Psychometric properties of the German version of the Pre-loss Grief Questionnaire (PG-12-R).

This study aimed to develop a German version of the revised Pre-loss Grief Questionnaire (PG-12-R) and examine its factor structure, reliability and validity. The PG-12-R was assessed in a representative German sample (N = 2,515). Of these, 362 (14.4%) reported to have a loved one suffering from an incurable disease and 352 provided full data sets. Principal component factor analysis, scree-plot and parallel analysis were conducted. Results supported a one-factor model of PG-12-R with high internal consistency. Convergent validity was confirmed by negative correlations with psychological well-being and time since diagnosis and positive correlations with a more difficult perception of circumstances surrounding the illness and unpreparedness. The German version of the PG-12-R represents a reliable and valid measurement tool of pre-loss grief. It may be used as a screening measure for high levels of pre-loss grief to identify individuals who may need additional support.

Prolonged grief disorder in ICD-11 and DSM-5-TR: differences in prevalence and diagnostic criteria.

Background: Prolonged grief disorder (PGD) was recently included as a disorder in the ICD-11 and DSM-5-TR. Although both classification systems use the same name, the criteria content, and diagnostic approach vary. This study aimed to estimate the respective prevalence of PGDICD-11 and PGDDSM-5-TR and examine the diagnostic agreement while varying the diagnostic algorithm of PGDICD-11 (bereavement vs. symptom period; varying number of accessory symptoms). Methods: A representative sample of the German general population (N = 2,509) was investigated, of which n=1,071 reported the loss of a close person. PGD symptoms were assessed with the Traumatic Grief Inventory - Self Report Plus (TGI-SR+). Results: The point prevalence of PGD among the bereaved varied between 4.7%-6.8%, depending on the criteria and diagnostic algorithm. The prevalence of PGDDSM-5-TR was significantly lower than the prevalence of PGDICD-11. The diagnostic agreement between both criteria sets was substantial and increased after the number of accessory symptoms for PGDICD-11 was increased from one to three. The most common symptoms were intrusive thoughts/images related to the deceased person, longing for the deceased person, and difficulty accepting the loss. Conclusion: The results demonstrate that the prevalence of PGD significantly varies depending on the application of the diagnostic algorithm and criteria. PGD affects a substantial proportion of the general population and should be addressed by healthcare providers. However, applying the minimum ICD-11 criteria could lead overestimating the prevalence. Therefore, further harmonizing the ICD-11 and DSM-5-TR criteria and diagnostic algorithm for PGD seems appropriate.

Psychological burden of achalasia: Patients' screening rates of depression and anxiety and sex differences.

OBJECTIVE: Achalasia is associated with reduced quality of life in affected patients but research regarding the psychological burden of achalasia in terms of depression and anxiety is scarce. The current study therefore aims to investigate rates of depression and anxiety in patients with achalasia in relation to prevalence rates in the general population and to examine the extent to which achalasia-related characteristics (time since diagnosis, symptom load, achalasia-related quality of life, treatment history) predict symptoms of depression and anxiety. METHODS: Using validated screening instruments, rates of depression and anxiety were assessed in a cross-sectional survey of a sample of 993 patients with achalasia and compared to population controls stratified by age and sex. Associations between depression and anxiety and achalasia-related factors were explored using linear regression. RESULTS: Compared to population controls, screening rates of female patients with achalasia were between 3.04 (p = .004) and 7.87 (p < .001) times higher for depression and 3.10 (p < .001) times higher for anxiety, respectively. No significant differences were found for male patients with achalasia. Both achalasia-related quality of life and symptom load were independently related to impaired mental health. CONCLUSION: Women appear to be specifically affected by the psychological burden of achalasia, pointing to sex-specific or gendered experiences of the disease. In addition to symptom reduction, psychological support may prove beneficial for improving the well-being of patients with achalasia.

Stigmatization profiles and psychological distress in people at high risk of infection with COVID-19 -A study conducted in Germany from March to August 2021.

COVID-19-related stigmatization of affected people or people at risk of infection has been shown to enhance the reluctance of affected individuals to use health services and reduce their mental health. It is thus highly important to gain a thorough understanding of COVID-19-related stigmatization. The present study's first aim was to explore stigmatization profiles of experienced stigmatization (anticipated stigmatization, internalized stigmatization, enacted stigmatization, disclosure concerns) and stigmatization practices in 371 German people at high risk of infection using latent class analyses. The second aim was to investigate the relationship between stigmatization profiles and psychological distress via multiple regression analysis taking into account other possible negative and positive risk factors. Our results showed two stigmatization profiles: "high stigmatization group" and "low stigmatization group". Belonging to the "high stigmatization group" was significantly correlated with higher levels of psychological distress. Other risk factors significantly related to psychological distress were mental health disorders in the past, exposure to COVID-19, fear related to COVID-19, perceived risk of being infected, lower perceived self-efficacy, and lower subjective knowledge about COVID-19.

Linguistic predictors of symptom change in an internet-based cognitive behavioural intervention for prolonged grief symptoms.

This study investigates linguistic predictors of reduction in prolonged grief symptoms following a writing intervention in an internet-based cognitive behavioural therapy for people bereaved by cancer. Data stem from a randomized control clinical trial with 70 people. The Linguistic Inquiry and Word Count program was used to analyse patient language. Absolute change scores and reliable change index were used to calculate reduction in grief symptoms and clinical significant change. Best subset regression and Mann-Whitney U tests were conducted. A higher reduction of prolonged grief symptoms was correlated with more social words in the first module (ß = -.22, p = .042), less risk (ß = .33, p = .002) and body words (ß = .22, p = .048) in the second module and more time words in the third module (ß = -.26, p = .018). Patients with clinically significant change showed a higher median in function words in the first module (p = .019), a lower median in risk words in the second module (p = .019) and a higher median in assent words in the last module (p = .014) compared to patients without clinically significant change. Findings suggest that it may be beneficial for therapists to encourage a more detailed description of patients' relationship with their deceased relative during the first module, a change in perspective during the second module and a summary of past, present and future aspects at the end of therapy. Future studies should include mediation analyses to allow causal attribution of the studied effects.

Factors Associated With Treatment Response in an Internet-Based Intervention for Prolonged Grief Disorder After Cancer Bereavement.

Internet-based psychological interventions have proven effective in the treatment of prolonged grief disorder (PGD). Yet, some patients do not benefit from treatment in a clinically significant way. We aimed to examine predictors of symptom reduction in an Internet-based intervention for PGD after cancer bereavement, in order to identify possible treatment mechanisms and discern directions for future intervention design. A secondary analysis of data from a randomized wait-list controlled trial on an Internet-based intervention for PGD after cancer bereavement was conducted. Multiple regression models were used (1) to test for the influence of pretreatment PGD, working alliance, avoidance and gender on PGD symptom reduction; and (2) to explore further predictors of treatment success with a best subset selection protocol. The regression models explained 18% (Model 1) and 34% (Model 2) of variance in symptom reduction. Participants with more favorable symptom change had more severe pretreatment PGD scores and better working alliance. Those with lower social support and less posttraumatic growth experienced more PGD symptom change. In conclusion, therapeutic alliance is an important factor that should be monitored and fostered. Findings regarding social support and posttraumatic growth need further replication and clarification.

Factors associated with pre-loss grief and preparedness in relatives of people with cancer during the COVID-19 pandemic: A cross-sectional study.

OBJECTIVES: Before the loss of a loved one to cancer, relatives have time to adapt to the impending death. However, due to the current COVID-19 pandemic, adjustment to an imminent death may be more difficult. This study investigates factors related to pre-loss grief and preparedness during the COVID-19 pandemic and their relationship with COVID-19 related fears. METHODS: Data of 299 participants from a cross-sectional study was used. Participants were included if they were relatives of people with cancer, spoke German and were at least 18 years. Multivariate linear regression analyses were conducted to measure the relationship between predictors (dysfunctional coping, emotion-focused coping, problem-focused coping, attachment anxiety, attachment avoidance, COVID-19 related fears, prognosis, perceived depth of the relationship, perceived conflict in the relationship, health status) and pre-loss grief, preparedness for caregiving and preparedness for death as the dependent variables. RESULTS: Perceived depth (ß = .365, p < .001), COVID-19 related fears (ß = .141, p = .002), prognosis for death (ß = .241, p < .001), dysfunctional coping strategies (ß = .281, p < .001) and emotion-focused coping strategies (ß = -.320, p < .001) significantly predicted pre-loss grief. Prognosis for death (ß = .347, p < .001), dysfunctional coping strategies (ß = -.229, p < .001), emotion-focused coping strategies (ß = .242, p < .001), COVID-19 related fears (ß = -.112, p = .037) and health status (ß = .123, p = .025) significantly predicted preparedness for death. Dysfunctional coping (ß = -.147, p = .009), problem-focused coping (ß = .162, p = .009), emotion-focused coping (ß = .148, p = .017), COVID-19 related fears (ß = -.151, p = .006), attachment anxiety (ß = -.169, p = .003), perceived conflict in the relationship with the patient with cancer (ß = -.164, p = .004), perceived depth in the relationship (ß = .116, p = .048) and health status (ß = .157, p = .003) significantly predicted preparedness for caregiving. CONCLUSIONS: This study shows COVID-19 pandemic impacts on the grieving process of relatives of patients with cancer. Consequently, screening for pre-loss grief, preparedness and their associated factors may help provide early support for relatives of people with cancer at need. However, further research is needed to help understand the stability of pre-loss grief and preparedness.

The Relationship Between Pre-Loss Grief, Preparedness and Psychological Health Outcomes in Relatives of People With Cancer.

The aim of this study was to examine the simultaneous effects of pre-loss grief, preparedness for death and preparedness for caregiving on different psychological health outcomes in relatives of people with cancer. Two hundred ninety-nine relatives of people with cancer participated in a cross-sectional online survey. Participants were included if they spoke German and were 18 years or older. Multivariate regression analysis was conducted. Pre-loss grief was significantly associated with depression (ß = .388, p < .001), anxiety (ß = .429, p < .001), somatization (ß = .221, p < .001) and satisfaction with life (ß = -.205, p < .001). Preparedness for death was significantly associated with somatization (ß = -.247, p < .001). Results suggest that people with high scores in pre-loss grief and low scores in preparedness for death are in need of early support. Interventions should address pre-loss grief and the various aspects of preparedness for death and take into account the psychological health in relatives of people with cancer. Future studies should investigate underlying mechanisms.

Prevalence, Factor Structure and Correlates of DSM-5-TR Criteria for Prolonged Grief Disorder.

Background: Prolonged Grief Disorder (PGD) is now included in Section II of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR). To understand the health burden and then allocate economic and professional resources, it is necessary to provide epidemiological data for this new disorder. This is especially relevant since the new diagnostic criteria differ from its predecessors, which may affect the generalizability of previous findings. More information on the characteristics of people suffering from PGD is also beneficial to better identify individuals at risk. This study, therefore, aimed to estimate the prevalence of the new PGD criteria in a representative population-based sample, evaluate the factor structure, sociodemographic, and loss-related correlates of PGD caseness and explore possible predictors. Methods: Out of a representative sample of the German general population (N = 2,531), n = 1,371 (54.2%) reported to have experienced a significant loss throughout lifetime. Participants provided sociodemographic data and loss-related characteristics. PGD symptoms were measured using items from the German versions of the Prolonged Grief Scale (PG-13) and the Inventory of Complicated Grief (ICG), which could be matched to the DSM-5-TR criteria for PGD. Results: The conditional prevalence of PGD was 3.4% (n = 47). The most frequently reported symptoms were intense emotional pain and intense yearning or longing for the deceased. The confirmatory factor analysis confirmed a unidimensional model of PGD. Regression analysis demonstrated that time since the death, the relationship to the deceased, and unpreparedness for the death were significant predictors of PGD. Conclusion: Although the prevalence of 3.4% using the new diagnostic criteria is lower than the prevalence previously suggested by a meta-analysis, PGD remains a substantial disorder in the general population. In particular, the loss of a partner or child increases the risk for PGD, as does unpreparedness for the death of a loved one. Clinicians should pay particular attention to these high-risk groups. Further clinical implications are discussed.

Introduction and evaluation of a therapeutic adherence and competence scale for grief-focused cognitive behavioural therapy.

Background: There is no therapeutic competence and adherence scale for grief-focused cognitive behavioural therapy (grief-focused CBT). However, given the growing body of evidence for the efficacy of grief-focused CBT, such a scale is needed both to ensure the internal validity of clinical trials and to facilitate psychotherapy process research. Objective: To develop and undertake a psychometric evaluation of a therapeutic adherence and competence scale for grief-focused CBT. Method: The scale was developed in two steps. (I) Five experts on the treatment of prolonged grief disorder provided feedback on the relevance and appropriateness of the items. The scale was revised to reflect their feedback. The final therapeutic adherence and competence scale for grief (TACs-G) consisted of 15 adherence and 16 competence items. (II) Psychometric evaluation of the TACs-G was based on the rating of 48 randomly selected PG-CBT sessions by two independent raters. The videos were recorded in the context of a randomized controlled trial (RCT; DRKS00012317.) ICC was used to calculate inter-rater reliability and TACs-G stability over time (re-evaluation of 10 sessions after 12 months). Results: The five experts confirmed the relevance and appropriateness of the items. Interrater reliability was found to be high for the total adherence and competence scores (ICC = 0.889 and 0.782, respectively) and moderate to excellent for individual items (ICC = 0.509-1.00). The TACs-G stability over time was found to be strong for both adherence (ICC = 0.970) and competence total scores (ICC = 0.965). Conclusions: The TACs-G for CBT is a reliable instrument that can be used not only to ensure internal validity but is also suited for psychotherapy process studies. Additionally, it provides a valuable database for targeted feedback in training settings. HIGHLIGHTS: This is the first study to report on the development and psychometrical evaluation of a grief-focused adherence and competence scale.Although an increasing number of clinical trials do report the efficacy of grief-focused cognitive-behavioural therapy, none of these studies used a standardized adherence and competence scale to control internal validity.In the present study, we introduced a therapeutic adherence and competence scale for grief (TACs-G) that can be applied efficiently across different research settings (e.g. manipulation check, dissemination), and report results of good to excellent psychometric properties.The scale itself could prove useful beyond the research setting as it could possibly serve as a basis for feedback in training settings.

Predictors of prolonged grief in an internet-based grief therapy for people bereaved by suicide.

Internet-based cognitive-behavioural grief therapy (ICBGT) has proven to be effective for people bereaved by suicide, however the extent to which patients can benefit from therapy seems to differ. This study investigates predictors of initial grief as well as change in grief severity following treatment in an ICBGT for people bereaved by suicide. Data was gathered from a randomized control trial including 57 people participating in a 5-week intervention. Change in grief symptoms was calculated using absolute change scores of grief. In order to examine best overall combination of independent variables, best subset regressions were conducted. Higher levels of pre-test grief were associated with worse sleep quality (ß = 0.32, p = .002), lower self-esteem (ß = -0.37, p = .002), lower support seeking (ß = -0.38, p = .006), and a higher need for social support (ß = 0.28, p = .028). A greater reduction in grief severity was associated with higher self-efficacy (ß = -0.49, p = .001), higher attachment anxiety (ß = -0.31, p = .017) and higher pre-test grief symptoms (ß = -0.39, p = .006). Attention should be paid to the intensity of grief, the attachment style and a positive self-image, as these variables seem to influence the extent, to which patients' symptoms of PGD subside following ICBGT. To specifically target factors of patients that require improvement, further studies are needed.

Loss and grief in elderly people: Results from the LIFE-Adult-Study.

We evaluated 2,865 elderly people to investigate the prevalence of prolonged grief disorder (PGD), examine predictors and mental health correlates. The conditional prevalence of PGD varied between 0.8% and 5.2% (diagnostic algorithm vs. cut-off). PG-13 scores were related to depressive symptoms, sleep disturbances, reduced life satisfaction, and quality of life. Predictors were female gender, less time since death, more losses, having lost a child, partner, or sibling, and less social support. PGD is associated with adverse mental health consequences. Practitioners should pay special attention to elderly women who lost a close loved one and lack social support.

Psychometric properties of the German version of the Depressive and Anxious Avoidance in Prolonged Grief Questionnaire (DAAPGQ).

The Depressive and Anxious Avoidance in Prolonged Grief Questionnaire (DAAPGQ) was developed to measure depressive and anxious avoidance behaviors, which, according to cognitive-behavioral models, are supposed to play an important role in the development and maintenance of prolonged grief. The present study aimed to develop a German version of the DAAPGQ and evaluate its psychometric properties and validity within a representative sample of the German general population (N = 2531). The German-language DAAPGQ was developed using a forward-backward translation procedure. Then, a subsample of individuals who reported having lost a significant other (N = 1371) of a representative sample was assessed with the German DAAPGQ, along with information on sociodemographic characteristics, prolonged grief symptom severity (PG-13), general anxiety (GAD-2) and depression (PHQ-2). The factor structure of the DAAPGQ was evaluated using confirmatory factor analyses, reliability by calculating internal consistency on subscale level and convergent validity by correlations between DAAPQG subscale sores with PG-13, GAD-2 and PHQ-2 sum scores. As expected, a two-factor model with correlated latent variables showed good fit to the data, replicating findings from the original version. Internal consistency was high for both subscales (Cronbach's α .86 and .95, respectively). Convergent validity was established by theoretically expected and statistically significant positive correlations of DAAPGQ subscales with symptom severity of prolonged grief, depression, and anxiety and negative correlations with time since loss. Furthermore, the addition of depressive and anxious avoidance significantly improved the prediction of prolonged grief symptom severity over sociodemographic and loss-related information. In sum, our results suggest that the German-language DAAPGQ is a reliable and valid measure of depressive and anxious avoidance and a useful tool to improve our knowledge on the role of avoidance in prolonged grief. We also provide descriptive data to improve the applicability of the DAAPGQ for individual diagnostics.

Pre-loss grief and preparedness for death among caregivers of terminally ill cancer patients: A systematic review.

BACKGROUND: Cancer is one of the most common causes of death. The period of time between receiving a terminal diagnosis of cancer and the death of a loved one has been operationalized as pre-loss grief and, more recently, as preparedness for death. Originally, grief before loss was thought to have positive effects on the bereavement outcome, but some studies have revealed contradictory findings. This systematic review investigates definitions and measurement tools of pre-loss grief and preparedness for death, as well as the associations of both constructs with caregiver characteristics, pre-loss psychological aspects and post-loss adjustment among caregivers of people living with terminal cancer. METHODS: PubMed/Medline, PsycINFO and Web of Science were searched for studies published up until October 2020. Quantitative empirical studies from peer reviewed journals were included if a measurement tool for pre-loss grief or preparedness for death was used and if they focused on adult caregivers of adult people with cancer in an end-of-life trajectory and were excluded when they were not written in English or were descriptive/qualitative studies. Quality assessment of all studies was performed. RESULTS: Most studies used convenience samples and had a mean number of 725 participants. Overall, 16,326 participants in 35 articles were included and narratively synthesized. High levels of pre-loss grief, as well as low levels of perceived preparedness for death, were associated with poor post-loss adjustment (e.g., prolonged grief, depressive symptoms, etc.). CONCLUSIONS: Caregivers with high levels of pre-loss grief and low levels of preparedness for the death of their loved one would benefit from targeted support for post-loss adjustment. Results are limited by an inconsistent operationalization of both constructs.

Efficacy of an Internet-based cognitive-behavioural grief therapy for people bereaved by suicide: a randomized controlled trial.

Background: The loss of a loved one due to suicide can be a traumatic event associated with prolonged grief and psychological distress. Objective: This study examined the efficacy of an Internet-based cognitive-behavioural grief therapy (ICBGT) specifically for people bereaved by suicide. Methods: In a randomized controlled trial, 58 participants with prolonged grief disorder (PGD) symptoms who had lost a close person to suicide were randomly allocated either to the intervention group (IG) or waitlist-control group (WCG). The 5-week intervention comprised ten writing assignments in three phases: self-confrontation, cognitive restructuring, and social sharing. Symptoms of PGD, common grief reactions after suicide, depression, and general psychopathology were assessed at pre-, post-test and follow-up. Results: Between-group effect sizes were large for the improvement of PGD symptoms in treatment completers (dppc2 = 1.03) and the intent-to-treat analysis (dppc2 = 0.97). Common grief reactions after suicide and depressive symptoms also decreased in the IG compared to the WCG (moderate to large effects). The results are stable over time. Only for general psychopathology, there was no significant time by group interaction effect found. Conclusions: The ICBGT represents an effective treatment approach for people suffering from PGD symptoms after bereavement by suicide. Considering the effect sizes, the small treatment dose, duration, and the stability of the results, the ICBGT constitutes an appropriate alternative to face-to-face grief interventions.

Antecedentes: La pérdida de un ser querido por suicidio puede ser un evento traumático asociado con el duelo prolongado y el malestar psicológico.Objetivo: Este estudio examinó la eficacia de una terapia cognitivo conductual de duelo basada en el internet (ICBGT en su sigla en inglés), específicamente para las personas en duelo por suicidio.Métodos: En un ensayo controlado aleatorizado, 58 participantes con síntomas de trastorno de duelo prolongado (PGD en su sigla en inglés) que han perdido una persona cercana por suicidio fueron asignados al grupo de intervención (IG en su sigla en inglés) o grupo de control de lista de espera (WCG en su sigla en inglés). La intervención de 5 semanas incluye diez tareas escritas en tres etapas: auto-confrontación, reestructuración cognitiva, y compartir social. Fueron evaluados antes y después de la intervención y al seguimiento, los síntomas de PGD, reacciones de duelo comunes luego de un suicidio, depresión, y psicopatología general.Resultados: Los tamaños de los efectos entre los grupos fueron grandes para la mejoría de los síntomas de PGD en quienes completaron el tratamiento (dppc2=1.03) y el análisis del intento-de-tratar (dppc2=0.97). Las reacciones de duelo comunes luego de suicidio y los síntomas depresivos también disminuyeron en IG en comparación con WCG (efectos moderados a grandes). Los resultados fueron estables a lo largo del tiempo. Solo en psicopatología general no se encontró un efecto significativo de tiempo por grupo.Conclusiones: ICBGT representa una forma de tratamiento efectiva para las personas que sufren de síntomas PGD luego de una pérdida por suicidio. Considerando los tamaños de los efectos, la dosis pequeña de tratamiento, la duración, y la estabilidad de los resultados, ICBGT constituye una alternativa apropiada para las intervenciones en duelo presenciales.

Sweetness Perception is not Involved in the Regulation of Blood Glucose after Oral Application of Sucrose and Glucose Solutions in Healthy Male Subjects.

SCOPE: This study investigates the effect of the sweetness of a sucrose versus an isocaloric glucose solution in dietary concentrations on blood glucose regulation by adjusting the sweetness level using the sweet taste inhibitor lactisole. METHODS AND RESULTS: A total of 27 healthy males participated in this randomized, crossover study with four treatments: 10% glucose, 10% sucrose, 10% sucrose + 60 ppm lactisole, and 10% glucose + 60 ppm lactisole. Plasma glucose, insulin, glucagon-like peptide 1, and glucagon levels are measured at baseline and 15, 30, 60, 90, and 120 min after beverage consumption. Test subjects rated the sucrose solution to be sweeter than the isocaloric glucose solution, whereas no difference in sweetness is reported after addition of lactisole to the sucrose solution. Administration of the less sweet glucose solution versus sucrose led to higher blood glucose levels after 30 min, as reflected by a lower ΔAUC for sucrose (1072 ± 136) than for glucose (1567 ± 231). Application of lactisole leads to no differences in glucose, insulin, or glucagon responses induced by sucrose or glucose. CONCLUSION: The results indicate that the structure of the carbohydrate has a stronger impact on the regulation of blood glucose levels than the perceived sweetness.

Anxiety and depression in patients with Barrett's esophagus: estimates of disorder rates and associations with symptom load and treatment-seeking.

BACKGROUND: Patients with Barrett's esophagus (BE) may experience psychological burden from living with a chronic medical condition, which has been identified as the most important risk factor for esophageal adenocarcinoma. The aim of this study was to estimate rates of depression and anxiety in a large sample of patients with BE. METHODS: A total of 794 patients with endoscopically and histologically confirmed diagnosis of BE completed validated screening instruments for depression (Patient Health Questionnaire-9) and anxiety (Generalized Anxiety Disorder-7). Screening rates in the study sample were compared to general population estimates. Multivariable regression analyses were used to model associations between outcome variables and respondents' sociodemographic characteristics, BE-related symptom load and incidence of inpatient treatment due to BE in the last 12 months. RESULTS: Rates of positive screens were 14.2% for depression and 9.9% for anxiety. For several age by sex subgroups, rates of depression and anxiety were about three to five times higher in the study sample than in the general population. BE-related reflux and pain symptoms showed strong associations with higher levels of depressive and anxiety symptoms, while the effect of treatment was small. CONCLUSION: Study results indicate that a relevant proportion of patients with BE is at an increased risk for depression and anxiety, compared to general population controls. Lacking information on patients' disease characteristics limited generalizability of results.

Sweet Taste Antagonist Lactisole Administered in Combination with Sucrose, But Not Glucose, Increases Energy Intake and Decreases Peripheral Serotonin in Male Subjects.

Knowledge regarding the involvement of sweetness perception on energy intake is scarce. Here, the impact of glucose and sucrose sweetness, beyond their caloric load, on subsequent food intake and biomarkers of satiation was evaluated by co-administration of the sweet taste receptor inhibitor lactisole. A total of 27 healthy, male subjects received solutions of either 10% glucose w/o 60 ppm lactisole or 10% sucrose w/o 60 ppm lactisole. Subsequent food intake from a standardized breakfast was evaluated 2 h after receiving the respective test solution. Changes in postprandial plasma concentrations of cholecystokinin, ghrelin, and serotonin were determined over a period of 120 min, as was the body temperature. Administration of lactisole to the sucrose solution increased the energy intake from the subsequent standardized breakfast by 12.9 ± 5.8% (p = 0.04), led to a decreased Δ AUC of the body core temperature by 46 ± 20% (p = 0.01), and time-dependently reduced Δ serotonin plasma concentrations (-16.9 ± 6.06 ng/mL vs. -0.56 ± 3.7 ng/mL after sucrose administration, p = 0.03). The present study shows that lactisole increases energy intake and decreases plasma serotonin concentrations as well as body core temperature induced by sucrose, but not glucose. This finding may be associated with the different binding affinities of sucrose and glucose to the sweet taste receptor.

Assessing prolonged grief disorder: A systematic review of assessment instruments.

BACKGROUND: Grief reactions that become abnormally persistent and cause significant impairment in functioning have been introduced as new diagnostic entities within the classification systems DSM-5 and ICD-11 termed persistent complex bereavement disorder (PCBDDSM-5) and prolonged grief disorder (PGDICD-11), respectively. In order to assess these conditions, reliable and valid assessment instruments are indispensable. This systematic review examines available assessment tools for disordered grief, reviews their psychometric properties and assesses the extent to which they reflect the diagnostic entities. METHODS: A systematic search of PubMed, PsycINFO and Web of Science databases was conducted. English language articles describing either the development of a measure for assessing PGD in adults or the validation of such a measure were included. RESULTS: Overall 2215 publications were screened, 29 of which met the eligibility criteria. Three of the eleven described assessment tools are structured clinical interviews, one tool is a carer-based assessment and the remaining tools are self-report questionnaires. Most instruments demonstrate excellent or good reliability and validity. No tool assesses the current diagnostic criteria for PGDICD-11 fully. While three tools cover all diagnostic criteria for PCBDDSM-5, only one (TGI-SR) provides an adequate, empirically tested diagnostic algorithm. LIMITATIONS: The inclusion of only English-language publications may have led to omission of relevant measurement tools and/or validation studies in different languages. CONCLUSIONS: The newly released ICD-11 criteria for PGD could serve as a gold standard for diagnosis and build a foundation for the development of more precise assessment tools. Recommendations for clinical practice and future research are provided.

Impact of caregiver burden on mental health in bereaved caregivers of cancer patients: A systematic review.

OBJECTIVE: Although caregiver burden may continue to influence the mental health of cancer patients' caregivers long after bereavement, few studies have examined this issue. METHODS: A systematic review was conducted to provide a summary of (1) operationalizations of caregiver burden used in this field and (2) the effect of caregiver burden on postbereavement mental health of adult caregivers of cancer patients. A systematic search of the electronic databases PubMed, Web of Science, and PsycINFO was conducted across empirical studies published in a peer-reviewed journal up until April 2017. RESULTS: Caregiver burden was rarely defined, and it was operationalized in multiple and diverging ways. The 20 included papers present varying results but generally indicate that caregiver burden (especially emotional) has an adverse effect on postbereavement mental health. CONCLUSIONS: In future studies, researchers seeking to ascertain which aspects of caregiver burden may prove an appropriate target for prevention and intervention should first use a precise operational definition of the concept.
