Social media addiction: associations with attachment style, mental distress, and personality.

BACKGROUND: Social media bring not only benefits but also downsides, such as addictive behavior. While an ambivalent closed insecure attachment style has been prominently linked with internet and smartphone addiction, a similar analysis for social media addiction is still pending. This study aims to explore social media addiction, focusing on variations in attachment style, mental distress, and personality between students with and without problematic social media use. Additionally, it investigates whether a specific attachment style is connected to social media addiction. METHODS: Data were collected from 571 college students (mean age = 23.61, SD = 5.00, 65.5% female; response rate = 20.06%) via an online survey administered to all enrolled students of Sigmund Freud PrivatUniversity Vienna. The Bergen Social Media Addiction Scale (BSMAS) differentiated between students addicted and not addicted to social media. Attachment style was gauged using the Bielefeld Partnership Expectations Questionnaire (BFPE), mental distress by the Brief Symptom Inventory (BSI-18), and personality by the Big Five Inventory (BFI-10). RESULTS: Of the total sample, 22.7% of students were identified as addicted to social media. For personality, it was demonstrated that socially media addicted (SMA) students reported significantly higher values on the neuroticism dimension compared to not socially media addicted (NSMA) students. SMA also scored higher across all mental health dimensions-depressiveness, anxiety, and somatization. SMA more frequently exhibited an insecure attachment style than NSMA, specifically, an ambivalent closed attachment style. A two-step cluster analysis validated the initial findings, uncovering three clusters: (1) secure attachment, primarily linked with fewer occurrences of social media addiction and a lower incidence of mental health problems; (2) ambivalent closed attachment, generally associated with a higher rate of social media addiction and increased levels of mental health problems; and (3) ambivalent clingy attachment, manifesting a medium prevalence of social media addiction and a relatively equitable mental health profile. CONCLUSIONS: The outcomes are aligned with previous research on internet and smartphone addiction, pointing out the relevance of an ambivalent closed attachment style in all three contexts. Therapeutic interventions for social media addiction should be developed and implemented considering these findings.

Cardiac contractility modulation: first experience in heart failure patients with reduced ejection fraction and permanent atrial fibrillation.

AIMS: Cardiac contractility modulation (CCM) is an electrical therapy for heart failure (HF) with reduced ejection fraction. Sinus rhythm is deemed necessary for effective treatment because the current CCM signal delivery algorithm requires sequential sensing of a p wave, followed by depolarizations at each ventricular lead. In case of atrial fibrillation (AF) CCM is inhibited. This study demonstrates the feasibility of CCM therapy in patients with permanent AF by circumventing the requirement for sensing of a natural p wave. METHODS AND RESULTS: Five CCM patients with AF received a pacemaker or implantable cardioverter/defibrillator (ICD) upgrade to cardiac resynchronization therapy (CRT) with low atrial sensitivity, which resulted in compulsory atrial stimulation followed by biventricular pacing. The CCM system recognized the atrial stimuli as p waves, which led to CCM signal delivery. Three patients developed permanent AF after a mean follow-up of 40 months of CCM therapy. Two patients had permanent AF at the time of CCM device implantation. All pacemaker or ICD devices were successfully upgraded to CRT. Cardiac resynchronization therapy stimulation rates of ≥96% and CCM stimulation rates between 60% and 95% were achieved. Clinical condition of the patients improved (mean NYHA class -0.7, left ventricular ejection fraction +2%, Minnesota living with HF questionnaire -15.6 points). CONCLUSION: CCM signal delivery is feasible in HF patients with permanent AF by sequential atrial-ventricular pacing, so that the atrial pacing spike is interpreted as a p wave by the CCM signal delivery algorithm. This experimental approach can be considered in individual cases. A new CCM algorithm, which does not require an atrial electrode, is desirable.

Risk and protection factors of mental stress among medical staff in the third year of the COVID-19 pandemic.

Background: The COVID-19 pandemic placed an extraordinary burden on health care workers (HCW), who are reported to suffer from great mental stress. The current study investigates the mental health of HCW in the later phases of the pandemic. Methods: HCW completed the following questionnaires online (06/2021-02/2022, N=159): demographics (age, gender, profession, ward), Impact of Event Scale (IES-R, posttraumatic stress), State Trait Anxiety Inventory (STAI-S, state anxiety), stress-coping questionnaire (SVF-78), and bespoke corona-specific stress and protective-factor questions (5 items each). We used factor analysis to test scale properties and regression-type methods (t-tests, ANOVA, multiple regression) for hypothesis tests and effect-size estimation. Results/discussion: Mental stress in HCW is influenced by similar factors as described for earlier phases. However, differences to earlier phases were found in ward affiliation which is no longer a variable of concern for explaining differences in mental health of HCW. Further, even if nurses are the occupational group with the highest mental stress as in prior research, detailed analysis shows that medical specialists with close proximity to patients with a high-level of responsibility are the most burdened sub-group. Unlike nurses, they suffer from high levels of anxiety in addition to high levels of post-traumatic and COVID-specific stress. Analyses showed further that COVID-specific stress is the strongest predictor of mental stress, wherein COVID-specific stress factors remain the same as reported in literature on the early pandemic phases. HCW showed to use still more positive than negative coping strategies. Negative strategies increased as expected mental stress, whereas positive strategies alleviated only anxiety. Additionally, we found that doctors benefited from many protective factors while nurses had access to fewer protective factors like earlier waves. Conclusion: Data show that HCW still suffer from mental stress in the third year of the pandemic. HCW of all hospital wards may be affected by mental stress and need attention and protective measures. Medical specialists are the most burdened subgroup. Detailed analyses show that properties other than occupation, gender, or ward affiliation are more appropriate to evaluate mental stress of HCW. The findings have implications for developing specialized protection strategies for the post-pandemic phase and future pandemics.

Prediction of experimental pain sensitivity by attention to pain-related stimuli in healthy individuals.

The aim of the present study was to assess the predictive power of the processing of pain-related information, comprising concepts of hypervigilance to pain, pain catastrophizing, and pain-related anxiety (questionnaires) as well as attentional processes related to pain-related stimuli (dot-probe task) in explaining individual differences in experimental pain sensitivity (pressure/thermal pain threshold). In 160 healthy participants (ages 13-61; 80 females), results of hierarchical multiple regression analyses showed that self-reported hypervigilance contributed significantly to the prediction of pain sensitivity, whereas pain catastrophizing and anxiety did not. However, inconsistent with prediction, the effect was in the opposite direction, indicating that vigilance to pain sensations or stimuli is associated with lower pain sensitivity in healthy individuals. Entering the attentional bias indices from the dot-probe task showed that an increased bias to pain words is related to higher experimental pain sensitivity, which confirms the hypothesis.

Effects of context and individual predispositions on hypervigilance to pain-cues: an ERP study.

BACKGROUND: Hypervigilance to pain is the automatic prioritization of pain-related compared with other stimuli. The processing of threat information is influenced by negative contexts. Therefore, we intended to explore such context effects on hypervigilance to pain-cues, taking individual differences in self-reported vigilance to pain into consideration. METHODS: In all, 110 healthy subjects viewed task-irrelevant emotional facial expressions (anger, happy, neutral, and pain) overlaid in half of the trials with a fine grid. The instructed task was to indicate the presence/absence of this grid. A threatening context was established by applying electrical stimuli slightly below pain-threshold. Using scores of Pain Vigilance and Awareness Questionnaire, the sample was divided into high vs low pain vigilant subjects. Reaction times and event-related brain potentials were recorded. RESULTS: No distinct attentional processing of pain faces (based on the event-related brain potentials) was observed as a function of high levels of self-reported vigilance to pain and contextual threat induction. High pain vigilant subjects showed generally enhanced processing of emotional and neutral faces as indicated by parameters of early (early posterior negativity) and late (late positive complex) processing stages. This enhancement was abolished when electro-stimuli were presented. CONCLUSION: Contextual threat does not enhance the attentional capture of pain-cues when they are presented concurrently with competing task demands. The study could, however, replicate a generally enhanced attentional processing of emotional cues in high pain vigilant subjects. This underpins that hypervigilance to pain is related to changes in emotional processing.

Efficacy and survival in patients with cardiac contractility modulation: long-term single center experience in 81 patients.

AIMS: To analyze long-term efficacy and survival in patients with chronic heart failure treated with cardiac contractility modulation. METHODS: 81 patients implanted with a CCM device between 2004 and 2012 were included in this retrospective analysis. Changes in NYHA class, ejection fraction (EF), Minnesota Living with Heart Failure Questionnaire, NT-proBNP and peak VO2 were analyzed during a mean follow up of 34.2 ± 28 months (6-123 months). Observed mortality rate was compared with that predicted by the MAGGIC Score. RESULTS: Patients were 61 ± 12 years old with EF 23 ± 7%. Heart failure was due to ischemic (n=48, 59.3%) or idiopathic dilated (n=33, 40.7%) cardiomyopathy. EF increased from 23.1 ± 7.9 to 29.4 ± 8.6% (p<0.05), mean NT-proBNP decreased from 4395 ± 3818 to 2762 ± 3490 ng/l (p<0.05) and mean peak VO2 increased from 13.9 ± 3.3 to 14.6 ± 3.5 ml/kg/min (p=0.1). The overall clinical responder rate (at least 1 class improvement of NYHA within 6 months or last follow-up) was 74.1%. 21 (25.9%) patients died during follow up, 11 (52.4%) due to cardiac conditions and 10 (47.6%) due to non-cardiac conditions. Mortality rates at 1 and 3 years were 5.2% and 29.5% compared to mortality rates estimated from the MAGGIC risk score of 18.4% (p<0.001) and 40% (p=ns), respectively. Log-Rank analysis of all events through 3 years of follow-up, however, was significantly less than predicted (p=0.022). CONCLUSIONS: CCM therapy improved quality of life, exercise capacity, NYHA class, EF and NT-proBNP levels during long-term follow up. Mortality rates appeared to be lower than estimated from the MAGGIC score.

Different stages in attentional processing of facial expressions of pain: a dot-probe task modification.

UNLABELLED: The way in which individuals attend to pain-related stimuli is thought to affect their pain experience. Early and late stages of processing, with shifts from attentional engagement to disengagement (avoidance), have been identified, but rarely investigated in the same protocol. Therefore, the present study aimed to consider 2 time frames that might be indicative of attentional engagement and disengagement. One hundred pain-free individuals performed a modified dot-probe task with pictorial stimuli displaying affective facial expressions (ie, pain, anger, joy, neutral face), presented either for 100 ms or for 500 ms. Because fear of pain has been found to moderate attentional processing of pain stimuli, the Fear of Pain Questionnaire (FPQ III) was also administered. Results indicated both early attentional engagement and later disengagement (avoidance) for negative facial expressions (anger, pain). This pattern was most prominent for pain faces and among those participants high in pain-related fear. Taken together, these findings provide evidence that the dot-probe task is suitable to investigate different stages of attentional processing for pain-related stimuli. In accordance with the vigilance-avoidance hypothesis, pain-related stimuli seem to attract attention quickly, but attentional avoidance may occur shortly after. PERSPECTIVE: We focused on different stages of attentional processing of pain faces in pain-free individuals. Results highlight the importance of distinguishing between early (engagement) and later (disengagement) components of attention, as well as considering the role that fear of pain has in understanding the nature of these effects.

Does vigilance to pain make individuals experts in facial recognition of pain?

BACKGROUND: It is well known that individual factors are important in the facial recognition of pain. However, it is unclear whether vigilance to pain as a pain-related attentional mechanism is among these relevant factors. OBJECTIVES: Vigilance to pain may have two different effects on the recognition of facial pain expressions: pain-vigilant individuals may detect pain faces better but overinclude other facial displays, misinterpreting them as expressing pain; or they may be true experts in discriminating between pain and other facial expressions. The present study aimed to test these two hypotheses. Furthermore, pain vigilance was assumed to be a distinct predictor, the impact of which on recognition cannot be completely replaced by related concepts such as pain catastrophizing and fear of pain. METHODS: Photographs of neutral, happy, angry and pain facial expressions were presented to 40 healthy participants, who were asked to classify them into the appropriate emotion categories and provide a confidence rating for each classification. Additionally, potential predictors of the discrimination performance for pain and anger faces - pain vigilance, pain-related catastrophizing, fear of pain--were assessed using self-report questionnaires. RESULTS: Pain-vigilant participants classified pain faces more accurately and did not misclassify anger as pain faces more frequently. However, vigilance to pain was not related to the confidence of recognition ratings. Pain catastrophizing and fear of pain did not account for the recognition performance. CONCLUSIONS: Moderate pain vigilance, as assessed in the present study, appears to be associated with appropriate detection of pain-related cues and not necessarily with the overinclusion of other negative cues.

Vigilance for pain-related faces in a primary task paradigm: an ERP study.

BACKGROUND: Pain-related stimuli are supposed to be automatically prioritized over other stimuli. This prioritization has often been tested using primary task paradigms in which pain information is irrelevant for completing the explicitly posed task. Task-irrelevant stimuli are only processed if they are very salient, and pain-related stimuli are assumed to be salient enough. OBJECTIVE: We wanted to further investigate this assumption by assessing event-related brain potentials (ERPs) - a very sensitive method for studying attention and reaction times in response to pictures of people in pain and other emotional faces - using a primary task paradigm. In addition, we assumed that individuals describing themselves as vigilant to pain are especially responsive to pain cues. METHODS: One hundred pain-free subjects were tested in a primary task paradigm using pictures of facial expressions of pain, anger, happiness, and neutral mood. ERPs were assessed at midline electrodes. Vigilance to pain was assessed by the pain vigilance and awareness questionnaire. RESULTS: In contrast to previous studies (which have used pain words), effects of facial expressions of pain and other emotions on the ERPs and reaction times were surprisingly weak throughout and did not give evidence for a distinct processing of pain-related stimuli. However, hypervigilant subjects appeared to be strongly and cognitively absorbed by all emotional stimuli. CONCLUSION: Accordingly, it appears that pain-related stimuli are not always of outstanding salience, but that certain characteristics (eg, type of material, emotional richness) have to be present, for pain-related stimuli to be prioritized over stimuli of other emotional content. Hypervigilance to pain may generally predispose individuals to process emotional stimuli in greater depth.
