Validation of the Spanish Version of the VERITAS-PRN Scale to Assess Adherence to on Demand Regimens in Patients with Hemophilia.

ABSTRACT:

Introduction

The episodic or on-demand administration of clotting factor concentrates in hemophilia patients in the event of hemorrhage is employed to restore hemostasis. Adherence to on-demand treatments needs to be assessed in order to improve patient management, avoiding adverse effects and serious clinical complications.

Aim

To validate the Spanish version of the treatment adherence scale in patients with hemophilia, namely, Validated Hemophilia Regimen Treatment Adherence Scale-PRN (VERITAS-PRN).

Methods

Eighty-five patients were recruited in three hemophilia patient associations in Spain. The VERITAS-PRN scale was adapted through a back-translation process from English to Spanish. A native Spanish bilingual translator translated the scale from English to Spanish, and subsequently another native English bilingual translator translated the scale from Spanish to English. The scale was applied twice (two months apart) to assess test-retest reliability.

Results

Internal consistency reliability was slightly lower in the VERITAS-PRN in Spanish (0.80) versus the English version (0.85). There were no differences (p > 0.05) between the means of the dimensions or in the total scores between the sample of patients in Spain and the USA. The test-retest reliability coefficient of the scores on the total scale was 0.80 [CI, 0.74-0.86]. The test-retest reliability coefficient was greater than 0.90 in all subscales.

Conclusion

The Spanish version of VERITAS-PRN has high consistency and empirical validity. This scale is useful for assessing the degree of adherence to treatment in adult patients with hemophilia following episodic infusion treatment.

Project description:Lucid dreaming, a specific phenomenon of dream consciousness, refers to the experience being aware that one is dreaming. The primary aim of this research was to validate a Spanish version of the Lucidity and Consciousness in Dreams scale (LuCiD). A secondary aim was to explore whether meditation experience and mindfulness trait were related to LuCiD scores. Data from 367 Spanish men (34.6%) and women (65.4%) who completed LuCiD, the Five Facets of Mindfulness Questionnaire (FFMQ), and the Positive and Negative Affect Schedule (PANAS) were examined. From the total sample, 40.3% indicated some experience with formal meditation (meditators), while 59.7% did not have any meditation experience (non-meditators). A random subsample of 101 participants, who completed LuCiD for a second time after a period of 10-15days, was used for test-retest reliability analysis. The LuCiD scale comprises 28 items distributed across eight factors: insight, control, thought, realism, memory, dissociation, negative emotion, and positive emotion. Factor structure, reliability by both internal consistency and test-retest reliability, and construct and concurrent validity were tested. Confirmatory factor analysis (CFA) confirmed the original eight-factor model, showing goodness of fit in contrast to a single-factor model. Item 15 was deleted from the Dissociation factor as it performed poorly (i.e., skewness and kurtosis, non-normal distribution of responses, and corrected item-total correlation under 0.40). The scale showed adequate values of internal consistency (between α=0.65 for Memory and α=0.83 for Positive Emotion) and test-retest reliability by significant Pearson correlations (p<0.001) for each factor. The scores of meditators were higher for the LuCiD scale Insight and Dissociation factors, in contrast to those of non-meditators. The Observing facet of mindfulness was positively associated with all LuCiD factors, except Realism and Positive Emotion, and the Acting with Awareness facet showed a negative correlation with the LuCiD factor Realism. Finally, positive and negative affects was associated with the LuCiD factors Positive Emotion and Negative Emotion. This study provides a valid and reliable measure for exploring lucidity and consciousness in dreams for a Spanish population, Moreover, the results suggest a relationship with meditation experience, mindfulness trait, and positive and negative affect.
