Additionally, it focused on optimal integration of mental health care into gender-affirming care according to TGD individuals. Both were within the framework of an ongoing investigation at the Zaans Medical Centre. The quantitative data analysis consisted of intake questionnaire data of twenty-five TGD individuals, variables were derived from sections of the intake questionnaire. For the qualitative data analysis, seven semi-structured interviews were held with TGD individuals. The characteristics of TGD individuals consisted of self-reported psychological distress and well-being. Their relationship to requested mental health care intensity was studied through Spearman rank order correlations. The demographics included age, educational level, ethnicity, employment status, experienced income, and gender assigned at birth. Their association with requesting mental health care was explored through chi-square tests. A thematic analysis with semantic approach was performed to analyse the data. No significant correlations were found between demographic variables and mental health care requests at admission. The correlation between self-reported psychological distress and mental health care intensity was χ2 = -.003, p = .987, for self-reported psychological well-being and mental health care intensity χ2 = -.001, p = .997. Thematic analysis of interview data yielded three overarching themes: motives for seeking mental health care, recommendations for integrating mental health services into gender-affirming care, and desirable attributes of mental health care providers. Reasons for refraining from or seeking mental health care included experiencing psychological distress or good psychological well-being, experiences due to gender dysphoria, acceptance of themselves, and experienced lack of support. Suggestions for optimal mental health care integration were better and more provision of (mental) health care and travel distance to mental health care. Qualities of the ideal mental health care professional were having certain character traits such as being accepting and being specialized in TGD. Overall, this research emphasizes the importance of knowledgeability and empathetic and inclusive qualities in mental health care professionals in the treatment of TGD individuals suggesting its importance over mental health care professionals’ gender identity.Show less

Problematic behaviour is often caused by pain and places a heavy burden on both professional and family caregivers. Especially since family caregivers are often overlooked as a factor in care. This study therefore investigates the effectiveness of the STA OP! method (SOM), a stepwise approach to address problematic behaviour and pain in individuals with dementia, as well as how the efficacy of SOM is moderated by family involvement. The study, conducted within the CARED-4 project, utilizes a quasi-experimental longitudinal design with measurements at baseline, 3 months, and 6 months after implementing SOM. It included 84 residents with dementia from 10 Dutch nursing homes units paired with their family caregivers. Problematic behaviour was examined using the Neuropsychiatric Inventory Questionnaire (NPI-Q) and family involvement was examined through a tailored questionnaire. Analysis was performed with RM Anova for problematic behaviour and family involvement and a general linear model for the moderation of SOM by family involvement. Results indicated that SOM effectively reduces problematic behaviour overall (F(2,55) = 3.81, p = 0.028), after 3 months (Mean Difference = 5.47 SE= 1.97, p = 0.007), but not after 6 months (Mean Difference = 5.70 SE = 3.36, p = 0.095). Family involvement did not change overall (F(1.62,30) = 2.12, p = 0.138). Accordingly, family involvement did not moderate the impact of SOM on problematic behaviour (F(2) = 1.43, p = 0.243). Despite methodological challenges mainly due to missing data, the study takes a first step towards understanding how the effectiveness of SOM interacts with family involvement. So, although family involvement did not moderate a significant reduction in problematic behaviour, the efficacy of SOM has further been established.Show less

Although fatigue is the most common daytime symptom of insomnia, it is still largely unknown which underlying components are associated with fatigue in a broader population of insomnia patients. Previous literature stated that dysfunctional sleep-related beliefs (DSRB) and pre-sleep arousal (PSA) could explain the relationship between insomnia and fatigue. Additionally, subjective sleep characteristics, such as insomnia severity, number of nocturnal awakenings (NoA) and sleep efficiency might also be components of this relationship. This study aimed to investigate how these factors affect fatigue in a broad medical population with insomnia. It was hypothesized that more disturbed sleep-related psychological factors and subjective sleep characteristics were associated with increased fatigue. This cross-sectional study, derived from the ongoing TIMELAPSE study, consisted of 154 participants. Participants completed questionnaires assessing fatigue (Checklist Individual Strength-20), DSRB (Dysfunctional Beliefs and Attitudes about Sleep-16), PSA (Pre-Sleep Arousal Scale), and insomnia severity (Insomnia Severity Index). The Consensus Sleep Diary tracked NoA and sleep efficiency daily for one week. Two multiple regression analyses were performed to assess the relationship between sleep-related psychological factors (DSRB, PSA), subjective sleep characteristics (insomnia severity, NoA, sleep efficiency) and fatigue. Age, gender, and depression were included as controlling variables. Results showed that DSRB (β = .174, p = .027), PSA (β = -.160, p = .036), and insomnia severity (β = .243, p = .002) were factors associated with fatigue in insomnia patients. More severe DSRB and higher insomnia severity predicted elevated levels of fatigue. Contrary to expectations, PSA was negatively associated with fatigue. Lastly, NoA and sleep efficiency were not related to fatigue. This study uncovered connections between more severe DSRB, lower PSA, and higher insomnia severity that led to higher levels of fatigue. The current study suggests that improvements in DSRB and reducing insomnia severity may reduce fatigue of insomnia patients with long-term medical conditions. Sleep interventions should emphasize on challenging these DSRB. Future research is needed to examine the complex relationship between PSA and fatigue, as well as whether changes in DSRB during CBT-I treatment reduce fatigue symptoms in this population.Show less

Although digital tools can address the growing gap between healthcare supply and demand, their implementation is difficult, and personal factors can influence individuals’ intention to use such tools. Thus, this study explores the relationship between various personal factors, as self-reported by healthy individuals (N = 507) who are part of a brain research registry, and their intention to use and promote using digital tools in the context of brain health and dementia. According to the hypothesis formulated for the research, higher financial scarcity, lower educational attainment, and lower employment status predict lower intention to use and promote digital tools for brain health. The study examined four distinct digital tools: (1) MijnBreincoach (a prevention tool), (2) cCog (a diagnostic tool), (3) ADappt (a patient- orchestrated care tool), and Neurokeys (a prediction tool). It was found that Neurokeys exhibited the highest score for intention to use but the lowest score for intention to promote. In addition, medium and high educational attainment predicted higher behavioral intention to use MijnBreincoach, while the most beneficial (i.e., most secure, stable, and safe) employment status predicted higher intention to promote MijnBreincoach and cCog. In conclusion, it is important to recognize differences in intention to use and promote different types of digital tools across potential users and the influence of personal characteristics on the intention to use and promote digital tools for brain health. During the development of a digital tool, it is recommended to consider which target audience would derive the greatest benefit from it and tailor it accordingly.Show less

Participants were 127 adolescents aged between 10 and 14 years old who reported on their empathy, prosocial behavior, and self-perception of close friendships in three consecutive years, respectively. Simple mediation analyses revealed that cognitive and affective empathy did not have a significant positive effect on adolescents’ self-perception of close friendships two years later. Considering these findings, prosocial behavior was not found to be a mediator between adolescents’ cognitive or affective empathy and their self-perception of close friendships from late childhood to early adolescence. Moreover, cognitive and affective empathy did not significantly predict prosocial behavior one year later, whereas prosocial behavior did significantly predict the self-perception of adolescents’ close friendships one year later. These results underline the significance of developing tailored intervention programs targeting prosocial behavior to foster adolescents’ self-perception as close friends, a competence that is crucial during this developmental period considering the greater influence of peers.Show less

It is hypothesized that exercise of moderate and high intensity enhance creativity more effectively than exercise of lower intensity. The study also investigates if arousal, positive high-arousal affect, and negative high-arousal affect serve as intermediary variables in this relationship. Scarce previous research has suggested a relationship between exercise-intensity and creativity, but studies comparing different exercise-intensities on creativity and potential underlying mechanisms were lacking. To address this knowledge gap, this study compares different intensities, namely low-intensity (cycling at 55% of maximum heart rate), moderate-intensity (cycling at 70% of maximum heart rate), high-intensity (cycling at 85% of maximum heart rate) and a control group, on divergent creativity (i.e., number and uniqueness of creative ideas); And looks at affect and arousal as underlying mechanisms. Happy (positive), elated (positive), upset (negative), tense (negative) and stressed (negative) are used as indicators for high-arousal affect and feelings of wakefulness and alertness as indicators for arousal. Participants in this study completed two appointments, of which the first appointment consisted of a fitness test to measure participants’ maximum heart rate. During the second appointment, participants were randomly assigned to one of the four conditions and their affect and arousal were measured before and after the exercise or control task. Creativity was measured after the exercise or control task was completed. A Kruskal-Wallis Test showed that participants in the moderate-intensity and high-intensity exercise did not show higher creativity. Further, macro PROCESS model 4 revealed a significant effect of moderate-intensity and high-intensity exercise on arousal in comparison to low-intensity exercise and a significant effect of moderate-intensity exercise on positive high-arousal affect, in comparison to the control group. Other than this, the model revealed that none of the mediators significantly explained a relationship between exercise-intensity and creativity. This study thus suggests that exercise-intensity does not play a significant role in creativity enhancement, nor does arousal or high-arousal affect. However, future research is needed to confirm this for other modes of exercise, regular exercise instead of acute bouts of exercise and for different individual characteristics, such as age and gender.Show less

While TMS appears promising for stroke rehabilitation, there is variability in the level of improvement individuals exhibit. This variability may be attributed to oscillatory neurophysiology, which refers to the rhythmic electrical activity of the brain. Therefore, this study investigated phase-dependent changes in cortical excitability after TMS among stroke patients in affected and unaffected hemispheres. We investigated motor-evoked and TMS-evoked potentials at four phases of the ongoing motor cortical mu rhythm (trough, peak, rising, falling) in both hemispheres (affected, unaffected). Participants comprised N=11 chronic subcortical stroke patients (6 female, mean ± std age: 58 y ± 11.4) with affected lateralized upper-limb impairment. Four blocks of 150 TMS pulses were applied on each hemisphere, targeting the primary motor hotspot of the first dorsal interosseus muscle of the contralateral hand. Participants watched nature videos during stimulation to maintain consistent attention levels. Cortical excitability was assessed by analyzing motor-evoked potentials (MEP) and TMS-evoked potentials (TEP). Results showed that motor responses (measured through MEP amplitudes) were significantly larger at the trough and rising phase compared to the peak phase. No significant differences were observed between the affected and unaffected hemispheres. TEP components, the brain signals in response to TMS, did not exhibit significant phase-dependent changes. While our findings showed a nonsignificant effect of stroke severity, exploratory correlation analyses presented a positive association between higher remaining movement function and enhanced phase-dependent responses to TMS. The findings build upon previous research indicating phase-dependent changes in cortical excitability for MEPs but not for TEPs. The larger MEP amplitudes during trough and rising phases suggest that TMS can be more effective at specific points of cortical activity. Further exploration is needed to assess the efficacy of phase-specific TMS interventions in clinical settings, potentially through larger-scale clinical trials with longitudinal designs and comparative effectiveness studies, aiming to evaluate functional outcomes and determine their impact on motor recovery.Show less

The study investigated: (1) if there is an AB to or from itch; (2) whether this differs between people with chronic itch and healthy controls; (3) and if there is a possible AB/stress association. This is because understanding ABs to/from itch further elucidates the experience of patients with chronic itch and possible future clinical applications. Furthermore, an explorative analysis compared two tasks measuring AB, namely the Posner cueing and dot-probe task. The two tasks, alongside a stress-questionnaire, were administered online to the participants (N=70). A (frequentist and Bayesian) RM ANOVA was done for the main analysis, and a within- subjects t-test for the explorative task-comparison. Given that the task-comparison found the two tasks differing significantly (p = 0.01 d = -0.31), the results of the two tasks were interpreted separately. Overall, indications of AB being biased away from itch stimuli was found. When the AB was contrasted between participant group (people with and without chronic itch), the Posner cueing task found no significant difference (p = 0.68, ηp 2 = 0.003) whereas the dot-probe task found an AB away from itch-stimuli in patients with chronic itch (p = 0.02, ηp 2 = 0.077). Similar pattern unfolded with the stress-association: the Posner cueing task finding that AB did not significantly differ with stress (p = 0.23, ηp 2 = 0.021). The dot-probe task did find that they significantly differed (p = 0.01, ηp 2 = 0.091) where with higher stress, the AB switched to being an AB towards itch stimuli. The discrepancy between the two tasks aligns with expectations considering that the tasks were found inequivalent - highlighting one of the strengths of this study being that the two tasks were compared. Altogether this points towards differences in what the two tasks tap into, and that the attention of people with chronic itch is biased as a function of stress. Summarizing, AB to itch differed between the two groups and was associated with stress when using dot-probe task, which did not apply to the Posner cueing task.Show less

Research showed that individually expectancies and avoidance behaviour influence pain experience. However, there seems to be little research into the combined influence. Seeing that research also showed that pinpointing a cause for the chronic low back pain is difficult, this study aimed to give insight into interacting factors that influence chronic low back pain. To gather data participants (N=18) filled in a questionnaire five times a day for two weeks. This provided insight into their levels of pain in the morning and the evening, if they expected to experience pain and if they were more likely to avoid movements, they expected to be painful. These statements were answered with answering scales, ranging from 0 (not at all) to 6 (extremely), given how likely that statement was for the participant. A mediation analysis inspecting possible relations between the level of pain and expectancies, the level of pain and avoidance, and the level of pain, expectancies and avoidance yielded no significant relations. Therefore, it could not be concluded that avoidance and/or expectancy are influencing the level of pain in the evening when compared to the level of pain in the morning. There were two significant findings, the impact of level of pain in the morning on expectancies and the impact of expectancies on avoidance. These findings are in line with what was found in existing literature and give incitement for further research on this topic. Another incitement for further research is the small sample used in this current study. The implication for the scientific field therefore is to perform this study on a bigger sample. Another consideration for further research would be to try and use a more diverse sample in both age and gender, this to make a more representative sample to draw conclusions for the general population. This could also lead to more substantial implications for the clinical field since this study did not have significant results.Show less

It is important to know more about the distress experienced by parents during this period to determine whether an intervention should be used to help parents return to ‘normal life’. The aim of this study was therefore to gain better understanding of parental distress and factors related to their distress during the first year after their child has successfully completed treatment. Methods: A sample of 283 parents of children who had successfully completed cancer treatment in the previous year were included in this cross-sectional study. These parents, who were part of the SCOT group, were invited to complete the Distress Thermometer for Parents (DT-P) within one year after treatment completion. The DT-P consists of a thermometer score to measure experienced distress and problem domains (practical, social, emotional, physical, cognitive, and parenting). Parents in the SCOT group were compared with parents in the general population (NORM group) to see if their distress levels were higher. In addition, the association between distress and the problem domains and child- or parent-related factors (time since the end of treatment, cancer type, child’s age, parental disease, and perceived support) was examined. Results: Parents (73.9% mothers) in the SCOT group experienced higher levels of distress in the first year after SCOT compared to the general population (fathers SCOT: M=3.5, SD=2.6 vs. fathers NORM: M=2.8, SD=2.5; p=.032; mothers SCOT: M=4.1, SD=2.7 vs. mothers NORM: M=3.5, SD=2.7; p=.001). Emotional (p<.001), practical (p=.016), and physical (p=.005) problems were predictors of higher distress levels. Parents’ perceived support from their environment contributed also to their level of distress (p<.001). Conclusions: Parents of children who have successfully completed cancer treatment experience increased levels of distress in the first year after treatment compared to parents in the general population. There may be value in developing an intervention to ease this transition that specifically addresses their emotional well-being and highlights the importance of their social network during this vulnerable period.Show less

Sleep disruptions, notably insomnia, are prevalent in PD, worsening symptoms and affecting overall well-being and treatment outcomes. Moreover, individuals with PD frequently engage in cannabis use, which can further impact EF. Gender differences may also play a role in how cannabis affects EF, though findings are varied. This study aims to deepen our understanding of the interplay between insomnia, EF, and cannabis use in PD individuals, while considering gender influences. We hypothesize that higher insomnia rates correlate with poorer EF in PD, with cannabis mediating this relationship. Additionally, we expect gender disparities to influence how cannabis affects EF. This study sheds light on critical factors affecting cognitive function in PD, aiding in tailored intervention strategies. Method: Data were collected from a randomly selected sample of patients (N=262) undergoing treatment at a mental health care clinic in the South-western part of the Netherlands at time of inclusion. Participants, aged between 18 and 65 at inclusion, had a primary diagnosis of a psychotic disorder. The current study utilized data from the Lichamelijke Klachten Vragenlijst (LKV), the Behavior Rating Inventory of Executive Function for Adults (BRIEF-A), and the Measurements in Addictions for Triage and Evaluation (MATE). Results: Significant correlations indicated a moderate positive association between insomnia and EF problems. However, mediation analysis did not support cannabis use as a mediator between insomnia and EF. Gender differences were explored through residual variances analysis, suggesting potential unaccounted factors impacting variability. Model fit indices revealed areas for improvement in explaining variance, warranting further examination and potential adjustments to refine the overall model fit. Conclusion: Higher rates of insomnia were related to higher rates of EF problems. There is no evidence for a mediating effect of cannabis use in this relationship. Gender differences did not seem to play a significant role in the effect of cannabis on EF. Future research should incorporate performance-based tasks alongside self-report measures to improve measurement precision. Future treatments could potentially benefit from incorporating interventions that address insomnia, as this may lead to potential enhancements in executive functioning.Show less

Literature reports gender differences on emotional maltreatment and the experience of PTSD, so it is worth investigating the existence of differences when looking at separate symptoms. Objective: This study aims to investigate the correlation between childhood emotional maltreatment and PTSD symptomatology and identify gender differences in children and adolescents. Method: A sample of 237 children (mean age 15.5) with PTSD symptoms from a Dutch mental health institution (2012-2015) underwent assessment using anonymous questionnaires. Network analysis examined partial correlations between emotional abuse, neglect, intrusions, avoidance, arousal, and negative mood. Results: The network analysis showed a high correlation between emotional abuse and most PTSD symptoms. However, emotional neglect only exhibited a strong association with emotional abuse. Gender differences in how emotional maltreatment and PTSD symptoms interacted were found. Girls reported higher PTSD symptoms and emotional maltreatment than boys. Conclusions: This study highlights the important role of childhood emotional maltreatment in the development of PTSD, among children and adolescents. These results emphasize the need for the customization of PTSD treatment based on the type of maltreatment and gender.Show less
