TDIs, CATIs and WATIs for Healthcare Market Research

Market research is an important aspect of any business, including the healthcare industry. The use of different data collection methods, such as TDIs, CATIs, and WATIs, can be helpful in obtaining valuable insights and understanding consumer behavior in healthcare.

TDIs, CATIs, and WATIs are three commonly used methodologies in healthcare market research. These methods are used to collect data from healthcar5e professionals, patients, and other stakeholders to help inform strategic decision-making for healthcare companies. In this blog post, we will discuss each of these methods in more detail.

TDIs (Telephonic Depth Interviews)

TDIs, or telephonic depth interviews, are one-on-one interviews conducted over the phone. This method is often used to collect data from healthcare professionals, such as doctors, nurses, and other healthcare providers. The interviewer typically uses a semi-structured interview guide to ask open-ended questions and follow-up questions to explore the interviewee’s opinions and experiences in greater depth.

One advantage of TDIs is that they can be conducted quickly and efficiently, without the need for travel or in-person meetings. This makes them a cost-effective option for healthcare companies looking to collect data from a geographically dispersed group of participants. However, it is important to note that TDIs may not be suitable for all types of research, as some participants may be more comfortable sharing their opinions face-to-face.

CATIs (Computer Assisted Telephone Interviews)

CATIs, or computer-assisted telephone interviews, are similar to TDIs in that they involve one-on-one interviews conducted over the phone. However, CATIs differ in that they use a computer program to guide the interviewer through the interview process. This program may include pre-determined questions, skip patterns, and other features to ensure that the interview is conducted consistently and accurately.

One advantage of CATIs is that they allow for more complex survey designs than TDIs. For example, they can incorporate branching logic and other advanced features to ensure that participants are only asked questions that are relevant to them. Additionally, CATIs can be used to collect large amounts of data quickly and efficiently, which can be useful for healthcare companies looking to gather data from a large sample of participants.

WATIs (Web Assisted Telephone Interviews)

WATIs, or web-assisted telephone interviews, are a combination of CATIs and online surveys. In a WATI, the interviewer uses a web-based program to guide the interviewee through a survey while conducting the interview over the phone. This method allows for more complex survey designs and can be used to collect both quantitative and qualitative data.

One advantage of WATIs is that they allow for greater control over the interview process, as the interviewer can see the participant’s responses in real-time and tailor the interview accordingly. Additionally, WATIs can be more engaging for participants than traditional telephone interviews, as they incorporate visual elements like images and videos.

Advantages of Using TDIs, CATIs and WATIs for Healthcare Market Research

Telephone-based surveys have been a popular method of collecting data for market research for many years. Within the realm of telephone-based surveys, there are several different types of surveys that can be conducted, including telephone depth interviews (TDIs), computer-assisted telephone interviews (CATIs), and web-assisted telephone interviews (WATIs). Here are some advantages of each for healthcare market research:

TDIs (Telephone Depth Interviews): TDIs are conducted with a single respondent over the telephone, and they are often used to gather detailed, qualitative data about a specific topic. One of the main advantages of TDIs is that they allow the researcher to delve deeply into a respondent’s experiences and opinions, which can be particularly useful in healthcare research where there may be complex medical issues or sensitive topics that require careful exploration. TDIs can also be more flexible than other types of telephone surveys, as the interviewer can tailor the questions to the respondent’s individual situation and adapt the conversation as needed.

CATIs (Computer-Assisted Telephone Interviews): CATIs are similar to TDIs, but they are typically more structured and quantitative in nature. One of the main advantages of CATIs is that they allow for faster data collection and analysis compared to traditional paper surveys, as the interviewer can use a computer program to record responses in real-time. This can be particularly useful for healthcare market research studies that require a large sample size or are time sensitive.

WATIs (Web-Assisted Telephone Interviews): WATIs combine the convenience of online surveys with the personal touch of telephone interviews. Respondents are typically invited to participate in a survey online, and then they are contacted by phone to complete the interview. One of the main advantages of WATIs is that they allow for greater respondent anonymity and can increase the response rate for sensitive topics, as respondents may feel more comfortable disclosing personal information over the phone rather than in an online survey. Additionally, WATIs can be more cost-effective than traditional telephone surveys, as they eliminate the need for costly call centres and reduce interviewer time.

Disadvantages of using TDIs, CATIs and WATIs for Healthcare Market Research

TDIs (Telephone Depth Interviews), CATIs (Computer-Assisted Telephone Interviews), and WATIs (Web-Assisted Telephone Interviews) are commonly used methods for conducting healthcare market research. However, there are several disadvantages associated with these methods:

Limited sample: TDIs and CATIs require participants to have access to a phone, while WATIs require access to a computer and internet connection. This can limit the sample to certain demographics or exclude individuals who do not have access to these resources.

Lack of personal interaction: TDIs, CATIs, and WATIs all lack the personal interaction that can occur during in-person interviews. This can lead to a lack of rapport and trust between the interviewer and participant, potentially affecting the accuracy and depth of the responses.

Response bias: Because the interviews are conducted remotely, participants may not feel as comfortable providing honest or detailed responses. Additionally, participants may not fully understand the questions being asked, leading to inaccurate or incomplete responses.

Limited visual aids: In contrast to in-person interviews, TDIs, CATIs, and WATIs do not allow for the use of visual aids such as product samples, prototypes, or medical devices. This can limit the depth and accuracy of responses.

Technology issues: Technical issues such as poor internet connection or malfunctioning equipment can disrupt or end the interview prematurely, leading to incomplete data collection.

Data quality issues: The quality of data collected through TDIs, CATIs, and WATIs can be affected by issues such as poor recording quality, difficulty in transcription, or inadequate data cleaning.

Difficulty in establishing rapport: Establishing a connection and building rapport with participants can be difficult in remote interviews, especially if the interviewee is not a skilled communicator.

In conclusion, TDIs, CATIs, and WATIs are all valuable tools for healthcare market research. The choice of methodology will depend on the specific research question and the target audience, as well as other factors like cost and time constraints. By using these methods effectively, healthcare companies can gather insights that will inform strategic decision-making and ultimately improve patient outcomes.
