About this study

Official title: The Role of Vulnerability and Responsiveness in Cardiovascular Disease Biomarkers Associated With Loneliness

The study evaluates the impact of vulnerable self-disclosure and perceived responsiveness in individuals across levels of loneliness. Participants will be randomized to a high disclosure or a low disclosure condition.

Read the detailed description

Recent studies have found that loneliness has the same impact on morbidity and mortality as smoking cigarettes and twice that of obesity. One proposed pathway by which loneliness impacts morbidity and mortality is through cardiovascular disease. Loneliness is regularly associated with increased sympathetic nervous system and decreased parasympathetic nervous system engagement, both reliable biomarkers of increased risk of cardiovascular disease. One possible explanation for the this phenomena is that individuals who experience loneliness experience meaningful disruptions to the interpersonal process where they fail to disclose when appropriate or react to other individuals disclosure. This may result in engagement of nervous system regulation of social behaviors resulting in both in the moment and long term engagement of the sympathetic nervous system. The proposed 2-year research plan will examine the behaviors and nervous system reactions of individuals across loneliness levels in an experimental condition that manipulates the probability of engaging in relationship building behaviors.

This study will recruit 60 individuals aged 18-25 who are fluent in English and report no history of cardiovascular or respiratory disease to participate in a study investigating social interactions. While a specific level of loneliness is not an inclusion variable, to ensure representation across loneliness levels, the investigators will screen for levels of loneliness and invite individuals to participate equally distributed between 4 levels of loneliness: 1 or more standard deviations below the mean, between 0-1 standard deviations below the mean, between 0-1 standard deviations above the mean, and 1 standard deviation or more above the mean.

The study will then utilize a 2x2 factorial design splitting participants into reporting above or below the mean level of loneliness and randomizing those individuals to a behavioral task condition that involves answering either a high disclosure or low disclosure set of questions. Before engaging in the behavioral task, participants will fill out a series of questionnaires assessing their current social functioning. Participants will then have baseline levels of sympathetic nervous system and parasympathetic nervous system engagement measured. In an ongoing way, throughout the behavioral task, participants will have their of sympathetic nervous system and parasympathetic nervous system engagement measured. Every 15 minutes, the behavioral task will stop and participants will complete a series of questionnaires assessing their evaluation of their behavior with the research assistant in the task, as well as feelings of connection they are experiencing with the research assistant. At the conclusion of the behavioral task, participants will be invited back to participate in the condition they had not previously completed with a new research assistant. All behavioral tasks will be coded by trained research assistants assessing third party evaluation of relationship building behaviors.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High self-disclosureOther

    The high self-disclosure condition involves individuals asking and answering a series of questions that are more personal in nature and involve sharing or receiving information that is likely to be emotionally laden and information that is not readily shared in typical conversations. An example of a question from this condition includes "If you were to die today without the chance to speak with anyone, what would you most regret not having said to someone? Why haven't you said it yet?"

  • Low self-disclosureOther

    The low self-disclosure condition involves individuals asking and answering a series of questions that are not personal in nature and involve sharing or receiving information that is shared in very casual conversations. An example of a question from this condition includes "What did you do to celebrate Halloween last year?"

Low loneliness, low self-disclosureExperimentalIndividuals in this arm report lower levels of loneliness than the mean level reported by similar individuals. They will start the study in the low self-disclosure group which involves questions that are unlikely to involve meaningful personal disclosure. All members of this group will also complete the high self-disclosure condition later in the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Respiratory Sinus Arrhythmia

    Respiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration. RSA is considered a reliable way to measure parasympathetic innervation of the heart mediated by the vagus nerve.

    Measured: 50 minutes

  2. Electrodermal Activity

    Electrodermal activity (EDA) is the property of the body that results in variation in the electrical characteristics of the skin. It is thought that skin resistance varies as a function of the state of sweat glands in the skin and that sweating is controlled by the sympathetic nervous system. Consequently, EDA is viewed as a non-invasive measure of sympathetic nervous system activity.

    Measured: 50 minutes

Secondary outcomes (1)
  1. Self-reported Feelings of Connection

    The Social Connectedness Scale: Research Assistant. The minimum score on the measure is 6, the maximum is 36. Higher scores on the measure indicate more feelings of connection. The measure is a composite of 6 questions assessing feelings of connection reported by the participant. All 6 questions are measured on a scale of 1-6.

    Measured: 50 minutes

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 29 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: University affiliation changed and I was unable to transfer the grant that was funding the project). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Respiratory Sinus Arrhythmia (time frame: 50 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2022.
