Results from the blood donor competence, autonomy, and relatedness enhancement (blood donor CARE) randomized trial.

Background: This study aimed to promote competence, autonomy, and relatedness among first-time whole blood donors to enhance intrinsic motivation and increase retention.

Study Design And Methods: Using a full factorial design, first-time donors (N = 2002) were randomly assigned to a no-treatment control condition or to one of seven intervention conditions designed to promote donation competence, autonomy, relatedness, a combination of two (e.g.

An automated motivational interview promotes donation intention and self-efficacy among experienced whole blood donors.

Background: Interventions intended to motivate donors to return can be costly and time consuming. The current study examined the effect of a Web-based automated interview, informed by motivational interviewing and self-determination theory, on donor intention, motivation, and behavior in a sample of highly experienced donors.

Study Design And Methods: Approximately 1 week after donating, 1177 highly experienced whole blood donors (mean prior donations, 35.

A motivational interview promotes retention of blood donors with high internal motivation.

Background: Based on the hypothesis that self-determined motivation is associated with an increased likelihood of future behavior, the present study examined the ability of a motivational interview to promote internal motivation for giving blood and future donation attempts.

Study Design And Methods: A sample of 484 recent whole-blood and double red blood cell donors (62.4% female; age = 30.

Buccal telomere length and its associations with cortisol, heart rate variability, heart rate, and blood pressure responses to an acute social evaluative stressor in college students.

Objective: Understanding the relationship between stress and telomere length (a marker of cellular aging) is of great interest for reducing aging-related disease and death. One important aspect of acute stress exposure that may underlie detrimental effects on health is physiological reactivity to the stressor.

Methods: This study tested the relationship between buccal telomere length and physiological reactivity (salivary cortisol reactivity and total output, heart rate (HR) variability, blood pressure, and HR) to an acute psychosocial stressor in a sample of 77 (53% male) healthy young adults.

A brief motivational interview promotes internal motivation to donate blood among young adults with and without a prior donation history.

Background: Recruitment and retention of first-time and repeat donors is essential to maintain a stable blood supply. Recent evidence has shown that promoting internal motivation may be an effective strategy to enhance donation behavior. We tested the efficacy of an in-person motivational interview at increasing internal motivation and intention to donate.

A brief motivational interview with action and coping planning components enhances motivational autonomy among volunteer blood donors.

Background: In contrast to standard donor retention strategies (e.g., mailings, phone calls, text messages), we developed a brief telephone interview, based on motivational interviewing principles, that encourages blood donors to reflect upon their unique motivators and barriers for giving.
