which research method should be used to gather data on the pathological liars and their spouses

What are your choices?

First you need to determine what question about them you are trying to answer. That would influence the method used to gather your data.

However, if you are dealing with pathological liars, it would not be advisable to use any type of questionnaire to be filled out by these people — unless you have away to compare their answers to actual behavior.

I hope this helps. Thanks for asking.

To gather data on pathological liars and their spouses, there are several research methods that could be used. Here are three common approaches:

1. Surveys and Questionnaires: This method involves developing surveys or questionnaires to collect information from both the pathological liars and their spouses. The surveys can include questions about their behaviors, experiences, and relationships. This method allows for a large amount of data to be collected from a wide range of individuals in a relatively efficient manner.

To conduct a survey or questionnaire study, you would need to design the questions based on the specific research objectives and ensure they are valid and reliable. Then, you would need to identify a suitable sample of pathological liars and their spouses, which can be challenging given the sensitivity of the topic. Finally, you would need to distribute the survey and collect the responses. Online platforms or in-person interviews can be used for data collection.

2. Interviews: Conducting interviews can provide more in-depth and qualitative data about pathological liars and their spouses. This method involves selecting a sample of individuals to participate in one-on-one or group interviews. Open-ended questions can be asked to allow participants to share their experiences, emotions, and perspectives.

To conduct interviews, you would need to identify potential participants and arrange interviews with them. You would then need to develop an interview guide with relevant questions and prompts to guide the discussion. Interviews can be recorded and transcribed for analysis.

3. Case Studies: A case study approach can be used to gain a comprehensive understanding of specific individuals or couples affected by pathological lying. This method involves intensive data collection through various sources, such as interviews, observations, and document analysis.

To conduct a case study, you would need to identify individuals or couples who are willing to participate and provide consent. Multiple data sources, such as interviews with the individuals and their spouses, possible observations of their behaviors, and analysis of relevant documents, would be utilized. This method requires careful and detailed analysis of the collected data to derive meaningful insights.

Before implementing any research method, it's essential to consider ethical considerations, participant recruitment strategies, data analysis techniques, and the resources available for the study. Additionally, consulting with experts in the field or a research advisor can provide valuable guidance on selecting the most appropriate research method and ensuring the study's validity and reliability.
