Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Psychological and Sociocultural Causes of Schizophrenia

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Ethnic Identity within a Larger Culture

Ethnic Identity within a Larger Culture

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in situations...

Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

Summary

Children born to mothers from Sub-Saharan Africa show higher autism rates and more severe symptoms. This migrant group also has increased cognitive disability and family history of autism, warranting further research.

Pediatrics

Background:

Autism Spectrum Disorder (ASD) diagnosis rates and presentation can vary across populations.
Understanding demographic and ethnic variations in ASD is crucial for targeted interventions.

Purpose of the Study:

To investigate if children of immigrant mothers have higher autism rates compared to the indigenous population.
To explore symptom severity, demographics, and ethnicity in children diagnosed with ASD from immigrant backgrounds.

Main Methods:

Retrospective case note analysis of 366 children presenting to a pediatric developmental service.
Data collected between 2007 and 2009 at the Adelaide and Meath incorporating the National Children's Hospital, Tallaght, Ireland.
Comparison of ASD diagnosis rates and characteristics between children of mothers from Africa, other countries, and Ireland.

Main Results:

Autistic Spectrum Disorder (ASD) was diagnosed in 131 children; speech and language delay in 132.
Children of African-born mothers (16%) showed higher rates of moderate/severe cognitive disability (72.2%) compared to the Irish cohort (16.3%).
The African cohort exhibited higher heritability, with 36.9% reporting a positive family history of autism versus 26.3% in the Irish cohort.

Conclusions:

An observed increase in ASD rates among migrant populations, particularly those from Sub-Saharan Africa.
This specific migrant cohort presents with more severe manifestations of ASD.
Further epidemiological validation is recommended to identify potential etiological risk factors.
