Assessment of Somatization and Medically Unexplained Symptoms in Later Life

Measurement Properties of the Patient Health Questionnaire-15 and Somatic Symptom Scale-8: A Systematic Review and Meta-Analysis

Importance

The subjective experience of somatic symptoms is a key concern throughout the health care system. Valid and clinically useful instruments are needed.

Objective

To evaluate the measurement properties of 2 widespread patient-reported outcomes: the Patient Health Questionnaire-15 (PHQ-15) and Somatic Symptom Scale-8 (SSS-8).

Data Sources

Medline, PsycINFO, and Web of Science were last searched February 1, 2024.

Study Selection

English-language studies reporting estimates pertaining to factor analysis, taxometric analysis, internal consistency, construct validity, mean scores in relevant groups, cutoffs, areas under the receiver operating characteristic curves (AUROCs), minimal clinically important difference, test-retest reliability, or sensitivity to change.

Data Extraction and Synthesis

Search hits were reviewed by independent raters. Cronbach α, Pearson r, means, and between-group effect sizes indicative of sensitivity to change were pooled in random-effects meta-analysis. Study quality was assessed using 3 instruments. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 reporting guideline.

Main Outcomes and Measures

Comprehensive overview of evidence pertaining to the measurement properties of the PHQ-15 and SSS-8.

Results

A total of 305 studies with 361 243 participants were included. Most concerned routine care (178 studies) and the general population (27 studies). In factor analyses, both scales reflected a combination of domain-specific factors (cardiopulmonary, fatigue, gastrointestinal, pain) and a general symptom burden factor. The pooled PHQ-15 α was 0.81 (95% CI, 0.80-0.82), but with low item-total correlations for items concerning menstrual problems, fainting spells, and sexual problems (item-total correlations <0.40), and the SSS-8 α was 0.80 (0.77-0.83). Pooled correlations with other measures of somatic symptom burden were 0.71 (95% CI, 0.64-0.78) for the PHQ-15 and 0.82 (95% CI, 0.72-0.92) for the SSS-8. Reported AUROCs for identification of somatoform disorders ranged from 0.63 (95% CI, 0.50-0.76) to 0.79 (95% CI, 0.73-0.85) for the PHQ-15 and from 0.71 (95% CI, 0.66-0.77) to 0.73 (95% CI, 0.69-0.76) for the SSS-8. The minimal clinically important difference on both scales was 3 points. Test-retest reliability could not be pooled and was inconsistent for the PHQ-15 (PHQ-15: r = 0.65-0.93; ICC, 0.87; SSS-8: r = 0.996, ICC = 0.89). The PHQ-15 showed tentative sensitivity to change (g = 0.32; 95% CI, 0.08-0.56), but data for the SSS-8 were lacking.

Conclusions and Relevance

In this systematic review and meta-analysis, findings supported use of the PHQ-15 and SSS-8 for the assessment of symptom burden, but users should be aware of the complex, multifactorial structures of these scales. More evidence is needed concerning longitudinal measurement properties.

Characteristics and economic burden of patients with somatoform disorders in Chinese general hospitals: a multicenter cross-sectional study

BACKGROUND

In China, patients with somatoform disorders (SFD) often seek medical treatment repeatedly in outpatient clinics of general hospitals, which increases unreasonable medical expenses. It is imperative to provide early screening to these patients and specialized treatment to reduce the unnecessary cost. This study aimed to screen patients with SFD in general hospitals using a new Chinese questionnaire and explore the characteristics and economic burden of these patients.

METHODS

Patients (n = 1497) from the outpatient department of neurology, cardiology and gastroenterology of three large general hospitals were included. Participants were screened using a newly developed questionnaire, the Self-screening Questionnaire for Somatic Symptoms (SQSS), to identify the patients with SFD (total SQSS score ≥ 29 points). We compared the demographics and clinical information of patients with and without SFD. Logistic regression was used to explore potential factors related to medical expenses, visits to doctors and sick leave days taken.

RESULTS

The frequency of detection of patients with SFD was 17.03%. There were significant differences in employment, doctor visits, symptom duration, medical expenses, sick leave days, PHQ-15 scores, and PHQ-9 scores between patients with SFD and without SFD. General nonspecific somatic symptoms were frequently present in patients with SFD. Several potential factors were associated with higher medical expenses, repeated doctor visits, and sick leave days taken in the regression analysis.

CONCLUSION

The findings indicate that patients with SFD are common in general hospitals, and their direct and indirect economic burden is higher than that of non-SFD patients, which indicates that more screening effort should be made to this group to early identify their problems. Certain characteristics were identified among patients with SFD and several factors were associated with negative consequences of SFD, all of which might be prevented by developing a preventive intervention program to reduce the economic burden of the patients.

Psychological distress in three Australian communities living with environmental per- and polyfluoroalkyl substances contamination

BACKGROUND

Environmental chemical contamination is a recognised risk factor for psychological distress, but has been seldom studied in the context of per- and polyfluoroalkyl substances (PFAS) contamination. We examined psychological distress in a cross-sectional study of three Australian communities exposed to PFAS from the historical use of aqueous film-forming foam in firefighting activities, and three comparison communities without environmental contamination.

METHODS

Participation was voluntary following recruitment from a PFAS blood-testing program (exposed) or random selection (comparison). Participants provided blood samples and completed a survey on their exposure history, sociodemographic characteristics, and four measures of psychological distress (Kessler-6, Distress Questionnaire-5, Patient Health Questionnaire-15, and Generalised Anxiety Disorder-7). We estimated prevalence ratios (PR) of clinically-significant psychological distress scores, and differences in mean scores: (1) between exposed and comparison communities; (2) per doubling in PFAS serum concentrations in exposed communities; (3) for factors that affect the perceived risk of living in a community exposed to PFAS; and (4) in relation to self-reported health concerns.

RESULTS

We recruited 881 adults in exposed communities and 801 in comparison communities. We observed higher levels of self-reported psychological distress in exposed communities than in comparison communities (e.g., Katherine compared to Alice Springs, Northern Territory: clinically-significant anxiety scores, adjusted PR = 2.82, 95 % CI 1.16-6.89). We found little evidence to suggest that psychological distress was associated with PFAS serum concentrations (e.g., Katherine, PFOS and anxiety, adjusted PR = 0.85, 95 % CI 0.65-1.10). Psychological distress was higher among exposed participants who were occupationally exposed to firefighting foam, used bore water on their properties, or were concerned about their health.

CONCLUSION

Psychological distress was substantially more prevalent in exposed communities than in comparison communities. Our findings suggest that the perception of risks to health, rather than PFAS exposure, contribute to psychological distress in communities with PFAS contamination.

Chronic Pain and Depression are Increased in Outpatient Adults with Somatic Symptoms from Secondary Health Care Services

BACKGROUND

Somatic symptom disorder is described as excessive thoughts, feelings, or behaviors related to physical symptoms. The presence of somatic symptoms has been associated with depression, alexithymia, and the presence of chronic pain. Individuals with somatic symptom disorder are frequent attenders of primary health care services.

AIM

We focused on investigating if the presence of psychological symptoms, alexithymia, or pain could be risk factors for somatic symptoms in a secondary health care service.

METHODS

A cross-sectional and observational study. A total of 136 Mexican individuals who regularly attend a secondary health care service were recruited. The Visual Analogue Scale for Pain Assessment, the Symptom Checklist 90, and the Patient Health Questionnaire-15 were applied.

RESULTS

Of all the participants, 45.2% showed somatic symptoms. We observed that these individuals more frequently presented with complaints of pain (χ² = 18.4, p < .001), as well as more severe (t = -4.6, p < .001), and prolonged (χ² = 4.9, p = 0.02). They also exhibited higher severity in all psychological dimensions assessed (p < .001). Finally, cardiovascular disease (t = 2.52, p = .01), pain intensity (t = 2.94, p = .005), and SCL-90 depression (t = 7.58, p < .001) were associated with somatic symptoms.

CONCLUSIONS

In this study, we observed a high frequency of somatic symptoms in outpatients attending secondary health care services. They may be accompanied by comorbid cardiovascular conditions, higher pain intensity, and other mental health-related symptoms, which may aggravate the general clinical picture presented by the patient seeking health care. The presence and severity of somatization should be taken into consideration in the first and second level health care services for an early mental state evaluation and treatment of these outpatients to have a better clinical assessment and health outcome.

Weathering within war: Somatic health complaints among Vietnamese older adults exposed to bombing and violence as adolescents in the American war

OBJECTIVE

People living in war may experience deteriorating health via weathering (wear and tear) from long-term exposures to psychosocial and environmental stressors. Weathering embodied in somatic health complaints may illuminate the effects of war on health.

METHODS

We investigate whether wartime stress exposures occurring during adolescence and early adulthood affect weathering in late adulthood via linear regression with data from the Vietnamese Health and Aging Study (VHAS). VHAS is a cross-sectional study wherein investigators surveyed 2447 adults aged 60+ in four districts of northern and central Vietnam in 2018. These same individuals ranged in age from seven to 52 in 1965, with most having been in adolescence or early adulthood at the peak of the American war in Vietnam (1965-1975). The sample used for this study (n = 2254) were participants in the first VHAS wave in 2018.

RESULTS

We find older Vietnamese adults exposed to higher-intensity provincial bombing suffer more numerous somatic health complaints (unstandardized β = 0.005, SE = 0.001, p = 0.001). Additionally, greater health complaints emerge among older adults whose most intense bombing exposures were at younger ages of adolescence (< age 15) as compared to those whose peak exposures were in older ages (19-25) (unstandardized β = 0.62 95%, SE = 0.19, p = 0.01).

CONCLUSION

Our findings suggest that age of exposure to armed conflict is a critical determinant of weathering across the life course.

Association of Depressive and Somatic Symptoms with Heart Rate Variability in Patients with Traumatic Brain Injury

Depressive and somatic symptoms are common after traumatic brain injury (TBI). Depression after TBI can relate to worsened cognitive functioning, functional impairment, higher rates of suicide attempts, and larger health care costs. Heart rate variability (HRV) represents the activity of the autonomic nervous system (ANS), which regulates almost all vascular, visceral, and metabolic functions. Several studies show a correlation between HRV, depression, and somatic symptoms in other diseases. However, studies on autonomic dysfunction, depression, and somatic symptoms in TBI patients are lacking. This study investigated the association between reduced ANS function, depression, and somatic symptoms in TBI patients. We retrospectively recruited 136 TBI patients who underwent 24 h ambulatory Holter electrocardiography to measure autonomic dysfunction within 1 month of onset. Patients who used BDI and PHQ-15 to evaluate depressive and somatic symptoms were included. Using Pearson's correlation analysis and multiple linear regression, the association between HRV parameters and BDI and PHQ-15 was determined. The HRV parameters and BDI and PHQ-15 showed statistical significance. In addition, HRV was shown to be a significantly associated factor of BDI and PHQ-15. HRV was associated with depressive and somatic symptom severity in TBI patients. Additionally, autonomic dysfunction may serve as an associated factor of depressive and somatic symptoms in patients with TBI.

Brief Report: Child Sexual Abuse and Somatic Symptoms in Older Adulthood for Men

Somatic symptom disorders are often misdiagnosed or minimized among men, especially in middle and older adulthood. Previous research investigating links between somatic disorders and early trauma, such as childhood sexual abuse (CSA), have mostly been based on small, non-representative, female samples using cross-sectional designs. The current study used data from the Wisconsin Longitudinal Study to assess associations between CSA and somatic symptom severity among men in middle- and late-adulthood (mid-50s to early 70s) with histories of CSA (n = 129) and a matched, non-abused comparison group (n = 2,322). Childhood (e.g., co-occurring adversities and parental education) and demographic background variables (e.g., marital status, self-rated health, and income) were controlled. Growth curve modeling was used to explore trajectories of somatic symptoms over time. Results indicated that the CSA group had higher somatic symptom severity than the non-abused group (γ01 = .10, p < .05); symptoms decreased over time for both groups with no significant differences in the rate of change. Healthcare providers should include CSA in assessments for men. Because contemporary somatic symptoms may represent unresolved early life course trauma, mental health support services should be expanded for this population. Future research should explore gender-appropriate treatment modalities for older men with histories of CSA.

Using the Patient Health Questionnaire to estimate prevalence and gender differences of somatic symptoms and psychological co-morbidity in a secondary inpatient population with abdominal pain

BACKGROUND

Somatic disorders and somatic symptoms are common in primary care populations; however, little is known about the prevalence in surgical populations. Identification of inpatients with high somatic symptom burden and psychological co-morbidity could improve access to effective psychological therapies.

METHODS

Cross-sectional analysis (n = 465) from a prospective longitudinal cohort study of consecutive adult admissions with non-traumatic abdominal pain, at a tertiary hospital in New South Wales, Australia. We estimated somatic symptom prevalence with the Patient Health Questionnaire-15 at three cut-points: moderate (⩾10), severe (⩾15) and 'bothered a lot' on ⩾3 symptoms; and psychological co-morbidity with the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 at standard (⩾10) cut-points. We also examined gender differences for somatic symptoms and psychological co-morbidity.

RESULTS

Prevalence was moderate (52%), female predominance (odds ratio = 1.71; 95% confidence interval = [1.18, 2.48]), severe (20%), no gender difference (1.32; [0.83, 2.10]) and 'bothered a lot' on ⩾3 symptoms (53%), female predominance (2.07; [1.42, 3.03]). Co-morbidity of depressive, anxiety and somatic symptoms ranged from 8.2% to 15.9% with no gender differences.

CONCLUSION

Somatic symptoms were common and psychological triple co-morbidity occurred in one-sixth of a clinical population admitted for abdominal pain. Co-ordinated surgical and psychological clinical intervention and changes in clinical service organisation may be warranted to provide optimal care.

OUP accepted manuscript

Background

Somatic syndromes are present in 30 per cent of primary healthcare populations and are associated with increased health service use and health costs. Less is known about secondary care surgical inpatient populations.

Methods

This was a prospective longitudinal cohort study (n = 465) of consecutive adult admissions with an episode of non-traumatic abdominal pain, to the Acute General Surgical Unit at a tertiary hospital in New South Wales, Australia. Somatic symptom severity (SSS) was dichotomized using the Patient Health Questionnaire (PHQ)-15 with a cut-off point of 10 or higher (medium–high SSS) and compared pre-admission and during admission. Total healthcare utilization and direct costs were stratified by a PHQ-15 score of 10 or higher. Linear regression was used to examine differences in costs, and a multivariable linear regression was used to examine the relationship of PHQ-15 scores of 10 or higher to total costs, reported as mean total costs of care and percentage difference (95 per cent confidence intervals).

Results

Fifty-two per cent (n = 242) of participants had a medium–high SSS with greater pre-admission and admission interval health service costs. Mean total direct costs of care were 25 per cent (95 per cent c.i. 8 to 44 per cent) higher in the PHQ-15 score of 10 or higher group: mean difference €1401.93 (95 per cent c.i. €512.19 to €2273.67). The multivariable model showed a significant association of PHQ-15 scores of 10 or higher (2.1 per cent; 0.2–4.1 per cent greater for each one-point increase in score) with total hospital costs, although the strongest contributions to cost were older age, operative management, and lower socioeconomic level. There was a linear relationship between PHQ scores and total healthcare costs.

Conclusions

Medium to high levels of somatic symptoms are common in surgical inpatients with abdominal pain and are independently associated with greater healthcare utilization.

Does Functional Somatic Symptoms Measurement Differ Across Sex and Age? Differential Item Functioning in Somatic Symptoms Measured With the CIDI

Functional Somatic Symptoms (FSS) are physical symptoms that cannot be attributed to underlying pathology. Their severity is often measured with sum scores on questionnaires; however, this may not adequately reflect FSS severity in subgroups of patients. We aimed to identify the items of the somatization section of the Composite International Diagnostic Interview that best discriminate FSS severity levels, and to assess their functioning in sex and age subgroups. We applied the two-parameter logistic model to 19 items in a population-representative cohort of 962 participants. Subsequently, we examined differential item functioning (DIF). "Localized (muscle) weakness" was the most discriminative item of FSS severity. "Abdominal pain" consistently showed DIF by sex, with males reporting it at higher FSS severity. There was no consistent DIF by age, however, "Joint pain" showed poor discrimination of FSS severity in older adults. These findings could be helpful for the development of better assessment instruments for FSS, which can improve both future research and clinical care.

Psychosomatic symptoms questionnaire (PSQ-39): a psychometric study among general population of Iranian adults

BACKGROUND

Psychosomatic symptoms, characterized by physical-bodily complaints not fully explained by organic reasons, are highly prevalent. The present study aimed to culturally adapt and evaluate the psychometric properties of Psychosomatic Symptoms Questionnaire 39-item version (PSQ-39) among Iranian general adult population.

METHODS

This study included 996 Persian-speaking people, living in Isfahan, Iran. The translation of the PSQ-39 was performed using the forward-backward method. Test-retest reliability was evaluated through Intraclass correlation (ICC) coefficient and internal consistency by using Cronbach's α. Construct validity was investigated by using both exploratory (EFA) and confirmatory (CFA) factor analysis. Short Form Health Survey (SF-36) was used to assess divergent validity. Known-group validity was also assessed.

RESULTS

The Persian version of the PSQ-39 showed excellent test-retest reliability in all domains (ICCs: 0.95-0.99). The computed Cronbach's alpha coefficients for domains of PSQ-39 were in the range good to excellent. The PSQ-39 showed good known-group validity and differentiated patients from the general population (Area under the curve [AUC] of 0.78 (95% CI: 0.73, 0.84). Construct validity evaluated by EFA led to extraction of seven factors (Cardiorespiratory, musculoskeletal, psychological, gastrointestinal, general, body balance and Globus), and the CFA confirmed the adequacy of extracted factors by EFA (CFI = 0.91, TLI = 0.90, PCFI = 0.77, PNFI = 0.71, CMIN = 1413.18 (df = 654), CMIN/DF = 2.16, and RMSEA = 0.06). Significant negative correlations between all domains of PSQ and SF-36 revealed an acceptable divergent Validity.

CONCLUSIONS

The Persian version of the PSQ-39 is a reliable and valid questionnaire with applicability in a broad range of Persian language populations for assessing common psychosomatic symptoms in research as well as in clinical practice.

Translation and validation of the Greek version of the Somatic Symptom Scale-8 (SSS-8) in patients with chronic low back pain

PURPOSE

To translate and validate the Greek version of the Somatic Symptom Scale-8 (SSS-8) in patients with chronic low back pain (CLBP).

MATERIALS AND METHODS

The Greek SSS-8, created through forth and back translation and cultural adaption processes, was handed over to 145 patients recruited using simple random sampling. Test-retest, composite, and internal consistency reliability were assessed. Construct validity was examined by assessing correlations with Patient Health Questionnaire-15 (PHQ-15), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and EuroQoL 5-dimension 5-level (EQ-5D-5L) instruments. Structural validity was assessed using confirmatory factor analysis (CFA). Convergent, discriminant, and known group validity were also evaluated.

RESULTS

The response rate was 95.1% (138 subjects, mean age 43.2 ± 11.7) and the overall Cronbach's alpha was 0.831. Test-retest reliability assessment revealed excellent results (Pearson's r > 0.996; Lin's concordance coefficient > 0.995; intraclass correlation coefficient >0.995, all p < 0.001). Composite reliability scores for the pain, cardiopulmonary, and fatigue domains were 0.712, 0.787, and 0.567, respectively. The correlation analyses indicated good construct validity. CFA revealed excellent fit results and known group validity output indicated a linear increasing trend in the severity of somatic symptom disorders (SSDs), depression, and anxiety with higher PHQ-15, PHQ-9, and GAD-7 scores (Jonckheere-Terpstra test, p value < 0.001).

CONCLUSIONS

The Greek SSS-8 was shown to be a reliable and valid tool for measuring SSDs in patients with CLBP.Implications for RehabilitationAccording to the Global Burden of Diseases Study 2017, LBP was one of the leading causes of disability for both sexes combined since 1990.Strategies to identify SSDs in patients with LBP at an earlier stage are essential both for the provision of an optimal targeted treatment and for minimizing its direct and indirect economic burden.The Greek SSS-8 is a standardized and validated instrument, which its utilization will enhance the physical therapy assessment process in the Greek population.Not only is the SSS-8 an easy-to-use and highly accurate diagnostic tool for detecting SSDs, but also a short alternative to PHQ-15 in settings with limited assessment time.

Symptom Burden Is Associated with Psychological Wellbeing and Mortality in Older Adults

IMPORTANCE

Over half of outpatient visits are due to physical symptoms; yet, the significance of symptoms in relation to older people's wellbeing and prognosis has gained very little research attention.

OBJECTIVES

This study aims to analyze the prognostic value of symptom burden, derived from symptom count and frequency, in an older cohort aged 75 to 95. We also explore the association between symptom burden and psychological wellbeing.

DESIGN

Randomly assigned cohorts of community-dwelling people aged 75-95 filled in the postal questionnaire of the Helsinki Aging Study in 2009.

SETTING

Community-based, postal questionnaires (survey response rate 74%).

PARTICIPANTS

1583 community-dwelling people aged 75-95 in the urban Helsinki area. Main outcomes and measures: The inquired symptoms were dizziness, back pain, joint pain, chest pain or discomfort, shortness of breath, leg pain when walking, loss of appetite, and urinary incontinence. Symptom burden was calculated according to the number of symptoms and their frequency (score range: 0-8). The participants were subdivided into four groups according to their symptom burden. Mortality data was extracted from the Finnish Population Register in 2014. Psychological wellbeing (PWB) was measured using the validated PWB score.

RESULTS

Of 1583 participants, 18% reported no symptoms over the past 2 weeks (Group 0), 31% scored 0.5-1 in the symptom burden score (Group 1), 23% scored 1.5-2 (Group 2), and 28% scored 2.5-8 (Group 3). There was a linear relationship between symptom burden and comorbidities, functional status, falls, and PWB. The groups showed a significant difference in 5-year mortality, even adjusted for age, sex, and comorbidities: Group 1 1.18, 95% CI 0.84-1.66; Group 2 1.63, 95% CI 1.15-2.31, and Group 3 2.08, 95% CI 1.49-2.91 compared to Group 0 (p for linearity <0.001). Conclusion and relevance: Symptom burden is associated with higher mortality and lower PWB independent of comorbidities in community-dwelling people aged 75-95. We conclude that somatic symptoms need to be assessed when examining the general health status of an aging patient. Self-reported symptoms seem to convey information about health that cannot be derived from medical diagnoses only.

Association Between Somatization and Nonmotor Symptoms Severity in People With Parkinson Disease

OBJECTIVE

To assess the frequency of somatization and its association with motor, nonmotor symptoms, and quality of life in persons with Parkinson disease (PD).

METHODS

A cross-sectional case-control study was carried out. Assessments included the List of 90 Symptoms somatic factor (SCL-90-R SOM), Movement Disorder Society Unified Parkinson's Ratings Scale (MDS-UPDRS), Non-Motor Symptom Scale (NMSS), Montreal Cognitive Assessment (MoCA), and Parkinson Questionnaire-8 (PDQ-8).

RESULTS

A total 93 persons with PD and 93 controls were included. Somatization within the PD group was 2 times more frequent compared to the control group (43% vs 21.5%, P = .003). Persons with PD had higher NMSS total scores (48.6 ± 42.6 vs 28.3 ± 30.4, P = .001). Patients with PD with somatization had worst MDS-UPDRS, NMSS, MoCA, and PDQ-8 (all P < .05).

CONCLUSION

Somatization is more frequent in persons with PD compared to healthy controls. Somatization in PD is associated with nonmotor symptoms and worst quality of life.

Somatization and Coping in Ethnic Minority Recruits

INTRODUCTION

Military service can have beneficial social effects on minorities. However, minority groups are also often at greater risk of somatizing psychological distress and coping maladaptively. In military training this would result in lower mental health of minorities and contribute to higher drop-out rates. We thus examined if recruits with different ethnocultural backgrounds report different somatization levels and coping styles.

MATERIALS AND METHODS

Seven hundred and forty male recruits of the Swiss Armed Forces aged 18-26 took part in a cross-sectional study during basic training. Participants filled out self-rating questionnaires covering sociodemographics, somatization (SCL-90-R), coping styles (INCOPE-2), and social support (F-SozU). The recruits' ethnic self-identification was used to compare three groups: native Swiss (89%); Turkish or Balkan minority (5%); heterogeneous ethnic minority (6%). Group differences in somatization scores were tested with a Kruskal-Wallis test; group differences in coping styles were tested with a multivariate ANCOVA, controlling for the level of social support experienced.

RESULTS

Recruits from the heterogeneous ethnic minority group reported significantly greater levels of somatization than their native Swiss comrades. Coping styles did not differ between the three ethnic groups, but higher levels of social support were associated with better coping.

CONCLUSION

Military doctors ought to place importance on the differential diagnosis of medically unexplained physical symptoms in ethnic minority recruits. This would contribute to minimize the risk of misdiagnosis. Military mental health professionals who counsel recruits reporting somatic symptoms are advised to be sensitized to an ethnic minority status. Physical complaints could mask affective problems or be part of an adjustment disorder symptomatology.

[Non-delusional hypochondriac disorders in old age]

This review aims to present main concepts of hypochondria and 'hypochondriac mood' in old age. Attention is paid to historical and modern positions of old age hypochondria as a meta-syndromic pathology and as an independent mental disorder. Relationships of hypochondriac manifestations with affective variations and anxiety disorders, as well as somatic diseases, organic degenerative brain diseases and vascular disorders are discussed.

Multiple physical symptoms and individual characteristics - A cross-sectional study of the general population

OBJECTIVE

Multiple physical symptoms not attributable to known organic disease are common in all medical fields and associated with major personal and social consequences. This study investigated multiple physical symptoms according to the construct of bodily distress syndrome (BDS) and associated individual characteristics in the general adult population.

METHODS

A nationwide, population-based study of 100,000 randomly selected individuals aged 20 years and older, conducted in 2012. A web-based questionnaire formed the basis of the study and was combined with Danish national registry data on socioeconomic factors and medication and healthcare use.

RESULTS

49,706 individuals completed the questionnaire. After exclusion of women indicating pregnancy, respondents reporting chronic disease and respondents over 65 years of age, 23,331 remained for analysis. Of these 23,331 individuals, 15.5% fulfilled the criteria for BDS. BDS positives were more often younger (20-40 years) and female. Self-rated health and self-reported functional capacity were impaired among these individuals. Fulfilling the BDS criteria was significantly associated with current or former smoking, overweight and obesity, low educational level and income, and unemployment. Moreover, individuals with BDS were more often from ethnic minorities and had higher use of healthcare and medication.

CONCLUSION

Multiple physical symptoms, as captured by the concept of BDS, are common in the general adult population, especially among younger women. Fulfilling the BDS criteria is associated with substantial negative impact on self-perceived health and socioeconomic parameters. Fulfilling BDS criteria is positively associated with health risk behaviors (smoking, overweight and obesity) and higher use of healthcare and medication.

[Impairments of cognitive control in patients with somatoform disorders and their treatment]

AIM

To study impairments of cognitive control in patients with somatoform disorders (SD) and to evaluate the efficacy of recognan in the treatment of this pathology.

MATERIAL AND METHODS

Forty-six patients with SD, aged from 18 to 45 years, were studied. A clinical history, neurological examination, and assessment of autonomic disorders were collected from all patients. For the objectification of the severity of asthenic and emotional disorders, the Subjective Scale of Asthenia (MFI-20), the Hamilton Anxiety Scale (HARS), the Cognitive Emotion Regulation Questionnaire (CERQ were used. A quantitative assessment of impaired attention and impulsivity was performed using the psychophysiological test TOVA. Patients were treated with recognan (citicoline). The control group consisted of 30 healthy people aged from 18 to 45 years.

RESULTS AND CONCLUSION

Patients with SD had specific characteristics of the cognitive sphere, most pronounced in the form of attention disorders. The psychological study showed the higher level of anxiety. In addition, patients with SD were characterized by the low levels of emotional intelligence and cognitive control of emotions compared with the control group. The results of the follow-up study after treatment suggest the high efficacy of recognan in the treatment of SD (improvement was noted in 67.4% of patients). A significant decrease in the severity of autonomic disorders and in indicators characterizing asthenia was established after the treatment.

Hospitalized Patients with Medically Unexplained Physical Symptoms: Clinical Context and Economic Costs of Healthcare Management

Medically Unexplained Physical Symptoms (MUPS) are physical symptoms without a medical explanation. This study collected data from hospitalized patients presenting MUPS, aiming to draw a clinical and socio-demographic profile of patients with MUPS, to explore psychopathological correlations of Somatic Symptoms Disorder (SSD) diagnosis, and to estimate economic costs related to hospital management for MUPS. The cross-sectional study consisted in the evaluation of data referring to hospitalized patients admitted between 2008 and 2018 in a teaching hospital in Northern Italy. A total of 273 patients presenting MUPS have been hospitalized. The sample showed a prevalence of female, married and employed patients. The most frequent wards involved are Neurology, Internal Medicine and Short Unit Stay. The most common symptoms found are headache, pain, syncope and vertigo. There is no evidence that a history of medical disease is associated with a diagnosis of SSD. A personality disorder diagnosis in patients with MUPS was associated with increased probability of having a diagnosis of SSD. A marginally significant positive association emerged with anxiety disorders, but not with depressive disorder. The overall estimated cost of hospitalization for patients with MUPS is 475'409.73 €. The study provides the investigation of a large number of patients with MUPS and a financial estimate of related hospitalization costs.

Medically Unexplained Physical Symptoms in Hospitalized Patients: A 9-Year Retrospective Observational Study

Introduction: "Medically Unexplained Physical Symptoms" (MUPS) defines a subgroup of patients presenting physical symptoms of unclear origin. The study aims to profile clinical and socio-demographic characteristics of patients with MUPS. Materials and Methods: This 9-years observational retrospective study assesses all patients admitted between 2008 and 2016 in the divisions of neurology and gastroenterology. Socio-demographic and clinical variables were evaluated: gender, age, diagnosis or diagnostic hypothesis, presence of psychiatric comorbidities, psychiatric evaluation, pharmacological treatment, number of admissions/visits. Results: Among 2,479 neurological patients 10.1% presented MUPS. Patients were more frequently women (63.5%), with a mean age of about 50 years. Reported symptoms were headache (22.6%), seizures (8.7%), vertigo (5.9%), fibromyalgia (5.5%), paresthesia (5.1%), visual disturbances (5.1%), amnesia (3.9%). The diagnosis was somatoform disorder in 6.3% of cases, conversion disorder in 2.7%, and somatic symptom disorder in 1.5% only. 2,560 outpatients were evaluated in gastroenterology division. 9.6% (n = 248) of patients had MUPS; 62.1% of them were women. The most affected age group ranged between 15 and 45 years. The most frequent diagnoses were functional abdominal pain (50%), dysmotility-like dyspepsia (26.6%), irritable bowel syndrome (10.4%), meteorism of unknown cause (2.4%), hiccup (1.6%), burning mouth syndrome (1.2%). No patients received a diagnosis of somatic symptom disorder. Discussion: Patients with MUPS are more often women, of middle age, with self-referred specific symptomatology. While neurological patients received a diagnostic-therapeutic approach in line with the literature, gastroenterological patients mainly received antipsychotics. A more comprehensive assessment and a development of psychoeducational interventions are needed to improve patients' quality and quantity of life.

The four week time frame for somatic symptom questionnaires reflects subjective symptom burden best

OBJECTIVE

Various questionnaires are available to assess somatic symptom burden, however their assessment time frames vary largely. The aim of this study was to investigate the most relevant assessment time frame for somatic symptoms by relating somatic symptom burden, with varying time frames, to quality of life (QoL) and health anxiety as indicators for clinical relevance of symptoms.

METHODS

This study was performed in data derived from a convenience sample of 3477 participants (age: 48.0 (SD 14.1), 66.4% female) of the Dutch research platform HowNutsAreTheDutch. Symptom burden was assessed using all items from the Patient Health Questionnaire-15 (PHQ-15) and 6 items of the Symptom Checklist-90 SOM (SCL-90 SOM). Five versions of the questionnaire were constructed, which evaluated symptom burden during the past 24h, 1week, 2weeks, 4weeks, and 3months.

RESULTS

Symptom burden significantly increased with each step increase in time frame until 4weeks, with no further increase when comparing 4weeks and 3months. The time frame of 4weeks provided the strongest associations between somatic symptom burden and health anxiety (B=1.635; 95%CI: 1.368 to 1.938; p≤0.001). This was also true when analysing the association between QoL and the symptom groups of musculoskeletal (B=-1.54; 95%CI: -1.93 to -1.16;p≤0.001) and gastrointestinal symptoms (B=-0.71; 95%CI: -0.96 to -0.47;p≤0.001).

CONCLUSION

An assessment time frame of 4weeks for somatic symptom questionnaires reflects clinically relevant somatic symptom burden in terms of QoL and health anxiety best, followed by the 3months' time frame.
