. [PMID: 38941813 DOI: 10.1016/j.phymed.2024.155829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 05/03/2024] [Accepted: 06/13/2024] [Indexed: 06/30/2024]
Abstract
BACKGROUND Since the pathogenesis of depression is complex, antidepressant therapy remains unsatisfactory. Recent evidence suggests a link between depression and lipid metabolism. Saikosaponin (SS) exhibits antidepression and lipid-regulating effects in modern pharmacology. However, it is unknown whether lipid regulation is the key mechanism of the SS antidepressant effect and how it works. PURPOSE In this study, we investigated the relationship between the antidepressant activity of SS and the regulation of lipid metabolism and explored potential mechanisms. METHODS APOE-/- mice, in combination with the chronic unpredictable mild stress (CUMS) model, were used to study the relationship between SS antidepressant activity and lipid metabolism through behavioral, electrophysiological techniques, and non-targeted lipidomics. Western blot, primary cell culture technology, and laser speckle cerebral blood flow imaging were employed to elucidate potential mechanisms. GraphPad Prism was used for statistical analysis, and p < 0.05 was considered statistically significant. RESULTS APOE-/- mice exhibit more severe depressive-like behavior and dysregulation of sphingolipid metabolism in CUMS. SS alleviates depressive behavior and cortical sphingolipid metabolism disorder caused by CUMS, but has no effect on APOE-/- mice. SS alleviates the imbalance between ceramide (Cer) and sphingomyelin (SM) through acidic sphingomyelinase (AMSase). In addition, SS regulates neuronal glutamate release via sphingolipid metabolism, thereby alleviating the CUMS-induced inhibition of neurovascular coupling (regulates metabotropic glutamate receptor and IP3 receptor), which ameliorates the reduction of cerebral blood flow in depressed mice. CONCLUSION Our study highlights the role of lipid metabolism in the antidepressant activity of SS and explores its underlying mechanisms. This study provided new insights into the better understanding of the antidepressant mechanisms of phytomedicine while increasing the possibility of lipid metabolism as a therapeutic strategy for depression.

Abstract
Imbalances in dopamine activity significantly contribute to the pathophysiology of several neuropsychiatric disorders, including addiction, ADHD, schizophrenia, impulse control disorders, and Parkinson's Disease. Neuro(active)steroids, comprising endogenous steroids that finely modulate neuronal activity, are considered crucial regulators of brain function and behavior, with implications in various physiological processes and pathological conditions. Specifically, subclasses of Neuro(active)steroids belonging to the 5α reductase pathway are prominently involved in brain disorders characterized by dopaminergic signaling imbalances. This review highlights the neuromodulatory effects of Neuro(active)steroids on the dopamine system and related aberrant behavioral phenotypes. We critically appraise the role of pregnenolone, progesterone, and allopregnanolone on dopamine signaling. Additionally, we discuss the impact of pharmacological interventions targeting 5α reductase activity in neuropsychiatric conditions characterized by excessive activation of the dopaminergic system, ranging from psychotic (endo)phenotypes and motor complications to decision-making problems and addiction.

Abstract
RATIONALE Theories of addiction guide scientific progress, funding priorities, and policy development and ultimately shape how people experiencing or recovering from addiction are perceived and treated. Choice theories of addiction are heterogenous, and different models have divergent implications. This breeds confusion among laypeople, scientists, practitioners, and policymakers and reduces the utility of robust findings that have the potential to reduce the global burden of addiction-associated harms. OBJECTIVE Here we differentiate classes of choice models and articulate a novel framing for a class of addiction models, called contextual models, which share as a first principle the influence of the environment and other contextual factors on behavior within discrete choice contexts. RESULTS These models do not assume that all choice behaviors are voluntary, but instead that both proximal and distal characteristics of the choice environment-and particularly the benefits and costs of both drug use and non-drug alternatives-can influence behavior in ways that are outside of the awareness of the individual. From this perspective, addiction is neither the individual's moral failing nor an internal uncontrollable urge but rather is the result of environmental contingencies that reinforce the behavior. CONCLUSIONS Contextual models have implications for guiding research, practice, and policy, including identification of novel target mechanisms while also improving existing interventions.
