Feasibility and Preliminary Evaluation of Theory-Based Training Program on Daily Living Skills Among Children With Autism Spectrum Disorder: Findings From Rural Regions in Egypt.

BACKGROUND: One of the most crucial objectives in the education and treatment of young children with autism spectrum disorder (ASD) is independence in daily living skills (DLS). Therefore, as a child with ASD condition grows, measures of everyday functioning including adaptive behaviors should be more regularly monitored and regulated. AIM: The primary aim of this study was to evaluate the feasibility of a developed theory-based training program and its preliminary effectiveness on the acquisition of DLS among school-age children with ASD. METHODS: A preliminary experimental research design (pre- and post-evaluation) was conducted from the beginning of May to the end of July 2023 on 31 children with ASD. The socio-economic status scale, Vineland Adaptive Behavior Scale, and Gilliam Autism Rating Scale were administered before and after a theory-based DLS training program. RESULTS: There was a significant difference in the DLS and motor functioning before and after the implementation of the training program (p < .001 and p = .021, respectively). In addition, there was a significant difference in the total score of autistic severity before and after the implementation of the training program (p < .001). CONCLUSION: The promising outcomes of the study indicate the need for further testing and expansion of this intervention. These findings contribute to the growing body of evidence highlighting the significance of DLS training program in the comprehensive treatment approach for children with ASD. Consequently, proposing DLS training programs as a cost-effective and efficient nursing intervention is warranted.

Using smart phone technology to improve daily living skills for individuals with intellectual disabilities.

BACKGROUND: Individuals with intellectual disabilities need continued supports in completing daily living tasks to increase the likelihood of achieving independence. Fortunately, research has shown that assistive technology, and particularly video prompting helps support independent living for individuals with intellectual disabilities. AIMS: This study investigated the efficacy of a highly customizable task analysis smartphone application in assisting three young adults with intellectual disabilities learn how to cook three different multistep recipes. MATERIALS & METHODS: Three young adults with intellectual disabilities enrolled in a four-year postsecondary education program (PSE) participated in a multiple probe design across participants to examine the effect of a Task Analysis app on the participants' completion of three cooking tasks. RESULTS: In this present study, the use of video prompting to teach a daily living skill resulted in large and meaningful effect size gains of 99%-100% for all three participants, as measured by Tau-U. DISCUSSION: Video prompting is an effective instructional strategy which allows the user to self-prompt and manage their ability to successfully complete daily living skills. In this current study, video prompting made a substantial difference in the safety of participants. CONCLUSION: The use of video prompting can decrease the reliance on others (e.g., teachers and caregivers), improve self-confidence of the user, and improve the user's level of autonomy.

Daily living skills of autistic adolescents and young adults: A scoping review.

INTRODUCTION: Daily living skills (DLS) are essential for an increased quality of life and autonomous living. DLS are a focus of occupational therapy practice; however, there has been no identified review of DLS acquisition in autistic adolescents or adults. A scoping review was undertaken of which the objective was to evaluate and synthesise the extent, range, and nature of research activity, and to identify research gaps in the existing literature as they relate to DLS acquisition and autistic adolescents and adults. METHODS: A structured search of the literature was conducted. Studies published in English between 2011 and 2021 that included a focus on the acquisition of DLS in autistic adolescents and young adults were included. The titles and abstracts of 103 records were screened, and the full text of 53 records was reviewed. These reference lists were hand searched. Following this process, 25 papers were found to meet the inclusion criteria. RESULTS: Findings indicate inconsistencies throughout the literature, with a lack of consensus on best practice methods, mediums, and/or tools to support optimal outcomes in terms of DLS acquisition for the autistic population. Themes related to (1) Generalisation of Skills Across Contexts, (2) Skill Maintenance, (3) Technology as a Teaching Method, (4) Participant and Family Perspectives, and (5) The Balance of Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) focus in research were extracted from the reviewed literature. There is a strong consensus in the findings of the identified papers that autistic adolescents and young adults experience poorer outcomes in terms of DLS acquisition than non-autistic peers, and peers with other developmental or intellectual disabilities. CONCLUSION: Future research is needed to fill these identified gaps and provide a clearer understanding on interventions to support optimal outcomes for autistic individuals.

Parental Occupation Executive Training (POET): An Efficient Innovative Intervention for Young Children with Attention Deficit Hyperactive Disorder.

Background: The American Academy of Pediatrics strongly recommends first-line treatment of preschool aged children with attention deficit hyperactivity disorder (ADHD) be parent- or teacher-administered behavior therapy.Aim: To assess the efficacy of Parental Occupation Executive Training (POET), a new intervention for young children with ADHD symptomatology.Materials and Methods: We implemented a controlled, counterbalanced design with a study and comparison group (72 children with mean age of 5.42 years identified as having ADHD symptomatology. using the DSM-IV and Conners Parents and Teachers Rating Scales). Intervention included parental-training sessions focused on children's occupational goals and capitalized on the assumed relationship between daily activities and executive functions. We evaluated achievement with the Canadian Occupational Performance Measure (COPM), Behavioral Rating Inventory of Executive Functions, and a questionnaire we developed related to parental knowledge and skills.Results: Executive functions and preselected daily functions significantly improved following the POET intervention. Parent perceptions related to their knowledge of their children's executive difficulties and appropriate management strategies changed significantly following the intervention, and significantly correlated with the COPM scores.Conclusions: A short-term parental training program, the POET improved daily functioning of young children with ADHD symptomatology by focusing on their parents' ability to cope with the children's executive delays.

Effects of a self-management training for people with intellectual disabilities.

BACKGROUND: To help people with intellectual disabilities lead a more independent life, it is important to promote their self-management. This study evaluated the effectiveness of a self-management training for people with intellectual disabilities directed at independent functioning in daily life. METHOD: In the training, 17 people with intellectual disabilities worked on personal self-management goals covering a wide range of everyday affairs. Primary outcome measures focused on goal attainment, independence and support needs. Moreover, outcomes regarding psychopathological behaviour and quality of life were explored. Data were collected before and at the start of the training, and 3, 6, 9 and 12 months later. RESULTS: The training contributed to the attainment of self-management goals and to the reduction in support needs (p < 0.01). There were no changes in independence, psychopathological behaviour and quality of life. CONCLUSIONS: Results indicate that the training supports people with intellectual disabilities to self-manage their daily affairs.

An assessment of health, social, communication, and daily living skills of adults with Down syndrome.

Adults with Down syndrome (DS) are surviving longer, yet data delineating life skills are lacking. As providers are encouraged to provide a "balanced" description of DS to family members/caregivers, more quantitative data are required to accurately describe the abilities and potential of adults with DS. This study assessed health, social, communication, and daily living skills of adults with DS to describe the range of abilities and to show how increasing age contributes to functional abilities. Caregivers of an adult with DS 20 years of age or older participated in an online questionnaire. Descriptive statistics and scores from scales assessed relationships between the number of health issues reported and functional abilities, and how the abilities changed as age increased. Of 188 participants, 157 completed the survey with partial results included. Communication, independence, and social activity scores were compared to the number of congenital and non-congenital health issues reported. Linear regression results showed those with more health issues were significantly less likely to be independent and social. However, only current health issues affected communication skills. No significant correlation occurred between the number of congenital abnormalities and scores for independence/life skills as an adult. T-test by age group found decreasing abilities after 40 years of age. In conclusion, quantitative data and information from this study is beneficial for providers in order to describe the potential for an individual with DS and to assist caregivers to plan accordingly for the future of their adult with DS.

Psychometric Properties of the Canadian Little Developmental Coordination Disorder Questionnaire for Preschool Children.

AIMS: Test the psychometric properties and cut-off scores for the Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ), which screens for coordination difficulties in children aged 3 to 4 years. METHODS: Parents of children with typical development (n = 108) and children at risk for motor problems (n = 245) completed the questionnaire. A subgroup (n = 119) of children was tested with the Movement Assessment Battery for Children-2 (MABC-2) and the Beery-Buktenica Developmental Test of visual-motor integration (VMI) to determine motor impairment (MI). RESULTS: Test-retest reliability (r = 0.956, p < .001) and internal consistency (Cronbach's alpha = 0.94) were high. Construct validity was supported by a factor analysis and significant difference in scores of children who were typically developing and were at risk. Concurrent validity was evaluated for the children who received standardized motor testing, with significant difference between children with and without MI. Discriminant function analysis showed that all 15 items were able to distinguish the two groups. The questionnaire correlated well with the MABC-2 and VMI. Validity as a screening tool was assessed using logistic regression modeling (X(2)(5) = 25.87, p < .001) and receiver operating curves, establishing optimal cut-off values with adequate sensitivity. CONCLUSIONS: The Little DCDQ is a reliable, valid instrument for early identification of children with motor difficulties.

Effect of cognitive intervention on children with ADHD.

Although not considered a diagnostic criterion in DSM-IV, motor difficulties in children with Attention Deficit Hyperactivity Disorder (ADHD) are commonly reported. Prevalence of co-morbidity of ADHD and Developmental Coordination Disorder is as high as 50%. Cognitive Orientation to daily Occupational Performance (CO-OP) is a problem-solving approach originally developed for children with Developmental Coordination Disorder. In this approach, therapists support children to use cognitive strategies in a process of guided discovery to solve occupational performance problems. A single case experimental design (multiple baselines) was used to examine the influence of a 12-week intervention using CO-OP with six children with ADHD. Outcome measures included the Canadian Occupational Performance Measure (COPM), Goal Attainment Scaling and the Bruininks-Oseretsky Test of Motor Proficiency and Performance (BOTMP). The results of this study demonstrated improvements in both goals and motor performance in the participants due to the intervention. These results provide some support for the use of CO-OP with children with ADHD. Further research into the application of CO-OP with children with ADHD is warranted based on these preliminary positive findings regarding the efficacy of this intervention to address motor-based performance difficulties.

Stability of parent report on Mobility and Self-Care item scores of the Pediatric Evaluation of Disability Inventory.

Secondary analysis using data from a clinical trial was performed to evaluate the stability of individual items of the Mobility and Self-Care functional skills scales of the Pediatric Evaluation of Disability Inventory (PEDI). Parents of 113 children aged 1-6 years old with cerebral palsy completed the PEDI twice by questionnaire 6 months apart. An item was classified "unstable" if the score changed from capable to unable. The number of children with more than five unstable items and the number of items with more than five children having unstable scoring patterns were calculated. Nineteen children (17%) and 13 items had unstable scoring patterns. The majority of PEDI items demonstrated stability of parent scoring. Examination of unstable items suggests that parents may need assistance in understanding the difference between "usual" and "best" performance, interpreting descriptors such as "thoroughly," and maintaining the same context reference for outdoor mobility items.

Mothers' experiences with the Pediatric Evaluation of Disability Inventory (PEDI).

Parents of a child with a disability are often asked about their child's functioning in daily activities. One way to gather this information is through parent-report functional questionnaires such as the Pediatric Evaluation of Disability Inventory (PEDI). The purpose of this study was to explore parental experiences associated with completion of the PEDI before and after a functional therapy intervention. Semi-structured interviews were conducted with 12 mothers of children with cerebral palsy (CP) or developmental delay (DD) who had completed the PEDI within a larger study. A content analysis approach was used to code and organize the data into five themes. PEDI completion was associated with increased parental awareness of developmental patterns, and greater insight into levels of assistance they give to their child. Parents described various challenges and concerns with the PEDI that have implications for test administration processes. The findings have potential to enable more sensitive and focused PEDI use.

A Meta-Analysis of Self-Management Interventions in Teaching Daily Living Skills to Autistic Individuals.

The current study aimed to conduct a systematic review and meta-analysis of self-management interventions for teaching daily living skills to autistic individuals. This study accessed the corresponding studies by doing a search in six databases. 14 articles and one dissertation met the inclusion criteria. The included studies were first analyzed descriptively and coded according to quality indicators using What Works Clearinghouse (WWC) standards. Second, the effect sizes of the included studies were calculated using two different effect size measures (i.e., Tau-U and performance-criteria-based effect size values [PCES]). Third, these analyses were also conducted for generalization and maintenance data. Of 15 studies included in this review, nine met the WWC standards with and without reservations. Tau-U analyses were conducted for 14 studies, whereas PCES values were calculated for only eight studies with mastery criteria. The findings indicated that the self-management interventions had a .93 CI95 (.80, 1) overall effect size for Tau-U with a very large effect. On the other hand, the overall effect size for the PCES values indicated a moderate effect with .99. The weighted effect sizes in generalization and maintenance phases were very large for Tau-U; however, moderate to high effects for PCES. Although self-management interventions showed diversity, one of the domains of daily living skills (i.e., community living skills) has not been studied in the field. Notably, among the studies in our review, the last ones are from 2019. Detailed findings from descriptive analyses and two different effect size calculations are discussed, and recommendations for future studies are given.

The relation between specific motor skills and daily living skills in autistic children and adolescents.

Introduction: Motor skill difficulties are common in autistic children and are related to daily living skills (DLS). However, it remains unclear which specific motor tasks are most likely to impact overall DLS. This study sought to fill this gap. Methods and results: In 90 autistic children and adolescents (ages 6-17 years), we found that fine/manual motor tasks, like drawing or folding, demonstrated significant medium-sized relations with DLS, even after accounting for IQ and sensory features, whereas tasks in the areas of bilateral coordination, upper-limb coordination, and balance only related to DLS (small effect sizes) prior to accounting for IQ and sensory features. When looking at an overall balance score, we found that IQ significantly interacted on the relation between overall balance and DLS. Discussion: These results further demonstrate the particular importance of fine/manual motor skills for DLS in autistic youth, even when accounting for IQ and sensory features. Indeed, accounting for sensory features strengthened the relations between fine/manual motor skills and DLS. Our findings provide evidence of the impact of cognitive factors on the relation between balance and DLS, indicating that it may be that autistic individuals with lower IQs experience relations between balance and DLS that are different than their peers with higher IQs. Our findings support the benefit of considering individual motor skills rather than domain-level information when assessing ways to promote DLS in autistic youth. The results further shed light on the importance of fine motor skills, as well as the unique relationship of balance and DLS in autistic individuals with lower IQs.

Sensorimotor Features and Daily Living Skills in Autistic Children With and Without ADHD.

Attention-deficit/hyperactivity disorder (ADHD) commonly co-occurs in autistic children. However, additional research is needed to explore the differences in motor skills and sensory features in autistic children with and without ADHD, as well as the impacts of these factors on daily living skills (DLS). This observational study sought to fill this gap with 67 autistic children (6.14-10.84 years-old), 43 of whom had ADHD. Autistic children with ADHD demonstrated higher sensory features and lower motor skills than autistic children without ADHD. In examining autism and ADHD features dimensionally, we found that overall sensory features, seeking, and hyporesponsiveness were driven by both autism and ADHD features, whereas motor skills, enhanced perception, and hyperresponsiveness were driven by only autism features. Additionally, in using these dimensional variables of autism and ADHD features, we found that differences in motor skills, sensory and autism features, but not ADHD features, impact DLS of autistic children, with autism features and motor skills being the strongest individual predictors of DLS. Together, these results demonstrate the uniqueness of motor skills and sensory features in autistic children with and without ADHD, as well as how autism features, sensory features, and motor skills contribute to DLS, emphasizing the importance of a comprehensive understanding of each individual and complexities of human development when supporting autistic children.

Factors that Influence the Daily Living Skills of Autistic Adults: The Importance of Opportunity.

While existing literature has demonstrated that Daily Living Skills (DLS) performance of autistic individuals is lower than what is expected of their age and cognitive abilities, limited studies have examined DLS in autistic adults. This study aimed to understand the influence of intellectual function (IQ) and contextual factors (i.e., provision of opportunities) on autistic individuals' DLS performance. Participants included 33 autistic individuals ranging in age from 16 to 35 years. Their caregivers were administered the Vineland Adaptive Behavior Scales, 3rd edition's (Vineland-3) caregiver interview form. A novel coding system was developed to capture the frequency of reasons for participants' non-performance of DLS tasks, based on caregiver's report. "Target" scores reflecting expected possible score if reasons for nonperformance could be addressed were computed. Qualitative analysis of parental responses indicated that, for adults with average or higher IQ, lack of opportunity to learn and/or implement the skill was the most frequent reason for not performing DLS. Lack of opportunity was also the second most common reason provided for adults with NVIQ below 85, following cognitive ability. Taking into account reasons for nonperformance, "Target" scores were, on average, 7.65 points higher for the NVIQ ≥ 85 group. These findings highlight a need for multi-dimensional assessment to go beyond individual strengths and difficulties to also include contextual factors that may influence adults' skill acquisition and performance. It is essential that clinicians ensure that adequate opportunities for learning and performance are available to promote acquisition of important DLS.

Piloting a Novel Daily Living Skills Assessment in Autistic Adolescents and Young Adults.

Background: There are a few ecologically valid measurements of Daily Living Skills (DLS)-a critical component of adaptive functioning (AF)-for autistic adolescents and young adults. This is particularly important given that DLS predict outcomes as autistic adolescents transition to adulthood. Methods: We pilot-tested the assessment section of two modules of the Computerized Functional Skills Assessment and Training program (CFSAT) in 25 autistic (n = 4 female) and 25 non-autistic (n = 6 female) adolescents and young adults to evaluate preliminary feasibility in an autistic sample. Tasks involved using an ATM and ticket-buying machine. We also assessed AF and DLS with a well-validated self-report questionnaire. We examined group differences in performance and relationships between performance on CFSAT and an existing measure of AF and DLS. We also conducted regression analyses to investigate the associations between age, IQ, executive functioning (EF), and CFSAT task performance. Results: All but one autistic participant were able to complete the CFSAT tasks. Autistic participants made more errors, but did not take longer to complete the task, than non-autistic participants. Performance correlated strongly with self-reported AF generally and DLS specifically. The regression analyses revealed that task performance was associated with EF in the autistic group, but not the non-autistic group. Conclusions: These results provide preliminary support for the use of a new performance-based ecologically valid assessment of DLS in an autistic population. Two CFSAT modules were well-tolerated and detected differences in DLS ability. Strong correlations with an existing measure of AF suggest evidence of construct validity. The EF was associated with CFSAT task performance in autistic individuals. Such a tool could help identify individuals who would benefit from a DLS intervention.

Why is this an important issue?: For autistic adolescents and young adults, one of the most important predictors of success after high school are daily living skills (DLS), which are a component of adaptive functioning (AF), or the ability to operate independently when engaged in day-to-day tasks. However, most of the measures used to assess these abilities are parent- or child-report questionnaires, which may lack objectivity. What was the purpose of this study?: The Computerized Functional Skills Assessment and Training program (CFSAT) is an innovative software program that was designed to teach people how to perform daily tasks that require the use of technology. This study piloted two CFSAT modules in a sample of autistic adolescents and young adults. The researchers wanted to see whether the program could be completed by the autistic participants and whether their performance related to an existing measure of DLS and other cognitive measures known to be related to AF. What did the researchers do?: This study piloted the assessment portion of two CFSAT modules in 25 autistic and 25 non-autistic adolescents and young adults to investigate whether it might be a useful measure of DLS skills in autistic individuals. The assessment portion of the program gives participants tasks to complete on a virtual ATM and Metro Ticket Kiosk and records time to completion and accuracy. Participants also used a questionnaire to self-report DLS and general AF and performed cognitive tasks. What were the results of the study?: All but one autistic participant were able to complete both tasks. The autistic group made more errors but did not take more time to complete the tasks compared with the non-autistic group. Performance on the CFSAT was related to self-reported DLS scores on a questionnaire and to scores on cognitive tasks. What do these findings add to what was already known?: Previous work recommended computer-based DLS programs for autistic individuals. Since our results suggest the CFSAT is a viable computer-based program of DLS for autistic adults, CFSAT could help fill a need for DLS tools that are more applicable to real life than currently available questionnaires. Findings provide preliminary support that the CFSAT assessment measures DLS and could be a promising program to further study. What are potential weaknesses in the study?: Weaknesses of our work include that the measures used in this study only assessed two specific tasks encountered in daily living. Data on participants' real-life experience were not fully collected, so the association between the amount of real-life experience on these tasks and computer task performance will require further study. No data asking whether the tasks studied are useful for autistic adolescents and adults were collected. The study was small and consisted of relatively fewer women, which means that results will need to be replicated in a larger sample. How will these findings help autistic adults now or in the future?: This work could eventually pave the way for interventions that improve DLS (including the training version of the CFSAT) that may be helpful for teaching autistic individuals technology-related functional skills.

A cluster analysis of daily living skills in school aged children with autism spectrum disorder.

For individuals with autism spectrum disorder (ASD) daily living skills (DLS) fall below chronological age and have been linked to factors such as language. Given the impact of DLS on daily life, it is critical to gain a comprehensive understanding of DLS profiles in children to guide effective treatment. Using a large dataset from the Autism Speaks Autism Treatment Network, the current study sought to (1) examine whether there are subgroups of children with ASD defined by both their Vineland-II DLS scores and language abilities and (2) explore the relationship between internalizing and externalizing symptoms on subgroups using the Child Behavior Checklist. A five-cluster solution was found, but one group was subsequently dropped. Four clusters were examined: Low Language-Low DLS (n = 143); Low-Language High DLS (n = 170); High Language-Low DLS (n = 189); and High Language-High DLS (n = 203). The High Language-Low DLS group had significantly higher internalizing and externalizing symptoms as compared to the other groups. The results highlight the importance of targeting DLS in school-age children with ASD, especially for those with comorbid internalizing and externalizing symptom to ensure that the gap between age and functional DLS does not continue to widen.

Microanalysis of Daily Living Skills in adolescents with Autism Spectrum Disorder without an intellectual disability.

Adolescents with autism spectrum disorder (ASD) without an intellectual disability (ID) have daily living skills (DLS) that fall below their chronological age and affect their ability to achieve successful adult outcomes, but little is known about their specific DLS challenges. Utilizing the Vineland Adaptive Behavior Scales, 3rd Edition (VABS-3) in a sample of 151 adolescents with ASD without an ID, we explored the VABS-3 DLS domain, subdomains, interview topics, and individual items. Results indicated that Community DLS was a relative strength, followed by Domestic DLS, and then Personal DLS. Adolescents with ASD demonstrated significant challenges in many age appropriate DLS subdomain interview topics and individual items, indicating a need for interventions to increase acquisition of DLS to improve adult outcomes.

Using an App-Based Token Economy to Increase Engagement in Daily Living and Vocational Tasks with Adults with Developmental Disabilities.

The token economy is an evidence-based practice that improves outcomes across populations, settings, and behaviors. Nonetheless, their complex nature frequently leads to ineffective implementation. In addition, little is known about the extent to which token economies are effective for increasing engagement in adults with disabilities. Therefore, we conducted a multiple probe across participants to evaluate the effectiveness of a token economy using an app (i.e., Class Dojo) to increase engagement with daily living and vocational tasks in adults with disabilities. All participants increased their engagement with tasks following the introduction of the intervention and maintained higher than baseline levels of engagement up to 6 weeks after the intervention ended. Staff members completed an anonymous survey to indicate their perception of the feasibility and effectiveness of the intervention. Social validity results indicated that some staff members found the intervention effective, but time-consuming and challenging.

[General aspects of dementia disorders]. / Allgemeine Aspekte demenzieller Erkrankungen.

The prevalence of dementia increases with age. In rare cases, people younger than 65 years old are also affected, with substantial consequences for the professional life. The symptoms depend on the form of dementia and can vary individually. Impairment of short-term memory is not always in the foreground and other neurocognitive domains, such as the disturbance of executive functions can have a significant impact on the ability to cope with everyday life. Pathophysiologically, neurodegenerative dementias with the major forms of Alzheimer's dementia, Lewy body dementia, and frontotemporal dementia are distinguished from vascular dementias. Mixed forms are common. There is no curative treatment, but progression can be slowed by nonpharmacological measures and, especially in Alzheimer's dementia, by pharmacological treatment. Appropriate measures can promote independence and autonomy for as long as possible; however, in the course of the disease restrictions in the extended activities of independent living will initially occur, such as banking transactions, use of means of transport and, in the further course, also in the basic activities of daily living. Legal capacity and the ability to consent to health interventions are restricted sooner or later; however, this must always be evaluated for the specific situation and is not generally the case with the diagnosis of dementia. Instruments such as living wills, identification of a health care proxy, and advanced care planning should be used at an early stage. To decrease family caregiver burden with the increased risk of developing depression, supportive, accompanying measures and education are of great importance.

Executive functions in daily living skills: A study in adults with autism spectrum disorder.

Introduction: Adults with autism and adults with schizophrenia show difficulties in adaptive skills, especially those related to daily functioning. Some studies suggest that adaptive skills are associated with deficits in executive functions (EF), while others indicate that intelligence quotient (IQ) might also play a role. Literature suggests that autistic symptoms further affect adaptive skills. The interest of the current study, therefore, was to explore to what extent IQ, EFs as well as core autistic symptoms predict adaptive skills. Methods: To do this, 25 controls, 24 adults with autism, and 12 with schizophrenia were assessed on IQ (Wechsler Adult Intelligence Scale), and executive functioning. The EF was measured with neuropsychological tasks (inhibition, updating, and task switching) and with the Dysexecutive-Spanish Questionnaire (DEX-Sp) which assessed everyday life EF problems. Core ASD symptoms were measured using the Autism Diagnostic Observation Schedule, the Autism Spectrum Quotient-Short version (AQ-S), and the Repetitive Behavior Questionnaire - 3 (RBQ-3). Results: The results indicated EF difficulties in both, autism and schizophrenia. The IQ explained a high percentage of the variance found in adaptive skills, but only in the autism group. We can conclude, therefore, that high IQ is associated with low adaptive skills levels and EFs affect adaptive functioning in people with autism; however, this does not explain the difficulties in adaptive functioning in the schizophrenia group. Core features of autism assessed with self-report questionnaires (but not the ADOS-2) predicted low scores on the adaptive skills, only in the autism group. Discussion: Both EF measures predicted adaptive skills scores in autism, but not in schizophrenia. Our results suggest that different factors affect the adaptive functioning in each disorder. For instance, the EFs should be a central focus for improvement, especially for individuals with autism.
