Affiliate stigma in autistic and non-autistic parents of autistic children and the association with traumatic stress symptomatology
This study investigated the experience of affiliate stigma among autistic and non-autistic parents of autistic children in Denmark. The results showed a significant association between traumatic stress symptom severity and parent affiliate stigma whereby the more severe the traumatic stress symptoms experienced by a parent, the more affiliate stigma they experienced. The present study indicates that parents of autistic children may be particularl…
Posttraumatic stress symptoms in Australian parents of autistic children
Results strongly support the internal reliability and construct validity of the ICD-11 PTSD and CPTSD models in Australian parents of autistic children, as measured by the International Trauma Questionnaire. The ICD-11 models outperformed the best DSM-5 models, highlighting their superiority for this population. While more complex DSM-5 models showed better fit than simpler ones, they still did not achieve a good overall fit. Notably, the results…
The prevalence of posttraumatic stress disorder (PTSD) and complex PTSD among parents of autistic children in Denmark and Australia
Parents of autistic children in Denmark and Australia exhibit significantly higher rates of parenting-related PTSD and CPTSD compared to neurotypical parents, with strong diagnostic concordance across systems. Further research is needed to identify trauma-related outcomes in this population and clarify contributing risk and protective factors. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
Contribution of narrative identity and future autobiographical memories integration in the self on meaning and purpose in children
Anhedonia, apathy and a motivation are common experiences among young people. These variables are central symptoms of mental disorders, particularly in depression. Purpose in life has been shown to counteract depressive symptomatology, but this has hardly been studied in children. The construction of personal identity and episodic future thoughts are important variables in defining those purposes. Therefore, the present study investigates how all…
Guided recall of positive autobiographical memories increases anticipated pleasure and psychological resources, and reduces depressive symptoms
Reminiscence-based interventions focus on recalling autobiographical memories and reflective reasoning to develop a healthy and adaptive view of oneself and one's life.This study aimed to replicate the effects of a three-session, group-based, positive-memory version of cognitivereminiscence therapy (CRT) on psychological resources and mental well-being and extend the findings to anticipated pleasure.The participants (N = 75, M age = 43.7 (SD = 16…
Brief online suicide risk assessment of adults does not affect state mood, even in the context of elevated suicidality self‐stigma, suicidal ideation and psychological distress
The current study aimed to assess whether online suicide risk assessment affects state mood and is the first to examine if suicide‐related self‐stigma or coping related to suicidal ideation are predictors of mood change. The Australian participants ( N = 661, M age = 34.9, SD = 12.3, 57.1% female), recruited through a crowd‐sourcing platform, completed a visual analogue mood measure before and after the Suicidal Ideation Attributes Scale (SIDAS),…
Study protocol for a randomized controlled trial of the Raspera project
Background Many stress-related mental health problems, like depression and anxiety, emerge during adolescence, with some recent studies suggesting numbers are increasing. One possible way to reduce adolescents' vulnerability to stress-related mental health problems is to increase their resilience by training them in recalling specific positive memories and anticipating specific positive future events. Therefore, an innovative combi -training (cal…
Cognitive dependencies and psychological health correlates of coherence in autobiographical reasoning
Autobiographical reasoning is a process by which an individual creates a coherent life account. The degree of coherence in autobiographical reasoning has been related to psychological health correlates such as depression and self-esteem in previous studies, but with inconsistent findings. Similarly, the basic psychological processes required to achieve coherence have been previously studied with regard to intelligence, but infrequently, and also …
Selective effects of focusing on spatial details in episodic future thinking for self-relevant positive events
Mental simulations of positive future events increase their detail/vividness and plausibility, with effects on cognitive-affective processes such as anticipated and anticipatory pleasure. More recently, spatial details have been distinguished as important in increasing detail and elaborating mental scene construction. Building on this research, this study ( N = 54; M age = 26.9) compared simulations of positive, self-relevant future events spatia…
Direct accessibility for overgeneral memory predicts a worse course of depression
Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online c…
Toward a Global Definition and Understanding of Child Sexual Exploitation
Child sexual exploitation (CSE) is a serious and persistent global issue affecting up to 5% of the child and youth population worldwide; yet there is no universally accepted definition. To develop a theoretically robust definition of CSE, this review systematically synthesized literature examining CSE definitions aiming to develop a conceptual model and typology. Electronic databases were searched to February 2021, yielding 384 nonduplicative rec…
Remembering for Relationships
Reminiscence-based interventions involve the guided recall and interpretation of autobiographical memories to promote adaptive thinking. This study involved secondary analyses of a recent trial of a positively focused, group-based, three-session version of cognitive-reminiscence therapy (CRT) on perceptions of general relationship quality and interpersonally related psychological resources in young adults. A community sample ( N = 62, Mage = 24.6…
Direct retrieval bias for general and specific memories for negatively valenced cues in major depression
Major depressive disorder (MDD) is associated with reduced specificity in autobiographical memory. It has been argued that this tendency occurs through a failure of effortful generative retrieval, regardless of valence of cue word. However, we propose that in MDD general memories are likely to be recalled via direct retrieval, and direct retrieval is more likely for negatively valenced cues. To provide a preliminary test of this, a large sample w…
Specificity and detail in autobiographical memory retrieval
This investigation examined conflicting suggestions regarding the association between problems retrieving specific autobiographical memories and the tendency to retrieve the details of these memories. We also examined whether these tendencies are differentially related to depression symptoms. U.S., Belgian, Hong Kong and Japanese participants retrieved memories related to cue words. Responses were coded for if they referred to a specific event (i…
Sext Dissemination
Sext dissemination presents policy and legislative challenges given its potential psychological, social, and legal harms. We report on a cross-national comparison of sext-image dissemination in a large sample of 1148 young adults aged 18-29 years (M = 22.54, SD = 2.50, 53.0% women, 47.0% men), either U.S. (53.8%) or Australian (46.2%) residents. The results indicate that 14% of young adults disseminated sexts, with no difference by gender or coun…
Autobiographical memory impairments as a transdiagnostic feature of mental illness
712, 95% CI [0.524, 0.900], memories than diagnoses-free people. The size of these effects did not differ between diagnostic groups. There were no consistent moderators of effect size heterogeneity; effect sizes were not explained by methodological factors such as cue valence or demographic variables such as participants' age or between-group differences in process variables (e.g., rumination). Deficits in autobiographical memory retrieval may be…
Sharing is not always caring
Increasing anticipated and anticipatory pleasure through episodic thinking
Episodic future thinking for positive future events is known to evoke positive affect. We aimed to assess whether it specifically evokes anticipated and anticipatory pleasure for future events, and behavioral intention. As a secondary aim, we examined if this differed compared to a condition of thinking of positive past events. In two studies, participants nominated 5 upcoming positive events and 5 positive past events. They then completed guided…
The dark side of sexting – Factors predicting the dissemination of sexts
Sexting and Psychological Distress
Sexting (e.g., conveying nude electronic images) is now common among young adults. Despite leading to negative consequences for some (e.g., harassment and unwanted dissemination), findings regarding sexting behaviors and mental health variables have been mixed. We recruited a convenience sample of young adults (N = 444, M age = 20, SD = 1) to test the hypothesis that sexting might be associated with poorer mental health. Our results showed no ass…
A Qualitative Study of Young Adults Experience With a Reminiscence-Based Therapy for Depressive Symptoms
Reminiscence therapy is a novel psychosocial approach to treating depressive symptoms in young adults. We present the first qualitative inquiry into young adults’ experience of reminiscence-based therapy, aimed at exploring attitudes toward this approach and their view of processes underpinning positive change. Help-seeking young adults (mean age = 20.8, SD = 1.6) with at least moderate depressive symptoms were interviewed following a course of c…
The Effects of Victim Age, Perceiver Gender, and Parental Status on Perceptions of Victim Culpability When Girls or Women Are Sexually Abused
This study investigated perceptions of victim culpability in sexual assaults against girls and women according to victim age, perceiver gender, and perceiver parental status. Overall, 420 jury-eligible participants completed an online survey recording their attributions of guilt, responsibility, and blame toward 10-, 15-, and 20-year-old girls and women in relation to sexual assault. Attributions of culpability were affected by whether the victim…

Promoting fit bodies, healthy eating and physical activity among Indigenous Australian men
This study will explore both risk and protective factors that affect the health of Indigenous Australian men. This knowledge will be disseminated to the wider Indigenous community and can be used to inform future health promotion strategies. The expected outcome of this study is therefore an increased understanding of health and health change in Indigenous Australian men, the development of strategies that promote healthy eating and positive patt…
