“Blood for Blood”? Personal Motives and Deterrents for Blood Donation in the German Population
(2021)
Purpose
A setting-sensitive instrument for assessing Quality of Life (QoL) in Telemedicine (TM) was unavailable. To close this gap, a content-valid “add-on” measure was developed. In parallel, a brief index was derived featuring six items that summarise the main content of the multidimensional assessment. After pre- and pilot-testing, the psychometric performance of the final measures was investigated in an independent validation study.
Methods
The questionnaires were applied along with other standardised instruments of similar concepts as well as associated, yet disparate concepts for validation purposes. The sample consisted of patients with depression or heart failure, with or without TM (n = 200). Data analyses were aimed at calculating descriptive statistics and testing the psychometric performance on item, scale, and instrument level, including different types of validity and reliability.
Results
The proposed factor structure of the multidimensional Tele-QoL measure has been confirmed. Reliability coefficients for internal consistency, split-half, and test-retest reliability of the subscales and index reached sufficient values. The Tele-QoL subscales and the index demonstrated Rasch scalability. Validity of both instruments can be assumed. Evidence for discriminant construct validity was provided. Known-groups validity was indicated by respective score differences for various classes of disease severity.
Conclusion
Both measures show convincing psychometric properties. The final multidimensional Tele-QoL assessment consists of six outcome scales and two impact scales assessing (un-)intended effects of TM on QoL. In addition, the Tele-QoL index provides a short alternative for outcome assessment. The Tele-QoL measures can be used as complementary modules to existing QoL instruments capturing healthcare-related aspects of QoL from the patients’ perspective.
Quality of life (QoL) is a core patient-reported outcome in healthcare research, alongside primary clinical outcomes. A conceptual, operational, and psychometric elaboration of QoL in the context of TM is needed, because standardized instruments to assess QoL do not sufficiently represent essential aspects of intended outcomes of telemedical applications (TM). The overall aim is to develop an instrument that can adequately capture QoL in TM. For that purpose, an extended working model of QoL will be derived. Subsequently, an instrument will be developed and validated that captures those aspects of QoL that are influenced by TM. The initial exploratory study section includes (a) a systematic literature review, (b) a qualitative survey for concept elicitation, and (c) pre-testings using cognitive debriefings with patients and an expert workshop. The second quantitative section consists of an online expert survey and two patient surveys for piloting and validation of the newly developed instrument. The resulting questionnaire will assess central experiences of patients regarding telemedical applications and its impact on QoL more sensitively. Its use as adjunct instrument will lead to a more appropriate evaluation of TM and contribute to the improvement of care tailored to patients’ individual needs.

Introduction: To maintain a sufficient donor pool, deferred first-time donors (FTD) should be motivated to return for blood donation. This pilot study investigates how deferral affects momentary mood, satisfaction with the donation process, and subsequent return behavior to examine their potential for motivating (deferred) FTD. Methods: All of the subjects (n = 96) completed a first questionnaire (A1) before pre-donation assessment. Deferred FTD (n = 22) were asked to complete a second questionnaire (A2) immediately after deferral, while non-deferred FTD (n = 74) filled in the second questionnaire (A3) after blood donation. The impact of deferral, momentary mood, and satisfaction with the donation process on return behavior within 12 months was tested by calculating two path analyses, controlling for sex and age. Results: Mood (p < 0.001) and satisfaction with social aspects of the donation process (p = 0.01) were decreased after deferral. Deferred FTD were less likely than non-deferred FTD to return to the blood donation center within 12 months (60.8 vs. 36.4%; p = 0.043). However, path analyses revealed that deferral effects on mood and satisfaction were not connected to return behavior. Instead, age had a significant influence on return behavior (p < 0.05) such that, overall, non-returning FTD were older than returning FTD, regardless of their deferral status. Conclusion: Our findings suggest that mood and satisfaction with the donation process are directly affected by deferral but not clearly responsible for low return rates. It seems promising to embed these variables in established health behavior models in further studies to increase the return rates of deferred FTD.
Quality of Life (QoL) is a core patient-reported outcome in healthcare research. However, a conceptual, operational, and psychometric elaboration of QoL in the context of telemedical care (TM) was needed, as standardised instruments to assess QoL do not comprehensively represent essential aspects of intended outcomes of TM. Therefore, the overall aim of this thesis was to conceptualise QoL in the context of TM and to develop an instrument that can adequately assess QoL in TM.
