From culture to symptom: Testing a structural model of "Chinese somatization"

Toward Centrality Evaluation of Yearning Symptoms for Prolonged Grief Disorder: A Cross-Cultural Approach

BACKGROUND

The new ICD-11 diagnosis of prolonged grief disorder (PGD) is characterized by the prominent role of yearning as hallmark symptom. A secondary analysis of eight international datasets on PGD was conducted to evaluate this assumption. Additionally, cross-cultural comparison explored whether the centrality of yearning differs across world regions.

METHODS

Primary studies originated from German-speaking countries (n = 4 samples), other European countries and Israel (n = 3 samples), as well as China (n = 1 samples). Different PGD measures were used, including yearning and longing as symptoms. For the centrality assessment of yearning, PGD symptoms were ranked by their factor loadings from confirmatory factor analyses, followed by statistical testing to determine significant differences between yearning and other symptoms of PGD in their factor loading estimates. Subsequently, ranking positions of yearning in three world regions (German-speaking, other Europe-Israel, and China) were compared. Finally, proxy thresholds for individuals at high-risk states for PGD were defined for the different datasets, and sensitivity-specificity analyses of yearning were performed.

RESULTS

Yearning was ranked high in five out of 12 models tested. In the German-speaking region, it was predominantly ranked among the most central symptoms; in the other Europe-Israel region as well as China, it tended to fall into the middle or lower rankings of symptom centrality. Sensitivity values were consistently high, while specificity values indicated moderate levels.

DISCUSSION

In line with previous research on the general outcomes of grief, the present study showed that yearning may be subject to a culture-specific distribution. Other central symptoms such as feeling as if a part of oneself died have also been shown to potentially play a central role in PGD across world regions. On the other hand, the sensitivity-specificity analyses revealed that yearning can be considered a significant (diagnostically highly sensitive) symptom for individuals in high-risk states for PGD, although it has only moderate specificity (i.e., its absence does not necessarily indicate individuals experiencing normative grief). Nonetheless, a culture-sensitive approach to psychopathology should consider the cultural differences in the centrality of this symptom group. More research is needed to better understand the role of yearning and its determinants across world regions.

A study of somatization symptoms and low-frequency amplitude fluctuations of emotional memory in adolescent depression

Studies have revealed that somatization symptoms are associated with emotional memory in adolescents with depressive disorders. This study investigated somatization symptoms and emotional memory among adolescents with depressive disorders using low-frequency amplitude fluctuations (ALFF). Participants were categorized into the somatization symptoms (FSS) group, non-FSS group and healthy control group (HC). The correctness of negative picture re-recognition was higher in the FFS and HC group than in the non-FSS group. The right superior occipital gyrus and right inferior temporal gyrus were significantly larger in the FSS group than those in the non-FSS and HC groups. Additionally, the ALFF in the superior occipital and inferior temporal gyrus were positively correlated with CSI score. Furthermore, the ALFF values in the temporal region positively correlated with correct negative image re-recognition. The negative image re-recognition rate was positively correlated with the ALFF in the left and right middle occipital gyri. These findings indicated that somatization symptoms in adolescent depression are associated with the superior occipital gyrus and inferior temporal gyrus. Notably, somatization symptoms play a role in memory bias within depressive disorders, with middle occipital and inferior temporal gyri potentially serving as significant brain regions.

Sex differences in the association between suicidal ideation and neurocognitive function in Chinese patients with schizophrenia

There is increasing evidence that sex differences exist in many clinical manifestations of patients with schizophrenia, including suicidal ideation (SI) and neurocognitive function. The present study was performed to explore the sex differences in the association between SI and neurocognitive function in Chinese patients with schizophrenia. A total of 1188 inpatients with schizophrenia were recruited from multicenter psychiatric hospitals. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was utilized to evaluate the neurocognitive function of all patients. The Positive and Negative Syndrome Scale (PANSS) was utilized to assess the psychopathology of patients. The Beck Scale for Suicide Ideation (BSSI) was used to assess the severity of SI. In male patients, the suicide risk score was significantly associated with PANSS negative symptoms (r = 0.167, p = 0.043), visuospatial subscale (r = - 0.261, p = 0.001), and RBANS total scores (r = - 0.172, p = 0.037). Furthermore, multivariate linear regression analysis showed that the visuospatial subscale (β = - 0.490, t = - 3.273, p = 0.001) was independently associated with the suicide risk score in male patients. In female patients, the suicide risk score was significantly correlated with PANSS positive symptoms (r = 0.249, p = 0.021), negative symptoms (r = 0.394, p < 0.001), general psychopathology (r = 0.276, p = 0.01) and PANSS total score (r = 0.365, p = 0.001). Multivariate linear regression analysis showed that PANSS negative symptoms (β = 1.849, t = 3.933, p = 0.001) were significantly associated with suicide risk scores in female patients. Our findings indicate that there are sex differences in the association between SI and neurocognitive function in patients with schizophrenia. Based on the findings of our study, gender-specific prevention and intervention strategies may make a difference in reducing SI in Chinese schizophrenia patients.

Interoception, somatic symptoms, and somatization tendency in Chinese individuals with subsyndromal depression: A follow-up study

Interoception refers to the sensation and perception of internal bodily sensations, and may be related to depressive symptoms. Schemata concerning the body vary across different cultures and may influence interoception and symptom presentations of depression. This study explored the relationship between interoception, depressive symptoms, and schema of somatic focus in Chinese people with subsyndromal depression. Thirty-nine individuals with subsyndromal depression (SD) and 40 healthy controls (HCs) were assessed at baseline and after 3 months. Participants completed the self-report questionnaires for assessing interoceptive sensibility, somatic and psychological symptoms of depression, and somatization tendency. They also completed the heartbeat perception behavioral task for estimating interoceptive accuracy. The results showed that both the SD and the HC groups showed similar interoceptive accuracy, although the SD group showed heightened interoceptive sensibility. The discrepancy between interoceptive sensibility and interoceptive accuracy is termed the interoceptive trait prediction error (ITPE). The ITPE was positive in SD participants but was negative in HCs. In the entire sample, interoceptive sensibility and the ITPE were correlated with somatic symptoms rather than with psychological symptoms of depression. Interoceptive sensibility partially mediated the relationship between somatization tendency and somatic symptoms, after controlling for psychological symptoms of depression. These results remained stable after 3 months. The shortcomings of the present study were a lack of clinical interview to ascertain diagnosis and a short follow-up duration. In conclusion, our study suggests that altered interoception occurs in subsyndromal depression. Interoception is related to somatic symptoms of depression. The schema of body was related to depressive symptoms, partially through interoception, in Chinese people with subsyndromal depression.

A new approach to cultural scripts of trauma sequelae assessment: The sample case of Switzerland

BACKGROUND

The novel concept of cultural scripts of trauma sequelae captures culture-specific expressions of posttraumatic distress (e.g., cognitive, emotional, interpersonal, psychosomatic changes) and their temporal associations. Cultural scripts of trauma sequelae complement pan-cultural (etic) diagnoses, such as posttraumatic stress disorder (PTSD) and Complex PTSD, as well as the cultural syndromes concept.

OBJECTIVE

This study aimed to develop the cultural scripts of trauma inventory (CSTI) for German-speaking Switzerland and to explore temporal associations of script elements.

METHOD

Five semi-structured focus groups were conducted with psychotraumatologists (n = 8) and Swiss trauma survivors (n = 7). The interview schedule included open questions about different domains of potential posttraumatic changes (emotions, cognitions, worldviews, interpersonal relationships, body-related experiences, behavior, and growth). Data were analyzed using qualitative content analysis.

RESULTS

The Swiss CSTI includes 57 emic elements that represent salient trauma sequelae (30 conformed with a theoretically derived item pool, 27 were newly phrased). Temporal script associations were visualized in a network, whereby self-deprecation, the urge to function and overcompensate, and the urge to hide and endure suffering had the highest number of connections.

CONCLUSION

While many posttraumatic changes identified in the present work seem to mirror pan-cultural phenomena represented in the Complex PTSD concept (e.g., self-deprecation), others (e.g., urge to function and perform, urge to hide and endure suffering) may be prominently related to Swiss culture with its value orientations. Knowledge about cultural scripts of trauma sequelae may provide a culture-specific framework that can help to understand individual experiences of distress and enable mental health practitioners to administer culturally sensitive interventions. Pending further validation, the Swiss CSTI bears the potential to advance culture-sensitive assessment of trauma sequelae.

Cognitive-behavioral therapy for patients with somatoform disorders: A pilot preliminary randomized controlled trial

Background and objective: Cognitive-behavioral therapy (CBT) for somatoform disorders (SFDs) is understudied in China. Western findings may not be applicable to Chinese culture. This preliminary study evaluated the efficacy of CBT for patients in China, relative to treatment-as-usual (TAU). Methods: Seventy patients with SFDs randomly received either combined CBT and TAU (CBT + TAU), or TAU alone between January 2018 to May 2019. The CBT + TAU group received 12 weekly individual 50-minute CBT sessions. Participants were blindly assessed at 4 timepoints (baseline, week 6, end of treatment: week 12; 12 weeks post-treatment: week 24) using the following outcome measures: SQSS (Self-screening Questionnaire for Somatic Symptoms); PHQ-15 (Patient-Health-Questionnaire-15) and the WI (Whiteley Index); GAD-7 (General Anxiety Disorder-7); HAMD-17 (Hamilton Depression Rating Scale-17); Family Burden Interview Schedule (FBIS); Sheehan Disability Scale (SDS); and the Short Form of Quality-of-Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF). The primary endpoint was the difference between the SQSS total score at week 24 and the baseline. A mixed model for repeated measures was used to analyze inter- and intra-group changes from the baseline. Results: At week 24, The least-squares mean (LSM) change of the total score on the SQSS was -18.87 points and -9.69 points, respectively in the CBT + TAU group and in the TAU group (LSM difference, -9.18 points; 95% confidence interval, -15.72 to -2.64; P = 0.0068). At week 24, the LSM changes from baseline in the WI, HAMD, PHQ15, FBIS and SDS total scores were significantly different between the two groups, however, there was no significant difference in the Q-LES-Q-SF. The SQSS of group effect sizes were 0.63 at 24 weeks. The dropout rates of the CBT + TAU and TAU groups were comparable (22.9% and 19.3%). Conclusions: These preliminary findings suggest that CBT may be helpful for improving the symptoms of patients with SFDs in China.

Correlates of jaw functional limitation, somatization and psychological distress among different temporomandibular disorder diagnostic subtypes

OBJECTIVES

This study investigated the jaw functional status and severity of somatic/psychological symptoms in different Diagnostic Criteria for temporomandibular disorders (DC/TMD) diagnostic subtypes and established the correlates between jaw functional limitation, somatization, depression and anxiety.

METHODS

Data were accrued from consecutive 'first-visit' patients seeking TMD treatment at a university-based oral medicine/diagnosis clinic. Axis I physical TMD diagnoses were derived using the DC/TMD methodology and patients were categorized into pain-related (PT), intra-articular (IT) and combined (CT) TMD groups. Axis II measures were also administered and included the Jaw Functional Limitation Scale-20 (JFLS-20), Patient Health Questionnaire-15 and 9 (PHQ-15 and PHQ-9) and General Anxiety Disorder Scale-7 (GAD-7). Chi-square/Kruskal-Wallis tests and Spearman's correlation were employed for statistical evaluations (α = .05).

RESULTS

The final dataset consisted of 772 TMD patients (mean age of 37.7 ± 15.9 years; 70.2% females). The prevalence of PT, IT and CT was 11.9%, 15.7% and 72.4%, respectively. Significant differences in functional jaw limitations, somatization, depression (CT, PT > IT) and anxiety (CT > PT, IT) were observed. Moderate-to-severe somatization, depression and anxiety were detected in 12.6%-15.7% of patients. For all three TMD groups, JFLS global scale/subscale scores were weakly associated with somatization, depression and anxiety scores (rs  < 0.4). Moderate-to-strong correlations were noted between somatization, depression and anxiety (rs  = 0.50-0.74).

CONCLUSIONS

Functional jaw limitations were associated with painful TMDs but appear to be unrelated to somatization and psychological distress. Somatization and depression/anxiety were moderately correlated, underscoring the importance of somatic symptom screening when managing TMD patients.

Somatic symptom distress and ICD-11 prolonged grief in a large intercultural sample

Background: Grief is a multi-faceted experience including emotional, social, and physical reactions. Research in ICD-11 prolonged grief disorder (PGD) in different cultural contexts has revealed different or potentially missing grief symptoms that may be relevant.Objective: This study thus aimed to explore the prevalence of somatic symptom distress and its associations with grief and negative affect in a culturally diverse sample of bereaved individuals with symptoms of PGD.Methods: Based on cross-sectional survey data from the Measurement and Assessment of Grief (MAGIC) project, this study included 1337 participants (mean age 23.79 yrs, 76.1% female) from three regions (USA: 62.3%, Turkey/Iran: 24.2%, Cyprus/Greece: 13.5%), who experienced a loss of a significant other. Associations between somatic symptom distress (Somatic Symptom Scale, SSS-8), symptoms of PGD (International Prolonged Grief Disorder Scale, IPGDS-33), anxiety (Generalized Anxiety Disorder Questionnaire, GAD-7), depression (Patient Health Questionnaire, PHQ-9) as well as demographic and loss related characteristics were investigated. Three hundred and thirteen participants (23.4%) scored above the proposed cut-off for clinically severe PGD.Results: 'High' or 'very high' levels of somatic symptom distress were more frequent in a possible PGD group (58.2%), than in a non-PGD group (22.4%), p < .001, as divided per cut-off in the IPGDS. In a multiple regression analysis, PGD symptoms were significantly but weakly associated with somatic symptom distress (β = 0.08, p < .001) beyond demographics, loss-related variables, and negative affect. Negative affect (anxiety and depression) mediated the relationship of PGD symptoms with somatic symptom distress and the indirect effect explained 58% of the variance.Conclusions: High levels of somatic symptom distress can be observed in a substantial proportion of bereaved across cultures. Our findings suggest that PGD is related to somatic symptom distress partly and indirectly through facets of negative affect.

Characteristics and correlation of gray matter volume and somatic symptoms in adolescent patients with depressive disorder

Background

Adolescent patients with depressive disorders commonly exhibit somatic symptoms, which have a significant negative impact on their treatment and prognosis. Despite this, specific brain imaging characteristics of these symptoms have been poorly studied.

Methods

The Hamilton Depression Rating scale (HAMD-17), Children's Functional Somatization scale (CSI), and Toronto Alexithymia scale (TAS) were used to evaluate the clinical symptoms of adolescent depression. We analyzed the correlation between brain gray matter volume (GMV) and clinical symptoms in adolescent patients with depression and somatic symptoms.

Results

The depression subgroups with and without functional somatic symptoms (FSS) had higher scores on the HAMD-17, CSI, and TAS than the normal control group. The group with FSS had higher HAMD-17, CSI, and TAS scores than the depression group without FSS (p < 0.05). CSI and TAS scores were positively correlated (r = 0.378, p < 0.05). The GMV of the right supplementary motor area was higher in the depression groups with and without FSSs than in the normal control group, and the GMV was higher in the group without FSS than in the group with FSS (F = 29.394, p < 0.05). The GMV of the right supplementary motor area was negatively correlated with CSI in the depressed group with FSS (r = -0.376, p < 0.05). In the group with depression exhibiting FSS, CSI scores were positively correlated with GMV of the middle occipital gyrus (pr = 0.665, p = 0.0001), and TAS scores were positively correlated with GMV of the caudate nucleus (pr = 0.551, p = 0.001).

Conclusion

Somatic symptoms of adolescent depressive disorder are associated with alexithymia; moreover, somatic symptoms and alexithymia in adolescent patients with depressive disorders are correlated with GMV changes in different brain regions.

Vicarious experiences of touch (mirror touch) in a Chinese sample: Cross-cultural and individual differences

Mirror-touch synaesthesia (MTS) refers to tactile sensations people have on their own body when they see another person being touched. This trait has been linked to individual differences in computing body awareness and ownership (e.g., on questionnaires, cognitive tests) as well as differences in the brain. Here it is assessed for the first time in a non-Western (Chinese) population. Study 1 shows that reports of mirror-touch are elevated in a Chinese sample (N = 298) relative to comparable Western samples shown identical stimuli. In other respects, they are qualitatively similar (e.g., showing a difference between whether humans or inanimate objects are touched) and, overall, these differences could not be attributed to an acquiescence bias. The Chinese sample also completed a battery of questionnaires relating to body awareness and social-emotional functioning including mental health (Study 2) and had participated in brain imaging (the structural scans were analysed using voxel-based morphometry in Study 3). Participants reporting higher levels of mirror touch reported higher levels of anxiety. There were no reliable differences in the VBM analysis. It is suggested instead that cross-cultural differences in embodied cognition can manifest themselves in different rates of vicarious experience such as mirror touch.

Impact of the COVID-19 pandemic on psychological distress and biological rhythm in China’s general population: A path analysis model

Objective

When facing major emergency public accidents, men and women may react differently. Our research aimed to assess the influence of gender difference on social support, information preference, biological rhythm, psychological distress, and the possible interaction among these factors during the COVID-19 pandemic.

Methods

In this cross-sectional study, 3,237 respondents aged 12 years and older finished the online survey. Levels of social support, information preference, biological rhythm, and psychological distress were assessed using validated scales. A path analysis was conducted to explore possible associations among these variables.

Results

The path analysis indicated that women with high levels of social support had a lower possibility of biological rhythm disorders and lower levels of somatization symptoms of psychological distress during the COVID-19 pandemic. The influence of social support on somatization symptoms was exerted via biological rhythm. Women tended to believe both negative and positive information, while men preferred more extreme information.

Conclusion

Our results highlighted gender difference in study variables during the COVID-19 pandemic and the importance of social support in alleviating psychological distress and biological rhythm disorders. Moreover, we confirmed that information preference differed significantly by somatization symptoms of psychological distress, suggesting extra efforts to provide more individualized epidemic information. Longitudinal research is required to further explore casual inferences.

Menopause-Related Symptoms and Influencing Factors in Mosuo, Yi, and Han Middle-Aged Women in China

Although previous studies showed that women’s menopause-related symptoms varied in different ethnic groups and countries, and were affected by specific social and cultural factors, few studies have been conducted to explore menopause-related symptoms and its influencing factors in middle-aged women among ethnic groups in China. This study aimed to explore the characteristics of menopause-related symptoms and its influencing factors among Mosuo, Yi, and Han women in Yongning area of Yunnan province, China. A cross-cultural design by snowball sampling method was used to recruit 208 women aged 40–60 from Yongning Township, Ninglang County, Yunnan province, China. The 11-item Menopause Rating Scale (MRS) was used to assess menopause-related symptoms. Compared with Yi and Han women, Mosuo women were accorded the highest family status. Multiple linear regression analyses showed that ethnicity, age, family support, and family decision-making patterns were associated with the severity of menopause-related symptoms. Yi and Han women had more severe menopause-related symptoms than Mosuo women. Among the three groups, women living in “female-dominated” and “co-deliberated” households had significantly lower scores of menopause-related symptoms than those in “male-dominated” households. This study indicates that menopause-related symptoms vary among middle-aged women in different ethnic groups. A higher level of female status in the family and family support may be protective factors of menopause-related symptoms in middle-aged women.

The New ICD-11 Prolonged Grief Disorder Guidelines in Japan: Findings and Implications from Key Informant Interviews

Prolonged grief disorder (PGD) is a new mental health disorder, recently introduced in the International Classification of Diseases (ICD-11), World Health Organization Classification of Diseases (WHO). The new ICD-11 guidelines reflect an emerging wave of interest in the global applicability of mental disorders. However, the selection of diagnostic core features in different cultural contexts has yet to be determined. Currently, there is debate in the field over the global applicability of these guidelines. Using semi-structured interviews with 14 key informants, we explored the acceptability of ICD-11 guidelines for PGD according to Japanese health professionals as key informants. The interviews revealed symptoms of grief possibly missing in the ICD-11 PGD guidelines including somatization and concepts such as hole in the heart. Additionally, sociocultural barriers such as stigma and beliefs about the social desirability of emotions may challenge patients' and clinicians' acceptance of the new ICD-11 criteria.

Age-Related Differences of Rumination on the Loneliness-Depression Relationship: Evidence From a Population-Representative Cohort

Background and Objectives

This study examined the association of loneliness with depressive symptoms across various age groups. Loneliness is a significant risk factor for precipitating depressive symptoms. Rumination, a mechanism that underpins depression, can become intense when a person feels lonely. In addition, age is a major factor associated with changes in mental and physical health. Thus, the importance of rumination and age in moderating the loneliness-depression link were investigated.

Research Design and Methods

This cross-sectional study was conducted during the acute phase of the coronavirus disease 2019 pandemic in Hong Kong (February 27 to March 17, 2020). A population-representative sample of 1,972 people (1,107 females; 18-92 years of age) was recruited and interviewed via telephone through random digit dialing. This sample included 394 younger adults (18-30 years), 1,106 middle-aged adults (31-64 years), and 472 older adults (65 years or above). Respondents reported depressive symptoms, subjective loneliness, state rumination, and sociodemographic factors.

Results

Loneliness and rumination were positively associated with depressive symptoms, and they significantly interacted in predicting cognitive-affective symptoms. Further analysis of age showed that the interaction was significant only in middle-aged adults and older adults. Both rumination and age interacted with loneliness, respectively, in predicting cognitive-affective symptoms.

Discussion and Implications

These findings indicate that the strength of the association between loneliness and the cognitive-affective symptoms of depression depends on rumination levels and age. An intervention to regulate rumination offers a feasible direction for health care and social care aimed at improving older adults' mental health.

A randomized controlled trial on the comparative effectiveness of mindfulness-based cognitive therapy and health qigong-based cognitive therapy among Chinese people with depression and anxiety disorders

BACKGROUND

The goal of this study was to investigate treatment outcome and related intervention processes of mindfulness-based cognitive therapy versus health qigong-based cognitive therapy versus waitlist control among individuals with mood disorders.

METHODS

A total of 187 individuals with mood disorders were randomized and allocated into mindfulness-based cognitive therapy, health qigong-based cognitive therapy, or waitlist control groups. All participants were assessed at three time points with regard to depressive and anxiety symptoms, physical and mental health status, perceived stress, sleep quality, and self-efficacy. Linear mixed models analysis was used to test the individual growth model by studying the longitudinal data.

RESULTS

Mindfulness-based cognitive therapy and health qigong-based cognitive therapy both produced greater improvements on all outcome measures as compared with waitlist control. Relatively, more reductions of mood symptoms were observed in the health qigong-based cognitive therapy group as compared with the mindfulness-based cognitive therapy group. Health qigong-based cognitive therapy is more conducive to physical health status whereas mindfulness-based cognitive therapy has more favorable mental health outcomes. Individual growth curve models indicated that alterations in perceived stress was the common predictor of mood changes in both intervention groups.

CONCLUSIONS

The predominant emphasis on physical health in health qigong-based cognitive therapy makes it more acceptable and effective than mindfulness-based cognitive therapy as applied in Chinese individuals with mood disorders. The influence of Chinese culture is discussed.

Cross-cultural comparison of symptom networks in late-life major depressive disorder: Yoruba Africans and the Spanish Population

BACKGROUND

The concept of European psychologisation of depression versus somatisation in non-European populations has been the basis of several studies of cultural psychopathology in the general population. Little is currently known about cross-cultural differences and similarities in late-life depression symptom reporting. We cross-culturally compared symptom reporting in the context of Major Depressive Disorder (MDD) among community-dwelling older adults from Spain and Nigeria.

METHODS

We relied on data from two household multistage probability samples comprising 3,715 persons aged 65 years or older in the Spanish and Nigerian populations. All participants underwent assessments for MDD using the World Mental Health Survey version of the Composite International Diagnostic Interview. Cross-cultural comparison of broad somatic and psychological categories as well as relationship and influence of individual symptoms were analysed using the Symptom Network Analysis approach.

RESULTS

Current MDD was diagnosed in 232 and 195 older persons from Spain and Nigeria, respectively. The symptom network of the two samples were invariant in terms of global strength, S(G_SPAIN , G_NIGERIA ) = 7.56, P = .06, with psychological and somatic symptoms demonstrating centrality in both countries. However, country-specific relationships and influence of individual symptoms were found in the network structure of both samples, M(G_SPAIN , G_NIGERIA ) = 2.95, P < .01.

CONCLUSION

Broad somatic and psychological symptoms categories contributed to the structural network of older Africans and their peers from the Spanish population. Variations in the relationship and influence of individual symptoms suggests that the functional and "communicative" role of individual symptoms may be differentiated by context specific imperatives.

Integrating Symptoms Into the Middle-Range Theory of Self-Care of Chronic Illness

The Middle-Range Theory of Self-Care of Chronic Illness has been used widely since it was first published in 2012. With the goal of theoretical refinement in mind, we evaluated the theory to identify areas where the theory lacked clarity and could be improved. The concept of self-care monitoring was determined to be underdeveloped. We do not yet know how the process of symptom monitoring influences the symptom appraisal process. Also, the manner in which self-care monitoring and self-care management are associated was thought to need refinement. As both of these issues relate to symptoms, we decided to enrich the Middle-Range Theory with knowledge from theories about symptoms. Here, we propose a revision to the Middle-Range Theory of Self-Care of Chronic Illness where symptoms are clearly integrated with the self-care behaviors of self-care maintenance, monitoring, and management.

Orthorexia Nervosa in China: An Exploration of Phenomenology and Clinical Correlates Among University Students

Orthorexia nervosa, characterized by pathological preoccupation with healthy eating and food purity, is conceptualized as being linked to cultural concepts of health pervasive in contemporary Western societies. However, little is known about the phenomenology and clinical correlates of orthorexia nervosa in non-Western cultures. The current study examined symptoms of orthorexia nervosa, obsessive-compulsive disorder, depression, anxiety, and fear of negative evaluation among 418 Chinese university students. A minority of participants endorsed frequent or impairing orthorexia nervosa symptoms, and females reported slightly higher severity of orthorexia nervosa symptoms than males. Orthorexia nervosa symptom severity was moderately associated with obsessive-compulsive and anxiety symptoms, and weakly associated with depressive symptoms and fear of negative evaluation. Although this study generates initial data about orthorexia nervosa among Chinese students, further research is greatly needed to establish the prevalence and clinical characteristics of orthorexia nervosa in Western and Non-Western cultures.

Distressing encounters in the context of climate change: Idioms of distress, determinants, and responses to distress in Tuvalu

Across the globe there is a critical need for culturally informed and locally valid approaches to mental health assessment and intervention, particularly among disadvantaged and marginalized populations. To be optimally effective, such approaches must be informed by a sound understanding of locally relevant idioms of distress and its determinants, including those caused or exacerbated by global power disparities and structural inequities. Climate change, arising due to anthropogenic sources located predominantly in industrialized nations, is one potential determinant of distress having disproportionate adverse impacts on already marginalized populations. The present study formed part of a broader project examining the intersections of culture, climate change, and distress in the Polynesian nation of Tuvalu - a focal point of global concern over the human costs of climate change. The study explored determinants and idioms of distress and culturally prescribed responses to coping with distress. Results are based on fieldwork conducted in 2015 entailing semi-structured interviews with 16 key informants and 23 lay residents of Funafuti atoll, recruited using maximal variation purposive sampling. Findings are examined in consideration of the unfolding impacts of climate change and the threat it portends for the future, both of which were identified as salient determinants of distress, in keeping with theorized relationships between climate change and mental health. The study underscores the necessity of attending to the relationships between global forces, local cultures, and individual experiences of distress, as efforts to provide access to culturally informed social and mental health services expand globally.

Assessment of Burden Among Family Caregivers of Schizophrenia: Psychometric Testing for Short-Form Zarit Burden Interviews

Objective: Although various short forms of Zarit Burden Interview (ZBI) have been developed, there is a lack of standard psychometric testing and comparison among them. The study aims to examine the psychometric properties of ten short versions of the most frequently used ZBI among a sample of schizophrenia caregivers and to find the one with the best performance.

Methods: Cross-sectional door-to-door survey of ZBI-22 and a series of validated instrument data from 327 family caregivers of schizophrenia patients in a Chinese rural community were conducted from October 2015 to January 2016. Reliability was assessed using McDonald's omega coefficient (ω). Validity including concurrent validity, known group's validity, and criterion validity were assessed by Spearman correlations and Mann-Whitney U tests. Overall discrimination ability was evaluated using the area under the receiver operating characteristic curve (AUC).

Results: Reliability was generally good for all short forms (ω = 0.69–0.84), except for the Gort ZBI-4 (ω = 0.58), which is acceptable considering its small item numbers. Concurrent validity was good across all various ZBI forms with significant negative correlations with patient's function (r = −0.34 to −0.48, p < 0.01), as well as significant positive correlations with caregiver's depression (r = 0.49–0.65, p < 0.01), and anxiety symptoms (r = 0.45–0.58, p < 0.01). Known groups' validity (carers with disease vs. without disease; carers being parents vs. spouse vs. others) showed inconsistent results among various short forms. Criterion validity was generally good for all short forms with significant positive correlations with Family Burden Interview Schedule (r = 0.67–0.75, p < 0.01), except for the Higginson ZBI-1(r = 0.57, p < 0.01). Discriminative ability was also good for all short forms (AUC range: 0.85–0.99), with various cutpoints proposed. Among all ten short forms, the Ballesteros ZBI-12 and the Gort ZBI-7 outperformed others with almost equally good performance in comprehensive psychometric testing.

Conclusions: This study provides support for the reliability, validity, and discriminative ability of the ten various short forms of ZBI for use among schizophrenia family caregivers, with the Ballesteros ZBI-12 and the Gort ZBI-7 endorsed as the best ones.

The Assessment of Grief in Refugees and Post-conflict Survivors: A Narrative Review of Etic and Emic Research

Background: Prolonged grief disorder (PGD) is a new mental health disorder that will be recognized by the World Health Organization’s disorder classification, the ICD-11, in 2018. Current assessment measures of PGD are largely based on North American and European conceptualizations of grief (etic i.e., from the perspective of the observer). However, research is emerging from communities outside of the Global North, in particular, conflict-exposed communities, exploring local models (emic i.e., from within the cultural group), assessment measures and symptoms of grief. Several reviews have found that refugees have higher rates of mental illness, defined by etic standards as depression, post-traumatic stress disorder (PTSD), anxiety disorders and psychotic symptoms. Yet, presently there are no reviews documenting the assessment of PGD in refugees and post conflict survivors.

Method: This narrative review will provide an overview of studies that assess grief in refugees to (1) identify current assessment measures of grief in refugees (i.e., type and frequency of questionnaires used, whether Global North-based, etic, or locally developed, emic, and the level of cultural adaptation) and (2) to document the variety and rate of grief symptoms identified with Global North standard measures and/or local measures (i.e., the endorsement of standard symptom items and the identification of culturally specific symptoms of grief).

Results: This review revealed 24 studies that assessed disordered grief in refugee or post conflict samples. Studies were heterogeneous in their assessment methods; the majority (n = 17) used an etic approach, four used a combined etic/emic approach, and three used a predominantly emic approach. The rate of disordered grief was high depending on cultural adaptation approach (31–76%) and when standard etic measures were used the disordered grief rate was 32%.

Conclusion: These findings will help to guide future studies to provide accurate assessment of grief in refugee and post conflict populations and has implications for improving cultural knowledge in clinical practice.

Psychiatric Disorders Differently Correlate with Physical Self-Rated Health across Ethnic Groups

In this study, we compared 10 ethnic groups for associations between psychiatric disorders and physical self-rated health (SRH) in the United States. Data came from the Collaborative Psychiatric Epidemiology Surveys (CPES), 2001-2003. The study included 7587 non-Latino White, 4746 African American, 1442 Mexican, 1106 other Hispanic, 656 other Asian, 600 Chinese, 577 Cuban, 520 Vietnamese, 508 Filipino, and 495 Puerto Rican individuals. The Composite International Diagnostic Interview (CIDI) was used to measure psychiatric disorders, including major depressive disorder (MDD), general anxiety disorder (GAD), social phobia, panic disorder, post-traumatic stress disorder (PTSD), alcohol abuse, and binge eating disorders. A single-item measure was used to estimate physical SRH. Demographic (age and gender) and socioeconomic (education and income) factors were also measured. Unadjusted and adjusted correlations between psychiatric disorders and physical SRH were calculated. Major ethnic variations were found in the correlation between psychiatric disorders and physical SRH; as well as the role of demographic and socioeconomic status (SES) factors in explaining these associations. non-Hispanic Whites, Cubans, and African Americans showed more correlations between psychiatric disorders and physical SRH than other ethnic groups. In non-Hispanic Whites, the associations between psychiatric disorders and physical SRH were explained by demographic factors. In African Americans, the link between psychiatric disorders and poor physical SRH were explained by SES indicators. In conclusion, although single-item physical SRH measures are traditionally assumed to reflect the physical health needs of populations, they may also indicate psychiatric disorders in some ethnic groups, such as non-Hispanic Whites, Cubans, and African Americans. Demographic and socioeconomic factors also have differential roles in explaining the link between psychiatric disorders and physical SRH. Physical SRH does not exclusively reflect physical health, and it may be more biased by mental health across some ethnic groups.

Cultural differences in symptom representation for depression and somatization measured by the PHQ between Vietnamese and German psychiatric outpatients

OBJECTIVE

Despite an extensive body of research on somatic symptom presentation among people of East- and Southeast-Asian descent, results are still inconclusive. Examining and comparing symptom presentation in clinically and ethnically well-characterized populations may constitute a step towards understanding symptom presentation between patients with a different cultural background. This study aims to compare Vietnamese and German patients regarding cultural dynamics of symptom presentation upon first admission to a psychiatric outpatient service.

METHODS

110 Vietnamese and 109 German patients seeking psychiatric treatment at two outpatient clinics completed the Patient Health Questionnaire (PHQ). The somatic symptom subscale (PHQ-15), the depression subscale (PHQ-9) and PHQ-subscales examining anxiety and psychosocial stress levels were analyzed and compared for both groups using multivariate analysis of covariance. Regression analysis was utilized to examine the influences of sociodemographic and migration specific factors.

RESULTS

Vietnamese and German patients showed comparable Cronbach's alpha for all subscales. Vietnamese patients endorsed significantly higher levels of somatic symptoms overall and on certain items (as pain-related items, dizziness, and fainting spells) despite similar levels of depression severity in comparison with German patients. Vietnamese patients with poor German language skills showed a significantly higher focus on somatic symptoms.

CONCLUSION

Raising awareness for cultural dynamics of symptom presentation in patients with depression is indispensable. Cross-cultural symptom assessment using the PHQ seems feasible and expands our understanding of depressive and psychosomatic symptoms when assessed by clinicians.

Extending a structural model of somatization to South Koreans: Cultural values, somatization tendency, and the presentation of depressive symptoms

BACKGROUND

Somatization refers to the tendency to emphasize somatic symptoms when experiencing a psychiatric disturbance. This tendency has been widely reported in patients from East Asian cultural contexts suffering from depression. Recent research in two Chinese samples have demonstrated that the local cultural script for depression, involving two aspects-the experience and expression of distress (EED) and conceptualization and communication of distress (CCD)-can be evoked to help explain somatization. Given the beliefs and practices broadly shared across Chinese and South Korean cultural contexts, the current study seeks to replicate this explanatory model in South Koreans.

METHODS

Our sample included 209 psychiatric outpatients from Seoul and Wonju, South Korea. Self-report questionnaires were used to assess somatization tendency, adherence to traditional values, and psychological and somatic symptoms of depression.

RESULTS

Results from SEM showed that the EED and CCD factors of somatization tendency were differently associated with cultural values and somatic symptoms, replicating our previous findings in Chinese outpatients.

LIMITATIONS

The reliance on a brief self-report measure of somatization tendency, not originally designed to assess separate EED and CCD factors, highlights the need for measurement tools for the assessment of cultural scripts in cross-cultural depression research.

CONCLUSIONS

The replication of the Chinese structural model of somatization in South Korea lends empirical support to the view that somatization can be understood as the consequence of specific cultural scripts. These scripts involve the experience and expression of distress as well as culturally meaningful ways in which this distress is conceptualized and communicated to others.
