Heart rate increase predicts challenging behavior episodes in preschoolers with autism.

Identifying triggers for challenging behavior is difficult in some children with autism because of their limited communication abilities. Physiological indicators of stress may provide important insights. This study examined whether heart rate (HR) predicts challenging behavior in children with autism. While wearing an electrocardiograph monitor, 41 children with autism aged 2- to 4-years participated in tasks designed to induce low-level stress (e.g. waiting for a snack). Coders identified 106 time periods during which challenging behaviors occurred and also coded 106 randomly selected time samples that did not include challenging behaviors. Thirteen (32%) participants exhibited challenging behaviors and were included in the study. Baseline-corrected HR was computed for each behavior/time sample. On average, children with autism showed a 22 ± 16% HR increase from baseline 58 ± 22 seconds before the onset of a challenging behavior episode. Peak HR change had moderate predictive utility (area under the curve = .72, p < .001). The increase in HR before challenging behaviors was similar for children of different characteristics (age, autism severity, expressive language ability, overall developmental ability). Results highlight the promise of using physiological stress to predict challenging behavior in preschoolers with autism; although, they need to be replicated in larger samples. Given recent advances in wearable biosensing, it may be useful to incorporate HR monitoring in autism intervention. Lay summary In children with autism, changes in heart rate (HR) may help us predict when challenging behavior is about to occur - but this hypothesis has not been well studied. In this study, HR increase moderately predicted challenging behavior in preschoolers with autism. Given recent advances in wearable sensors, it may be useful to incorporate HR monitoring in autism intervention.

Risk and protective factors underlying depression and suicidal ideation in Autism Spectrum Disorder.

BACKGROUND: People with Autism Spectrum Disorder (ASD) are at significantly increased risk of suicidal thoughts and behavior. Given that social difficulties in ASD often lead to social isolation, which can in turn increase the risk for depression, this study examined loneliness and social support as potential risk and protective factors associated with depression and suicidal ideation. METHOD: The sample comprised 185 people (92 females) with ASD aged 14 to 80 years who were participating in a national survey. RESULTS: Forty-nine percent of participants returned scores in the clinical range for depression and 36% reported recent suicidal ideation. Females, comprising almost 50% of the sample, returned higher depression scores than males, however no differences were identified between males and females in terms of suicidal ideation. Regression analyses revealed that loneliness, satisfaction with social support, and ASD traits predicted depression scores. Satisfaction with social support predicted suicidal ideation, however, it was no longer a significant predictor after the effects of depression were taken into account. Path analysis showed that ASD trait severity was independently related to depression, that the effect of number of social supports on depression was mediated by loneliness and satisfaction with social support, and that effects of loneliness and satisfaction with social support on suicidal ideation were mediated by depression. The pattern of relationships was nearly identical for males and females. CONCLUSIONS: This study supports a model whereby loneliness and social support operate respectively as protective and risk factors for depression and suicidal ideation in ASD.

Does hope mediate the relationship between parent's resolution of their child's autism diagnosis and parental stress.

Introduction: Resolution of a child's diagnosis, the process of accepting and adjusting to the reality of a child's significant diagnosis, has been often associated with decreased parental stress. Hope, a potential buffer against psychological distress, has been suggested as a potential explanation for this relationship. However, the mediating role of hope in the relationship between resolution of diagnosis and parental stress has not been explored. Methods: This study aimed to examine whether four types of hope (child, parental, societal, denial of diagnosis) mediated the relationship between resolution to an autism diagnosis and reduced parental stress. Participants included 73 parents (Mage = 43.22, SD = 7.69, female 97.3%) of autistic children (Mage = 11.15, SD = 4.56, male = 67.1%). Results: Resolution to diagnosis was negatively and significantly correlated with resolution to diagnosis, as well as child, parental and societal hope. These three hopes were also significantly and negatively correlated with parental stress. Importantly, when controlling for level of support and autism awareness, parental hope mediated the relationship between resolution to diagnosis and parental stress. Denial of diagnosis was not correlated with resolution or parental stress but did have significant but weak associate with the other hopes. Discussion: These findings suggest that hope based on parent's abilities to support their child and be supported themselves play an important role in parental stress once parents are more resolved to their child's diagnosis. Supporting parents to manage factors associated with supporting their child's needs, may benefit parents of autistic children.

The Relationship Between Autistic Traits and Quality of Life: Investigation of Indirect Effects Through Self-Determination.

Background: Self-determination, described broadly as experiencing causal agency, is positively associated with quality of life (QoL) and increases through satisfaction of three basic psychological needs: autonomy (feeling able to make choices free from pressure), competence (perceived self-efficacy), and relatedness (social connection). Both unsupportive environments and challenges with social interaction can interfere with satisfaction of psychological needs. Social challenges are a key trait for autism diagnosis, and unsupportive environments are also known to adversely affect QoL for autistic people. Autistic people report, on average, lower self-determination than non-autistic people. Therefore, it is hypothesized that higher levels of autistic traits may reduce opportunities to develop self-determination, affecting QoL. Methods: We tested a parallel indirect effects model where we hypothesized that the relationships between autistic traits and four domains of QoL (psychological, social, physical, and environmental) would be indirectly influenced through self-determination (represented through satisfaction of the basic psychological needs for autonomy, competence, and relatedness). This study drew participants from the general population (N = 262; M AGE = 37.6, standard deviation = 11.92; 1.9% reported an autism diagnosis and 2.7% identified as autistic without a diagnosis). Participants completed an online survey. Results: Higher levels of autistic traits were associated with lower levels of self-determination and lower levels of QoL, and there was a significant indirect effect between autistic traits and QoL via self-determination. More specifically, we found a significant indirect effect between autistic traits and all QoL domains via competence; between autistic traits and the environmental, social, and psychological QoL domains via relatedness; and between autistic traits and the physical and environmental QoL domains through autonomy. Conclusions: Our results suggest that supporting satisfaction of the needs for autonomy, competence, and relatedness may represent an important element in designing effective programs to support the development of self-determination in people with higher levels of autistic traits (potentially including autistic individuals) and also to support these people to improve their QoL.

Why is this an important issue? In this study, we looked at how autistic traits might affect self-determination and quality of life. Quality of life is the way that you feel about your own life circumstances. In this study, we looked at four aspects of quality of life­psychological (e.g., mental health), social (how you interact with other people), physical (e.g., disability or sickness), and environmental (e.g., where you live). Self-determination is the ability to choose based on your own wants, needs, and interests, without feeling pressured. To be self-determined, you need to meet your needs for autonomy (experiencing free choice), competence (feeling able to do things effectively), and relatedness (feeling connected with others). Meeting these needs is affected by the world around you (e.g., where you live, if you have a job, whether you are disabled) and by the actions and beliefs of the people around you. People with higher autistic traits report, on average, lower quality of life and self-determination than people with lower autistic traits. Because other researchers have found that self-determination influences quality of life, lower levels of self-determination might partly explain lower quality of life. Programs that promote self-determination may reduce the gap in quality of life between autistic and non-autistic people. What was the purpose of this study? We thought that self-determination might partly explain why people with higher autistic traits report lower quality of life than people with lower autistic traits, so we wanted to test this idea. What did the researchers do? We asked people to answer questions about autistic traits, self-determination, and quality of life in an online survey. We statistically analyzed their answers to find out whether autistic traits influenced the levels of self-determination (feelings of autonomy, competence, and relatedness) or quality of life (psychological, social, physical and environmental quality of life). What were the results of this study? Autistic traits did not directly influence psychological, physical, or environmental quality of life but did directly influence social quality of life. In our study, people with higher autistic traits reported less satisfaction of their psychological needs than people with lower autistic traits. People with lower satisfaction of psychological needs also reported lower quality of life. Autistic traits influenced self-determination, which in turn influenced quality of life. What do these findings add to what was already known? To the best of our knowledge, this was the first study to explore relationships between autistic traits, self-determination, and quality of life. Our results showed that people with higher levels of autistic traits may report lower quality of life partly because autistic traits might make it difficult to become self-determined. What are the potential weaknesses in the study? We investigated self-determination and quality of life among one group of people from the general population. We did not compare autistic and non-autistic people. While some studies have shown that people with high levels of autistic traits may be similar to autistic people in some ways, this is not necessarily the case all the time. We cannot assume that results will be the same in other groups, that autistic traits cause lower self-determination, or that lower self-determination causes lower quality of life. We also did not consider all the things that might have influenced self-determination or quality of life (e.g., where people lived, how much money they had, or what their health was like). How will these findings help autistic adults now or in the future? People with higher autistic traits (including autistic adults) may find it harder to be self-determined both because of their autistic traits (e.g., difficulty in social interaction, sensory sensitivities) and also because school, work, and community systems may not be designed to support acceptance of differences. The results from this study suggest that higher autistic traits might make it difficult to meet the psychological needs for autonomy, competence, and relatedness. Research that compares autistic and non-autistic people is needed to determine both personal and environmental factors which may support the development of self-determination in autistic people and empower them to achieve higher quality of life.

A repeated cross-sectional study of daily activities of autistic adults.

It is crucial to arrive at a comprehensive understanding of the types of daily activities autistic adults typically engage in. However, previous research has almost exclusively focused on vocational or education activities. Further, it remains unclear how and whether specific daily activities participation rates change proportionally over time, vary by gender, or compare to nationally representative data. Utilizing eight annual data waves from the Netherlands Autism Register (NAR) this study aims to bridge this gap. Participants were 2449 autistic adults who indicated their participation in 18 daily activities. Results suggest that autistic adults engaged most frequently in vocational activities (e.g., paid employment, study) and participation rates were stable over time. Participation rates in non-vocational activities (e.g., hobbies, homemaking) fluctuated proportionally over time, with reports of no structured daytime activities reducing over time. Labor force participation amongst NAR participants was significantly lower than Dutch population data for the same time periods. Unemployment rates fluctuated, and were significantly higher than population data, but not for all time points. Females compared to males were overrepresented in unpaid daily activities (e.g., study, volunteer, housemaker) and work incapacitation, and underrepresented in paid employment. Employment differences in gender corresponded to national data. These findings characterize more clearly the daily activities of autistic adults, and highlights areas where support may have greater impact (e.g., females in employment).

Employment profiles of autistic people: An 8-year longitudinal study.

LAY ABSTRACT: Autistic adults experience difficulties finding and keeping employment. However, research investigating reasons that might explain this difficulty produce mixed results. We gave a survey to 2449 autistic adults and used a statistic method to group them based on their employment status over 8 years. We identified four employment groups that best captured the experiences of autistic adults; this included a group that experienced stable unemployment, a group that experienced stable employment, a group that had high employment that reduced over time, and a group whose employment increased over the 8 years. Further analysis showed that those with fewer autistic traits, younger age, male gender, higher education, later diagnosis age and no co-occurring conditions were more likely to have stable employment. People whose employment changed over time were more likely to have a higher level of education than the stable unemployment group, and those in the increasing employment group were younger age and had no co-occurring conditions. These findings help us better understand that not all autistic adults' experiences of employment are the same, which helps focus where employment programmes and support may be most needed, for example, people who identify as women or have a co-occurring condition.

Subjective wellbeing of autistic adolescents and young adults: A cross sectional study.

Subjective wellbeing (SWB) represents an individual's perception of wellness that is supported by homeostatic mechanisms. These mechanisms are proposed to be maintained by low negative affect and high positive affect, although less is known about these mechanisms and SWB in autism. The current cross-sectional study aimed to compare patterns of positive affect, negative affect (Positive Affect and Negative Affect Scale), and SWB (Personal Wellbeing Index-School Children) between autistic (n = 53) and non-autistic (n = 49) individuals aged 10-22 years (Mage = 13.97, SD = 3.13). Between-group t-tests revealed that compared with same-age peers, autistic participants scored lower SWB overall (p < 0.001). In both groups average SWB scores fell into the higher range, however, autistic participants were three-times more likely to fall below this range when compared to non-autistic participants. Negative affect had a higher intercept in the autistic sample, but no difference in slopes were observed. A hierarchical multiple regression revealed that diagnosis, positive affect, and negative affect significantly predicted SWB in our sample. Between-group t-tests found no significant difference in positive affect or negative affect across age between the autistic and non-autistic samples. In autistic participants, positive affect increased across age as SWB decreased, whilst negative affect remained stable, a pattern inconsistent with homeostatic SWB. The current study is overall consistent with the homeostatic explanation for SWB within autism; however, we identified potential differences between autistic and non-autistic participants in the contribution of positive affect and negative affect to homeostatic protect mood across development.

An ecological systems model of employee experience in industry-led autism employment programmes.

LAY ABSTRACT: We asked 33 autistic adults from two industry-led employment programmes about their experiences in the programmes. These are programmes started by companies to recruit and support autistic people in work. We also asked about their workplace supports, relationships and how they thought the programme had impacted their life. Understanding the experiences of people in these industry-led employment programmes is important as the information can help to improve the programmes and participants' experiences. After reviewing the interviews, we found five themes that best described the employee's experience: (1) working involves multiple job tasks that evolve as the employment context changes; (2) relationships in the workplace are diverse and are influenced by the type of work participants do and the work environment; (3) workplace needs change as the autistic employees learn to navigate their work environment; (4) autistic employees develop a professional identity in the workplace as they master work and feel more integrated in the workplace; and (5) recommendations for the development of supportive workplace environments for autistic people. We explored the way that aspects of the two employment programmes (e.g. training) and factors outside the programme changed with time and contributed to the participant's experience. We developed a new model to capture individual and workplace factors that contribute to the experience of autistic people who participate in industry employment programmes.

The global burden of suicide mortality among people on the autism spectrum: A systematic review, meta-analysis, and extension of estimates from the Global Burden of Disease Study 2021.

We aimed to quantify the risk, mortality, and burden of suicide among autistic persons. We searched PubMed, Embase, and PsycINFO on 5th April 2023 for sources reporting the relative risk (RR) of suicide or suicide attempt among autistic persons (PROSPERO registration: CRD42021265313). Autism spectrum prevalence and suicide mortality and years of life lost (YLLs), were sourced from the Global Burden of Disease Study 2021. RRs pooled via meta-regression and health metrics estimates were used to estimate the excess suicide mortality and YLLs among autistic persons. We sourced 983 unique studies of which ten studies met inclusion criteria, consisting of 10.4 million persons. The pooled RR for suicide for autistic persons was 2·85 (95% UI: 2·05-4·03), which was significantly higher for autistic females than autistic males. No evidence of publication bias was detected via inspection of funnel plot and Egger's test. Globally, we estimated 13 400 excess suicide deaths among autistic persons in 2021, equating to 1·8% of all suicide deaths and 621 000 excess YLLs. Studies were limited in number and geographical coverage. Effective suicide prevention strategies for autistic persons may substantially reduce the fatal burden of suicides globally and reduce the health burden experienced within this population.

Examination of the Potential Moderating Role of Psychological Wellbeing in the Relationship Between Depression and Thoughts of Self-Harm in Autistic Adolescents and Adults: A Two-Year Longitudinal Study.

PURPOSE: Autistic people have a significantly increased risk of death by suicide relative to the general population. In non-autistic samples, psychological wellbeing has been shown to moderate the relationship between depression and suicidal thoughts and behavior. Thoughts of self-harm may provide a useful indicator of suicidal risk. In this longitudinal study we examined (a) the potential role for psychological wellbeing to moderate the relationship between depressive symptoms and thoughts of self-harm and (b) the contribution of autistic traits to thoughts of self-harm. METHODS: Participants were 209 autistic adolescents and adults aged 15 to 80 years (Mage = 34.20, SD = 15.38 years). RESULTS: At both baseline and 2-year follow-up, 35% of participants reported recent thoughts of self-harm. Wellbeing was associated with autistic traits (r = - .350 to - 0.404) and depression (r = - .480 to - 0.759). Thoughts of self-harm were positively associated with autistic traits and depression (r = .242 to 0.659), and negatively associated with wellbeing (r = - .287 to - 0.609). Controlling for baseline thoughts of self-harm, depression (ß = 0.254, p = .001) and autistic traits (ß = 0.162, p = .007) significantly predicted thoughts of self-harm at 2-year follow-up. CONCLUSION: Despite a lack of support for the hypothesis that wellbeing would moderate the relationship between depression and thoughts of self-harm, correlational data demonstrated significant associations between wellbeing and both depression and thoughts of self-harm. Future research considering psychological wellbeing as a potential protective factor for self-harm in autistic people is warranted.

Physiological and communicative emotional disconcordance in children on the autism spectrum.

BACKGROUND: Individuals on the autism spectrum commonly have differences from non-autistic people in expressing their emotions using communicative behaviors, such as facial expressions. However, it is not yet clear if this reduced expressivity stems from reduced physiological reactivity in emotional contexts or if individuals react internally, but do not show these reactions externally to others. We hypothesized that autism is characterized by a discordance between in-the-moment internal psychophysiological arousal and external communicative expressions of emotion. METHODS: Forty-one children on the autism spectrum and 39 non-autistic, typically developing (TD) children of two age groups (2-4 and 8-12 years) participated in a low-level stress task whilst wearing a wireless electrocardiogram. Children's negative emotional expressions (facial, vocal, bodily) were coded following standardized protocols. Alexithymia traits were assessed using the Children's Alexithymia Measure with school-aged children only. Data analyses involved ANOVAs, correlations, and sensitivity analyses. RESULTS: There were no group differences in physiological arousal (heart rate) or in communicative expressions of stress to the stress task. For TD preschoolers, physiological arousal during the stress task was associated with vocal expressions and for TD school-aged children, they were associated with facial and bodily expressions. By contrast, for children on the autism spectrum, physiological arousal during the stress tasks was not associated with communicative expressions across age groups. CONCLUSIONS: Our findings suggest that children on the autism spectrum might experience emotional disconcordance, in that their physiological arousal does not align with their communicative expressions. Therefore, the internally experienced stress of children on the autism spectrum may be inadvertently missed by teachers and caregivers and, consequently, learning opportunities for teaching emotional communication and regulation may be also missed. Our results support the use of wearable biosensors to facilitate such interventions in children on the autism spectrum.

The stereotype content model and disabilities.

Using the stereotype content model and behavior from intergroup affect and stereotypes map model, we examined whether stereotype content directed toward specific disabilities conforms to the high warmth/low competence stereotype associated with "disabled people" or whether individual disabilities, or clusters, would elicit different stereotypes. Participants from the USA rated 12 disabilities on perceived warmth, competence, courage, emotions and behavioral tendencies. All disabilities, except schizophrenia and disability, were rated higher in warmth than competence. Four clusters emerged, varying on relative warmth, competence and courage. Pity was the highest rated emotion, and negative behavioral intentions were generally low. Perceived warmth predicted positive behavioral intentions, but mean ratings suggest actual help might be minimal. Results suggest some uniformity in stereotypes of different disabilities, but some variation in stereotypes indicates the need for targeted interventions to reduce prejudice and discrimination against disabled people.

"It Defines Who I Am" or "It's Something I Have": What Language Do [Autistic] Australian Adults [on the Autism Spectrum] Prefer?

There has been a recent shift from person-first to identity-first language to describe autism. In this study, Australian adults who reported having a diagnosis of autism (N = 198) rated and ranked autism-terms for preference and offensiveness, and explained their choice in free-text. 'Autistic', 'Person on the Autism Spectrum', and 'Autistic Person' were rated most preferred and least offensive overall. Ranked-means showed 'person on the autism spectrum' was the most preferred term overall. Six qualitative themes reflected (1) autism as core to, or (2) part of one's identity, (3) 'spectrum' reflecting diversity, (4) the rejection of stigmatising and (5) medicalised language, and (6) pragmatics. These findings highlight the importance of inclusive dialogue regarding individual language preference.

'If I'm just me, I doubt I'd get the job': A qualitative exploration of autistic people's experiences in job interviews.

LAY ABSTRACT: When applying for a job, autistic job candidates are likely to face a number of challenges. Job interviews are one of these challenges - they require communicating and relationship-building with unfamiliar people and involve expectations about behaviour (that may vary between companies and are not made clear to job candidates). Given autistic people communicate differently to non-autistic people, autistic job candidates may be disadvantaged in the interview process. Autistic candidates may not feel comfortable or safe sharing with organisations their autistic identity and may feel pressure to hide any characteristics or behaviour they feel might indicate they are autistic. To explore this issue, we interviewed 10 autistic adults about their job interview experiences in Australia. We analysed the content of the interviews and found three themes that related to the individual person and three themes that related to environmental factors. Participants told us that they engaged in camouflaging behaviour during job interviews, feeling pressure to conceal aspects of themselves. Those who camouflaged during job interviews reported that it took a lot of effort, which resulted in increased stress, anxiety and exhaustion. The autistic adults we spoke to reported a need for inclusive, understanding and accommodating employers to help them feel more comfortable disclosing their autism diagnosis in the job application process. These findings add to current research that has explored camouflaging behaviour and barriers to employment for autistic people.

Understanding language preference: Autism knowledge, experience of stigma and autism identity.

LAY ABSTRACT: There is ongoing discussion around what language is acceptable when talking about someone with an autism diagnosis, especially regarding person-first (e.g. person with autism) or identity-first (e.g. autistic person) language. We asked 198 Australian adults with an autism diagnosis what terminology they prefer and what they find offensive. We also asked questions to understand their experience of stigma, their autism knowledge and how much they endorse an autism identity, to investigate if these factors were associated with their language preferences. Overall, there was no significant association between these three factors and person-first terminology. For identity-first terms, those who endorse a stronger autism identity tended to find identity-first terms more preferable and less offensive, whereas those who reported greater experiences and internalisation of stigma tended to find identity-first terms less preferable and more offensive. Previous research has tended to ask what language participants prefer. The findings of this work help provide some context as to why people prefer or find offensive specific terms, at least for identity-first language.

Cost-benefit analysis of a non-government organization and Australian government collaborative supported employment program for autistic people.

LAY ABSTRACT: Relative to the size of the population, there are fewer autistic people than non-autistic people in the workforce. Employment programs that provide extra support to autistic people may help them to gain and keep jobs that are suited to their skills and expertise. In this study, we reviewed the DXC Dandelion Program. This is a supported autism employment program run in partnership with the Australian Government. The program provided jobs to autistic people who worked in information and communications technology roles, such as software testing and cyber security. In this study, we examined some of the benefits of the program for the autistic people who participated in it. We also examined the benefits of the program to the government. We found that there are many savings to government when autistic people are employed in jobs that are matched to their skills and abilities, compared to being unemployed or working in jobs that are below their level of education, training, or skills.

The Efficacy of Disability Employment Service (DES) Providers Working with Autistic Clients.

The efficacy of the Australian Disability Employment Services (DES) for autistic jobseekers has not been examined and is currently undergoing Government reform. To help inform the new DES strategy, we sought the views of: 24 autistic individuals; seven family members of autistic individuals, and; 46 DES employees. Data were collected using surveys and interviews. Data were analysed using Mann Whitney tests plus deductive thematic analysis based on Nicholas and colleagues' ecosystems model. Participants highlighted a need to adapt existing policies to enhance flexibility of the DES model. There was participant consensus that DES staff require specific education and training to meet the needs of autistic people. Suggestions to inform the new model of DES for autistic people are made.

The Suicidal Ideation Attributes Scale-Modified (SIDAS-M): Development and preliminary validation of a new scale for the measurement of suicidal ideation in autistic adults.

LAY ABSTRACT: Autistic people may be at higher risk of suicidal behavior than people in the general population. Suicidal behavior may include thinking about suicide or attempting to end one's own life by suicide. It is important to identify autistic people who may be thinking about suicide. People who are at risk of suicidal behavior can be identified by asking questions about whether they have been thinking about suicide. A specially designed questionnaire, or screening instrument, can help someone ask the best questions to find out if someone has been thinking about suicide. This information can help to identify supports to be put in place to prevent suicidal behavior, such as a suicide attempt. However, autistic people may interpret questions differently than non-autistic people. It is important to use screening tools that have been designed with, and for autistic people. In this study, we examined the Suicidal Ideation Attributes Scale (SIDAS). The SIDAS is an existing tool that was developed to screen for suicidal thinking in the general population. We modified SIDAS for use with autistic adults. We involved autistic people in the process of modifying SIDAS. We called the modified instrument the SIDAS-M. The results of our study showed SIDAS-M may be useful for screening for suicidal thinking in autistic adults who do not have an intellectual disability.

Factors associated with parental resolution of a child's autism diagnosis: A systematic review.

Background: Receiving a child's autism diagnosis can be stressful; as such, parent resolution contributes to the wellbeing and development of healthy parent-child relationships. In other significant childhood diagnoses (e.g., cerebral palsy, diabetes), the degree to which parents adjust to (a) their child's diagnosis and (b) their changes in expectations concerning their child's development and capacity (referred to as resolution to diagnosis), has been associated with improved outcomes including facilitating parent-child relationships and improved parental wellbeing. Given potential benefits to parent and child, and the heterogenous nature of autism, examining the unique factors associated with resolution to diagnosis is important. In this systematic review we identified factors that support or inhibit parental resolution to their child receiving a diagnosis of autism. Methods: We completed a systematic review following PRISMA guidelines of peer-reviewed studies from 2017 to 2022, that investigated parental resolution or acceptance of an autism diagnosis. Papers including "acceptance" needed to encompass both accepting the diagnosis and the implications regarding the child's abilities. We searched six databases (Scopus, Web of Science, MEDLINE, PsycINFO, ProQuest), with additional papers located following review of reference lists. Results: Fourteen papers with 592 participants that investigated parental resolution or acceptance of an autism diagnosis, were included. We identified six common factors that facilitate or inhibit parental resolution and acceptance of an autism diagnosis including: symptom severity; religion, belief, and culture; knowledge and uncertainty; negative emotions (i.e., denial, shame, guilt); positive emotions; and support. Greater resolution was associated with improved "attunement and insightfulness" in the parent-child relationship. Limitation: The review was limited by the small number of studies meeting inclusion criteria. Second, the quality of included studies was mixed, with over half of the studies being qualitative and only one randomized control trial (RCT) identified. Conclusion: Parental resolution can have an impact on parent's perception of their child's capabilities and impact the parent-child relationship. We identified six categories that aid in inhibiting or promoting resolution to diagnosis. Despite taking a broad approach on the definition of resolution, the low number of studies identified in the review indicates a need for more research in this area.
