Depression and somatization: a review. Part I

Fatigue and somatization in shift-workers: Effects of depression and sleep

OBJECTIVE

We investigated the differences in fatigue and somatization between shift and non-shift workers and explored the effects of sleep and depression on fatigue and somatization in shift workers.

METHODS

In total, 4543 shift workers and 2089 non-shift workers completed self-reported questionnaires. The Center for Epidemiologic Studies Depression Scale (CESD), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and Somatization subscale of the Symptom Checklist 90-item version (SCL-SOM) were used to measure depression, sleep quality, fatigue, and somatization, respectively. Fatigue and somatization were compared between shift and non-shift workers after controlling for different sets of covariates.

RESULTS

Compared to non-shift workers, shift workers reported higher FSS (mean difference: 2.19 ± 0.30, p < 0.01) and SCL-SOM (mean difference: 1.77 ± 0.21, p < 0.01) scores after controlling for age, gender, presence of medical illness, occupational category, monthly income, length of service, and weekly working hours. The between-group difference in FSS score was no longer significant after additionally controlling for CES-D (p = 0.15) or PSQI (p = 0.18). The between-group difference in SCL-SOM score showed only non-significant trends after additionally controlling for CES-D (p = 0.09) or PSQI (p = 0.07). The group difference in SCL-SOM scores disappeared after controlling for both CES-D and PSQI scores (p = 0.99).

CONCLUSIONS

Shift workers had higher fatigue and somatization levels than non-shift workers and the group difference was associated with disturbed sleep and depressed mood in shift workers.

Neurological update: the palliative care landscape for atypical parkinsonian syndromes

Atypical parkinsonian syndromes are neurodegenerative conditions, characterised by rapid disease progression and shorter life expectancy compared to idiopathic Parkinson's disease. These conditions inflict substantial physical and psychosocial burden on patients and their families; hence, there is a clear rationale for a palliative care approach from diagnosis. An interdisciplinary care model has been shown to improve symptom burden, quality of life and engagement with advance care planning, in a heterogeneous group of neurodegenerative conditions. In this update, we summarise how the landscape for treating these patients has changed and the questions that still need to be resolved.

The Relationship between the Frequency of Breakfast Consumption, Conversation with Parents, and Somatic Symptoms in Children: A Three-Wave Latent Growth Model

Breakfast consumption is essential for children to generate energy for the day. Parents play an important role in children's breakfast habits and spending time with parents during breakfast greatly influences children's emotional development. Therefore, this study investigated the relationship between the frequency of children's breakfast consumption, time spent in conversation with parents, and children's somatic symptoms. Data were obtained from the Korea Children and Youth Panel Survey 2018 and were initially collected from fourth-grade elementary school students and followed up for three years. SPSS 21.0 and AMOS 21.0 software were used for data analysis. Multivariate latent growth modeling was applied to analyze the effect of the breakfast consumption frequency on children's somatic symptoms and the mediating effect of parent-child conversation time on this relationship. Consequently, as children's frequency of breakfast consumption increased, their somatic symptoms decreased. Furthermore, parent-child conversation time mediated the relationship between these two variables. Therefore, students, parents, and teachers should be educated about the importance of having breakfast and communicating with parents for students' emotional health.

Mental Health and Quality of Life for Disaster Service Workers in a Province under COVID-19

Objective: Healthcare workers and disaster service workers have been reported to be vulnerable to mental health problems during outbreaks of infectious diseases such as the COVID-19 pandemic. This study aimed to investigate the psychosocial characteristics of disaster service workers in charge of COVID-19-related work and also identify the factors affecting their quality of life. Methods: From June 2020 to June 2021, a survey was conducted of 526 disaster service workers in charge of COVID-19-related work. This included those working in public health care centers (PHC), 119 rescue and emergency medical services (119 REMS), public servants of city hall (PS), and police officers. The Korean version of the Fear of COVID-19 Scale, Patient Health Questionnaire-15, Hospital Anxiety and Depression Scale, Insomnia Severity Index, Connor−Davidson Resilience Scale, and World Health Organization quality of life assessment instrument brief form were used. A one-way ANOVA was conducted, and a stepwise regression analysis was carried out to determine the factors affecting quality of life. Results: Regarding quality of life, 119 REMS (180.64 ± 26.20) scored significantly higher than PHC (165.76 ± 23.73) and PS (163.90 ± 23.60), while police officers (176.87 ± 23.17) scored significantly higher than PS (163.90 ± 23.60) (F = 12.373, p < 0.001). Resilience (β = 0.897, p < 0.01) was the most significant explanatory variable, and together with insomnia (β = 0.154, p < 0.01), depression (β = −0.152, p < 0.01), and COVID-19 anxiety (β = −0.057, p < 0.01) accounted for 91.8% of the explanatory variance with regard to quality of life. Discussion: Quality of life was found to be negatively correlated with insomnia, depression, and COVID-19 anxiety while being positively correlated with resilience. Therefore, active interventions are needed to improve the resilience of disaster service workers.

Health-Related Quality of Life, Depressive Symptoms, Anxiety, and Somatization Symptoms in Male and Female Patients with Chronic Tinnitus

Objective: To investigate the joint impact of tinnitus-related distress (TRD), anxiety, depressive symptoms, and other somatization symptoms on health-related quality of life (HRQoL) in female vs. male patients with chronic tinnitus. Method: Three-hundred-and-fifty-two patients with chronic tinnitus completed audiological testing and a psychological assessment battery that comprised—among other measures—German versions of the Tinnitus Questionnaire, Hospital Anxiety and Depression Scale, Somatic Symptom Scale-8, and Health-Related Quality of Life scale. Descriptive analyses examined associations as well as within- and between-gender differences of the measured variables. Gender-specific serial indirect effects analyses aimed to explain the impact of TRD on HRQoL through psychological processes, notably anxiety, depressive symptoms, and somatization symptoms. Results: Both female and male patients yielded lower mental than physical HRQoL and negative associations between the measured psychological variables and HRQoL. Compared to male patients, female patients reported higher levels of tinnitus-related- and wider psychological distress, other somatization symptoms (e.g., headaches), and impairments in mental and physical HRQoL. For each gender, depressive symptoms, anxiety, and somatization symptoms fully mediated the effect of TRD on mental and physical HRQoL. A double-dissociation revealed an interaction of somatization symptoms and depression on the TRD-HRQoL association in women, and of somatization symptoms and anxiety in men. Conclusions: In patients with chronic tinnitus, psychological constructs account for reported impairments in both mental and physical HRQoL. To improve patients’ HRQoL, treatment conceptualizations should consider gender-specific psychological expressions of low mood or anxiety.

Association between dry eye and depressive symptoms in an elderly Chinese population in Taiwan: the Shihpai Eye Study

BACKGROUND

Dry eye may impact quality of life and daily activities and depression is a widespread illness. Many studies showed the two diseases often coexist. However, studies were limited to retrospective chart review. This study aimed to investigate the association between dry eye and depressive symptoms in an older Asian population.

METHODS

The Shihpai Eye Study was a community-based, cross-sectional survey of vision and eye diseases among noninstitutionalized subjects 65 years of age and older in Shihpai, Taipei, Taiwan. Residents fulfilling these criteria were randomly selected to be invited to participate in the study, which included a questionnaire and an eye examination conducted between July 1, 1999 and December 31, 2000.

RESULTS

Of the 2045 subjects recruited, 1361 (66.6%) completed the examination. 8.8% (95% confidence interval (CI): 7.3-10.3%) of the participants were diagnosed to have depressive symptoms. Under multivariate analysis, depressive symptoms were significantly associated with frequent symptoms of dry eye (odds ratio (OR): 1.97, 95% CI: 1.36-2.92; p < 0.001). None of the dry eye signs was associated with depressive symptoms. For participants reporting frequent symptoms, tear-film break-up time ≤ 10 s (OR: 2.06, 95% CI: 1.38-3.05; p < 0.001), Schirmer test score ≤ 5 mm (OR: 2.01, 95% CI: 1.33-3.03; p < 0.001), and meibomian gland disease (OR: 1.99, 95% CI: 1.31-3.01; p = 0.001) were significantly related to depressive symptoms. Fluorescein staining of the cornea was not correlated to depressive symptoms in participants with dry eye symptoms.

CONCLUSIONS

Depressive symptoms are more highly correlated with dry eye symptoms than dry eye signs.

Can Mobile Health Improve Depression Treatment Access and Adherence Among Rural Indian Women? A Qualitative Study

Major Depressive Disorder (MDD) is associated with low rates of treatment and medication non-adherence, more so in low- and middle-income countries (LMICs). Mobile mental health (mHealth) interventions offer promise as a tool to address these problems. However, the feasibility and acceptability of mHealth interventions among rural women in LMICs is unknown. We examined barriers to accessing mental health treatment, reasons for non-adherence, and attitudes towards mHealth solutions among women with MDD in rural south India. Six focus groups were conducted among women with MDD (n = 69) who had been in treatment at a rural community health center. The discussion was transcribed and analyzed using a modified grounded-theory approach. Women perceived limited autonomy within their family structure, and experienced financial and systemic barriers as contributing to poor treatment access and non-adherence. Illiteracy, limited personal access to mobile phones, and preference for in-person clinical consultation were identified as barriers to use of mHealth. This is the first qualitative study, to our knowledge, that examines attitude towards mHealth among women with MDD in a rural setting in India. The study identified contextual barriers that will be important to address before implementing mHealth interventions.

Autoimmune Dry Eye without Significant Ocular Surface Co-Morbidities and Mental Health

Dry eye symptoms can negatively affect the psychological, physical, and social functioning, which can potentially impair the health-related quality of life. This review evaluated the association between autoimmune related dry eye in the absence of significant ocular surface co-morbidities and mental health. This review found a significantly higher prevalence of mental health disorders (such as depression and anxiety) in systemic lupus erythematous, rheumatoid arthritis, systemic sclerosis, Behcet’s disease, and primary Sjogren’s syndrome patients when compared to the general population. Moreover, patients with depression and anxiety interpret ocular sensations differently than healthy controls and the perception of dry eye symptoms can be influenced by their mood. Somatization is common in depression, and this could influence the perception of ocular discomfort. Anti-depressants and anxiolytics with their potential side effects on the tear film status may also contribute or aggravate the dry eye symptoms in these patients. Although ophthalmologists manage the dry eye disease, as per standardized algorithms, they should be mindful of different ocular sensation interpretation and coexistent mental health issues in a large number of this patient group and initiate a multidisciplinary management plan in certain cases. While rheumatologists look after their autoimmune condition, it may be worth liaising with GP and/or psychiatrist colleagues in order to address their neuropathic type pain and mental health co-morbidities.

SCAT5 vs. SCAT3 Symptom Reporting Differences and Convergent Validity in Collegiate Athletes

OBJECTIVE

The Sport Concussion Assessment Tool (SCAT), fifth Edition, Symptom Evaluation (S5SE) differs from previous versions by having examinees report trait (i.e. "typical" feelings) as opposed to state (i.e., "how you feel right now") concussion-like symptoms at baseline. This study assessed differences among, and convergent validity of, scores on the S5SE, SCAT3 Symptom Evaluation (S3SE), and the Brief Symptom Inventory (BSI-18).

METHODS

A total of 113 University of Florida varsity athletes completed symptom questionnaires on the same day in a counterbalanced administration. The final sample consisted of 94 participants (mean age ± SD = 18.4 ± 0.8 years, 57% male, 65% white) from 17 sports. We assessed convergent validity using Spearman rank-order correlations. Within-participant differences were analyzed with Wilcoxon Signed-Rank tests. We qualitatively described free-response answers to the S5SE question that asks, "if not feeling 100%, why?".

RESULTS

S5SE total severity score demonstrated adequate convergent validity with both the S3SE (rho = .407, p < .001) and BSI-18 (rho = .432, p < .001). Domain-specific analyses indicated variable convergent validity (rho < 0.4 to rho > 0.6). Severity scores did not differ between the S3SE and S5SE (p = .500), but 24.5% of participants reported S3SE > S5SE and 34.0% S5SE > S3SE. Three themes emerged from qualitative examination of reasons for "not feeling 100%": (1) tiredness/sleep, (2) adjustment difficulties, and (3) academic/athletic stress.

CONCLUSIONS

Adequate convergent validity exists between SCAT5 and SCAT3 symptom severity in collegiate athletes. However, most examinees report different baseline symptom severity when asked to describe their trait (S5SE) versus state symptoms (S3SE). Clinicians should consider using the new SCAT5 Symptom Evaluation as a screening tool for identifying otherwise healthy or "undiagnosed" individuals who would benefit from targeted interventions.

La dépression dans les populations médicales

La prévalence élevée des états dépressifs dans la clientèle du généraliste (environ 10% des consultants) et chez les patients de médecine interne (15 à 25% des hospitalisés) est maintenant bien établie. Ce fait a été longtemps négligé par les praticiens et les psychiatres; même actuellement son importance reste sous-estimée.

La proportion d’états dépressifs non-identifiés par les praticiens varie de 1/3 à 2/3 selon les études. Les dépressions méconnues sont source de surconsommation médicale (consultations répétées, examens paracliniques, hospitalisations pour bilans) et ont une évolution moins favorable, plus chronique, que les dépressions identifiées et correctement traitées. Des cas sévères de dépression échappent souvent au dépistage, ce qui n’est pas sans conséquences graves: on sait en effet que la majorité des gens qui se suicident ont consulté un médecin dans le mois qui a précédé leur décès.

Parmi les facteurs qui rendent compte de la méconnaissance des états dépressifs par les médecins non-spécialistes, les uns tiennent aux patients qui, dans leur dialogue avec le généraliste, utilisent davantage le langage de la somatisation qu’ils ne verbalisent explicitement un vécu dépressif. D’autres tiennent aux praticiens, à leur intérêt prévalent et parlois exclusif pour les problèmes somatiques, à leur souci légitime de ne pas passer à côté du diagnostic d’une affection médicale, à l’idée qu’ils se font de la dépression et des déprimés, à leur propension à considérer toutes les manifestations dysphoriques comme conséquences légitimes de la maladie physique. Il faut aussi compter avec les conditions d’exercice du généraliste, le temps très court de sa consultation où il n’est pas facile de différencier une réelle pathologie dépressive, généralement liée à des troubles anxieux et moins nette que dans les consultations Psychiatriques, de troubles émotionnels mineurs, situationnels et transitoires.

Les instruments habituellement utilisés pour le dépistage et le diagnostic de la dépression (échelles d’autoévaluation, critères de diagnostic type RDC ou critères du DSM III) n’ont pas été validés pour les populations de patients somatiques. Récemment deux nouveaux instruments viennent d’être mis au point pour la détection de la symptomatologie dépressive chez les patients somatiques: I'échelle HAD (Hospital Anxiety and Depression Scale) de Zigmond et Snaith (1983) et le Questionnaire Abrégé d’Auto-Évaluation de la Symptomatologie Dépressive (QD2A) de Pichot et al. (1984). Ces échelles, de passation rapide et bien acceptées par les patients, peuvent servir d’aide au diagnostic pour le praticien dans la perspective d’un meilleur dépistage de la dépression et d’une prise en charge plus efficace des déprimés.

Symptomatology differences of major depression in psychiatric versus general hospitals: A machine learning approach

BACKGROUND

Symptomatology differences of major depressive disorder (MDD) in psychiatric and general hospitals in China leads to possible misdiagnosis. Looking at the symptomatology of first-visit patients with MDD in different mental health services, and identifying predictors of health-seeking behavior using machine learning may help to improve diagnostic accuracy.

METHODS

1500 patients first diagnosed with MDD were recruited from 16 psychiatric hospitals and 16 general hospitals across China. Socio-demographic characteristics, causal attribution, symptoms of depression within and outside Diagnostic and Statistical Manual of Mental Disorders (DSM) framework were collected using a self-made questionnaire. A predictive model of 62 variables was established using Random forest, symptom frequencies of patients in general hospitals and psychiatric hospitals were compared.

RESULTS

The machine learning approach revealed that symptoms were strong predictors of health-seeking behavior among patients with MDD. General hospitals patients had higher frequencies of suicidal ideation (χ²=15.230, p<0.001), psychosis (χ²=14.264, p<0.001), weight change (all p<0.001), hypersomnia (χ²=25.940, p<0.001), and a tendency of denying emotional/cognitive symptoms compared with psychiatric hospitals patients.

LIMITATIONS

Stigma and preference bias were not measured. Severity of current depressive episodes was not assessed. Data of previous episode(s) was not presented.

CONCLUSIONS

Symptom evaluation targeting specific patient population in different hospitals is crucial for diagnostic accuracy. Suicide prevention reliant on collaboration between general hospitals and psychiatric hospitals is required in the future construction of Chinese mental health system.

Predictors of Asylum Seekers' Health Care Utilization in the Early Phase of Resettlement

BACKGROUND

Asylum seekers display high prevalence rates of posttraumatic stress disorder, depression, anxiety, and panic disorder due to pre-, peri-, and post-migration stressors. In contrast to the high mental health burden, health care utilization among asylum seekers in the early phase of resettlement is low. However, the early stages after migration are a particularly vulnerable phase in which psychosocial support measures are needed to prevent mental disorders from becoming chronic.

OBJECTIVE

To identify predictors of asylum seekers' health care utilization in the early stages of resettlement.

METHODS

Using hierarchical logistic regression analysis, the variance explanation of the (1) general utilization of health care services as well as the individual utilization of (2) outpatient psychiatrists, (3) counselling centers, and (4) general practitioners was analyzed in n = 65 asylum seekers. A structured interview on health care utilization took place between three to five months after assessment of possible predictors. We defined the following three groups of predictors a) the sociodemographic variables gender, age, number of children, religion, language proficiency, b) the psychological variables sense of coherence and emotion regulation as well as c) the asylum seekers' psychiatric diagnoses.

RESULTS

Individual sociodemographic factors, such as gender, age, and number of children as well as the emotion regulation strategy of expressive suppression and sense of coherence were shown to be predictive for the utilization of health care services among asylum seekers.

CONCLUSIONS

Low-threshold, culture-sensitive treatment offers for asylum seekers should be established in the early phase after migration. General practitioners should be a central hub for further referrals to disorder-specific treatments.

Characterization and Comparison of Physical and Mental Health Profiles and Department of Veterans Affairs Health Care Utilization Patterns among Operation Iraqi Freedom/Operation Enduring Freedom Women Veterans in Puerto Rico versus the United States

BACKGROUND

Research on the physical and mental health profiles and patterns of health care use among women veterans receiving health care from the Department of Veterans Affairs (VA) on the island of Puerto Rico is lacking.

METHODS

This cross-sectional study examines differences in physical and mental health conditions, and patterns of VA health care use, between women veterans of the Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) era who were using VA facilities in Puerto Rico (n = 897) and those using U.S.-based VA facilities (n = 117,216) from 2002 to 2015.

RESULTS

Results of fully adjusted logistic regression models revealed that OIF/OEF women in Puerto Rico had heightened risk for global pain-related disorders (i.e., any pain) (adjusted odds ratio [AOR], 1.45; 95% confidence interval [CI], 1.22-1.71), back pain (AOR, 1.83; 95% CI, 1.56-2.14), diabetes (AOR, 1.42; 95% CI, 1.03-1.95), hyperlipidemia (AOR, 3.34; 95% CI, 2.80-3.98), major depression (AOR, 1.78; 95% CI, 1.53-2.06), and bipolar depression (AOR, 1.66; 95% CI, 1.34-2.04). They also evidenced greater risk for a host of reproductive health conditions and had higher average annual use of VA health care than their U.S. counterparts.

CONCLUSIONS

OIF/OEF women receiving VA health care in Puerto Rico evidenced a greater burden of physical illness, depression, and heightened use of VA health care services relative to their U.S. counterparts. Providers' increased awareness of the physical and mental health care needs of this population is warranted. Research efforts that help to identify efficient and effective strategies to provide culturally tailored and/or personalized health care for this population could also be useful.

The mediating effect of health anxiety in the relationship between functional somatic symptoms and illness behavior in Chinese inpatients with depression

BACKGROUND

Functional somatic symptoms in depression disorder may cause inappropriate illness behavior hindering the treatment process. Health anxiety may play a role in this relationship, but few studies have examined it. The current study aimed to investigate the role of health anxiety in the relationship between functional somatic symptoms and illness behavior in patients with depression.

METHODS

The present study recruited 323 hospitalized patients with depression to complete the Patient Health Questionnaire-15, Whiteley-Index-7, and Scale for the Assessment of Illness Behavior, then constructed a structural equation model to examine whether health anxiety mediated the relationship between functional somatic symptoms and illness behavior.

RESULTS

The results showed significant correlations between any two of the three variables of interest. More importantly, health anxiety played a partially mediating role (42.86%) in the relationship between functional somatic symptoms and illness behavior. Further analysis suggested that elderly patients reached higher health anxiety than younger patients when their functional somatic symptoms were mild.

CONCLUSIONS

These results highlight that health anxiety may mediate the influence of functional somatic symptoms on illness behavior. The implications of assessing and intervening in health anxiety in patients with depression were discussed.

Dissociative Experiences In Iranian Depressed Patients

In the present study, 229 major depressive disorder (MDD) patients (57.6% female; 42.4% male) were selected by convenience sampling and examined for rate of dissociative experiences. Research tools were Dissociative Experiences Scale (DES) and demographic questionnaire. Group difference examinations were performed for gender, settlement region (place of residence), and chief complaints using standard t-test, analysis of variance, and Chi-square tests as appropriate. Ordinal regression was implemented for model building. The average age of the sample was 36.78 ± 10.73. Of which, 150 (65.5%) lived in the urban and 79 (34.5%) in the rural areas. The chief complaint of the 146 patients (63.8%) was psychiatric symptoms specific to MDD, and the remaining 83 patients (36.2%) had physical symptoms. The average DES score was 10.59 ± 13.59; and a significant mean DES score differences (P < 0.01) between patients' referred to physician for physical versus psychological complaints (physical: 23.61 ± 14.39; psychological: 3.19 ± 4.5) and geographic settlements (rural: 19.58 ± 15.13; urban: 5.86 ± 9.86) were observed. This study highlights the presence of subtype within MDD patients with significant dissociative tendencies. Given the relationship between trauma history and dissociation, this subgroup could be considered as probable cases with childhood history of abuse, lending to use dissociation as a defense mechanism. Given the evidence for promising results of trauma-focused psychotherapy in treating such patients, paying proper attention to childhood history of depression especially with somatization may minimize pain and suffering of these individuals overtime.

Illness Anxiety Disorder: Psychopathology, Epidemiology, Clinical Characteristics, and Treatment

Illness anxiety disorder is a primary disorder of anxiety about having or developing a serious illness. The core feature is the cycle of worry and reassurance seeking regarding health, as opposed to a focus on relief of distress caused by somatic symptoms (as in Somatic Symptom Disorder). Clinically significant health anxiety is common, with estimates ranging up to 13% in the general adult population. There are evidence-based treatments, including psychopharmacology and cognitive behavioral therapy, that can significantly alleviate symptoms. An understanding of the core psychopathology and clinical features of illness anxiety disorder is essential to fostering a working alliance with patients with health anxiety, as is the maintenance of an empathic, curious, and nonjudgmental stance toward their anxiety. Collaboration between medical providers is essential to avoid the pitfalls of excess testing and medical treatment.

Cultural Factors, Depressive and Somatic Symptoms Among Chinese American and European American College Students

This study seeks to fill a gap in the existing empirical literature about the relationship between somatic and depressive symptoms and their associations with cultural factors among Chinese American and European American college students. In particular, the study examined how three culturally relevant psychological constructs, self-construal, loss of face, and emotion regulation, associate with depressive and somatic symptoms among Chinese American and European American college students and if they can explain possible group differences in depressive symptoms. The sample consisted of 204 Chinese American and 315 European American college students who completed an online survey. Based on multiple regression analyses, European American students reported higher levels of somatic symptoms on the Patient Health Questionnaire–15 (PHQ-15) than Chinese Americans. There was no initial group difference in depressive symptoms based on Center for Epidemiologic Studies–Depression Scale (CES-D) scores. Correlations between depressive and somatic symptoms, independent and interdependent self-construal, and cognitive reappraisal and independent self-construal were stronger for European Americans than Chinese Americans. Somatic symptoms, loss of face, and expressive suppression were positively associated with depressive symptoms, whereas independent self-construal and cognitive reappraisal were negatively associated with depressive symptoms for both groups. When controlling for gender and somatic symptoms, being Chinese American and male was significantly and positively associated with depressive symptoms measured with the CES-D. These ethnic and gender differences in depressive symptoms were explained by independent self-construal, loss of face, cognitive reappraisal, and expressive suppression. Clinical implications include the incorporation of specific culturally relevant constructs and avoidance of race-, ethnicity-, and gender-based stereotypes to reduce health disparities in depression treatment.

Antecedents of depression in children and adolescents

Depression in children and adolescents is a growing health problem in the 21^st century. There is growing evidence that depression poses a significant risk in the developmental trajectory of children and adolescents. It is important to identify the antecedents of depression in this vulnerable group of individuals so as to develop specific and effective preventable techniques and strategies. In this brief review, we have tried to highlight the specific antecedents of childhood and adolescence depression on which evidence is available in a structured manner. Antecedents identified in childhood and adolescent depression were categorized into biological factors, temperament, cognitive vulnerability, family factors, sociodemographic factors, academic factors, changing social milieu, school factors, and peer group influence along with the emergence of the recentproblem of excessive social networking use. Biological and psychosocial factors are equally important in the development of depression in this age group. Antecedents of childhood and adolescence depression can be targeted both to prevent and intervene depression in this population.

Risk and Resilience Factors Related to Parental Bereavement Following the Death of a Child with a Life-Limiting Condition

This paper reviews the theoretical and empirical literature on risk and resilience factors impacting on parental bereavement outcomes following the death of a child with a life-limiting condition. Over the past few decades, bereavement research has focussed primarily on a risk-based approach. In light of advances in the literature on resilience, the authors propose a Risk and Resilience Model of Parental Bereavement, thus endeavouring to give more holistic consideration to a range of potential influences on parental bereavement outcomes. The literature will be reviewed with regard to the role of: (i) loss-oriented stressors (e.g., circumstances surrounding the death and multiple losses); (ii) inter-personal factors (e.g., marital factors, social support, and religious practices); (iii) intra-personal factors (e.g., neuroticism, trait optimism, psychological flexibility, attachment style, and gender); and (iv) coping and appraisal, on parental bereavement outcomes. Challenges facing this area of research are discussed, and research and clinical implications considered.

[Suicide risk in somatoform disorders]

BACKGROUND

The somatoform disorders include a group of complex disorders consist of somatic symptoms for which there are no identifiable organic cause or pathogenetic mechanisms. Given the importance of these disorders and the need to clarify the diagnosis of somatoform disorder affecting the suicide risk, we took into consideration the scientific literature to investigate the correlation between the two conditions.

METHODS

We performed a bibliographic search through Medline, Embase, PsycINFO, Scopus, SciELO, ORCID, Google Scholar, DOAJ using the following terms: somatoform, somatization disorder, pain disorder AND psychological factor, suicide, parasuicide, suicidality.

RESULTS

In all studies reported in our review, the suicidal behavior risk is high. But in the majority, the data are relatively unreliable because it takes into account the category nosographic "Neurotic, stress-related and somatoform disorders", too wide to be able to identify the clinical characteristics of patients at risk of only somatoform disorder.

CONCLUSIONS

Several studies conclude that psychiatric comorbidity increases the suicide risk: patients with two or more psychiatric disorders are more likely to commit a suicide attempt; in particular if there is a axis I diagnosis, the risk reduplicate. The somatization disorder seems to have a significant psychiatric comorbidity in particular with anxious and affective disorders spectrum.

The Theoretical Construction of a Classification of Clinical Somatic Symptoms in Psychosomatic Medicine Theory

Objective

This article adopts the perspective of psychosomatic medicine to present and test a theoretical model of the classification of clinical somatic symptoms. The theoretical model consists of four dimensions: emotional somatic symptoms, biological somatic symptoms, imaginative somatic symptoms, and cognitive somatic symptoms.

Method

A clinical somatic symptom classification scale was developed according to the theoretical model. A total of 542 participants completed the clinical somatic symptoms classification scale. The data were analyzed using exploratory and confirmatory factor analyses.

Results

The results confirmed the theoretical model. The analyses found that the proposed theoretical structure of the scale was good, as indicated by factor loadings and fit indices, and that the scale had good reliability and construct validity.

Conclusions

Based on the interpretation of the clinical symptoms of psychosomatic medicine, the treatment of chronic non-infectious diseases includes at least three dimensions: the first is the etiological treatment, the second is the pathophysiological and pathopsychological dimension, and the third is symptomatic treatment. The unified psychosomatic point of view and diverse clinical thinking modes are aimed at identifying different classes of somatic symptoms and important prerequisites for the treatment of these symptoms. We registered the study with the Chinese Clinical Trial Registry and it was approved by the West China Hospital, Sichuan University ethics committee. Trial registration: The registration number is ChiCTR-OCS-14004632 (time: 2014-05-12).

Depression and anxiety in dry eye disease: a systematic review and meta-analysis

AimTo evaluate the association of dry eye disease (DED) with depression and anxiety.Patients and methodsWe conducted a systematic review and meta-analysis of studies that reported the prevalence, incidence and/or severity grading of depression and/or anxiety in DED patients and healthy controls. We searched MEDLINE, EMBASE, PsycINFO, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform for relevant studies.ResultsTwenty-two eligible studies consisted of 2 980 026 patients were analyzed. DED was associated with an increased prevalence of depression (summary odds ratio (OR)=2.92, 95% CI: 2.13-4.01, P<0.00001) and anxiety (OR=2.80, 95% CI: 2.61-3.02, P<0.00001). The depression score (standardized mean difference (SMD)=0.81, 95% CI: 0.48-1.15, P<0.00001) and anxiety score (SMD=0.37, 95% CI: 0.10-0.64, P=0.007) were higher in DED patients than in controls. Subgroup analyses revealed that the prevalence and severity of depression are greatest in primary Sjogren's syndrome patients. No study reported the incidence.ConclusionDepression and anxiety are more prevalent in DED patients than in controls. Among patients with DED, those suffering from primary Sjogren's syndrome have higher prevalence and severity of depression.

A Comparison Of Depressive Symptons In African Americans And Caucasian Americans

The study examined group differences in depressive symptomatology on the Beck Depression Inventory in 278 African Americans and 278 Caucasian Americans seeking psychotherapy. Relative to Caucasian Americans, African Americans reported less pessimism, dissatisfaction, self-blame, and suicidal ideation and more sense of punishment and weight change, but for reasons unrelated to depression. Self-dislike was a stronger manifestation of depression in Caucasian Americans, and sleep disturbance, loss of appetite, and loss of libido were stronger manifestations of depression in African Americans. Group differences were not accounted for by gender, marital status, age, or education. The study contributes to the understanding of sociocultural variants of self reported depression by distinguishing different ways in which symptomatology may differ.

Psychometric Comparability of the English-and Spanish-Language Versions of the State-Trait Anxiety Inventory

The psychometric adequacy of the English-and Spanish-language versions of the State-Trait Anxiety Inventory (STAI) was compared across English-speaking Latino American women (n = 17) and men (n = 18) and Spanish-speaking Latino American women (n = 10) and men (n = 14) who were experiencing stressful and potentially anxiety-producing situations associated with physical pain. Subjects were administered the STAI as well as the Minnesota Multiphasic Personality Inventory (MMPI) in their preferred language. Psychometric comparisons of language group and gender revealed nonsignificant differences in (a) mean scores on the STAIscales, (b) internal consistency for the STAI scales, and (c) correlations between the STAI scales and MMPI scales. Item analyses identified several salient screening itemsfor the Spanish-speaking men; several items with low item-remainder correlations were revealedfor the English-and Spanish-speaking women. Overall, results attest to the psychometric strengths of the English-and Spanish-language versions of the STAI.

Language-Specific Response Patterns and Subjective Assessment of Health: A Sociolinguistic Analysis

It is a premise of many secondary statistical analyses of cross-sectional data that language choice acts as an adequate proxy to assess level of acculturation of Hispanic respondents. In this article, conclusions are analyzed that point to a tendency of Mexican Americans to make negative subjective health assessments. A sociolinguistic analysis is proposed, one that examines code switching as a communicative option that is available to the members of a bilingual speech community. From this perspective, cultural change provides an individual with additional linguistic and symbolic categories for expressing distress. It is discussed how a Mexican American's choice to speak Spanish at the time of the interview may not indicate that he orshe is prone to exaggerate somatic complaints or that he or she is less acculturated, but rather that the mother tongue is the language of choice to communicate psychic demoralization and somatic distress in the context of health-related interview schedules.

Narratives of Somatizing and Non somatizing Patients in a Primary Care Setting

Somatizing patients, who comprise approximately 20 percent of the primary care population, often present physicians with recurrent but confusing combinations of symptoms without organic explanations. Illness narratives presented during initial medical encounters with primary care physicians were examined qualitatively to determine if the narrative structure, chronological development of symptoms and temporal frame differed between somatizing and non-somatizing patients. Following a structured interview to identify somatization tendency and co-morbidities of depression and post-traumatic stress disorder, 116 patients' encounters with primary care physicians were video-recorded and transcribed. Somatizers demonstrated a narrative structure that was similar to that of non-somatizing patients, but they used a thematic rather than a chronological development of symptoms and they did not convey a clear time frame. Somatizing patients with a co-morbid psychological condition focused on concrete physical sensations, were unable to provide contextual history or chronological organization, and did not develop a temporal frame. The narratives of somatizing and non-somatizing patients differed sufficiently to warrant further research for use as a clinical aid in the diagnosis of somatization.

Relationship Between Palpitation and Mental Health

Background:

‘Palpitation’ is one of the most common complaints in patients referring to cardiologists. In modern medicine era, these patients suffer from much distress and some cases are known to be difficult to treat. Although the clinician’s first duty is obviously to search for an organic basis for this symptom, the diagnostic evaluation is frequently unrevealing. However, clinical experience suggests that psychiatric causes are relatively common.

Objectives:

This research aimed to screen for mental disorders in patients complaining of palpitation and healthy persons in order to perform a preliminary comparison between them.

Patients and Methods:

This is a case-control study to screen mental disorders. The target population consisted of adult volunteers with benign palpitation and their matched healthy persons. They were referred during a 10-month-period to the cardiology outpatient’s clinic of Mostafa Khomeini hospital in Tehran, Iran. Sampling was accidental and eventually 110 participants comprised the sample size. The measuring tool was GHQ-28 (28-item general health questionnaire) and the main variable was the questionnaire score obtained from the Likert scoring method.

Results:

Comparing two groups showed that the number of participants with the scores more than cut-off point in palpitation group was significantly more than healthy person group (85.4% vs. 43.6% with P < 0.001). Also the total score of GHQ-28 and scores of its subscale (somatization, anxiety, and social dysfunction) in patients complaining of palpitation were significantly more than those of the healthy participants (34.2 vs. 25.7, 8.9 vs. 6.4, 9.4 vs. 6.4, and 12.3 vs. 10.8, respectively with P < 0.001, P = 0.001, P < 0.001, and P < 0.007, respectively).

Conclusions:

Palpitation is the most common symptom in psychiatric disorders such as anxiety and somatization disorders. According to the results of this study, psychiatric causes have an important role in Iranian patients complaining of palpitations (benign form). Considering this fact may lead to a more effective treatment of benign palpitations.

A Cross-Cultural Understanding of Depression Among Abused Women

Little research has addressed depression in abused women across cultures. This review examines depression and intimate partner violence (IPV) by comparing and contrasting the IPV definitions, family dynamics, coping, and expressions of depression of women in China, Japan, India, and the United States. Findings reveal that depression is expressed differently across cultures. Somatization is commonly found in Asian countries, but it is not properly assessed by existing Westernized depression assessment tools. In addition, cultural factors were shown to shape abused women's ways of adaptive coping. Cultural awareness and sensitivity are fundamental for successful assessment and intervention for abused women with depression.

Factors Associated with Symptoms of Depression Among Bhutanese Refugees in the United States

Refugees are at risk for psychiatric morbidity, yet little is known about their mental health conditions. We identified factors associated with depression symptoms among Bhutanese refugees in the US. We randomly selected adult Bhutanese refugees (N = 386) to complete a cross-sectional survey concerning demographics, mental health symptoms, and associated risk factors. The case definition for depression symptoms was ≥1.75 mean depression score on the Hopkins Symptom Checklist-25. More women (26%) than men (16%) reported depression symptoms (p = 0.0097). Higher odds of depression symptoms were associated with being a family provider, self-reported poor health, and inability to read and write Nepali (OR 4.6, 39.7 and 4.3, respectively) among men; and self-reported poor health and inability to read and write Nepali (OR 7.6, and 2.6 respectively) among women. US-settled Bhutanese refugees are at risk for depression. Providers should be aware of these concerns. Culturally appropriate mental health services should be made more accessible at a local level.

The Relationship of Hypochondriasis to Anxiety, Depressive, and Somatoform Disorders

BACKGROUND

Though the phenotype of anxiety about medical illness has long been recognized, there continues to be debate as to whether it is a distinct psychiatric disorder and, if so, to which diagnostic category it belongs.

OBJECTIVE

Our objective was to investigate the pattern of psychiatric comorbidity in hypochondriasis (HC) and to assess the relationship of health anxiety to anxiety, depressive, and somatoform disorders.

METHODS

Data were collected as part of a clinical trial on treatment methods for HC. In all, 194 participants meeting criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) HC were assessed by sociodemographic variables, results of structured diagnostic interviews, and validated instruments for assessing various symptom dimensions of psychopathology.

RESULTS

Most of the individuals with HC had comorbid psychiatric illness; the mean number of comorbid diagnoses was 1.4, and 35.1% had HC as their only diagnosis. Participants were more likely to have only comorbid anxiety disorders than only comorbid depressive or somatoform disorders. Multiple regression analysis of continuous measures of symptoms revealed the strongest correlation of health anxiety with anxiety symptoms, and a weaker correlation with somatoform symptoms; in multiple regression analysis, there was no correlation between health anxiety and depressive symptoms.

CONCLUSION

Our findings suggest that the entity of health anxiety (HC in DSM-IV and illness anxiety disorder in DSM-5) is a clinical syndrome distinct from other psychiatric disorders. Analysis of comorbidity patterns and continuous measures of symptoms suggest that its appropriate classification is with anxiety rather than somatoform or mood disorders.

Effect of Alexithymia and Emotional Repression on Postsurgical Pain in Women With Breast Cancer: A Prospective Longitudinal 12-Month Study

Alexithymia, the inability to identify and express emotions, and emotional repression, a defensive mechanism used to avoid unpleasant emotional experience, have been associated with chronic pain and medical illness including breast cancer, but whether these constructs might predict pain after breast cancer surgery has not been assessed. The present study was conducted to assess the predictive value of alexithymia and emotional repression in postoperative pain. Anxiety, depression, catastrophizing, and psychological adjustment were also assessed. Data were collected before surgery, and then at 2 days and 2, 3, 6, and 12 months after surgery. We included 100 pain-free women, 96% of whom were followed for up to 12 months. Separate multivariate analyses identified anxiety as a significant predictor of postsurgical pain at 3 months, alexithymia at 3, 6, and 12 months, and body image and catastrophizing predicted acute or subacute pain at 2 months. In contrast, emotional repression was not predictive of pain. The generalized estimating equation approach was used and identified alexithymia as the only significant predictor of pain during the 12-month period after surgery. Alexithymia, but not emotional repression, predicted the development of persistent pain after breast surgery independently of anxiety and depression. Thus, alexithymia might be involved in mechanisms of pain chronicity.

PERSPECTIVE

This prospective study, conducted in women with breast cancer surgery, showed that alexithymia but not emotional repression predicted postsurgical pain. These results highlight the role of dysfunction in emotional processing in the development of postsurgical pain.

Improving mental and physical health outcomes in general healthcare settings: a Gedenkschrift in honor of Wayne Katon, MD (1950-2015)

This special article pays tribute to Wayne Katon, MD (1950-2015) with a Gedenkschrift, or review, of his prolific academic career. Abstracts of all of Dr. Katon's Medline citations were reviewed to develop a narrative of his seminal epidemiological and interventional research findings. Specifically, we describe: (a) how Dr. Katon's clinical work and observational epidemiology and health services research informed and guided interventional studies; (b) the evolution of multidisciplinary interventional trials from primary care-based psychiatric consultation to primary care-based collaborative care for depression to multicondition collaborative care; and (c) how Dr. Katon's research has informed the work of other leading researchers in the field of psychosomatic medicine and helped develop a new generation of researchers at the interface of psychiatry and primary care. For more than three decades, Dr. Katon led a multidisciplinary research team that conducted seminal epidemiological studies and randomized trials and that influenced the thinking and research in the field of psychiatry in a number of areas: (a) the importance and impact of mental disorders presenting in primary care settings and (b) the organization of effective multidisciplinary care for primary care patients with common mental disorders and comorbid medical conditions. Dr. Katon's work revolutionized the care of psychiatric illnesses in primary care and other medical care settings to the benefit of countless patients worldwide.

Caregiver burden in frontotemporal degeneration and corticobasal syndrome

BACKGROUND AND AIMS

Caregiver stress is often a serious problem when caring for a patient with frontal lobe dysfunction.

METHODS

A total of 102 caregivers of both patients with frontotemporal degeneration and corticobasal syndrome completed the Frontal Systems Behavior Scale (FrSBe) and the Zarit Burden Interview (ZBI). To analyze the association between apathy or disinhibition (or both) and caregiver burden, the effects of the total FrSBe and the apathy and disinhibition subscales of the FrSBE on the total ZBI score were assessed with logistic regressions and t tests.

RESULTS

Total FrSBE score and the apathy FrSBE subscore predicted caregiver burden. Apathy occurred without disinhibition, and the two occurred together, but disinhibition without apathy was very rare.

CONCLUSIONS

Disinhibition without apathy occurred very rarely. Apathy was more associated with caregiver burden than disinhibition.

Cultural adaptation in measuring common client characteristics with an urban Mainland Chinese sample

OBJECTIVES

This study aimed to develop a culturally adapted version of the Systematic Treatment Selection-Innerlife (STS) in China.

METHODS

A total of 300 nonclinical participants collected from Mainland China and 240 nonclinical US participants were drawn from archival data. A Chinese version of the STS was developed, using translation and back-translation procedures. After confirmatory factor analysis (CFA) of the original STS sub scales failed on both samples, exploratory factor analysis (EFA) was then used to access whether a simple structure would emerge on these STS treatment items. Parallel analysis and minimum average partial were used to determine the number of factor to retain.

RESULTS

Three cross-cultural factors were found in this study, Internalized Distress, Externalized Distress and interpersonal relations.

CONCLUSIONS

This supported that regardless of whether one is in presumably different cultural contexts of the USA or China, psychological distress is expressed in a few basic channels of internalized distress, externalized distress, and interpersonal relations, from which different manifestations in different culture were also discussed.

Anxiety and depression predicted by medically unexplained symptoms in Pakistani children: a case-control study

OBJECTIVE

To explore association between medically unexplained symptoms in children in Pakistan with emotional difficulties and functional impairments.

METHODS

We conducted a matched three-group case-control study of 186 children aged 8-16 years in Lahore, Pakistan. Cases were 62 children with chronic somatic symptoms for which no organic cause was identified after investigations. Two control groups of 62 children with chronic medical paediatric conditions, and 62 healthy children were identified. Cases and controls were matched for gender, age, and school class. Somatisation was measured with the Children's Somatisation Inventory (CSI-24) while anxiety and depression were measured with the Spencer Children's Anxiety Scale and the Short Mood and Feelings Questionnaire respectively. All questionnaires were translated into Urdu.

RESULTS

Mean age was 11.7 years (SD=2.1). Cases scored significantly higher on somatisation (CSI-24), anxiety and depression than both control groups. Paediatric controls scored significantly higher than healthy controls on all three measures. Two hierarchical linear regression models were used to explore if somatisation predicted depression and anxiety while controlling for several confounders. Somatisation (higher CSI-24 scores) independently and significantly predicted higher anxiety (β=.37, p=.0001) and depression (β=.41, p=.0001) scores.

CONCLUSION

This is the first study to show an association between medically unexplained symptoms and anxiety and depression in Pakistani children. This highlights the importance of screening for emotional difficulties in children presenting with unexplained somatic symptoms in this region.

Maternal age and number of children are risk factors for depressive disorders in non-perinatal women of reproductive age

OBJECTIVE

It remains unclear whether or not the vulnerability of depression in women of reproductive age is related with pregnancy or perinatal period. The aim of the study was to determine the prevalence of depressive disorders and related factors in a large sample of non-perinatal women of reproductive age.

METHOD

This study involved 589 women of reproductive age. At baseline, sociodemographic data and premenstrual assessment forms were completed, and screening tests for the assessment of the severity of depressive symptoms were administered to all of the participants. Participants who had over scale scores of the cut-off point in the screening instruments were assessed with module A of the Structured Clinical Interview for DSM Disorders (SCID-I) to determine DSM IV Axis I disorders.

RESULTS

The prevalence of depressive disorders was 32.8%. Depressive disorders had high rates in women who were married at younger ages and who had three or more children. Although the prevalence of depressive disorders was 32.8%, only 10.4% of the women had follow-up and treatment in a psychiatric outpatient clinic.

CONCLUSION

Low education levels, early maternal age, and having more than three children and higher premenstrual symptom scores were risk factors for depressive disorders in non-perinatal reproductive age.

An overview of the management of persistent musculoskeletal pain

Musculoskeletal pain is a common reason for patients to seek care from healthcare providers. These conditions are predominantly nontraumatic injuries with a broad differential diagnosis and often without a specific diagnosis despite thorough history and examination. The management of these conditions is often discouraging for patients with continued chronic symptoms despite numerous diagnostic workups and treatment options. Effective communication with respect to the patient's goals is the key to a good outcome. The combination of an accurate diagnosis, an informed, motivated patient and a comprehensive review of the potential treatment options is beneficial for long-term success.

Diagnostic classifications in depression and somatization should include biomarkers, such as disorders in the tryptophan catabolite (TRYCAT) pathway

The tryptophan catabolite (TRYCAT) pathway is induced by indoleamine 2,3-dioxygenase (IDO), which upon activation depletes plasma tryptophan (TRP) and increases the synthesis of TRYCATs. Both phenomena are associated with somatization and depression. The aims of this study are to examine whether disorders in the TRYCAT pathway are specific to depression or somatization and whether the diagnoses somatization, depression, and comorbid depression+somatization reflect qualitatively distinct clinical and biological categories. Plasma TRP, the kynurenine (KY)/TRP and KY/kynurenic acid (KA) ratios were measured in 36 patients with somatization, 35 depressed and 38 depressed+somatization patients and 22 controls. Using pattern recognition methods, the diagnosis comorbid depression+somatization could not be validated, while there was an important overlap between depression and somatization, which form one continuum. Cluster analysis detected a) a control cluster; b) a cluster with lower tryptophan, and higher KY/TRP and KY/KA ratios and somatization scores; and c) a cluster with increased depression but lower KY/TRP values. The differences between both patient clusters were quantitative and not qualitative. Within the patient group, cluster analysis has generated a "pathway phenotype", i.e. aberrations in the TRYCAT pathway, which are associated with somatization rather than with depression.

Factor structure of the Center for Epidemiologic Studies Depression Scale in Taiwanese adolescents

BACKGROUND

The original study of Radloff (Appl Psychol Meas. 1977. 1:385-401) on the Center for Epidemiologic Studies Depression Scale (CES-D) indicated a 4-factor model in the adult population. However, the factor structure of the CES-D in Asian adolescents has not been extensively validated. The aim of this study was to examine the factor structure of the Chinese version of the CES-D in a large representative Taiwanese adolescent population.

METHOD

A total of 10 116 adolescents completed the Chinese version of the CES-D. We used confirmatory factor analysis to examine the adequacy of 5 models of the factor structure in adolescents who were divided into 4 groups by sex and age. We also enrolled the variables of suicide tendency, insomnia, and peer relationships into the confirmatory factor analysis to examine the factor structure of the CES-D and examined the correlations between the CES-D factors and these variables.

RESULTS

The results of this study indicated that the four-factor model (depressed affect, somatic symptoms, interpersonal problems, and positive affect) had the highest validity in Taiwanese adolescents. We also found that although the 4 factors of the CES-D were correlated with each other, their correlations with suicide tendency, insomnia, and peer relationships were different.

CONCLUSIONS

This study supported the usefulness of the Chinese version of the CES-D as a tool to understand the concept of depression in Taiwanese adolescents.
