Development and Implementation of a Digital Textbook Platform Usability Assessment Instrument

Usability is the characteristic of a software product of being effective and efficient and producing satisfaction for users and traditionally is assessed through questionnaires but most of them are only available in English. A software usability assessment questionnaire (SUAQ) is proposed in two languages: Spanish and English. The methodology comprises four stages: 1) questionnaire development, 2) administration, 3) statistical validation, and 4) sample size determination. Twenty items were evaluated in terms of clarity, consistency, and relevancy. Then, the SUAQ was administered to 95 respondents. Overall, reliability values were acceptable in Spanish and English version, respectively. The factor analysis was feasible since the KMO index, and the Bartlett sphericity test was statistically significant. Both versions of SUAQ were tested to determine their validity. The findings show that the proposed methodology is an effective usability assessment instrument and thus an effective software improvement tool from a bilingual approach.

Background: the involvement of the potential end users in the development processes is a relevant issue for the acceptance of Ambient Assisted Living (AAL) products and services. Objective: this study aimed to use the conceptual framework of the International Classification of Functioning, Disability and Health (ICF) to conceptualize instruments for the different phases of the AAL development processes. Methods: personas and scenarios were modified, considering the fundamental concepts of the ICF in order to highlight end user's functioning and health conditions, and an ICF based instrument for usability assessment was defined and validated. Results: the results of several observational studies suggest the adequacy of the ICF based instruments (personas and scenarios and usability assessment instrument). Conclusion: the present study indicates that the ICF based instruments can be useful tools for the development of Ambient Assisted Living products or services.

Abstract. The study examines the relationship between a categorical and a dimensional personality assessment instrument in patients with Chronic Fatigue Syndrome (CFS). A total of 162 CFS patients were included in the study (91.4% women; mean age 47.5 years). All subjects completed the Spanish versions of the Personality Diagnostic Questionnaire-4+ (PDQ-4+) and the Temperament and Character Inventory-Revised (TCI-R). Results: 78 (48.1%) of the patients presented a Personality Disorder (PD), the most frequent being Cluster C, specifically Obsessive-compulsive disorder, followed by Avoidant disorder. PDs showed a specific pattern of correlation with temperament scales. All PD clusters correlated positively with Harm Avoidance and Self-Transcendence, and negatively with Reward Dependence, Self-Directedness, and Cooperativeness. In a logistic regression analysis, Self-Directedness and Cooperativeness predicted PD presence. The findings are consistent with previous studies in non-CFS samples and suggest that the combination of the Temperament and Character dimensions (low Self-Directedness and Cooperativeness and high Harm Avoidance and Self-Transcendence) correlates with PD severity, and that Self-Directedness and Cooperativeness are associated with PD presence in CFS patients. The integration of these two perspectives expands the current comprehension of personality pathology in CFS patients.
