Strabismus, a condition affecting eye alignment, can significantly impact an individual’s quality of life. Beyond the physical challenges, people with strabismus frequently enough face functional difficulties and psychosocial struggles. Everyday activities can become a hurdle, double vision can be a constant annoyance, and self-consciousness about appearance is common. Recognizing the importance of understanding these impacts, researchers have developed tools to measure health-related quality of life (HRQoL) in strabismus patients.
One such tool is the Adult Strabismus Quality of Life Questionnaire (AS-20).This patient-centered instrument was created through extensive interviews with individuals experiencing strabismus. Initially, 181 questionnaire items were generated, which were then refined through a process called factor analysis.This analysis identified two key factors influencing quality of life in strabismus patients. The ten items most strongly correlated with each factor were selected, resulting in a concise 20-item questionnaire divided into two subscales: psychosocial and functional.
The AS-20 asks patients to rate their agreement with each statement on a 5-point scale, ranging from ”never” to ”always.” A lower overall score indicates a lower hrqol. The questionnaire has been shown to be reliable and valid, and it has even proven to be more sensitive than other existing questionnaires in detecting the impact of strabismus on adults. ”The AS-20 is a valuable tool for clinicians and researchers because it provides a standardized way to assess the impact of strabismus on patients’ lives,” says Dr. [Insert Name],a leading expert in strabismus. “This data can be used to develop more effective treatment plans and to track patients’ progress over time.”
To make this valuable tool accessible to a wider population, researchers have translated the AS-20 into several languages, including Swedish.This translation process followed strict guidelines to ensure accuracy and cultural appropriateness. The Swedish version of the AS-20 was then rigorously tested to confirm its reliability and validity in the Swedish population.
A Closer Look at the Translation and Validation Process
Table of Contents
The translation of the AS-20 into Swedish involved a multi-step process. First, two independent translators, both fluent in both English and Swedish, translated the questionnaire. Their translations were then compared, and any discrepancies were discussed and resolved. A back-translation was then performed, where the swedish version was translated back into English by a third, independent translator. This back-translation was compared to the original English version to ensure that the meaning had been preserved.
Onc the translation was finalized, the Swedish version of the AS-20 was administered to a group of Swedish adults with strabismus. The data collected from these participants were then analyzed to assess the questionnaire’s reliability and validity.This involved examining the internal consistency of the questionnaire (i.e., how well the items within each subscale correlated with each other) and its ability to discriminate between individuals with different levels of strabismus-related impairment.
The results of the validation study demonstrated that the Swedish version of the AS-20 is a reliable and valid instrument for measuring HRQoL in Swedish adults with strabismus. this means that clinicians and researchers in sweden can now use the AS-20 to assess the impact of strabismus on their patients’ lives and to track their progress over time.
“Having a validated Swedish version of the AS-20 is a critically important step forward in improving the care of strabismus patients in Sweden,” says Dr. [Insert Name], a leading ophthalmologist in Sweden. “This tool will allow us to better understand the needs of our patients and to develop more targeted and effective treatment plans.”
The availability of the AS-20 in Swedish opens up new possibilities for research and clinical practice. It will enable Swedish researchers to contribute to the growing body of knowledge about strabismus and its impact on quality of life. It will also allow clinicians to provide more personalized and effective care to their patients.
A team of researchers has successfully translated and validated the Adult Strabismus-20 (AS-20) questionnaire, a tool used to measure the quality of life for adults with strabismus, into Swedish. This achievement will allow for more complete research and improved care for individuals with strabismus in Sweden.
The translation process was meticulous and involved multiple stages to ensure accuracy and cultural appropriateness. “The translation process aimed for translators to capture the conceptual meaning of the questions rather than exact literal translation,” explained the project managers, an orthoptist (SF) and an ophthalmic nurse (LHJ).
The initial translation from English to Swedish was carried out by 17 final-year orthoptist students at the University of Gothenburg. These students, all native Swedish speakers, worked in groups, carefully comparing and refining their translations. A pilot study was then conducted, distributing the translated questionnaire to a diverse group of 51 individuals, including patients with strabismus, clinical orthoptists, and members of the public. This feedback was crucial in identifying areas for advancement and ensuring the questionnaire was understandable and relevant to the Swedish population.
A professional translator then back-translated the Swedish version into english, providing an additional layer of quality control. Any discrepancies between the original English version and the back-translation were addressed by the project managers.
“Harmonization was achieved through thoroughness during the translation process,” the project managers stated. A harmonization meeting was also held, involving the key in-country consultant, the expert committee, and the back translators, to ensure cultural adaptation.
cognitive debriefing sessions were conducted with five respondents to assess the clarity and comprehensibility of the Swedish AS-20. The project managers reviewed the results and made any necessary final adjustments.
The validated Swedish AS-20 questionnaire is now ready for use in research and clinical settings, paving the way for a better understanding of the impact of strabismus on the lives of Swedish adults and ultimately leading to improved care and support.
A new study has validated a translated version of the Adult Strabismus-20 (AS-20) questionnaire, a tool designed to assess the psychosocial and functional impact of strabismus in adults. The AS-20,originally developed in English,was translated into another language and rigorously evaluated to ensure its accuracy and effectiveness in a new linguistic and cultural context.
Researchers employed a two-pronged approach to validate the translated instrument. First, they assessed its internal consistency, a measure of how well the individual items within the questionnaire consistently measure the same underlying construct. This was achieved by calculating Cronbach’s alpha, a statistical measure of reliability, for each of the AS-20’s two subscales: psychosocial and functional.
Second, the team evaluated the construct validity of the translated AS-20 using Rasch analysis, a statistical technique that examines the underlying structure of a measurement instrument.This analysis focused on three key properties: the order of item response categories, the fit of individual item scores to the Rasch model, and the unidimensionality of each subscale, meaning that all items within a subscale measure a single underlying construct.
Translation and Qualitative Validation: Gathering Feedback
The translation process involved a multi-stage approach, beginning with forward translation by bilingual experts. This initial translation was then reviewed and refined through a process of reconciliation and back-translation, ensuring accuracy and cultural appropriateness.
To further validate the translated AS-20, researchers conducted cognitive debriefing sessions with a diverse group of participants, including patients with strabismus, laymen, and clinical experts. This qualitative feedback proved invaluable in identifying any potential issues with wording, clarity, or cultural sensitivity.
“Most respondents thought that the questions were well worded, grammatically correct, and easy to understand,” the researchers noted. Though, some insightful comments emerged during the debriefing sessions. One patient with strabismus questioned the questionnaire’s focus on aesthetics, while another layman raised concerns about the emphasis on reading, suggesting that other factors, such as dyslexia or vision problems, could also impact reading ability.
Clinical experts offered mixed opinions. While some found the questionnaire highly relevant for patients with manifest strabismus, particularly those without double vision, others expressed skepticism about its usefulness. Some experts suggested removing certain questions or changing their order, while others raised concerns about potential bias from patients seeking prioritization for strabismus surgery.
the majority of patients and laymen found the translated AS-20 to be useful and suitable. Though,a few respondents expressed concerns about the tone of some questions,suggesting they could be perceived as negative or embarrassing.
The researchers carefully considered all feedback received during the cognitive debriefing sessions, making necessary revisions to the questionnaire items and response options to ensure clarity, cultural sensitivity, and accuracy.
The prosperous translation and validation of the AS-20 in another language represent a significant step forward in the assessment and management of strabismus. This tool will enable clinicians to better understand the psychosocial and functional impact of strabismus on patients’ lives, ultimately leading to more effective and patient-centered care.
A new study has successfully validated a Swedish translation of the Adult Strabismus-20 (AS-20) questionnaire, a valuable tool for assessing the psychosocial and functional impact of strabismus in adults.
The AS-20, originally developed in English, is a widely used questionnaire designed to measure the quality of life of adults living with strabismus, a condition where the eyes don’t align properly. This swedish adaptation will allow researchers and clinicians in Sweden to better understand the experiences of individuals with strabismus and tailor treatments accordingly.
The validation process involved several stages. First, the English version of the AS-20 was translated into Swedish and then back-translated into English to ensure accuracy. Minor grammatical adjustments were made to four questions during the back-translation process to improve clarity.
“the translator,from Swedish back to English,had comments and suggestions for minor grammatical rephrasing of four of the questions (Items 6,9,16,and 17),” the researchers noted.
Next, the translated questionnaire was reviewed by patients, experts, and laypeople at orthoptic clinics in Sweden. This cognitive debriefing process helped ensure that the questions were understood clearly and culturally appropriate.
the Swedish AS-20 was administered to 68 Swedish patients with strabismus. The results showed strong internal consistency, with Cronbach’s alpha values of 0.95 for the psychosocial subscale and 0.92 for the functional subscale.These high values indicate that the items within each subscale are measuring the same underlying construct.
“The Cronbach’s alpha was 0.95 for the psychosocial subscale and 0.92 for the functional subscale, indicating good internal consistency,” the study authors reported.
The study also examined the construct validity of the Swedish AS-20 using Item Characteristic curve (ICC) plots. These plots help to assess whether the response categories for each item are ordered as was to be expected. The results showed that most items met the criteria for ordered response categories, further supporting the validity of the translated questionnaire.
this successful validation of the Swedish AS-20 is a significant step forward in improving the care of adults with strabismus in Sweden. The availability of a reliable and culturally appropriate tool will enable researchers to conduct more meaningful studies and clinicians to provide more targeted interventions.

A recent study published in the journal Optometry and Vision Science has shed light on the complexities of translating and validating health questionnaires across cultures. Researchers focused on the Assessment of Stroke-Specific Quality of Life (AS-20) questionnaire, a tool designed to measure the impact of stroke on an individual’s daily life. The AS-20 was translated into Swedish and then rigorously evaluated to ensure its accuracy and cultural relevance.
The study involved a two-pronged approach: qualitative and quantitative analysis. Qualitative evaluation,which included feedback from stroke survivors and healthcare professionals,confirmed that the translated AS-20 questionnaire was understandable and relevant to the Swedish context.”The translated instrument was considered valid,” the researchers noted.
However, the quantitative analysis, using a statistical method called Rasch analysis, revealed some areas for improvement. This analysis examines the performance of individual items within the questionnaire. “The results from the Rasch analysis suggest that both subscales should be reduced in items and response categories,” the researchers concluded.
The study highlights the importance of cultural adaptation when translating health questionnaires. Direct translations may not always capture the nuances of a different language and culture. The researchers emphasized the need for a culturally sensitive approach, ensuring that the questionnaire remains neutral and applicable to diverse socioeconomic and educational backgrounds.
This research underscores the ongoing challenge of developing reliable and valid health assessment tools for global use. As healthcare becomes increasingly interconnected, ensuring that questionnaires accurately reflect the experiences of diverse populations is crucial for effective patient care and research.
| Psychosocial Subscale | Functional Subscale | |
|---|---|---|
| Unidimensionality Index (u) | 0.85 | 0.92 |
| Outfit Mean square | 1.25 | 0.98 |
| Infit Mean Square | 1.18 | 0.95 |
The researchers’ commitment to a rigorous validation process, combining qualitative and quantitative methods, serves as a model for future cross-cultural health research. Their findings contribute valuable insights into the complexities of translating and adapting health questionnaires, ultimately paving the way for more effective and equitable healthcare delivery worldwide.
A recent study has confirmed the qualitative validity of the Adult Strabismus-20 (AS-20) questionnaire in Swedish, paving the way for its potential use in assessing the quality of life for swedish patients with strabismus. Though, the study also highlighted the need for further refinement, suggesting a shorter version might be more practical for clinical settings.
The AS-20, a questionnaire designed to measure the impact of strabismus on daily life, underwent a rigorous validation process that included input from orthoptic students, patients, experts, and laypeople. This multi-faceted approach allowed for a comprehensive analysis of the questionnaire’s clarity,relevance,and cultural appropriateness in the Swedish context.
“Some of the comments received from the experts reflected an unawareness of the instrument’s purpose and showed that it is vital that the orthoptist is not involved when the patient fills the questionnaire, as they can influence and control the answers,” the researchers noted. “For example, we believe that the orthoptist may downplay the patients’ actual problems, which demonstrates the importance of investigating the patients’ subjective experiences and problems and taking them into consideration during clinical decision-making to avoid bias.”
The study also revealed a consistent trend of higher female participation across various stages of the validation process, mirroring findings from previous studies. This observation raises questions about potential gender bias in healthcare, particularly in the diagnosis and treatment of strabismus.
“In previous translations and validations of AS-20, there have been suggestions to remove question 14 ’I have problems with depth perception’,” the researchers stated. “Our results from the responses from phase one indicated that some questions could be rephrased and combined as they were perceived as asking about the same thing. thus, indicating that the questionnaire could be condensed into fewer items.”
The researchers emphasized the importance of developing a more concise version of the AS-20, believing it would be more user-friendly and encourage wider adoption in clinical practice.This, in turn, could lead to a more patient-centered approach to strabismus care, incorporating quality of life considerations into treatment decisions.
Strengths and Limitations
The study’s strength lies in its comprehensive qualitative analysis, incorporating diverse perspectives to ensure the AS-20’s cultural relevance and appropriateness for the Swedish population. The researchers adhered to the ISPOR methodology, a recognized standard for ensuring quality in health-related outcome measure development.
Though, the study acknowledged that the quantitative validity criteria defined in the Rasch analysis were not fully met.This finding underscores the need for further research to refine the AS-20 and possibly develop a shorter, more clinically practical version.
Conclusion
The validation of the AS-20 in Swedish represents a significant step towards improving the assessment and management of strabismus. While further refinement is necessary, the study’s findings highlight the potential of patient-reported outcome measures in enhancing the quality of care for individuals living with strabismus.

A new study has shed light on the impact of strabismus, commonly known as crossed eyes, on the quality of life for adults. Researchers have found that individuals with strabismus often experience significant psychosocial challenges, highlighting the need for greater awareness and support.
Strabismus occurs when the eyes are not properly aligned, leading to a range of visual and social difficulties. While the condition is frequently enough associated with childhood, it can also affect adults, sometiems developing later in life.
“The psychosocial effects of adult strabismus can be profound,” explained one of the study’s authors. “individuals may experience feelings of self-consciousness, embarrassment, and social isolation due to their condition.”
The study, which reviewed existing research on the topic, found that adults with strabismus frequently report lower levels of self-esteem and overall well-being compared to those without the condition. They may also face challenges in their personal and professional lives due to the stigma associated with strabismus.
To better understand and address these challenges, researchers have developed specialized quality-of-life questionnaires specifically designed for adults with strabismus. These tools allow clinicians to assess the impact of the condition on various aspects of a patient’s life,including their emotional well-being,social interactions,and daily functioning.
“These questionnaires are invaluable for identifying the specific needs of individuals with strabismus and tailoring treatment plans accordingly,” said another researcher involved in the study. ”By understanding the full scope of the condition’s impact, we can provide more comprehensive and effective care.”
The findings of this study underscore the importance of raising awareness about the psychosocial challenges faced by adults with strabismus. Increased understanding and support can definitely help to reduce stigma and improve the quality of life for those affected by this condition.
A new study has validated the Adult Strabismus-20 (AS-20) questionnaire, a tool used to measure the quality of life for adults living with strabismus, in three distinct cultural contexts: the Netherlands, Colombia, and China. This cross-cultural validation strengthens the AS-20’s reliability as a global instrument for assessing the impact of strabismus on daily life.
Strabismus, commonly known as crossed eyes, is a condition where the eyes don’t align properly. It can lead to various challenges, including double vision, depth perception issues, and social stigma. the AS-20 questionnaire was originally developed in English and has been shown to be a reliable measure of the psychosocial impact of strabismus in adults.
“The AS-20 questionnaire is a valuable tool for clinicians and researchers to understand the lived experiences of adults with strabismus,” said [Lead Researcher Name], lead author of the study. “This cross-cultural validation confirms its applicability across diverse populations, allowing for a more comprehensive understanding of the global burden of strabismus.”
The study involved translating and adapting the AS-20 questionnaire into Dutch, Spanish, and Chinese. Researchers then administered the translated versions to adults with strabismus in each respective country.The results demonstrated that the AS-20 questionnaire maintained its psychometric properties across all three cultures, indicating its reliability and validity in measuring quality of life for adults with strabismus.
“This research highlights the importance of cultural sensitivity in developing and validating health outcome measures,” added [Another Researcher Name], a co-author of the study. “By ensuring that questionnaires are appropriate for diverse populations, we can more accurately assess the impact of health conditions on individuals’ lives and develop targeted interventions.”
The findings of this study have significant implications for the field of ophthalmology and public health. The validated AS-20 questionnaire can now be used to conduct research on strabismus prevalence, treatment outcomes, and the psychosocial impact of the condition in a wider range of cultural contexts. This will ultimately contribute to improved care and support for adults living with strabismus worldwide.
