Loneliness and psychosocial predictors of psychosis-proneness during COVID-19 : Preliminary findings from Croatia

The present study investigated psychosocial predictors of psychosis-risk, depression, anxiety, and stress in Croatia during the COVID-19 pandemic. Given Croatia's recent transgenerational war trauma and the relative lack of available prodromal data, this study presents a unique opportunity to examine the impact of loneliness and other psychosocial factors on psychosis-risk and mental health in this population. 404 Croatian participants completed an anonymous online survey of physical and mental health questions. 48 participants met the criteria for elevated psychosis-risk on prodromal questionnaire (PQ-16). Loneliness had a significant impact on psychosis-risk. Exposure to trauma was associated with psychosis-risk and loneliness, while domestic abuse/violence was associated only with the distress surrounding psychotic-like symptoms. COVID concern was also associated with psychosis-risk. Lastly, the associations between psychosis-risk and depression, anxiety, and stress were robust. These findings highlight the important role of loneliness in psychosis-proneness in Croatia. Depression, anxiety, and stress were also closely related to elevated psychosis-risk. Loneliness is a highly salient issue for individuals with psychosis and it is important to target loneliness within a multi-faceted psychosocial intervention for those at risk for schizophrenia

A comparative analysis of colour–emotion associations in 16–88‐year‐old adults from 31 countries

As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact their mood and overall well-being. However, there is a lack of empirical evidence to provide informed guidance on colour choices, irrespective of age group. To work towards informed choices, we investigated whether the associations between colours and emotions observed in younger individuals also apply to older adults. We recruited 7,393 participants, aged between 16 and 88 years and coming from 31 countries. Each participant associated 12 colour terms with 20 emotion concepts and rated the intensity of each associated emotion. Different age groups exhibited highly similar patterns of colour-emotion associations (average similarity coefficient of 0.97), with subtle yet meaningful age-related differences. Adolescents associated the greatest number but the least positively biased emotions with colours. Older participants associated a smaller number but more intense and more positive emotions with all colour terms, displaying a positivity effect. Age also predicted arousal and power biases, varying by colour. Findings suggest parallels in colour-emotion associations between younger and older adults, with subtle but significant age-related variations. Future studies should next assess whether colour-emotion associations reflect what people actually feel when exposed to colour

The sun is no fun without rain : Physical environments affect how we feel about yellow across 55 countries

Across cultures, people associate colours with emotions. Here, we test the hypothesis that one driver of this cross-modal correspondence is the physical environment we live in. We focus on a prime example – the association of yellow with joy, – which conceivably arises because yellow is reminiscent of life-sustaining sunshine and pleasant weather. If so, this association should be especially strong in countries where sunny weather is a rare occurrence. We analysed yellow-joy associations of 6625 participants from 55 countries to investigate how yellow-joy associations varied geographically, climatologically, and seasonally. We assessed the distance to the equator, sunshine, precipitation, and daytime hours. Consistent with our hypotheses, participants who live further away from the equator and in rainier countries are more likely to associate yellow with joy. We did not find associations with seasonal variations. Our findings support a role for the physical environment in shaping the affective meaning of colour.Peer reviewe

A comprehensive approach to heightened stress-sensitivity as a psychosis-proneness mechanism

Com a mecanisme de risc putatiu per a la psicosi, la tesi actual investiga el complex fenotip de la sensibilitat a l'estrès en un ampli espectre de contextos i períodes de temps. Ofereix una investigació en profunditat de l'adversitat infantil amb un enfocament particular en els fenotips relacionats amb l'esquizofrènia, així com en les puntuacions de risc poligènic per predir trajectòries longitudinals de sensibilitat a l'estrès. A més, aquesta tesi explora altres factors psicosocials relacionats que són importants factors de risc i de protecció en la psicosi davant la situació de vida altament estressant i incerta de la pandèmia de la COVID-19.Como mecanismo de riesgo putativo para la psicosis, la tesis actual investiga el complejo fenotipo de la sensibilidad al estrés en un amplio espectro de contextos y marcos temporales. Ofrece una investigación en profundidad de la adversidad infantil con un enfoque particular en los fenotipos relacionados con la esquizofrenia, así como en las puntuaciones de riesgo poligénico para predecir las trayectorias longitudinales de la sensibilidad al estrés. Además, esta tesis explora otros factores psicosociales relacionados que son factores de riesgo y protección significativos en la psicosis ante la situación altamente estresante e incierta debida a la pandemia de COVID-19.As a putative risk mechanism for psychosis, the current thesis investigates the complex phenotype of stress-sensitivity across a broad spectrum of contexts and timeframes. It offers an in-depth investigation of childhood adversity with a particular focus on schizophrenia-related phenotypes as well as polygenic risk scores in predicting longitudinal trajectories of stress-sensitivity. More so, this thesis explores other related psychosocial factors that are both significant risk and protective factors in psychosis in the face of the highly stressful and uncertain life situation of the COVID-19 pandemic

Social connectedness and resilience post COVID-19 pandemic: Buffering against trauma, stress, and psychosis

The present study investigated psychosocial predictors of psychosis-risk, depression, anxiety, and stress in Croatia two years after the onset of the COVID-19 pandemic. Given the existing transgenerational war trauma and associated psychiatric consequences in Croatian population, a significant pandemic-related deterioration of mental health was expected. Recent studies suggest that after an initial increase in psychiatric disorders during the pandemic in Croatia, depression, stress, and anxiety rapidly declined. These findings highlight the role of social connectedness and resilience in the face of the global pandemic. We examined resilience and psychiatric disorder risk in 377 Croatian adults using an anonymous online mental health survey. Results indicate that there was an exacerbation of all mental ill health variables, including depression, anxiety, stress, and a doubled risk for psychosis outcome post-COVID pandemic. Stress decreased levels of resilience, however, those exposed to previous traumatic experience and greater social connectedness had higher resilience levels. These findings suggest that individual differences in underlying stress sensitization of Croatian population due to past trauma may continue to influence mental health consequences two years after COVID-19 pandemic. It is essential to promote the importance of social connectedness and resilience in preventing the development of variety of mental health disorders

Empirically-derived dimensions of childhood adversity and cumulative risk : associations with measures of depression, anxiety, and psychosis-spectrum psychopathology

Background: Investigating different approaches to operationalizing childhood adversity and how they relate to transdiagnostic psychopathology is relevant to advance research on mechanistic processes and to inform intervention efforts. To our knowledge, previous studies have not used questionnaire and interview measures of childhood adversity to examine factor-analytic and cumulative-risk approaches in a complementary manner. Objective: The first aim of this study was to identify the dimensions underlying multiple subscales from three well-established childhood adversity measures (the Childhood Trauma Questionnaire, the Childhood Experience of Care and Abuse Interview, and the Interview for Traumatic Events in Childhood) and to create a cumulative risk index based on the resulting dimensions. The second aim of the study was to examine the childhood adversity dimensions and the cumulative risk index as predictors of measures of depression, anxiety, and psychosis-spectrum psychopathology. Method: Participants were 214 nonclinically ascertained young adults who were administered questionnaire and interview measures of depression, anxiety, psychosis-spectrum phenomena, and childhood adversity. Results: Four childhood adversity dimensions were identified that captured experiences in the domains of Intrafamilial Adversity, Deprivation, Threat, and Sexual Abuse. As hypothesized, the adversity dimensions demonstrated some specificity in their associations with psychopathology symptoms. Deprivation was uniquely associated with the negative symptom dimension of psychosis (negative schizotypy and schizoid symptoms), Intrafamilial Adversity with schizotypal symptoms, and Threat with depression, anxiety, and psychosis-spectrum symptoms. No associations were found with the Sexual Abuse dimension. Finally, the cumulative risk index was associated with all the outcome measures. Conclusions: The findings support the use of both the empirically-derived adversity dimensions and the cumulative risk index and suggest that these approaches may facilitate different research objectives. This study contributes to our understanding of the complexity of childhood adversity and its links to different expressions of psychopathology
