Long-term psychological impact of the pandemic COVID-19: Identification of high-risk groups and assessment of precautionary measures five months after the first wave of restrictions was lifted.

Critical facets of our lives have been disrupted by the COVID-19 outbreak for almost three years. During this time, there has been a lot of clinical and research interest in issues related to mental health. However, few have examined the pandemic's long-term psychological effects. The aims of the present study were to assess the long-term psychological impact of the pandemic COVID -19, five months after the first wave restriction measures were lifted, to identify high-risk groups and to address the use of precautionary measures (PM). Information about sociodemographic characteristics, mental health, coping mechanisms, and compliance with precautionary measures (PM) were all gathered in Cyprus through an anonymous online survey. The poll was completed by 1128 people (73% of whom were female). For the purposes of the present study, descriptive statistics and structural equation modeling were used. 32.3% of participants experienced moderate-to-severe anxiety symptoms, where 16.4% and 23% reported moderate-to-severe depression and post-traumatic stress symptoms respectively. Lower levels of anxiety, depression, and post-traumatic stress symptoms as well as greater compliance to PM were linked to higher levels of resilience. Additionally, subgroups of participants, at a higher risk for negative psychological effects were identified, such as women and young adults. Our findings demonstrate the long-lasting effects of the COVID-19 pandemic on mental health and provide guidance on how to deal with similar situations. It also raises questions about the concurrent effects on people with the long COVID syndrome.

Music and speech time perception of musically trained individuals: The effects of audio type, duration of musical training, and rhythm perception.

The perception of time is a subjective experience influenced by various factors such as individual psychology, external stimuli, and personal experiences, and it is often assessed with the use of the reproduction task that involves individuals estimating and reproducing the duration of specific time intervals. In the current study, we examined the ability of 97 musically trained participants to reproduce the durations of temporal intervals that were filled with music or speech stimuli. The results revealed a consistent pattern of durations being underestimated, and an association was observed between the duration of musical training and the level of accuracy in reproducing both music and speech tracks. In addition, speech tracks were overall reproduced more accurately, and as longer, than music tracks. Structural models suggested the presence of two, highly correlated, dimensions of time perception for speech and music stimuli that were related to the duration of musical training, but not with self-reported rhythm perception. The possible effects of arousal and pleasantness of stimuli on time perception are discussed within the framework of an internal clock model.

A Network Analysis Approach on the Psychological Flexibility/Inflexibility Model.

Acceptance and Commitment Therapy (ACT) is purported to work via targeting six interrelated processes summarized as the Psychological Inflexibility/Psychological Flexibility (PI/PF) model. However, the theoretical structure and interconnections of this model have not been sufficiently explored. Lacking are examinations of the interrelations among its components. Network Analysis (NA) can model PI/PF as a system of interconnected variables. We aimed at exploring the role and associations of the PI/PF model's components using NA in two different samples and sets of scales, and compare its structure across sub-samples. Sample 1 consisted of 501 individuals, who completed an online battery of questionnaires including the Multidimensional Psychological Flexibility Inventory, and Sample 2 consisted of 428 people, who completed an online set of six ACT measures, each assessing a component of the PI/PF model. NA could not verify the six ACT dimensions as distinct components. Values and Committed Action components were found to be strongly associated and combined in a group in both sets of measures and samples. Interestingly, Acceptance and Defusion were not the most central components as purported in some ACT conceptualizations, whereas Self-as-Context had a key role on both sets of measures and its items were often merged with Present Moment Awareness items. No significant differences were found in the comparison of networks across different subsamples and sets of scales. After combining different sets of scales, the six ACT components could not be completely verified as distinct entities, which might reflect problems with the theoretical model, or with the scales used. All components had critical roles in the model, particularly Self-as-Context, which reflects the need to redirect research towards this understudied construct. Findings point towards considerations of a triflex instead of a hexaflex ACT model.

Functional versus dysfunctional coping with physical pain: An experimental comparison of acceptance vs. avoidance coping.

This study compared acceptance vs. avoidance coping with acute physical pain, in a pain-induction experiment and examined both between and within-group differences, multi-methodically and multi-dimensionally using behavioral, physiological and self-report measures. The sample consisted of 88 University students (76.1% females; Mage = 21.33 years). Participants were randomly assigned to four instructed groups and participated twice in the Cold Pressor Task: (a) Acceptance followed by avoidance; (b) Avoidance followed by acceptance; (c) No instructions (control) followed by acceptance, and (d) No instructions (control) followed by avoidance. All analyses were conducted using repeated-measures ANOVAs. Randomized techniques analyses showed that participants receiving no instructions followed by acceptance reported significantly greater changes in physiological and behavioral measures across time. Low adherence to acceptance instructions was found, especially during the first phase. Exploratory analyses on actual techniques used (as opposed to taught technique) showed that participants using avoidance followed by acceptance exhibited significantly greater changes in physiological and behavioral measures across time. No significant differences were found for the self-report of negative affect outcome. Overall, our findings provide support to ACT theory, as participants might have to use firstly ineffective coping to understand what works best to cope with pain. This is the first study examining acceptance vs. avoidance coping both between and within individuals in physical pain, multi-methodically and multi-dimensionally.

Radiofrequency ablation for the treatment of a presumed enchondroma in the flat bones of the pelvis.

Herein, a 30-year-old Caucasian female who presented with a persistent pain in the right pelvic region due to an enchondroma and treated with RF ablation is described. An initial MRI of the pelvis revealed a well-circumscribed lesion in the right inferior ischiopubic ramus with a maximum diameter of 9.5 mm. The final diagnosis was established by a percutaneous CT-guided bone biopsy, which excluded malignancy and revealed an enchondroma. About a month after the biopsy, a percutaneous radiofrequency ablation (RFA) of the lesion was performed. The symptoms resolved completely gradually 2 months after the treatment and a follow-up imaging with MRI showed complete resolution of the pathological enhancement indicating necrosis of the lesion. RFA has not been previously reported as a treatment option of enchondromas found in flat bones of the pelvis and could be a safe alternative minimally invasive treatment option in such cases, avoiding major operations.

Assessment of indoor and outdoor air quality in primary schools of Cyprus during the COVID-19 pandemic measures in May-July 2021.

Combined pollutant effects from indoor and outdoor sources on children's health, while being at school have not been holistically tackled. The aim of the School Temperature and Environmental Pollutants Study (STEPS) was to perform a school population representative assessment of indoor air quality (IAQ) in primary schools of densely and intermediate populated areas of Cyprus (n = 42). The study took place during May-July 2021 when a school-specific COVID-19 protocol was in place. Questionnaire-based characteristics of schools/classrooms were collected along with 24/48-h long IAQ monitoring of air temperature, relative humidity (RH), particulate matter (PM), carbon dioxide (CO2) and volatile organic compounds (VOCs), using low-cost sensors. Mixed effect models assessed the IAQ determinants during school hours. Indoor PM, temperature, RH and VOCs increased with progressing school periods in the day, while indoor CO2 decreased. Indoor RH and CO2 were negatively associated with % open windows, while indoor PM2.5 was positively associated. Most of school time (85%), indoor air temperature exceeded the recommended upper limit (27 °C), while a third of indoor PM2.5 (24-h) measurements exceeded 15 µg/m3. The interplay of clean indoor air with adequate ventilation and adaptation to heat stress in schools is important and its comprehensive characterization requires holistic methodological approaches and tools.

Response tendencies due to item wording using eye-tracking methodology accounting for individual differences and item characteristics.

The discrepancy of the scores on responses to negatively and positively worded items has led to hypotheses of inattention, confusion, difficulty, and differential processing of negatively worded items. The present study, utilizing eye-tracking methodology, aimed to fill an explanatory gap regarding response behavior, providing observations on the item-level response process. It experimentally examined characteristics of the items (wording type, self-relevance) and characteristics of the respondents (neuroticism, verbal abilities, and mood) for their impact on response outcomes. A sample of 87 university students completed a computerized version of a questionnaire with items presented in four alternative wording types: positive, negative, negated positive, and negated negative; half of the items referred to attitudes toward the self and the other half to attitudes toward others. Participants' eye movements during item completion were recorded with the Gazepoint-GP3-HD desk-mounted eye tracker. In linear mixed effects models, wording type and self-relevance were found to relate to response time, time of viewing and revisits to the body of the items and the response options, indicating that there were effects at the stages of comprehension and selection of response. Neuroticism was associated with differential item responses, suggesting a role in later levels of the response process, the retrieval, judgment, and response selection stages. Eye-tracking measures can enhance the examination of response tendencies with regards to item content, item wording, and person characteristics.

Association of clinical characteristics, disease activity and health-related quality of life in SLE patients with major depressive disorder.

OBJECTIVE: To determine the contributing factors associated with major depressive disorder (MDD) in SLE patients and examine the association between disease-specific health-related quality of life [lupus quality of life (LupusQoL)] domains and MDD. METHODS: Depression was assessed by the patient health questionnaire (PHQ)-9, and scores ≥10 indicate MDD. Demographic data, LupusQoL domains, clinical and other features of the SLE patients were described and compared between MDD (PHQ-9 ≥10) and non-MDD (PHQ-9 <10) groups using χ2 tests for categorical variables and Wilcoxon rank sum tests for non-normal continuous variables. The risk of MDD was evaluated for the patient and physician-reported features individually using log-binomial models to estimate relative risks and 95% confidence limits. RESULTS: Eighty-eight patients with SLE met eligibility criteria, with a mean (range) age of 48.6 (19-80), mostly female (80%) and with a mean disease duration of 13.2 years. Compared with the non-MDD group, patients with MDD (n = 32, 36%) were more likely to have the following SLE manifestations: mucocutaneous, vascular, ocular, pulmonary and musculoskeletal involvement. Self-rated health described as poor/fair was markedly associated with MDD (P < 0.001, relative risk = 0.48). Based on relative risks, higher pain visual analogue score, and patient and physician global assessment scores were also linked to MDD. The LupusQoL domain scores were notably lower in the MDD patients, with a statistically significant reduction in all LupusQoL domains. CONCLUSION: Predictors of MDD in SLE patients include higher scores in pain and global assessment, poor or fair self-reported health, and specific organ involvement. These findings may help clinicians to recognize and manage MDD promptly.

Factorial Structure and Nomological Network of the Inventory of Callous-Unemotional Traits Accounting for Item Keying Variance.

The factorial structure of the Inventory of Callous Unemotional Traits (ICU) is currently under dispute. The present study aims to test the factorial structure of a Greek adaptation of the ICU by considering item keying variance and examining alternative theoretical and empirically derived models. Additionally, it aims to investigate the nomological network of the ICU subscales, after controlling for item keying variance. The sample consisted of 1536 Greek-Cypriot adolescents, who completed a battery of questionnaires, including the ICU. Results showed that the consideration of item keying variance improved the overall fit of all the examined models and led to significant changes in the predictive validity of the subscales, while method factors presented distinct patterns of associations with external variables. Overall, results suggest that ICU is contaminated by item keying variance, which can be filtered out to provide clinically useful insight into the factorial structure of the ICU.

Measurement of everyday dysexecutive symptoms in normal aging with the Greek version of the dysexecutive questionnaire-revised.

The Dysexecutive Questionnaire is a sensitive and ecologically valid measure of everyday dysexecutive symptoms. Recently, a revised version of the tool has been proposed (DEX-R). The current study aimed to examine the factorial validity of the Greek DEX-R, the level of agreement between the self and informant rating versions and the effect of age on each dysexecutive symptoms component. The questionnaire was administered to a sample of older adults (n = 235) and to a sample of informants (n = 187) in the context of the Neurocognitive Study for the Aging in Cyprus. Confirmatory Factor Analysis results showed that dysexecutive symptoms can be grouped into three underlying components or factors: (a) Motivation and Attention, (b) Flexibility, Fluency and Working Memory, and (c) Social Self-Regulation. Overall, the elderly reported more symptoms than their relatives, however the difference was significant only for the Flexibility, Fluency and Working memory factor. In a structural equation model, a weak positive effect of age was observed on the Flexibility, Fluency and Working Memory factor, based on the informant ratings. This study provides empirical evidence about the use of the DEX-R questionnaire in the Greek-speaking elderly population as a valid and reliable measure of everyday dysexecutive symptoms.

Geometric fluid approximation for general continuous-time Markov chains.

Fluid approximations have seen great success in approximating the macro-scale behaviour of Markov systems with a large number of discrete states. However, these methods rely on the continuous-time Markov chain (CTMC) having a particular population structure which suggests a natural continuous state-space endowed with a dynamics for the approximating process. We construct here a general method based on spectral analysis of the transition matrix of the CTMC, without the need for a population structure. Specifically, we use the popular manifold learning method of diffusion maps to analyse the transition matrix as the operator of a hidden continuous process. An embedding of states in a continuous space is recovered, and the space is endowed with a drift vector field inferred via Gaussian process regression. In this manner, we construct an ordinary differential equation whose solution approximates the evolution of the CTMC mean, mapped onto the continuous space (known as the fluid limit).

Psychological Inflexibility in Pain Scale: Greek adaptation, psychometric properties, and invariance testing across three pain samples.

The success of acceptance and commitment therapy (ACT) in improving life functioning among chronic pain patients is followed by an interest in investigating mechanisms of action via which it unfolds and validating measures to assess its key constructs. The Psychological Inflexibility in Pain Scale (PIPS-II) assesses pain avoidance and fusion. This is the first study to examine the measurement models of this instrument's Greek adaptation (G-PIPS-II) in patients with different pain localizations (i.e., chronic and headache). A community heterogeneous sample of chronic pain sufferers (N = 156) and two clinical samples comprising treatment-seeking chronic pain patients (N = 149) and treatment-seeking headache patients (N = 89) were recruited from nongovernmental chronic pain support organizations and primary care centers. Exploratory and confirmatory factor analyses demonstrated an acceptable model fit of the G-PIPS-II yielding a two-factor model: avoidance (8 items) and cognitive fusion (4 items). Moderate to high correlations with theoretically related measures supported its construct validity; reliability was high for the total scale and the Avoidance subscale and medium for the Cognitive Fusion subscale. Weak measurement invariance was established across the three pain groups, suggesting that regardless of pain localization, chronic pain and headache patients understand the two latent factors in a similar way. G-PIPS-II is a psychometrically sound instrument assessing two constructs targeted for change within ACT and is deemed a conceptually meaningful scale with items having similar meanings for patients with different pain localization.

The effects of ethnic group membership on bullying at school: when do observers dehumanize bullies?

The purpose of this experiment was to test how ethnic group membership of both the bullies and the victims influence the way that observers attribute human characteristics to bullies. Ethnic group membership was manipulated in terms of bullies' and victims' ethnicity (ingroup-majority group versus outgroup-minority group). Furthermore, we examined the mediating role of empathic concern towards the victim and perspective taking of the bully in the relation between ethnic group membership of bullies and victims and attributions of humanness to the bullies. We hypothesized that observers would attribute lower human characteristics to outgroup bullies when bullies inflict harm on an ingroup victim. Moreover, we expected that perspective taking of the bully and empathic concern towards the victim would mediate this relation. Analysis of data from a sample of 293 Greek-Cypriot adolescents fully corroborated our hypotheses. The findings are discussed in terms of the discrimination-based nature of bullying at school.

Smoking Consequences Questionnaire: Factor Structure and Invariance among Smokers and Non-Smokers.

BACKGROUND: The Smoking Consequences Questionnaire was developed to assess smoking expectancies, which have been found to be linked to the initiation and maintenance of smoking. OBJECTIVES: The purpose of the current study was to examine the factor structure of a modified brief version of the instrument in Greek and to test its invariance between groups of smokers and nonsmokers. METHODS: Participants were 813 Greek-Cypriot university students (524 females; Mean age =20.94, SD = 2.70) who completed this brief version of the instrument translated into Greek using the forward-backward method. RESULTS: Confirmatory factor analysis supported a four-factor structure: Negative Consequences, Positive Reinforcement, Negative Reinforcement and Appetite/Weight Control. Multigroup confirmatory factor analysis indicated configural, metric and partial scalar invariance of the instrument in groups of smokers and nonsmokers. Comparison of the mean difference in the invariant factors showed significant difference in appetite/weight control mean scores, whereas mean difference in negative consequences was not significant. Conclusions/Importance. Findings support the four-factor structure of the brief Greek version of the SCQ in a sample of young adults, and factorial invariance between smokers and nonsmokers. More expectancies about appetite/weight control among smokers compared to nonsmokers suggest focusing on this category of smoking expectancies in smoking prevention and cessation programs.

The role of metabolic syndrome factors on cognition using latent variable modeling: The neurocognitive study on aging.

OBJECTIVE: Although metabolic syndrome (MetS) has been shown to increase the risk of cognitive decline, it still remains unclear whether the risk is related to MetS as a whole or its individual factors. The aim of the present study was to explore whether MetS or its individual factors are associated with a lower cognitive function in older adults in a Mediterranean population using latent variable modeling. METHOD: Neurocognitive data from 640 Greek-Cypriot community dwellers (female 59.1%), aged ≥55 years, in good general health, were analyzed. Assessments of anthropometric, blood pressure, fasting blood glucose, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, and triglyceride concentrations were carried out to investigate the relationship between MetS factors and cognitive-linguistic outcomes of language, executive function, and verbal episodic memory. RESULTS: When the MetS factors were modeled as a single latent variable, they had small negative effects on language and executive functions. Significance was not retained after age and education were controlled for. When individual MetS factors along with age and education were modeled as predictors, there were moderate negative age effects, whereas education yielded strong positive effects on all three cognitive outcomes. Weak significant negative coefficients of body mass index (BMI) and blood glucose were found for executive functions, and a weak significant positive effect of BMI was found for memory. Separate analysis by sex resulted in minor but significant differences. CONCLUSION: BMI and blood glucose predicted cognitive performance after controlling for age and education, and thus their proper management should be taken into account for maintaining cognitive health in aging. Findings also demonstrate the importance of education and age in studies investigating cardiometabolic risk factors and cognitive function, as well as the need for further research on the effects of sex.

Osteoid osteoma of the scaphoid bone associated with flexor carpi radialis calcific tendinitis and treated with CT-guided RF ablation.

Osteoid osteomas of the wrist are relatively rare and the diagnosis is challenging due to atypical clinical features. We describe a case of an osteoid osteoma of the scaphoid bone associated with calcific tendinitis of the adjacent flexor carpi radialis tendon and periarticular soft tissue calcifications in a 21-year-old man presenting with radial-sided wrist pain. The lesion was successfully treated with CT-guided RF ablation. To our knowledge, this is the first description of an osteoid osteoma of the wrist associated with calcific tendinitis and periarthritis. In addition, we discuss the technical details and difficulties of CT-guided RF ablation of scaphoid osteoid osteomas.

Construct validity of the G-CPAQ and its mediating role in pain interference and adjustment.

The Chronic Pain Acceptance Questionnaire (CPAQ) is a measure of pain acceptance comprised of pain willingness (PW) and activity engagement (AE; McCracken et al., 2004). Concerns about the factorial structure of the CPAQ exist, as it is not yet clear whether PW and AE constitute 2 independent constructs or 1, pain acceptance. Concerns also exist about the internal and predictive validity of test score interpretations of this measure. This study also presents that the choice of predictor variables has contributed to theoretical confusion regarding the impact of pain acceptance on pain-related adjustment. The purpose of this study was: (a) to examine the psychometric properties of both the long (20 items) and short (8 items) versions of the Greek-Chronic Pain Acceptance Questionnaire (G-CPAQ); (b) to examine the utility of a 2-factor solution in predicting psychosocial adjustment to pain using confirmatory factor analysis; and (c) to explore the mediating effects of pain acceptance and cognitive defusion, comprising the "open" response style to pain, between pain interference and pain related outcomes. One hundred and sixty chronic pain patients completed a questionnaire packet including pain indexes, pain acceptance, cognitive fusion, avoidance, and emotional distress. Confirmatory factor analyses supported the 2-factor solution, though a general good model fit was achieved only for the short G-CPAQ version. Structural equation modeling showed that PW and AE coupled with cognitive defusion partially mediated the influence of pain interference on pain severity, emotional distress, and avoidance of pain.

Gain +1 or Avoid -1: Validation of the German Regulatory Focus Questionnaire (RFQ).

BACKGROUND: The Regulatory Focus Questionnaire (RFQ) assesses regulatory promotion and prevention focus, which represent orientations towards gains or losses. The main objective of this study was to examine the psychometric properties of the newly translated German version. METHODS: A sample of 1024 participants answered the questionnaire and several related instruments. We used an online survey tool to collect this data. Data analysis was conducted using methods of exploratory and confirmatory factor analysis in SPSS and AMOS. RESULTS: The RFQ displayed acceptable reliability, while its correlations with other, related psychological constructs indicated good validity. Factor analysis showed good fit for a two-dimensional model. Tests of measurement invariance revealed clear evidence for metric invariance while scalar invariance remained uncertain. Differences in regulatory focus based on sociodemographic characteristics are reported and discussed. CONCLUSIONS: Overall, the RFQ can be recommended for application in fields dealing with motivation and goal attainment in a broad sense.

Psychometric Properties of the German Version of the Health Regulatory Focus Scale.

The Health Regulatory Focus Scale (HRFS) is a short scale which measures an individual's prevention and promotion focus in a health-specific context. The main objective of this study was to examine the psychometric properties of the newly translated German version of the HRFS. Reliability and item characteristics were found to be satisfactory. Validity of both subscales toward other psychological constructs including behavioral approach and avoidance, core self-evaluations, optimism, pessimism, neuroticism, as well as several measures of physical and mental health was shown. In addition, invariance of the measure across age and gender groups was shown. Exploratory as well as confirmatory factor analyses clearly indicated a two-factorial structure with a moderate correlation between the two latent constructs. Differences in health promotion and prevention focus between socio-demographic groups are discussed. The HRFS is found to be a valid and reliable instrument for the assessment of regulatory focus in health-related environments.
