Objective: This study seeks to evaluate the psychometric properties of the Ottawa Self-Injury Inventory-Functions (OSI-F) for assessing nonsuicidal self-injury (NSSI), a condition for further study in the DSM-5. Participants: Participants included 345 students who indicated a history of self-injury in a university counseling center over six…

Using parent and expert focus…

The purpose of the present study was to examine the psychometric properties of the Chinese version of the Acceptance and Action Questionnaire-II (AAQ-II) across two samples of Chinese college students (n = 183 and n = 366) and a sample of elite Chinese athletes (n = 330). Exploratory and confirmatory factor analyses supported the existence of a…

An instrument was developed to assess the perceived learner-teacher transactional distance in the context of the Hellenic Open University and to provide psychometric evidence of reliability and validity of the interpretation of the scores derived from the scale. First, an elicitation study gathered information on students' beliefs and feelings…

Advances in technology have increased the likelihood that engineers will have to work in a global, culturally diverse setting. Many schools of engineering are currently revising their curricula to help students to develop cultural competence. However, our ability to measure cultural dispositions can be a challenge.
