Mothers' and Fathers' Perspectives on the Causes of Their Child's Disorder.

BACKGROUND: Parental beliefs about the cause of their child's illness are thought to affect parents' help-seeking behaviors, treatment decisions, and the child's health outcomes. Yet, research on parental beliefs about disease causation is still scarce. While a small number of studies assesses parental cause attributions for singular disorders (e.g., neurodevelopmental disorders), no study has compared disorders with differing physical versus mental conditions or with mixed comorbidities in children and adolescents or their caregivers. Furthermore, most pediatric research suffers from a lack of data on fathers. OBJECTIVE: Hence, the objective of the current study was to test for possible differences in mothers' and fathers' perceptions about the etiology of their child's illness. METHODS: Forty-two parent couples (overall N = 84) whose child had been diagnosed either with Attention Deficit Hyperactivity-Disorder (ADHD) or Autism Spectrum Disorder (ASD) (category "neurodevelopmental disorder") or with a primary physical illness and a comorbid mental disorder, e.g. depression (category "psychosomatic disorder") were asked to rate possible causes of their child's illness using a modified version of the revised Illness Perception Questionnaire (IPQ) Cause scale. RESULTS: A two-way ANOVA showed that psychosomatic disorders were significantly more strongly attributed to be caused by medical and environmental stressors than neurodevelopmental disorders. A significant parent × illness category interaction revealed that this effect was more pronounced in fathers. CONCLUSIONS: By providing first insights into parental beliefs about the etiology of their children's neurodevelopmental versus psychosomatic disorders, this study paves ground for future research and tailored counseling of affected families.

Emotion regulation and mental well-being before and six months after bariatric surgery.

PURPOSE: According to the current state of research, mental health improves due to bariatric surgery. However, improvements in weight and psychosocial aspects often show a gradual decline with time. As emotion regulation (ER) appears to be a key variable in the successful outcome of weight loss treatments, the present study aimed at investigating ER-strategies applied by bariatric surgery candidates pre- and post-surgery and examining interactions between ER, depressive symptoms, health-related quality of life (HrQoL), and post-surgical weight loss. METHODS: Prior to and 6 months after bariatric surgery, 45 patients (76% women) completed self-report questionnaires assessing depressive symptoms (Beck Depression Inventory-II), HrQoL (Short Form-36 Health Survey), and ER-strategies (Emotion Regulation Inventory for Negative Emotions). RESULTS: Six months post-surgery, the patients reported significant improvements in depressive symptomatology, HrQoL, and satisfaction with ER compared to pre-surgery. Groups differing in their course of ER-satisfaction also differed in psychosocial dimensions pre- to post-surgery, increased satisfaction being related to less impairment and enhanced communication of negative emotions as a form of an adaptive regulation. Patients with higher weight loss applied the strategy of controlled expression more frequently post-surgery than pre-surgery and compared to patients with lower weight loss. CONCLUSIONS: Postoperative weight loss leads to improvements in ER-satisfaction and mental well-being. As satisfaction with ER seems to be associated with less impaired mental well-being among bariatric surgery candidates, presumably even more positive psychosocial outcomes could be obtained post-surgery by implementing trainings explicitly encouraging the use of adaptive ER-strategies.

No influence of 5-HTTLPR gene polymorphism on migraine symptomatology, comorbid depression, and chronification.

BACKGROUND: The serotonergic system is thought to play an important role for mediating susceptibility to migraine and depression, which is frequently found comorbid in migraine. The functional polymorphism in the serotonin transporter gene linked polymorphic region (5-HTTLPR/SLC6A4) was previously associated with attack frequency and, thus, possibly with chronification. OBJECTIVE: We hypothesized that patients with the "s" allele have higher attack frequency and, paralleling results in depression research, higher scores of depression. METHODS: Genetic analysis of the SLC6A4 44 bp insertion/deletion polymorphism (5-HTTLPR) was performed in 293 patients with migraine with and without aura. Self-rating questionnaires were used for assessment of depression. RESULTS: Multinomial logistic regression analysis found no evidence for association of the 5-HTTLPR polymorphism with either depression or migraine attack frequency. CONCLUSION: We were not able to demonstrate any influence of the serotonin transporter 5-HTTLPR polymorphism on migraine phenomenology (attack frequency or comorbid depression), thereby excluding this variant to be a common genetic denominator for chronic migraine and depression.

Altered reward processing in the nucleus accumbens and mesial prefrontal cortex of patients with posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) is known to be associated with altered medial prefrontal activation in response to threatening stimuli and with behavioural deficits in prefrontal functions such as working memory and attention. Given the importance of these areas and processes for decision-making, this functional magnetic resonance imaging study investigated whether decision-making is altered in patients with PTSD. In particular, the neural response to gain and loss feedback was evaluated in a decision-making task in which subjects could maximise their number of points total by learning a particular response pattern. Behaviourally, controls learned the correct response pattern faster than patients. Functionally, patients and controls differed in their neural response to gains, but not in their response to losses. During the processing of gains in the late phase of learning, PTSD patients as compared to controls showed lower activation in the nucleus accumbens and the mesial PFC, critical structures in the reward pathway. This reduced activation was not due to different rates of learning, since it was similarly present in patients with unimpaired learning performance. These findings suggest that positive outcome information lost its salience for patients with PTSD. This may reflect decreasing motivation as the task progressed.
