A challenge for registries of unrelated hematopoietic stem cell (HSC) donors is to recruit and retain sufficient donors for patients needing transplants. Many registered HSC donors opt-out when called as a potential match for a patient. Anecdotal evidence suggests that motives for joining a registry may be linked to the donation decision. The primary goals of this investigation were to describe the range of motives for joining a registry and to examine donor availability by motive type. A diverse sample of 357 potential HSC donors from the Anthony Nolan registry in the UK was asked about their motives for joining and their decision to continue or opt-out after matching a patient was recorded. Motives for joining (N = 557) were first coded and categorized into 17 specific motive types and then arranged along a spectrum from internal to external. Internal values-based motives were most prevalent and availability was highest among potential donors expressing these motives (92%) and lowest among those expressing external motives (pressure, incentives; 0%). Although further research is needed to confirm these findings, they suggest that registries should assess donors' motives for joining at recruitment in order to conduct follow-up to ensure commitment among those potential members expressing external motives.

The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
