Study Details

Study Description

Brief Summary

There is a pressing national need to provide higher-quality, more effectively accessible language interpretation services to improve the health outcomes of Americans who have limited English proficiency (LEP). This project addresses a critical component of this problem: The need to improve access to high quality, mental health services for diverse populations by improving the flow of clinical work across care settings (primary care and specialty care) through the use of innovative online asynchronous methods of language interpretation and clinical communication. The investigators are conducting a two phase study. The first phase is completed and involved developing and testing the interpreting tool. The second phase of the research is a clinical trial to compare two methods of cross-language psychiatric assessment.

Detailed Description

The investigators propose to develop and test a novel automated asynchronous interpretation tool. The proposed project builds on previous research, piloting the automated asynchronous interpretation tool. This 5-year project will be conducted in two phases. In Phase 1 the investigators iteratively evaluate and refine the automated asynchronous interpretation tool already developed in prior studies. In Phase 2, the investigators evaluate this tool using a two-group randomized cross-over trial. Investigators compare:

Method A (current gold standard of in-person real-time interpreting practice). A Spanish-speaking patient is diagnostically assessed in-person by an English-speaking psychiatrist through a Spanish-speaking interpreter.
Method B (comparative practice - ATP). A Spanish-speaking patient is interviewed in Spanish by a trained mental health interviewer. The interview is recorded in real time, translated into English using the automatic interpretation tool and adding sub-titles to the video file, and sent to an English-speaking psychiatrist to asynchronously - that is, at a later time - review the video and make a diagnosis.

All patients will undergo evaluation by both methods. Half of the patients will be randomized to be assessed by Method A first, followed by Method B and half to be assessed by Method B first, followed by Method A. The specific aims of the study are :

Aim 1: To iteratively evaluate and refine the automated asynchronous interpretation tool already developed in prior studies.
Aim 2: To compare patient satisfaction of Method A vs. Method B.
Aim 3: To compare the diagnostic accuracy and psychiatrist inter-rater reliability of Method A vs. Method B and demonstrate psychiatrist inter-rater reliability for Method B.
Aim 4: To compare the interview and language interpretation quality and accuracy of Method A vs. Method B.

Intervention/Treatment

Other: Method A first then Method B

Conventional in-person interview with a psychiatrist with a live human interpreter with crossover to asynchronous telepsychiatry

Behavioral: Active comparator: Human interpreter

A Spanish-speaking patient is diagnostically assessed in-person by an English-speaking psychiatrist through a Spanish-speaking interpreter.

Behavioral: Intervention: Asynchronous Telepsychiatry

A Spanish-speaking patient is interviewed in Spanish by a trained mental health interviewer. The interview is video-recorded in real-time, automatically translated into English with sub-titles added to the video file, and sent to a psychiatrist and to 3 English-speaking psychiatrists to asynchronously review the video and make a diagnosis.

Outcome Measures

Primary Outcome Measures

Diagnostic accuracy [Measured at one time point by each psychiatrist, once both methods of interviews are completed in one day]
Diagnosis accuracy with respect to gold standard SCID for Method B will be evaluated against Method A.
Diagnostic Inter-rater reliability [Measured at one time point by each psychiatrist, once both methods of interviews are completed in one day]
Using independent assessments from four psychiatrists for each of the 100 method B interviews the investigators will also examine inter-rater reliability of Method B diagnosis.

Secondary Outcome Measures

Satisfaction ratings [Measured at one time point by each psychiatrist, once both methods of interviews are completed in one day]
Satisfaction ratings from patients' questionnaires
Interview and language interpretation quality [Measured at one time point by each psychiatrist, once both methods of interviews are completed in one day]
All 200 interviews in both methods will be video recorded and the audio transcribed. The investigators will measure and compare the two interview methods interpretation quality through perception of interpretation quality
Interview and language interpretation accuracy [Measured at one time point by each psychiatrist, once both methods of interviews are completed in one day]
All 200 interviews in both methods will be video recorded and the audio transcribed. The investigators will measure and compare the two interview methods accuracy through the presence of medical errors, and the presence of language errors
