RESUMO

BACKGROUND: Magnetic resonance imaging (MRI) studies on major depressive disorder (MDD) have predominantly found short-term electroconvulsive therapy (ECT)-related gray matter volume (GMV) increases, but research on the long-term stability of such changes is missing. Our aim was to investigate long-term GMV changes over a 2-year period after ECT administration and their associations with clinical outcome. METHODS: In this nonrandomized longitudinal study, patients with MDD undergoing ECT (n = 17) are assessed three times by structural MRI: Before ECT (t0), after ECT (t1) and 2 years later (t2). A healthy (n = 21) and MDD non-ECT (n = 33) control group are also measured three times within an equivalent time interval. A 3(group) × 3(time) ANOVA on whole-brain level and correlation analyses with clinical outcome variables is performed. RESULTS: Analyses yield a significant group × time interaction (pFWE < 0.001) resulting from significant volume increases from t0 to t1 and decreases from t1 to t2 in the ECT group, e.g., in limbic areas. There are no effects of time in both control groups. Volume increases from t0 to t1 correlate with immediate and delayed symptom increase, while volume decreases from t1 to t2 correlate with long-term depressive outcome (all p ⩽ 0.049). CONCLUSIONS: Volume increases induced by ECT appear to be a transient phenomenon as volume strongly decreased 2 years after ECT. Short-term volume increases are associated with less symptom improvement suggesting that the antidepressant effect of ECT is not due to volume changes. Larger volume decreases are associated with poorer long-term outcome highlighting the interplay between disease progression and structural changes.

RESUMO

BACKGROUND: Early career scientists (ECS) are agents of change and driving forces in the promotion of mental health. The German Center for Mental Health (DZPG) is a powerful initiative to guide and support careers in the field of mental health. OBJECTIVE: The DZPG aims to make investments to educate, engage, excite, and empower ECS in an interdisciplinary and interinstitutional scientific community. STRUCTURES, TOPICS AND INITIATIVES: To achieve this, the ECS Board at the DZPG plays a central role and consists of 18 elected ECS representatives. The ECS culture gives members the right of voice and embraces bottom-to-top ideas and acknowledges autonomy and co-determination. The DZPG academy was developed to facilitate communication and networking and encourage collaboration among ECS members. The DZPG also navigates several key issues, such as equality, diversity, inclusion, family friendliness and work-life balance, which are essential for a functioning research landscape. The DZPG also extends opportunities to ECS to develop skills and competencies that are essential for contemporary ECS. It complements nationwide support for ECS with funding opportunities, mental health support at work, careers advice and guidance activities. Importantly, the ECS Board is committed to patient and public involvement and engagement, scientific communication and knowledge transfer to multiple settings. CONCLUSION: The DZPG will contribute to fostering ECS training programs for student and academic exchanges, collaborative research, and pooling of resources to acquire grants and scholarships. It will also support the establishment of hubs for ECS networks and promote the expansion of international competence of ECS in Germany.

RESUMO

OBJECTIVE: To examine reactive and regulative temperament in patients with compulsive buying (CB) by means of self-report measures and performance-based tasks and to explore the relationship between both measurement approaches. METHOD: The study included 31 treatment-seeking patients with CB (25 women, 6 men) and an age and gender matched non-clinical control group without CB (CG). All participants answered the Compulsive Buying Scale (CBS). Reactive temperament was assessed using the Behavioral Inhibition System/Behavioral Activation System Scales (BIS/BAS) and the Iowa Gambling Task (IGT). Regulative temperament was measured using the Effortful Control subscale of the Adult Temperament Questionnaire (ATQ-EC) and a computerized version of the Stroop Task. To control the results for depression, the Patient Health Questionnaire-Depression Scale (PHQ-9) was administered. RESULTS: Crude group comparisons revealed higher BIS and BAS scores, poorer IGT performance and lower ATQ-EC scores in the CB-group compared to the CG. The groups did not differ in their performance on the Stroop task. After controlling for depressive symptoms that were significantly higher in the CB-group, only the group differences in BAS reactivity remained significant. No significant associations were found between questionnaires and performance-based tasks. CONCLUSION: Overall, the findings indicate that CB in the present clinical sample of treatment-seeking patients was mainly associated with higher approach tendencies and more depressive symptoms. The lacking correlation between self-reports and performance-based tasks is in line with prior research and suggests that both methodologies tap into different aspects of temperament.

RESUMO

Introduction: As a source of audio-visual stimulation, movies expose people to various emotions. Interestingly, several genres are characterized by negative emotional content. Albeit theoretical approaches exist, little is known about preferences for specific movie genres and the neuronal processing of negative emotions. Methods: We investigated associations between movie genre preference and limbic and reward-related brain reactivity to close this gap by employing an fMRI paradigm with negative emotional faces in 257 healthy participants. We compared the functional activity of the amygdala and the nucleus accumbens (NAcc) between individuals with a preference for a particular movie genre and those without such preference. Results and discussion: Amygdala activation was relatively higher in individuals with action movie preference (p TFCE-FWE = 0.013). Comedy genre preference was associated with increased amygdala (p TFCE-FWE = 0.038) and NAcc activity (p TFCE-FWE = 0.011). In contrast, crime/thriller preference (amygdala: p TFCE-FWE ≤ 0.010, NAcc: p TFCE-FWE = 0.036), as well as documentary preference, was linked to the decreased amygdala (p TFCE-FWE = 0.012) and NAcc activity (p TFCE-FWE = 0.015). The study revealed associations between participants' genre preferences and brain reactivity to negative affective stimuli. Interestingly, preferences for genres with similar emotion profiles (action, crime/thriller) were associated with oppositely directed neural activity. Potential links between brain reactivity and susceptibility to different movie-related gratifications are discussed.

RESUMO

BACKGROUND AND AIM: Even though health-related quality of life (HRQOL) is considered an important component of bariatric surgery outcome, there is a lack of HRQOL measures relevant for preoperative and postoperative patients. The objective of the current study was to develop a new instrument assessing HRQOL prior to and following bariatric surgery, entitled Quality of Life for Obesity Surgery (QOLOS) Questionnaire. METHODS: Topics for the QOLOS were initially generated via open-ended interviews and focus groups with 19 postoperative bariatric surgery patients. Qualitative analysis resulted in 250 items, which were rated by patients (n = 101) and experts (n = 69) in terms of their importance. A total of 120 items were retained for further evaluation and administered to 220 preoperative patients and 219 postoperative patients. They also completed a battery of other assessments to analyze issues of construct validity. RESULTS: Analyses resulted in a 36-item section 1 QOLOS form targeting both preoperative and postoperative aspects across seven domains (eating disturbances, physical functioning, body satisfaction, family support, social discrimination, positive activities, partnership) and a 20-item section 2 QOLOS form focusing on postoperative concerns only (domains: excess skin, eating adjustment, dumping, satisfaction with surgery). Subscales of both sections showed acceptable to excellent internal consistency (Cronbach's α 0.72 to 0.95) and good convergent and discriminant validity. CONCLUSION: The QOLOS represents a reliable and valid instrument to assess HRQOL in preoperative and postoperative patients. Future studies should test the questionnaire in larger samples consisting of patients undergoing different types of surgery.

RESUMO

BACKGROUND: Internalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS). The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS. METHODS: The WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI) was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted. RESULTS: Internal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem. CONCLUSIONS: Findings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight-related and psychosocial outcomes.
