The Development and Validation of the First German Open Scale of Social Information Processing.

INTRODUCTION: This study introduces the first German Open Scale of Social Information Processing (GOSSIP) and evaluates its psychometric properties. Even though social information processing (SIP) and its important role in developmental psychopathology is a rising field of interest, model-based standardized assessment tools are still scarce. METHODS: GOSSIP was developed to assess SI processes in boys and girls aged eight to 21 years. First, 61 vignettes (combinations of pictures and short written descriptions of the situation depicted) were evaluated by an expert group and piloted with 48 healthy participants (aged 8-21). The best-rated vignettes were then implemented in a Web-based application. 191 participants completed GOSSIP. Of those, 76 answered additional questionnaires to assess their social skills and psychopathology. Internal consistencies for the emotional and cognitive GOSSIP scales were determined. Latent profile analysis (LPA) was used to identify subgroups of children and adolescents characterized by specific SIP profiles (i.e., patterns of emotional, cognitive, and behavioral responses to the GOSSIP). Furthermore, the external validity of the participants' attribution tendencies in GOSSIP was evaluated in real life by smartphone-based Ecological Momentary Assessments (EMA). RESULTS: The internal consistencies for the emotional and cognitive scales (angry, ashamed, physical aggression, pro-social response, revenge, and outcome expectancy) were good to excellent. The scales of hostile interpretation, relation aggression, sadness, and exclusion showed borderline/acceptable internal consistency. Correlation analysis confirmed convergent validity with self-reported social skills and external validity with ratings of aggressive and pro-social behaviors. The LPA revealed three profiles as the best fit of the data. The first group is named "aggressors," the second "social-emotional group," and a third named "ashamed-internalizing group." However, no significant association was found between the attribution tendencies derived from GOSSIP and EMA data. DISCUSSION/CONCLUSION: GOSSIP is the first model-based German Web-based assessment for several SIP mechanisms that showed overall adequate psychometric properties. GOSSIP can be used to classify individuals into SIP profiles that differ in terms of their cognitive and emotional response tendencies and therefore could contribute to the development of targeted interventions. Integrating assessments of emotional responses into GOSSIP revealed an important role of "shame" in SIP and the development of psychopathology. Furthermore, the lack of external validity between GOSSIP and EMA calls into question how attribution tendencies are best assessed in future studies.

Gender and Age Differences in ADHD Symptoms and Co-occurring Depression and Anxiety Symptoms Among Children and Adolescents in the BELLA Study.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most diagnosed neurodevelopmental disorders of childhood. Current studies addressing gender and age differences in ADHD are lacking. The present study aims to fill this research gap by dimensionally evaluating gender and age differences in ADHD symptoms, as measured by a DSM-5-based parent rating scale, in children and adolescents who participated in the two-year follow-up of the community-based BELLA study (n = 1326). Associations between ADHD symptoms and depression symptoms and anxiety symptoms were also examined. Multiple linear regressions revealed significant associations between gender and all ADHD symptoms. Age was significantly associated with hyperactive/impulsive symptoms. Additional multiple linear regressions demonstrated significant positive associations between depression and anxiety symptoms and ADHD symptoms. Further, female gender was found to be positively associated with both depression and anxiety symptoms. These findings may suggest a need for more gender-specific approaches to ADHD diagnosis and treatment, as well as more research into the intersections of ADHD and depression and anxiety symptoms in children and adolescents.

Psychometric evaluation of the Positive Mental Health (PMH) scale using item response theory.

BACKGROUND: The investigation of patient-reported outcomes and psycho-oncological interventions mainly focuses on psychological distress or psychopathology. However, the recognition of the equal importance of positive mental health (PMH) has increased lately. The PMH-scale is a brief questionnaire allowing to assess well-being in individuals in the general population and in patients. Previous studies evaluated the psychometric properties of the PMH-scale using classical test theory (CTT). This study is the first to investigate the PMH-scale in patients with cancer using item analysis according to the Rasch model. METHODS: In total, N = 357 cancer patients participated in the study. A Rasch analysis of the PMH-scale was conducted including testing of unidimensionality, local independence, homogeneity and differential item functioning (DIF) with regard to age, gender, type of cancer, the presence of metastases, psycho-oncological support, and duration of disease. Additionally, the ordering of the item thresholds as well as the targeting of the scale were investigated. RESULTS: After excluding one misfitting item and accounting for local dependence by forming superitems, a satisfactory overall fit to the Rasch model was established (χ2 = 30.34, p = 0.21). The new PMH-8 scale proved to be unidimensional, and homogeneity of the scale could be inferred. All items showed ordered thresholds, there was no further item misfit. DIF was found for age, but as the impact of DIF was not substantial, no adjustment related to the age-DIF had to be made. The Person Separation Index (PSI = 0.89) was excellent, indicating excellent discriminatory power between different levels of positive mental health. Overall, the targeting of the PMH-8 was good for the majority of the present sample. However, at both ends of the scale item thresholds are missing as indicated by a slight floor effect (1.4%) and a considerable ceiling effect (9.8%). CONCLUSIONS: Overall, the results of the analysis according to the Rasch model support the use of the revised PMH-scale in a psycho-oncological context.

Development of the German social attitude barriers and facilitators to participation-scales: an analysis according to the Rasch model.

BACKGROUND: Social attitudes experienced by people with disabilities can strongly impact upon their health and quality of life. The extent to which social attitude measurement transcends specific cultures is unknown. Thus, the aim of the study was to develop German item banks to assess social attitude barriers and facilitators to participation and compare the construct definition with that developed in the United States. METHODS: The American version of the two item banks assessing social attitudes that act as barriers and facilitators in persons with disabilities was translated into German and culturally adapted. The sample consisted of 410 in- and outpatients treated for spinal diseases at a German University Hospital. The psychometric properties of the resulting 53 items-item pool were evaluated using Rasch analysis. A special focus was placed on the investigation of unidimensionality, local independence, differential item functioning (DIF) and targeting. To evaluate convergent and divergent validity correlations with perceived social support, depression and pain interference were calculated. RESULTS: Unlike the American version, both the barriers and facilitators item banks had to be divided into two subscales assessing attitudes that individuals with disabilities experience as being directed towards them (individual perception) or attitudes that respondents experience as being directed towards people with disabilities as a social group (societal perception). Four unidimensional scales were constructed. Fit to the Rasch model required item deletion and forming testlets to account for extensive local dependence. There was no evidence of DIF with regard to gender or age. Targeting of the subscales was moderate to good. CONCLUSIONS: Results support a distinction between social attitudes at the individual and societal level, allowing a more specific assessment than is possible when this distinction is ignored.

An item analysis according to the Rasch model of the German 12-item WHO Disability Assessment Schedule (WHODAS 2.0).

PURPOSE: The World Health Organization Disability Assessent Schedule 2.0 (WHODAS 2.0) assesses disability in individuals irrespective of their health condition. Previous studies validated the usefulness of the WHODAS 2.0 using classical test theory. This study is the first investigating the psychometric properties of the 12-items WHODAS 2.0 in patients with cancer using item analysis according to the Rasch model. METHODS: In total, 350 cancer patients participated in the study. Rasch analysis of the 12-items version of the WHODAS 2.0 was conducted and included testing unidimensionality, local independence, and testing for differential item functioning (DIF) with regard to age, gender, type of cancer, presence of metastases, psycho-oncological support, and duration of disease. RESULTS: After accounting for local dependence, which was mainly found across items of the same WHODAS domain, satisfactory overall fit to the Rasch model was established (χ2 = 36.14, p = 0.07) with good reliability (PSI = 0.82) and unidimensionality of the scale. DIF was found for gender (testlet 'Life activities') and age (testlet 'Getting around/Self-care'), but the size of DIF was not substantial. CONCLUSION: Overall, the analysis results according to the Rasch model support the use of the WHODAS 2.0 12-item version as a measure of disability in cancer patients.

Elated or sad mood induction affects the attention of patients with a bipolar disorder less than that of patients with a depressive disorder.

Introduction: The role of acute mood states as mediating factors in cognitive impairment in patients with mania or depression is not sufficiently clear. Similarly, the extent to which cognitive impairment is trait or state-specific remains an open question. Therefore, the aim of this study was to investigate the effect of a mood-induction on attention in patients with an affective disorder.Methods: Twenty-two depressed bipolar patients, 10 manic bipolar patients, 17 with a depressive episode (MDE), and 24 healthy controls performed the Attention-Network-Test (ANT). In a within-participants design, elated and sad moods were induced by an autobiographic recall and measured on a self-report scale. Subsequently, participants performed the ANT again.Results: The modulating effect of the elated mood induction on attention was small. Only the MDE group displayed moderate improvements in selective attention and tonic alertness. Surprisingly, after the sad mood induction, patients with MDE improved moderately on phasic and tonic alertness. Phasic alertness was also enhanced in patients with mania. Finally, after the mood induction, patients with MDE showed the largest variability in attentional performance.Conclusions: Results showed only small effects of mood induction on attention. This supports the view that attention deficits reflect trait variables.

Calibration of an item bank in 474 orthopedic patients using Rasch analysis for computer-adaptive assessment of anxiety.

OBJECTIVE: To calibrate an item bank of anxiety-related questions for use in orthopedic patients within a computer-adaptive test. DESIGN: This is a psychometric study. SETTING: The sample of orthopedic patients was recruited in two orthopedic rehabilitation clinics in Germany. SUBJECTS: A total of 474 orthopedic rehabilitation patients were recruited for this study. INTERVENTIONS: Not applicable. MAIN MEASURES: The main measure is an adapted version of an existing anxiety item pool for cardiovascular rehabilitation patients. RESULTS: The results of the confirmatory factor analysis and Mokken analysis confirmed a one-factor structure and double monotonicity. An anxiety item bank (48 items) could be developed and calibrated using Rasch analysis. It fitted to the Rasch model with a non-significant item-trait interaction (χ2(203) = 172.59; P = .94) and was free of differential item functioning. Unidimensionality could be verified and the person separation reliability was .96. The category threshold parameters varied between 4.72 and 3.16 (7.88 logits). CONCLUSION: The unidimensional anxiety item bank provides the basis for a computer-adaptive test to assess a wide range of anxiety in rehabilitation patients with orthopedic diseases with very good psychometric characteristics.

Development of a short scale for assessing economic environmental aspects in patients with spinal diseases using Rasch analysis.

BACKGROUND: Economic environmental factors represent important barriers to participation and have deleterious effects on quality of life (QOL) in persons with spinal diseases (SpD). While economic factors are anchored in the International Classification of Functioning, Disability and Health, their influence on QOL and participation from patients' perspectives is an infrequent focus of research. The aim of the present research is to calibrate a culturally adapted Rasch-based questionnaire assessing economic QOL in patients with SpD. METHODS: The 11-items of the German economic-QOL-scale were answered by 325 patients with SpD on a four-point Likert-scale. Fit to the Rasch measurement model was investigated by testing for stochastic ordering of the items, unidimensionality, local independence, and differential item functioning (DIF). RESULTS: After adjusting for local dependency, fit to the Rasch model was achieved with a non-significant item-trait interaction (chi-squaredf = 20 = 34.8, p = 0.021). The person separation reliability equaled 0.88, the scale was free from age- or gender-related DIF, and unidimensionality could be verified. CONCLUSIONS: The Rasch-based German version of the economic-QOL-scale represents a suitable instrument to investigate the influences of economic factors on patients' QOL at a group and individual level. It can be easily applied in research and practice and may be administered quickly in combination with other instruments. The short test duration implies a low test burden for patients and a minimum of time expenditure by clinicians when evaluating the results.

Emotion suppression, not reappraisal, predicts psychotherapy outcome.

OBJECTIVES: The aim of this study was to identify whether trait emotion regulation strategies predict successful or unsuccessful psychotherapy outcomes in cognitive behaviour therapy. METHODS: Three emotion regulation strategies (reappraisal, suppression, and externalizing behaviour) were assessed in 358 in- and outpatients. Patients were then grouped by therapy outcome. Emotion regulation strategies and confounding variables were entered as predictors in multinomial logistic regression analyses. RESULTS: Emotion suppression, but not reappraisal, was found to predict therapy outcomes for in- and outpatients, with patients high in suppression experiencing worse outcomes. Externalizing behaviour was only relevant in inpatient treatment. CONCLUSIONS: High suppression might be detrimental to psychotherapy outcome and should be assessed early on. Further research should investigate the influence of suppression on the mechanisms that facilitate change in psychotherapy.

Neural correlates of positive and negative performance feedback in younger and older adults.

BACKGROUND: Recent studies with younger adults have shown that performance feedback can serve as a reward, and it elicits reward-related brain activations. This study investigated whether performance feedback is processed similarly in younger and older adults and whether there are differential aging effects for positive and negative performance feedback. METHODS: We used event-related fMRI in a choice reaction-time task and provided performance feedback after each trial. RESULTS: Although younger and older adults differed in task-related activation, they showed comparable reward-related activation. Positive performance feedback elicited the strongest striatal and amygdala activation, which was reflected behaviorally in slightly faster reaction times. CONCLUSIONS: These results suggest that performance feedback serves as a reward in both younger and older adults.

Differences in Patient Health Questionnaire and Aachen Depression Item Bank scores between tablet versus paper-and-pencil administration.

PURPOSE: To extend knowledge about measurement equivalence of depression measures assessed by tablet and paper-pencil administration, the present study evaluated the effect of mode of administration (MoA) on scale and item level for the Patient Health Questionnaire (PHQ-9) and the Aachen Depression Item Bank (ADIB) in elderly patients. METHODS: Primary care patients (N = 193, ≥60 years) were assessed following a crossover design in Leipzig, Germany. All participants filled out the PHQ-9 and the ADIB in both MoAs under study. Effects of MoA were analyzed by intra-class correlation, mixed-effects regression, and differential item functioning (DIF). Additionally, detection rates between both MoAs were compared using receiver operating characteristics analysis compared to a diagnostic interview (SCID-I, N = 163). RESULTS: No effect of MoA was found in the PHQ-9 on scale score or item level. Two ADIB items showed DIF according to MoA. In terms of discriminatory power, MoA did not influence detection rates of both instruments. CONCLUSIONS: In summary, our findings suggest that no severe effect of mode of administration on self-report assessments of depression should be expected. It can be concluded that tablets provide a valid way to electronically assess depressive symptoms in elderly patients. Yet changes in item presentation can influence the psychometric properties and require equivalence testing using sophisticated analyses on item level such as DIF.

Interpersonal neural synchrony and mental disorders: unlocking potential pathways for clinical interventions.

Introduction: Interpersonal synchronization involves the alignment of behavioral, affective, physiological, and brain states during social interactions. It facilitates empathy, emotion regulation, and prosocial commitment. Mental disorders characterized by social interaction dysfunction, such as Autism Spectrum Disorder (ASD), Reactive Attachment Disorder (RAD), and Social Anxiety Disorder (SAD), often exhibit atypical synchronization with others across multiple levels. With the introduction of the "second-person" neuroscience perspective, our understanding of interpersonal neural synchronization (INS) has improved, however, so far, it has hardly impacted the development of novel therapeutic interventions. Methods: To evaluate the potential of INS-based treatments for mental disorders, we performed two systematic literature searches identifying studies that directly target INS through neurofeedback (12 publications; 9 independent studies) or brain stimulation techniques (7 studies), following PRISMA guidelines. In addition, we narratively review indirect INS manipulations through behavioral, biofeedback, or hormonal interventions. We discuss the potential of such treatments for ASD, RAD, and SAD and using a systematic database search assess the acceptability of neurofeedback (4 studies) and neurostimulation (4 studies) in patients with social dysfunction. Results: Although behavioral approaches, such as engaging in eye contact or cooperative actions, have been shown to be associated with increased INS, little is known about potential long-term consequences of such interventions. Few proof-of-concept studies have utilized brain stimulation techniques, like transcranial direct current stimulation or INS-based neurofeedback, showing feasibility and preliminary evidence that such interventions can boost behavioral synchrony and social connectedness. Yet, optimal brain stimulation protocols and neurofeedback parameters are still undefined. For ASD, RAD, or SAD, so far no randomized controlled trial has proven the efficacy of direct INS-based intervention techniques, although in general brain stimulation and neurofeedback methods seem to be well accepted in these patient groups. Discussion: Significant work remains to translate INS-based manipulations into effective treatments for social interaction disorders. Future research should focus on mechanistic insights into INS, technological advancements, and rigorous design standards. Furthermore, it will be key to compare interventions directly targeting INS to those targeting other modalities of synchrony as well as to define optimal target dyads and target synchrony states in clinical interventions.

Development and calibration of an item bank for the assessment of activities of daily living in cardiovascular patients using Rasch analysis.

BACKGROUND: To develop and calibrate the activities of daily living item bank (ADLib-cardio) as a prerequisite for a Computer-adaptive test (CAT) for the assessment of ADL in patients with cardiovascular diseases (CVD). METHODS: After pre-testing for relevance and comprehension a pool of 181 ADL items were answered on a five-point Likert scale by 720 CVD patients, who were recruited in fourteen German cardiac rehabilitation centers. To verify that the relationship between the items is due to one factor, a confirmatory factor analysis (CFA) was conducted. A Mokken analysis was computed to examine the double monotonicity (i.e. every item generates an equivalent order of person traits, and every person generates an equivalent order of item difficulties). Finally, a Rasch analysis based on the partial credit model was conducted to test for unidimensionality and to calibrate the item bank. RESULTS: Results of CFA and Mokken analysis confirmed a one factor structure and double monotonicity. In Rasch analysis, merging response categories and removing items with misfit, differential item functioning or local response dependency reduced the ADLib-cardio to 33 items. The ADLib-cardio fitted to the Rasch model with a nonsignificant item-trait interaction (chi-square = 105.42, df = 99; p = 0.31). Person-separation reliability was 0.81 and unidimensionality could be verified. CONCLUSIONS: The ADLib-cardio is the first calibrated, unidimensional item bank that allows for the assessment of ADL in rehabilitation patients with CVD. As such, it provides the basis for the development of a CAT for the assessment of ADL in patients with cardiovascular diseases. Calibrating the ADLib-cardio in other than rehabilitation cardiovascular patient settings would further increase its generalizability.

The negative affect repair questionnaire: factor analysis and psychometric evaluation in three samples.

BACKGROUND: Negative affect and difficulties in its regulation have been connected to several adverse psychological consequences. While several questionnaires exist, it would be important to have a theory-based measure that includes clinically relevant items and shows good psychometric properties in healthy and patient samples. This study aims at developing such a questionnaire, combining the two Gross [1] scales Reappraisal and Suppression with an additional response-focused scale called Externalizing Behavioral Strategies covering clinically relevant items. METHODS: The samples consisted of 684 students (mean age = 23.3, SD = 3.5; 53.6% female) and 369 persons with mixed mental disorders (mean age = 36.0 SD = 14.6; 71.2% female). Items for the questionnaire were derived from existing questionnaires and additional items were formulated based on suggestions by clinical experts. All items start with "When I don't feel well, in order to feel better…". Participants rated how frequently they used each strategy on a 5-point Likert scale. Confirmatory Factor Analyses were conducted to verify the factor structure in two separate student samples and a clinical sample. Group comparisons and correlations with other questionnaires were calculated to ensure validity. RESULTS: After modification, the CFA showed good model fit in all three samples. Reliability scores (Cronbach's α) for the three NARQ scales ranged between .71 and .80. Comparisons between students and persons with mental disorders showed the postulated relationships, as did comparisons between male and female students and persons with or without Borderline Personality Disorder. Correlations with other questionnaires suggest the NARQ's construct validity. CONCLUSIONS: The results indicate that the NARQ is a psychometrically sound and reliable measure with practical use for therapy planning and tracking of treatment outcome across time. We advocate the integration of the new response-focused strategy in the Gross's model of emotion regulation.

Cross-sectional validation of the Rasch-based Depression Screening (DESC) in a mixed sample of patients with mental and somatic diseases.

BACKGROUND: The study aimed to cross-validate the psychometric properties of the two parallel versions of the "Rasch-based Depression Screening (DESC)" in a mixed clinical sample of patients with mental disorders and somatic diseases. Additionally, it was intended to confirm the initially proposed cut-off scores. METHODS: One hundred eleven inpatients from the Departments of Psychiatry (n=50), Cardiology (n=39) and Otorhinolaryngology (n=22) were examined. Accordance to Rasch model assumptions was determined by analyzing item infit and outfit as well as unidimensionality and local independence via residual principal components factor analysis (PCFA). Furthermore, separation, reliability and the targeting were considered. Differential item functioning (DIF) was investigated with regard to gender, age and clinical group. Finally, receiver operating characteristics (ROC) curves analyses were conducted and parallel test reliability was calculated. RESULTS: Item and person separation and reliability were good with separation values being above 2.90 and reliability exceeding being .90. Rasch model fit was good for all items except for the two items "sad" and "hopeless" displaying slight misfit. Targeting was appropriate with a person mean of -1.6 (DESC-I) and -1.5 (DESC-II) reflecting as expected that the two DESC versions were in average to easy for a mixed sample of patients with mental disorders and somatic. PCFA showed unidimensionality and local independence: The Rasch dimension "depression" explained 84.8% (DESC-I) and 82.2% (DESC-II) of the observed variance. No DIF was found. ROC curves confirmed the proposed cut-off score of 12 points. The area under the curve amounted to .91 for both DESC forms. The Youden index was 75.5 for DESC-I and 75.7 for DESC-II. A high parallel test reliability of .94 showed virtual equivalence of both DESC forms. CONCLUSIONS: Results of the present study support the good psychometric properties of both DESC forms in patients with mental disorders and somatic diseases. This study confirmed the cut-off scores that had already been determined in former patient samples. Thus, both DESC forms can be used validly as screening instruments for depression in clinical practice.

Using photographs for rating severity degrees of clinical appearance in research mice enables valid discrimination of extreme but not mild and moderate conditions: A pilot study.

To ensure good animal welfare in laboratory research and in stockbreeding severity ratings of the animals´ wellbeing are essential. The current study investigated how valid raters can evaluate different severity degrees of clinical appearance and how ratings might be influenced by factors other than the severity itself. Ninety-seven people rated the severity degree (none, mild, moderate, or severe) of the clinical appearance of mice seen in eight different images. The images also differed in the perspective in which they had been taken (entire mouse or head only). The raters differed with regard to their experience of working with laboratory animals and were subsequently divided into three groups-beginners, advanced, professionals. Generalisability theory was applied to examine the contribution of the different rater (raters themselves and experience) and image facets (actual degree of severity and perspective) to the overall data variability. The images showing the extreme severity degrees were rated more homogenously and more precisely than were the images showing the intermediate degrees, as compared to the reference scores. The largest source of variance was the actual degree of severity, accounting for 56.6% of the total variance. Considering only the images showing the extreme severity degrees, this percentage rose to 91.6%, accounting almost exclusively for the found variance. In considering only the intermediate severity degrees, the actual degree of severity did not contribute to variance at all. The remaining variance was due to the raters and the interactions between raters, the actual degree of severity and the perspective. The experience of the raters did not account for any variance. Training in the assessment of severity degrees seems necessary to enhance detection of the intermediate degrees of severity, especially when images are used. In addition, good training material should be developed and evaluated to optimise teaching and to minimise wrong assessments.

Mental health and quality of life in children and adolescents during the COVID-19 pandemic: a systematic review of longitudinal studies.

Background: The COVID-19 pandemic has significantly impacted the mental health of children and families, i.e., due to measures like social distancing and remote schooling. While previous research has shown negative effects on mental health and health-related quality of life (HRQoL), most studies have focused on pre-post comparisons in the early pandemic stages. This systematic review aims to examine longitudinal studies to understand the long-term impacts of the pandemic on children and adolescents. Methods: This systematic review adhered to the PRISMA guidelines and was preregistered in the international prospective register of systematic reviews (Record ID: CRD42022336930). We systematically searched PubMed/MEDLINE, Web of Science, PsycINFO, PSYNDEX, and the WHO-COVID-19 database and included studies published up to August 30, 2022. Based on pre-defined eligibility criteria, longitudinal and prospective studies that assessed the mental health or quality of life of children or adolescents (0-19 years) in the general population over a longer time span (at two or more measurement points) during the COVID-19 pandemic were included in the review. The methodological quality of the included studies was assessed using an adapted version of the Effective Public Health Practice Project (EPHPP) checklist. Narrative data synthesis was used to summarize the findings. Results: A total of 5,099 results were obtained from literature searches, with 4,935 excluded during title/abstract screening. After reviewing 163 full-text articles, 24 publications were included in the review. Sample sizes ranged between n = 86 and n = 34,038. The length of the investigated time periods and the number of assessment points, as well as outcomes, varied. The majority of studies were of moderate methodological quality. Mental health outcomes were more frequently studied compared to measures of HRQoL. The findings from these studies mostly suggest that children and adolescents experienced heightened mental health problems, specifically internalizing symptoms like anxiety and depression. Further, there was a decline in their overall HRQoL over the course of the COVID-19 pandemic that did not necessarily subside when lockdowns ended. Conclusion: It is crucial to continue monitoring the mental health and well-being of children and adolescents following the pandemic to identify groups at risks and plan interventions. This should ideally be conducted by large systematic studies, using validated instruments, and encompassing representative samples to obtain reliable and comprehensive insights with the aim of improving youth mental health care.

Poor sleep quality is associated with depressive symptoms in patients with heart disease.

BACKGROUND: Depression in cardiac patients has gained importance due to increased mortality. Although sleep disturbances are a core symptom of depression, the prevalence and patterns of sleep disturbances in heart disease have hardly been examined regarding depression. PURPOSE: This cross-sectional study aims to examine sleep disturbances and depressive symptoms in consecutively admitted cardiac patients and depressed patients. METHODS: Two hundred four inpatients (113 male, 91 female) were examined: 94 cardiac inpatients (mean age 49.3 ± 14.3 years) with different heart diseases and 110 psychiatric inpatients (mean age 41.6 ± 13.0 years) with depressive disorders (DP). A depressive episode according to International Classification of Diseases (ICD)-10 was also diagnosed in 14 of the cardiac patients (DCP). The Pittsburgh Sleep Quality Index (PSQI) and the Beck Depression Inventory (BDI) were used to assess subjective sleep quality and severity of depressive symptoms. RESULTS: Poor sleep quality (PSQI > 5) was reported in all comorbid DCP (PSQI 12.00 ± 3.53, BDI 17.86 ± 4.28), in 60% of the 80 non-DCP (PSQI 5.59 ± 3.73, BDI 4.47 ± 3.07), and in 86.4% of the DP (PSQI 11.76 ± 4.77, BDI 27.11 ± 10.54). The cardiac inpatients showed a significant correlation between increased depressive symptoms and the PSQI components subjective sleep quality (r = 0.40) and daytime dysfunction (r = 0.34). Both sleep components were significant predictors of self-rated depression (R² = 0.404). CONCLUSIONS: Most cardiac patients experience poor sleep quality. Self-reported sleep disturbances in heart disease could serve as predictors of clinical or subclinical comorbid depression outside of a psychiatric setting in cardiology and other fields, and such patients should be referred to consultation-liaison psychiatry or polysomnography where sleep disorders like sleep apnea are suspected.

Psychometric evaluation of the Patient Assessment of Chronic Illness Care instrument using Item analysis according to the Rasch model.

RATIONALE, AIMS AND OBJECTIVES: The Patient Assessment of Chronic Illness Care (PACIC) instrument assesses patient care in alignment with the chronic care model. The aim of the study was to comprehensively validate the PACIC using the Rasch model. A special focus was placed on the investigation of local dependence (LD), differential item functioning (DIF) and targeting. METHOD: This secondary analysis utilized data of 760 patients with a diagnosis of diabetes who had participated in the Swiss CoDiab-VD cohort study. The psychometric properties of the French PACIC-version were evaluated using the Rasch model. DIF was investigated in relation to age, gender, education, year of recruitment into the CoDiab-VD cohort study, type of diabetes and whether patients got an injectable antidiabetic drug or not. RESULTS: The initial analysis of the PACIC revealed poor fit to the Rasch model (χ2 -p < 0.001) with response dependency being the most prominent problem. After combining the items into two testlets (testlet 1: Items 1-11; testlet 2: Items 12-20), good overall model fit was found (χ2 -p = 0.77) as well as good reliability (Person Separation Index = 0.85) and targeting. DIF with regard to whether patients got an injectable antidiabetic drug or not was found for testlet 2. However, the size of this DIF was regarded as not being substantial. CONCLUSION: The PACIC is a well-targeted, reliable unidimensional instrument to assess patient care in alignment with the chronic care model in patients with diabetes. It is free of substantial DIF. The PACIC-20 sum score can hence be used in clinical practice for individual diagnostic. For evaluation purposes like assessment of change or group evaluations, the usage of the interval-scale level person parameters is recommended as it permits using parametric statistical analyses and provides a more accurate picture about the actual amount of change.

When response inhibition is followed by response reengagement: an event-related fMRI study.

In the course of daily living, changing environmental demands often make our actions, once initiated, unnecessary or even inappropriate. Under such circumstances, the ability to inhibit the obsolete action and to update behavior can be of vital importance. Previous lesion and neuroimaging studies have shown that the right prefrontal cortex and the basal ganglia seem to play an important role in the inhibition of already initiated motor responses. The present study was designed to investigate whether the neural activity of inhibitory motor control was altered if the inhibition process was succeeded by an additional process, namely the reengagement into an alternative action. Therefore, cerebral blood oxygenation during performance of a stop-change paradigm was registered in 15 male participants using event-related functional magnetic resonance imaging. Data analysis showed, that during successful and failed stopping and changing (response inhibition and subsequent response reengagement) of initiated motor responses a very similar network was activated including primarily the right inferior frontal cortex (IFC). Besides, stopping-related activation in right IFC was significantly greater for fast inhibitors than for slow ones. Results of the present study thus further underline the important role of right IFC in response inhibition and suggest that the inhibition process functions similarly regardless whether changing task demands require the complete suppression of an already initiated motor response or its suppression and a subsequent response reengagement into an alternative action.
