  abstract  = {The Brief Symptom Inventory (BSI)-18 is a widely-used tool to assess changes in general distress in patients despite an ongoing debate about its factorial structure and lack of evidence for longitudinal measurement invariance (LMI). We investigated BSI-18 scores from 1,081 patients from an outpatient clinic collected after the 2nd, 6th, 10th, 18th, and 26th therapy session. Confirmatory factor analysis (CFA) was used to compare models comprising one, three, and four latent dimensions that were proposed in the literature. LMI was investigated using a series of model comparisons, based on chi-square tests, effect sizes, and changes in comparative fit index (CFI). Psychological distress diminished over the course of therapy. A four-factor structure (depression, somatic symptoms, generalized anxiety, and panic) showed the best fit to the data at all measurement occasions. The series of model comparisons showed that constraining parameters to be equal across time resulted in very small decreases in model fit that did not exceed the cutoff for the assumption of measurement in variance. Our results show that the BSI-18 is best conceptualized as a four-dimensional tool that exhibits strict longitudinal measurement invariance. Clinicians and applied researchers do not have to be concerned about the interpretation of mean differences over time.},

  abstract  = {Positive factors are increasingly recognized in the field of psychology, however, few studies have investigated the longitudinal measurement invariance (LMI) and reciprocal associations of positive core constructs, such as happiness, life satisfaction and positive mental health. This study evaluated the LMI of these constructs over four years in a Chinese Student Sample (n = 4400) using the Subjective Happiness Scale (SHS), the Satisfaction with Life Scale (SWLS) and the Positive Mental Health Scale (PMH-scale). The longitudinal reciprocal associations of the constructs were examined within a random intercept cross-lagged panel model (RI-CLPM). The results show that the SHS, SWLS and PMH-scale are measurement invariant over time and that the constructs are positively inter-related, but show different reciprocal patterns over time.},

  abstract  = {Hintergrund: Wenn Kinder Schmerzen haben, reagieren Eltern kognitiv-affektiv und verhaltensbezogen. Dysfunktionale Reaktionen wie elterliches Katastrophisieren k{\"o}nnen zur Chronifizierung kindlicher Schmerzen beitragen. Ziel der Arbeit: Ziele der Online-Studie sind (1) die erstmalige psychometrische {\"U}berpr{\"u}fung existierender Frageb{\"o}gen zu kognitiv-affektiven (Pain Catastrophizing Scale for Parents; PCS-P) und verhaltensbezogenen Reaktionen (Inventar zum schmerzbezogenen Elternverhalten; ISEV-E) an 105 schmerzfreien Eltern, (2) der Vergleich der Reaktionen mit existierenden (inter-)nationalen klinischen und schmerzfreien Samples sowie mit 80 Eltern mit selbstberichteten chronischen Schmerzen. Methode: Die teilnehmenden Eltern machten per Online-Fragebogen Angaben zu ihren elterlichen Reaktionen auf kindlichen Schmerz. Ergebnisse: Die Faktoren des ISEV-E konnten nicht best{\"a}tigt werden; die Faktorenstruktur des PCS-P war replizierbar. Das elterliche Katastrophisieren der schmerzfreien Eltern war geringer als in klinischen Samples. Unterschiede zwischen schmerzfreien Eltern und Eltern mit selbstberichteten chronischen Schmerzen aus der Allgemeinbev{\"o}lkerung zeigten sich nicht. Diskussion: Die Ergebnisse bieten eine Basis zur Einordnung des elterlichen Katastrophisierens, um Risikogruppen mit starker Katastrophisierungsneigung fr{\"u}hzeitig zu identifizieren.},

  abstract  = {Background: Chemotherapy-induced Peripheral Neuropathy (CIPN) of large-fibers affects up to 20\% of survivors of pediatric acute lymphoblastic leukemia (ALL). We aimed to describe small-fiber toxicity and pain sensitization in this group. Methods: In a cross-sectional, bicentric study we assessed 46 survivors of pediatric ALL (Mean age: 5.7 ± 3.5 years at diagnosis, median 2.5 years after therapy; males: 28). Inclusion criteria: ≥6 years of age, ≥3 months after last administration of Vincristine, and cumulative dose of Vincristine 12 mg/m2. We used a reduced version of the Pediatric-modified Total Neuropathy Score (Ped-mTNS) as bedside test and Quantitative Sensory Testing (QST) for assessment of small- and large-fiber neuropathy as well as pain sensitization. We employed Nerve Conduction Studies (NCS) as the most accurate tool for detecting large-fiber neuropathy. Results: Fifteen survivors (33\%) had abnormal rPed-mTNS values (≥4 points) and 5 survivors (11\%) reported pain. In QST, the survivor group showed significant (p < 0.001) inferior large-fiber function and pain sensitization when compared to healthy matched peers. We identified deficits of vibration in 33 (72\%) and tactile hypoesthesia in 29 (63\%), hyperalgesia to blunt pressure in 19 (41\%), increased mechanical pain sensitivity in 12 (26\%) and allodynia in 16 (35\%) of 46 survivors. Only 7 survivors (15\%) had pathologic NCS. Conclusion: QST is a sensitive tool that revealed signs of large-fiber neuropathy in two thirds, small-fiber neuropathy and pain sensitization in one third of survivors. Prospective studies using QST in pediatric oncology may help to elucidate the pathophysiology of small-fiber neuropathy and pain sensitization as well as their relevance for quality of survival.},

  abstract  = {Objective: The German version of the Social Phobia and Anxiety Inventory (SPAI-G) is avalidated measure for the detection of social anxiety disorder (SAD). The aim of the presentstudy was to develop optimal cut points (OC) for remission and response to treatment for theSPAI-G. Methods: We used Receiver Operating Characteristic methods and bootstrapping to analysethe data of 359 patients after psychotherapeutic treatment. OCs where defined as the cut pointswith the highest sensitivity and specificity after bootstrapping. Results: For remission, an OC of 2.79 was found, and for response, a change in score frompre- to posttreatment by 11\% yielded best results. Conclusions: The OC we identified for remission may be used to improve the diagnostic utilityof the SPAI-G. However, the cut point for response achieved only borderline-acceptable levelsof sensitivity and specificity, calling into doubt their utility in clinical and research setting.},
