Introduction

• Autism Spectrum Disorder (ASD) sometimes referred to as “autism”.

• It is “a chronic disorder whose symptoms include failure to develop normal social relations with other people, impaired development of communicative ability, lack of imaginative ability, and repetitive, stereotyped movements”

• Quality Of Life is a broad concept incorporating the person's physical health, psychological state, level of independence, social relationships, personal beliefs and their relationship to salient features of the environment.

• The importance of quality of life (QoL) is widely recognized in many fields, including economics, social sciences, and medicine.

• Measurement of QOL is important indicator.

• It is necessary for treatment purpose.

• Usually autistic children have lower quality of life in comparison to normally developing peers.

• In Bangladesh, measurement have not done yet.

Background information

• Autistic Disorder, Asperger’s Disorder and PDD- NOS are collectively known as Autism Spectrum Disorder. (DSM-5)

• Autism spectrum disorders (ASD) are complex neurodevelopment disorders characterized by qualitative impairments in three domains-

-Social interaction -Communication and -Repetitive, stereotyped behavior.

• About 1 in 68 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC's (ADDM) Network.

• ASD is almost 5 times more common among boys (1 in 42) than among girls.

• ASD has great impact on the affected child and his/her family's quality of life.

• Lifetime cost for an individual with ASD at $3.2 million.

Justification of the study

• 1 child in 500 in Bangladesh has autism.• Approximate number of children with ASDs in

Bangladesh is no less than 280,000.• General attitude towards autism is mostly

negative. • It is considered as a social barrier.• Treatment facility is not properly available.• Measurement of QOL have not done yet.

Research hypothesis:• Health related quality of life in children with

Autism Spectrum Disorder (ASD) is poor in comparison to normally developing peers in Bangladesh.

General objective:• To assess the HRQL in children with ASD (8-12

years) by using the Modified Pediatric Quality Of Life inventory 4.0 Generic Core Scale.

Specific objectives

• To estimate the socio-demographic characteristics of children with ASD.

• To assess the HRQL in children with ASD (8-12 years) by using the Modified Pediatric Quality Of Life inventory 4.0 Generic Core Scale from parent’s perspective.

• To assess the HRQL in normally developing peers by using the same scale and compare it with ASD children.

List of variables Independent variable:1) Variables related to socio-demographic status:• Age• Gender• Occupation of parents • Monthly family income of parents• Educational status of parents• Religion2) Autism Spectrum Disorder (ASD) Dependent variable:• Health related quality of life (HRQL)

Conceptual framework

Operational definitions

• Health: Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. (WHO)

• Quality of life: Individuals' perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns.(WHO)

• Children: The United Nations Convention On the Rights of the Child defines child as "a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier.

• Autism spectrum Disorder or autistic spectrum describes a range of conditions classified as neurodevelopmental disorder. (DSM-5)

Literature review

• Literature review was done appropriately by using

- Books - Journals - Magazines - Internet - Library documents etc.

Methods and materials

Study design: Cross sectional comparative study.Study population: Children age group 8-12 years, both ASD and

normally functioning peers.Study period: July 2015- December 2015. The total study

period was six months. A prior work schedule was prepared on the basis of different tasks.

Study locale

• 3 centers of Dhaka city which are dealing with autistic children.

1) Bangladesh Protibondhi Foundation (BPF), Kalyani.

2) SWID Bangladesh and its sister wing Ramna Protibondhi Shongstha.

3) Institute of Neuro-develpment and Research Centre.

For normally developed children the chosenstudy locales are: 1) Willes Little Flower School and College 2) Sky View Garden Apartment, and 3) Cordova International School and College

Sample size calculationSample size was calculated from study population by using the formula: n= z2pq / d2

Where, n= desired sample size. p= 0.5 (as there is no reasonable estimate of any prevalence rate, we use 50%). q = 1-p = 1-0.5 = 50% d = degree of error (absolute precision of the study assumed 0.05) z = the reliability co efficient at the 95% Confidence Interval = 1.96. Thus required sample size is 385.

Study sample

• Considering the complexity of the study and my definitive age group (8-12 years), my feasible study sample was 115.

• 57 ASD children and 58 normally developing peers were chosen as my study sample.

Eligibility criteria

Inclusion criteria:• Have one of the three ASD diagnoses (e.g.

autism disorder; pervasive developmental disorders, not otherwise specified; or Asperger disorder).

• Are not suffering from other complicated diseases.

• Parents of autistic child who are willing to provide data.

Exclusion criteria:• Are not diagnosed as ASD.• Suffering from other diseases• Parents of autistic child who are not willing to

provide data.

Development of Research Instrument• A semi structured interview questionnaire was

prepared.• Developed on the basis of relevant literature.• The questionnaire was pre-tested and evaluated

thoroughly.• Necessary revision and adjustment was done

accordingly.• It was prepared in both Bangla and English.• 80% were close ended & 20% were open ended

questions.

Data collection procedure• Data was collected from the parents in the

institution premises by face to face interview.• Two or three visits within a 4-week period at the

location of six study places were done.• During the first visit, eligibility criteria was

confirmed.• During the second visit, the PedsQL was

administered.• Interviewing the parents (either father or mother)

according to scale was required 20 min each.• In a day I collected data from 15 participants.

Data analysis• Data analysis was done according to the specific

objectives of the study.• Data was entered into computer using SPSS 20 version.• Then relationship between the variables was established

by mean, median, mode, standard deviation and t- test.• After that MLR (Multiple Logistic Regression) was done

to assess the strength of association between the variables.

• For inferential statistics, mainly one way ANOVA, and Pearson’s correlation was used.

• In all the tests p˂0.05 was considered to be statistically significant.

Data presentation & interpretation• Data was presented by: -Tables -Graphs -Chart -Statistical interference.• Easy demonstration was done for general understanding.

Results and Findings

• A cross sectional comparative study was carried out among 115 children, 57 of them were diagnosed as Autistic children.

• Data was collected from the parents of autistic and normal children.

• My respondents were very much cooperative and responded well.

• There was no missing data.• Data are presented through tables and figures.

Discussion• This study set out to increase our knowledge of

children with ASD’s HRQL compared to typically developing peers.

• Regarding HRQOF, I have found a significant poorer QOL in children with autism in comparison to normally developing peers from parent’s point of view by using Pediatric Quality Of Life inventory 4.0 Generic Core Scale.

• Higher mean value for variables ‘Physical Function’ , ‘Emotional Function’ , “Social Function” , ‘School Function’ indicates a lower quality of life .

• Chi square test was done and each of the 4 domains – total physical, emotional, social and school function shows significant difference as p value is less than 0.001.

• Multiple Logistic Regression was done to strengthen the association and that was also found statistically significant.

Data Quality Management• Data quality management was done in every

stages of research. • During the data collection in the field, data was

checked and re-checked for data consistency. • After the data entry, data was checked again for

ensuring there was no missing information as well as inconsistent by comparing the raw data and the entry data.

• Data filtration was also done again after the statistical test.

Study Limitations

• The study population was a specific group (8-12 years children) of the country, does not include all the age groups of ASD.

• Not merely represent the general population of the country.

• I did not include all the ASD children in our study, so the study did not contain the overall HRQL of ASD children.

Ethical issues

• Ethical clearance was obtained from the university authority.

• Informed written consent (ICF) was taken.• Data secrecy part was assured to every

participant. • No one had been forced to provide data unless

they give it deliberately.• Privacy of the respondents was maintained

during data collection.

Conclusion• This study is the first to estimate HRQL in

children with ASD in Bangladesh as compared to normally developed peers, from the parent’s point of view.

• Children with ASD reported having lower HRQL than peers, which was confirmed by parents.

• Autism Spectrum Disorder has been, and continues to be, a major health issue in our current society.

• This study will help the policy makers contribute in implementing different strategies for improving health status of autistic children.

Recommendation

• Improve educational Setting.• Improve functional Skills.• Individualized Educational Plan (IEP) should be

incorporated.• Training should be provided to teachers, aides,

and therapists.• Providing education to family members.• Siblings should also be monitored.
