Clinical Utility of Beck Anxiety Inventory in Clinical and Nonclinical Korean Samples

Initial updosing phase of oral immunotherapy improves quality of life and psychological burden in parents of children with food allergy

Background: Oral immunotherapy (OIT) can impose psychological burdens on patients and their parents due to the necessary preparations and repeated adverse reactions. Objective: To investigate changes in quality of life (QoL) and psychological burden in parents of children receiving OIT for food allergy (FA). Methods: Children aged 3-13 years with FA were enrolled. Parents were asked to fill out the Korean versions of the Food Allergy Quality of Life-Parental Burden (FAQL-PB), the Korean versions of the Food Allergy Quality of Life-Parental Form (K-FAQLQ-PF), the Korean versions of the Beck Anxiety Inventory (K-BAI), and the Korean version of the Patient Health Questionnaire-9 (PHQ-9) for depression before OIT (T1), after 2 months of updosing (T2), and after the end of the updosing phase (T3). Results: A total of 111 parents were enrolled. The total FAQL-PB scores were decreased at T2 and T3 compared with those at T1 (all p < 0.001). Greater improvement in the total FAQL-PB score at T2 was noted in parents with a higher parental burden (FAQL-PB score ≥ 74 points) at baseline than in those with a lower parental burden (p = 0.001). Among the K-FAQLQ-PF domains, "food anxiety" scores were decreased at T2 and T3 compared with those at T1 (p = 0.049 and p = 0.030, respectively), whereas there was no change in "social and dietary limitation" and "emotional impact" scores between T1 and T2 and between T1 and T3. However, no differences were observed in K-BAI and PHQ-9 scores between T1 and T2 and between T1 and T3. Conclusion: Our results suggest that OIT improves parental burden and QoL in parents of children with FA.

A Narrative Review of Self-Reported Scales to Evaluate Depression and Anxiety Symptoms in Adult Obstructive Sleep Apnea Patients

Background and Objectives: Obstructive sleep apnea (OSA) is a prevalent chronic condition that has been associated with mental disorders like depression and anxiety. This study intends to provide a practical overview of the most relevant self-reported and self-rating scales that assess depression and anxiety in OSA patients. Materials and Methods: A search for articles was performed using PubMed, Google Scholar, and Semantic Scholar using a combination of words for obstructive sleep apnea, depression, anxiety, and scales. The tools were ordered by type (screening and rating) and arranged chronologically according to the year of publication. Results: Three scales were identified for assessing depression, which were the Center for Epidemiologic Studies Depression Scale (CES-D), the Hospital Anxiety and Depression Scale (HADS-D), and the Patient Health Questionnaire-9 (PHQ-9). For rating depression, two scales were discussed: the Zung Self-Rating Depression Scale (SDS) and the Beck Depression Inventory (BDI), which has three versions (the BDI, the BDI-II, and the Fast Screen (BDI-FS)). For assessing anxiety, the Generalized Anxiety Disorder-7 (GAD-7) scale was identified. Two scales were reviewed for rating anxiety: the State-Trait Anxiety Inventory (STAI) and the Beck Anxiety Inventory (BAI). Each scale is accompanied by a brief description of its practicality and psychometric qualities and an analysis of its strengths and limitations. Conclusions: The findings of this review will contribute to the understanding of the importance of assessing mental health comorbidities in the context of OSA, ultimately guiding clinical practice and future research in this area.

Association between functional outcomes and psychological variables in persons with spinal cord injury

We aimed to explore the association of functional outcomes with psychological variables, including depression, anxiety, sleep quality, and suicide risk, in persons with spinal cord injuries (SCIs). The secondary aim was to determine specific functions related to the psychological variables. This retrospective study included 259 persons with SCIs who were admitted to the Korean National Rehabilitation Center between 2019 and 2021. The participants were interviewed by a psychiatrist and completed questionnaires, including the Korean Beck Depression Inventory II (K-BDI-II), Korean Beck Anxiety Index, Insomnia Severity Index, and Mini International Neuropsychiatric Interview. To assess functional outcomes, the Spinal Cord Independence Measure III (SCIM III) and Walking Index for Spinal Cord Injury were determined by a physical therapist. The findings revealed a negative correlation of SCIM III subdivisions 1 and 3 with K-BDI-II. Specifically, feeding and mobility in bed and actions to prevent pressure injuries were functional factors associated with all four psychological variables. Our findings can guide clinicians to focus on improving functional independence and activities of daily living during the management of persons with SCI to prevent psychological consequences. Developing devices that aid in improving functional independence is crucial and may improve psychological problems in such individuals.

Psychological Distress and Perceived Burden in Parents of Korean Children With IgE-Mediated Food Allergy

BACKGROUND

Food allergy (FA) can have a profound effect on quality of life (QoL), stress, and anxiety in the family. We aimed to validate the Korean version of the Food Allergy Quality of Life-Parental Burden (FAQL-PB) and identify factors related to the parental psychosocial burden of caring for children with FAs.

METHODS

Parents of children aged between 6 months and 17 years with immunoglobulin E (IgE)-mediated FAs from the Pediatric Allergy Department of five university hospitals in Korea were enrolled in the study. Parents were asked to complete the FAQL-PB, Food Allergy Independent Measure-Parent Form (FAIM-PF), Child Health Questionnaire-Parents Form 28 (CHQ-PF28), Beck's Anxiety Inventory, Connor-Davidson Resilience Scale, and Patient Health Questionnaire-9 for depression. Statistical analyses included internal consistency, test-retest reliability, concurrent validity, discriminative validity, and logistic regression analyses.

RESULTS

A total of 190 parents were enrolled. Social activity limitation was the item with the highest FAQL-PB scores. The Cronbach's α for each item was higher than 0.8. The test-retest reliability was good (intra-class correlation coefficient, 0.716; 95% confidence interval [CI], 0.100-0.935). An increase in the FAQL-PB was significantly associated with an increase in the FAIM-PF (β = 0.765, P < 0.001) (concurrent validity). There was a positive correlation between parental burden, anxiety, and depression, while resilience was inversely correlated with parental burden (all P < 0.001). The total FAQL-PB score in parents of children who had experienced anaphylaxis was significantly higher than that in parents of children who did not experience it (P = 0.008). When adjusting for age, sex, and underlying diseases, anaphylaxis (β = 9.32; 95% CI, 2.97 to 15.68), cow's milk (CM) allergy (β = 8.24; 95% CI, 2.04 to 14.44), soybean allergy (β = 13.91; 95% CI, 1.62 to 26.20), higher anxiety (β = 1.05; 95% CI, 0.07 to 1.41), higher depression (β = 2.15; 95% CI, 1.61 to 2.69), and lower resilience (β = -0.42; 95% CI, -0.61 to -0.2) were significantly associated with greater parental burden in children with IgE-mediated FAs.

CONCLUSION

FAQL-PB is a reliable and valid tool for use in Korea. Anaphylaxis, CM or soybean allergies, more anxiety and depression symptoms, and lower resilience are associated with poorer QoL in parents of children with FAs.

Association between gut microbiota and anxiety symptoms: A large population-based study examining sex differences

BACKGROUND

This study aimed to examine the association between anxiety symptoms and gut microbial composition and to infer their functional pathways.

METHODS

In total, 605 participants were included in this study. Participants were categorized into anxious and non-anxious groups according to their Beck Anxiety Inventory scores, and their fecal microbiota was profiled using 16S ribosomal RNA gene sequencing. The microbial diversity and taxonomic profiles of the participants with anxiety symptoms were analyzed using generalized linear models. The function of the gut microbiota was inferred by comparing 16S rRNA data between the anxious and non-anxious groups.

RESULTS

The gut microbiome of the anxious group showed lower alpha diversity than that of the non-anxious group, and there were prominent differences in the community structure of the gut microbiota between the two groups. Male participants with anxiety had lower relative abundances of the family Oscillospiraceae, fibrolytic bacteria including those of the family Monoglobaceae, and short-chain fatty acid-producing bacteria such as those of the genus Lachnospiraceae_NK4A136 than those without anxiety symptoms. Female participants with anxiety symptoms had a lower relative abundance of the genus Prevotella than those without anxiety symptoms.

LIMITATION

The direction of causality between anxiety symptoms and the gut microbiota was unclear owing to the cross-sectional design of the study.

CONCLUSION

Our results elucidate the association between anxiety symptoms and gut microbiota and provide insights for developing interventions to treat anxiety symptoms.

Examining the association between neuropsychiatric symptoms among people with dementia and caregiver mental health: are caregiver burden and affiliate stigma mediators?

BACKGROUND

Neuropsychiatric disturbances are common manifestations of dementia disorders and are associated with caregiver burden and affiliate stigma. The present study investigated affiliate stigma and caregiver burden as mediators for the association between neuropsychiatric symptoms of people with dementia (PWD) and caregiver mental health such as depression and anxiety.

METHODS

A cross-sectional survey study was carried out with 261 dyads of PWD and informal caregivers from the outpatient department of a general hospital in Taiwan. The survey included the Caregiver Burden Inventory (CBI), the Affiliate Stigma Scale (ASS), the Taiwanese Depression Questionnaire (TPQ), and the Beck Anxiety Inventory (BAI). Mediation models were tested using the Hayes' PROCESS macro (Model 4 for parallel mediation model; Model 6 for sequentially mediation model).

RESULTS

Caregiver burden, affiliate stigma, caregiver depression, and caregiver anxiety were significantly associated with neuropsychiatric symptoms. After controlling for several potentially confounding variables, it was found that PWD's neuropsychiatric symptoms, caregiver burden and affiliate stigma significantly explained 52.34% of the variance in caregiver depression and 37.72% of the variance in caregiver anxiety. The parallel mediation model indicated a significantly indirect path from PWD's neuropsychiatric symptoms to caregiver mental health through caregiver burden and affiliate stigma, while the direct effect was not significant. Moreover, there was a directional association between caregiver burden and affiliate stigma in the sequential mediation model.

CONCLUSIONS

These findings show that it is imperative to improve caregivers' perception of those with dementia to reduce internalized stigma and to improve caregivers' mental health. Implementation of affiliate stigma assessment in clinical practice would allow distinctions to be made between the impact of affiliate stigma and the consequences of caregiver burden to help inform appropriate intervention.

EEG-biomarker theta/beta ratio and attentional quotients in adults who stutter: An electrophysiological and behavioral study

INTRODUCTION

There is increasing evidence that connects developmental stuttering to attention. However, findings have represented contradiction. Therefore, this study was conducted to investigate the possible relationship between stuttering and attention in resting and undertask conditions.

METHODS

In a cross-sectional study, 26 right-handed AWS (adults who stutter) and 25 matched fluent speakers were enrolled. Demographic data were collected, and the Beck anxiety inventory (BAI) was filled out for all participants. Then, QEEG was conducted, followed by IVA2. CPT test for all subjects. Finally, data were analyzed using SPSS software version 16.

RESULTS

AWS indicated significantly weaker auditory focus attention in the task (p = .02) than the control group, while a similar resting-state EEG marker of attention was found between groups (p > .05). Moreover, attention was not correlated between the two conditions (p > .05).

CONCLUSION

The EEG marker of attention did not necessarily designate the attentional performance of AWS under the task. Furthermore, attentional skills could be considered in the assessment and therapeutic programs of at least some groups of AWS.

Clinical factors affecting depression in patients with painful temporomandibular disorders during the COVID-19 pandemic

Temporomandibular disorders (TMD) are a multifactorial condition associated with both physical and psychological factors. Stress has been known to trigger or worsens TMD. We aimed to investigate whether the novel coronavirus disease-2019 (COVID-19) pandemic aggravates depression in patients with painful TMD, and the factors that affect their level of depression. We included 112 patients with painful TMD (74 females, 38 males; mean age: 35.90 ± 17.60 years; myalgia [n = 38], arthralgia [n = 43], mixed joint-muscle TMD pain [n = 31]). TMD was diagnosed based on the Diagnostic Criteria for TMD Axis I. Physical pain intensity was recorded using the visual analog scale (VAS); psycho-emotional status (depression: Beck Depression Inventory [BDI], anxiety: Beck Anxiety Inventory [BAI], and generalized stress related to COVID19: Global Assessment of Recent Stress [GARS]) was investigated twice (before [BC] and after COVID-19 [AC]). Additionally, factors affecting BDI-AC were investigated. BDI (p < 0.001), BAI (p < 0.001), GARS (p < 0.001), and VAS (p < 0.01) scores were significantly increased at AC than BC. The depression, anxiety, and stress levels were significantly positively correlated, and the AC and BC values of each factor showed a high correlation. In the mixed TMD group, BDI-AC was positively correlated with VAS-AC (p < 0.001). In the multiple regression analysis, clenching habit was the strongest predictor of an increase in the BDI scores from moderate to severe, followed by psychological distress, muscle stiffness, female sex, BAI-AC, and TMJ sounds. COVID-19 has negatively affected the psycho-emotional state of patients with painful TMD, and several clinical factors, including female sex and clenching habits, have influenced depression.

Reliability and validity of the traditional Chinese version of the GAD-7 in Taiwanese patients with epilepsy

BACKGROUND

Generalized anxiety disorder (GAD) is the second most common psychiatric comorbidity of epilepsy. GAD has a negative impact on seizure control, and it is underrecognized. The Generalized Anxiety Disorder 7-item (GAD-7) questionnaire is useful for screening GAD in patients with epilepsy (PWE). This study aimed to validate the traditional Chinese version of the GAD-7 for Taiwanese patients by obtaining data on adult PWE from our hospital.

METHOD

PWE were recruited from the Taipei Veterans General Hospital from April 2017 to January 2020. The mood disorder module of the Mini International Neuropsychiatric Interview (MINI) was used for the psychiatric assessment. The traditional Chinese version of the GAD-7 and the Beck Anxiety Inventory were included as self-rated psychiatric evaluation. To investigate the psychometric properties, internal consistency, external validation, and receiver operator characteristic (ROC) curve analysis were conducted to assess the utility of the Taiwanese version of the GAD-7.

RESULTS

We recruited 109 patients in the present study. Seventeen patients (15.9%) had GAD according to the MINI. The mean GAD-7 score was 10.28 ± 10.68. All the GAD-7 items were significantly and positively associated with the corrected overall GAD-7 score (Cronbach's alpha = 0.928, p < 0.0001). The cut-off point for the GAD-7 in ROC curve analysis was 7. The patients with GAD were more likely to be female and single.

CONCLUSION

The traditional Chinese version of the GAD-7 is a reliable and valid self-report questionnaire for detecting GAD in Taiwanese PWE.

Negative life stress, sleep disturbance, and depressive symptoms: The moderating role of anterior insula activity in response to sleep-related stimuli

BACKGROUND

This study investigated the effects of anterior insula (AI) activation on the association between stress and sleep disturbance as a neurobiological basis of the trait-like degree of sleep reactivity to stress. Additionally, it examined the effects of AI activity on the association between sleep disturbance and depression.

METHODS

The participants were 48 adults. To assess AI activation in response to sleep-related stimuli (SS) compared to neutral stimuli (NS), we extracted mean AI parameter estimates for the SS-NS contrast. We examined whether the interaction between life stress and AI activation would predict sleep disturbance and whether the interaction between sleep disturbance and AI activation would predict depression.

RESULTS

At higher levels of bilateral AI activation in response to SS, higher levels of stress were associated with greater sleep disturbance (left AI x stress: b = 1.07, SE = 0.44, p < 0.05; right AI x stress: b = 1.05, SE = 0.48, p < 0.05). In addition, at higher levels of right AI activation, higher levels of sleep disturbance were associated with more severe depressive symptoms (right AI x sleep disturbance: b = 2.55, SE = 1.10, p < 0.05).

LIMITATION

This study assessed sleep quality and depressive symptoms based on self-reported questionnaires.

CONCLUSION

This study revealed moderating effects of AI activation on the association between negative life stress and sleep disturbance. Additionally, AI activation strengthened the association between sleep disturbance and depression. AI activation may reflect a crucial etiological diathesis for insomnia and stress-related disorders.

Cardiac Autonomic Dysfunction Is Associated with Severity of REM Sleep without Atonia in Isolated REM Sleep Behavior Disorder

123I-metaiodobenzylguanidine (MIBG) cardiac scintigraphy was performed to assess cardiac autonomic dysfunction and demonstrate its correlation with clinical and polysomnographic characteristics in patients with isolated rapid eye movement (REM) sleep behavior disorder. All subjects including 39 patients with isolated REM sleep behavior disorder and 17 healthy controls underwent MIBG cardiac scintigraphy for cardiac autonomic dysfunction assessment. The isolated REM sleep behavior disorder was confirmed by in-lab overnight polysomnography. A receiver operating curve was constructed to determine the cut-off value of the early and delayed heart-to-mediastinum ratio in patients with isolated REM sleep behavior disorder. Based on each cut-off value, a comparison analysis of REM sleep without atonia was performed by dividing isolated REM sleep behavior disorder patients into two groups. MIBG uptake below the cut-off value was associated with higher REM sleep without atonia. The lower heart-to-mediastinum ratio had significantly higher REM sleep without atonia (%), both with cut-off values of early (11.0 ± 5.6 vs. 29.3 ± 23.2%, p = 0.018) and delayed heart-to-mediastinum ratio (9.1 ± 4.3 vs. 30.0 ± 22.9%, p = 0.011). These findings indicate that reduced MIBG uptake is associated with higher REM sleep without atonia in isolated REM sleep behavior disorder.

Parental Stress and Mental Health Symptoms in the NICU: Recognition and Interventions

Parental experiences in the NICU are often characterized by psychological stress and anxiety following the birth of a critically ill or premature infant. Such stress can have a negative impact on parents and their vulnerable infants during NICU hospitalization as well as after discharge. These infants are also at increased risk for adverse developmental, cognitive, academic, and mental health outcomes. Identifying parents at risk for psychological distress is important and feasible with the use of well-validated screening instruments. Screening for psychological distress is essential for identifying families in need of referral for psychological support and resources. Numerous interventions have been implemented in the NICU to support parents. These include staff-based support such as wellness rounds and education in developmental care as well as parental-based support that includes cognitive behavioral therapy and home visitation programs. Comprehensive interventions should use a multidisciplinary approach that involves not only NICU staff but also key stakeholders such as social workers, spiritual/religious representatives, specialists in developmental care, and psychiatrists/psychologists to help support families and facilitate the transition to the home. Future efforts should include raising awareness of the psychological stresses of NICU parents and encouraging the development of programs to provide parents with psychological support.

Computer Gaming and Physiological Changes in the Brain: An Insight from QEEG Complexity Analysis

To compare the pattern of brain waves in video game addicts and normal individuals, a case-control study was carried out on both. Thirty participants were recruited from 14 to 20 years old males from two gaming centers. Twenty healthy participants were gathered from different schools in Tehran using the available sampling method. The QEEG data collection was performed in three states: closed-eye and open-eye states, and during a working memory task. As expected, the power ratios did not show a significant difference between the two groups. Regarding our interest in the complexity of signals, we used the Higuchi algorithm as the feature extractor to provide the input materials for the multilayer perceptron classifier. The results showed that the model had at least a 95% precision rate in classifying the addicts and healthy controls in all three types of tasks. Moreover, significant differences in the Higuchi Fractal Dimension of a few EEG channels have been observed. This study confirms the importance of brain wave complexity in QEEG data analysis and assesses the correlation between EEG-complexity and gaming disorder. Moreover, feature extraction by Higuchi algorithm can render support vector machine classification of the brain waves of addicts and healthy controls more accurate.

Transdiagnostic Versus Construct-Specific Cognitive Behavioural Therapy for Emotional Disorders in Patients with High Anxiety Sensitivity: A Double-Blind Randomised Clinical Trial

Anxiety sensitivity (AS) is a common vulnerability in emotional disorders. Due to the pathological role of AS, individuals with high AS are faced with emotional problems. Thus, cognitive behavioural interventions try to reduce these problems by targeting AS. The present study aimed to compare the efficacy of transdiagnostic cognitive behavioural therapy (T-CBT) and construct-specific CBT (CS-CBT) on AS, anxiety, depression, and positive and negative affect in these patients. To this end, 40 patients with high AS were randomly assigned to one of the three groups of T-CBT, CS-CBT, and wait list. Participants were assessed using the Anxiety and Related Disorders Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Anxiety Sensitivity Index-3, Beck Anxiety Inventory, Beck Depression Inventory-II, and Positive and Negative Affect Schedule at baseline, post-treatment, 3-month follow-up, and 6-month follow-up. The findings showed that T-CBT and CS-CBT have a significant effect on AS, anxiety, and negative affect; however, contrary to T-CBT, CS-CBT is not effective for reducing depression and positive affect. T-CBT had a more promising efficacy than CS-CBT in all treatment outcomes. The results show better and more stable efficacy of T-CBT among patients with high AS. It is essential to consider AS as a target for cognitive behavioural intervention for the spectrum of emotional disorders.

A Brief Online and Offline (Paper-and-Pencil) Screening Tool for Generalized Anxiety Disorder: The Final Phase in the Development and Validation of the Mental Health Screening Tool for Anxiety Disorders (MHS: A)

Generalized anxiety disorder (GAD) can cause significant socioeconomic burden and daily life dysfunction; hence, therapeutic intervention through early detection is important. This study was the final stage of a 3-year anxiety screening tool development project that evaluated the psychometric properties and diagnostic screening utility of the Mental Health Screening Tool for Anxiety Disorders (MHS: A), which measures GAD. A total of 527 Koreans completed online and offline (i.e., paper-and pencil) versions of the MHS: A, Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 (GAD-7), and Penn State Worry Questionnaire (PSWQ). The participants had an average age of 38.6 years and included 340 (64.5%) females. Participants were also administered the Mini-International Neuropsychiatric Interview (MINI). Internal consistency, convergent/criterion validity, item characteristics, and test information were assessed based on the item response theory (IRT), and a factor analysis and cut-off score analyses were conducted. The MHS: A had good internal consistency and good convergent validity with other anxiety scales. The two versions (online/offline) of the MHS: A were nearly identical (r = 0.908). It had a one-factor structure and showed better diagnostic accuracy (online/offline: sensitivity = 0.98/0.90, specificity = 0.80/0.83) for GAD detection than the GAD-7 and BAI. The IRT analysis indicated that the MHS: A was most informative as a screening tool for GAD. The MHS: A can serve as a clinically useful screening tool for GAD in Korea. Furthermore, it can be administered both online and offline and can be flexibly used as a brief mental health screener, especially with the current rise in telehealth.

The ultra brief checklist for suicidality

BACKGROUND

Accurately identifying patients at an elevated risk of suicide in minimal time is an important mental health issue. Therefore, we developed the Ultra Brief Checklist for Suicidality (UBCS) and reported its psychometric properties.

METHODS

We studied 544 participants who had completed the UBCS, other self-report measures, and structured clinical interviews by trained interviewers. We explored the psychometric properties of the UBCS's paper-based and online versions by identifying optimal cutoff points, sensitivity, specificity, etc. of all participants.

RESULTS

The mean score of the UBCS (paper-pencil version) in the no-suicide-risk group was 0.23 (SD = 0.73), while in the Risk-Positive (RP) and the High-Risk (HR) groups it was 3.54 (SD = 3.22) and 6.31 (SD = 3.97), respectively. Optimal cutoff points for the RP and HR groups were 1 (AUC = 0.914) and 3 (AUC = 0.928), respectively.

LIMITATIONS

The current findings apply only to adults, not to children or adolescents. The original MINI was used as the assessment instrument's reference standard rather than MINI 7.0.2 of DSM-5. Predictive validity was not addressed as this was not a longitudinal cohort study.

CONCLUSIONS

The UBCS was rigorously tested and validated. More than half the participants completed the UBCS within a minute. It possesses adequate psychometric properties and can be easily administered with minimal clinician time and effort, via paper or Internet. We believe it can contribute to suicide risk identification and timely interventions.

The Centrality of Depression and Anxiety Symptoms in Major Depressive Disorder Determined Using a Network Analysis

BACKGROUND

Comorbid anxiety symptoms are highly prevalent and closely linked with poorer treatment outcomes, chronicity, and hospitalization in major depressive disorder (MDD). Our study aimed to estimate the network of depression and anxiety symptoms that was developed based on a sample of MDD patients.

METHODS

We constructed a network of the 21 Beck Depression Inventory (BDI) symptoms and 21 Beck Anxiety Inventory (BAI) symptoms in 223 patients with MDD who were beginning psychiatric treatment. In addition, each of the depression and anxiety symptoms was considered to be an ordered categorical variable ranging in value from 0 to 3.

RESULTS

The three depression symptoms including loss of energy, loss of interest, and worthlessness and the seven anxiety symptoms including faintness or lightheadedness, feeling of choking, feeling scared, fear of the worst happening, nervousness, inability to relax, and feeling shaky were identified as the ten most central nodes within a network of depression and anxiety symptoms. The inter-connection between irritability and nervousness was a strong trans-diagnostic edge within the network of depression and anxiety symptoms.

LIMITATIONS

Because our study was designed in a cross-sectional manner, the networks were estimated undirectionally.

CONCLUSIONS

Our findings show that depression symptoms are not more central than anxiety symptoms within an estimated network structure of symptoms in patients with MDD. Moreover, the inter-connection between irritability and nervousness may suggests a probable trans-diagnostic association in MDD symptomatology.

Evaluation of depression, anxiety and quality of life in patients with non-obstructive azoospermia

OBJECTIVE

The aim of this study was to determine the levels of depression, anxiety and quality of life in non-obstructive azoospermia (NOA) patients who attended our clinic.

MATERIALS AND METHODS

A total of 40 male patients were included in the study troubled with non-obstructive azoospermia. An etiological classification was made according to the hormone levels of the patients. The semen specimen was obtained by masturbation from the patients. Three questionnaires, the Beck Depression Inventory, the Beck Anxiety Inventory, and the Short Form of the World Health Organization Quality of Life Questionnaire, were utilized in the study.

RESULTS

The mean age of the patients in the study was 32.75±5.22 years. The patients were classified as follows: 26 (65%) patients were idiopathic, 11 (27.5%) patients were hyper-hypo and 3 (7.5%) patients could not be reached. In this cohort, 62.5% of patients had minimal depression, 27.5% of patients had mild depression and 10% of patients had moderate depression. In addition, 97.5% of patients had minimal anxiety and 2.5% of the patients had mild anxiety. Quality of life scores of the patients were 58.75% for general health status, 70.98% for physical health status, 72.92% for psychological status, 65% for social relations and 66.25% for environmental status.

CONCLUSION

NOA particularly affects men in terms of biological, psychological and social aspects. In order to evaluate the quality of life and psychiatric conditions patients with azoospermia, various questionnaires may be applied before infertility treatment. Thus, patients who need psychiatric support can be identified.

Depressive Symptom Network Associated With Comorbid Anxiety in Late-Life Depression

Background: Depression and anxiety are the most common comorbid psychiatric disorders in the elderly. Psychiatrists have been reporting worsened depression symptoms and prognosis by comorbid anxiety symptoms. However, it is still unclear how anxiety affects the course of depression in the elderly. The aims of this study are (1) to identify the symptom network in late-life depression (LLD), and (2) to examine the role of anxiety in LLD with a network perspective. Methods: The study analyzed 776 community-based participants who were clinically diagnosed with depression and enrolled in Suwon Geriatric Mental Health Center. Network analysis was used to investigate the relationships between the symptoms of the Montgomery-Åsberg Depression Rating Scale (MADRS). The depression sample was divided into groups of low and high anxiety according to the Beck Anxiety Index. Propensity score matching (PSM) was used to minimize the effects of depression severity on the network. Network comparison test (NCT) were carried out to compare the global connectivity, global strength, and specific edge strength between the two subgroups. Results: Reported sadness, pessimistic thinking, and suicidal ideation are the core symptoms of LLD in terms of node strength. The MADRS sum score [mean (SD) 28.10 (9.19) vs 20.08 (7.11); P < .01] was much higher in the high anxiety group. The NCT before PSM showed the high anxiety group had significantly higher global strength (P < .01). However, the NCT after PSM did not reveal any statistical significance both in global structure (P = .46) and global strength (P = .26). A comparison between centrality indices showed a higher node strength of vegetative symptoms in the high anxiety group and this also remained after PSM. Conclusion: Based on the statistical analysis, anxiety worsens the severity of depression in the elderly. However, NCT after PSM revealed comorbid anxiety does not change the global structure and strength of the depression symptom network. Therefore, anxiety may affect LLD in a way of worsening the severity, rather than changing psychopathology. Additionally, the study revealed the centrality of vegetative symptoms was low in LLD but increased substantially in patients with comorbid anxiety.
