Distress tolerance and lifetime frequency of non-suicidal self-injury (NSSI): A systematic review and meta-analysis.

NSSI has recently been recognized as a significant health issue given its documented association with psychopathology and across a broad spectrum of psychiatric disorders. It has been found that individuals experiencing heightened emotions, which is referred to as an emotional cascade, are more likely to engage in self-injury behaviour due to low levels of distress tolerance (DT). The current meta-analysis using PRISMA guidelines sought to quantify the strength of the association between DT and lifetime frequency of NSSI using 22 eligible studies (N = 14,588; F = 60.7%; age = 23.35 ± 7.30), mainly from the United States. The correlation between emotional DT and NSSI was a small negative correlation (r = -.14), and it was non-significant for behavioural DT and NSSI (r = .02). Also, the effect-size was significant for studies that used interview-based measure of NSSI (r = -.24), and it was non-significant when self-report measures of NSSI (r = -.11) utilized. The association between DT and NSSI was significant and negative across the general population (r = -.47), university students (r = -.17), and inpatients (r = -.27); surprisingly, it was significant and positive among adolescents or high school students (r = .17). The observed effect-sizes were independent of publication year, mean age and its standard deviation, study quality, female proportion, DT, NSSI measures reliability, and clinical status. Future studies on NSSI should consider DT as a spectrum from distress intolerance to distress over-tolerance, given that it seems it has different functions when different samples (e.g., adolescents) are studied.

Aripiprazole and its adverse effects in the form of impulsive-compulsive behaviors: A systematic review of case reports.

Aripiprazole is an efficacious treatment for both the positive and negative symptoms of schizophrenia and is also commonly used as a mood stabilizer. It is associated with better tolerability compared with other antipsychotics. However, there are reports of patients who experience problem gambling, hypersexuality, obsessive-compulsive symptoms, and other impulsive and/or compulsive behaviors as a result of aripiprazole administration and/or dosage increase. We aimed to do a systematic review of case reports published in this regard. After screening more than 6000 titles and abstracts in ten scientific search engines, we found 35 related records comprising 59 cases. The majority of cases (n = 42, 71.18%) were male, the mean age was 33.83 years (± 13.40), and the average daily dose of aripiprazole was 11.63 mg (± 6.94). The results of our review showed that the most frequently published impulsivity adverse effect of aripiprazole is gambling, followed by hypersexuality, obsessive-compulsive symptoms/disorder, problem eating, trichotillomania, problem shopping, and kleptomania. These symptoms were experienced both by patients who had previous problems in these areas and those who did not. In the majority of cases, the symptoms appeared within 30 days after aripiprazole administration started and ceased within 30 days of its discontinuation and/or dose decrease. Clinicians should be aware of impulsivity adverse effects, monitor them, and educate both patients and the family about them.

Effectiveness of transcutaneous vagus nerve stimulation (tVNS) on salicylate-induced tinnitus.

INTRODUCTION: Tinnitus is the most common symptom of auditory system disorders. It affects the quality of life of millions of people, but it is still incurable in most cases. Vagus nerve stimulation (VNS) therapy is a potential new treatment for subjective tinnitus. In this study, transcutaneous vagus nerve stimulation (tVNS) combined with tones was utilized to treat salicylate-induced tinnitus since salicylate is a reliable and convenient approach for rapidly inducing tinnitus. METHODS: Wistar rats were divided into acoustic stimulation alone (AS, n = 6), tVNS alone (n = 6), and tVNS with AS (n = 6) groups for behavioral and electrophysiological tests. They were assessed by auditory brainstem response (ABR), prepulse inhibition (PPI), gap prepulse inhibition of the acoustic startle (GPIAS), social interactions, and aggressive behavior tests at baseline and seven days' post-salicylate (175 mg/kg, twice a day) injection. RESULTS: The inhibition percentage of the GPIAS test was significantly reduced post-salicylate injection in the tVNS and AS alone groups, while it was not significant in the tVNS with AS group. There was no significant difference in the mean percentage of the GPIAS test between the tVNS groups (with or without AS) after salicylate injections. Social interactions were significantly different in the AS alone group pre- and post-salicylate injections, but they were not significant in other groups. Moreover, the results of aggressive behavior tests showed significantly increased post-salicylate injections in the AS alone group, while they were not significant in the tVNS groups (with or without AS). CONCLUSIONS: The current study revealed that the application of tVNS alone produced improved social interaction and mood and alleviated salicylate-induced tinnitus severity. Moreover, combining tVNS with acoustic stimulation can prevent salicylate-induced tinnitus.

Comparing Auditory Brain Stem Responses and Transient Otoacoustic Emissions in Premature Infants with Auditory Developmental Delay: Evidence of Temporary Auditory Neuropathy.

Objectives: Premature birth causes some permanent or temporary abnormalities in the hearing system of the newborn. Inadequate development of the central auditory nervous system and balance, as well as the delay in the formation of the nerve myelin, can be the cause of many hearing disorders, including permanent or temporary auditory neuropathy spectrum disorder (ANSD). The present study aims to identify and understand developmental delay disorder in the hearing system of infants and investigate the possibility of temporary auditory neuropathy in infants. Materials & Methods: In this comparative analytical study, twenty premature infants were randomly selected for hearing tests using auditory brainstem response and transient otoacoustic emissions at the time of discharge and three months after the first evaluation. The different components of these tests were analyzed and compared before and after developing the auditory system. Results: The OAEs test showed a signal-to-noise ratio above six dB with appropriate amplitudes in all infants. The grand average waveform of the ABR showed a significant difference between the amplitudes of waves III and V before and after maturation in both ears (p<0.05). In addition, the absolute latency of waves, specifically III and V, showed a significant difference between the two assessment times (0.05). Conclusions: The present study confirmed the occurrence of temporary ANSD or delayed maturation in premature infants following the lack of complete growth and myelination of auditory nerve fibers. There is a need to determine the hearing status of premature infants by frequent examinations and prevent any unnecessary prescription of amplifications.

Effect of Cognitive Rehabilitation by Auditory Stroop Training on Quality of Life of Individuals with Tinnitus.

Background: Studies have shown that tinnitus patients have difficulties in cognitive function such as memory and attention. The Stroop task engages the attention network where one aspect of the stimulus is noticed while the other one is ignored. Thus, Stroop training can improve the patient's cognitive control and ability to ignore the tinnitus signal. Method: Thirty chronic tinnitus (> 6 months) patients were included in this study. They were distributed into two 15-member groups: intervention and control. Common audiometric, psychometric, and psychoacoustic evaluations of tinnitus were performed for two groups before intervention and after auditory Stroop training of group 1. Results: There was significant difference in the quality of life and THI scores, VAS of annoyance, and reaction time of Stroop task before and after intervention in group1. The decreased reaction time was positively correlated with improved quality of life, THI score, and VAS of annoyance. Conclusion: Cognitive rehabilitation using tasks such as auditory Stroop can be effective in controlling tinnitus by improving cognitive control.

Romberg Neck Torsion :A New Specific Test for Cervicogenic Dizziness.

AIMS: Previous studies have shown that Cervical myofascial pain syndrome with dizziness (CMPS-D ) is one of the most common causes of cervicogenic dizziness and is associated with challenge in diagnosis and treatment. this study aimed to investigate the Romberg neck torsion test in patients with CMPS-D and healthy controls. MATERIALS AND METHODS: Cross-sectional, observational study. twenty patients with CMPS-D were compared with twenty healthy controls. the Romberg (neutral position and neck torsion) and smooth pursuit neck torsion tests were performed in patients with CMPS-D and healthy controls. RESULTS: The results confirmed that there are significant differences in the Romberg neck torsion test between subjects with CMPS-D and healthy controls (p < 0.05). in addition, There was a significant correlation between Romberg neck torsion and smooth pursuit neck torsion results (p < 0.05). CONCLUSION: The results of Romberg neck torsion test in CMPS-D subjects were different from those in healthy controls, which was attributed to neck pain and changes in cervical proprioception input. Romberg neck torsion is a new method for assessing cervicogenic dizziness.

Atypical function of auditory sensory gating in children with developmental dyslexia: Investigating its relationship with cognitive abilities.

Impairments of auditory processing are among frequent findings in dyslexia. However, it is unclear how auditory signals are gated from brainstem to higher central processing stages in these individuals. The present study was done to investigate auditory sensory gating in children with developmental dyslexia (DD), and to determine whether sensory gating correlates with performance on behavioural tasks. Auditory sensory gating at P50, N1 and P2 waves was evaluated in two groups including 20 children with DD and 19 children with typical reading development (TRD). Behavioural tests were used to evaluate phonological working memory (PWM) and selective attention abilities. Sensory gating in children with DD was significantly less efficient than their peers at P50, N1 and P2 waves. Lower auditory evoked potential (AEP) amplitudes were found in the DD group. The children with TRD scored better in all the behavioural tests. Relationships were reported between sensory gating at P50, N1, P2 and behavioural performance in the two groups. Children with dyslexia had deficient sensory gating in comparison with controls. In addition, children with dyslexia experienced problems with PWM and selective attention tasks. The function of sensory gating was associated with attentional and PWM performances in this group.

Has the prevalence of problematic social media use increased over the past seven years and since the start of the COVID-19 pandemic? A meta-analysis of the studies published since the development of the Bergen social media addiction scale.

Problematic Social Media Use (PSMU) has been defined as the lack of regulation of one's use of social media associated with negative outcomes in everyday functioning. Previous meta-analyses reported PSMU prevalence before the beginning of the COVID-19 pandemic and based the estimates on the cut-off scores, which are debatable in the current fields. The present meta-analysis aims to explore whether PSMU, as assessed by the most used self-report scale (i.e., the Bergen Social Media Addiction Scale; BSMAS), increased across the world (i) since the first published study on this topic (i.e., in the last seven years), (ii) since the beginning of the COVID-19 pandemic, and (iii) depending on age, gender and the income level of the countries. The meta-analysis involved 139 independent samples with 133,955 respondents from 32 countries spanning seven world regions. The results show that PSMU: (i) is significantly higher in low-income countries (LIC); (ii) did not increase in the last 7 years overall and after the beginning of the COVID-19 pandemic, except for LIC; (iii) did not vary depending on age and gender. The higher prevalence of PSMU reported during the COVID-19 pandemic by some single studies may have been a transient phenomenon to cope with physical distances in some countries, whilst, in others, an overall increase of PSMU occurred. High levels of PSMU in LIC might be explained based on socio-cultural differences between countries, but also with the higher prevalence of mental disorders in LIC since PSMU might be a symptom of other, more primary psychiatric disorders.

An assessment of the psychometric properties and psychological correlates of the Greek COVID-19 Anxiety Syndrome Scale (C-19ASS).

In Greece, the COVID-19 pandemic was associated with social isolation, economic crisis, considerable unemployment, and an escalation of psychological distress. Given the potential of COVID-19 to engender a long-lasting impact on mental health, validating the COVID-19 Anxiety Syndrome Scale (C-19ASS) may be beneficial in determining if fear-based behaviors may persist post-pandemic. This is a psychometric study examining the C-19ASS features across a general sample of Greeks (n = 912; female = 78%; mean age = 32.35, ±9.25). The Greek C-19ASS demonstrated a two-factor structure consistent with the original scale's perseveration and avoidance subscales. This structure was supported by confirmatory factor analysis, which demonstrated a strong fit and robust reliability along with good divergent and convergent validity evidenced by correlational analyses. The incremental validity test revealed that the Greek C-19ASS predicted functional impairment and COVID-19 anxiety independently of health anxiety, generalized anxiety, and depressive symptoms, the Big Five personality traits, pandemic-related factors, and demographic variables. The findings were discussed using a self-regulatory executive function model as a theoretical background to discuss this pandemic-related phenomenon.

Problematic smartphone use and sleep disturbance: the roles of metacognitions, desire thinking, and emotion regulation.

Background: The association between problematic Smartphone use (PSU) and sleep disturbance is evidenced in the literature, but more research is required to investigate the potential factors that may influence the effect of PSU on sleep disturbance. Given the considerable prevalence of PSU (9.3 to 36.7%) and sleep disturbance (55.2%) in Iran, the current study sought to examine an interactional model to test whether metacognitions about Smartphone use, desire thinking (verbal perseveration and imaginal prefiguration), and emotion regulation (expressive suppression and cognitive reappraisal) could have a moderating effect on the above-mentioned association. Method: This present study is a cross-sectional, observational study that was conducted between June and September 2022 in a convenience sample of Iranians (n = 603, Female = 419, Age = 24.61 ± 8). Results: Despite the significant association between metacognitions about the Smartphone use, PSU, and sleep disturbance, metacognitions failed to predict sleep disturbance above PSU. A slope analysis showed, however, that a high (not low or moderate) levels of imaginal prefiguration strengthen the association between PSU and sleep disturbance, while a high (not low or moderate) level of cognitive reappraisal and expressive suppression dampen the PSU-sleep disturbance association. We also found that verbal perseveration and expressive suppression were unique predictors of sleep disturbance, while imaginal prefiguration and reappraisal only predicted sleep disturbance if they interacted with PSU. Conclusion: Theoretically, findings suggest that enhancing cognitive reappraisal (by 1 SD) and reducing imaginal prefiguration (by 1 SD), might protect against sleep disturbance by reducing its association with PSU. Limitations and future directions are discussed.

Association between Simultaneous Occurrence of Occupational Noise-Induced Hearing Loss and Noise-Induced Vestibular Dysfunction: A Systematic Review.

Background: Background: Because of functional and structural similarities between the cochlea and vestibular sensory receptors, vestibular dysfunction could be accompanied by noise-induced hearing loss (NIHL) due to occupational noise exposure. We aimed to evaluate the occurrence of vestibular dysfunction (VD) in individuals with NIHL and occupational noise exposure. Methods: A systematic literature research was carried out within the databases of PubMed, Scopus, Science Direct, and Web of Science for published articles between 1980 and Jan 5, 2023 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The methodological quality of the included systematic reviews was assessed with the Joanna Briggs Institute (JBI) checklist. Vestibular system dysfunction parameters were considered as primary outcomes in subjects with NIHL. Results: We reviewed the evidence (from 19 eligible articles) for VD from noise-induced damage to peripheral vestibular structures. VD can occur after occupational noise exposure or concomitantly with NIHL. Furthermore, this study showed that the saccular organ has a higher susceptibility to noise damage than the vestibular organs of the utricle and semicircular canals (SCCs). Conclusion: Our results support the role of occupational noise exposure and NIHL as risk factors for developing VD. Further research is needed to investigate the association between the occurrence of VD due to occupational noise exposure or concomitantly with NIHL.

Potential risk and protective factors related to problematic social media use among adolescents in Iran: A latent profile analysis.

This study aimed to assess Problematic Social Media Use (PSMU) among Iranian adolescents and explore potential risk and protective factors. In the present cross-sectional study, 3375 Iranian adolescents were recruited online and completed questionnaires. Latent profile analysis (LPA) was performed to identify groups with various levels of PSMU. Indicator variables included standardized factor scores for PSMU, attention-deficit/hyperactivity disorder, sensation-seeking, internet addiction, loneliness, social anxiety, internalizing symptoms, social support and self-esteem. Five groups were identified relating to severities of PSMU and other factors: low-risk: n = 823 (24.4 %); low-to-moderate-risk: n = 835 (24.7 %); moderate-risk: n = 630 (18.7 %); moderate-to-high-risk: n = 584 (17.3 %); high-risk: n = 503 (14.9 %). Multiple factors, including sensation-seeking, internalizing symptoms, social anxiety, loneliness, internet addiction, attention-deficit/hyperactivity disorder, low self-esteem and low perceived social support, statistically predicted PSMU. The current findings may help identify Iranian adolescents who are particularly vulnerable to PSMU and assist in intervention development.

Psychometric properties and measurement invariance across gender of the Compulsive Online Shopping Scale (COSS) among Iranians.

The present study aimed to investigate the psychometric properties and measurement invariance of the Compulsive Online Shopping Scale (COSS) in an Iranian population. The total sample of 802 participants (257 females; Mean age = 22.27, SD = 2.83) were selected via convenience sampling from Tehran, Iran. Confirmatory Factor Analysis supported the 7-factor structure of the COSS as proposed in the original study. The measurement invariance found in this study suggests that the COSS provides sufficiently unbiased use among males and females. The current findings also support the concurrent validity of the Persian COSS, which exhibited positive and significant associations with loneliness, impulsivity, obsession, internalized symptoms, and Internet use. Furthermore, results confirm the convergent validity of the Persian COSS and showcased acceptable internal consistency for all factors, and the total score. The findings of the present study indicate that compulsive online shopping could be assessed adequately in Iranian samples using the COSS.

In silico analysis of sporozoite surface antigen 1 of Theileria annulata (TaSPAG1) for multi-epitope vaccine design against theileriosis.

Tropical theileriosis is a protozoan infection caused by Theileria annulata, which significantly affects cattle worldwide. This study was aimed to analyze the TaSPAG1 protein and design a novel multi-epitope vaccine candidate. Online tools were employed for the prediction of Physico-chemical properties, antigenicity, allergenicity, solubility, transmembrane domains and signal peptide, posttranslational modification (PTM) sites, secondary and tertiary structures as well as intrinsically disordered regions, followed by identification and screening of potential linear and conformational B-cell epitopes and those peptides having affinity to bind bovine major histocompatibility complex class I (MHC-I) molecules. Next, a multi-epitope vaccine construct was designed and analyzed. This 907-residue protein was hydrophilic (GRAVY: -0.399) and acidic (pI: 5.04) in nature, with high thermotolerance (aliphatic: 71.27). Also, 5 linear and 12 conformational B-cell epitopes along with 8 CTL epitopes were predicted for TaSPAG1. The 355-residue vaccine candidate had a MW of about 35 kDa and it was antigenic, non-allergenic, soluble and stable, which was successfully interacted with cattle MHC-I molecule and finally cloned into the pET28a(+) vector. Further wet studies are required to assess the vaccine efficacy in cattle. Supplementary Information: The online version contains supplementary material available at 10.1007/s40203-023-00153-5.

Psychometric properties and psychological correlates of the COVID-19 Anxiety Syndrome Scale: A comprehensive systematic review and meta-analysis.

Coronavirus disease-19 (COVID-19) has led to the demise of millions of people worldwide; additionally, it has resulted in a significant economic and mental health burden. Since the onset of the COVID-19 pandemic, various measures have been constructed to evaluate pandemic-related fear and anxiety. The COVID-19 Anxiety Syndrome Scale (C-19ASS) is a promising measure that assesses coping strategies (e.g., avoidance, checking, worrying and threat monitoring), termed 'COVID-19 Anxiety Syndrome', in response to COVID-19 fear and anxiety. The measure has been broadly welcomed, leading to its use in Brazil (Portuguese), China, Greece, Indonesia, the Philippines, Iran (Farsi), Italy, Saudi Arabia (Arabic), Turkey, the United Kingdom and the United States. To gain a better understanding of the relevance of the COVID-19 Anxiety Syndrome, we conducted a systematic review and meta-analysis to explore the psychological correlates and psychometric properties of the C-19ASS. Through the analysis of a total of 17,789 individuals (age range 19-70; female = 33%-85%), the C-19ASS demonstrated a consistent factor structure, measurement invariance across gender and acceptable reliabilities. Furthermore, a significant association with COVID-19 anxiety, depressive symptoms, generalized anxiety, health anxiety, psychological distress and functional impairment (work and social adjustment) during the COVID-19 pandemic was observed. When considering the Big Five personality traits, the C-19ASS and its subscales were only significantly and negatively associated with extraversion; only the total score on the measure was associated with neuroticism. The observed effect sizes ranged from very small to medium. Given that all included studies (K = 24) were cross-sectional, and due to the nature of the COVID-19 Anxiety Syndrome, which may well persist after the pandemic ends, it is recommended to continue screening society for the persistence of this syndrome.

The Auditory Brainstem Response (ABR) Test, Supplementary to Behavioral Tests for Evaluation of the Salicylate-Induced Tinnitus.

Tinnitus is a symptom of various disorders that affects the quality of life of millions people. Given the significance of the access to an objective and non-invasive method for tinnitus detection, in this study the auditory brainstem response (ABR) electrophysiological test was used to diagnose salicylate-induced tinnitus, in parallel with common behavioral tests. Wistar rats were divided into saline (n = 7), and salicylate (n = 7) groups for behavioral tests, and salicylate group (n = 5) for the ABR test. The rats were evaluated by pre-pulse inhibition (PPI), gap pre-pulse inhibition of the acoustic startle (GPIAS), and ABR tests, at baseline, 14 and 62 h after salicylate (350 mg/kg) or vehicle injection. The mean percentage of GPIAS test was significantly reduced following salicylate administration, which confirms the induction of tinnitus. The ABR test results showed an increase in the hearing threshold at click and 8, 12, and 16 kHz tones. Moreover, a decline was observed in the latency ratio of II-I waves in all tone burst frequencies with the highest variation in 12 and 16 kHz as well as a decrement in the latency ratio of III-I and IV-I only in 12 and 16 kHz. ABR test is able to evaluate the salicylate induced tinnitus pitch and confirm the results of behavioral tinnitus tests. GPIAS reflexive response is dependent on brainstem circuits and the auditory cortex while, ABR test can demonstrate the function of the auditory brainstem in more details, and therefore, a combination of these two tests can offer a more accurate tinnitus evaluation.

Combined Bifrontal Transcranial Direct Current Stimulation and Auditory Stroop Training in Chronic Tinnitus.

Patients with tinnitus experience difficulties in cognitive control and executive functions. Many of which are regarded as the cause of tinnitus rather than its complications. Methods for the improvement of inhibitory and cognitive control seem to be effective in the control of tinnitus. In this study, transcranial direct current stimulation and auditory Stroop exercise were have been to improve inhibitory control and the ability to ignore tinnitus in patients suffering from chronic tinnitus. 34 patients with chronic tinnitus (> 6 months) were randomly divided into two groups. The first group consist of 17 patients who received 6 sessions of tDCS followed by 6 sessions of auditory Stroop training. The second group received 6 sessions of sham tDCS followed by 6 sessions of auditory Stroop training. The initial evaluations including pure tone audiometry, psychoacoustic measurements, tinnitus handicap inventory (THI) survey and visual analog scale (VAS) of annoyance and loudness were performed before, immediately after, and one month after the tDCS, sham, and Stroop training. The results of this study revealed a significant reduction in THI score, VAS of loudness, and annoyance of tinnitus. A significant correlation was detected between the reaction time of incongruent words in the Stroop task and improvement of THI score and VAS of annoyance. Combined tDCS and Stroop training efficiently improve chronic tinnitus.

The influence of home and environmental characteristics on 5-18 years old children's health during the COVID-19 pandemic: A cross-sectional study in Iran.

Background: The coronavirus disease (COVID-19) pandemic has dramatically changed the health and wellbeing of children. Therefore, this study aimed to investigate the relationship between the home environment and the environmental characteristics on 5-18 years old children health in Iran. Method: An online survey was conducted among parents of children aged 5 to 18 living in large cities in Iran in 2021. The statistical population of this cross-sectional study was 500 people. In this survey, questionnaires on the quality of the home environment, exterior and interior landscapes of homes, and the Child Health Questionnaire (CHQ) were used to investigate the relationship between the home environment and environmental characteristics on 5-18 years old children health during the COVID-19 pandemic. The t-test and analysis of variance were used in SPSS 24, and the structural equation modeling (SEM) was utilized in AMOS 24 for analyzing the data. Results: The average age of respondents was 37.13 ± 7.20, and that of children was 11.57 ± 3.47. 73.02% of the families were covered by insurance, and 74.08% of them lived in the metropolis. In addition, 65.04% of the families complied with the restrictions of the quarantine period. A share of 31% of the families live in villas, and 55% paid more attention to cleaning their homes during the COVID-19 pandemic than before. A positive and significant statistical relationship (ß = 0.414, p < 0.001) was observed between the residence environment and child health. Thus, explained 17.5% of variations in child health. Conclusion: The results showed that the children who lived in homes with an exterior landscape in nature had better health. In addition, the 5-18 years old children whose home landscape was a garden, compared to the other two groups (yard, balcony), had better health. Gardens are a potential source of health and not necessarily replaced by other natural environments, thus providing them along with green space is one of the crucial issues that should be considered.

The Big-five personality traits and their link to problematic and compensatory Facebook use: A systematic review and meta-analysis.

Social networking sites are widespread worldwide, and Facebook is the leading platform in terms of the number of users, laying the ground for potential problematic use. However, problematic Facebook use does not occur for most users but only for a minority. Previous research has found an association between the Big-five personality traits and problematic Facebook use, but the direction of these associations remains controversial. We aimed to fill this gap in knowledge through a systematic review and meta-analysis comprising 425 effect-sizes (78 studies) and 39,930 individuals (females = 33 % to 89 %; age range = 17 to 48 years). Extraversion and neuroticism were associated with higher daily and weekly hours spent on Facebook, while conscientiousness was negatively associated with higher daily hours and not weekly hours. However, when time spent on Facebook was assessed by validated questionnaires, different patterns of associations were observed. Except for the non-significant role of extraversion, the other personality traits were negatively associated with problematic Facebook use, while neuroticism was positively associated. When using different assessment tools was considered, extraversion remained non-significant, but different association patterns were observed. Moreover, for compensatory Facebook use, all personality traits were negatively associated with it, whereas neuroticism exhibited a positive association. Different patterns of associations in terms of strength and direction were observed depending on samples and measures characteristics; thus, definitive conclusions on the direction of the associations are impossible to draw at present. A more robust conceptualization and assessment of problematic Facebook use, as well as time spent on it, is required. Implications, limitations, and future directions are discussed.

Metacognitions About Health in Relation to Coronavirus Anxiety: The Mediating Role of Cognitive Attentional Syndrome and Distress Tolerance.

The current study aimed to investigate the mediating role of cognitive attentional syndrome (CAS) and distress tolerance in the relationship between health-related metacognitions and coronavirus anxiety. The sample of this study consisted of 462 participants (381 female). Participants voluntarily completed self-report questionnaires on each of the variables mentioned above. The results of the structural modeling analysis showed that health-related metacognitions have a significant effect on the mediator variable of distress tolerance and CAS. Also, health-related metacognitions had a direct effect on coronavirus anxiety. Also, based on the results of the bootstrap test, it can be argued that health-related metacognitive beliefs, apart from their direct effect, play an important role in coronavirus anxiety, with CAS acting as a mediator. This study provides insights into the relationships among metacognitive beliefs, coronavirus anxiety, CAS, and distress tolerance. In particular, dysfunctional metacognitive beliefs, including an individual's beliefs about the uncontrollability of disease-related thoughts, are risk factors that could negatively affect mental health, leading to coronavirus anxiety. In addition, the association of dysfunctional beliefs with maladaptive behaviors resulting from the cognitive attentional syndrome is also involved in predicting and causing coronavirus anxiety. Given the insignificant role of emotional distress tolerance in the psychopathology of COVID-19 anxiety, the findings emphasize the importance of cognitive factors in this context.
